Card Feed Chain

Record card feeding is effected by means of an endless chain in which the cards are clamped in position to avoid displacement.

Besides the normal chain members 1, the chain has specially designed chain members 2 and 3 at predetermined intervals. Each member 2 includes a seat extended in a direction toward the member 3 following it. A lobe of member 3, when on top of seat, serves as a clamp. This closes in the straight portion of the chain.

It opens when the members 2 and 3 move into the range of sprocket wheels 4 and 5. A card 8, inserted at point 6, is clamped in position and advanced. It is ejected at point 7. As members 2 and 3 are slightly inclined with respect to one another, chain tightener 9 is used to increase the clamping force.
