JEFFERSON D. MILLER, OF NEW YORK, N. Y.

STAlR-CARPET HOLDER.

sPECI'FIGATION forming part of Letters Patent No. 745,220, dated November 24, 1903.

Application filed April 4, 1903. Serial No. 151.186. (No model.)

To all whom it may concern.-

Be it known that I, JEFFERSON D. MILLER, a citizen of the United States, residing at New York city, in the State of New York, have invented a new and useful StairOarpet Holder, of which the following is a specification.

This invention is an improved construction of stair-carpet holder or fastener, the object being to provide a cheap and simple device by means of which the stair-carpet can be securely fastened at the angle formed by the juncture of the riser and tread.

Another object is to provide a stair-carpet fastener in which the parts shall be adjustable, so that the fastener can be made to accommodate different thicknesses of carpet; and a still further object is to provide a staircarpet holder or fastener which can be used as well upon curved steps as straight ones; and a still further object is to providea carpet holder or fastener which can be quickly and easily attached to or detached from the steps and also one which can be applied or removed without the aid of skilled'labor.

With these various objects in view my invention consists, essentially, in the employment of two angular metallic plates, one plate.

being connected to the riser of the step and the other plate to the tread of the step, each plate being provided with a serrated or toothed edge,said serrated or toothed edges projecting toward each other and adapted to engage the carpet which is forced therebetween, the portions of the plate contacting with the riser and tread being slotted, said slotbeing enlarged at one point sufficiently to receive the head of a screw, so that the plate can be attached to or detached from the step without removing the screws.

The invention consists also in arranging the slots obliquely, so that the plates can be adjusted toward or away from each other in order to accommodate various grades of carpet.

The invention consists also in making the strips narrower and providing them with ears, each ear being slotted in exactly the same manner as the plate, this construction of fastener being particularly adapted for use in connection with curved steps.

The invention consists also in certain details of construction hereinafter fully described, and pointed out in thelclaims; v

In the drawings forming part of this specification, Figure 1 is a perspective view showing the practical application of myinvention, the balustrades of the stairs being omitted in order to more clearly show the invention. Fig. 2 is a face View of one of the holder or fastener plates, the screws being shown in section. Fig. 3' is an edge view showing the relative positions of the plates when connected to the riser and tread of'the stairs. Fig. 4 is a detail face view of the fastening-plate particularly adapted for use in connection with curved steps. Fig. 5 is a top plan View showing the manner of applying said plate.

In carrying out my invention I employ a thin metal plate A, which is bent longitudinally along the line A, thereby providing two portions A and A the portion A being secured to the riser or tread of the step, so that the portion A will extend obliquely away from the said riser or tread, as most clearly shown in Figs. 1 and 3, and the outer edges of the portions A are toothed or serrated, as shown at A so that the stair-carpet, which is forced down between the toothed edges of the plates, will be securely held by the said teeth engaging the fold of the carpet forced between the'saidtoothed plates, and'no other fastening means will be necessary to secure the carpet at this point. The portions A of the'plates A are secured to theriser and tread of the steps by'means of screws B, said screws passing through the slots 0 produced in the saidportions A, and it will be noted that these slots are arranged obliquely or at an angle with the edges of the plate, and the bottom edge of the slot has a notch 0 produced therein of such a size that.

the head of the screw will pass freely therethrough, and thetop of theslot has a series of notches C of a size convenient toreceive the shank of the screw, as most clearly shown 5 IOO pying the central notches, and in case it should be desired to adjust the plates to accommodate a heavier grade of carpet the screws will be loosened and the plate moved to one side, so as to bring the shanks of the screws into the bottom notches whereas if a thinner grade of carpet is to be accommodated the plates will be moved so as to bring the shanks of the screws into the upper notches C In Figs. at and I have shown the construction I employ when fastening the carpet to curved steps and in which the plate A is made somewhat narrower than the plate A and is provided with integral ears A", which are bent at the same angle with the plate A as the portions A and A Each ear A has an oblique slot 0, which is arranged and operates exactly the same as the slots in the portion A This form of fastener bends easier; but its operation is identical with the fastener shown in Figs. 1 and 2.

In operation the screws are set at the proper points in the riser and tread of the steps. The plates are then arranged and the screws tightened. The carpet is then folded and inserted between the toothed edges of the plate, and is thus securely held. Should it be desired to use the fasteners for holding a lighter or heavier grade of carpet, the plates can be adjusted, as heretofore described.

By using expansion-spring bolts instead of wood-screws the plates can be connected to stone or iron steps.

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

1. Astaincarpetfastenercomprisinganangular plate, having a toothed edge, said plate having oblique slots, substantially as described.

22. A stair-carpet fastener comprising an angular plate, having a toothed edge, said plate having oblique slots, said slots having an enlargement upon the lower side and a plurality of notches in the upper sides, substantially as described.

3. A stair-carpet fastener comprising an angular plate having a toothed edge, said plate having ears, said ears having oblique slots, said slots being enlarged upon the lower side and notched at the upper side, substantially as described.
