UNITED STATES PATENT OFFIon FRANCIS O. CLARK, OF DES MOINES, IOWA.

IM PROVEM ENT IN CARPET-FASTENERS.

Specification forming part of Letters Patent No. 200,172, dated February 12, 1878; application iled J une 29, 1876.

To all whom it may concern:

Be it known that I, FRANCIS O. CLARK, of Des Moines, in the vcounty of Polk and State ofl Iowa, have invented an Improved Carpet- Fastener, of which the following is a specilication:

The object of my invention is to secure a carpet to a floor by means of permanentlyiiXed carpet-nails and adjustable and movable carpet-strips, in such a manner that the edge of the carpet andl the nails holding it will be concealed and the corners lled, and the room ornamented by a solid molding, that can be readily put down and secured and as readily released and removed to lift the carpet without the aid of any tools.

It consists in a novel manner of forming, arranging, and combining a wooden carpetstrip, a sheet-metal strip, and a carpet-strip keeper with a series of doubled-pointed carpettacks, all as hereinafter more fully set. forth and claimed.

Figure 1 of my drawings is a perspective view, illustrating the construction, application, and combination of the several parts compos ing my invention.

A represents the oor of a4 room; B, the base-board; C, the carpet covering the door. a a is a row of double-pointed tacks, permanently Xed in the ioor by means of a suitable setting device, in a straight line, about half an inch distant from the base-board B.

bis a wooden carpet-strip, having a longitudinal groove in its under side, corresponding with the row of tacks a, which enter its groove c.

d is a sheet-metal carpet-strip, corresponding in size and shape with the wooden strip b, which it covers. ff are lianges on the longitudinal edges of the sheet-metal strip d, designed to lap over the corners of the wooden Strip b.

g is a metal keeper, conforming in size and shape with the metal strip d, over which it is placed to lock the complete carpetstrip into the corner. It has a straight head, h, at its top end, and an open eye or slot, d, in the top of the head.

k is an elbow-form screw or tnrn-button, that enters the base-board B, and serves to clasp the head of the keeper g rigidly to the surface of the base-board, and to thereby retain the keeper in proper position, as required, to hold down and lock the carpet-strip in its place, to

cover the nails and the edges of the carpet, and to prevent the carpet from slipping from the nails.

Fig. 2 is a section of my wooden strip b, having the groove c in its under side. They may be formed in any suitable manner, and vary in length and thickness, as desired. 'Ifhe groove c adapts them to fit upon the row of nails a in such a manner that the strip can be readily put down and taken up at pleasure.

Fig. 3 is a section of my sheet-metal strip d, having the flanges ff. These longitudinal flanges adapt it to be filled with the corresponding sections of wooden strips b, which readily slide in and out endwise.

Fig. 4 is a perspective view of my metal carpet-strip keeper g. It may be stamped from sheet metal by means of dies, or cast in molds.

Fig. 5 is a perspective view of my doublepointed carpet-tack.

From the detailed descriptions and functions of the various parts composing one of the complete carpet-fasteners, and the carpettacks which I use in combination with my carpetfastenin g devices, the manner of its use is obvious, and its novelty and advantages are apparent as a simple, complete, and convenient means of fastening carpets in rooms, halls, and 011 stairs.

I am aware that a stair-rod fastener having a shoulder and an eye similar to mine has been used; but I consider that my form of keeper,.adapting it to fit over and clamp a carpet-strip in the manner described, is a new and valuable improvement.

I claiml. The wooden carpet-strip b, having a longitudinal groove, c, in its under side and near its central line, adapted to receive and engage a row. of pointed carpet-holding nails, a, fixed in the ioor, in the manner shown and described.

2. The series of fixed carpet-nails a., the

combined wood and metal carpet-strip b d,

having the groove c, the keeper g, .and a revolving screw, k, arranged and combined to operate substantially as and for the purposes shown and described.

. FRANCIS O. CLARK.
