Abstract

In a hopper having a large capacity, the weight of documents may impair the effective operation of the document picking mechanism, not shown, located adjacent the lowermost document. To effectively reduce the force exerted at the bottom of the document stack 2 within hopper 3, lever 4 provides a projecting end portion 5 which can be adjusted to project into the hopper to divide the stack. By carrying a portion of the load exerted by the weight of the document stack, the lever effectively reduces the force exerted on the picker mechanism. While diminishing the effective load on the picker mechanism by metering cards past the projection 5, such projection forms an obstruction when it is necessary to remove the documents from the hopper.

In a hopper having a large capacity, the weight of documents may impair the effective operation of the document picking mechanism, not shown, located adjacent the lowermost document. To effectively reduce the force exerted at the bottom of the document stack 2 within hopper 3, lever 4 provides a projecting end portion 5 which can be adjusted to project into the hopper to divide the stack.

By carrying a portion of the load exerted by the weight of the document stack, the lever effectively reduces the force exerted on the picker mechanism. While diminishing the effective load on the picker mechanism by metering cards past the projection 5, such projection forms an obstruction when it is necessary to remove the documents from the hopper.

Lever 4 provides projection 5 which extends through an opening in the hopper wall 7. The center of gravity of lever 4 is disposed to cause pivoting to the position shown at B, when unconstrained. When in the operative position, lever 4 is restrained by lever 8 with the force exerted by the surface of tab 9 against the edge surface 10 of the lower portion of lever 8 directed through the axis of pivot pin 11. Projection 12 on lever 8 limits clockwise rotation thereof while projection 13 on lever 4 precludes counterclockwise rotation beyond the lower end portion of lever 8.

The lever 4 is pivoted to the operative condition shown at A by pressing toward upper wall 7 on projection 15 (or below the axis of pivot pin...
