SAFETY-PIN CATCH'l SPECIFICATION forming part of Letters Patent No. 258,792, dated May 30, 1882.

Application tiled April 8, 1882. (No model.)

To all whom 'at may concern:

Be it known that I, SAMUEL MOORE, ot Providence, in the county of Providence and State of Rhode Island, have invented a new Improvementin Safety-Pin Catches, and I do hereby declare the following, when taken in connection with accompanying drawingsand the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part ot' this specilication, and represent, in-

Figure 1, a perspective view; Fig. 2, a perspective view of the catch; Fi.g.3, aperspective view of the spring detached; Fig. 4, a transverse sectionon line x x; Fig. 5,a longitudinal section.

This invention relates to an improvementin catches used to engage and protect the point of the pin on brooches and other articles of 2o jewelry, safety-pins, Src., and particularly to that class ot' catches which are struck up from sheet metal into U shape, one leg forming the base for securing the catch, the other leg recessed upon the inside to receive and cover the point of the pin, and such as seen in Fig. 2, the object of the invention being to apply a spring in a cheap and simple manner, which shall close the recess made to receive the point of the pin, yield readily for the insertion of the pin, and prevent its accidental disengagement when properly inserted; and the invention consists in a U-shaped spring arranged within the U-shaped catch, one leg resting' upon the base, the other leg closing the recess on the opposite side, its end projecting to one or both sides, so that the end-of the pin pressed down upon the spring will open the passage into the catch for the entrance of the pin and close so soon as the piu is entered, as more fully hereinafter described.

As represented in Fig. 2, the catch is of the usual forni. It is constructed of sheet metal in substantially U shape, one leg, A, forming the base and usually flat, the other leg, B, struck into concavo-convex shape in transverse section, so as to form a recess, c, upon the inside, the connected end C also concave-convex shape in transverse section, substantially the saine as the leg B,

The spring, as seen in Fig. 3, is cut from suitable sheet metal, and bent into substantially U shape, one leg, D, corresponding to the base A, the other leg, E, so as to lie close against the inside of the other leg, B, or its end constructed with a projection, b, at one or both sides. The spring thus formed is placed between the two legs A B, as seen in Fig. 1, so as to bring the projecting ends b b near the end ofthe leg B, the projections b extending one each side, and so as to close the inner side oi' the recess in the leg B, as seen in Fig. 1. The spring secured in that position, the catch is ready for attachment to the body of the article, the pin being applied in the usual manner, and so that its end may come within the U-shaped catch. In catching the pin the point end is pressed upon one of the projections b until the spring is forced away from the leg B, as seen in broken lines, Fig. l, and so as to permit the pin to pass into the recess in that leg. Then the reaction ofthe spring brings'nit back again, so as to close and secure the pin within 'the recess, from which it is disengaged by reversing the operation. The spring is best secured in the catch by inserting the bend F, connecting the two legs into the end C of the catch, then closing the edges d of that part C of the catch down upon the bend of the spring, as seen in Fig. 4. By this method of securing the spring the use of solder is avoided, the leg d of the spring extending far enough onto the leg ofthe catch to form a firm bearingfor the, spring, so that very little strain comes upon the engaging-points d. This spring may be applied to good advantage in the better classes of safety-pins. In such case the leg A is extended to forni the body of the pin, the catch end B C being made substantially the same as shown.

I claiml. The U-shapcd catch A B C, the one leg, B, recessed upon its under side to receive the pin, combined with a correspondingly U shaped spring, D E, one leg resting upon the base, the other closing the recess, and provided with a projection, b, at its outer end upon one or both sides, substantially as described.
