MANUFACTURE OF SAFETY-PINS.

SPECIFICATION forming part of Letters Patent No. 237,661, dated February 8, 1881.

Application filed October 1,1879.

To all whom. "it may concern:

Be it known that I, JOHN P. COURTNEY, of the city of Brooklyn, county of Kings, and State of New York, have invented an Improved Sat'ety-Pin, of which the following is a specification.

My invention consists in making a safetypin by first forming the point on a piece of wire or blank of the proper length, then producin g a flattened or roughened surface on the other end, then tinning said roughened surface, and then placing it in a mold of the proper shape to form a shield or clasp by casting melted metal in the mold around said tinned surface, then bending the wire at or near its center one or more complete turns to form a spring, so that the point may be turned into the clasp of the shield and held therein by its elasticity, as will hereinafter appear.

In the drawings, at A, Figure 1, is a blank or piece of wire pointed atone end and flattened or roughened at the other end, and in which condition it is tinned, ready to receive the cast metal for forming the shield or clasp, an outline of whichis shown at B, Figs. 2 and 3, and a cross-section at Fig. 4. Said tinned end of the blank is then placed in a mold of the proper shape to form the shield or clasp, as shown at B, and then the metal known as White-metal, or other suitable composition or alloy, is poured into the mold, by which a shield or clasp is formed on the said roughened end'of the pin, and in which condition it would be represented, as in Fig. 2, by the solid lines, which show the pin extending straight out from the clasp as an ordinary pin. The

said pin is then bent, at or near its center, around a small pivot or mandrel to form one or more turns, as shown at C, and for the purpose of forming the spring to hold the point in the clasp or shield B, and as shown by the dotted lines in Fig. 2 and in the solid lines in Fig. 3, in which last figure the safety-pin is represented as completed and with the point resting in the clasp, as it is required to be when in use.

At Fig. 4 the section shows the shape of the recess, as at D, for the point of the pin, and also theopening, as at E, for the point to enter into the clasp.

It is also evident that the shield or clasp may be made of any form of outline, as round or oval or other ornamental configuration, and the ornaments of any configuration may be cast on the face of the shield, as desired, or according to the taste of the maker.

I am aware that heads have been formed on ordinary pins by the process of casting them in molds on blanks of wire having roughened and tinned ends but I claim The process of making a safetypin which consists in casting a shield or clasp on a blank or pin and then bending said blank, at or near the center, into a spring having one or more turns or coils, so that the point of the pin may be sprung into the shield or clasp, substantially as described.

JOHN P. COURTNEY.
