[0012] The following detailed description describes various features and functions of the disclosed apparatus, machines, and systems with reference to the accompanying figures. The illustrative apparatus, machines, and system embodiments described herein are not meant to be limiting. It will be readily understood that certain aspects of the disclosed apparatus,machines, and systems can be arranged and combined in a wide variety of different configurations, all of which are contemplated herein.

[0013] Figure 1 depicts a perspective view of a screen tensioning assembly 100, according to an example embodiment. The screen tensioning assembly 100 includes a threaded rod 102 having a portion 102A, a hub 104 defining a through bore 104A, a plurality of support arms 106 having a first end 106A and a second end 106B, first and second securing members 108 and 109, a screen 110 having a first side 112 and a second side (not shown) opposite the first side, a support ring 130, and a tensioner 120. The tensioner 120 includes a plate 124 and a driver 122 including a push rod 126.

[0014] The through bore 104A may extend along a longitudinal axis of the hub 104. The through bore 104 A may be centrally disposed on the hub 104 such that a perimeter of the through bore 104 A may be concentric with an outer perimeter of the hub 104. The threaded rod 102 may be coupled to the hub 104 and disposed within the through bore 104 A. In some examples the hub 104 may be fixed on the threaded rod 102. For example, the hub 104 may be fixed to a position on the threaded rod 102 using a fastener, such as the first securing member 108, and / or welded to the threaded rod 102. The first securing member 108 may be a coupling nut, for example. However in other examples, the first securing member 108 may be another fastener, such as a hex nut or lock nut. The second securing member 109 may be similar to the first securing member 108. In some examples, the through bore 104A may be threaded, where at least one of the threads engages with at least one thread on the threaded rod 102. However, in other examples the through bore 104A may be unthreaded.

[0015] The plurality of support arms 106 may be coupled to the hub 104. For example, the first end 106A of each of the plurality of support arms 106 may be coupled to the hub 104. such as each of the first ends 106A may be disposed within a circular aperture defined about a radial perimeter of the hub 104. The plurality of support arms 106 may protrude radiallyoutward from the hub 104. The second end 106B of each of the plurality of support arms 106 may be coupled to the support ring 130, such as coupled to an inner surface of the support ring 130.

[0016] In some examples, the screen 110 is coupled to the support ring 130. The screen 110 may be disposed within the support ring 130 such that the support ring 130 is disposed about an outer perimeter of the screen 110. A center point of the screen 110 may be aligned with the threaded rod 102. For example, a longitudinal axis defined by the threaded rod 102 may be aligned with the center point of the screen 110. The first side 112 of the screen 110 may be disposed proximal (e.g., facing towards) to the hub 104 and the second side (not shown) may be disposed distal (e.g., facing away) to the hub 104.

[0017] The tensioner 120 may include the plate 124 and the driver 122 that includes the push rod 126. The tensioner 120 may adjustably control a tension state in the screen 110. For example, actuation of the driver 122 may cause one or more components of the tensioner 120 to increase and / or decrease the tension state of the screen 110. In other examples, however, another tensioner may be used to adjust the tension state in the screen.

[0018] The plate 124 may have a first surface and a second surface. As shown, the first surface of the plate 124 may be in contact w ith and / or coupled to the first side 112 of the screen 110. A first end 126A of the push rod 126 may be coupled to the second surface of the plate 124. A second end 126B of the push rod 126 may be coupled to the threaded rod 102. One or more fasteners may be used to secure the push rod 126 to the threaded rod 102. For example, the second securing member 109 may be used to adjustably fix and / or lock a position of the push rod 126 on the threaded rod 102.

[0019] In the example shown, the driver 122 includes the push rod 126. Actuation of the driver 122. such as rotation of the push rod 126 in a clockwise and / or counterclockwise direction, may cause a change of distance or displacement between the plate 124 relative tothe hub 104. For example, actuation of the driver 122, through rotation of the push rod 126, may translate the push rod 126 along the threaded rod 102 such that in a first actuation direction (e.g., clockwise) the plate 124 may be driven away from the hub 104 and in a second actuation direction (e.g., counterclockwise) the plate 124 may be driven towards the hub 104. In some examples, rotation of the push rod 126 may increase and / or decrease a length of the portion 102A of threaded rod 102. Once a desired tension state of the screen 110 is reached, the second securing member 109 may be engaged with the push rod 126 to temporarily secure the position of the push rod 126 on the threaded rod 102. In some examples, the driver 122 is the push rod 126. The push rod 126 may include an internally threaded sleeve (e.g., a threaded aperture) extending at least a portion of a length of the push rod 126. The threaded sleeve of the push rod 126 may be engaged with one or more threads of the threaded rod 102 such that actuation (e.g., rotation) of the push rod 126 may translate the push rod 126 along the threaded rod 102 to increase or decrease a displacement of the plate 124 relative to the hub 104. While the threaded rod 102 is described as including threads, in some examples a rod may be unthreaded, such as a smooth rod. Thus, in some examples the rod 102 may be any suitable rod.

[0020] By increased and / or decreasing a distance between the plate 124 and the hub 104 an amount of tension in the screen 110 may be adjusted. For example, increasing actuation of the driver 122, such as rotation of the push rod 126, in the first direction to drive the plate 124 away from the hub 104 may increase an amount of tension of the screen 110. Whereas, actuation of the driver 122 in the second direction to drive the plate 124 towards the hub 104 may decrease an amount of tension on the screen.

[0021] In some examples, the screen tensioning assembly 100 may be used to adjust an amount of tension on the screen 110 prior to installation in a machine, such as the machine 10 described below. Adjusting an amount of tension in the screen 110 prior to installation in themachine may reduce an occurrence of screen damage, such as tearing, compared to adjusting screen tension after installation in the machine.

[0022] Figures 2A and 2B depict perspective views of another screen tensioning assembly 200, according to an example embodiment. The screen tensioning assembly 200 includes a threaded rod 202 having a first portion 202A and a second portion 202B; a hub 204 defining a through bore 204A; a plurality of support arms 206 having a first end 206A and a second end 206B; first and second securing members 208 and 209; a screen 210 having a first side 212, a second side 214 opposite the first side, and a centrally located aperture 216; a support ring 230; and a tensioner 220. The tensioner 220 includes a driver 222, a plate 224, and the second securing member 209.

[0023] One or more components of the screen tensioning assembly 200 may be the same as or similar to the screen tensioning assembly 100. For example, the threaded rod 202, the hub 204, the through bore 204A, the plurality of support arms 206 having first and second ends 206A, 206B, the first securing member 208, and / or the support ring 230 may be similar to those described in the screen tensioning assembly 100 and will not be repeated. Further, one or more aspects described with the screen tensioning assembly 100 may be combinable with the screen tensioning assembly 200.

[0024] In some examples, the screen 210 is coupled to the support ring 230. The screen 210 may be disposed within the support ring 230 such that the support ring 230 is disposed about an outer perimeter of the screen 210. The screen 210 may include one or more apertures. For example, the screen 210 may include the centrally located aperture 216. The threaded rod 202 may be disposed in the centrally located aperture 216. The threaded rod 202 may extend from the first side 212 to the second side 214 of the screen 210 through the centrally located aperture 216 such that a first portion 202A of the threaded rod 202 is on the first side 212 and a second portion 202B is on the second side 214. In such examples, the first side 212 of thescreen 210 may be disposed proximal (e.g., facing towards) to the hub 204 and the second side 214 may be disposed distal (e.g., facing away) to the hub 204.

[0025] The tensioner 220 may include the driver 222, the plate 224, and the second securing member 209. Similar to the tensioner 120, the tensioner 220 may adjustably control a tension state in the screen 210. For example, actuation of the driver 222 may cause one or more components of the tensioner 220 to increase and / or decrease the tension state of the screen 210. In other examples, however, another tensioner may be used to adjust the tension state in the screen.

[0026] The plate 224 may be disposed on the threaded rod 202. The plate 224 may have a first and second surface. In some examples, the first surface of the plate 224 may be engaged with and / or coupled to the first side 212 of the screen 210 and the second surface of the plate 224 may be engaged with and / or coupled to the driver 222. The plate 224 may include an aperture. The aperture may be centrally located on the plate 224 and configured to receive the threaded rod 202 and / or the driver 222. For example, the driver 222 may extend through the plate 224 and the screen 210 and couple to the second surface of the plate 224. While the plate 224 shown has a circular profile, in other examples the plate 224 may have a rectangular, polygonal, oblong, ovular, triangular, or arcuate profile. In operation, as the driver 222 is actuated, the plate 224 may engage with the screen 210 to increase or decrease a state of tension in the screen 210.

[0027] The driver 222 may be coupled on the threaded rod 202. In some examples, the driver 222 may be disposed within the centrally located aperture 216 and extend through the screen 210 such that the driver 222 may be disposed on the first and second sides 212. 214 of the screen 210. Thus, the driver 222 may be disposed along the first and second portions 202A, 202B of the threaded rod 202. The driver 222 may include a first portion 222A and a second portion 222B. The first portion 222A of the driver 222 may be coupled to the plate 224 andthe second portion 222B of the driver 222 may extend through the centrally located aperture216 to the second side 214 of the screen 210. In some examples, actuation of the second portion 222B of the driver 222 may adjustably control a tension state of the screen 210. For example, actuation of the second portion 222B may translate the screen 210 along the threaded rod 202 such that in a first actuation direction the screen 210 may be driven away from the hub 204 and in a second actuation direction the screen 210 may be driven towards the hub. The first actuation direction may increase the tension state, such as increasing an amount of tension, of the screen 210 as the plate 224 is driven away from the hub 204. The second actuation direction may decrease the tension state, such as decreasing the amount of tension, of the screen 210 as the plate 224 is driven towards the hub 204.

[0028] In some examples, actuation of driver 222, such as rotation of the driver 222 may occur in a clockwise and / or counterclockwise direction. Rotation of the driver in either the clockwise and / or counterclockwise direction may cause a change of distance or displacement between the plate 224 relative to the hub 204. For example, actuation of the driver 222 may engage the plate 224 with the screen 210 as the plate 224 and the driver 222 translate along the threaded rod 202. In the first actuation direction the plate 224 and / or the driver 222 may be driven away from the hub 204 and in the second actuation direction the plate 224 and / or the driver 222 may be driven towards the hub 204. Once a desired tension state of the screen 210 has been reached, the second securing member 209 may be engaged with the driver 222to temporarily secure the location of the plate 124 and / or driver 222 relative to the hub 204.

[0029] In some example, the driver 222 may include a threaded sleeve. One or more threads of the driver 222 may be configured to engage with one or more threads of the threaded rod 202. Engagement of the one or more threads of the threaded sleeve with the one or more threads of the threaded rod 202 may translate the threaded sleeve along the threaded rod 202during actuation (e.g., rotation). While a threaded sleeve is shown as the second portion 222B of the driver 222, in other examples another type of driver may be used, such as a hex nut.

[0030] The screen tensioning assembly 200 may allow for tensioning of the screen 210 to occur prior to installation in a machine or an apparatus. Adjustably controlling the tension state of the screen 210 prior to installation in the machine may decrease an amount of installation time required and / or decrease a likelihood of the screen becoming damaged compared to tensioning of the screen 210 after being installed in the machine.

[0031] Figures 3A and 3B depict perspective views of another screen tensioning assembly 300, according to an example embodiment. The screen tensioning assembly 300 includes a threaded rod 302 having a first portion 302A and a second portion 302B; a hub 304 defining a through bore 304A; a plurality of support arms 306 having a first end 306A and a second end 306B; first and second securing members 308 and 309; a screen 310 having a first side 312, a second side 314 opposite the first side, and a centrally located aperture 316; a support ring 330; and a tensioner 320. The tensioner 320 includes a driver 322 and a plate 324.

[0032] One or more components of the screen tensioning assembly 300 may be the same as and / or similar to the screen tensioning assembly 100 and or 200. For example, the threaded rod 302, the hub 304, the through bore 304A, the plurality of support arms 306 having first and second ends 306 A, 306B, the first and second securing members 308 and 309, the screen 310 having first and second sides 312, 314 and the centrally located aperture 316, and / or the support ring 330 may be similar to those described in the screen tensioning assembly 100 and / or 200 and will not be repeated. Further, one or more aspects described with the screen tensioning assembly 100 and / or 200 may be combinable with the screen tensioning assembly300.

[0033] The tensioner 320 includes the driver 322 and the plate 324. Similar to the tensioner120 and / or 220, the tensioner 320 may adjustably control a tension state in the screen 310. For example, actuation of the driver 322 may cause one or more components of the tensioner 320 to increase and / or decrease the tension state of the screen 310. In other examples, however, another tensioner may be used to adjust the tension state in the screen.

[0034] The plate 324 may be disposed on the threaded rod 302. The plate 324 may have a first and second surface. In some examples, the first surface of the plate 324 may be engaged with and / or coupled to the second side 314 of the screen 310 and the second surface of the plate 324 may be engaged with and / or coupled to the driver 322. The plate 324 may be similar to the plate 224 described above. For example, the plate 324 may include an aperture configured to receive the threaded rod 302 such that the plate 324 is disposed on the second portion 302B of the threaded rod 302 between the driver 322 and the second side 314 of the screen 310. In operation, as the driver 322 is actuated, the plate 324 may engage with the second side 314 of the screen 310 to increase or decrease a state of tension in the screen 310.

[0035] The driver 322 may be coupled the threaded rod 302, such as on the second portion 302B proximal to the second side 314 of the screen 310. Thus, the driver 322 may be disposed on the second side 314 of the screen 310. Actuation of the driver 322, such as rotation of the driver 322 in a clockwise and / or counterclockwise direction, may cause translation of the driver 322 and / or the plate 324 along the threaded rod 302. In some examples, actuation of the driver 322 may adjustably control a tension state of the screen 310 by translating at least a portion of the screen along the threaded rod 302. In a first actuation direction the driver 322, the plate 324. and / or the portion of the screen 310 may be driven towards the hub 304 to increase the tension state of the screen 310. In a second actuation direction the driver 322, the plate 324. and / or the portion of the screen 310 may be driven away from the hub 304 which may decrease the tension state of the screen 310.

[0036] For example, as the driver 322 pushes the plate 324 towards the hub 304 the plurality of support arms 306 may resist (e.g.. push back) movement of the outer portion of the screen 310 coupled to the support ring 330. Thus, an inner portion of the screen 310 may deflect due to forces from the plate 324 as the plate 324 is driven towards the hub 304, while the outer portion of the screen 310 may resist deflection due to the plurality of support arms 306 coupled to the hub 304 which may be fixed onto the threaded rod 302. The amount of deflection of a portion of the screen 310 coupled with resisting forces by the plurality of support arms 306 may allow for the tension state in the screen 310 to be increased and / or decreased based on a position of the plate 324 and / or the driver 322 relative to the hub 304. While the driver 322 shown may include one or more hex nuts, in other examples another driver may be used, such as a sleeve nut.

[0037] The screen tensioning assembly 300 may allow for tensioning of the screen 310 to occur prior to installation in a machine or an apparatus. Adjustably controlling the tension state of the screen 310 prior to installation in the machine may decrease an amount of installation time required and / or decrease a likelihood of the screen becoming damaged compared to tensioning of the screen 310 after being installed in the machine.

[0038] Figure 4 depicts a machine 10, according to an example embodiment. The machine 10 includes the screen tensioning assembly 100 and a frame 12. While the machine 10 includes the screen tensioning assembly 100, in other examples the screen tensioning assembly 200 or 300 may be used. In further examples, the screen tensioning assembly included in the machine 10 may be a combination of one or more components of the screen tensioning assembly 100, 200. and / or 300. In some examples, the machine 10 may be a vibratory screener.
