SAFETY-PIN.

SPECIFICATION formingpart Of Letters Patent N0. 671,615, dated April 9, 1901.

Application filed October 17, 1900. Serial No. 33,357- (No model.)

To all whom it may concern:

Be it known that I, ELBERT SNEDEKER, a citizen of the United States of America, and a resident of the borough of Brooklyn, in the city of New York and State of New York, have invented certain new and useful Improvements in Safety-Pins, of which the following is a specification.

This invention relates to improvements in safety-pins.

It is the especial purpose of this invention to provide a safetypin with a housingclasp which shall securely hold and protect the point, yet which can be easily opened, and also with a spring so coiled in the reverse of the ordinary coil of safety-pin springs that the opening of the point tends to wind up or tighten the spring and also so that the coil crosses the body of the pin, so as to present a square shoulder'which will prevent the fabric from slippinginto the coil of the spring. With the spring thus coiled the length of the pin, which is liable to deflection under strain, is rendered the shortest possible, while the effective available length of the point is made the greatest possible.

Referring to the drawings which accompany this specification to aid the description, Figure l is a longitudinal elevation of the pin with the clasp opened, and Fig. 2 is a longitudinal elevation of the pin with the clasp closed. Fig. 3 is an edge elevation of the clasp closed and with the point in place, and Fig. 4 is a detail edge view of the spring.

The body aand pointed bar I) are connected by the spring 0, which may have any number of coils, and the direction of the coils is the reverse of that in ordinary safety-pins and so that the opening of the bar 1) tends to tighten the spring, whereby the spring gives much additional strength to the bar and reduces the liability that strain on said bar I) will withdraw the pointfrom its housingclasp. The coils of said spring are also arranged, as shown, so as to oppose a practically square shoulder at d to prevent fabric from entering the spring, and the whole length of the bar I) is available to pin into a fabric. The said body a is bent at its front end into a loop with a straight bar 6, on which is pivoted the housing-clasp f, which is of sheet metal and shaped about as indicated, with the hinge-sleeve g, the lug 72, to guard the pinpoint, and the thumb-piece j. Adjacent to the thumb-piecej the clasp f is so curved as to constitute a spring-catch, which firmly binds on the'main bar of the body a when the housing-clasp f is shut, Fig. 3. When the point of bar I) is in said housing-claspfand that is closed, said point bears on the hingesleeve g, and any strain on the said point tends to the more firmly hold the clasp shut, for there is, unavoidably, very little play between the said sleeve 9 and the bar a, and also any tendency of the metal of the clasp to yield to the strain on the barb tends to hold the said clasp firmly closed.

Now, having described myimprovements, I claim as my invention- 1. The combination in a safety-pin, of a body provided with a loop, a pointed bar, a spring connecting said body and pointed bar, and a housing-clasp adapted to hold said point against a part of said loop and pivoted on the loop of said body parallel to the length thereof and provided with a spring-clasp adapted to engage on another part of said body and protect said point when said housingis closed, substantially as described.

2. The combination in a safety-pin, of a body a, provided with a loop, a pointed bar I), and a spring 0 connecting said body and pointed bar, and coiled as described, so that the opening of said pointed bar tightens said spring, and a housing-claspfadapted to hold said bar 1) against a part of said loop and provided with a hinge-sleeve g on a bar 6 of said loop and a thumb-piece j adapted to engage on said body a, substantially as described.

3. In a safety-pin and in combination with the body a provided with a loop and pointed bar 19, a housing-clasp adapted to hold said bar I) against a part of said loop and hinged on a part 6 of said body parallel with the length of the pin and adjacent to the closed point, whereby said point presses on the hinge of said clasp, substantially as described.

Signed at New York city, New York, this 15th day of October, 1900.

ELBERT SNEDEKER.
