A ball transfer device is disclosed herein. An embodiment of the ball transfer device includes a chamber, wherein a first opening and a second opening extend into the chamber. A ball is located between the first opening and the second opening and is movable within the chamber. The movement extends between a first position and as second position, wherein a portion of the ball is movable into the first opening when the ball is in the first position.

Ball transfer device

Apparatus wherein an endless moving conveyor belt is trained around two spaced apart shafts and wherein at least one of the shafts is mounted in a bearing that is resiliently urged in a direction away from the other shaft to provide the proper tension in the endless moving conveyor belt, and shock absorbing apparatus is provided for absorbing excessive forces placed on the bearing with or without the resilient urging of the bearing.

Tension controlling and shock absorbing apparatus for an endless conveyor

Apparatus for supporting the guide members for guiding the moving endless chain for moving an endless belt conveyor, and in particular an endless conveyor for a power turn, mounted on a support frame wherein the guide members are mounted on a support member and at least one isolation member comprising a resilient sound and vibration deadening material is provided and the support member and support frame are secured together with the at least one isolation member located therebetween so as to isolate the support member from the support frame.

Chain guide mounting apparatus

A wheel and track system wherein the track comprises a base and a pair of spaced apart upstanding sides is provided for guiding movement of a vehicle having four wheels over a controlled path and at least two of the wheels are mounted for rolling movement over the base and between the spaced apart upstanding sides and wherein a scuff plate is provided between the two wheels and the upstanding sides of the track so that there can be relative rotational movement between the scuff plates and the wheel and relative movement between the scuff plates and the upstanding sides of the track in the event of contact between the scuff plates and the upstanding sides of the track so as to minimize any tendency for the wheel to ride up the upstanding side and also to protect the upstanding side and the wheel from damage.
