You can find it using the patent date. The Official Gazette of the United States Patent Office has been digitized and is available on-line. Start by just Googling "Patent July 4, 1924" and go from here. I imagine that this is one piece of a larger device / mechanism.

Sorry. Make that "Patent July 8, 1924."

Remember to do Google image search, too, as the patent drawings often show up that way.
