SHOE-CLASP.

SPECIFICATIQN forming part of Letters Patent No. 404,023, dated May 28; 1889.

Application led November 19, 1888. Serial No.291,272. (No model.)

To @ZZ whom it may concern..-

Be it known that I, GEORGE A. IVELD, of Vinchester, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Shoe-Clasps, of which the following', taken in connection with the accompanying drawings, is a specification.

The object of my invention is to so construct a device that the parts when united may together form a cheap, easily-working, and durable clasp. This object I attain by the construction shown in the accompanying drawings, in whichm Figure l is a plan of one of my clasps complete. Fig. 2 is a longitudinal section taken on line x a: of Fig. l. Fig. 3 is a section, in part, taken on line y y of Fig. l. Fig. 4 is a plan of the part that forms the spring-plate; also shows a part of the tongue. Fig. 5 is a cross-section taken on line z e of Fig. 1. Fig. 6 is a cross-section taken on line ze of Fig. 8. Fig. 7 is a plan of the base-plate of the clasp as it is made by the blanking-die, and Fig. 8 is the base-plate of the clasp as it appears when the pivot-holders are folded back onto the plate.

The attachingplate B, Figs. l4 and 2, is made with openings C C C2 O3, in the usual manner, and adapted to engage with the tongue D.

The main plate A is first cut into the form shown in Fig. 7, it having ears HH H H, as shown. These ears are bent back and folded onto the plate, as shown in Figs. 3, 5, 6, and 8, so as to form stay-pieces for the pivots d (see Figs. 3, 4, and 5) for the tongue D.

The plate A is folded on the line fn, n, Fig. 7, so as to inclose the pivots d d of the tongue D, and also embrace the spring-plate E, Fig. 2. It is then made fast by the rivet A2, which passes through holes a ct of the plate A and a2 of the spring-plate E. Thus the single rivet a2 holds the Whole firmly together.

As the end D of the tongue D extends beyond the pivots d d, (see Fig. 4,) it is evident that the act of turning this up to connect or detach the plate B will cause a deflection of the spring-plate E, and that the reaction of the spring-plate E will have a tendency to hold the tongue D in either position, open or shut.

The main plate A has depressions A3 A8, (see Figs. S and 2,) to make room for the ears H H and pivots d d. (See Fig. 3.)

By the device of the folded-back ears H H and the depression A3, I am enabled to secure a rm and compact socket for the pivots CZ d of the tongue D to rest in.

In order to cause the cross-bars K K K of the attaching-plate B to stand somewhat above the levflof the unler side of the plate B, and thus engage in a better relative positionwith the tongue D, I form ribs B B on the under side. (See Figs. l and 2.) These ribs B B also render the bearing-surface of the plate B on the vamp much better adapted to fit easily, and not to chafe or Wear the vamp.

I am aware that it is not new to bend the ears at right angles on clasp-plates for the purpose of forming guards to hold the hingepins. My device consists in folding the ears H H back onto the plate and in holding them firmly between the folds of the plate, as shown in Fig. 3.

I claiml. In a shoe-clasp, the combination of the main plate A, having inwardly-folded ears H H and depressions A3 A3, adapted to be doubled onto itself, with the tongue D, substantially as described, and for the purpose set forth.

2. In a shoe-clasp, the attachment-plate B, having depressed ribs B B', adapted to rest upon the sides of the clasppiate A A and to hold the cross-bars K K K above the springplate E, with the spring-plate E and claspplate A A substantially as described.

GEORGE A. VVELD.
