GLIDER FOR FURNITURE LEGS AND THE LIKE.

To all whom it may concem: 1

Be it known that I, EDWARD B. CARTER,

a citizen of the United States, and resident of San Francisco, county of San Francisco,

and State of California, have invented a new and useful Glider for Furniture Legs and the like, of which the following is 5 specification.

My invention relates in general to socalled gliders for furniture legs and the like and has reference more particularly to an improved cushion glider, so tospeak, which will perform its intended use with the greatest of eiiiciency, and overcome the disadvantages experienced with devices heretofore employed for this purpose. One of the important salient features of the invention resides in the means for cushioning the glider so that the furniture to which it is.

attached will noiselessly glide over any'kind of floor surface or floor covering without wrinkling or tearing the same and with the cushion feature absorbing all vibration and rendering the device a practical solution of 96 the problems involved.

Theinvention possesses further features,

, some of which will be referred to in the following detailed description .of the accompanying drawing, which illustrates the proferred embodiment of the invention.

In said drawing, Figure 1 is a viewjn elevation of'the lower end of furniture leg or the like illustrating the application of the invention; Figure 2 1s a vertical section on as the line 2-2 of Figure 1; Figure 3 is a view in. elevation of the insert with the :attaching prongsand showing the cushion in section, and, Figure 4 is a bottom plan view of the cushion.

Referring now to the drawing in detail, A may represent a chair leg or any other leg or supporting structure for portable furniture or the li e, and B represents the glider as applied-thereto. According to the preferred construction of the glider, I ro-- vide an insert 0 which is made of stee or any other suitable material, with integral attaching prongs (5), preferably three in' number, projecting upwardly from the an- .nular band (6) thereof with the' prongs made so that they do not have to be bent in the position shown in Figure 3, which will strengthenthe structure since the prongs do not have to be bent, which would be likely to leave themweaker at the points (7) where they are joined to-the band. The band (6) in reality is an annular wall for the cup-like structure of the insert and the lower periphery of the insert is crimped, as

at (8), to leave a rounded annular flange on the bottom of the insert so that the same may be practically embedded in the cushion a (9) which preferably comprises a rubber cup-like structure made with an annular bulge (10) around its circumference with the internal diameter of the same made to fit snuglyaround the insert, including the flange (8) and the band part The bottom of the cushion (9), which is preferably made of rubber .or some other suitable material having substantially the same qualities as rubber, is made with a series of bosses, as

'best' shown in Figure 4, so that when the 9 steel cap (12 is clamped or crimped over the cushion 9) the bosses will permit the cushion to be compressed without squeezing the material of the cushion out of the cap (12) or otherwise distorting it so that it will occupy the entire space within the cap and make a neat, tight fit. bosses (11) annular grooves or channels may be made in the bottom ofthe'cushion which will serve the same purpose as the bosses, or any other means may be resorted to to leave the cushion free to assume its compressed shape when the cap is clamped or crimped around the same.

As best shown in Figure 2, the inturne edges of the open top of the cap (12) press inwardly around the top of the cushion preferably at the termination of the bulge 10 where itjoins the perpendicular side ,13 of the upper edge of the cushion. This construction is arranged so that the cap (12) may be securely fixed in place and 6 at the same time leave a protruding annular extension (14), (see Figure 2) of the cushion, 'the'same being of substantially the same height as the band 7 (6) so that when I the prongs (5) are embedded in the funni- Instead of the so ture leg or the like the edge (14) of the .cushion will bear against the leg. The anthe cap (12) at all points, thus as only the cap (12) comes 1n contact with the floor there is no vibration actually created. It is also to be noted that the inturned edge of the opening in the cap extends over the.

cushion (9) beyond the diameter of the crimp (8) of the insert which accounts for a positive clamping of the cap in place and prevents any possibility of the cap. working loose. g m

I claim nrany advantages for this type of glider, for instance, there is nothing to wear out about it, it will not grip the floor, it will glide. easily and -noiselessly over any kind ,of a floor surface or floor covering and will defeat any possibility of the furniture being overturned, such for instance when used on chairs. There is nothing about it to rattle, or any friction parts which may squeak. These and many other advantages may be realized by the use of the device, and at the same time it is simple in construction, cheap to manufacture and easy to apply.

I claim:

1. A device of the class described comprising an insert member having upstanding attaching means, a part made of cushion material adapted to cover .said insert memberfand a cap adapted to be clamped tightly around said cushion material substantially as and for the purpose described.

As a new article of manufacture, a

glider for furniture and the like legs, in-' cluding' inner and outer members with a cushioning material between the two, said cushioning material serving to completely insulate said inner and outer members and having a portion to contact with the article of furniture and support the same out of contact with the outer memben:

3. As a new article of manufacture, .a glider for furniture and the like legs comprising an inner cup shaped member having upstanding means adapted to be embe ded in the end of the furniture leg, a

cup shaped cushion surrounding said inner of the upper extremity of the cushion to leave the edge of the cushion protruding above the said cap;.whereby it maybear against the bottom of the furniture leg substantially as and for the purpose described.

5. A glider for furniture legs, comprising acap-shaped metallic member, a cushioning member within the cap, and held therein by contracting the rim of the cap, said cushionin member having a shoulder projecting a ove the rim of the cap, whereby to support the leg of the furniture out of contact with the cap, and means carried by the cushioning member for attaching the device to the furniture leg.

6. A glider or tip for furniture legs, comprising a metallic bowl-shaped cap, a cushioning material therein, a metallic member resting on the cushion and held in place by the rim of the cap, and fastening means carried by the metallic member for connecting the cap to the furniture leg, said cushioning material serving to insulate said cap and metallic member and having a portion projecting above the cap for supporting the furniture leg out of contact with said cap.

7. A glider or tip for furniture legs, comprising a metallic bowl-shaped cap, a rubber cushion inserted therein and having a rim projecting above the rim of the metallic bowl, a cup-shaped metallic member resting on the rubber cushion and having a flange at its base whereby the rim of the bowl may be crimped inwardly to a diameter less than that of the flange, so as to lock the parts together, and means carried -ing turned inwardly and terminating short by said metallic cup-shaped member for at-
