CARPET FASTENER.

Application filed April 10, 1924. Serial No. 705,656.

The object of this invention is to provide an improved socket member of a snap fastener for use especially oncarpets or rugs, for securmg the carpets or rugs in a smooth .and eflective way on floors, although thefastener is capable of use for other purposes or on other articles. 7

The invention consists of a socket member, having a relatively extended lateral base flange provided with attaching prongs and a central stud-engaging opening, preferably made resilient. the whole being made in one piece, as we will proceed now to explain and finally claim. 95 In the accompanying drawings illustrating the invention, in the several figures of which like parts are similarly designated.

Figure 1' is a plan view showing in dotted linesa piece of material, such as a floor covering or rug, to which the device is attached. Fig. 2 is an inverted view and Fig. 3 is a. cross-section of the fastener detached. Fig. 4 is a cross-section of the parts shown in Fig. '1. Fig. 5 is a plan view illustrating another form of the invention, and Fig. 6 is an inverted view, Fig? is an elevation and Fig. 8 is a cross-section of said modification.

Referring to the construction shown in Figs. 1 to 4. the flange 1 has its rim 2 turned in or rolled over, that is to say, reverted, and from the periphery of said inturned rim extend a number of prongs 3 normal thereto by which the device is attachable to an object, such as a carpet or rug. Inwardstud member, which may be of any usual or approved kind. The raised folded parts 5, 6 and 7 on the dome supply a reinforced stud engaging element, and being located on the dome are at the proper elevation to receive and securely engage the stud member. The folded parts 6 and 7 are located below the outer plane of the raised portion 4, and thus said raised portion serves to take the weight of persons treading on the socket member, and hence the parts 6 and 7 are protected from injury by such treading.

If the stud member is of the rigid or non-resilient type. then the stud engaging element of the socket member must be resillent, and it is so shown in the drawings,

, the resiliency being obtained by slitting the parts 5, 6 and 7 as at 9, so that the segments thus formed yield laterally for the passage, under applied force, of the head of the stud into and out of engagement with the socket. If the stud member is of the resilient type. then the stud engaging ele ment of the socket may be non-resilient, and so made by omitting the slits.

As already stated, one use of the device is as means for detachably securing carpets and rugs to floors, and the invention was particularly designed for securing rugs on the floors of motor vehicles, the socket being attached to the rug and the complemental stud member, usually in the form of a screw stud. being fastened in the door of the body. As shown in Figs. 1 and 4, the device is attached to the back 10 of the carpet, the prongs being forced through the back and by a suitable tool or other means curled over underneath the flange. When the flange has its rim inturned, the points of the prongs will, in the setting operation, be clinched against the inturned portion. as clearly seen in Fig. 4, so that there will be no unsightly appearance of metal to disfigure the face or pile 11 of the carpet; and inasmuch as the device is in one single piece, the socket may be applied very readily and in a very simple way. This form of the invention lends itself perfectly for use in setting or attaching machines having automatic feeding hoppers.

The form of the invention shown in Figs. 5 to 8 inclusive is the same in construction as that previously deSSEibed, excepting that instead of inturning the rim of the flange, itmay be left plain as indicated at 12 and the prongs 13 in this case will extend downwardly from the edge of the rim of the flange. This is a useful construction, but lacks the element of symmetrical finish and concealment of the points of the prongs inherent in the first described construction.

In both of these forms of the invention the central perforation or opening is sur rounded by a thrice-folded edge or rim which is the active agent for engaging the complemental stud member.

-As to both of these constructions, itis to be noted that each is a one piece fastener and hence there isa material increase in the facilityof production and a corresponding decrease in the cost. Furthermore, through i the contact of the carpet with the flat surface presented by the inturned edge. as shown in Figs. 1 to 4, the possibility of injuring the carpet from its underside. due to cutting or wear, is practically eliminated.

Both devices present a very durable and uniform snap action.

Variations in details of construction are permissible within the principle of the invention herein disclosed and in the claims fo lowing.

What we claim is -1. A socket member of a snap f stener. having a relatively extended lateral base flange provided with edge prongs and a central stud engaging opening surrounded b a series of infolded walls. the termin l wall being free and serving as the immediate stud engaging element, the whole being made in one p ece.

2. A socket member of a snap fastener. having 'a. relativel extended la eral base flange-provided with attach ng prongs and a central stud enga ing opening surrounded by a series of infolded walls. the term nal well being free and serving as the immed ate stud eng ging element. the whole being made in one piece, the said infolded Walls being slitted and thereby rendering the device resilient.

I 3. A socket member of a snap fastener, having a relatively extended flat lateral base flange provided with a reverted rim and prongs extending from the inner edge of the rim and adapted to clinch against the reverted rim in setting, and a centrally arranged stud engaging reinforced opening, the whole made in one piece.

4. A socket member of a snap fastener, having a relatively extended fiat lateral base flange provided with a reverted rim and prongs extending from the inner edge of the rim and adapted to clinch against the reverted portion of the flange in setting, and

a centrally arranged stud engaging rein-' forced opening, said stud engaging element depending from a dome-shaped portion, the whole made in one piece.

5. A socket member of a snap fastener. having a relatively extended flat lateral flange provided with a reverted rim and prongs extending from the inner edge of the rim and adapted to clinch against the inturned portion in setting, and a dome shaped portion having a central opening the edge of which is folded and the folded portion slitted.

6. A socket member of a snap fastener, having a relatively extended flat lateral flange provided with a reverted rim and prongs extending from the inner edge of the rim and adapted to clinch against the inturned portion in setting, and a domeshaped portion having a central opening surrounded by a thrice-folded stud engaging edge made resilient by slitting.

In testimony whereof we have hereunto set our hands this 7th day of April A. D.
