Abstract: A guide sprocket assembly for use in combination with a non-driven, rotating tail shaft. The guide sprocket assembly includes a lock plate assembly securely fixed to the tail shaft for rotation along with the tail shaft. The lock plate assembly includes an annular sprocket groove that receives an annular guide sprocket having a plurality of projecting teeth spaced along its outer circumference. The guide sprocket is retained within the annular sprocket groove by a sprocket retainer. The combination of the guide sprocket and sprocket retainer are freely rotatable within the annular sprocket groove relative to the lock plate assembly. The teeth of the guide sprocket engage a drive chain, and the guide sprocket can rotate either in the direction of rotation of the tail shaft or in an opposite direction to properly align the individual links of the drive chain with the teeth formed on the guide sprocket.

Abstract: A sling belt conveyor has a pair of individually tensioned cables (209, 224) with transverse slings (51) pivotally connected to the cables (209, 224) which support a low tension conveyor belt (61) without being connected thereto. The belt (61) extends beyond the path of the support cables (209, 224) and is tensioned independently of the latter.

Abstract: A horizontal seat suspension for a vehicle for isolating horizontal ride vibrations for low frequencies normally found in large tractors, or other off the road vehicles, a provision for adjusting the seat to a desired position, and also a provision for selectively locking or activating the horizontal suspension.

Abstract: A vehicle seat suspension for isolating vertical ride vibrations at low frequencies normally found in larger tractors or other vehicles, and to do this without penalty of large static deflection normally required to obtain similar isolation in the typical mass-spring damper isolation suspension system.
