Copier Hand Crank

When servicing a xerographic copier it is often necessary to work from the front of the copier, and to manually move the copier's components, such as the photoconductor drum, while observing the various copier apparatus and/or making adjustments thereto.

The copier's main drive motor 10 includes a gear 11 which is connected by belt 12 to supply motive power to the copier's various movable members, including a photoconductor drum, not shown. Gear 11 is driven clockwise (viewed from the front of the copier) when motor 10 is energized. This motor is located to the back of the copier and thus may be within a few inches of an adjacent wall. Gear 13 is connected to shaft 14 through a one-way safety clutch
15. Shaft 14 is carried by mounts 16 and extends to the front of the copier. The shaft is biased to the front on the copier by spring 17, such that gears 11 and 13 normally do not engage.

When it is desired to manually move the copier's mechanical components, hand crank 18 is placed on the mating pin carried by the forward end of shaft 14, the shaft is pushed to the rear, whereupon the gears 11, 13 engage. The drive motor 10 can now be manually moved clockwise as the manual crank 18 is rotated counterclockwise.

In the event that the drive motor 10 is inadvertently energized with the gears 11, 13 engaged, clutch 15 allows gear 13 to freely turn counterclockwise on shaft 14, thus preventing possible injury.
