, Stair-Carpet Pad; and'I do hereby declare that thefollowing, taken in' connection with the. drawings which accompany and formpart of this specification, isa description of my invention suflicient to enable those skilled in Thetread of persons in traveling over flights of stairs differs from the tread of the same persons when walking upon alevel, the foot'descendin'g with a forward thrust or push, which bringsa peculiar wear upon the carpet of the "stairs, and calls for apad or.cushion under the carpet which will resist the thrusting'or pushing action of the foot.

Where mere layers of soft material are placed beneath the stair-carpet .on the treads of the staircase, they are soon displaced or pushed from the front edge of the tread of each stair, and are apt to become ridgy, leaving the carpet without a yielding wear-saving'cushion at the point of greatest wear-the edge of the stair-tread."

To obviate the objections named,and to pro- 'duce a stair-carpet pad whiclrwill not become ridgy, and which is impervious to moths and* dust, is the object of my invention. Said invention is embodied in a pad larg enough to cover that surface of a stair-tread which is overlaid by a carpet, when prepared as an article of manufacture, fit to be sold in any quantity, and ready to be applied without cutting or fitting.- It is coiistructed of one or more composite layers enileloped in a closed case oftextile material, t] s and the layer or layers inclosed being uni ed by quilting or sewing through the whole material, and the layer or layers, consisting of sheets of felt or batting or other fibrous matter, covered on each side with sheets of paper.

The drawing represents, in cross-section, my

improved stair-carpet pad, it being, shown as haying two layers of fibrous material, I), laywonld soon become ridgy. 'ing-layer, co-operatin g with the paper at the ers of paper c, and strengthening-layers of textile material a.

The quilting or stitches by which the central parts of the underlay or pad are held. to-

gether are shown at d 01.-

Without the employment of the paper the pad would be too flexible, and the layers a of soft fibrous material, adhering to the textile cover or strengthening-layer, would be dis placed by the thrusts received in wear, and

The strengthenplace where the stitches are made, enables the stitches to be held more securely than would be the case were the layer a omitted. The stitches easily cut into and tear through the papers; but when the textile layer a-is added,the stitches have an extra layer into which to h0ld, makin g them lessliable to cut and injure the paper of the pad.

Upon removal of a stair-carpet, thesepads beneath it may be taken up and cleaned by beating, and can he relaid with a change of position.

The strengtheninglayer a rests upon and contiguous to the layer of paper.

I claim- 1. As a new article of manufacture, a s'taircarpet pad constructed of one or more layers of fibrous material, covered outside with sheets of paper, and strengthening material outside of and next to the paper,the whole being quilted through all the materials composing the pad, substantially as described.

2. The fibrous material b and sheets of paper 0 above and below the fibrous material, combined with a strengthening-layer next the paper to receive the stitches which unite the paper and fibrous material, to prevent the j stitches cutting into the paper a, substantially as described .GEO. WV. OHIPMAN.
