Feed Hopper and Presser

A feed hopper 1 is provided with a presser unit 2 which operates semiautomatically and which exerts a practically constant pressure on a stack of cards or tickets 3 during feeding operations.

A vacuum drum 4, which rotates in the direction indicated by the arrow, removes tickets 3 successively from the bottom of the stack.

The pressure unit 2 has a pair of sliders 5 and 6, each of which fits inside an associated channel 7 and 8. Springs 9 and 10 are fixed inside the channels 7 and 8 at points 11 and 12 and are respectively attached to the sliders 5 and 6, to exert a downward pull on the presser unit 2.

The downward pull of springs 9 and 10 is transferred to the stack 3 by means of a presser 13 which projects into the hopper during feeding operations. The presser 13 has a formed extension 14 which is free to slide in a complementary channel 15 which is provided in the presser unit 2. A spring 16 fixed to the presser unit 2 at 17 and to the presser 13 at 18 exerts a continuing pressure which tends to pull the presser 13 out of the hopper. :AB An 1 slot 19 is provided in the hopper side plate 20. The presser 13 is removed from or inserted in the hopper only through the upper part of the 1 slot at 21 or through the lower part of the 1 slot at 22.

A normal sequence of operations is shown in the small drawings A, B, C and
D. In A, the presser unit 2 has been manually raised to the top of the hopper 1 with the presser 13 restored against a stop 2...
