8 Claims.

.This invention relates to a foot applied tothe legs-of chairs.

The primary'object of the invention is to providea new and improved resilient foot for chairs,

which foot is provided with reinforcing means against which the metallic ends of the chair legs engage.

Another object of the invention is to provide a chair foot which is provided with a resilient w or rubber foot portion for engaging the floor, which is provided with a metal .portion engaging the rubber foot portion and upon which the metal ends ofthe chair legs rest, and which is provided with an upstanding fin which engages a slot or opening in the chair leg.

A further object is to provide an improved chair foot which has a metal leg supporting portion into which a flexible rubber fioor engaging portion is held, and which is provided with a longitudinal slot therein through which an inturned leg of an upstanding fin is received, the

fin being adapted to extend upwardly along a face of the chair leg at the lower end and having a hole provided therein into which the metal :of the chair leg is upset for'securely holding the footmember in position on the end of a metal chair leg.

Astill further object is toprovide a novel metal chair foot which has a resilient floor engaging portion capable of being quickly and economically applied to the lower ends of the chair ends, and

which can be readily and economically manufactured.

Numerous other objects and advantages will be apparent throughout the progress of the following specification.

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

Fig. l is a *detail elevation of a chair leg and embodying the invention.

Fig. 2 is adetail sectional view of the device shown in Fig. 1.

Fig. 3 is a'detail sectional View on the line 3-3 of Fig. 1.

parallel tubular reinforcing members 9 and 10 reinforcing material 23 is imbedded in the porand an intermediate inside connecting member 11 which is spaced from the outside connecting member 12 to provide a longitudinal recess 13 which is preferably in the form of an elongated rectangle.

The chair foot, which is designated generally by the numeral 14, is provided with an inverse elongated metal tube-shaped member 15 which is adapted to be engaged by the underside .of the metal legs 6 as indicated at. 16. The member 15 is in the shape of an-ovate oblong having parallel sides 1'? and rounded or circular ends 18. The member 15 in cross section, has its free ends 19, Fig. 3, extending inwardly to receive the upper portion 20 of a resilient foot portion or block 21. This resilient foot portion may be of any kind of soft yieldable material desired but in the present instance it has been found preferable to make it of rubber. The upper portion 20 may be made of any kind of material desirable but it has been found preferable to make the portion 20 of the same material as the portion 21. In orderto. prevent breakage between the upper portion 20 and the lower portion 21 at the line 22,

tion 21 and extends up into the portion 20. This reinforcing'member may be of any material desirablebut in actual practice it has been found that a fabric, such as canvas, sufficiently reinforces the rubber foot.

The member 15 is provided with a longitudinal slot 24 through which an upstanding fin 25 extends. The lower end of the fin is bent at right angles, as indicated at 26, to provide an inwardly extending arm or leg 2'7. The upper side of this arm or leg may engage the lower side of the member 15, as indicated at 28, while the lower side of the arm or leg may engage the top of the reinforcing member as designated at 29, Fig. 3.

The fin 25 is adapted to extend up into the recess or opening 13 between the sides 11 and 12. The fin 25 is provided with a hole or opening 30 into which the metal of the inner side of the leg 11 is upset, as indicated at 31, for the purpose of locking the fin25 and consequently the entire foot in position to the leg of a chair. The opening 13 diminishes in size as itextends upwardly until the sides 11 and 12 contact, as indicated at 32, Fig. 3. If desirable, the fin 25 may be provided with

upstanding legs

33 and 34 which legs extend upwardly along the chair leg at a point beyond that indicated at 32 in Fig. 3 to give extra bracing for the leg, and the intermediate notch 35 between the legs may extend downwardly toward the perforation 30 to reduce the distance over which the impressed portion 31 has to travel during the insertion of the fin 25 into the leg 6.

While the invention has been designed primarily for use on chair legs it is, of course, derstoc-d that the present foot herein shown and claimed is applicable for other structures, such as tables and the like. The present invention provides a soft resilient furniture foot particularly for use on metal chair legs to prevent marring of the floor upon which the chair rests. The metal member 15 provides a solid backing for the bottom of the metal chair and prevents the end of the chair from cutting into the flexible foot portion. The metal member 15 also provides novel means for holding the rubber foot in proper position as well as providin a support for the upwardly extending fin. "he entire device may be readily and economically manufactured and quickly applied in place. The upsetting of the metal of the chair leg through the hole in the fin locks and maintains the foot in proper position at all times.

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

The invention is hereby claimed as follows:

1. The combination with a furniture leg having an opening therein, a metal member engaging the bottom of said leg, said memb r having a slot therein, a fin extending through aid slot, a leg bent from said fin and engaging the underside of said member, fn having an opening provided therein, an upset portion on the furniture leg extending into said opening for locking the fin to the furniture leg, a block carried by said member, and reinforcement in said block and extending upwardly in the block substantially to the leg on the chair.

2,-The combination of a metal chair leg having a narrow elongated opening therein, a metal member engageable with the bottom of the chair leg and upon which the chair leg is supported, a resilient foot having an upper and a lower portion, the upper portion of said foot being grippingly received by said metal member, strengthening means imbedded in said upper and lower portions, said metal member having a slot therein, a fin passing through said slot and engaging the opening in the chair leg, said fin having a part arranged inside of the metal member and engaging a part of the resilient m mber, said fin having a hole therein, a part or" the metal of the chair leg being upset and extending into the opening in the fin for locking the fin to the chair leg.

3. The combination of a metal chair leg having a narrow elongated opening therein, a metal member engageable with the bottom of the chair leg and upon which the chair leg is supported, a resilient foot having an upper and a lower portion, the upper portion of said foot being grippingly received by said metal member, strengthening means imbedded in said upper and lower portions, said metal member having a slottherein, a fin passing through said slot and engaging the opening in the chair leg, said fin having a part arranged inside of the metal member and engaging a part of the resilient member, s id fin having a hole therein, a part of the metal of the chair leg being upset and extending into the opening in the fin for looking the fin to the chair leg, and arms on said fin engaging a side of the chair leg.
