GEORGE MANGGANG, OF SYRACUSE, NEW YORK, ASSIGNOR TO THE SYRA- CUSE SPECIALTY MANUFACTURING COMPANY, OF SAME PLACE.

SHOE-CLASP.

SPECIFICATION forming part of Letters Patent No. 474,914, dated May 17, 1892.

Application filed August 1, 1891. Serial No. 401,390. (No model.)

To aZZ whom it may concern;

Be it known that I, GEORGE MANGGANG, of Syracuse, in' the county of Onondaga, in the State of New York, have invented new and useful Improvements in Shoe-Clasps, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to the class of shoeto clasps which are usually applied to arctic overshoes and in which a frame attached to one of the quarters or straps of the shoe is provided with a spring-actuated tongue interlocking with a slotted catch-plate attached to IS the opposite quarter or strap of the shoe; and

the invention has special reference to the species of clasps in which the tongue has rigid pintles of angular form in, cross-section serving as cams inserted between the elastic free ends of two plates which are firmly united at their rear ends and constitute the support ingframe of thetongue; and my present invention consists in an improved construction and combination of parts designed to maintain the two plates of the tongue-supporting frame more securely laterally in their position in relation to each other and also guard more effectually against the disrupture of the tongue from said supporting-frame.

0 The invention is fullyillustrated in the annexed drawings, in which Figure 1 is a side view of a clasp embodying my improvements. Fig. 2 is a plan view of the same. Fig. 3 is a side view showing 33 the clasp in its open position, and Fig. at is a perspective view of the component parts of the clasp in a segregated condition.

Similar letters of reference indicate corresponding parts.

40. .D represents the usual and well-known slotted catch-plate, which is attached to one of the quarters or straps of the shoe and with which interlocks-the tongue 25, connected to a frame attached to the other quarter or strap of the shoe. This frame is formed of two plates 0 0, usually stamped out of sheetsteel and placed flatwise, one upon the other, andfirnily united at their rear or attaching end, preferably by means of a rivet r, passing through the plates. One of said plates, preferably the underlying plate 0, has its free end formed with two arms a a, each of which terminates with two fingers b b, projecting upward at right angles from the plane of the plate and with a recess 0 between said fingers, 5 5 as clearly shown in Fig. 4 of the drawings, and also with a depression d immediately back of the fingers b b, for the purpose hereinafter explained. The other or overlying plate 0' has its free end formed with similar 6o arms a a, terminating with fingers e e, extending forward and through the recesses c c, and thus restrained from lateral displacement by the fingers b b, engaging opposite edges of each finger e.

The angular or cam-shaped pintles t t of the tongue 25 are inserted between the aforesaid arms of the two plates C 0' immediately back of the fingers b b, and are thus seated in the depressions cl (1 of the plate C, which de- 7c pressions are only of such adepth as to cause thetwo plates 0 C to lie contiguous to each other and bear on the flat sides of the pintles t if when the clasp is in its closed position, and in opening the clasp the raising of the free end of the tongue if from its supportingfraine causes the pintles t t of said. tongue to pry the free ends of the plates 0 C apart and receive therefrom the requisite spring action,which partially locks the tongue in its open and closed positions. I

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

The improved shoe-clasp composed of two 8 plates C C, placed one upon the other and secured to each other at their rear ends, one of said plates having its free end formed with two arms a a, each terminating with-two fingers b b, projecting at an angle from the'plane 9c of the plate and with a recess 0 between said fingers, and the other of said plates formed with similar arms a a, terminating with fingers e 6, extending forward through the recesses c c, in combination with the tongue 25, having the angular pintles t t inserted between the aforesaid arms of the two plates immediately back of the fingers I) Z), substantially as described and shown.

In testimony whereof I have hereunto 10o signed .my name this 29th day of July, 1891.
