The arms and the pivted supporting members 34 are adapted to swing downward and -lie -below 'the plane ofthe .upper faces of Athe seat and the back,

when the latter is arranged' in a slightly in{ clinedor a horizontal position to form a cot A or couch,'as illustrated in Fig. 5-of the draw in' :I 'F 1 *The ront section 'or leg rest 5 is provided with an approximately rectangular frame' 37, composed of sides and a connecting' front portion38. The. sides are also connected byv front and rear cross bars 39 and `40, to-whichlon'gitudinal slats-41 are secured. The slats 41 are arranged in parallelism and-inralinement with the slats 6 and 427 of thewseat and theback. 4The front cross barBQL-is alsof'provided with anupward-ly" projecting an 42, forming .a

. stop or retaining a eus ion o r mattress in.

which terminates short of the sides of t-he. frame 9 to permit thehinged front sect-lonv or le rest to fold beneath the seat, as illustrate in Figs. 1 and 2 of the drawings. In this position the hinged section or rest 5 is o ut of the way, and at thesametime it is in -a convenient be readily arrange y No means is shown in the drawings for securing the foldable leg rest in its position beneath the seat, and any mea-ns may .be @Iployed for this purpose. The hinged front section or rest 5 is supported in an 1nclined position b valid chair, as ilustrated4 in Fig. 3 'of the drawings. The braces 44,l which extend forwardly and upwardl are connected with t e same at a oint. 1ntermediate of the ends thereof bytlliepivots 17, and vthe outer or upper portions of the brac 44 are provided with longitudinal slots 45 for vthe of the leg rest or section 5 at a pointinter-l med-iate of the front and rear ends of the same. By adjusting the braces through the slots and the clamping bolts, the'hi' ed front section or rest 5 may besupporte at different elevations.

The front section or rest 5 is also equipped with supplemental legs upper ends to the sides of the frame 37and connected at an intermediate oint by a cross bar 48, provided at its are pl'voted by suitab e osition to enable it toA for use-when desired.

The pivotal cross bar 48 is secured by a. clamping bolt 50 to the lower or inner portionof a brace 51, connected at its upper or front end -by ayhinge 52 to the front ortion 38 of the :frame 37 at the center of t le'said portion 38,11 d providedat its lower ortionwith a loliitudinal slotV 53, in which the bolt 50 operates. adapted to hold the-legs 47 i'n a vertical position when the front section 5 ,is arranged horizontally, and the said brace 5 1 is also adapted to hold the legs 47 in an inclined positionabove the supporting I surface, as illustrated in Fig. 4 of the drawings, when the parts are arranged to form a rocking chair. The rear portion of the seat is equipped with a 4central'brace 54, connected at its upperend by a hinge 55 wlth the reanoonnecting portion of the frame 9 and provided with a longitudinal slot 56 for the reception of a. y,clamping bolt 57, which adjustably .secures a pivotal cross bar 58 to' the lower portion of the l'brace 54. The cross bar 58 1s provided with terminal ears or lugs 59, which are pivoted to the inner faces of the 'at its lowerv portion rearlegs at the lower portions thereof. The legs are adapted to be rigidly Secured in their supportln position to su )port the seat in a horizonta position, an( the back is adapted to he secured in an inclined position by the rear upper braces 29. This forms an ordinary or Morris chair, as shown in Fig, l. The application of rdckers to the legs converts the chair into a rocking chair, as shown in lfig. 'hen it is ,desired to `convert the chair into an invalid chair` the front section or leg rest 5 is swung from beneath the seat and is secured in such position by the lower front` inclined brace Jet. 'ith this arraugel'uent the rockers may or may not be employed. The back is adapted to be swung downward to a horizontal position to form an extension of the seat in arranging the parts as a cot or couch. and when arranged in this position, as illustrate-d in Fig. 5 of the drawings, the inner ends o'f the slats 2T overlap the adjacent ends of the slats t3 and rest upon the same. This rovides a rigid support for the slats 27, W lich are not connected at their lower ends'with the sidepieces of the back in order, to form the. said yleldable lower portion for the same. The downward swinging of the 4back 4 carries the arms 32 downward below the plane. of the upper face of the seat so that they will be out 'of the way. The front section is then arranged in a horizont-al position to form the frontportion of the cot: or-

couch, Vhen it is desired to fold the chair for packing or storing, the back is swung downward to a horizontal or approximately horizontal position; the lfront section ,is folded beneath the seat and the front and rear legs 2 and 3 are folded at the sides of the seat. rPhe su plmental legs fold withinl the frame 37 of t e section 35, the spaces 60 between the ends of the guard and the sides of the frame t) permitting its operation and receiving the'tern'iinals of the sides of the frame 37. When' the parts are thus arranged the chair occupies but 'a small amount of space.
