CARPETMSTRETCH ER.

SPECIFICATION forming part of Letters Patent No. 298,856, dated May 20, 1834.

Application filed November 22, 1883. (No model.)

2'0 @ZZ whom t may concern.-

Be it known that I, FREDERICK J. HUE- BARD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, -have invented a new and useful Carpet-Stretcher, of which the following is a specication.

My invention relates to improvements in carpet-stretchers; and it consists in a recessedl longitudinal bar and a retaining-case, with drop-pawl, which operate in connection with a hand-lever, provided with a yoke and a toothed bar to adjust and retain a carpet until it is fastened.

Similar letters refer to similar parts throughont the several views.

Figure I is a perspective view representing my device arranged to stretch a carpet. Fig. 2 is a plan or top view of Fig. I. Fig. 3 is a sectional part on the line y y, showing the inanner of retaining the bar e in position; Fig. 4, vertical view of my device folded up; Fig. 5, vertical view of the tooth used in bar a.

a represents a wooden draw-bar, armed with curved teeth b upon under side, designed to catch in the carpet when operating the device. The teeth b are formed square where they unite with the head b, which prevents their moving in the bar a when in operation. rI he point and portions of the teeth which come in contact with the carpet are rounded, as is shown in Fig. 5, so as to avoid tearing the carpet.

Loosely pivoted by the pintle a in the center of the draw-bar a, Fig. +L, is the retain ing-bar or case c, upon either side of which are the flanges d, for keeping within proper bounds a longitudinal sliding bar, e, in whose upper face are holes or recesses e. At one end of said bar is the spur or hook f, to be driven in the floor. At the other end .of the bar c is the projection g, which prevents the bar from coniing entirely out while in operation, the said bar being inserted in the retaining-case c previous to fastening the yoke referred to hereinafter.

7L is a hand-lever, the point of which engages with the recesses e. 'Ihe said lever has its fulcruni in the yoke z', whose ends are pivoted by pintlesj to standards 7c, on the upper edge ofthe iianges cl. The fianges dare united at one end by a strap, d, upon Whose upper surface are the lips Z, between which is held the drop-pawl m, by the pintle n.

With the exception of the draw-bar a, 1n device is preferably made of metal.

In Fig. 4, I show my device folded up-an advantage I gain in space or room occupied in shipping, and the niost convenient method of disposing of it when not in use.

The operation is as follows: After the carpet is tacked at one corner of the room, at the opposite side of the room, I drive the spur j' into the iioor and draw out the slide -bar c until the projection g touches the pintles of the yoke i'. I then attach the draw-bar a, by the curved teeth b, to the carpet, a little back from the edge. The short arm of the handlever 7L is then brought in contact with the recesses e', the handle end of the lever lying cen trally back in a position of about forty-five degrees from the horizon. The lever is then carried forward to a position nearly vertical or farther, which motion `will draw the slide-bar one recess in, and stretch the carpet that saine distance. If the carpetis not stretched enough, the operation ofthe lever is again gone through with, and so repeated until the obj eet is gained, the drop-pawl m holding the slide-bar e at each operation.

rIhe dotted lines in Fig. I indicate the 1noven1ents of the lever and connecting-yoke.

Vhat I claim as new. and desire to secure by Letters Patent of the United States, is-

l. In a carpetstretcher, the combination of the draw-bar a, having curved teeth b inserted therein, the case o, pivoted to said bar, the flanges d, the recessed bar e, provided with spur f and projection g, the handlever h, with yoke ,pivoted to standards, as described, and the drop-pawl m,secured as specified, all these parts arranged and operated substantially as described.

FREDERICK J. HUBBARD.
