SAFETY-PlN.

SPECIFICATION forming part of Letters Patent No. 378,318, dated February 21 1888.

Application filed October 6, 1887. Serial No. 251,587. (No model.)

To aZZ whom, it may concern-.-

Be it known that I, JOEL JENKINS, of Montclair, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Safcty-Pins; and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification, in which-- Figure l is an elevation of my improved reenforced safetypin; Fig. 2, a transverse sec tion in line It a of Fig. 1; Fig. 3, an elevation of the pin when provided with a guard for the shield in combination with the re-enforc ing sleeve; Fig. 4, an elevation of a safetypin, illustrating the combination therewith of a re-enforcing sleeve made integral with the shield and its guard, Fig. 5 being a plan of the blank from which the shield, sleeve, and guard are struck up, and Fig. 6 a side elevation of the blank when bent and drawn into shape to apply to the pin.

In the use of a safety-pin for uniting and confining two separate pieces of fabric itoften occurs that a strain upon the pieces of fabric tending to pull them apart will, by means of the strain thereby created upon the two ends of the pin, so far bend the bar of the pin as to allow the pin-point to become disengaged from the shield, thereby releasing the pin and allowing the fabric to drop therefrom.

The object of my invention is to prevent this disadvantage in the use of the ordinary safety-pin by preventing the bar from yielding under any ordinary strain which may, without tearing, be resisted by the fabric held by the pin.

It consists in the combination of a reenforcing sleeve formed or fitted upon the bar with a guard made to project from the sleeve toward the outer end of the shield of the pin and in front thereof.

In the accompanying drawings, A represents the bar of a safety-pin; B, its springcoil; 0, the pin and point, and D the shield under which the point is caught and protected.

E represents a re'enforeing sleeve of sheet metal encircling the entire length of the bar from the shield to the spring-coil. This reenforcing sleeve is simply made of a piece of sheet metal bent and closed about the bar to To still further guard against a fiexure of 6 the bar, a guard-piece, F, may be formed integral with the sleeve E at its inner end, to project radially therefrom immediately in front of the end of the shield, as shown in Fig. 3. I also contemplate making the re-enforcing sleeve in one piece with the shield and guard, as shown in Figs. 4c and 6. In this case a blank of sheet metal is out in substan tially' the form shown in Fig. 5, a long narrow strip, Z, being left for the sleeve, a lateral offset, m, for the guard, and opposite terminal offsets, n n, for the lips of the shield.

The blank is folded longitudinally in the middle, and its lip end is bent and simultaneously drawn so as to form the shield, as shown in Fig. 6, the lateral offset on being left projecting radially from the body of the piece in front of the ends of the lips n n of the shield. The bar of the pin is then inserted into the folded blank with its bent end within the U-shapcd portion thereof, and the blank is closed and clamped upon the bar and its bend, so as to be firmly united thereto. In being closed about the bar the portion 1 of the blank assumes a tubular form, (see Fig. 6,) and constitutes the re-enforcing sleeve E of the finished device, and the portion a it forms the customary shield, while the part m projects, as a guard, F, in front of the end of the shield, to prevent the fabric held by the pin from rest ing against or straining upon the end of the shield, and, in combination with the lips or a of the shield, to prevent the pin passing directly through from side to side under the shield.

I do not herein claim the combination of a guard, F, with the shield of a safety-pin, as I have made this feature of my invention the subj ect-matterofaseparate application for Let upon said bar, to encircle the same and coin plete and re-enforce the pin, substantially in the manner and for the purpose herein set 1 forth.

In testimony whereof Ihave signed my name to this specification in the presence of two subscribing witnesses.

JOEL JENKINS.
