SLIDING SHOE FOR FURNITURE.

Specification of Letters Patent.

Patented May 25, 1920.

Application filed May 12, 1919. Serial No. 296,296.

To all whom it may concern lie it known that l, Jenn AlioLPi-i JonssoN, a citizen of the United States, residing at the city of lVleriden, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Sliding Shoes for Furniture; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to sliding shoes for furniture but more particularly has refer ence to devices of this description in which the pintle inserted within the furniture leg has a rocking or oscillating connection with the shoe, the object being to preserve the flat contact of the shoe with the floor when the article of furniture is tilted or is moved over uneven floors or obstructioi'is such as rugs and *arpets.

The various features of novelty whereby this invention is characterized will hereinafter he pointed out with particularity in the claims; but, for a full understanding of the invention and of its objects and advam tagcs, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Figure 1 is a sectional elevation of the invention, showing the shoe made of a metal shell;

Fig. 2 a similar view exemplifying the inglass, porcelain, or earthen matter;

Fig. 3 a view similar to Fig. 2 but show ing the shoe having a reduced upper portion with which the cover plate is intcrlocked and an intermediate metal lining con fined between the cover plate and the top of the shoe, and

Fig. 4c is a sectional elevation showing a modification of the structure illustrated at Fig. 2.

Similar numerals of reference denote like parts in the several figures of the drawing.

Referring to Fig. 1, 1 is a flat bottomed base portion whose edges are curved upwardly as seen at 2, this base portion constituting the shoe proper and being formed of sheet metal.

3 is a cover plate whose peripheral edge 4 is interlocked with the upper peripheral edge 5 of the shoe and whose central portion is formed with an opening 6 which leads directly into a hollow portion t inclosed by said plate and shoe. 8 is a, p'intle extending near its lower end through the opening 6 and spaced therefrom and provided on its lower extremity with a rounded protuberance 9 which seats directly upon the bottom of the shoe, the diameter of said protuberance being greater than that of the opening 6 so that the pintle cannot be withdrawn.

Instead of forming the shoe of sheet metal it may be made of glass, porcelain or any other suitable composition, and therefore at Fig. 2 is shown a shoe made of any suitable composition other than metal and having a concaved upper central portion within which the head 9 extends and seats.

At Fig. 3 there is illustrated a similar composition shoe with a reduced upper undercut edge 12 with which the cover plate 3 is interlocked, and instead of forming the hollow portion 11 in concave shape a lining 13 is interposed between the cover plate and the top of the shoe, the lining itself where it enters the hollow portion 11 being concave to afford a proper seat for the protuberance 9.

The modification shown at Fig. 4 is similar to the construction shown at Fig. 2 eX cept that a converted protuberance 14 is formed at the central upper portion of the shoe while the enlargement at the lower extremity of the pintle has a concave lower surface that engages such protuberance, the cover plate being swelled upwardly as shown at 15 in order to provide the hollow portion 11. y

In all instances the lower extremity of the pintle has a rocking or oscillating contact with the shoe itself, and these constructions employ a minimum number of parts and are exceedingly eflicient and durable.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. In a sliding shoe for furniture a flat bottomed base having upwardly curved peripheral edges, a pintle having an enlarged lower end which latter has a convex face having rolling contact with said base, and

a cover plate through which the pintle extends, the cover plate having its periphery bent inwardly so as to interlock with the curved edges of the base thereby to prevent the cover plate from being disengaged from the base and to prevent removal of the pintle from the base, the base having a seat for said pintle end of greater diameter than said end whereby when the cover is removed the pintle can be lifted up out of engagement with the base.

2. In a sliding shoe for furniture, a sheet metal base of substantially uniform thickness having a flat bottom with flat upper and lower faces and having its periphery curved upwardly and outwardly, a cover plate seated on the upper edge of said curved periphery of the base and having its peripheral edge bent inwardly and interlocked with the curved edge of the base to prevent the cover plate from being disengaged from the base and to prevent removal of the pintle from the base, said base being formed to have the upper face of the bottom thereof provide a flat seat, and a pintle passed through the cover plate and having an enlarged convex lower end having rolling contact with the center of said flat seat of the base.

In testimony whereof I afiix my signature in presence of two witnesses.
