Abstract: A ring dispenser comprising a rotating rod having an acme thread along one portion thereof and a helical coil spring at a dispensing end thereof feeds individual rings to a ring transfer device located at the dispensing end of the rod. The rod is rotated by a motor and the rings are automatically separated and directed to the end of the rod where a sensor detects the presence of the ring and stops the motor. When the ring transfer device is ready to pick up a ring, the motor starts again and a ring slides off a conical tip of the rod onto the transfer device by rotation of the rod. The rings have diameters greater than the separation between the individual threads of the rod so that the rings move on the crests of the threads and are out of engagement with the thread roots. The spacings between the convolutions of the coil spring are greater than the thickness of the rings so that the rings move on the rod surface as the rings approach the dispensing end of the rod.

Abstract: A means and method for applying innerliner material to a tire building drum and more particularly to a means and method for cutting and applying the innerliner material and further allowing for stock width measurement and precise centering without the possible edge distortion of known guiding systems.

Abstract: An improved vehicle suspension system for use on axles of trailers, trucks, and the like. A pair of wheels are individually rotatably mounted on stub axles attached to a pair of trailing arms which are connected to and extend radially rearwardly from a pair of pivot sleeves. The sleeves are pivotally mounted on brackets connected to the vehicle frame. A pair of spaced levers are attached to and extend radially outwardly from each of the pivot sleeves and rotate in unison with the trailing arms. An annular elastomer spring is located between a pair of metal end plates which are pivotally mounted on and located between the spaced levers. One of the end plates is connected to the lever by a hollow shaft and another shaft is connected to the other end plate and extends through the elastomer spring and into the hollow shaft to maintain the spring in axial alignment.
