I0 of the base 8. It is to be observed that the Inrthe drawings-f c f front and rear edges I9, 20, Figs. 3 and 4, of the Fig. 1, Sheet 1, Ais'a front elevation of aconseat body member I6 are opposingly beveled for plush or plastic, and of pleated, tufted or smooth character. Furthermore the cushion covering may be made of material and appearance corresponding with the upholstery of the furniture with which the foot and leg rest of my invention is to be associated or used.

Turning now to the means' for pivotally attaching the limb rest 9 to the base bearingsections I3, said sections are tted with substanl" tially similar special angle- brackets 24, 25 respectively, Figs. and 7, the major or vertical flange portions whereof are inset in complementally shaped recesses 21, formed in the side members I8, and said brackets are secured in place as by attaching screws 28, Fig. 5, engaged through holes 29 in the flange portions 2 6, see Figs. 5 and '7 to best advantage; Whereas the minor or horizontal ange portions 30 of the brackets 24, 25 seat on the confronting end sections of the spring-supporting member I4 and are rigidly attached thereto byv carriage bolts 3| engaged through the ends of said member I4 and holes 32 in the flange portions 38, see Fig. 2, to best advantage. formed with undulated side anges 33 whereby said. brackets are materially strengthened, while it is to be particularly remarked that said flanges 33 dene motion limiting stops controlling the The respective brackets 24, 25 arev angular pivotal movement of the limb-rest 9, as,

base side member I0, see Figs. 1 and 2, for a purpose later on hereinafter explained; while 36 indicates the bearing portions for the pivot elements or studs 31 supporting the limb-rest 9.

Secured to each of the dependent rockers I8 of the limb rest 9, for coaction with the confronting face of the respective angle- brackets 24, 25 is a plate element 38 embodying an orbicular lower` portion or conveniently of the shape best shown in Fig. 6, and inset in a complementally configured recess 39 provided for its reception in the associated rocker IB. Each plate element 38 embodies a tubular bearing portion 4'0, a round section dowel projection 4I on the inner face of said element 38, and an arcuate pad 42 on the outer face thereof. It is to be noted the lower portion of the plate element 38 registers with that of the associated rocker end portion, and that the bearing portion engages in an orifice 43 bored through the rocker I8; whereas the dowel projection 4I seats in a boring 44 whereby said plate element 38 is positively restrained from lateral movement relative to the associated rocker I8, and that it is conveniently secured in position by appropriate screws 45.

Referring again to the pivot studs 31, it will be observed that each such stud embodies a relatively reduced extension 46, for snug engagement in the bore of the bearing portion 36 of the associated angle bracket 24 or 25, and that it is peened over or riveted at 41 to effect its rigid atlthe same is by way of illustration only.

tachment thereto in an obvious manner. Cotter pins 4'3 are passed through suitable diametric holes at the outer ends of the pivot studs 31 to prevent any lateral shifting of the limb-rest 9 with respect to the base 8, as well as to positively maintain the coactive parts of the respective brackets 24, 25 in contact with the confronting portions of the plate elements 38.

In order that the limb rest 9 may normally return to the horizontal with respect to the base k8, when limb weight is removed therefrom. while positively retaining its intended capacity for oscillatory movement on the pvot studs 3i, I provide the member I4, and the underside of the limb-rest body member I5, with spaced and axially aligned pads or seating elements 49, 5i), respectively for reception of the outer ends of double helico-volute compression springs 5i having capacity for oscillation relative to their respective longitudinal axes.

` To `maintain or lock the limb rest E! horizontal or at a definite inclination I provide the arcuate lpad 42 of one or both of said limb rest dependent 'knob 56 whereby it is manipulated in an obvious manner.VV Thus it will be readily understood that by retraction of the plunger latch and rocking the limb-rest 9 to the right or left-hand, said rest can be s'et at a deiinite inclination dependent only upon which of the outer apertures 52 has the plunger latch 54 pushed thereinto; also that, when the said plunger latch is moved into the central aperture 52, it will be self evident the limb-rest 9 is locked horizontal, whereupon the device may be used as a hassock or stool. A suitable fabric protective or cover-in element 5 is passed below the spring supporting member I and attached to the underside of the limb rest body member I5 as by clamp strips 5S and securingmeans 59. Incidentally the cover-in element 51 is free to ride under the spring-supporting member I4, and it may `be of any desirable material and have the side edges undulated as indicated at 88 in Fig. l for esthetic reasons; while it is to be particularly remarked said coverin elements 51 serves to protect the springs from becoming unduly flexed outwardly in either a forward or rearward direction.

From the foregoing it is felt that the merits and advantages inhering to my improved limb rest will be clearly apparent; and while I have shown and described a preferred construction,

in. thermore I consider as my own all such modifications in construction as fairly come within the f scope of the following claims.
