SHOE-CLASP.

SPECIFICATION forming part of Letters Patent No. 313,388, dated March 3, 1885.

. ApplioatiOn filed August 12, 1884.

T all whom it may concern:

Be it known that I, JACOB J. UNBEHEND, 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 has reference to the class of IO shoe-clasps in which a slotted plate attached to one of the flaps of the shoe interlocks with a tongue hinged to a plate attached to the other flap; and the invention consistsin an improved construction of the last-mentioned plate and its connection with the tongue, whereby the manufacture thereof is simplified and the cost of the same materially reduced, and, further more, undue pressure on the foot of the wearer of the shoe incident to the operation of opening and closing the clasp is obviated.

Referring to the annexed drawings, Figure l is a side View of my improved clasp with the tongue in position for retaining the interlocking slotted plate. Fig. 2 is a plan view of the same. Figs. 3 and 4 are detached plan views of the tongue and its attaching-plate, respectively,and Figs. 5 and 6 illustrate modifications of the construction of the latter.

Similar letters of reference indicate corre- 3o sponding parts.

A denotes the usual transversely-slotted metal plate designed to be attached to one of the flaps of an Arctic overshoe. Bis another metal plate adapted to be secured to the other flap of the shoe, and 0 represents the tongue which is hinged on the plate B and adapted to enter one of the slots of the plate A, and effectually interlock with saidplate by drawing it over onto the plate B, as represented by 0 dotted lines in Fig. 1 of the drawings.

The connection of the tongue 0 with the plate B, I form as follows, to wit: The plate B,I provide with two eyes or pintle-bearings, b b, a proper distance apart to receive between 5 them the end of the tongue to be hinged thereon, and at the outside of said eyes I provide the plate with elastic lips or spring extensions e e, which are integral with the plate and formed by longitudinal slits c c in theend of the plate B, at the outside of the aforesaid (No model.)

eyes or bearings b b, as shown in Fig. at of the drawings. The tongue 0, I provide with a pintle, a, which may be either integral therewith or rigidly attached thereto in any suitable manner. Said pintle projects from opposite edges of the tongue, and the ends thereof extend through the eyes I) b,and across the elastic lips e e, and are flattened or angular in crosssection in such a manner that when the tongue lies upon the plate B, as shown in Fig. 1 of 6 the drawings, one of the flat sides of the pintle lies upon the elastic lip. In raising the free end of the tongue the angles of the pintle which turns with the tongue exerts a downward pressure on the lips e c, the resistance of which serves to automatically hold the tongue in its aforesaid position upon the plate B, and also throw the tongue into its distended or open position after the same has passed over the center of its movement. 7c

By the employment of the flattened or angular pintle in lieu of the cam formed on the tongue, as heretofore constructed, I materially reduce the cost of manufacture, and also relieve the'wearer of the shoe of undue pressure'of the spring upon the foot in the opera tion of opening and closing the clasp, inasmuch as the pintle is above the plane of the plate B, while the cam formed on the tongue as heretofore is necessarily more or less below the said plate or projects more or less from the axis of the tongue. I do not, however, limit myself to the specific arrangement of parts just described, as it is obvious that the flattened or angular hinge-pin may be rigidly attached 8 5. to or made integral with the plate B, as shown in Fig. 5 of the drawings, and the tongue 0 formed with a sleeve, 5, by which it is hung on the hinge-pin, and with elastic lips e at the sides of the sleeve, as represented in Fig. 6 of the drawings, said lips pressing on the hinge-pin when the parts are united.

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

l. The combination, with the tongue 0 and plate B, of a flattened or angular pintle, by which the tongue is hinged on said plate,.and spring-lips on either the tongue or plate bearing on the aforesaid pintle to receive the im- 100 pingement of the angles thereof when swing- In testimony whereof Ihave hereunto signed ing the tongue back and forth on the plate, my name and affixed my seal, in the presence substantially as set forth and shown. of two attesting witnesses, at Syracuse, in the 2.

elastic lips e e at the outside of said eyes, and the pintle a, flattened or angular in cross-see JACOB J. UNBEHEND. [L. s] tion, projecting from opposite edges of the tongue and through the eyes 12 b, and across 10 the elastic lips e e, substantially as described Witnesses:
