Type Sector Endorser

This rotatable endorser provides an inexpensive, simple, light weight and low-inertia unit, suitable for providing endorsement printing on documents at high speed. The design is such that the date number, which must be changed daily, and the endorsement plate sector, which is changed at longer intervals, can be readily changed by a machine operator without the need for tools.

The sector carrier has two oppositely disposed endorser plate holding or carrier portions indicated generally at 1 and 3, having a common hub portion 5, which mounts on the tapered end of the endorser drive shaft 7. The endorser carrier can be retained on the shaft by a suitable nut, not shown, screwed onto the threaded end of shaft 7. Each of the two endorser printing plates 9 and 13 are mounted on holders 15 and 17, which are provided with a tapered dovetail base which is engaged by a corresponding portion of the sector carrier. When fully engaged, retaining springs 19 and 21 will hold the plates in their proper position.

The date plugs such as 23, are conical and are retained in a conical socket in the holders such as 17. A projection or boss 25 on the date pin not only aids in the insertion and removal of the date pin, but also insures that the numerals on the end will be properly aligned. In the drawing, the holder 15 is shown fully engaged with its carrier, while the holder 17 is shown partially withdrawn, and with its date plug 23 withdrawn.
