Application filed February 2, 1915. Serial No. 5,611.

T0 all whom t may concern Be it known that I, GEORGE C. SNYDER, a citizen of the United States, residing at New York, county of New York, and State of New York, have invented certain new and useful Improvements in Snap-F asteners, and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to fastening devices, and more particularly to snap fasteners of the threadless type.

Heretofore threadless snap fasteners, or, in other words, snap fasteners, the socket and stud members of which each comprises elements mechanically locked and attached to the fabric, have been limited in use to gloves, pocket-books, and similar articles, as the parts have never been so constructed as to stand the treatment received in laundrying.

It is the principal object of this invention to provide a snap fastener especially adapted for use on shirts, underwear and other articles which have to be laundried.

In furtherance of this and other objects which will hereinafter appear as the specification proceeds, the invention consists in the novel construction and arrangement of parts hereinafter described.

The invention is illustrated in the accom- Y panying drawings z-Figure 1 of which is a vertical section showing the parts of the socket member of the fastener in position ready to be assembled, together with a portion of the assembling mechanism; Fig. Q is a plan view of the spring member which is associated with the socket member in the manner hereinafter described; Fig. 3 is a vertical section through the spring member taken on the line 3-3 of Fig. 2; Fig. 4l is a. vertical section corresponding= to Fig. 1, representing the parts shown in Fig. 1 in the position which they assume at the completion of the down stroke of the plunger of the assembling mechanism; Fig. 5 is a vertical section through the socket member of the fastening device showing the socket member attached to the fabric and theparts thereof completely assembled or set, Fig. 6 is a vertical section through the stud member showing the same attached to the fabric;

Fig. 'l' is a similar view showing the use of a cap for covering the top of the stud member; Fig. S is a vertical section through the entire fastening device showing the socket -member applied to the stud member, or yotherwise stated, showing the stud member inserted in the socket member; Fig. 9 is an enlarged plan view of the stud member shown in Fig. 6; and Fig. 10 is a perspective view showing one strip of fabric having the stud members applied thereto, and a second strip of fabric having the socket members applied thereto.

Referring to the drawings, 4and particularly to Figs. 1, 2 and 3, the socket member consists of a head portion 1, which may be of any shape and size desired, as the specific construction of the head of the socket member is immaterial, so far as the present invention is concerned. Associated' with the socket member is a tubular shank portion 13 which is provided with a basal int-urned flange 11. As will hereinafter appear, this flange is adapted to be deflected and turned farther in toward the walls of the shank when the thimble hereinafter referred to is forced into and expanded in the tubular shank 13. A reinforcing collar 2 encircles the tubular shank 13, and is provided with a fabric-clamping flange 15. This portion of the socket member so far described may be supported on a suitable work table 3, of any assembling mechanism, when it is desired to attach the socket memberto the fabric. The fabric shown at 8 is then stretched over the opening at the base of the shank, as clearly shown in Fig. 1, and a metallic thimble 4c having substantially the cross section shown in the drawing is then forced into the shank 13 by means of the plunger 7 and the yielding portion 6 carried by the plunger. The thimble 4l, as it is forced into the shank 13, carries with it a portion of the fabric 8. Then the walls of the thimble pass the edge of the inturned flange 14C, a disk is cut from the fabric and is carried down with the thimble to the head of the socket member, as clearly shown at 16 in Fig. 1. Vhen the head of the thimble strikes the head 1, the walls of the thimble commence to collapse and expand radially to form a. bulbous head thereon, as best shown in Fig. 4.

The part 6 'of the plunger is yieldlngly mounted with respect to the part 7, so that after the thimble commences to collapse, a basal fla-nge 17 on the thimble may be forced into clamping engagement with the fabric,

flange ,15 on the member 2, and thehflange V17 on the thimble. forced into the shank 13, the fabricand -the thimble deflect they flange 11i and bend the same into closer proximity with 'the walls of the shank 13, as shown in Fig. 4. As the head portion of the thimble expandsradially in all l directions behind this flange 1i, it is obvious f that ythe thimble is firmly interlocked in the l interior of the thimble.

shank 13, ,and the fabric tightly gripped between the gripping flanges ofthe collar 2 and thimble @respectively Thiscollapsing action of the thimble behind the. flange 14 is substantially 'the same as thecollapsing action of the thimbles shown in my copending applications. Ser. Nos.' 8.1.4:34 and 847,938, filed June 11. 191i and June E29,

1914, respectively. In the present instance, however, the thimble t vhas associated therewith, a spring element 5 having a plurality of depending resilient fingers 1S,Y This spring element 5 is applied to the thimble as shown in Fig. 1, being (held in place by means of the peripheral turned-over portion 19 of the thimble. The spring element 5 is so positioned with respect to the thimble that the resilient fingers 18 project into the When the thimble collapses behind the flange 14, in the manner above described, the extremities of theV resilient fingers 1S will be slightly spaced from the walls of the thimble, as clearly shown in Fig. Lls. y,

The attached socket member' is shown in Fig. 5, the parts of which are'firml y locked i toeachfother and to the fabric.

The stud member may also be mechani-f cally attached to the fabric by the collapsing Vaction of a thimble, as exemplified in Figs.

6 and 7. The outer part of the stud mem` -ber may consist of a tubular cylindraceous element V10, also provided with a basal inturned flange 1i", similar to the flange 1% i ofthe shank 13. In Figs. -6 and 7, vhow- -ever,this flange is shown deflected intol close proximity with the' walls of the tubular *member\10, as the tliimble and fabric so deflect. the Lflange during theV assembling operation. The thimble is shown at 11, but` differs from the thimble il used for the socket 'me`1nber, as it is provided 'with no fabricclamping flange. Tlnsis to prevent any of vvthe'metal of the fastenei` from contacting 6d with the body, but obviously, a flange may "the fabric-clamping flange is omitted from the tli1mble,in the form shown in Figs. 6 and 7,'the`th1mble must bel so designed as:

als the thimble expands ybehind the flange ll, the fabric will be gripped between the walls of the thimble and the wallsof the `ring-like member 1,0. the fabric being tightly gripped between the The c vlindraceous stud member 1() is provided with a rounded flange Q0 for cooper- `ation with the resilient lingers 1S. as will hereinafter appear.

will, therefore, present a finishedappearance. lfL so desired,however, a cap or cover 19a-,of any appropriate material, may be formedv on or applied to the roundedllan `Then the socket member is to'beapplied to the Vstud member, the head ofthe stud member 'is directed into the opening of the socket member, and the two members pressed together, so that the resilient lingers 18 will engage with the vround-ed flange QO of the stud' member and yieldingly hold the two members together, as shown in Fig. 8.

it will be noted that the construction and arrangement the parts of the socket member is such that there is little vor no danger of injury to vthe partsduring laundrying ofthe fabriicto which the socket member vis applied. The resilient lingers` of the spring member project into the interior of the socket member and are, therefore, well protected. Furthermore, as the resilie fingers are not held under tension, as is the casewith the corresponding resilient means 'of former fasteners, there is no danger of Both the socket and stud members project y only a' small distance from the fabric, thereby lessening their-.liability to damage,

andnotwithstanding this fact, the parts are so constructedv that both the socket and stud members are firmly and mechanically attached tothe fabric. The neat and finished appearance presented by the socket and stud members of the improved' fastener is ap- .,parent'froinFig.10.

Obviously numerous changes andmodifications may bev made in the details of construction, as above described, without departing from the spirit or scope of the invention, as defined in the accompanying claims. j i
