I `This-*invention relates to tips for chair legs or the like, and more particularly to Vtips having a cushion for engaging the floor on f which the chairV orother articlev of furniture 5l is supported. y .i n y; p The objects vof thekinvention aretopr'ovide a simple "cushioned tip Y construction which can be cheaply andeconomically 'mani' ufaetured; toprovidea cushioned tip having means whereby the same may be mounted in the lower end of a chair leg or the like and.l

particularlyv inA the. lower `end of a tubular metal leg ,toprovide a tip which will Vnotbe likely to, scratch or otherwisefmar the Hoor `whichit engages, even after ythe cushion elef ment is worn away yto such an extentthat it no longer supports the load; to'provide a tip structure which canbe easily and quickly removed and replaced with a new' tip .when the first one becomes fworn; andin general, to provide an improved tip of the :class described.f K v ,z Other objects Y and advantages of the' invention will ber understood Vby reference 'to the following specification and accompany` ing drawing in which `Ifhave Ydescribed and illustrated a selected yembodiment.ofthe invention. w "i, I f

The cup-shaped member is `formed with Aan inwardly projecting annular flange portionf26' which is continued outwardly ,andrearwardly 'as shown'v at27, so as to forin a smooth, preferably convex, outwardp `v`ly facing bottomofedge or surface 28, and

also/so as to engage the lbase plate 11 as shownfat ,29. y preferably convex, but `smooth surface,

The bottom surfaee 28 is twill". be understood ,that when` ileg, kthe arms19iand20 are compressed toto establish the in the manu'f'acture free from sharp corners, will` be quite serviceable. The cup is secured in the recess preferably by being spot-welded to the bottom wall of the recess as shown at 80, and the cushion member24, preferably of compressible material, such as felt, is locked-in place in the cup' member in any suitable manner, for instance, by having a portion intermediateits inner and o uterends compressed by the inwardly projecting, annular flange 26. It will thus be seen that the cup member is securely fastenedin place in the recessv of the mounting member 10, and that the cushion member is releasably locked in the cup member.

It will be yapparent that when the cushion member wears down completely, the entire tip structure may be replaced by withdrawing the mountv from the chair leg and ref placing it with anew one, or the cushion element alone may beremoved from thecup part and a new cushion element inserted. It will further be noted that when the cushion member 24 wears down to the point where itno longer sustains Lany of the load of the article which it is` intended to 'support, the outwardly facing cornerless (free from sharp corners) edge 28 ofthe cup member will take up the load, Vand being smooth, as above described, will not scratch or mar the iioor or other surface on which it rests, even though the articlek which ity supports is slid across suchfsurface.

ln Figs. 3 LIl, 5 and 6, certain of the steps of my improved tip are shown. Fig. 3 is a section showing the lower end portion of the mounting member as it appears A before 'the recess 12 is formed therein. The mounting member is'initially formed with a convex over a fioor without scratching the same. Hence, my improved tip stri'icture includes an elementivhich of itself ,forms a complete and operative tip.

YFor changing this initial tip structure from the convex surfaced type to a cushioned tip. Iforce the convex portion 31 inwardly of the tip to form the recess 12 as shown in Fig. 4. A cup member having a bottom wall 32, side wall 33 and outwardly Aextending annular rim flange 34, is' then seated in the recess 12 and secured therein preferably by spot-welding the vbottom wall 82 of the cup tothe bottom wallof the recess-12; The portion ofthe wall 33 of the cup adjacent ,theV iiange'l is then s waged inwardly to form the inwardly proJecting annular' 'shoulder 2G as shown in Fig. 6

During this operation, thecushion member i seated in the cup, lf the cushion member is so seated, it will be obvious ,that the same will be interlocked with the cup when the annular shoulder 2 6 isifo'rmed therein, a portion of the cushion bottom surface 31, whichin itself is adaptedV to glide smoothly being compressed as shown at 35 during the formation of the said annular shoulder. After the shoulder is thus formed, the outwardly extending annular flange 34: is turned rearwardly of the cup into engagement with the base plate 11 ofthe mounting v member so as to form the outwardly facing rounded bottom face 28, as shown in Fig. 2.

If the cushion member 24; is not seated in the cup whenthe shoulder 2b is formed, Athe cushion may be inserted after the rounded face 28 is formed on the cup, the shoulder 26 being effective to sufficiently compress the cushion member to lock it in place.

The tip thus formed presents a neatappearanc'e, is strong and serviceable, and may be readily replaced when necessary; l

'lhe above described details o'f construction are merely illustrative'ofa single embodiment of the invention, for which reason vthe scopeof the Asinne should be determined reference to the following claims, which should be construed as broadly as possible consistent'with the state ofv the art.
