IMPRO'VEMENT IN STAIR-ROIDS.

The Schedule referred to in these Letters Patent and making part ofthe same I, WEBSTER M-` CLAYTON, of New York, inthe county of New York, and State of New York, have the following is aspeciiication.

My invention relates to that class of devices for attaching a carpet toa stairs known as stair-rods .and

It consists of an ordinary concave-convex bar provided with slides which are partly concavo-convex and partly rectangular. Said slides embracing the concaveconvex rod, and carrying serrated dogs, which, on forcing a screw through the slide and rod, expands the serrated dogs, forcing them into the tread and rise between the rod and the `stairs,) to theV stairs, as I will further explain `by reference -to the drawings, of which- V Figure 1 is a front vewplof my improved stair-rod;

` Figure 2, a view ofthe opposite side,-

Figure 3, a` sectional View (on an enlarged scale,) showing the application of lnyiln'ention to the tread `and rise ofa stairs;

- Figure 4, an edge view ofthe slide;` and Figure 5, an edge view of the serrated dogs.

In the said drawingsi A indicates the concave-convex stair-rod, provided with circular holes B B for reception'of bracing-screws C C. l i i 1) D are the slides which embrace the stair-rod and fitting the convex surface of the rod, project inward into the angle formed bythe tread and rise' ofthe stairs, forming a support for the rod. (See iig. i

These slides receive and carry the expansive serrated dogs E E. Said dogs being united by hinges ff, both slides and dogs are provided with circular holes for reception of the bracing-screws C C.

lo' attach a stair-carpet to a stairs, I place the end of the carpet at the rst step, under the hall carpet, and I nail both down. I next partially strain the carpet over the steps, and I now place the stair-rbd over the carpet in the angle formed by the tread of the first step and riser of the second, and I turn the bracing- `screws C G forward, when the screws wil] bear against uthe serrated expansive dogs E E, forcing their serrated ends C into the tread and rise of the stairs, straining the carpet to the desired tension, and -iirrnly at -taching the carpet to the stairs, this operation being `but'tlle work of a moment; while to detach the stair-rod from the stairs, I merely reverse or draw the screws a little backward, when the serrated .dogs will lose their hold on the steps, and the rod can bel ref moved from the stairs.

That I claim is- Y The slides D D, rod A, screws C C, and expansive serrated dogs E E, combined, arranged, and operating substantially as and for the purposes described and set forth. l

In testimony whereof I hereunto set my signature this 12th day of February, 1870. l
