IMPROVEMENT IN DlAPER-PINS.

Specification forming part of Letters Patent No. 106,422, dated August 16, 1870; reissue No. 6,69S, dated October 11, 1875 application tiled August 20, 1875.

To all whom it may concern; Be it known that l', lsaAo W. STEWART, of the city, county, and State of New York, have invented a new and Improved Diaper-Pin; and that the following is a t'ull, clear, and eX act description ofthe same, reference being had to the accoi'npanying drawings and to the letters of reference marked thereon, making a part ot' this specification. j

This invention is in the nature of an impins; and the invention consists in a safety-pin Yconstructed with the rear end of the wire forming the pin bent at or nearly at a right angle to the pin, and also in the diaper-pin, constructed with a series of eorru= gations, substantially in the manner hereinafter described.

In the accompanying sheet of drawings, Figure l is a plan of the blank which I use to Fig. 2 is the same when partially bent or shaped and ready for application to the wire. Fig. 3 is a plan of the shield when linished and attached to the wire. Fig. 4 is a plan of adiaperpin as' usually made before my invention; andl Fig. 5 is a side View, showing the angular bend of endot' nu. 1 Similar letters of' reference indicate like parts in the several lgures.-

Diaper or safety pins, as heretofore constructed, have had the shields A for the vpoint of the pin made by first striking up disks of metal in the shape ot' cups, then flattening them, and making aslot in the flattened side, and finally soldering' them to the unsharpened end of the wire, as shown in Fig. 4.

Ihis operation is not only7 slow, but expensive, and it is particularly objectionable, since the wire is attached to the side of the shield by solder, which not only makes an unsightly joint, but a weak connection.

' By my inventid these objections are obviated, for I construct my shields of hat blanksi shield or guard of a of metal, of the form shown in Fig. 1, or any.

other desired form, and by suitable dies the ends a. and sides b are bent, as shown in Fig. 2, and a series of corrugations', c, formed on the front side of the shield. The unsll'arpened end. of the wire B is bent at or nearly at a right angle, and this bent end d (which should be long enough to extend across the bottom of the shield, as indicated in Fig. 3) is inserted into the shie1d, and by means ot' swaging or otherwise 'the ends a and sides b of the shield are forced tightly in contact with the wire B and the bent part d thereof, holding the shield and the Wire of the pin firmly and strongly'in position. The' bentend d st-ilens the pin, making it firm at its point ot' attachment to the shield; and, besides, it offers more surface for the purpose of attaching it to the shield, whether in the manner just described or by solder, and the corrugations c stili'en and render strong the shield A, I

so that it may be made of extremely light metal.

Care should be taken to have the ends of the parts a to fall short of meeting when bent down. over the wire suiciently to leave an lopening, f, for the admission of the free point ot' the piu within the shield.

'Having thus described the construction of my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a diaper-pin, the unsharpened end of the pin, bent at or nearly at right angles, and extending across the bottom of Athe shield, and re-enforcing the same, substantially in the manner and for the purpose described.

2. In a diaper-pin, the shield thereof, being constructed with a series of corrugations, substantially as and for the purpose described.

.. I. W. STEWART.
