IMPROVEMENT IN ADJUSTABLE RECLINING-CHAl-RS.

Specification forming part of Letters Patent No. 145,595, datcd December 16, 1873; application tiled July l0, 1873.

To all whom it may concern:

Be it known that l, GEORGE A. ScHAsTEY, of New York city, in the State of New York, have invented certain Improvements relating to Household Furniture, of which the following is a specification:

l will describe the invention as applied to an arm-chair, but certain portions may be also applied to lounges, in which the'upright or nearly upright heads are changeable or adjustable in position.

The following is 'a description of what I consider the best means of carrying out the in-. vention.

The accompanying drawings form a part of this specification, and represent an arm-chair with the back and arms in two positions.

The chair is easily changed from one con dition to another without inclinin g the arms, and it may, if desired, be allowed to change the position of the parts according to the strains impressed by the occupant, or it may be instantly locked in any desired position.

Figure lis a side elevation, partly in section, with the back in an upright or nearly upright position. In this condition the arms are in their extreme forward position. Fig. 2 represents the same chair, with the back considerably inclined or drawn backward, and with the arms correspondingly changed in position but not in inclination. Both figures rep- 'resent the parts as locked.

Similar letters of reference indicate like parts in all the figures.

A is the seat o r main body, provided with rigid legs, which may be of any ordinary or suitable pattern. I have represented the front legs as more ornamental than the rear legs. Rigid uprights A1 A2 extend up from the seat or body in the proper position to support the arms, which latter arel peculiarly constructed and connected. B represents one of the arms in vertical section. It is a partially-hollowed piece, adapted to slide backward and forward on the two separate uprights A1 A2, which match in a longitudinal groove extending along the base of the arm B. The rear upright A2 extends up farther than the front upright A1, and forms the rear abutments for a coiled spring, C. This spring acts at its front end against the interior of the sliding arm B, and tends to urge it forward. D is a link, pivoted flexibly within the rear end of the sliding arm B, and also flexibly to the back E, which latter turns on a pivot, e. The spring C, by urging the arm B forward, holds the back E upright.

When the occupant of the chair reclines backward forcibly against the upright back E it pulls on the links D, of which there are two, one on each side of the chair, connected to corresponding sliding arms, and slides the arms B backward against the tension of the springs C. If it is desired to prevent such motion, or to hold it in the back position when such has been attained, and prevent its being returned the moment the occupant leans forward or rises from the chair, the catch-bolt M is allowed to rise by the action of its spring m, and engage in one of the series of holes nl n2, &c., represented. The catch-bolt M may be held down against the force of its spring m, when desired, by providing abroad ilat place on its lower end, traversing through a corresponding hole, so that when it is drawn down land quarter-turned it is held down and becomes inoperative.

G is a foot-rest, which may have any desired form. It is hinged to the front of the seat or body A, and is acted on by a rod, H, which is so mounted that it may move endwise in the frame of the chair. There are two of these rods H, one on each side of the chair, and each is surrounded by a spring, h, which abuts against a collar, H', to urge it always backward. The rear end of each rod H presses against a portion of the back E below its hinge or fulcrum c. The tension of the spring h is therefore added to that of the spring Otending to hold the part E in its upright position. When the back E is forced into the inclined position it contracts four springs--that is to say, the two upper springs C and the two lower springs h.

rIhe invention may apply with some success to that class of lounges in which two short arms are employed. On making the headA pieces of such lounges adjustable, and connect ing them to sliding arms with springs therein, the parts will serve in a manner very closely analogous to that which I have described in the operation of the above chair.

It will be understood that the parts may be upholstered and uished with any amount of elaboration.

I claim as my inventionl. The combination of the movable arms B, supporting-posts A1 A2, springs G, links D, and hinged beek E e, as and for the purposes specified.

2. rlhe sliding rod H and spring h, in conibination with the'hinged back E e and foot G,

and arranged to serve therewith, as Yherein speeied.

In testimony whereof I have hereunto set my hand this 3d day July, 1873, in the presence of two subscribing Witnesses.
