Description

[001] Related Applications

[002] This application is a divisional of the Australian designation of PCT / IB2025 / 055540, filed 29 May 2025, the entire contents of which are incorporated herein by reference.

[003] Technical Field

[004] This invention relates, inter alia, to an animal drafter for drafting animals, particularly livestock such as sheep and cattle. In particular, the invention concerns a manually operated animal drafter comprising a manually operable actuator that controls the positioning of draft gates of the drafter to open and close exits of the drafter.

[005] Background Art

[006] An animal drafter is used in the management of livestock, to sort animals into different groups based on specific criteria such as weight, size, age, or health status. For some commercial drafters, animals enter a holding pen of the drafter one at a time through an entry of the holding pen. Once confined (trapped) within the holding pen the animal is then, according to predetermined criteria (eg. such as the weight of the animal, determined by weighing the animal within the holding pen), identified as belonging to a particular animal group based on those predetermined criteria. Then, based on those criteria, the drafter directs the trapped animal to one of three or more different exits of the holding pen.

[007] For other commercial drafters, animals enter the drafter from a crush or other holding pen one at a time through an entry of the drafter. Prior to entering the drafter, the trapped animal is identified as belonging to a particular animal group based on predetermined criteria. Based on those criteria, the drafter directs the trapped animal to one of three or more different exits of the drafter.

[008] Selection of the appropriate drafter exit can be carried out manually or automatically, depending on the whether the drafter is manually operated or automatically operated. Some drafters are fully automated and can handle the entire drafting process with minimal human intervention. For drafters that are manually operated (‘manual drafter’), these require a person to manually select the appropriate exit for the animal.

[009] Three-way manual drafters typically have an entry, three exits, and at least two draft gates which are positionable relative to the exits. Positioning of the draft gates is carried out manually by an operator of the drafter who determines which of the three exits the animal should exit.

[010] Typically, 3-way manual drafters have a first lever or other type of actuator operably connected to a first of the draft gates, enabling that first draft gate to be positioned by a person operating the first lever so as to unobstruct a particular exit, as well as a second lever or other type of actuator operably connected to a second of the draft gates, enabling that second draft gate to be positioned by the person operating the second lever so as to unobstruct a different exit. 2025263798   05 Nov 2025

[011] A disadvantage of these types of drafters is that the person operating the drafter is required to operate at least two different actuators such as levers.

[012] Object of the Invention

[013] It is an object of one or more embodiments of the present invention to provide a manually operated animal drafter that minimises or overcomes the disadvantage mentioned above.

[014] Alternatively, it is an object of one or more embodiments of the present invention to provide the public with a useful commercial choice of manually operated animal drafter.

[337] Best Modes for Carrying Out the Invention

[338] In the Figures, like reference numerals refer to like features.

[339] Referring first to Figures 1 to 8, there is shown an animal drafter 10 for drafting livestock such as cattle and sheep.

[340] A centrally extending longitudinal axis 100 divides the drafter 10 into left (L) and right halves (R), and so left and right descriptors (L, R) will be used to distinguish between like pairs of components such as left and right drafting gates, left and right gas dampers, left and right slotted lever assemblies etc. Note that ‘left’ and ‘right’ are used relative to a front end 103 of the drafter 10, when viewed from the front end 103 of the drafter 10.

[341] The drafter 10 includes a drafter chute 1 (drafter body 1), two draft gates 2L, 2R, a manually operated actuator 3, and an entrance chute 4.

[342] The drafter chute 1 includes a drafter chute body 11, a drafter chute entry 12 and three drafter chute exits 13, 14, 15. The drafter chute body 11 includes a front end 110, a rear end 111, a left side 112, a right side 113, an interior 114, a top 115, and a bottom 116. The entry 12 is located at the front end 110, a rear exit 13 is located at the rear end 111, a left side exit 14 is located at the left side 112, and a right side exit 15 is located at the right side 113. The drafter chute body 11 is cuboid, elongate when viewed in plan, and sized to permit passage of one animal at a time through its interior 114.

[343] The drafter chute body 11 is predominantly constructed of a tubular framework. The front end 110 includes a substantially rectangular frame 110, having a centrally located opening that provides the entry 12. The rear end 111 comprises a substantially rectangular frame 111, having a centrally located opening that provides the rear exit 13. The left side 112 includes a substantially rectangular frame 112, having a centrally located opening that, when unobstructed, provides the left side exit 14. The right side 113 comprises a substantially rectangular frame 113, having a centrally located opening that, when unobstructed, provides the right side exit 15.

[344] The drafter 10 comprises the centrally extending longitudinal axis 100 extending from the rear end 110 to the front end 111 of the drafter chute body 11 and further through the entrance chute 12 (see Figures 7 and 8).

[345] The left 112 and right sides 113 of the drafter chute body 11 each comprise a substantially vertical plane extending through the respective substantially rectangular frame 112, 113.

[346] Each draft gate 2L, 2R is in the form of a swing gate. Each draft gate 2L, 2R is mounted to a respective substantially rectangular frame 112, 113 of the drafter chute body 11, for rotation about a vertical axis relative to the drafter chute body 11. The draft gates 2L, 2R are mounted adjacent to the rear end 111 of the drafter chute body 11. 2025263798   05 Nov 2025

[347] As seen in Figures 5 and 6, each draft gate 2L, 2R includes a frame 20R, 20L and horizontally rails 21R, 21L extending within the frame 20R, 20L. Each draft gate 2L, 2R includes a vertically extending shaft 22L, 22R (or shaft pieces 22L, 22R) connected to the frame 20L, 20R, the ends 22L, 22R of which are mounted to the rectangular frame 112, 113 of the drafter chute body 11 using mounts 23L, 23R. The draft gates 2L, 2R are substantially identical to each other.

[348] As best seen in Figures 5, 6, 9, 12 and 18, a gate flange 24R, 24L is connected to an upper end of each shaft 22L, 22R (or shaft piece 22L, 22R) of each draft gate 2L, 2R and extends laterally of the shaft 22L, 22R above the frame 20L, 20R of the draft gate 2L, 2R.

[349] Each gate 2L, 2R is positionable between a closed position (as seen in Figures 1 to 8) and an open position (as seen in Figures 9 to 14). In the closed position, the draft gates 2L, 2R extend within the centrally located openings of the left 112 and right sides 113 of the drafter chute body 11, within substantially vertical planes of the left 112 and right sides 113 of the drafter chute body 11. In this way, the draft gates 2L, 2R close those left side 14 and right side exits 15. In the open position, the draft gate 2L, 2R moves out of alignment with that vertical plane, crossing into the interior 114 of the drafter chute body 11.

[350] Each draft gate 2L, 2R includes a gate locking mechanism 25L, 25R for locking each draft gate 2L, 2R in the closed position, as best seen in Figures 1, 5 and 6. The gate locking mechanism 25L, 25R has a locking bolt that locks the drafting gate 2L, 2R to its respective rectangular frame 112, 113 when in the closed position.

[351] The entrance chute 4 extends from the drafter chute entry 12, substantially in line with the centrally extending longitudinal axis 100. The entrance chute 4 includes a pair of spaced apart sidewalls 40L, 40R extending from the drafter chute entry 12, each proved by a horizontally extending upper frame member 400L, 400R and access door 41L, 41R. The entrance chute 4 includes a walkway 42 for an animal located between the pair of spaced apart sidewalls 40L, 40R.

[352] Each access door 41L, 41R is mounted to the substantially rectangular frame 110 of the drafter chute body 11, for rotation about a vertical axis relative to the drafter chute body 11. The access doors 41L, 41R are mounted to the front end 110 of the drafter chute body 11.

[353] As best seen in Figures 5 and 6, each access door 41L, 41R includes a frame 43L, 43R and horizontally rails 44L, 44R extending within the frame 43L, 43R. Each access door 41L, 41R includes a vertically extending shaft 45L, 45R (or shaft pieces 45L, 45R) connected to the frame 43L, 43R, the ends 45L, 45R of which are mounted to the rectangular frame 110 of the drafter chute body 11 using mounts 46L, 46R. The access doors 41L, 41R are substantially identical to each other, except the right access door 41R further has a rubber infill 47R, which can, for example, fill a void between the drafter 10 and a crush (not shown). 2025263798   05 Nov 2025

[354] Each access door 41L, 41R is positionable between a closed position (as seen in Figures 1 to 8) and an open position (as seen in Figure 19). In the closed position, the access doors 41L, 41R extend within the vertical planes of the left 112 and right sides 113 of the drafter chute body 11. In the open position, the access doors 41L, 41R move out of alignment with those vertical planes, crossing into the walkway 42 or opening outwardly, away from the longitudinally extending central axis 100.

[355] Each access door 41L, 41R includes a door locking mechanism 48L, 48R for locking each access door 41L, 41R in the closed position. The door locking mechanism 48L, 48R comprises a spring-loaded slam latch 48L, 48R that locks the access door 41L, 41R to its respective horizontally extending upper frame member 400L, 400R when in the closed position.

[356] The drafter 10 includes reinforcement in the form of braces and gussets 101, only some of which have been labelled.

[357] The drafter chute 1, draft gates 2L, 2R, entrance chute 4 and various other parts and components are primarily made of metallic tubular frame members and rails (galvanised steel, steel alloy, aluminium).

[358] The manually operated actuator 3 is operably connected to the two draft gates 2L, 2R, and enables selective positioning of the two draft gates 2L, 2R relative to the exits 13, 14, 15. The actuator 3 is hand operated.

[359] The actuator enables 3 selection of the following positions: Position (I), wherein the rear exit 13 is open, and the left 14 and right side exits 15 are closed by the left 2L and right draft gates 2R respectively - shown in Figure 20 (a); Position (II), wherein the left side exit 14 is open, and the rear exit 13 is closed by the left draft gate 2L and the right side exit 15 is closed by the right draft gate 2R -shown in Figure 20 (b); and Position (III), wherein the right side exit 15 is open, and the rear exit 13 is closed by the right draft gate 2R and the left side exit 14 is closed by the left draft gate 2L - shown in Figure 20 (c).

[360] The actuator 3 includes a hand-operated lever 30 and a linkage mechanism 5 as best seen in Figures 15 to 18. The hand-operated lever 30 is operably connected to the linkage mechanism 5 and the linkage mechanism 5 is operably connected to both draft gates 2L, 2R.

[361] The hand-operated lever 30 includes a substantially linear shaft 31 that has a free end and a fixed end. A handle 32 is located at the free end and a crankshaft connecting end 33 is located at the fixed end. The hand-operated lever 30 extends downwardly from the top frame member 400L of the entrance chute 4. The linear shaft 31 has an upper part coupled to a lower part by way of a spring-loaded coupling 34, and these linear shaft 31 parts can be selectively decoupled by an operator such that the hand-operated lever 30 is no longer effectively operably connected to the linkage mechanism 5. 2025263798   05 Nov 2025

[362] As seen primarily in Figures 7, 8, 11 and 14 to 18, the linkage mechanism 5 includes a crank mechanism, transforming rotational motion into reciprocating motion, enabling movement a draft gate 2L, 2R from Position (I) to Position (II) or from Position (I) to Position (III).

[363] The linkage mechanism 5 further includes a reverse motion linkage mechanism for moving a draft gate 2L, 2R from Position (I) to Position (II) or from Position (I) to Position (III).

[364] The linkage mechanism 5 further includes a draft gate return mechanism that assists with returning a draft gate 2L, 2R from Position (II) or Position (III) to Position (I).

[365] The linkage mechanism 5 further includes a housing 6 for housing various components of the linkage mechanism 5. Most hidden components of the linkage mechanism 5 are best seen in Figures 15 to 17 - omitting the housing 6 - and in Figure 18.

[366] The crank mechanism is operably connected to the hand-operated lever 30 and to the reverse motion linkage mechanism, the reverse motion linkage mechanism is operably connected to the draft gates 2L, 2R, and the draft gate return mechanism is operably connected to the draft gates 2L, 2R and to the reverse motion linkage mechanism.

[367] The linkage mechanism 5 further includes draft gate catches 59L, 59R capable of releasably coupling with the housing 6 of the drafter body 11 so as to maintain a draft gate 2L, 2R in Position (II) or Position (III).

[368] As seen in Figure 18, the linkage mechanism 5 further includes gate-connecting levers 70L, 70R equipped with lever-locking mechanisms (lock and release mechanisms) 7L, 7R. The lever-locking mechanisms 7L, 7R are each configurable between a locked position (locked configuration) and unlocked position (released configuration). In the locked position (locked configuration), the gateconnecting levers 70L, 70R pivot with the draft gates 2L, 2R and the actuator 3 is able to position the draft gates 2L, 2R, and in the unlocked position (released configuration) the draft gates 2L, 2R pivot independently of the gate-connecting levers 70L, 70R and the actuator 3 is unable to position the draft gates 2L, 2R.

[369] The linkage mechanism 5 also includes mounts 60 (collars, bushes, plain bearings or sleeve bearings - only some of which have been labelled) that mount, for example, the crankshaft 50 for rotation relative to the drafter chute 1 and entrance chute 4, parallel with the centrally extending longitudinal axis 100 of the drafter 10.

[370] The crank mechanism includes a rotatable crankshaft 50 operably connected to the end 33 of the hand-operated lever 30, and a crank 51 connected to the crankshaft 50 and rotatable with the crankshaft 50. The crankshaft 50 has a central axis, extending from one end of the crankshaft 50 to the other. The linear shaft 31 of the hand-operated lever 30 extends laterally and downwardly relative to the central axis of the crankshaft 50. The other end of the crankshaft 50 is connected to the crank 51, which extends radially and downwardly relative to the central axis of the crankshaft 50. 2025263798   05 Nov 2025

[371] The reverse motion linkage mechanism includes a fixed link 53 (a fixed rocking lever 53), and a first fixed pivot 63 connecting the fixed link 53 to a crosspiece 118 of the drafter chute 11 that extends between the left 112 and right sides 113 of the drafter chute body 11, perpendicularly of the centrally extending longitudinally axis 100. The fixed link 53 is capable of pivoting (rocking) about a vertical axis provided by the first fixed pivot 63.

[372] The reverse motion linkage mechanism includes a connecting rod 52, a first moving pivot 61 connecting the connecting rod 52 to the crank 51, and a second moving pivot 62 connecting the connecting rod 52 to the fixed link 53.

[373] As best seen in Figures 15 to 17, the reverse motion linkage mechanism includes a slider 54 (sliding pin 54) connected to the fixed link 53 distal to the first fixed pivot 63 and second moving pivot 62.

[374] The reverse motion linkage mechanism includes left and right slotted lever assemblies 55L, 55R, 56L, 56R, 57L, 57R each comprising a slot 550L, 550R at a first slotted end of each slotted lever assembly 55L, 55R, 56L, 56R, 57L, 57R, and each comprising a lever assembly 55L, 55R, 56L, 56R, 57L, 57R second end.

[375] The reverse motion linkage mechanism includes a sliding pivot 54, 550L, 550R comprising the slider 54 extending through each of the slots 550L, 550R such that the slider 54 is able to slide within the slots 550L, 550R. The slots 550L, 550R extend within spaced substantially horizontal planes.

[376] The reverse motion linkage mechanism includes third left and right moving pivots 67L, 67R connecting each lever assembly 55L, 55R, 56L, 56R, 57L, 57R second end to each gate-connecting lever 70L, 70R.

[377] With this construction and arrangement, when Position (II) is selected, the connecting rod 51 pulls the fixed link 53 such that the fixed link 53 pivots (rocks) in a first direction relative to its vertical axis, causing the slider 54 to pull on the left slotted lever assembly 55L, 56L, 57L and gate-connecting lever 70L to thereby open the left draft gate 2L. When Position (III) is selected, the connecting rod 51 pushes the fixed link 53 such that the fixed link 53 pivots (rocks) in a second direction relative to its vertical axis, causing the slider 54 to pull on the right slotted lever assembly 55R, 56R, 57R and gate-connecting lever 70R to thereby open the right draft gate 2R.

[378] The fixed lever 53 includes a central region 533, and first 530, second 531 and third arms 532 extending radially and outwardly from the central region 533 in a general Y-shape when viewed in plan. The second moving pivot 62 is located at the central region 533, the slider 54 is located at a second end region of the first arm 530, and, the first fixed pivot 63 is located intermediate the slider 54 and the second moving pivot 62.

[379] In Position (I) the first arm 530 substantially aligns with the substantially centrally extending longitudinal axis 100 (seen in Figure 15), and in Positions (II) and (III) the first arm 530 is out of 2025263798   05 Nov 2025 substantial alignment with the substantially centrally extending longitudinal axis 100 (seen in Figures 16 and 17).

[380] The draft gate catches 59L, 59R are magnetic. The right magnetic draft gate catch 59R is connected to the second arm 531 of the fixed lever 53 and the left magnetic draft gate catch 59L is connected to the third arm of the fixed lever 532.

[381] The slotted lever assemblies 55L, 55R, 56L, 56R, 57L, 57R each comprise a tensioner 56L, 56R in the form of a turnbuckle 56L, 56R, located between the first slotted end and lever assembly second end of each slotted lever assembly 55L, 55R, 56L, 56R, 57L, 57R, such that a respective substantially linear axis extends through each of the slotted lever assemblies 55L, 55R, 56L, 56R, 57L, 57R.

[382] The draft gate return mechanism includes gas dampers / gas springs 58L, 58R, also known as gas struts 58L, 58R, each having a piston 580L, 580R and piston housing 581L, 581R (see Figures 16 and 17). The draft gate return mechanism includes moving pivots 66L, 66R connecting the piston 580L, 580R of each gas strut 58L, 58R to the first arm of the fixed lever 530 between the slider 54 and first fixed pivot 63, and moving pivots 65L, 65R further connecting the piston housings 581L, 581R to the gate-connecting levers 70L, 70R (see Figure 18 for the connection point).

[383] As seen in Figure 18, the linkage mechanism 5 further comprises second left and right fixed pivots 68L, 68R connecting each of the gate-connecting levers 70L, 70R to the flange 24L, 24R of a draft gate 2L, 2R for pivoting about the vertical axis or vertically extending shaft 22L, 22R (or shaft piece 22L, 22R) about which the draft gate 2L, 2R pivots. Each fixed pivot 68L, 68R includes a bushing 680L, 680R and threaded locking bolt 681L, 680R that screws to the flange 24L, 24R and enables the gateconnecting lever 70L, 70R to pivot / rotate relative to and independently of the draft gate 2L, 2R unless the lever-locking mechanism 7L, 7R is in the locked configuration.

[384] The lever-locking mechanisms (lock and release mechanisms) 7L, 7R each include a left or right locking pin 72L, 72R that in the locked position extend through coinciding openings in the gateconnecting lever 74L, 74R and the flange 24L, 24R of the draft gate 2L, 2R. Each locking pin 72L, 72R is spring-loaded and comprises a finger grip 71L, 71R. To unlock, the locking pin 72L, 72R is pulled out of engagement with the opening 74L, 74R.

[385] This lever locking mechanism (lock and release mechanism) 7L, 7R allows the operator to disengage the left draft gate 2L and / or right draft gate 2R from the gate-connecting levers 70L, 70R of the linkage mechanism 5, in which case the operator can swing either or both draft gates 2L, 2R outwardly or inwardly, independently of the hand-operated lever 30. These components form part of an actuator override capable of overriding the manually operated actuator 3 and enabling both draft gates 2L, 2R to be manually positioned relative to the drafter body 11.This actuator override enables :

[386] 1. an animal (or person) to move freely between the entry and three exits when the draft gates 2L, 2R have opened, moved or swung outwardly relative to the drafter body 11. 2025263798   05 Nov 2025

[387] 2. a person to walk through the drafter 10 from one side of the drafter 10 to the other - pushing a wheelbarrow, welder or other equipment that is wider than the entrance chute 4.

[388] 3. stock to walk between holding pens without having them walk all the way through a crush or laneway.

[389] 4. an operator to release an animal that may have somehow gotten stuck or fallen down within the drafter 10, and the draft gates 2L, 2R are unable to be swung inwards towards the animal to provide a clearance such that the animal can be released from within the drafter 10.

[390] Each slot 550L, 550R includes a first slot end and a second slot end, in Position (I) the slider 54 locates within the first slot end of slot 550L (see Figure 15), and in Position (II) the slider 54 locates only within the first slot end of slot 550R (see Figure 17).

[391] In Position (I) the first slot end of each slot 550L, 550R generally aligns with the substantially centrally extending longitudinal axis 100 (see Figure 15), and in Position (II) and Position (III) only one of the first slot ends generally aligns with the substantially centrally extending longitudinal axis 100 and only one of the second slot ends generally aligns with the substantially centrally extending longitudinal axis 100 (see Figures 16 and 17).

[392] In use, the entrance chute 4 of the animal handler 10 is positioned next to, for example, a crush, such that there is no gap for an animal to escape between the crush and the entrance chute 4. Both access doors 41L, 41R remain closed, as seen in Figure 1. The hand-operated lever 30 is initially in Position (I).

[393] The operator then decides through which exit 13, 14, 15 the animal is to exit before releasing the animal from the crush. The hand-operated lever 30 is then left Position (I), or moved from Position (I) to Position (II) or Position (III) prior to releasing the animal from the crush: Position (I) - rear exit 13 open (see Figures 1-8, 15 and 20 (a)); Position (II) - left side exit 14 open (see Figures 9, 10, 11, 16 and 20 (b)); or, Position (III) - right side exit 15 open (see Figures 12, 13, 17 and 20 (c)).

[394] When the animal is released from the crush, it follows the walkway 42 and enters the entry 12 into the interior 114 of the drafter chute body 11. Since there is only one exit 13, 14, 15, the animal takes that exit 13, 14, 15 into a fenced yard.

[395] When the hand-operated lever 30 is rotated upwardly (clockwise when viewed from the front end 110) from Position (I) of Figure 15 to Position (II) of Figure 16 to open the left side exit 14, the handoperated lever 30 rotates the crankshaft 50 together with the crank 51 in the clockwise direction, the connecting rod 52 is pulled towards the crankshaft 50, the first arm of the fixed lever 530 pivots out of alignment with the centrally extending longitudinal axis 100, the slider 54 pulls on the left slotted lever assembly 55L, 56L, 57L, the slider 54 merely slides within the slot 550R of the right slotted lever assembly 55R, 56R, 57R, the left slotted lever assembly 55L, 56L, 57L pulls on the gate-connecting lever 70L, the piston 580L of the left gas damper 58L extends whilst the piston 580R of the right gas 2025263798   05 Nov 2025 damper 58R retracts, thereby causing the left draft gate 2L to pivot into the interior 114 of the chute body 11 until it collides with the right side draft gate 2R (or rubber door stopper attached to that right side draft gate 2R). The magnetic catch 59L then sticks to the housing 6 to keep the draft gate 2L in the open position.

[396] In order to close the left side exit 14, the hand-operated lever 30 is rotated downwardly (anticlockwise when viewed from the front end 110) from Position (II) to Position (I). The hand-operated lever 30 rotates the crankshaft 50 together with the crank 51 in the anticlockwise direction, the connecting rod 52 is pushed away from the crankshaft 50, the first arm of the fixed lever 530 is made to pivot back into alignment with the centrally extending longitudinal axis 100, the magnetic gate catch 59L of the third arm of the fixed lever 532 pivots away from the crank 51 and releases the housing 6, the slider 54 merely slides within the slots 550L, 550R, the left 58L and right gas dampers 58R assist in returning the left slotted lever assembly 55L, 56L, 57L and the gate-connecting lever 70L to Position (I), thereby causing the left draft gate 2L to swing back to the closed position.

[397] When the hand-operated lever 30 is rotated downwardly (anticlockwise when viewed from the front end 110) from Position (I) of Figure 15 to Position (III) of Figure 17 to open the right side exit 15, the hand-operated lever 30 rotates the crankshaft 50 together with the crank 51 in the anticlockwise direction, the connecting rod 52 is pushed away from the crankshaft 50, the first arm of the fixed lever 530 pivots out of alignment with the centrally extending longitudinal axis 100, the slider 54 pulls on the right slotted lever assembly 55R, 56R, 57R, the slider 54 merely slides within the slot 550L of the left slotted lever assembly 55L, 56L, 57L, the right slotted lever assembly 55R, 56R, 57R pulls on the gateconnecting lever 70R, the piston 580R of the right gas damper 58R extends whilst the piston 580L of the left gas damper 58L retracts, thereby causing the right draft gate 2R to pivot into the interior 114 of the chute body 11 until it collides with the left side draft gate 2L (or rubber door stopper attached to that left side draft gate 2L). The magnetic catch 59R then sticks to the housing 6 to keep the draft gate 2R in the open position.

[398] In order to close the right side exit 15, the hand-operated lever 30 is rotated upwardly (clockwise when viewed from the front end 110) from Position (III) to Position (I). The hand-operated lever 30 rotates the crankshaft 50 together with the crank 51 in the clockwise direction, the connecting rod 52 is pulled towards the crankshaft 50, the first arm of the fixed lever 530 is made to pivot back into alignment with the centrally extending longitudinal axis 100, the magnetic gate catch 59R of the second arm of the fixed lever 531 pivots towards the crank 51 and releases the housing 6, the slider 54 merely slides within the slots 550L, 550R, the left 58L and right gas dampers 58R assist in returning the right slotted lever assembly 55R, 56R, 57R and the gate-connecting lever 70R to Position (I), thereby causing the right draft gate 2R to swing back to the closed position. 2025263798   05 Nov 2025

[399] The lever-locking mechanisms 7L, 7R, if manually unlocked by an operator, allow the draft gates 2L, 2R to be disconnected from other components of the linkage mechanism 5 and pivoted within the interior 114 of the drafter chute body 11 or externally of the drafter chute body 11 as desired. Alternatively, the draft gates 2L, 2R can be manually locked in the closed position by the operator using the gate locking mechanisms 25L, 25R, such that they are not responsive to the actuator 3.

[400] If access to the walkway 42 is required, or if the entry 12 to the drafter chute body 11 is to be blocked, then one or both access doors 41L, 41R can be opened, as seen in Figure 19.

[401] Advantages of the animal drafter 10 as exemplified include:

[402] 1. A single hand-operated lever is actuated to control both draft gates.

[403] 2. Quicker operation.

[404] 3. More natural ergonomic movement matched to logical human thought patterns of operators.

[405] 4. Easier operational understanding for less experienced staff.

[406] 5. Potentially fewer drafting errors due to having to let go of one lever / handle and reach for another under stressful conditions.

[407] 6. Ability to override the actuator / hand-operated lever and selectively release one or both draft gates such that they can be freely swung outwardly, thereby enabling stock to walk across the drafter 10 between yards, move equipment across the drafter 10 from one yard to another, or to release trapped or fallen animals from between the draft gates.

[408] Referring now to Figures 21 and 22, there is shown an animal drafter assembly (5-way animal drafter) for drafting livestock such as cattle and sheep. The assembly includes a first drafter 10-D1 and a second drafter 10-D2, with features almost identical to those of the earlier described drafter 10 embodiment.
