Thisinvention relates to a foot which is attached to articles of furniture, and it relates particularly to a rubber foot for chairs.

The objectof the invention is to provide a new and novel foot for chairs and the like, i which are provided with vtubular or other hollow legs.

"Another object is'to' provide a rubber foot for chairs which has a portion thereof ex- 39 tending up into the 1c of the chair, and which has means provided tin securely maintaining the foot in position.

A further object is to provide a rubber foot 'for hollow chair legs and the like, which has 115 a knob or head which abuts the end of the le which has a portion integral with the kno extending into the leg, and which is provided with tlghtening means for compressing the foot so that it will swell tightly inside of the at) hollow leg and hold the foot in place to prevent it from being accidently removed or lost."

the inner end of the foot, and it has struck up portions thereon to hold a nut and prevent it from turning during tightening of'the bolt.

The accompanying drawings illustrates'a selected embodiment of the invention and the views therein are as follows:

Fig. 1 is a perspective view of a chair having the improved rubber foot appliedto each leg thereof.

Fig. 2 is a detail view,-partly in section, showing the rubber 'foot applied to a tubular chair'leg.

Fig. 3 is a sectional plan View on the line 3-3 of Fig; 2.

Fig. 1 is a top plan view of the nut holding washer.

' Fig. 5 is a sectional view on the line 5-5 59 of Fig. 4.

Fig. 7 is a top plan view thereof.

Referring to the drawings, 10 designates any type of chair to which the invention may be adapted. The rear legs are pivoted to the front legs and stretchers 12 and 13 are connected to the front and rear legs respectively. The chair has a back 14 and a hinged seat 15, so that it may be folded up and stored away when not in use. l

The legs 11 are substantially tubular in cross section and each leg is provided with a rubber foot 16 to prevent'marring the floor and to prevent the chair from sliding or creeping.

The'foot 16 is preferably made of soft rub ber, although it may be made from other soft yieldable material, if desired. The foot has a knob 17 and a body portion 18 which tapers slightly toward its inner end. The knob is larger in diameter than the body portion to" provide an annular shoulder 19 which will bear against the outer end of each leg. A hole 20 is providedin the foot and extends through its entire length. This hole is enlarged in the knob at 21, as clearly shown in the drawings and particularly in Fig. 6

thereof.

A washer 22 is embedded in theknob where the enlargement 21 begins, and provides a bearing for a bolt 23. The bolt passes through the hole in the foot with its head 24 hearing against the washer 22. A washer 25 fits over the threaded end 26 of the bolt to form a bearing for the nut 27.

The washer 25 is substantially as large in diameter as the inner end of the body portion, and it has a' plurality of lugs 28 struck up therefrom which engage the nut 27 and prevent the nut from turning when the bolt 23 is being tightened.

In practice the bolt 23 is arranged in the -hole19 with the bolt head 24: bearing against the washer 22 and the threaded bolt end 26 extended through the inner end of the body 1 portion. The washer 25 is then arranged on the end of the bolt and the nut screwed on,

until it seats within the lugs 28. The parts tubular leg 11 until the outer end ofthele bears against the annular shoulder 19. screw driver or other implement is then arran ed in the slot 29 in the bolt head 24 and the olt tightened. The lugs 28 prevent the nut from turning so when the bolt is turned the rubber between the washers 22 and 25 will be compressed and swell out against the inside of the leg and firmly secure the foot in position on the leg.

The invention provides a foot for chair legs and the like which is securely maintained in position and which can be readily and quickly assembled. The knob has its outer periphery flush with the outside of the leg and presents a finished and neat appearance. The foot is simple in construction, efiicient in use, and can be readily and ,economically manufactured.

Changes may be made in the form, construction, and arrangement of the parts without departin from the spirit of the invention or sacri cing any of its advantages, and the right is hereby reserved to make all such changes as fairly fall within the scope of the following claim.

The invention is hereby claimed as follows:

A furniture foot consisting of the leg of a chair or the like, having a cylindrical bore, a resilient cushion member having a cylindrical shank'fittin into said bore, the head at the outer end 0 the shank being ofgreater diameter than the shank proper, whereby it may abut the end of the chair leg, a washer abutting the inner end surface only of the shank of the resilient member and covering substantially the entire inner end surface, a screw extending axially through the resilient member, and a nut for the inner end of the screw, the washer having projections to prevent the nut from rotating when the screw is rotated, and the washer making inner end surface contact only with the shank portion of the resilient member,'whereby when the screw is tightened, the shank portion is compressed longitudinally, whereby the shank expands within the leg substantially uniformly throughout its length, the outer end of the resilient member bemg countersunk to accommodate the head at the outer end of the screw.

In witness whereof, I have hereunto sub scribed my name.
