SLIDING-SHOE roa FURNITURE.

Application filed September 7, 1915.

for Furniture, of which the following is a specification.

This invention relates to sliding shoes for furniture, and its object is to provide a shoe or floor slide of this character made of glass, porcelain or other material adapted readily to slide upon a polished floor or carpet, and to which the fitting or spindle by which the shoe is attached to the article of furniture is rigidly secured.

Referring to the drawings which illustrate certain embodiments of the invention,Figure 1 is a side view of my improved device; Fig. 2 is a vertical, central section thereof, partly in elevation; Fig. 3 is a top plan view of the device; Fig. 4: is a vertical, central section partly in elevation, of the unassembled parts; Fig. 5 is a vertical, central section, partly in elevation, of modified form showing the parts unassembled; and Fig. 6 shows the device of Fig. 5 assembled.

In the form of the invention shown in Figs. 1 to 4 inclusive, the shoe or floor slide A is of glass or the like vitreous substance having a hard polished surface adapted to slide on the floor, and may have any of the usual exterior shapes or forms. It has a relatively wide central screw-threaded bore B adapted to receive a bushing G externally screw-threaded to engage said threaded bore, and internally screw-threaded to cooperate with and constitute a flatbottomed part of the threaded end D of the spindle or other fitting having a shoulder D upon which the leg of the article of furniture may rest, the spindle D entering and being rotatably held in the usual caster bore. The bushing C may be of wood or metal, although the former is preferable,

as less likely to crack or break the glass thread formed within the bore B. As large a bushing may be used as desired. The top of said bushing C is provided with a recess C adapted to receive the shoulder D of the spindle D when the parts are assembled, as best shown in Fig. 2, thus preventing the threaded end D of the spindle from com- Specification of Letters Patent.

ing in contact with the shoe and also adding strength tothe device. The fiat bottom of the bushing C rests firmly on the bottom of bore B. Spindle D, bushing C and shoe A are thus attached together against accidental separation.

lVhen the vitreous material used for the shoe or floor slide is of porcelain or the like, this material being tougher than glass, the bushing C may, as shown in Figs. 5 and 6, be dispensed with. As shown in said figures the shoe A has a central screwthreaded bore B adapted to receive the threaded end D of the spindle D and is further provided with a recess B into which the shoulder D is adapted to fit when the parts are assembled. It will be observed that in both of the instances shown the weight of the article supported is transmitted to the vitreous shoe by a lower relatively wide and preferably flat surface on, integral with or attached to the metallic spindle, and held firmly against and in wide contact with an upper surface of the shoe in use by a screw-threaded engagement. By this means the screw threads formed in the vitreous substance are not called upon to support any part of the weight resting on the shoe, and lateral strains can 'not result in moving the spindle or its attachment with respect to the shoe to result in cansing the weight of the furniture to rest on the shoe at a point, edge or mere line of the spindle. This is effective to avoid breakage of the shoe which, when attached at all to such a spindle, has not heretofore been avoided. If desired, liquid glue or a suitable cement may be employed to secure the screw or bushing in position.

A furniture support constructed in accordance with the invention above described can be economically manufactured and provides a simple, strong and eflicient means of rigidly securing the spindle to a shoe of glass, porcelain or the like.

I claim:

1. A furniture support consisting of a vitreous shoe and a fitting attached together, said shoe having an internally threaded bore, said fitting having a part comprising an externally-threaded portion and a relatively wide lower surface adapted to be held firmly against a relatively wide upper surface of the vitreous shoe by a screw-threadreous shoe having an internally threaded wide-bottomed opening therein and a fitting attached thereto, said fitting comprising a spindle having a shoulder and a threaded portion and a bushing having a recess and a threaded bore, the shoulder and the threaded portion of the spindle respectively entering and being in threaded engagement with the recess and threaded bore of the bushing having a lower surface fitting the bottom of said opening, said bushing having external threads adapting said bushing and shoe to be screwed firmly together with their said fitting surfaces in engagement.

Signed by me at Boston, Massachusetts, this 2nd day of September, 1915.
