Description:
The adjustable bicycle wrench serves as the pump handle for the tire pump. The body of the pump has a catch to hold the wrench substantially within the pump body to make a compact pocket tool. The movable jaw can be completely removed, and has a screwdriver on the end of the movable jaw shaft.

A "new old stock" example in its original box provides an alternate manufacturer name and an example of how the tool was marketed.

The patent date on the tool (May 23, 1893) is an earlier Dodge patent (no. 498,051).
