RECLlNlNG-CHAIR.

SPECIFICATION forming part of Letters Patent No. 425,778, dated April 15, 1890.

Application fled March 21, 1889. Serial 110.304,099. (No model.)

To all whom it may concern: y v

Be it known that I, LOUIS GOETEL, of the city, county, and State of New York, have invented a new and useful Improvement in Redining-Chairs, of which the following is a further object of the invention is to provide a means whereby the movement of the vback may be regulated by the occupant of the chair without arising therefrom.

The invention consists in the novel construction` and combination of the several parts, as will be hereinafter more fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar .letters and figures of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of a chair oonstructed in accordance with my invention, in which one arm, a portion of the frame, and the forward section of the segmental guide are shown in section; and Fig. 2 is a plan view of the seat, one arm being in horizontal section and likewise the back, one arm being entirely removed, and the forward portion of the segmental guide located beneath the removed arm broken away. Fig 3 is a transverse section on line :15x of Fig. 1. Fig. 4 is a vertical section of aportion of the back-frame and that portion of the seat-frame to which the back is pivoted, illustrating the application of the spring controlling the movement of the back; and Fig. 5 is a front elevation of the bracket employed in hin ging the back to the seat.

In carrying out the invention the seat 10 of the chair is constructed in any ordinary orv approved manner, and ateach side of the seat-frame a semicircular guide 11 is secured,

one end of each guide being secured to the A seat-frame at the rear end and the other in structed of wood, and the blocks from which the guides are made are each provided with a central recess 12, extending from end to end, in the side walls of which recess ways are formed by introducing therein opposed castings 13, essentially U-shaped in crosssection, as illustrated in Fig. 3, which castings or ways are adapted to receive and support a plate 14:, curved to correspond with the radius of the guides 11, which plate is adapted to slidein the recess of the guides from one end practically to the other. One plate 14: is provid ed for each of the semicircular or segmental guides, and in the plates a series of longitudinallyarranged apertures 1 5 are produced.

i Preferably iu the construction of the guides 11 that portion from the center to the forward end is so formed that the groove 12 therein will be hidden from view, asbest shown in Figs. l and 3. If, however, it is found desirable in practice, instead of constructing the guides 1l of wood the same may be made of any suitable light metal.

The back-frame 1G of the chair is pivoted to the seat-frame in the center of the curve of the guides, and the said frame preferably consists of two strips of metal a a,bent to shape in parallel lines, the lower ends of the said strips being curved inward, as illustrated at 17v in Fig. il, whereby an outer shoulder 18 is formed, in which an aperture is produced. For a distance above the shoulder 1S the strips of metalare kept apart to accommodate one end of a spiral spring 19, which is carried through the aperture or opening in the shoulder, as illustrated in the said Fig. 4, the body of the spring being coiled beneath the shoulder and outside' the strips constituting the back of the frame. The back-frame extends upward through the slot or groove 12 in each of the guides, and is of sufficient thickness only to slide freely downward in the said groove, for instance, from the center of the guide to its rear end; and the plates 14, sliding in the U-shaped castings of the guides l1, are attached to the back-frame, as illustrated in Fig. 1, the preferred means of attachment being to secure ablock 20 between the strips of metal constituting the back- IOO frame, and projecting one end of said block forward from the frame, the said forwardlyextending end of the block being riveted or otherwise rigidly secured to the plate, as shown at 21 in Fig. 2.

The coil of the spring 19 is madeto engage with the inner face of the seat-frame, and one end of said coil is secured to the said frame in any suitable or approved manner. The pivotal attachment of the back-frame is eiieeted by passing a pin or bolt 22 through the seat-frame from the outside, through the coil and also through the extremities of the back-frame, the inner end of the' bolt or pin being threaded and screwed into a threaded aperture produced in the upper end of a preferably angle-bracket 23, (illustrated in deta1l in Fig..5,) the members of which anglebracket are rigidly attached by screws, bolts, or equivalent fastening devices to the inner face of the seat-frame below the spiral spring of the back-frame, as shown in Fig. 4; or if the seat-frame is not suiiiciently deep to permit of this attachment an offset is formed upon the said seat-frame to receive the bracket. The tendency of the spring 19 is always to support the back in the perpendicular position shown in Fig. 1, and when the back is carried rearward to any point and not secured the said spring is suiiiciently strong to restore the back to its normal positionthat is, its upright position.

As a means of securingA the back in various inclined positions, I employ a latch in connection with the sliding plate 14. This latch or locking device is contained in the armsof the chair, which arms are hollow and consist of a rod 24, passed through the arms from the front to the rear, the inner end of which rod is connected with a bell-crank lever 25, fulcrumed in the guides 11 forward of their center, as shown in Fig. 1, which bellcrank lever has attached thereto at its free end a pin 26, so located that it will enter into one of the apertures 15 contained in the sliding plate as the plate is drawn up'- ward and carried rearward by the manipulation of the back of the seat: The rod 24 is controlled by a spring 27, coiled around the same within the arm, and bearing against a suitable collar upon the rodvand the stud 28 within the arm through which the rod passes. The said spring so acts that normally the free end of the bell-crank lever 25 is kept in contact with the sliding plate 14. The rod is manipulated through the medium of a push-button 29, secured upon its outer extremity, the ends of which buttons constiy tutethe end iinish of the respective arms;

of each guide may. form a continuation ot each arm, the forward portion of` the guide containing the slide being f an independent piece, and secured in place in any approved y v manner known to the trade. In every event, however, the rear portion of the guide constitutes rear arms for the support of the back when said back is thrown rearward.

In operation, when the person is seated in the chair and desires to slide the back rearward, the buttons 29 are pressed inward,

and pressure exerted upon the back until it is carried to the desired position, whereupon the buttons 29 are released and the bellcrank lever brought in contact, as it normally is, with the sliding plate 14. The pin 26, integral with the said lever, will then enter the first convenient aperture in the plate, and thereby retain the back rigidly in the position wherein it is placed by the operator. To restore the back to its normal or perpendicular position, the buttons 29 are pressed inward, releasing the plate from contact with the bell-crank lever, whereupon as soon as the back of the chair is relieved of the pressure of the back of the operator, the spring 19, acting automatically, forces the back of the chair upward.

. Having thus `described my invention, I claim as new and desire to secure by Letters Patent- 1. In a reclining-chair, the combination, with a seat-frame 10,-a semicircular guidell, secured to the upper surface of the said seatframe at each side provided with a slotor groove 12, extending from end to end, a backframe 16, pivoted to the seat-frame at the center of the curve of the guides, and a spring 19, controlling the said'back-frame, of an apertured segmental plate 14, adapted to slide in the grooves of the guides andsecured at one end to the back `of the frame, an elbow-lever 25, pivoted `in each guide, provided with a pin 26, capable of entering the apertures 15 in the sliding plate, and a rod 24, secured at one end of said elbow-1ever and extending longitudinally through the arm of the chair, a knob29, carried on its outer end, and a spiral spring coiled around the rod within the arm and adapted to bear against the shoulder 28, forming apart of the arm, substantially as shown and described.

2. In a reclining-chair, the combination, with a seat-frame, a semicircular guide secured to the upper face of said frame, one at each side, and having a groove extending from end to end, and a hollow arm attached to each of said guides, of a back-frame pivoted to the seat-frame at the center of the curve of the guides and passing upward through the groove in said guides and having apertured shoulders, a spring attached IOO IIO
