IMPROVEMENT IN CORSET-CLASPS AND.SPR|NGS.

The Schedule referred to in these Letters Fatent and making part of the same.

Beit known that I, PETER H. NILES, of the city of Boston, county of Suffolk and State of Massachusetts, have invented a new and useful Improvement', in Corset-Olasps and Springs; and I do hereby declare declare that the following is a full and exact description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon.

To enable others'skillc-d in the art to make and use my invention, I will proceed to describe its construction and operation.

Upon-the accompanying drawing- Figure 1, A, is an elevation of a corset-spring (right) having a local graduated corrugation, a. It is provided with spring-clasps b b b, which are attached to and form part of said corset-springs. The corrugations a are enlarged at the center, laterally, and are also deeper at the center, longitudinally, tapering graduallyto the-ends; this strengthens the corset-spring at the exact spot where a stay is required, for corrugations at the end do not accomplish this purpose, having no eect, as they do not come where the strain is received.

Figure 1, B, is an elevation of a corset-spring (left) having a local graduated corrugation, and is provided with buttons c c c;

Figure 2 is an elevation of a pair of corset-springs (corrugated) connected by the spring-clasps b b b, and showing the buttons c c c retained in the angle of the `ktwoway slots by the spring of the clasps.

angled slots e; said clasps are located at suitable points along the spring A, and at corresponding points` on spring B are the projecting studs C, which have enlarged heads which enter orifices d d simnitaneously, and the spring is then moved in either direction vertically if the studs Center thc upper orifices, and laterally if they entertbe lower orifices, until said studs are in the angle of slots e, where they are firmly held, the clasps forming double-acting springs with sutlicient strength to prevent them from detaching themselves, a fault common to many corset-clasps.

The clasps are detached by reversing the clasping operation, that is moving the studs C- simultaneously into either of the orices (l ll.

The corset-spring of `W'allace Fowler'diers from mine in the fact that it has corrugations at the ends of the spring, which corrugations are ofthe saine depth to their whole extent, which form does not aci eomplish the purpose of my corrngation, it comes upon that part of' the spring which docs not require a back stay, while my spring has a corrugation deeper and broader in the center, gradually diminishing in width and depth each way, said corrugation being located at thecenter ofthe spring where the'mziststrength is needed.
