ABSTRACT:
A mechanical feeding mechanism for delivering plugs seriatum from a cylindrical delivery chute having upper and lower latching mechanisms. Each of the upper and lower latching mechanisms are movable from a latching position wherein the latching mechanism engages a plug in the chute and an unlatching position. Linkage mechanism connects the upper and lower latching mechanisms such that when one of the latching mechanisms is in the unlatching position the other latching mechanism is biased toward the latching position. Restraining mechanism engages a plug resting on the lower latching mechanism restraining the plug against rotational movement when the lower latching mechanism is in the latching position thereof, and actuating mechanism moves the lower latching mechanism from the latching position to the unlatching position thereby allowing a first plug to be dispensed from the chute while simultaneously moving the upper latching mechanism toward the latching position to engage a plug and prevent it from travelling through the chute until the first plug has been dispensed.
