Mosler Safe & Lock 1887 Time Lock

[Jack Sullivan]

I picked up this time lock on eBay this evening. It appears to be an example of the title time lock with a number of differences from the photos shown on pages 232 & 233 of American Genius. As can be seen in the attached pix, the door window cutout has the same pattern but lacks the through-door winding eyelets. It also lacks the damascening shown in the book. Otherwise it appears to be the same lock.

This lock was based on the design of Phineas King of Beard & Brother of St Louis. I am attaching screenshots of the 2 patents issued to King for this design. Beard & Borother sold their patent rights to Mosler in 1887.

I'm looking for information on the door key for this lock. The winding arbors look to take standard winding keys.

Any comments concerning this lock would be appreciated. Thanks!

Jack
