SPECIFICATION forming part of Letters Patent No. 776,763, dated December 6, 1904.

Application filed March 2, 1904.

T0 wZZ whmn it may concern:

Be it known that 1, WILLIAM B. SMITH, of Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Pin-Clasps, of which the following is a specification.

This invention relates to a type of garmentfastening designed to either hold two articles of wearing-apparel in certain relative positions or to hold a portion of one garment in puckered or gathered condition. Several devices of this character have been heretofore produced in which there are prongs or spurs projecting in opposite directions and toward each other, which prongs or spurs are simply caught into the fabric and are retained there in by the arrangement of the opposite projection of thespurs or prongs. These devices will frequently serve to retain the garment or garments in the position desired, provided the latter is kept under suliicient tension to keep the fabric in certain engagement with the prongs or spurs.

The object of the present invention is to provide a device of this character having cloth-engaging points or angular projections at the back of the base member and adjacent to the fabric-engaging spurs, so that if the garment or garments to which the device is connected is loose or is shaken the said clothengaging points or angular projections will prevent the fabric from becoming disengaged from the spurs, the said points or angular projections, however, not being sufficiently rough to tear the fabric ofthe garment.

To these ends the invention consists in the construction substantially as hereinafter described and claimed.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents a perspective view from the rear of a pin-clasp embodying my invention. and 3 represent, respectively, front and longitudinal sectional views of the same. Fig. 4 indicates one of the uses to which the clasp is particularly adapted.

Similar reference characters designate similar parts throughout the several views.

The base member (0, shown as consisting of Figs. 2'

Serial No. 196,203. (No model.)

a plate having a front face capable of being ornamented, has spurs 7), rigidly secured to the rear face thereof. In Fig. 1 have shown two spurs at each end constructed of a piece of wire generally U-shaped and soldered at its middle to the back of the base member a, the two ends of the wire being pointed and projecting parallel with the plate and toward the opposite end of the plate Obviously, however, the number of spurs bmay be increased or decreased without departing from the spirit of my invention. It is also obvious that the said spurs maybe integral with the base memher, if desired.

In order that this device may be practically employed for such purposes as represented in Fig. it-that is, for drawing together different portions of a shirt-sleevc---I have provided means i for preventing the accidental separation of the clasp if the tension under which the clasp is held be considerably re laXed or if the shirt-sleeve be even violently shaken. For this purpose I form a series of cloth-engaging points or angular projections c on the back of the plate a and under the spurs l). The said points or projections may be formed in any suitable way. As represented in Figs. 1 and 3, they are quite similar in form to the usual teeth of a rasp and may be formed in much the same way-via, by indenting the back of the plate by means of a sharp-pointed tool driven thereagainst at an angle, so as to raise from the rear surface of the plate a series of somewhat sharp and inclined points. These points, however, are not sufliciently sharp so as to produce a roughened surface that will be liable to tear cloth. It is my intention to form the back of the base member with a suflicient amount of roughness adjacent to and underneath the spurs to prevent accidental disengagement of the spurs from the fabric with which the pinclasp is engaged. In order to practically secure this result, the points 0 at the two ends of the base are somewhat inclined in directions away from each other, the group at each end being inclined in a direction to oppose disengagement of the cloth from the spurs adjacent thereto.

of, the spurs at each end having penetratingpoints projecting toward the spurs at the other end, the back of the base member under the said spurs having cloth engaging points, the said points at opposite ends of the base being inclined away from each other.

In testimony whereof I have aflixed my signature in presence of two witnesses.
