SAFETY-PIN.

SPECIFICATION forming part of Letters Patent No. 403,607, dated May 21, 1889. Application filed May 14, 1888. Serial No. 273,784. (No model.)

To all 1.0710711, it may concern.-

Be it known that we, EMILE PICKHARDT, of Islington, county of Norfolk, and State of Massachusetts, and DANIEL A. CARPENTER, of New York city, in the county and State of New York, have jointly invented a certain new and useful Improved Safety-Pin, of which we declare the following to be a full, clear, and exactdescription,reference being had to the accompanying drawings, forming part of this specification.

This invention relates to in'iprovements in the well-known safety or diaper pin; and the invention consists of a safety-pin whose shield is constructed and combined with the other parts of the pin, substantially as herein described and claimed.

In the accompanying sheet of drawings, Figure l is a side view of the pin; Fig. 2, an edge View showing the passage-way for the point; Fig. 3, a view of the wire portion of the pin; Fig. 4, a section in the plane a a, Fig. 1; Fig. 5, a plan of the shield-blank.

Similar letters of reference indicate like parts in the several figures.

Safety-pins provided with shields into which the pointed member of the pin is guided from either side are well known. This invention is an improvement in pins of that particular class.

The two limbs 1 and 2 and coil 3 do not diifer materially from the corresponding parts of other pins. It is considered desirable, however, that the outline of the pin should be made somewhat more tapering near the ends than is ordinarily the case, for the sake both of the pins appearance and convenience in operating it. At the end of the limb 2, opposite to the coil, the wire is bent toward the limb 1 into the figure of a hook, 4, the limb itself being either straight or curved between the coil 3 at one end of the pin and the hook 4 at the other. The shield is preferably drawn up from a flat blank and swaged or soldered to the wire. The blank has substantially the shape shown in Fig. 5 of the drawings, and on being submitted to the action of proper dies is formed into a shield having the faces 5 5 united to each other across the curved end 6 and along one edge, 7, of the shield, while the inner edge, 8, and a portion, at least, of the edge 9 are left open. In attaching the shield to the wire the hook 4 is inserted between the faces 5 5 and pressed snugly against the inside of the curved end 6, and the part of the limb 2 adjacent to the hook is brought nearly or quite even with the edge 9, and thus caused to lie either in or directly in front of the opening in that edge, this opening being made wide enough to allow the pointed end of the pin to pass through it on either side of the limb 2. Thus the pointed end of the limb 1, on being bent over against the limb 2 and allowed to move along that limb, but kept always in contact with it, is bound to enter the shield, no matter on which side the pointmay be presented, and it can of course leave the shield as well on one side as on the other.

The outline of the faces 5 5 may be somewhat varied, but the inner edge, 8, should everywhere extend behind the point of the sharpened limb, so that the point can pass into and out of the shield only through the open edge 9, as described.

Having now described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a safety-pin, the combination of the sharpened limb 1, unsharpened limb 2, coil 3, and a shield formed from a flat blank having the faces 5 5 united at the edge 7 and the open. edge 9, said shield being attached to the limb 2, a portion of which is located immediately at the opening in the edge 9 of the shield and serves as a guide whereby the point of the pin is directed through that opening from either side, substantially as and for the purpose described.

2. In a safety-pin,the shield thereof drawn from a flat blank having faces 5 5 united across the end 6 and along the edge 7 and open at the two other edges, 8 and 9, said shield being secured to the pins unsharpened limb, which constitutes a guide wherebythe point is directed through the opening in the edge 9 from either side, substantially as and for the purpose described.

3. In a -safetypin, the combination of the.

sharpened limb 1, unsharpened limb 2, with the hook 4 at the end thereof, the coil 3, and a shield formed from a fiat blank attached to the hook 4, said shield having the faces 5 5 united at the edge 7, and the open edge 9, through which the point of the pin is directed from either side by a portion of the limb 2, substantially as and for the purpose described.
