Abstract

In order to connect a toothed timing belt to a carrier in a typewriter or printer, it is necessary to have a rigid connection between the belt and the carrier. In order to accomplish such a rigid connection, a clamp needs to be provided to engage the timing belt. The drawing shows a carrier for supporting a selection motor and print element 10. Carrier 10 supports a toothed rack 12 such that the teeth of the timing belt 14 may mate with the teeth of the rack 12. In order to maintain belt 14 in rigid engagement with member 12, a clamp 16 having a handle 18 is pivotally attached by means of shoulder screw 20 to the carrier 10. Clamp 16 also has a leg 18 formed thereon generally perpendicular to the clamp structure.

Self-Aligning Belt Clamp Mechanism

In order to connect a toothed timing belt to a carrier in a typewriter or printer, it is necessary to have a rigid connection between the belt and the carrier. In order to accomplish such a rigid connection, a clamp needs to be provided to engage the timing belt. The drawing shows a carrier for supporting a selection motor and print element 10. Carrier 10 supports a toothed rack 12 such that the teeth of the timing belt 14 may mate with the teeth of the rack 12. In order to maintain belt 14 in rigid engagement with member 12, a clamp 16 having a handle 18 is pivotally attached by means of shoulder screw 20 to the carrier 10. Clamp 16 also has a leg 18 formed thereon generally perpendicular to the clamp structure.

The clamp 16 is also provided with a formed top clamping surface 24 for retaining belt 14 in engagement with rack member 12. Leg 22 is engageable with a deflection leaf spring 26. Leaf spring 26 is deflected by support arms 28, a part of the carrier 10. Thus, spring 26, acting to restore to its flat unstressed condition, will bias clamp 16 downward, forcing the belt 15 to be physically pushed into engagement with the teeth of rack 12 providing the rigid connection necessary. To disconnect the belt 14, a latch surface 30 is provided on the carrier such that latching arm 32 will engage latch surface 30 and maintain the clamp 16 in its raised and disengaging position. This device provides the necessary rigid connection bet...
