Description:

Quick adjust, with a spring-loaded link that shifts through a series of notches for size adjustment.

A well-preserved example has the manufacturer name stamped on the shank. Known examples conform to the form shown in an August 1889 "new product write-up" in IRON AGE, rather than the form in this patent.
