SAFETY-PIN.

S1 ,CIEICATION forming part of Letters Patent No. 367,107, dated July 26, 1887.

Application filed Januar? 3, 1887. Serial No. 223,182. (No model.) I

To all whom it may concern:

Be it known that I, JOEL J ENKiNs, of Montclair, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Wire Safety-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 theletters of reference marked thereon, making a partof this specification, in which- Figure 1 is a view of the wire from which the pin is made, with its bluntend looped and twisted. Fig. 2 is an elevation in perspective of my improved Wire safety-pin; Fig. 3, aside view thereof, and Fig. 4 a section in line 00 w 'of Fig. 2. My invention relates to that class of safetypins in which the shield or guard for the point is made of wire integral with the body of the pin, and has for its object to strengthen the shield, prevent the pin-point from pressing forward beyond the shield, and insure the ready entrance of the point into the loop of the shield from either side of approach thereto. These objects are accomplished by doubling and twisting upon itself the end of the pointed wire which is to form the guard or shield, as hereinafter particularly described, so that the doubled end shall form a loopor shie'ld,within which the pointed end of the pin may enter and be guarded, and thetwisted portion shall form a stop againstwhich the point shallstrike if it be accidentally or otherwise pushed for-,

ward too far within the loop, while the extreme free end of the twisted wire is made to project inward toward the center of the loop at an angle with the bar of the pin and in the plane of its vibration, so as to serve as a' guide for the pin on entering the loop from either side.

My improved safety-pin is made of a bit of tempered wire, A, (see Fig. 1,) pointed at one end, B, to serve as a pin, and coiled or doubled at a suitable point, C, in its length to form a spring, dividing the length of wire into two arms, of which the one, A, constitutes the .pin proper, and the other, D, the main bar of the safety-pin. In these particulars the improved safety-pin does not differ, essentially, from those now in public use.

The end of the Wire A, which is to form a v 1 guard for the pin A, is doubled upon itself to form an open loop, as at E, and is then twisted together, as shown at F in Fig. 1, for the distance required to form the length ofthe curved guard F, and, finally, the free end G of the twisted wire is left-to project at an angle with the bar; D, as shown in Fig. 1. The twisted and looped end E F is then doubled back over the bar D in a circular curve, forming the guard F, (see Fig. 2,) and the loop E is bent inward toward this curved guard (see Figs. 2 and 3) to form a shield for the point of the pin A, which may besprung in between the two sides of the bent loop of the shield, as shown in Fig. 2., The loop is thus made to serve as an efiective shield for the pin-point, while the twisted body of wire at the curved end F of the safety-pin presents alsufficiently-wide surface immediately in front of the pin-point, when it is confined in the shield-loop, to serve as a stop for the point and prevent it from being pushed forward longitudinally beyond the shield when it is so confined in said loop.

The free end G of the doubled twisted wire in the guard is brought into line with the shield loo-p E about midway between its two sides (see Fig. 4) and near to its outer open end, (see Figs. land 3,) and projects from the bar D of the pin, so as to nearly reach the loop, and it is sharpened at its extremity, so as to offer no resistance or point of lodgment for the pin-point when pressed in toward it. This sharp projecting end G serves to guide the pin-point into the loop when the point is carried toward it from either side. 7

The form of the loop E, constituting the shield for the pin, may evidently be varied without departing from my invention.

I am aware that safety-pins haveheretofore been constructed with guards or shields formed integrally with and of the same piece of wire as the pin itself, and also that the blunt end of the piece'of wire whose opposite end forms the pin has been made to project'from or within a shield of sheet metal, constituting a guard for the pin-point, so as to serve as a guide for confound either for preventing the pin from being pressed forward longitudinally out of the shield or for guiding the pin into the shield-loop.

By my invention I overcome these defects in a safety-pin made whollyof one piece of wire, and obtain at the reduced cost attendant upon the manufacture of a pin wholly from asingle piece of wire all the advantages found in a safety-pin made with a separate guard or shield of sheet metal and provided with a guide. I thus combine in one article all the advantages without any of the disadvantages to be found in the best pins of both descriptions heretofore made.

I claim as my invention" 1. The combination, with the bar and shield of a safety-pin made in one of a single piece of wire, of a twisted guard, formed substantially as described, integral therewith and interposed between the shield and bar to con meet them and to present a comparatively wide solid stop, which will prevent the pinpoint, when inclosed by the shield, from being 20 forced forward beyond it, substantially in the manner and for the purpose herein set forth.

2. In a safety-pin made of a single piece of wire, the shield-loop E, and the twisted guard F, connecting the loop with the bar D of the 25 pin, in combination with the guide G, formed integral with the wire of the pin, and arranged and operating substantiallyin the manner and for the purpose herein set forth.

In testimony whereof I have signed my name 0 to this specification in the presence of two subscribing witnesses.

JOEL JENKINS.
