CORSET-STEEL FASTENING.

SPECIFICATION forming part of Letters Patent No. 295,171, dated March 18, 1884.

Application iilcd September E, 1853.

To aZZ whom it may concern:

Be it known that I, LUOIAN HILL, of North Brookfield, county of Worcester, State of Massachusetts, have invented an Improvement in Corset-Steel Fasteuings, of which the following description, in connection with the accompanying d rawings,is a specification, like letters on the drawings representing like parts.

This invention has for its object the production of a simple and efficient lock-clasp or fastening device composed of a loop-like piece of metal closed at its outer end, and having one or both of its ends connected loosely with and so as to be free to move on or with relation to the steel, the inner wall or edge of the loop being shaped to present two stud-receiving openings of different diameter connected by a slot of less width than the diameter of the stool; of the opposed steel.

Prior to my invention an eye-plate has been employed having its outer end slotted to constitute two spring-arms; but when the said arms are subjected to considerable strain, or become twisted out of the same plane, the stud is liable to pass out from the said slot, leaving the corset loose.

In. another application filed by ine'I have shown a one-piece loch-clasp having one or more spring-arms located within a plate firmly riveted upon the steel; but such a lock-clasp requires for its production more metal and is more expensive to manufacture.

Figure 1 represents asuilicient portion of a. pair of corset-steels to illustrate one embodr ment of my invention; Fig. 2. a section of Fig. l on the dotted line a: m,- Fig. 3, a detail of the fastening device or lock-clasp removed; Fig. 4., a modification; Fig. 5, a detail oi the slotted steel of Fig. 4.; Fig. 6, the lock-clasp of Fig. 4 removed; Fig. 7, a section of Fig. 4. in the dotted line m. Fig. Sis yet another modification; Fig. 9, a detail of the slotted spring of Fig. 8, and Fig. 10 shows the lockclasp of 8 removed.

Referring to the drawings, the steels A B and the headed studs 0 are all as usual. The loclrclasp D is coinposedof a springmetal loop, the free ends (1 cl of which are next the edge of the steel A. The inner edge or wall of the loop D is so shaped as to leave an opening, 2, of greater diameter than the head of the stud c, and an opening, 3, of less diameter than the head of the said stud, the two openings being connected by means of a (No model.)

slot or space, which at some point, as at 4, is of less width than the diameter of the stud 0 below its head.

In Figs. l to 3 the end d of the loop,which constitutes the fastening or lock-clasp, is riveted closely to the stceltA by two rivets, 5 6

but the end d of the said loop has in it ahole or slot of greater diameter or area than the diameter of the rivet or pin e embraced by the end (1, so that the said end may move provide the end d with a fixed stud, e, to en'- ter and move in the said slot.

In practice I lind it necessary to have but one end of the fastening or lock-clasp attached to the steel loosely; but I may. as I sometimes find it desirable, connect both the ends at d loosely with the steel A, a small amount of lost motion being provided for the difference between the diameters of the rivets 5 6 and the slots f f, in which they enter, as in Figs. 8 and 9.

I do not claim a latch operated by a spring, as in United States Letters Patent No. 247,015; nor do I claim a corset-steel combined with a longitudinally-arranged spring or series of wire loops which are adapted to more laterally with relation to the length of the steel and under bridge pieces attached to the steels, as in United States Letters Patent No. 238, 7 31.

Iclaini The steel B and its headed stud, combined with the steel A and its an tached clasp D, one end of the said clasp being connected loosely with the said steel, whereby the clasp is permitted to expand laterally as the stud passes from the larger into the smaller part of the eye of the clasp, and then springs back of and locks the said stud in the smaller part 3 of the clasp, all substantially as set forth.

In testimony whereof I have signed my name to this specification inthe presence of two subscribing witnesses.

LUCIAN HILL.
