2 Claims.

'I'he present invention relates to cushion slides for furniture, particularly of the type adapted to be attached to the furniture by driving with a hammer, an object being to provide such a slide ofI neat appearance, of simple and inexpensive construction, and which has resiliency characteristics adapted to provide resilient' and compensating support for furniture of widely different Weights. To this end it is proposed to provide resilient cushion means adapted to have a limited flexing under very light loads, providing the proper resilient support and compensation for irregularities within its limits, which also has normal liexing under relatively heavier loads, and which provides solid support under excessive loads. Another object is to provide a cushion slide which will permit tilting of the furniture without loosening, and which will at all times remain firmly in place, without looseness or rattling, irrespective of whether the slide is in engagement with the floor or not.

A further object is to provide yan interlocking connection between the floor engaging sliding shoe and the cushion element, which will reliably retain them together under all conditions of use, but which at the same time will permit of` convenient manual assembly and disassembly.

A still further object is to provide a slide which will be practically noiseless whenl being moved about, due to its ability to flex under very light impacts. It is still another object to provide a slide which will permit of the use of relatively harder rubber, or similar material, than could heretofore be successfully employed, thus providing a more reliable connection between the cushion body and the sliding base.

With the above and other objects in View an embodiment of the invention is shown in the accompanying drawing, and this embodiment will be hereinafter more ful ly described with reference thereto, and the invention will be finally pointed out in the claims.

In the drawing:

Fig. 1 is a side elevation of a cushion slide, according to the illustrated exemplary embodiment of the invention.

Fig. 2 is a top plan View thereof.

Fig. 3 is a view partially in side elevation and partially in vertical section of the resilient cushion element.

Fig. 4 is a vertical sectional View of the sliding shoe.

Fig. 5 is a side elevation of the attaching nail element.

(o1. usf-42) Y Fig. 6 is a'y vertical sectional view showing the slide attached to a furniture leg.

Fig. 7 is a similar 'View showing the position of the parts under light load.

Fig. 8 is a similar view showing a tilted position 5 of -the leg. o Similar reference characters indicate correspending parts throughout the several figures of the drawing.

Referring' to the drawing, the cushion slide, according to the present embodiment of the invention, comprisesv a circular cushion body III, formed of rubber or `othersuitable resilient material, provided about midway between its upper and lower surfaces with a vlaterally extending pel15Y ripheral groove II, the peripheral portion of the rubber body beneath this groove being of semicircular cross section and constituting a plug section I2 adapted for interlocking insertion in the sliding metal shoe or base, as will presently more 20 fully appear. 'A central vertical passage I3, for -the attaching nail, is provided in the rubber body and at its lower end thelower surface of the body isv provided with acircular recess I4 for receiving the nail head. A

The'upper surface of the body is provided with ai series of spaced concentric ribs I5, which constitute the light load flexing area, as will presently bemore 'fully explained.

' -The attaching nail I'isadapted to be snugly 3o engaged in the passage I3 andthe head I I seated in the recess I4, the depth oi' the latter being greater than the thickness of the head to provide a space within which the head may move during exing and tilting, the depth of the recess being 35 somewhat increased in the attached relation, as will be presently more fully pointed out.

The sliding metal shoe or base I8 is provided with an upwardly and inwardly curved rim I9 into which the plug section I2 is adapted to be 40 forced and expanded to thus interlockingly retain the parts together. In the assembled relation the upper inturned portion of the rim eX- tends into the groove II and provides an under support for the peripheral portion of the exposed 45 upper section of the cushion body. The inner wall of the groove II is inwardly spaced from the edge of the rim I9, so that the rubber section in the plane of the groove is laterally unconflned to a predetermined extent, and therefore permits free lateral expansion of the upper unconned portion I0 of the cushion body without cutting or restriction.

In attaching the slide blows are applied by 55 Y a hammer Vagainst the metal base i8, Y.and after the nail is driven to a point where the cushion body contacts the end of the leg further driving compresses the cushion element, so that upon its expansion after the driving operation the head of the nail presses the base of the recess I4 upwardly and assumes a position in spaced relation above the inner surface of thebase, the

cushion element being under slightcompression to maintain this relation andeliminate looseness and rattling, The section l5 'through its relatively increased resiliency permits this drivingV Vand positioning action of the nail toybe: accomplished with increased facility, particularly where a relatively hard rubber is`A employed.

The reduced crossesectional' area of the* upper ribbedV portion l5 and the air spaces between the ribs is such that thisl portion will compress toria substantial Vdegree under a relatively plight' load, so`that resilient support and compensation 'for irregularities is provided for light furniture which would otherwise not provide' sufficientV weight. to compress the main body of the rubber cushion. VAs shown in- Fig; 7 the ribs vexpand into the air spacesunder this ,condition- NormalY loads vwill compress the main body'of theA rubber l within Ypro-per limits to provide resilient support andY compensation for irregularities.V Extremely heavy loads will compress the rubber: only to the point where the nail head contacts the metal base, whereupon solid'support will. be provided,

` so that the rubber is thus relieved of excessive deteriorating pressure.

Fig. 8 illustrates the position of the partsrwhen Y VYreliable than when relatively soft rubber is employed.

I have illustrated and described a preferred and satisfactory embodiment of `the invention but it will be obvious that changesmay vbe made therein, within the spirit and-scope thereon as 'Y Vdefined in the appended claims.

Having Vthus described my invention what, claim and desire to'sevcurerby Letters Patent is:-

1. A cushion slide for. a furnitureleg comprising a, cushion body of rubber having an upper surface adapted to engage with the lower end of said leg, said cushion body'having a peripheral groove intermediate its upper and lower surfaces dening an upper resilient portion and a lower shoe attaching portion, said upper portion being provided with a series of recesses rendering it lessV resistant to deformation than said lower portion, a non-resilient sliding` shoeY having a substantially flat base and an upwardly and inwardly extending rim, the lower portion of said'cushion body being disposed in said shoe with the edge of saidv rim engaging said groove, the marginal portion 'of said upper portion overhanging said rim'andadaptedto be compressed between said rim andsaid leg, and leg attaching means carried by said cushion body, the relatively greater resistance to deformation of said lowerY portion Y being suchV that upon tilting of said leg relatively to said; shoe separation of said'srhoe therefrom through deformation of said' cushion body is prevented while saidupper Yportion is subjectV to deformation.

2.A cushion slide for a furniture leg compris.- ing a cushion body ofV rubber'having an upper surfacev adapted toV engage with the lower end Y of said leg, said cushion body having a peripheral-'groove intermediate its upper and lower surfaces deiining an upper resilient portion and a. y lower shoe attaching portion, a non-resilient sliding shoe having, aV substantiallygflat base and an upwardly and inwardly extending rim, the lower portion of said cushion body being Vdisposed.V in
