Specification of Letters Patent.

Patented Feb. 25,1908.

Application filed February 21. 1907- Serial No. 358.644.

Beit known that I, Monnis D. ARNOW, of Boston, in the county of Sufiolk and State of Massachusetts, have invented certain new and useful Improvements in Clasps, of which the following is a specification.

This invention relates to a fastening device for boots, shoes, overshoes, gaiters, gloves and the'like, which may be generally embraced under the term foot and hand' coverings, and has for its object to enable such articles of wear to be quickly fastened, and to be readily adjusted soas exactly to fit the wearer in all parts. Accordingly I form the clasp with interengaging members, one of which has a series of teeth with which the other engages, and arranged so that they may be connected in a wide range'of different positions so as exactly to fit'the hand or foot of the wearer, and to take up looseness dueto stretching after long use.

Of the accompanylng drawings',Figure 1 represents a perspective view of the. upper part of a shoe having my improved clasn applied thereto. Fig. 2 represents a fragmentary front elevation of part of the shoe,

with one of my clasps thereon. Fig. 3 represents a fragmentary section, showing the manner of securing one of the members of the clasp. Figs. 4 and 5 represent plan and sec tional views ofthe clasp as applied to a shoe.

' Figs. 6 and 7 represent perspective views of the members of the clasp when separated from each other. Fig. 8 represents an end view of the socket member of the clasp. Fig. 9 represents a plan of the blank from which the socket member is formed. Fig. 10 represents the device as applied to a glove. Figs. 11 and 12 represent different arrangements for attaching the clasp to a shoe. Fig. 13 represents a sectional view of the socket member showing a modification in construction.

The same reference characters indicate the same parts in all the figures.

The clasp or fastening consists of a socket member at having bottom, side and top walls and open at one end to receive a tongue member b. In the upper or outer wall of the socket member are locking shoulders or teeth 0,

referably made integral by corrugating the lank from which the socket is formed, and these shoulders or teeth are arranged for engagement with an integral spring latch d on the tongue member. The latter is made of sheet metal and between the ends is cut so as shown in Figs. 6 and 8.

to separate three sides of the latch d, leaving the fourth side connected. The latch is bent up so as to lie oblique to the tongue member and to slant outward and rearward from the front end thereof. Thus when the tongue member is inserted into the socket, the latch is depressed by the locking shoultudinal slot e through which project a knob or projection f on the latch d, and a pin g on the forward end of the tongue member. The projection f serves to depress the latch out of engagement with the teeth so that the tongue can be Withdrawn, while the pin 9 is provided for drawing the tongue inward into the socket. I

As-shown in Fig. 9, the socket member is made from a flat blank h of sheet metal. each end of the blank are left one or more prongs i which are pointed so as to be inserted through the material of the part to which they are fastened, and the opposite sides are corrugated by pressure so as to make the teeth 0. The sides are then bent upward on the dotted lines j, and inward toward each other on the lines 70. Adjacent the rear end of the socket the side edges Z extend outwardly sufficiently far to butt together when the socket is shaped, but the edges outside of the teeth are slightly out out so as-to leave the slot 6. At the rear end of the blank are one or more tongues m which bend inward between the inner and outer walls so as to close the end of the socket as The prongs i are bent downward into parallelism and inserted through the material of the hand or foot covering, being then bent back and clenched,

as shown in Fig. 5, to secure the socket.

The tongue member has an extension n on the sides of which are lips or flanges 0 which are adapted to be closed down on short strap members or lugs 10 on the articles to which they are attached. These lips or flan es are pressed down tightly and may be acte upon by a machine which cuts and forces spurs from the metal into the leather of the shoe,

etc., at the same time that the lips are being clamped. Preferably the body of the tongue I) and the extension a are made in separate parts, although they may also be integral, and are pivotally connected by a projection g on the part at which passes through a slot 7 in the rear of the tongue body, and is doubled back over the edge thereof. This makes a sort of pivotal connection, *givingflexibility to the tongue member.- The tongue members are attached to lugs 12 as before described, and these latter may be formed integrally with the upper of the shoe by cutting awa the latter adjacent the edge, asshown in igs. 1, 2, 3 and 11, or the lugs may be formed .uponrarstrip aseparatelysewedato@the outside :of the up er adjacent and parallel with the edge it ereof. In applying ithe fastening to gloves, one or imore tabs 25 of leather .zare :sewed eat one .end xto ithe sglove, and the other end is clamped by the 'lips o of the tongue member, as described.

.It will bBillIldHlSllOOd that Figs. '4 to '9 inclusive show the clasp onza greatlyaenlarged scale, for the purpose of clear illustration. Actually theadevice :will be :mad'edof approximately the same size as "the illustration Fin Fig. 1.
