Abstract: 299,685. Suczek, R. May 18, 1928. No Patent granted (Sealing fee not paid). Cylinder machines; hopper-and-plunger machines; delivery.-Compressed food or medicine tablets are made in long rolls of adherent units capable of ready separation into individual units, by the process of charging a chamber with the food, moving the position of the chamber and subjecting the charge to initial compression, and again moving the chamber and ejecting the material therefrom to receive its final compression after ejection through a series of repeated strokes. For example, rough grains or cereals are delivered from the hopper 20 by the measuring wheel 38 to the funnel 34, which is revolved slowly by worm gear 37, and thence deposited in the mould 27. Centres or cores, such as raisins, at the same time are delivered from the hopper 21 through the spring-mounted reciprocating funnel 40. The mould carrier is rotated step-by-step by ratchet mechanism 56, and the material undergoes a preliminary compression by the ram- 75 and a final one by the ram 16<a> which forces it against previously formed tablets in the delivery tube 29. The ram 16<a> has an offset end to enter the open side of the mould drum 25 and is driven by an eccentric 14. On each compressing stroke it also operates the ram 75 to compress the next batch of material. The cam 13 drives the ratchet mechanism 56 through the rod 55 and also reciprocates the funnel 40 through the links 54, 45.
