Dual Mode Stacker

The card stacker assembly shown is provided with loadcompensating elements which are selectively actuated to permit proper stacking of either of two types of cards. The cards may differ with respect to size, thickness, density, or weight.

A stacker plate 1 for receiving cards 2 is attached to a rod 3, which is free to move vertically in a reciprocable manner within an inner bushing 4. The inner bushing 4, in turn, is slidably positioned within a spring anchor 5. The spring anchor 5 is fixedly mounted to a support 6 which is part of the card processing machine in which the stacker is used. The inner bushing 4 has a groove 7 machined in its periphery. Mounted in engageable relation with the groove 7 is a lever 8 which is manually moved about a pivot stud 9 into or out of the groove 7. If the lever 8 is engaged with the groove 7, then the inner bushing 4 is retained in a fixed position with respect to the support 6. If the lever 8 is out of engagement with the groove 7, then the inner bushing 4 is free to move in a reciprocable manner within the spring anchor 5.

A normally contracted coil spring 10 is provided to support the stacker plate 1 and the rod 3. The upper extremity of the spring 10 is threaded onto the fixed spring anchor 5 and the lower extremity of the spring 10 is threaded onto a spring anchor 11 which is fixed on the lower threaded portion 12 of the rod 3 by a nut
13. Some of the coils of the spring 10 are also threaded onto a portion...
