IMPRO'VED TIP FOR CHAIR-LEGS.

To all whom it may concern:

Be it known that we, EDWARD OooenN and How- ABD MILLER, of Washington city, in the District of Columbia, have invented new and improved Tips or Terminations for Chairs; and we do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to rnake and use the same, reference being had to the accompanying drawings, in which--` Figure l is a sectional elevation of a portion of the leg of a table or other article of furniture having our improvement attached thereto.

Figure 2 is a sectional elevation of a portion of the post or leg of a chair, showing our improvement, and the manner of attaching it thereto.

Figure 3 is a bottom view of the leg of a chair or other article of furniture, showing the tip in position.

Similar letters of reference indicate corresponding parts.

This invention relates to tips or terminations ofthe legs or posts of chairs and other'articles of furniture; and it consists in providing such legs or posts, at their lower extremity', with a glass or metal tip, for the purpose of preventing injury to the carpets upon the iioors of dwellings, as well'as the doors themselves, when no glafipets are used, as will be more fully explained here- A, in the drawings, represents the leg or article of furniture, which may be of any desired form or material.

B is a tip or-terminus of the post, which tip may be of glass, or of steel, or iron, polished upon its outer surface, to facilitate the moving of the article, and to prevent injury to the surface upon which it moves. This tip is made -convex upon its upper surfaces, the greatest amount of convexity being upon its upper surface, for the purpose of enabling it to fit into a concavity formed in the end of the leg or post, as shown in the drawings, while 'the outer or lower surface is only so much convex as to permit it to slide freely upon the carpet or floor of the apartmentI in which it may be placed. v

In constructing this tip, we give preference to glass as a material, not only because of its cheapness, but because of the fact that its surface is less likely to become roughened by use.

O is a bolt or socket, having, upon its inner end, pro- Liections, at right angles to its body, for the purpose of securing it in the material of which the tip is composed, where it may be placed, when the tip is cast or moulded, when made of any material which at the time assumes a liquid or semi-liquid form, but when inserted in other kind of substances is to be held by a screw,

or by suitable cement forced into the recess made to receive the bolt or socket. Upon the outer end of this bolt an eye is formed, for the purpose of receiving the shank D, which secures it to the leg or post.

D is a piece of metal, of any suitable form to pass through the eye in the outer end of bolt C, and en ter the recess or chamber E formed in the post, for the purpose of securing the tips B to such post.

This piece of metal may be of wire, as shown inthe drawing, or it may be a rod of metal, having a loop or eye in its outer end, to engage with the eye in the bolt or socket, C, and upon its inner end a disk or cross, arm, around which the cement is to be packed for thel purpose of retaining it in the recess.

E is a recess or chambeu'formed in the post or leg of the article to be furnished with our improved tips, for the purpose of receiving the shank or rod which secures the posts in position, which is to be dlled with any suitable cement, (such as chalk and glue, mixed in the proper proportions to form a paste or cement of the right consistency,) and into which such shank is to be forced, and which, when dried, secures it firmly therein.

F is a piece of rubber or other elastic material, which is to be placed between the inner convex surface of the tips and the outer concave surface of the leg or post, and is for the purpose of permitting the tip to turn slightly in its seat, and upon the joint formed bef,

tween it and the shank D, so that as the chair or other article of furniture is moved from a vertical position, as is frequently the case with chairs especially, the tendency to draw or extract the tip from its socket will be nearly if not quite avoided, and at the same time the tip will be allowed to yield suihciently to permit it to pass freely over any obstruction with which it is likely to come iu contact while being moved aroundv the apartment.

Having thus described our invention,

What we claim, and desire to secure by Letters Patent, is-

l. A tip for chairs and other articles of furniture, constructed substantially as shown and described.

v 2. The combination of the tips B, the elastic dividing-plate F,vand the leg or post A, substantially as and for the purpose shown and described.

3. The within-described method of seeming the tips to the legs or posts of furniture, it being by means of the shank D, the recessor chamber E, and a suitable cement. g

In testimony whereof, we have signed our names to this specification, in the presence of two subscribing witnesses. f
