SPECIFICATION forming part of Letters Patent No. 703,965, dated July 1, 1902.

Application filed April 4, 1902. SiiaINo. 101,415. (No model.)

To all whom/aft ntayconcern: i

Be it known that I, EDwARp MQQONNELL, of Richmond, in the county of Henricoand State of Virginia, have invented-certain new and useful Improvements in Safety-Pins and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to' the accompanying drawings, which form part of this specification.

This invention is an improvementin safetypins of the kind illustrated in my Patents No. 406,367, dated July 2, 1889, and No. 590,622, dated September 28, 1897.

'The body and pin of my patented pin were made in one piece, the body member being formed of a close spiral coil of resilient wire, a few bends at one end being of larger diameter than the main body of the coil to'form a keeper for the pin-point. The other end of the coil was tapered toLa poi-nit,"fr'omljwhichi extended an integral rod-,- whic h was bent back to form the pin member. The obje'c tions to these pins are that it is difficult to make a properly-proportioned durable safetypin, because the wire strong enough for a large pin would be too stiff and large for the coils, or vice versa, and, again, it is difficult to properly temper such pins so as to produce a strong stiff pin with a sufficiently-pliable body. Another practical objection to the use of the patented pin was the diffioulty experienced in inserting the pin-bar through stiif material, the flexibility of the smaller end of coil preventing a firm grasp on the pin-bar, and light materials would crowd into and catch between the convolutions of thecoil at the base of the pin or smallenend-of-the coil, making it difficult and annoyingtoi'disengage the pin therefrom. The pres'enti'nvention' overcomes all these objections and at the same time improves and facilitates the construction of the pin and enables the pin-rods to be tempered properly independently of the coils anda sufficiently-stiff pin-rod-to be used withany desired diameter 'of'wireinthe coilbody.

The novel featuresof the invention upon whichproteotion is desired. are set -forth in the claims, and the followingdescrip'tion of the improved pin illustrated in the accompanying drawings will impart a clear understanding thereof.

. comple te pin. -tion therethrough. 'fFig. 3 is a longitudinal sectionshowin g a slight modification thereof.

In said drawings, Figure 1 is a view of the Fig.2 is a-longitudinal sec- The pin member B is formed separately from the body member. It is pointed at one end b ,-but its other end is preferably enlarged, the enlargement being preferably conical, as shown atb', and adapted to fit closely within the smaller end of the body A. Such pin jmemberiis'slipped point first through the bodymember'from'the large to the small end thereof and drawn outward until enlargement Z) binds tightly in the reduced portion a of the body. Then the pin member is returned toward the end a of the body member, forming therewith a complete safety -pin. The end 6 of the pin member fitting snugly against a plurality of coils at the end a of the body member makes the pin immovable and imparts a solidarity to the end a of the body member, which enables the user to get a better hold on the pin and more easily force and directit through thick materials. If desired, the ends 0. b may be wiped or dipped in solder to securely-unite them. After insertion of .the pin'in the material the part a of the bodyis-grasped'and' pulled outward, as indi- "'c'ated in dotted lines in Fig. 2, until the point of'the pin can enter the keeper a, formed by the larger convolutions of the coil. If it be desired to stiffen the body member, the pin member B may be formed, as shown in Fig. 3, with an extension or bar 12 inrear of the enlargement b, which extensionwill liewithin the coil and limit lateral movements or bending thereof. The superior constructionand advantages of the improved-pin over that shown in my said forth above, and r What I claim as novel, and desire to protect hereby, is

1. A safety-pin comprising a body member patent are sufficiently set formed of a coil of wire having a pin-point retainer near one end, and a pin member having one end fitted and secured to a plurality lutions of the body member at the end opposite the keeper, and its outer portion returned toward the keeper, substantially as described.

3. The herein-described safety-pin consisting of a pin member and a body member, the body member comprising a coil of wire surrounding a straight bar, said bar and coil be- I in g unattached except at the end opposite the shield, as set forth. 7

4. A safety-pin comprising a body member formed of a coil of Wire having a keeper at one end, and a stifiening-bar extending within the coil, and a pin member having one end fitted and secured to a plurality of convolutions 01": the body member at the end thereof opposite the keeper, and its outer end re-.

turned toward the keeper, substantially as described.

In testimony that I claim the foregoing as my own I affix mysignature in presence of two witnesses.
