DOUBLE POINTED PIN FASTENEB Filed July 3, 1950 V Boden and George A. King, No. 17,100, both ,P atent'ed Dec. 30, 1930 ems-Dmm PATENT OFFICE KING, OF WATERBURY, CONNECTICUT, A SSIGNOB. TO SCOVILL MANUFAC- lIURING COMPANY, OF WATERBURY, CONNECTICUT, A CORPORATION OF CON- Application filed .Tuly 3,

' and has special reference to means for retaining thev shell or a cap in predetermined p ion up n the p n. 1 J j The double-pointed pins referred to are ofthe type disclosed "by the reissue patents of George, Boden', George A. King and Lyman B. Chapman, No. 17,099, and George dated October 9, 1928; and the shells or caps I may take a variety of forms asindicated by the use to which the be put.

The object of the invention is to provide means on the shell or cap for positiveengagement with predetermined portions of the pin, whereby the shell or cap is rigidly attached to the pin-and its accidental separation therefrom or displacement relatively pin fasteners are to thereto prevented.

The invention consists in a pin fastener,

"comprising a double-pointed-pin and a shell or cap. The pin has two legs bentto provide and joined by a U-shaped shell-engaging portion or bend arranged in substantial parallelism with and spaced from the legs, the spaces between the U-shaped portion and the legs forming at the bends provlsion'for the reception of cooperative retaining means carried by the shell or cap, and the shell or. cap

thus held in fixed position on the pin, as will be hereinafter more particularly explained and finally claimed. y

In the accompanying drawings lllustrating the invention, in theseveral figures of which like parts are similarlydesignated, Figure 1- is a rear perspective view of a shell or cap provided with an embodiment of retaining means in accordance with the invention. Fig. 2 is a view similar to Fig. 1, but showing a double-pointed pin arranged for assembly of the shell or cap upon it. Fig. 3 is a rear per- :spective view of the completely assembled pin fastener. Figs. 4 and 5, are, respectively, a front and a rear elevation of the pin fastener of Fig. 3. Figs. 6 and 7 are, respectively, a front and a rear elevation-of a pin fastener embodying the featuresof the invention, the

shell or cap of which is of the type to form the socket member of a separable fastener. Figs. 8 and .9 are, respectively,a front and a rear elevation of a pin fastener embodying the features of the invention, the shell or cap of which isof the type to form the stud member of a separable fastener.

As her'einbefore indicated, the tenor, nomatter which of the variousforms illustrated, or other conceivable forms, it may'take, includes a double-pointed pin 1 and a shell or cap 2. I

QThe double-pointed pin 1 comprises two pointed pinlegs 3 joined by a U-shaped shell-engaging portion 4: which, as illustratedin Figs. 2 and 3, is bent into substantial spaced parallelism with the pin legs 3 throughout its side portions 5. The legs 3 and. side portions'5. are joined and spaced apart by-bends- 6. q

The shell .or cap 2 has a face portionv 7 provided with an offstanding or rearwardly extending marginal flange 8, and this flange carriespin-engaging means in the form'of a bifurcated extension 9 which provides two deformable fingers10 for engagementwith the double pointed pin 1 at its bends 6.

I The length of the U-shapedshell-engaging portion 4'fromitsjoining bend to the bends 6 is such that it will fit snugly within the flange 8 and preferably in three point contact with it.

.. In assembling the shell or cap 2 upon the pin:1, the pin is arranged as illustrated in Fig.2 with its U-shaped portion within the flange 8 and resting upon the rear of the face portion 7 of the cap. Then, by the use of appropriate'tools, the extension 9 is depressed and its'fingers 10 so deformed and diverged laterally that they extend into the spaces between the legs 3 and the side portions 5 of the U-shapedportiOn 4 and preferably in intimate engagement with the inner surfaces of the bendsS, as illustrated particularly in Fig. 3. Then a small section of the edge of the flange 8 is bent to form a depression in overlapping engagement with the bend of the U-shaped portion 4, as indicated at 11.

7 pin fas- I rigidly held in'predetermined fixed relation thereto; 7 l

Although in Figs. to inclusivethe shell I or cap 2 is shownas a plain cap, it is obvious that it may take the form illustrated in Figs. r 6 and 7 in'which an opening'12-isprovide'd to formthe socket member ofa separable.

' fastener,'such as is disclosed in and covered 7' by fmy eopending-g application Serial No. .165,669,'filedFebruary3,1927; This opening [12 permits a complemental stud. to engage with the side portions '5 of thepin with a resilient or snap action.

fAlso, instead of the formsof'shell or cap 7 just referred to, the shell or cap maycarry the, studfmember afseparable fastener, as shown inFigs'. 8 and 9,:and'substanti'ally' as disclosed in tlie patentof Panl E. Fenton, No..1,647,962, dated November 1,1927.

If desired,anyflor all ofthe caps may be provided with a withdrawal-preventing prong ltseeFig. 9) which "will, in addition, functionally replace the de ression 11 of the.

edge of the flange Sof the cap. 7
