MANSFIELD J. COOK, OF SYRACUSE, ASSIGNOR OF ONE-FOURTH TO SIDNEY H. COOK, JR, OF CAMILLUS, NEW YORK.

CARPET-STRETCHER.

SPECIFICATION forming part of Letters Patent No. 435,920, dated September 9, 1890.

Application filed November 15, 1889- Serial No. 330 473 (No model.)

To all whom it may concern:

Be it known that I, MANSFIELD J. COOK, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Carpet-Stretchers, of which the following, taken in connection with the accompanying drawings, is afull, clear, and exact description.

This invention relates to the class of carpet-stretchers in which the carpet-engaging bar is movably connected to a bar provided with a spur engaging the floor, and a lever is employed to draw the carpet-engaging bar toward the aforesaid spur; and the invention consists in an improved construction and combination of parts which form a carpetstretcher which is simple and compact in construction, and convenient, efficient, and durable in its operation.

The invention is fully illustrated in the annexed drawings, in which Figure 1 is a side view of my improved carpet=stretcher. Fig. 2 is a top plan view of the same. Fig. 3 is a perspective view of the carpet-engaging bar, and Fig. 4 is aninverted plan view of the ratchet-bars.

Similar letters of reference indicate corresponding parts.

A represents the bar or plate which engages the carpet to be stretched. This bar I form of a wooden plate A, in the under side of which are secured a series of pins or teeth adapted to engage the carpet. To the top of this wooden plate is securely fastened a metal 3 5 plate A which is preferably made to extend over the entire length and width of the wooden plate, and is formed with upwardprojecting guides at a, disposed transversely thereon and equidistantly from the center of the length of the plate. Said guides are formed with overhanging lips a a, for the purpose hereinafter explained. Said metal plate is also formed with an upward-proj ecting tooth 1), between the aforesaid guides and 5 having an elongated engaging'face standing lengthwise of the plate or at right angles to theline of the guides. In these guides slides a bar B, formed with longitudinal side flanges n at, over which the aforesaid lips a a project, and thus prevent the bar 13 from being lifted completely off from the plate A". There is, however, sufficient room under the said lips to allow the bar to be lifted suffi-= ciently to release it from the tooth b, which it engages by ratchets 0 0, formed on the un- 5 5 der side of the bar B. The front end of the latter bar has affixed to it a downward-projecting spur c, by which it is adapted to engage the floor. The bar B is also formed with upwardly-projecting ears (Z d and with a longitudinal slot f, which is central between the ratchets 0 0, and extends between the aforesaid ears. To these ears is pivoted a lever l, to the lower end of which is connected a ratchet-bar e, which slides longitudinally in the slot f, and is adapted to engage and release the tooth b.

The described carpetstretcher is operated by pressing the spur 0 into the floor in advance of the edge of the carpet to be stretched, and the bar A is slipped back on the bar B and placed upon the carpet. Then bythrowing the lever l forward the ratchet-bar e is pushed rearward, and in swinging the lever rearward the said ratchet-bar engages the tooth b and draws thereby the bar B forward, and the latter draws with it the underlying carpet. If it is necessary to further stretch the carpet, the lever Z has to be again thrown forward to carry the ratchet-bar 6 back to ob- 8o tain a new hold on the tooth 1). During this movement the ratchets 0 0 of the bar B engage the tooth b, and thereby retain the carpet-engaging bar A in position.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-= 1. A carpet-stretcher composed of a carpet-engaging bar, a ratchet-bar mounted movably longitudinally on the aforesaid bar and 0 adapted to engage and release the same and provided at its front end with a spur adapted to engage the floor, a lever pivoted to said ratchet-bar, and a ratchet-bar connected to said lever and adapted to engage and release 5 the carpet-engaging bar, substantially as set forth and shown.

2. The combination of the carpetengaging bar A,provided with the guides 01. a and tooth b, the ratchet-bar B, slidinglongitudinally in too site sides of the slot, the lever Z, inserted between said ears and pivoted thereto,and the ratchet-bar e, sliding in the slot f and connected to the lever, substantially as described and shown.

In testimony whereof I have hereunto signed my namet-his 12th day of November, 1889.
