The press four furniture glides for the chair are mounted punch 32, which has suitable central cavity 33 On these fl s 6, two at the front and two therein, is next forced downwardly thus spread at the rear. The glides are generally designated ing the legs 27 of the spider outwardly so that I! and being identical in construction and as- 55 their outer extremities are forced into tight enportion as seen in construction shown may shells peripheral retaining flange 23 as shown in Figure 8. The upwardly dished middle body portion 25 of the spider 20 thus forms with the downwardly dished middle body portion 22 of the outer shell, a generally spheroidal compartment 34 in which the rivets head 29 is freely movable. The shank 28 of the rivet is is likewise freely movable in the central aperture 25 of the spider, thus providing for a limited universal movement of the rivet relative to the outer shell and spider members.

The punch 32 is next removed, and the annular rubber cushion 2i is placed in position ad jacent the spider 20, circumscribing the rivets shank l9, and extending somewhat above the upper rim of the outer shell 18. The article of furniture is next placed in position with its flange i6 adjacent the upper surface of the rubber cushion 2| and with the rivets shank 28 extending upwardly through an aperture 35 in said flange it. The riveting head 38 of the press gagement with the outer is then forced downwardly as illustrated in Figure 9, said head first squeezing the rubber cushion 2| and then spinning over the upper end of the rivet is while the rubber cushion is squeezed between the article of furniture and the spider 2d of the glide. The parts are thus finally assembled.

It is to be particularly noted that after final assembly the rubber cushion 2i remains compressed or squeezed between the chair frame ii and the spider 29, and it thus normally urges the shell and spider of the glide away from the chair so that the rivets head 29 normally engages the underside of the spiders upwardly dished middle Figure 0, wherein the double arrows indicate the forces exerted by the cushion 2|.

It will be seen that when the chair is occupied, the dispiaceable quality of the rubber cushion permits universal movement of the chair and rivet relative to the outer shell and spider of the glide. The chair can thus be tipped rearwardly as indicated in Figures 4 and 5, while the outer shell iii of the glide remains in approximately the same position on the floor with its relatively flat middle portion contacting the floor. Thus the somewhat sharper curled edges or shoulders of the glide do not normally come in contact with the floor, and there is little likelihood of the glides making any impression in a composition or linoleum floor. This is particularly important with linoleum floors wherein too much mastic has been spread under the linoleum, as such doors are more readily indented and marred.

It will thus be seen that the invention provides a novel furniture glide having a unique limited universal movement relative to the article of furniture to which it is attached, for the purposes above described, and that the glide is of simple and rugged construction and attractive appearance. While but one specific embodiment of the invention has been herein shown and described, it will be understood that numerous details of the be altered or omitted without departing from the spirit of the invention as the same is defined by the following claims.

I claim:

1. The method of making a furniture glide and assembling it with an article of furniture, which method comprises: forming an outer shell with an upwardly and inwardly curled peripheral retaining hange; case-hardening said shell; placing a rivet in the shell with its head adjacent the center of the shell and its shank extending upwardly therefrom; forming a spider with an upwardly dished centrally apertured middle body portion and legs extending radially therefrom in downwardly-outwardly directions; placing the spider in the shell with the rivets shank projecting upwardly through the spiders central aperture; compressing the spider downwardly to spread the legs thereof into tight engagement with the shells peripheral retaining flange; placing an annular rubber cushion within the shell so that it circumscribes the rivets shank and so that its bottom surface lies adjacent said spider and its to portion projects above the upper rim of the shell; placing the article of furniture adjacent the topsurface of the rubber cushion with the upper end of the rivets shank extending through an aperture in said article of furniture; exerting pressure downwardly on the article of furniture to squeeze the rubber cushion between the article of furniture and the spider and at the same time riveting over the upper end of the V rivets shank to secure the parts in assembly.

2. The method or making a furniture glide and assembling it with an article of furniture, which method comprises: forming an outer shell with an upwardly and inwardly curled peripheral retaining flange; placing a rivet in the shell with its head adacent the center of the shell and its shank extending upwardly therefrom; forming a spider with an-u wardly dished centrally apertured middle body portion and legs extending radially therefrom in downwardly-outwardly directions; placing the spider in the shell with the rivets shank projecting upwardly through the spiders central aperture; compressing the spider downwardly tight engagement with the shells peripheral retaining flange; placing an annular rubber cushion within the shell so that it circumscribes the rivet's shank and so that its bottom surface lies adjacent said spider and its top portion projects above the upper rim of the shell; placing the article of furniture adjacent the top surface of the rubber cushion with the upper end of the rivets shank extending through an aperture in said article of furniture; exerting pressure downwardly on the article of furniture to squeeze the rubber cushion between the article of furniture and the spider and at the same time riveting over the upper end of the rivets shank to secure the parts in assembly.
