u ffarney Patented May 21, 1940 UNITED STATES PATENT OFFICE ARM REST Application August 1, 1938, Serial No. 222,430

10 Claims.

My invention has to do with armrests. More particularly, it relates to arm rests which may be easily mounted on. and detached from chair arms and the'like.

In the manufacture of metal furniture such as chairs, swings and settees, it has been the practies to weld, screw or rivet the arm rest onto the arm, out this practice is undesirable not only from the standpoint of cost, but also since the screw or rivet heads present objectionable protuber ances on the arm rest surface.

It therefore among the objects of my invention to provide an arm rest which may be quickly and easily applied to the arm without screws, rivets or welding, and which may be easily detached therefrom if desired.

It another object to provide an arm rest to which a fabric or like covering may be easily applied and eifectively retained in place.

Another object is to provide an arm rest which is simple in structure, economical of manufacture and installation, durable and highly efilcient in use. 9

Other objects of my invention will appear hereinafter My invention consists in the combination and arrangements of parts andmethodoi application hereinafter set forth and claimed, and will be best, understood from the presently preferred adaptation thereof which I shall now describe, for which purpose Ishall make reference to the ac:- companying drawing, in which:

Fig. l is a side elevation showing my device applied to a chair arm; X

Fig. 2 isa plan View .on line 22 of 'Fig. 1;

Fig. 3 is an end view on line 33 of Fig. 1;

Fig. 4 is a cross-section on line 44 of Fig. 1;

Fig. 5 is an enlarged fragmentary bottom view; and

Figs. 6 and 7 are cross-sectional views, similar to Fig. l, but showing variational forms.

The numeral 5 (Fig. 1) denotes a metal chair having corner posts 6 and arms 1 made of channel iron, and a seat member 8.

My improved arm rest In comprises a casing l i which preferably is in the form of an elongated loop, although it will be understood of course that the casing may be of any desired suitable shape. Casing H has an inwardly depending peripheral flange l2 at its top and bottom. inwardly depnding peripheral, oppositely disposed flanges l5, l5a. At each end of the casing II the lower portion of the casing is cut away to provide a recess i6 for mounting the arm rest over the chair arm, the chair arm resting in the recesses It provided by the cut-away portions in the casing. The top portion of easing H has an opening l1 into which fits (from the underside of the casing) a closure plate It, the downwardly and outwardly depending apron 20 of plate [8 fitting under casing flange 2 to prevent upwardescape of the plate. The top face of plate It may be covered with a suitable fabric 22 as will later be described.

A .lleshaped cross-bar 25 is inserted in the casing l i and bears at its bottom against the top face of chair arm "I and at its top against apron 26 of plate E3, the bottom portion of the cross-bar being upwardly bowed at its center, as shown at .26, .so as to conform somewhat to the rounded surface of the chair arm, The device is held firmly in place on the chair arm by means of a U-shaped spring clip 3% positioned under the cross bar and whose side walls each terminate in an outwardly and downwardly depending fiange 3| the clip extending ,under the chair arm ,1 and the clip flanges 3i resting against the top surface of the respective casing flanges I5, l5a, thus tending to draw the armrest assembly against the top face of the chair arm. .While any desirable number of cross-bars 25 and spring clips 3!] 2 members .25 in place atop the chair arm and then force the spring clip 73% upwardly around the .chair arm and into the casing until the ,clip

flanges 3| spring out over the respectivecaslng flanges l5, l-Ea, after which the device is firmlyre- .tained in position on the chair arm. To remove thearm rest, the sides of the clip 30 are ,com- 4 pressed until their flanges3l escape from over casing ,flange 15, l5a.

The device of Fig; 6 is identical with that be- .before described except that the arm rest isthere shown as applied to an arm 40 which is rectangular in cross-section.

In Fig. 7 the device is shown applied to a round tubular chair arm. 50 and here the device is the same as'before described excepting only that the bottom portion of the clip 30a is curved to conform to the round chair arm, and in order toprevent turning of the arm-rest on thechair arm, the chair arm 50 is provided with a hole 5! and the bottom of clip 30a is depressed at 3072 to provide a lug which projects into the hole 5! to provide a detent against rotation of the clip with respect to the chair arm. The lug b is preferably at the center of the bottom portion of the clip 30a.

While I have illustrated and described the preferred form of construction, I do not wish to limit myself to the precise details of structure shown and described, but .desire to avail myself of such variations and modifications as may come within the scope of the appended claims.

I claim: I

In combination with thearm of a chair or the like, an arm rest comprising a casing resting against the top of the arm and having inwardly extending, oppositely disposed flanges at its bottom and a spring clip engaging the bottom surface of the arm, said clip having terminal portions engaging said respective flanges to clamp the arm rest against the arm.

2. In combination with the arm of a chair or the like, an arm rest member on the arm, means for clamping the arm rest member onto'the arm including a clamp having its top medial portion engaging the underside of the arm and its end portions engaging the arm rest member, and means for resisting movement of the clampwith respect to the arm, comprising a recess in the arm and a lug on the clamp, said lug projecting into said recess.

3. In combination with the arm of a chair or the like, an arm rest comprising a casing resting against the top of thearm and having inwardly extending flanges at'its bottom, and a U-shaped spring clip engaging the arm, said clip having terminal portions engaging said respective flanges to detachably hold the arm rest against the arm.

4. In combination with the arm of a chair or the like, an arm rest comprising a casing resting against the top of the arm and having inwardly extending peripheral flanges at its bottom and a U-shaped spring clip engaging the arm, said clip having terminal portions engaging said respective flanges to detachably hold the arm rest against the arm, and said arm rest casing having a removable cover plate. l
