JACOB J. UNBEHEND, OF SYRACUSE, NEW YORK, ASSIGNOR- TO JUDSON L. THOMSON 8: CO., OF SAME PLACE.

SHOE-CLASP.

SPECIFICATION forming part of Letters Patent No- 384,339, dated June 12, 1888.

Application filed December '3, 1887.

To aZZ 1 0710772 it may concern/.-

Be it known that I, JACOB J. UNBEHEND, of Syracuse, in the county of Onondaga, in the State ofNcw York, have invented new and 5 useful Improvements in Spring Shoe-Clasps, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

My invention relates to improvements in [O spring-clasps adapted for use upon arctics,

overshoes, and the like articles, and the object is to provide a simple, efficient, and eco' nomicallyconstructed springclasp which will produce the desired result and shall be very t5 economically manufactured; and to this end the invention consists in the combination, in a springclasp, of a base-plate having its side edges bent substantially at right angles to the main portion of the plate, and the bent parts provided with notches or indentations for the reception of the tonguepivots, a hook-shaped tongue having cam or flattened pivots seated in the notches or indentations in the angular edges of the base-plate, and a supporting spring-plate connected to the base-plate by suitable fastening means and bearing on the tongue, thereby retaining the tongue-pivots in the notches formed in the bent edges of the base-plate, all as hereinaftermore fully described, and pointed outin the claims.

In specifying my invention reference is bad to the accompanying drawings, formingapart of this specification, like letters indicating corresponding parts in all the views, in which-- Figure 1 is an edge view of my improved spring-clasp, illustrating the general construction and arrangement of the parts, the holding tongue or lever being open for the purpose of showing the operation of the spring- 0 plate on the pivots of the holding lover or tongue. Fig. 2 is alike view, in which the base-plate having the bent angular edges is reversed in construction to that shown in Fig. 1; in other words, in Fig. 1 the base-plate is 5 shown to be the upper plate, with the angular edges bent down and provided with the pivotsockets, while in Fig. 2 the base-plate is underneath, and the angular edges are bent up on the inside and provided with the notches forming the pivot-sockets with the spring- Serial No. 256,729. (No model.)

plate resting on the end of the hook-shaped tongue. Fig. 3 is an isometric view illustrating a further modification in which the baseplate is constructed substantially similar to the form shown in Fig. 1, excepting that the spring-plate is provided with coincident forwardly-projecting arms hearing on the fiattened pivots of the tongue. Fig. et shows the blank of the baseplate, and Fig. 5 the springplate of the construction illustrated in Fig. 2.

(t denotes the baseplate provided with a forwardly-extcnding bifurcation and arms a. a. The arms a to terminate on their edges with sidewise-projecting extensions (1 d, having notches or. opposite ear'h other in the said extensions. The extensions d d are bent at substantially right angles to the main portion of the baseplate a, so that the notches a project vertically and form seats for the pivots p of the hook-shaped'tongue t. The tongue t is provided with camshaped or flattened pivots 1), formed preferably from the material from which the tongue itself is struck up, and the said pivots p are seated in the notches or indentations a in the base-plate, as shown at Figs. 1, 2, and 3. In order to support the tongue on the base-plate, and to retain the pivots 1) thereof in their seat in the notches or indentations 12,1 provide a spring-plate, b, having an extension or extensions, c, which bear on the tongue and retain the pivots in the notches n.

The spring-plate b is provided with aslot,s, coincident with the slots in the piate c,and the said springplate b is connected to the plate a. by any suitable fastening, as the eyelet-rivetj, Figs. 1, 2, and 8; but I do not restrict my in vention to the particular fastening means shown,since any suitable fastening for connecting the two plates may be employed. Neither do I restrictniy invention to the specific construction illustrated and described herein, since the angular edges or extensions dd may be either on the outer edge of the base-plate a and project downwardly, as shown 95 in Figs. 1 and 3, or they may be on the inner edge of the base-plate a and project upwardly, as shown in Fig. 2. The only difference would be that where the angular edges (1 61'' project downwardly the baseplate a forms the upper [c0 plate of the clasp-frame, and the supportingspring b, with its extensions 0, bears upwardly and supports the tongue from below, whereas in the other case,where the notched edges dd project upwardly,the plate a forms the under plate of the clasp-frame,and the spring-plate, with its extensions c,loears against the tongue t.

The tongue or holding-levertishook-shaped, as best shown in the edge views, Figs. 1 and 2, and the laterally-projecting pivots p are camshaped or flattened, so as to exert a strain on the spring-plate b when the tongue or holdinglever is operated in opening and closing the clasp, and the camshaped or flattened pivotsp correspond to the shape of the notehesnin the base-plate a,and the said notches n serve as the hearings or sockets for the said pivots of the tongue or holding-lever.

At Figs. 4 and 5 I have illustrated the detail construction of the blanks for the base-plate a and spring-plate b as employed in the clasp shown in Fig. 2.

To construct the clasp as shown in Fig. 1,it is simply necessary to form the blank shown in Fig. 4 with the notched extensions d d on the outer edges of the arms a a, instead of on the inner edges,as shown in the said figure,and the spring-plate I) may have two extensions, 0 c, coincident with the arms aaof the base-plate a. In either case, however, the extensions 0 c bear on the tongue 25, and thereby retain the pivots p in the notches a.

WVhere the extensions 0 c of the spring-plate b are central, as shown in Fig.5, the extension 0 bears on the hook-shaped edge of the tongue t midway between the forwardly-extending arms a a of the base-plate, and where the free end of the spring-plate Z) terminates in two extensions coincident with the arms a a the said hook-shaped portion of the tongue t. The clasp is simple in construction, compact, and effective for the purpose intended.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a spring-clasp, the combination of a base-plate having its side edges bent at right angles to the main portion of the plate and the bent parts provided with notches or indentations for the reception of the tonguepivots with the tongue having cam-shaped pivots seated in the indentations or notches in the angular edges of the base-plate, and a supporting spring-plate connected to the base-plate and retaining the tongue in the sockets on the baseplate, substantially as and for the purpose set forth.

2. I11 a spring-clasp, the combination of two sheet-metal plates, a b, secured together at one end, the plate a bifurcated at its opposite end and provided with sidewise extensions bent at right angles to the plate, and having notches n n therein forming bearings for the tonguepivots, the other plate, I), having its free end terminating in extensions 0, which are adapted to rest against the base of the tongue or holding-lever and confine the tongue-pivots in their bearings in the plate a, the hook'shaped tongue-lever 15, its hook-shaped end constructed with 1aterally-projecting flat pivots p, corresponding to the notches n in the bent edges of the plate a, substantially as and for the purpose set forth.

In testimony whereof I have hereunto signed my name, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 30th day of November, 1887.

JACOB J. UNBEHEND.
