Be it known that I, H. B. BRAMAN, of Boston, in the county of Suffolk, and State of Massachusetts, have invented a new and useful Improvement in Reclining-Chairs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 represents aperspcctive view of a chair embodying my improvement.

Figures 2 and 3 are detailed views off-portions of the chair, showing the method of connecting the joints.`

The object of myviuvention is to provide a means for securing the chair in any required inclined position, and at thclsame time, when so secured, to admit of its yielding to a sudden forcible movement imparted by the occupant, without breaking or injuringr the joints or fastcnings; and the invention consists in the employment of a slotted'movable bar, pivoted to the support, connected with the foot-rest, in connection with a pin provided with a head or thumb-piece on the outside, and passing through the slot and the side of the main stand. On its inner end is secured a washer, made oi' some elastic or yielding material, which, being forcibly pressed against the slotted bar, serves to hold-it in positionunder the ordinary pressure of the occupant; but in the event cfa sudden or foreiblemovcment of the body of the occupant to rise,tl1e plate or bar will gradually yield to the pressure, and allow the chair to conform to the movement withoutbreaking or injuring thc joints ofthe chair. The parts of the chair are so arranged as to conform readily to the body, whether a reclining or sitting position. v

In :i'eclining-cl'iairs devices, are sometimes employed for retaining the parts in such position as may be desired by the occupant. Such devices are usually made to secure the chair in a ixedposition, and in case the occupantsuddcnly rises from the chair, a great strain is brought to bear upon thc joints, causing the latter to frequently break, and thus injure or interfere with the efficiency of the chair. The ordinary method of securing the chair in position is by means of a rack or toothed bar engaging with a pin, thus securing the chair in a iixel position.

Referring to theV drawings, A A represent the main frame or stand, which may be made of wood or metal, and to which the movable parts are pivotcd. B C D represent the diH'ere-nt portions of the movable frame, as at a a. The movable frame is composed qf the back, C, the seat-frame B, and the leg or foot-:rest D, so connccted together as to be readily accommodated to the position of the body, whether in an inclined or sitting position. The back frame C and f oot or leg-rest D turn upon the stationary pivots or pins a a 'on the main or stationary frame A, and they'are connected together by means ofthe arm-pieces or rests c c andthe seat-frame B. The portions ofthe movablefframe are connected together by means of a peculiarly-formed joint, as 'shown in iig. 3, and designated `by 6 in iig. 1. It consists ot" a plate of metal, of the shape shown in said ligure, having a pin or projection, CZ, as seen in iig. 3, on one side, and provided with a hole for the insertion of a screw, by which it is attached to the seat-frame B, by which means the plate and pin are securely held in place, so that the portion D and C can turn freely on the same without the liability of loosening the pin or connection. In reclining-chairs, as ordinarily constructed, the moving portions are confnected together by means of screws, which are liable to become ,loosened by frequent use, and render the chair ineiiicient. i

By my method of thus connecting the movable to the stationary frame, I am enabled to attach the parts together after the upholstering is completed, and in case of transportation the parts can be readily taken apart and packed in a small compass. To the front portion of the movable frame is attached a bar, E, extcnding backwards, and formed with a slot at its rear ent, The slotted portion of the bar E fits upon 4a rod, F, which passes through the side of the main frame or stand A, and is provided with a knob, G, on the'. outside. On the inner end of the rod is secured ahead, with a washer of India rubber or some other elastic substance, so that when the knob is screwed upon the rod the washer will be tightened against thc bar E, and thus hold the movable portion of the chair suficicntly iirm to retain it in any convenient position for the bodyA of the occupant. Should a sudden movement be made by the occupa-nt, such as to bring a severe strain upon the bau E and rod F, the bar will gradually yield sufficiently to prevent any breaking of the parts, as is common in chairs of this description, which have thc rigid fastenings, when they are subjected to such sudden strain.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination of the slotted adjusting-bar E with the rod li and elastic washer, substantially as and forthe purpose specified. l l

2. I claim, in combination with the above, the device b cl, constructed as described, for connecting together the portions of thermovable fra'uic, as and for the purpose set forth.

Intestimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.

H. B. BRAMAN.
