(under subclass 1.17) Devices consisting of a single lever.
(1) Note. This subclass is made up primarily of patents wherein the device is a single rigid element. Plural element devices are also included, however, when the relative movement of the parts occurs merely (1) for the purpose of moving the lever elements to change the overall dimensions subsequent to the initial operation of the device in the manner of a lever or pry, or (2) for purposes other than tire setting or removal (e.g., stowage).
