CHAIR-TIP.

SPECIFICATION for`ming part of Letters Patent No. 698,228, dated April 22, .1902.

Application nea ruig? s, 190i;A

T0 all whom, it may concern: I Be it known that I, GEORGE C. Soorr,a citi-Y zen of the United States, residing in Boston,

in the county of Suolk and State of Massachusetts, have invented certain new and useful Improvements in Chair-Ti ps, of which the following, taken in connection with the accompanying drawings, is a specification.

My invention relates to devices for preventing chairs and otherarticles of furniture from defacing finished floors and for diminishing the noise when moved from place to place.

Of the various kinds of chair-tips which have been put upon the market those having a facing of rubber are at this time most used; but rubber hardens with time, vand thereby loses it resiliency, it wears away rapidly or else it disintegrates andis soon ruined by pieces breaking off, and it is also likely to become deformed, sothat it does not cover the projection to which it has been attached or causes the piece of furniture to Set insecurely or unevenly on the floor. .To remedy these defects, I have devised a tip that protects the floor and also serves as a 4yielding buffer for the supports ofthe chair, the article, moreover, being madevof materials that maintain their characteristic features and that are also cheap.` 'v

The invention consists in a resilient or yielding material forming a cushion and a facing of material suited to protect the cush-V ion and the floor, together with a fastening passing through or about the cushion and niture.

I have found by continued experiments that sole-leather will retain its shape, that it doesnot harden, has some cushioning effect, and is in all respects better adapted for a facing material for tips than any substance I have yet tried. As a substitute I sometimes use ber' of various kinds, which furnishes an efficient facing. Of the various substances which have suggested themselves to me for an intervening cushion or yielding medium the best results have followed the use of thick close felting, as this substance retains its properties without deterioration under the usual conditions of use. As a subseriti nu. 67,483. (No modem' spring-washers; but the best metal for'this purpose is steel, and this rusts in time and may stain a finished licor.

The drawings show in Figure l a stool having my tips applied; Fig. 2, an enlargedsection of a leg and a tip; Fig. 3, an enlarged section of a leg and a tip with adilferent facing;V

Fig. 4, an enlarged section of a leg and a tip with a different cushion.

In my preferred'construction I form the facing a of my chair-tip of sole-leather, the outer edges being chamfered to prevent uneven Wear and to present a finish. A holeb passes through the piece of leather and at the .face thereof it is counterbored to receive the head of the nail c, which may rest against the seat d of the facing. The nail is passed through the hole h of the facing and driven into the leg e of thelstool, and between the facing a andthe end of the leg e l put a piece of thick felting to form the cushion f,'the nail passing through a hole therein to hold it in place. The facing and the cushion may or may not be cemented to each other, my usual practice being not to secure the same together, as if each is free to move there'is more opportunity of even Wear of each part.

Sometimes instead of the piece of leather for the facing I use apiece of ber g, and in such cases I put a washer hbetween the head of the nail c and the seat d, as the head o f the nail may wear into the seat of the facing when made of suchv material. In place of material like felting for a cushion I sometimes use washers t', stampedl from spring- "metal and bulged outward, as cushions, and

vin Such cases it is usual to put a bearing- ,plate j on the facing ct and a similar plate k with the head of the nail received in said oounterbored portion of the faeing-blool{,si1l) stantially as described.

2. Achair-tpcomprisingoutwardly-bulged apertured spring-Washers, and an apertured facing-block, the Washers being interposed between the chair-leg and the facing-block with means passing through the facing-block and Washers and engaging in the chair-leg, substantially as described.

3. Achairtipcomprisingoutwardly-bulged apertured spring-Washers and an apertured faeing-blook with the bulged portions of the Washers contacting with one another and haw ing their opposite faees contacting with the facing-block and the chair-leg with means for seen ring:r the Washers and facing-block to the chair-leg, substantially as described.

In testimony whereof I have hereunto subscribed my name this 5th day of July, A. D. 1901.
