CARPET-STRETCHER.

SPECIFICATION forming Ypart of Letters Patent No. 325,345, dated September 1, 1885.

Appliration filed May 1G, 1885. (No model.)

To @ZZ whom t may concern,.-

Beit known that I, Lnvr KRIEG, a citizen of the United States, residing at Frankfort, in the county of Clinton and State of Indiana, have invented certain new and useful Iniprovements in Carpet-Stretchers; and I de hereby declare that the following is a full, clear, and exact description of the saine, reference being had to the annexed drawing, making a part of this specification, and to the letters and figures of reference marked thereon.

The present invention has relation to that class ofcarpet-stretchers consisting of a board, cross-head, or other like device having upon its under side claws to enter the carpet, which is stretched by means of awindlass over which is wound a cord connected to the door by a hook attached thereto, the windlass being provided with ratchet-wheels with which engage pawls, and is operated by a pivoted lever having its end bifurcated and adapted to engage with the ratchets to turn the windlass.

The object of the present invention is to improve the above-mentioned class of carpetstretchers and simplify their operation; and it consist-s in forming the side arnis of the bifurcation ofthe lever with elongated slots,th rough which the axle ol' the ratchet-wheel passes, so that the lever can be raised in a true vertical line to disengage the dog in the bifurcation of the lever with the ratchet-teeth, also rendering the spring-paal adjustable to regulate its pressure upon the ratchet-wheel, as will be hereinafter more fully described and claimed.

In the accompanying drawing, -which represents a perspective view of niy in vention partlyin broken section, A represents the bar, of any suitablelength, having at its outer end the cross-head B, provided-upon its under side with spurs a.

To the opposite end of the bar A are two short standards, Z1, between which is mounted upon a stationary shaft, c, a ratchet-wheel, C, having around its periphery a central groove, d, for a cord or chain, e, one end thereof being attached to the wheel and the opposite end to a hooked rod, D, which passes through guides f in the bar and cross-head.

A lever, E, has a bifurcation at its lower end which straddles the ratchet-wheel C, the side arxns, g, of said bifurcation having clongated slots h, through which the axle c passes. The lever Ebetween the side arms, g, has a dog, 1?, to engage with the teeth of the wheel G, and back of said wheel isa spring-pawl, F, longitudinally adjustable on the bar A by thumb-screw k, which passes through an elongated slot, Z, into the bar. The end of the pawl F, as willbe noticed, is notched, as siown at m, to allow the cord, wire, or chain e to freely pass around the groove in the Wheel C without catching on the end of the pawl. The adjustability ot' the pawl F is to allow it being brought with greater or less pressure against the ratchet-teeth, or to bring it out of operative position.

In stretching the carpet theleverEis forced down until the dog t' will readily engage with the teeth on the wheel C, after which the n heel can be turned by the lever. The hook in the end of the rod D is driven in the floor, which acts as a fulcrum, and by turning the wheclin the proper direction the head B is forced forward with the carpet.

Then it is desired to disengage the dog i with the teeth in the wheel C, the lever is raised the extent. of theslots h. Thus the head B is free to be nioved forward to again take hold of the carpet.

The slotted side arms, y, oik the lever E are of importance, as they allow the said lever to be raised vertieall y to disengage the dog t' with the ratchet-teeth, and by a downward pressure again made to engage therewith, the slight vertical movement being all that is required ofthe lever to bring it in or out of operative position. The adjustability of the springpawl F is essential, as the pressure on the ratchet teeth is regulated to adapt the device in stretching carpets of different weights and thickness, where a greater or less leverage power is required.

Any suitable means may be employed for connecting the rod D with the wheel C-sueh as a rope, oord, chain, or wire-and any suitable material may be used from which to construct the several parts of the stretcher.

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

In a carpet-stretcher, a grooved ratchetwheel, a bifurcated lever having its side arms ICO formed with elongated slots, and o dog formed In testimony that I claim the above I have in the bifurcation to engage with the ratohethereunto subscribed my name in the presence Io Wheel, the axle thereof extending through the of two witnesses. slots and supported by standards, in combination with an adjustable spring-pznwl, a cord and hook7 and a bar and oross-head provided with spurs, substantially as and for the purpose set forth.
