Patented May 15, 1906.

Application filed April 1,1905. Serial No. 253.335.

To all whmn it away concern:

Be it known that I, JAMES E. HANG-En, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Chairs and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in chairs; and the object of my invention is to provide a simple reclining-chair and. one that can be easily and economically made.

With this object in view my invention consists in the construction and. combinations of parts as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of a complete chair. Fig. 2 is a cross-section of the same, taken on the line 2 2 of Fig. 1. Fig. 3 is a detail showing the construction of the head-rest. Fig. 4 is a horizontal cross-section on line 4. 4 of Fig. 2 of a part of the chair, showing the means forv releasing the sliding seat. Fig. 5 is a vertical cross-section on line 5 5 of Fig. 2 of the parts of the chair, showing the means for guiding and locking the seat; and Fig. 6 is a perspective view looking down into the corner of the chair and showing the locking means.

The chair consists of the frame having two rear uprights a a and two front uprights b b, which are united by side pieces 0 and crosspieces (1. Arms 6 are provided running from the uprights I) to the uprights a on each side in brackets f. Pivoted to the uprights a is mounted the swinging back g. The back may be pivoted on a rod running from one upright a to the other, or two rods may be used, one fastened in each of the brackets f.

At the top the chair is provided with a head-rest consisting of the wire h, bent to form an elongated ellipse, the ends of the wire being fastened in the sides of the back, and a piece of canvas or similar material t runs from one of the hooks h to the other, the ends being brought through the hooks 7L and sewed over them, thus making a very cheap and flexible head-rest.

To the back 9 is pivoted, as shown at 1', Fig. 2, the seat, which consists of a substantially rectangular frame having side pieces k and cross-pieces Z. Above the seat-frame is supported a canvas cover m, which extends upward to form the support a for the back of terminate in loops passing around the rod or wire 9, and the front ends are bent over, as

shown at s, entering recesses in the chairframe, and the canvas is tightly fastened to said wires. Two of these bent wires may be used, one on each side, or a number of them arranged parallel to each other, as may be preferred. The wires 1), which support the back of the user, are arranged parallel with each other in a series and pass through loops in the canvas back or or are secured thereto in any suitable man'nen The means for locking the seat, and thereby the back, in any desired position will next be described. The side pieces of the seat each have a projecting portion it, provided with a projection a and ratchet-teeth v. The projections u enter undercut slots w in the cross-pieces d, whereby the movement of the seat is restricted and guided. The locking is effected by means of the sliding bar 00, provided with a slot y, which bar is sup ported by brackets z, secured to the front cross-piece cl, the bar a sliding freely in said brackets. Near one end the bar :1: terminates in a point 1 to engage the ratchet-teeth on one of the projections t, and the sides which surround the slot y engage the teeth on the other projection 15. The bar a: is movable freely from side to side to engage or disengage these ratchet-teeth by means of a bent wire or connection 2, which passes loosely into a hole near one end of the bar and which wire is attached to one end of the lever 3, which is pivoted, as shown at 4, in a slot in one of the side pieces 0. A spring 6 normally holds this bar in connection with the ratchetteeth, so as to lock the chair in any desired position.

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

1. In a chair, the combination of a supportingframe, a back directly pivoted on said frame, a seat directly pivoted on said back, a wire frame located in proximityto said back and seat and consisting of two parts, each part consisting of a number of parallel Wires, one .part being shaped to conform to the shape of the back, and the other part being shaped to conform to the shape of the seat, and a canvas cover for said wire frame, the ends of which cover are supported by the back and seat respectively, said Wires being secured to said canvas, substantially as described.

2. Ina chair, the combination of a supporting-frame, a back pivoted thereon and provided with a head-rest, a seat pivotally connected to said back, and a wire frame located in proximity to said back and seat and composed of two parts pivotally connected together and shaped to substantially correspond with the back and the seat respectively, said frame being composed of a number of parallel wires, and a canvas cover composed of two parts fastened to said wire frame, the upper end of the canvas being supported by the back, and the lower end by the seat, substantially as described.

3. In a chair, the combination with a supporting-frame, the front cross-piece of which is provided with undercut grooves, a seat carrying ratchet faced projections, which projections engage with said grooves, a back directly pivoted to said seat, and means for normally locking said seat, and. thereby said back, in any desired position, consisting of a sliding bar provided with portions adapted to engage said ratchet-teeth, a lever operated by the user, and a spring for returningsaid "said seat, a sliding bar provided with a slot and pointed end adapted to engage said ratchetrteeth, a lever for operating said bar and a spring for normally holding said bar in engagement with said ratchet-teeth, substantially as described.

5. In a chair, the combination of a frame consisting of uprights, side pieces, crosspieces and. arms, the front cross-pieces being provided with undercut grooves, a seat slidably supported on said: frame and. provided with downwardly-extending ratchet-faced projections shaped to engage with said grooves, a back pivotally connected to said seat and provided with a head-rest, a wire frame composed of two parts, joined together and conforming in shape to the back and to the seat respectively, anda canvas coverfor said wire frame, said cover being secured to said frame and the ends of said cover being secured to the back and the seat respectively, substantially, as described.

In testimony whereof I affix my signature in presence of two. witnesses.
