ALZAMAN Si-UVYER, OF PROVIDENCE, RHODE ISLAND.

CONVERTIBLE CHAIR.

SPECIFICATION forming part of Letters Patent No. 312,020, dated February 10, 1885.

Apgliealion filed March 3, 1834 (No model) To all whom it may concern.-

Be it known that I, ALZAMAN SAWYER, a citizen of the United States, residing at Providence, in the county of Providence and State ofRhode Island, have invented certain new and useful Improvements in Convertible Chairs;

clear, and exact description of the invention,

which it appertains to make and use the same, reference being had to the accompanying d rawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

My invention relates to reversible chairs, and is an improvement in that class of chairs that can be converted into alounge; and itconsists in the novel construction and arrangement of its several parts, all of which are hereinafter specifically set out and described.

In the accompanying drawings,Figure 1 rep resents the chair. Figs. 2 and 3 represent the lock; Fig. 4, the front plate of the lockframe; Fig. 5, the hinge; Fig. 6, the ratchet; Fig. 7, a detailed View of the ratchet and its combinations. I

My invention is described as follows: Fig. 1 represents the side elevation and principal positions necessary in changing from chair to lounge. It is madein three sections,which are numbered 1, 2, and 3, and are held together by hinges a, devised expressly for this chair. Section 1 shows seat-frame with arms I), for

hold the back 6 of chair and seatf in position. When section 1 is released from section 3, it may be turned over to the front to form the foot oflounge. (Represented by dotted linesg.) Section 3 forms the chair'back; but when released from the arm-posts it becomes the head of the lounge, and is hingedto section 2. Section 2 is the main-body frame, to which sections 1 and 3 are hinged.

The frame of the chair,when in lounge form, is so put together by use of the hingesaat the top and cross-tiesplaced at the bottom of the frame, as to leave one uninterrupted space from head to foot for the upholstery, to form one continuous bed without interference by section ties, and may contain springs like any fully-upholstered lounge.

To change the lounge to a chair: When the foot of the lounge, section 1, is turned over on section 2 to form the chair,owingto thesprings and upholstery being raised above the frame in forming the bed of the lounge, the sections 1 and 2 cannot be brought together without force. To meet this, when section 1 is turned over, as above described, comprcssinglevers d, which are provided for thepurpose of pressing down and holding the chair-seat to the main frame, drop out of the arm-posts c, and lie parallel to the lounge-head, so that when the head is raised to point (1 the ends of levers d drop into slots h in the head-frame and form a leverage on and between both back and seat, press down the seat-frame, section 1, carry the back, section 3, into position, where it is secured by looks a to the arm-posts c to form the chair, when unlocked section 3 rides back on the leversduntiltheleverage ceases at point (1. It then slips off and is held in position by ratchets t. Then the seat, section 1, may be turned over to again form the foot of the lounge, when the levers d fallintoagroove, d out into the arm-posts c for that purpose. Thus it will be seen that by one movement the seat, section 1, is pressed down to the'main frame, section 2, the head of the lounge, section 3, becomes the chair-back, and is securely locked to the arm-posts c by locks 0, while the levers (Z, in combination with the locks 0, hold allin a solid body, and keep section 1 pressed down firmly on section 2. The lever d is made in two sections-one, d, long, the other, (1 very short and are hinged or jointed. The shorter one, d is made fast to the bottom of arm-posts c, and both are let into grooves d of said post-s out of sight, except when needed.

Figs. 2 and 3 represent the lock 0 devised and adapted to the requirements of this chair, the parts of which look are represented by letters as follows: Ii; is the frame in which the parts are held. Z and m are the face-plates. m

serves to hold the lock in its mortise min armposts 9. (Represented by the dotted lines in Fig. 1.) Z is placed opposite to plate m, andis fastened onto each side of the loungehead frame, section 3, at point Z, and serves for a bite for lock -hook a to fasten to. a is the r is the pivot.

Fig.6 represents a device for placing head of lounge in position. By means of this device the head of thelounge may be raised from a slight incline to an upright position. '6 represents ratchets; s, movable rod running from one side of the frame to the other, to each end of which ratchets iare rigidly attached. tare the rod-supporters,which are made fast to the lower corner of head-frame, section 3, through which the ratchet-rod s passes. at are the guides and braces for ratchets i. care rosettes to cover ratchets, and are attached to the ratchet by means of screws. By raising the rosette the ratchets are raised in the guides u to lower the head of lounge. Rosettes '0 also serve to cover joints connecting sections 2 and 3 of the frame.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- I I 1. The combination of the chair-frame, the seat section 1, and back 3, hinged together, the seat-section being recessed, and back pro vided with catch Z and recess h, with lever d. and latch n, pivoted to the seat-frame, as and for the purposes set forth.

2. The combinatiomwith a chair'-frame,of a back pivoted thereto, a rod mounted in said back, ratchets rigidly attached to said rod, rosettes mounted on said ratchets, and catch on said ch air-frame, all substantially as described.

In testimony whereof I affix my signaturein presence of two witnesses.
