SPECIFIGATION forming part of Letters Patent No. 625,567, dated May 23, 18979. Application filed March 2. 1897. Serial No. 625;'735; (No model.)

To 'all whom t may concern.:

Be it known that I, Janus L. Knvofsromof Boston, in the county of Suffolk and State of Massachusetts, ,have invented an Improvement in Fasteners, of which the following description, in connection with the accompanying drawings, is a specification, like letters on a vertical sectional view-of my invention as form of spring-clip shown in Fig. l.

it may be embodied in a rug-fastener shown in place. Fig. 2 is a plan view of the fastener proper, Fig. 2 being a view in detail of the Fig. 3 is a` plan view of the stud to which in Fig. l the fastener is shown as applied. Fig. 4 illustrates a form of stud member adapted to be used when two layers of fabric are to be united, it being attached to one layer in position to cooperate with a housing member o'n the other layer, as shown in Fig. 1.

In Figs. l to 3, inclusive, I have shown the fastenerl as built up from sheet material and consisting, primarily, of an upper member centrally swaged or spun or otherwise raised above the plane d of attachment in which lies the dange or web-like portion of the blank of metal or other material from which it is made to form the housing fl",into which the head of the fastening-stud L may ent-er.

To engage the fastening-stud and hold the fastener firmly thereto, I have provided a clip made of a fiat spring F, (best seen in Figs. 2 and 21",) split throughout the greater part of its length and having the split enlarged at about the middle to form an attaching-aperture f, adapted to receive the head of the stud, the legs of the spring f and f2 coming into gripping engagement with the neck of the fasteningstud L, which preferably has, as illustrated, a groove l, into which the said legs enter, so that the head ZX of the stud pre*- vents accidental displacement of the springclip therefrom. As one suitable and strong means for securing-this spring-clip to the upper member I have shown the flat portion or web d of the latter as recessed in the in,`

. stance illustrated by cutting material "away at d2 to form a seat for the clip F, the headl nular plate h, extending entirely across the lower surfaceofthe upper member d, to which it may be affixed by crimping the edge of one over that of the other, as illustrated, or in any other suitable and desired manner. plate has a central aperture h opposite the aperture f of the clip and approximately of the same size as the latter, and it not only serves to hold the clip in place, but also to protect the latter by insuring proper relative position of the fastener and stud before the fastener can be forced down upon the stud.

It is often desirable to change the position of this class of device on the fabric, &c.', to which it is secured, and While fasteners are in existence which are merely sewed to the fabric and may therefore after removing the stitches be secured to another part of the fabric in a similan manner, and While my present fastener offers no obstacle to the use of suoli securing means, if itis desired to perforate its members slightly, as indicated at d4, Fig. 2, I have shown securing means which I believe to be novel and which afford means This j to readily and at any time enable removal by IOO a seater to receive and engage the threaded post h2. In applying the fastener to the fabric P the post h2 is forced up betweenthe fibers of the fabric at the desired spot until the end ap'- pears above the fabric,when the nut or equivalent device K is screwed or fastened down upon-it, fthe material of the fabric-in the region. of the device beingl clamped between the housing member and its securingmeans. Obviously upon unscrewing the nutthe operator can relocate the fastener where desired.

Whilel haveillustratedthe housing d' as rounded,it is-within the scope of 'my'invention to give it any convenient form, and instead of providing it with a post h2 it.may be furnished with a threaded aperture and the device K be provided with a threaded post tol enter the same.

It will be noted that the threaded opening in the nut, as shown in Fig. 1 which receives the threaded post h2 extends but .partially through the nut, so as 'to'leave the top of the latter smooth and free from depressions that would tend.` to collect dirt and be a general nuisance.

As a convenient` form of stud member I have shown at L an annular member adapted to receive in its central aperture a securingscrew or the like means, by which it inay. be fastened ,to the fio'or, dac., and having a neck contracted as described at l; but, however, my fastener may be used with any suitable form of fastening-stud.

Inasmuch as it is often equally desirable that not only the fastener, but the fasteningstud, may be adjustable upon the fabric, particularly Where rugs are used upon carpets, use may be made of any suitable stud adapted to be attached removably to the fabric. One form of such a removable stud I have illustrated in Fig. 4, where the upper memberm has a grooved head m and a central threaded recess m2, and the lower platen has a threaded post n to pass through the fabric 0 and enter into engagement with the threaded recess m2, whereby the fastening-stud is attached to the fabric, the latter being clamped between the plates. l

I do not restrict my invention to the exact contour shown, since the same may be varied considerably without departing froln the spirit of my invention'.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. Acarpetorrugfasteningdevice, consisting of a stud member adapted to be fastened to the floor or support, a housing provided with a spring-clip adapted to engage said stud member said housing being provided with a vertically-projecting post adapted to pass through the carpet or rug to be fastened, and

a holding member detachably arranged upon `said post for detachably holding the carpet or rug between it and said housing.

2. A carpet or rug fastening device, consisting of a stud member adapted to be fastened vertically-projecting threaded .post `adapted to pass through the carpet or rug to be fastened, and a nut partially threaded upon said threaded post for detachably holding the carpet or rug between it and said housing, the

. post receiving the 'threaded opening in said nut and extending but partially throughthe latter so as to leave the top of the nut smooth and free from depressions, for the purpose speciiied.

4. A carpet or rug fastener comprising a .spring-clip F of flat metal having a head f3,

and legs or grippingmembersf, j?, apertured-atj to receive a suitable fastening-stud' or the like; and housingorsupporting means for said clip, said means comprisingY a lower plate apertured to permit entrance of said fastening-stud, and an upper housing member having a central portion raised to clear said fastening-stud, and an integral hanged portion recessed to receive said clip; said plate and upper housing member `being secured together with said clip embraced between them; and means by which said fasten-er may be attached to a carpet or rug.

5. A carpet or rug fastener comprising a spring-clip Fof fiat metal having a head fs and legs or gripping members f', f2, apertured at f to receive a suitable fastening-stud por the like; and housing or supporting means for said clip, said means comprising a lower plate apertured to permit entrance of said fastening-stud, and an upper housing member having a central portion raised to clear said fastening-stud, and an integral flanged portion recessed to receive said clip; said plate and upper housing member being secured together with said clip embraced between them; and means by which said fastener may be attached to a carpet or rug; said means coniprisinga vertically-projecting post on said housing member and adapted to pass through the carpet or rug to be fastened, and

a holding memberarranged detachably upon y said post for holding detachably a carpet or rug between it and said housing.

In testimony whereof l have signed my name to this lspecification in the presence of two subscribing witnesses.
