Patent for a new and improved trace-carrier. This design "is to provide the trace-carrier with a locking-brace, which is held in a closed position by the chain, which prevents all possibility of the chain from becoming detached from the carrier while in use" (lines 16-20). To this end, it consists, "with the body having a strap-fastener and an outwardly and upwardly extending hook, of a locking-plate, which is hinged at its upper end to the upper portion of the body, and its lower end provided with an inner perforated projection through which the said hook passes, and a shorter projection" (lines 78-85).
