THERON I. SMITH, OF NORTH ATTLEBOROUGH, MASSACHUSETTS.
SPECIFICATION forming part of Letters Patent No. 247,701, dated September 27, 1881,
Application filed July 28, 1881. (No model.)
To all whom it may concern Be it known. that I, THERoN I. SMITH, of North Attleborough, in the county of Bristol and State ot' Massachusetts, have invented a new and useful I mprovementin Bracelets; and I do hereby declare that the following is a full, clear, and exact description ofthe same.
Myinvention relates to bracelets of that class in which a spring is used to throw the bracelet open, and also in that class in which the wings ofthe bracelet overlap.
A bracelet composed of parts hinged together and having a. spring adapted to throw the parts open is described in English provisional specification No. 762 of 1866, and bracelets with overlapping wings are in common use and well known.
My invention consists in combining with the overlapping'wings a hook and eye ot any suitable form, adapted to connect the two wings and to be held together in connection by means of the tension of a spring.
In the drawings, Figure 1 represents the bracelet embodying aform of hook which l have deemed suitable for the purpose, said bracelet being shown in side elevation. Fig. 2 shows the bracelet in the same position open. Fig. 3 is a separate view of the overlapping ends, partly in section, showing the form of hook and eye.
In the drawings, the two wings ot' the bracelet are marked A and B. They are jointed y at a, the joint being of any suitable construction, and are provided with a spring adapted to throw the parts open when the catch is not in contact. The spring may he of plain watchspring form, or of any suitable construction.
In the form shown, the overlapping end A is provided with an inclined pin, c, inclining away from the end of the part to which it is Xed. The head of the part B is formed with an inclined opening, d, on the side toward this inclined pin, and fitted to receive the said pin. This pin is caused to hook into the hole by closing the bracelet, so that the point of the pin comes opposite the hole, when, the pressure being removed, the resilience of the spring will bring the hook firmly into place in the hole, and will continue to hold it in that position.
It will be obvious that the form of tlie hook and eye may be greatly varied. tion, insteadl of the hole described and shown, an eye may be soldered to the face of the head next the pin on the opposite head, the pin being adapted to hook into the eye; or two balls may be soldered to pins projecting from both sides, the pins being bent so as to catch-one over the other.
Various forms of hook might be suggested; but the essential principle is that the spring shall act so as to hold the hooks in contact.
I am aware that it is not new to use catches for holding bracelets together, and I do not broadly claim such; but
What I do claim is- A bracelet composed ot' wings hinged together and provided with a spring, said wings overlapping when thebracelet is closed, and being provided with a hook, substantially as described, or one wing adapted to catch and interlock laterally with corresponding part on the other, in combination with the spring actingto hold the hooking devices together, as set forth.
In testimony whereofI have signed my name to this specication in the presence of two subscribing witnesses.
THERON I. SMITH.
