Embodiment Construction

[0059] exist figure 1 In , a power unit 20 is shown which is releasably coupled to any one of a number of accessories for driving purposes, three of these accessories are indicated at 16, 14 and 17, respectively a water pump, a generator and In the form of a high pressure pump.

[0060] The power unit 20 is in the form of a single-cylinder gasoline engine 21 molded in a tube frame 15 provided with a pair of wheels 22 to facilitate transport and with a handle 23 secured by screws 24 which can Folds from the upright position shown to a horizontal position for more compact storage. The frame 21 is also provided at its front end with a U-shaped sub-frame 25 which carries two spaced apart sleeves 26 and which can be moved from the horizontal position shown by suitably releasing and locking the two handles 27. Articulated to an upright compact storage / transport position, with a handle on each side of the front portion of the frame 21 , while manually operable braking mechanisms 28...

Abstract

A power take off coupling for connecting an engine (20, 21) to a site accessory (16, 14, 17), comprises a resilient power transmission component (3) within the coupling; a latching device (8, 46, 9) to mechanically latch the accessory to the engine (20, 21), with a manually operable release handle (13) to effect unlatching. A power output shaft of the engine (20, 21) carries one half (5) of a dog clutch with the other half (7) carried by the accessory (16, 14, 17).; An alignment arrangement comprises a first annulus ring (18) attached coaxiaily to an output shaft assembly of the engine (20, 21 ), and a second annulus ring (19) attached coaxiaily to an input shaft assembly of the accessory, with the two rings (18, 19) being of different diameters, such that one ring is adapted to be engaged coaxiaily within the other ring with close tolerances, such that the external periphery of the smaller ring (18) engages at least parts of the internal periphery of the larger ring (19) to provide for accurate coaxial alignment of the power output shaft of the engine (20, 21) and the power input shaft of the accessory.; The invention also includes a dog clutch coupling, with one dog clutch half (5) biased by springs (4), such that should the dog clutch teeth initially foul one another, rather than mesh, the dog clutch half (5) retracts to permit meshing, and then advances.

Description

technical field [0001] The present invention relates to a power take-off coupling for use with portable power units, typically for field use, such as new construction, refurbishment and the like. Background technique [0002] A range of field equipment attachments—such as water pumps, air compressors, generators, power washers, vibrating stirrers, chippers, pulverizers, vacuum units, plate compactors, etc.—require a power transmission that The device is conventionally powered by a portable power unit in the form of a single cylinder multipurpose engine. The current process requires leasing or purchasing various facility or equipment attachments, each of which is provided with its own multi-function motor, which is usually the most expensive component of the attachment. Accordingly, purchasing, safely storing and maintaining large quantities of these accessories can place a financial, logistical and time burden on their owners. [0003] Typically, the average builder may pu...
