This invention relates to foot rests of the type employed upon chairs such as are used by telephoneoperators or the like. Important objects of the invention are, to provide an improved foot rest of this type and to provide improved for mounting the foot rest upon a chair.
In the drawings, 1 is a side view of a chair equipped with my improved foot rest;

Fig. 9 a section taken on the line 9-9 of Fig. 8; and r Fig. a section taken on the line 10-10 of Fig. 8.
My improved foot rest is shown as applied to a chair 1 having four tubular metal legs 2 which curve outwardly and then downwardly to feet 3 attached thereto. Just above the feet, the legs are reinforced by arcuate tubular braces 4. At substantially the point where the legs begin to curve downwardly the foot rest is mounted. It comprises a circular ring 5 formed of hard rubber molded into shape. Other suitable material may beemployed, however. In cross section the ring is, for most of its length, of the form shown in Fig. 5, having fiat upper and lower faces, straight sides and rounded corners. At four points equally spaced around its circumference the ring is formed at its under face with trans verse enlargements each forming an oblique uner face 6 and a curved concave seat 7 in said face to receive and substantially fit a leg of the chair at the point above mentioned.
The material of the ring 5 is molded around a slender reinforcing ring 8 made of steel or The ring 8 is cross section of ring 5 and at points adjacent the seat 7 of the latter, it has steel anchor plates 9 secured to its under side. Ring 8 is rectangu lar in cross section and each plate 9 is rectangular in plan, or substantially so, and along one of ward and is bent upward to lie in a plane parallel to the adjacent oblique face 6 of the'outer ring. The latter is formed in each face Gwith .two screw holes 10 located at opposite sides of the seat 7 and registering with two threaded apertures 11 formed in the plate 9.
Clips 12 are provided for attaching the foot rest to the chair. Each clip comprises a metal strip bent to form a concave seat 13 to fit around the inner side of a chair leg, and provided'with outwardly extending ears 14 at opposite sides of the seat. Screw holes are formed in said ears and are adapted to register with the screw holes 10 in the opposed face 6 of the foot rest. Through said registering holes headed screws 15 are passed and screwed into the threaded apertures 11 of the anchoring and reinforcing plate 9. Thereby the foot rest is clamped firmly in place, with each leg of the chair embraced by one of the clips and by an opposed seat '7 of the ring 5, and the exposed surfaces of the ring with which the feet come in contact are left entirely smooth. The strong metal clips are securely anchored to the metal reinforcing means within the ring and combine with said means to strengthen both the chair legs and the ring at the points of attachment of the latter. The plates 9 form part of the reinforcing means for the ring in addition to serving as anchorages for the clip screws 15. They are located at substantially the center of the cross section, of the ring for strong anchorages. The hard, molded rubber of the ring 5 strongly resists abrasion. Furthermore such abrasion as does occur will not cause a discoloration of the ring at the. spots engaged by the feet. 'By reason of its moldable character the material maybe given a de- 5 sired color which will extend throughout the en- 9 tire thickness of the ring. Then, abrasion cannot remove the color and mar the appearance of the ring. The rubber ring can also be washed or scrubbed repeatedly without destroying its color or finish.
In Figs. 8 to 10 inclusive the foot rest ring and its mounting are shown as modified for attachment to a chair having a low wood base formed with outwardly flaring feet,-one of which is shown V, at 16. Each foot has a fiat upper face 17 upon which the ring 5 is mounted. The mounting for the ring at each foot includes a flat steel plate 18 of rectangular form which is formed with a square central bolt hole 19 and two countersunk screw. holes 20 near its opposite ends. A headed bolt 21 passes through the square aperture 19 and has a squared portion 22 to prevent it from turning in said aperture. The plate is disposed against the flat under face of the ring and the latter is formed with a concavity 23 providing clearance for the head of bolt 21. Two screws 24 hold the plate to the ring. They are passed upwardly through the plate apertures 20, through apertures 10 in the body of the ring and are screwed into threaded apertures 11 formed in the anchoring and reinforcing plate 9 which is disposed against the under side of the reinforcing ring 8 The heads of screws 24 are countersunk in the under face of the plate and the latter seats upon the flat face 17 of the chair foot The foot is formed with a vertical bore 25 through which the shank of bolt 21 extends. A nut 26 is screwed upon the lower end of the bolt shank and together with a washer 27 is seated within a recessv 28 at the under sideof the chair foot. The bolt and nut firmly clamp the plate 18 upon the foot and the ring 5 is securely anchored to the plate by the under side registering with said threaded apertures; clips embracing members of the chair supporting structure; and fastening screws extending through said registering apertures, screwed into said threaded apertures and holding the clips and the ring to the chair supporting structure.
2. In a chair, a foot rest ring extending around the supporting structure of the chair and comprising an annular body of hard, non-metallic moldable material, and reinforcing means rigidly embedded in said annular body and extending around through it and comprising a metal ring and metal plates spaced around said last mentioned metal ring and extending laterally therefrom, each of said plates having a pair of threaded apertures spaced apart circumferentially of the reinforcing ring, the non-metallic material of the annular body being molded entirely around the reinforcing ring and said plates and having apertures opening through the under side of the annular body and registering with said threaded apertures in the plates; and securing devices for the foot rest spaced around the chair-supporting structure and detachably fastened thereto and each having a pair of screws extending through said registering apertures and screwed into the apertures in said plates to detachably hold the foot rest in place,the threaded ends of said screws terminating within the foot rest, and said molded material covering both the reinforcing means and said screw ends to prevent engagement of the feet therewith.
