ll') all whom it may concern:

Be it known that I, J osnrn LANDKAMER, a citizen of the United States, residing at WVilliamsport,in the county of Lycoming and State of Pennsylvania, have invented a new and useful Adjustable Chair, of which the following is a specification.

My invention is an improvement in adjustable chairs, and has for its object to provide a recliningchair comprising a seat, back, and foot-rest all pivotally connected to and swinging independently of the su1:)portinglegs of the chair and adapted to accommodate themselves to the position naturally assumed by the body of the user instead of the user arranging his position with reference to the inclination of the parts comprising the chair, the various parts of the chair practically balancing each other.

My invention consists of the novel features of construction and combination of parts hereinafter described, particularly pointed out in the claim, and shown in the accompanying drawings, in which Figure 1 is a perspective view of a chair embodying my improvements. Fig. 2 is a side elevation of same, the parts being in their normal position. Fig. 3 is a side elevation, the parts being in the position assumed when a person reclines in the chair. Fig. 4: is a perspective view showing the head-rest and means for adjusting the same. Fig. 5 is a detail perspective view showing the rear of the chairframe. Fig. 6 isasection through the bracket seen in Fig. 5. Fig. 7 is a perspective view of the forward portion of one of the chairarms. Fig. 8 is a detail view of the standard supporting the front portion of the chair-arm. Fig. 9 is a perspective view showing in outline the upper end of the foot-rest hanger pivoted to the side of the chair-seat. Fig. 10 is asimilar view of the upper end of one of the front legs of the chair. Fig. 11 is a detail view, partly in section, showing the manner of hinging the footrest.

In the above-described drawings I have shown my improvements in connection with achair having rockers. It will be understood,

however, that the parts to be now described may be combined in a chair without rockers, if so desired.

On the rockers A are mounted the front and rear legs B B, and the legs I3 are cut away at their upper ends, as shown at B and notched in front adjacent the rocker, as at B. The legs B are pivoted at their upper ends to the sides of the chair-back C at a pointabove the seat U. The seat is hinged to the back of the chair at (J and the sides of the seat are pivoted adjacent the front of the seat to hangers I), as at C", which extend above the seat, and in turn are pivoted to the front legs of the chair adjacent their upper ends, as shown at I), the hangers being cut away or reduced at their upper ends, as shown at D said cutaway portions lying opposite the cutaway portion B of the front legs, and between the two are pivoted the lower ends of the arm standards E. The lower ends of the hangers D are connected by a cross-bar D, the ends of which extend through the hangers and engage the notches B when the parts are in the position shown in Figs. 1 and 2.

A foot-rest D is hinged at D to the bar D in such a manner that it can be folded up against the bar, if desired, as shown in Fig. 11. Brace'bars I) are also employed to complete and strengthen the hanger-frame. The

upper ends of the standards E are threaded and fit into balls E, which are arranged in metal sockets E, secured to the under side of the chairarms adjacent their front ends. These chair-arms F rest against and are hinged to the sides of the chair-back, as shown at F. A head-rest G- is secured to the upper end of the chair-back by the hinges G. Brackets H H are secured to the rear of the chair-seat and head-rest, respectively, and rods H and H are pivoted to arms of the respective brackets, the adjacent ends of the rods being connected by a turnbuckle H.

From the above it will be seen that the seat 0' is hinged at the rear to the back C, which is pivoted to the rear legs of the chair above the seat, and that the front portion of the seat is pivoted to the hangers D, which are pivoted to the front legs of the chair at a point above the seat. The seat is thus pivotally adapted to receive said balls, a back pivoted between the rear legs and extending below the upper ends of said legs, a seat hinged at the 5 rear to the back and pivoted at the front to the hangers at points below the upper ends of the front legs, the said side arms being hinged at their rear ends to the back, and a foot-rest carried by the hangers.
