Relates to; "Certain Improvements in Chronometers, Watches, and other Timekeepers". The patent describes an escapement which Philcox names the "diamond lever" consisting of the, "novel arrangement, constuction, and adaptation of peculiarly formed levers or impelling and detant pieces by means of which I construct a more simple and less expensive escapement than those in present use."
