The features in the patent add refinements and alternative forms to the wrench in patent no. 858,892.
It adds a reversible ratchet feature to the connection between the handle and gear-driving shaft, a hole in the handle for a supplemental rod handle for extra leverage and a spring-latch to hold sockets in the head. The interchangeable sockets include a holder for screwdriver bits.
Produced as the "MOSS" AUTOMOBILE WRENCH.
