Abstract
A hold down mechanism includes a shaft, ring-shaped member, latch device fixed to the member and latchable with teeth thereon to permit unassisted movement of the member and latch device downward along the shaft due to the influence of gravity on the member but not upwardly along the shaft by manually lifting the member without unlatching the latch device from the shaft, support arms fixedly spaced apart on and extending inwardly from the member, platens independently reciprocally mounted below support arms, and a spring mounted between platens and support arms exerting a weak downward force on platens independently so as to bias platens to move downwardly away from support arms and against items in stacks aligned under platens while at the same time yieldable to permit platens to move upwardly toward support arms to accommodate differences in stack heights as items are successively dispensed therefrom. Optionally, the mechanism may be used without the shaft.
