` SAFETY-PIN.

mangas.

To all whom t may concern:

Be it known thatr I, JOHN I-I. FowLnR, a citiZen of the United States, anda resident of Orbisonia, in the county of Huntingdon and State of Pennsylvania, have madel certain new and useful Improvements in Safety- Pins, of which the following is a specicay tion.

My present invention relates generally` to safety pins, my object being to provide a safety pin of simple, inexpensive construction and having generally a greater capacity for connection of articles of clothing and the like than is provided by the ordinary safety pin now in use.

More particularly my invention aims to provide a safety pin 'having means whereby additional grip upon articles of clothing and the like to be connected is attained beyond that afforded by the ordinary safety pin or by any other pin whose connection with the clothing depends merely lupon the passage of a prong or pin member therethrough.

In carrying out these objects I provide a construction of safety pin to be hereinafter described with respect to the accompanying drawing and wherein-u Figure 1 is a plan view illustrating my improved pin with a flexibly attached keeper.

Fig. 2 is a vertical longitudinal section taken therethrough substantially on line 2 2 of Fig. i.

Fig. 3 is a view similar to Fig. 2 illustrating a slightly modified form of keeper.

`F ig. 4 is a plan view illustrating another modified form of keeper.

Fig. 5 is a partial longitudinal section through the forms shown in Fig. 4 and taken substantially on line 5-5 of said gure, and

Fig. 6 is a detail perspective view illustrating the guard carrying member of the keeper shown in Figs. 4 and 5. v

Referring now to these figures, my improved pin which is of the same construction throughout the several figures essentially comprises a pair of spaced parallel prongsv 10 bent at right angles vfrom and with respect to the head 11, the said prongs being.

sharpened at their forward or outer ends and having their rear or inner ends integral with the inwardly projecting rear side extensions 12 of the head 11, the latter of which has a forward cross bar 13 spaced forwardly from and generally parallel with the extensions 12 and projecting transversely across and overlying the rear portions of the Specification of Letters'llatent.

prongs 10 so that, by virtue ofthek integral conne.ction ofthe parts Aand theirforination from a single :section of wire as shownfthe naturalresihency Ithereof 4tendsto Aurge the cross bar 13 toward 'and against the .prongs .10), .thus farming. @1.9121512 fer engagement with the materialthrough which the Aprongs @tegendeel- .l A

In :this manner the maintenance lofl the safety pin 1n place inuse is primarily` attained by the clasping action of the cross barv 13 upon one or the other of the connected parts, or possibly both of suchv parts, the usual severe strain upon the keeper being in this manner relieved to aconsiderable extent.

In the present case the keeper may be of y various forms, for instance, in the nature of a rectangular frame 14 as seen in Figs. 1 and 2 having forward intermediate and rear cross bars 15, 16 and 17 respectively, it being noted that the frame so shaped is angular inv form, with its intermediate cross bar 16- in a plane above a plane yconnecting the forward and rear cross bars 15 and 16 so as tofrictlonally grip the forward sharpened ends lof the prongs 10 when projected therethrough in the manner shown in Fig. 2, the keeper so.

formed being attached to the cross bar 13 by means of a iiexible elastic connection 18 in orderto prevent its displacement, `and the forward `cross bar 15 havingan'upturned flange l19 therealong forming a guardin-advance of the pointed extremities of the prongs 10.

As shown tached to the cross bar 13 by a flexible elastic in Fig. 3 the keeper 2O isv atconnection 21 similar to the connection 1 8 f before described, but is itself constructed differently, being formed for instance `of wire with its intermediate cross bar 22 in a plane above a plane connecting its forward and rear cross bars 23 and 24 so as to firmly with. the arrangement extremities bent around the cross bar 13 as seen at 27 to pivotally `support thekeeperin position, the guard 26 consisting of depending angularly disposedl plates 28 and'29, the

forward of which is apertured to receive the` pointed extremities vof the prongs ythere through, and the latter of which has an intermediate upset portion 30 provided with a slit into which the pointed extremities of the prongs l0 are conned.

In either form, however, as before ldescribed the usual strain upon the keeper of a safety pin is obviated in accordance with the specific construction of the safety pin as provided by my inventionand it is to be understood for this reason vthat further modifications and changes may be made in the keeper or guard portion of the device at least, kwithout avoiding the invention.

I claim:

A safety pin comprising a pair of spaced parallel prongs and a head disposed at right angles to the prongs at the rear ends thereof, said head being in the 'form of a laterally elongated loop having rear inwardly projecting extensions integral with the rear ends of the prongs and having a forward cross bar overlying the prongs adjacent the rear ends thereof, and a keeper having means to frictionally engage the free ends of the prongs, said keeper being ieXibly connected to the said cross bar of the head.
