Abstract: A chain driven by two sprockets spaced a short distance apart along their common axial centerline. The chain includes elongated pins that extend beyond the outer surfaces of the chain link plates, on both sides, by a distance about equal to the width of the spaced apart sprockets. The chain is aligned midway between the sprockets, and the sprocket teeth drive on the extended portion of the chain pins. Where a flight is attached to the chain links, the pins are extended still further, to fit into the indentations or holes in the flights. This provides an exposed length of each pin in alignment with the sprocket on each side for driving purposes. The chain has a piece extending between the plates to reduce the likelihood of a pin extending further outside of one side plate or the other. A shoulder on the pin further reduces the likelihood of this happening.

Abstract: A positioning system utilizes a shot pin to fix the position of a grooved pallet at stations in a production line. The pallet travels along the production line under the influence of advancing feed pins. When the pallet arrives at a station, the head of the shot pin is positively urged toward the groove in the pallet until the head locks the pallet in the desired position. Simultaneously, the feed pin disengages from the pallet. When work is completed at the manufacturing station, the head of the shot pin moves away from and releases the pallet. Simultaneously, the feed pin engages the pallet. The feed pins and the shot pin operate in tandem, by moving in-phase along parallel lines in the same direction to accomplish their individual functions. The feed pins and the shot pin can operate relatively quickly without applying unnecessary torque to the conveyor or the pallet.
