ADJUSTABLE RECLINING-CHAIR.

SPECIFICATION forming part of Letters Patent No. 336,115, dated February 16l 1886.

Application filed March 30, 1885.

T all whom it may concern:

Y Be it known that I, ARTHUR OGDEN HUB- BARD, a citizen of the United States, and a resident of Sauk Centre, county of Stearns, and State of Minnesota, have invented certain new and useful Improvements in Adjustable Reclining-Chairs, of which the following specication is a full, clear, and exact description, reference being also had to the accompanying drawings, in which- Figure l is a side elevation, Fig. 2 is a front elevation, and Fig. 3 is a rear elevation, of one of the chairs complete. Fig. 4 is a detached perspective View of the foot-rest. Fig. 5 is a detail in section of aportion of the armrest, 85e. Figs. 6 and 7 are enlarged detached details of the brake mechanism. Figs. 8,v 9, and are details illustrating the construction of the seat portion of the chair. Figs. 1l and l2 are enlarged perspective views of the seatbrace clamping-joint.

A A'l are two bars forming the sides of the back-section, B B'l two similar bars forming the sides of the seat-section, and C C2 two similar bars forming the sides of the foot-section, the lower ends of the backbars A A2 being united by hinges a to the rear endsof the seat-bars B B2, while the upper ends of the foot-bars C C2 are united by hinges c2 to the forward ends of the seat-bars B B2. The hinges a are detachable, so that the back-bars may be disconnected from the seat-bars when A the chair is to be folded up, as hereinafter explained.

Any suitable form of hinge may be used; but in practice I have found that simple screweyes answer the purpose admirably. The back-bars A A2 and the foot-bars C C2 are perforated, as shown, to receive lacing-cords b, by which the canvas or other textile body or web D may be secured to the bars, as shown. The outer edges of the bars A A2 and C C2 are grooved, as shown at d in Fig. l, the grooves connecting the outer ends of perforations, so that the 1acingcords b will be elnbedded in the bars, and not only out of sight, except from the sides, but protected from wear by the over-projecting wood of the bars. The lacing is held in the grooves, as it reaches from one perforation to another, by being drawn taut in the perforations. At its ends the web D will be turned over and sewed Serial No. 160, 598.

down, leaving heins, in which the end bars, A3 and C, will be inserted. These end bars are held in the ends of the bars A A2 and C C2 by tenons on their ends fitting into mortises in the ends ot' the bars, as shown. The lacings b, by being drawn tight, will thus hold the side bars in place with reference to the web, while the hems on the web will hold the end bars in place iu the bars. The lacings also permit the web to be easily and quickly tightened in event of its becoming loosened, or the replacing of a worn or torn web., The webs may be of any suitable materialcanvas, carpet, or other materialor a con1- bin-ation of two or more materials. The Seatsection is re-enforced underneath by an extra web, E, (see Fig. S, 9, and 10,) which is formed of a tube of canvas having circular bars F F2 in its interior, by which it may be secured to the inner edges of the seat-bars B B2 by screws or nails c. The web D lies over this auxiliary web E loosely, and completely hides it, the function of the latter being to give additional support to the web D, where the greatest strains occur. On the inner lower edges, at the centers of the bars B B2, metal sockets G G2 are secured, each supporting one end of a brace, H H2, each of the latter being provided on its other end with a clampingplate, K K2, the adjacent surfaces of the latter being provided with radiating intcrloclc ing notches 7i, (see Figs. ll and 12,) and adapted to be clamped together by a bolt, fi. It will be readily understood, therefore, that' by loosening the bolt t' until the plates K K2 are disconnected, the bars H HAZ may be pushed upward by their lower ends, and spread the bars B B2 apart, and hold them thus by again tightening up the bolt t'. By this means the bars B B2 are not only held apart and prevented from being drawn toward each other by the pressure upon the webs D and E, but the latter may be retightened in event of sagging.

M M2 are the armrests, which are connected at their rear ends by brackets to the back-bars A A2, near their lower ends, while the forward ends of the armrests are connected by similar brackets to the foot-bars C C2, as.,

shown. These brackets consistof small metal bars N', pivoted by their ends in the ends ot' the arm-rests, and also in slots cut into the ICO ets N N2 are each of them rigid, so far as their connections with the back and foot sections are concerned, and have the armrests pivoted loosely in their outer ends. Attached to the under side ot' each arm-rest is a chock7 or ro stop, P', whose functions are to check and regulate the throw of the chair, as hereinafter shown.

The three sections above described,vand covered with the web D, are arranged to be mount- 1 5 ed upon and supported by a folding base or frame, as shown. This frame consists of two legs, R' R2, pivoted at n to the seat-bars B B2, near their forward ends, and having two other shorter legs, R3 R2 pivoted at r to the legs R 2o R2, the legs R R2 being also connected together by a round, R2, and the legs R3 R4 being similarly connected by around, R, while a chain or chains, R2, are arranged to connect the rounds, to prevent the legs spreading too far apart,

while at the same time adapted to allow the frame to be folded up, as hereinafter shown.

R8 R9 are two arms rigidly fixed by opposite bracing-bars, t t2, which connect their lower ends to the legs R R2, while their upper 5') ends are pivoted at n to the back-bars A A2,

near their lower ends, Aas shown. By this means the jointed back, seat, and foot sections are poised upon the. frame,and may be bent upward into a chair shape with the back and foot sections at right angles to the seat-section; or the back-section may be turned down to nearly a horizontal position, which, by reason of its having the arm-rests pivoted thereto, will cause the foot-section to be thrown 4o upward to a correspondingly-horizontal position, and thus transform the chair into a couch. Ot' course the chair may be placed in any intermediate position which may be desired. The A"chocks or "stops7 P are so arranged that, when the chair is bent up into the form of an ordinary chair, the lower ends of the chocks will strike the seat-section and arrest the further forward movement, and preventthe back-section folding over upon the other 5o parts or upon the occupant of the chair. The

checks also perform the same office when the .chair is transformed into acouch, by striking the seat-section at the other endof the stroke and preventing the back section from sinking too low. Beneath each of the chocksPcurved guides P2 are attached to the seatsections,and provided with channels in theirupper faces, in which the lower ends of the checks run, to prevent the clothing of the occupants of the 6o chair from catching beneath the checks.

T is a rod passing through the arms R8 R2, and provided on one end with a head, c', and on the other with a cam hand-wheel, T2.

T3 is a bar pivoted by one end at o2 to the '65 side bar, B, and having a slot, v4, in its other end, through which therod T passes.

T4 is a small cam-disk,having lugson its rear face by which it fits over the vbar T2, and is prevented from turning thereon, and having clutch-teeth c5 on its outer face corresponding to similar teeth, c", on the cam hand-wheel T2. The rod T passes through the slot in the bar T2, and also through the cam-disk T2, and is rigidly fixed in the hand-wheel T2. By this simple device a brake is formed by which the bar T3 may be clamped to the arms R8 R9. and thus hold the chair at whatever inclination the occupant may desire. The length of the rod T will be graduated to correspond with the distance between the arms RB R9, so that when the straight sides of the teeth v2 o6 are in contact the bar T3 will be loose and free to be moved by the adjustment of the chair; but when it is desired to lock the chair in any desired position,tl1en it is only necessary for the occupant to turn the hand-wheel T2, which will cause the clutch-teeth to move the handwheel away from the cam-disk and compress the bar T3 firmly between the arm R8 and the cam-disk. A foot-rest is arranged upon the chair, consisting of a main bar or foot-rest, fw',

and two small side bars, 102 w, the latter pro.- vided with small pegs ww5,which are adapted to rest above and below the foot-bars C C2 when' the rest is inserted into its place, as shown in Figs. l and 2. The pegs w* thus hold the rear end ofthe footrest and preventits being pushed out by the foot of the operator. Additional pegs, will be inserted into the lower sides of the bars C C2, above which the pegs w* may be placed when it is desired to adjust the rest to suit younger or shorter occupants of the chair.

The connections between the supportingframe and the chair or seat port-ion will he so arranged that they may be disconnected to enable tlie chair to befolded up for transportation. Nearly all' the other parts are also adapted to be disconnected, so that the-chair may be folded up into a small space for convenience of transportation.

Having described my invention and set forth its merits, what I claim isl. The seat-section, back-section, and footsection hinged together and having the web D, attached thereto by lacings b, and provided with brackets N N2 and arm-rests M M2, connecting said brackets, in combination with a folding supporting-frame consisting of legs R R2, pivoted to said seat-section, bracing-legs Ra R4, exible connections R2, and arms R8 R, attached by one end to said legs R R2, and pivoted to said back-section by their other ends, substantially as and for the purpose set forth.
