SAFETY-PIN.

Specification of :Letters Patent. Patented Sept, 29, 1914,

Application filed April 3, 1913. Serial no. 758619.

To all whom, it may concern v 1 Be it known that I, FREDERICK C. SCOTT, a subject of the King of Great Britain, residing at Hornby Island, in the Province of British Columbia and Dominion of Canada, have invented a new and useful Safety-Pin, of which the following is a specification.

The invention relates to improvements in safety pins. p

The object of the present invention is to improve the construction of safety pins, and

to provide a simple, inexpensive and effi-Q clent safety pm of strong and durable conj struction, equipped with means adapted without weakening the pin proper or interfering with the ready passage or insertionof the same through a piece of fabric to inter lock the said pin with a coacting catch or keeper and prevent the safety pin from be ing pulled open under a fair amount of strain.

With these and other objects in view, the

invention consists in the construction andv novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention. T

In the drawings :Figure 1 is a perspective view of a safety pin, constructed in accordance with this invention and shown closed. Fig. 2 is a longitudinal sectional view on the line 22 of Fig. 1. Fig. 3 is a transverse sectional view on the line 33 of Fig. 1. Fig. 4 is a side elevation partly in section, one side of the catch or keeper being cut away. Fig. 5 is a plan view of a portion of the safety pin, illustrating the arrangeable material, comprises in its construction a movable bar or pin proper 1 and a relatively fixed side or bar 2, connected with the movable bar or pin by a spring coil 3 and carrying a catch or keeper, which is connected with the relatively fixed side by a transverse end portion 4. Thecatch or keeper which consists of'two lengths of wire spaced apart to allow for the introduction of the movable bar or pin proper, is composed of inwardly extending approximately U-shaped loops 5 and 6, located at the free end of the catch or keeper and constituting jaws and adapted to frictionally engage the movable bar or pin proper 1 at. opposite sides thereof, and the :said loops 5 and 6 extend from one side of I the safety pin and terminate short of the op- ;posite side of the same. formation of the catch or keeper is extended 'longitudinallyof the safety pin from one terminal of the end portion 4 in substantial The wire in the parallelism with the relatively fixed side or bar 2, and is then bent to form the loop 6,

which is connected at the outer portion with the loop 5. The wire is then extended back to the end portion 4, the connectingportions I7 and Sextending from the loops 5 and 6 to the end portion 4 are spaced apart and form a guard for the spaced end portion of the pin or bar 1. The terminal portion 9 of the wire is twisted around the end portion 4.,

stiffening and thickening the latter opposite the point ofthe pin, the stiffened and thickened portion cooperating with the spaced connecting portions 7 and 8 to prevent the hand or other portion of a person from coming in contact with the pointed end of the pin or bar 1 when the safety pin is closed The loops 5 and 6, which are disposed in substantial parallelism with the end portion 4:, have spaced sides or engaging portions, and theyare laterally offset from each other to arrange the coactingengaging sides or portions of the two loops in transverse planes arranged at different angles to the movable pin or bar 1, as clearly illustrated in Fig. 2 of the drawing. The movable pin or bar 1 is provided nearits pointed end with a bent portion 10, having spaced bends and a substantially straight intermediate connecting portion disposed at an angle to the inner portion of the pin or bar and off- Setting the outerpointed portion, thereof from the longitudinal ,plane of the inner portion. The coa'cting sides or gripping pertions of the loops engage the pin or bar 1 at I l the said spaced bend and securely hold the said pin or bar 1. The short substantially straight angularly disposed Connecting portion ofthe bend 10 forms a shoulder for I bend 10. The loops converge toward their ends 11 and 12', which are diverged or bent in opposite directions to form a flaring entrance 13 to facilitate the easy introduction of the pin between the clamping jaws, which frictionally grip the pin and hold the same in its engaging position. The offsetting bend 10 while interlocking the pin or bar 1 with the catch or keeper does not weaken the former or interfere with the ready insertion of the pinthrough a piece of fabric. I

The lateral offsetting bend may be extend: ed in either direction, and in Fig. 6 of the drawing, the bend 14 extends in the opposite direction to the bend 10 and the loops 15 and 16 are arranged the reverse of the loops 5 and 6. I \Vhile it is preferable to "form the catch or keeper and the guard. of

a single piece of Wire, any other equivalent construction may, of course, be employed for coacting or interlocking with the laterally bent pin.

What is claimed is 1. A safety pin including a movable bar or pin proper provided with spaced bends and asubstantially straight intermediate angularly disposed connecting portion 'ofisettingthe outer portion ofthe' pin from the planelof the inner portion, and a'catch or keeper extending from a *relatively fixed portion of the safety pin and having spaced coacting gripping portions arranged in pairs which are spaced apart longitudinally of the safety pin to engagethe movable pin or bar at the saidjbends thereof.

2. A safety pin including a movable bar or pin proper provided with spaced bends and having a substantially straight intermediate angularly disposed connecting por tion offsetting the outer portion of the movable pin or bar from the inner portion thereof, and a catch or keeper extending from a relatively fixed portion of the safety pin and comprising spaced coacting gripping portions arranged in pairs, the Mild pairs of gripping portions being disposed in transverse planes arranged at different angles to the movable pin or bar and engaging the same at the bends thereof.

3. A safety pin including a mo able bar or pin proper provided with spaced bends and having a substantially straight intermediate connecting portion offsetting the outer portion of the movable pin or bar from the plane of the inner portion, and a catch extending from the side of the safety pin at which the movable pin or bar is arranged and terminating short of the opposite side of the safety pin, said catch consisting of a pair of substantially U-shaped loops having spaced sides or gripping portions, the sides or gripping portions of one loop coaeting with the sides or grip iiing portions of the other loop and the coacting gripping portions or sides being arranged in dilierent transverse planes and engaging the pin or bar at the bends thereof.

A safety pin constructed of a single piece of wire and including a movable bar or pin proper having its end adjacent to the point deflected laterally and ofl setting the point of the pin or bar from the remaining portion of the same, and a catch or keeper composed of two lengths of wire spaced laterally to allow for the introduction of the pin or bar and formed at its free end with gripping portions arranged in pairs, which are spaced longitudinally of the pin or bar so as to engage the same at two points along the deflected portion thereof.

In testimony that I clann the foregoing as my own, I have hereto afiixed my signature ;in the presence of two witnesses.
