JOSEPH KITAK, OF BRIGHTON, WASHINGTON.

FOLDING CHAIR.

Specification of Letters Patent.

Application filed October 9, 1911.

Patented June 11, 1912.

Serial No. 653,548.

To all whom it may concern:

Be it known that I, JOSEPH KITAK, a citizen of the United States, and a resident of Brighton, Washington, have invented certain new and useful Improvements in Folding Chairs, of which the following is a full, true, and exact specification.

The principal object of this invention is to provide a strong and durable arm-chair, readily foldable into small compass and which, when set up, has the appearance of an ordinary non-foldable arm-chair, as contracted with folding seats or chairs heretofore known to the art.

The invention will be fully described in the following specification and shown in the accompanying drawings in which- Figure l is a side elevation of the device set up. Fig. 2 a plan view. Fig. 3 a side elevation of the device in folded position. Fig. 4 a fragmentary rear view. Fig. 5 an edgewise view of a modified form of seat.

The reference numeral 1 designates the back of the chair, 2 the arms, which are pivoted at 3 to the back 1 which has the shoulders 4. Extending downwardly into the shoulder 4 is the channel 5 into which is fitted one end of the hinge 6 which is firmly secured to the back 1 by wood screws or other suitable means. The other end of the hinge 6 is similarly secured to the edge of the seat 7. Beneath the rear edge of the seat 7 and secured to the back 1 may be the cleat 8. The forward ends of the arms 2 have the pins 10 adapted to fit into the slots 11 in the edges of the seat 7. The slots 11, it will be observed, are not cut at right angles to the edges of the seat 7 but inclined toward the front thereof so that when the arms 9. are let down into the approximate position shown in Fig. 1 the pins 10 do not exactly register with the slots 11 but have to be sprung slightly backwardly and then outwardly into the dotted position shown in Fig. 2, when the pins 1'0 may be thrust sidewise into the slots 11. The pins 10 are relatively slender and the inherent spring of the arms 2, which are preferably of wood, readily permits this slight bending or springing. After the pins 10 are received by the slots 11 the arms 2 spring back to approximately their normal positions and are held against lateral displacement by the undercut forward walls of the slots 11, as will be understood. Hinged at 12 to the under forward portion of the seat 7 are the front legs 13 which are identical with the rear legs 14. Hingedly connected at 15 to the front and rear legs 13 and 14: respectively is the brace 16. If desired the seat 7 may have the opening 17, and the undercut cleats 18 into which undercut portion may be entered the flange 19 of the chamber 20 so that the device maybe conveniently used as a toilet chair for the sick in hospitals and the like.

The rear edge 21 of the seat 7 projects very slightly beyond the plane of the pin 22 of the hinge 6, so that when said seat is dropped into approximately its position as shown in Fig. 1 the forward end of the same must be forced downwardly to bring thetop surface of the seat 7 beneath the lower edges 23 of the arms 22.

From the foregoing description it is believed that the construction and operation of my device willbe fully understood by those skilled in the art, many changes of construction from that shown and described being possible without departure from the spirit and scope of the invention, and I do not therefore desire to be limited to the particular form shown and described.

Having described my invention, what I claim as new and desire to protect by Letters Patent is The combination in a foldable chair of a rigid back and rear legs and a seat hingedly connected to said back, front legs hinged to the under side of said seat, and a brace hinged between said front and rear legs, of,

downwardly curved and slightly resilient arms having their rear ends pivoted to said back and their forward undermost edges bearing vertical pins slots in the side edges of said seat and slightly out of alinement with said pins and into which said pins are adapted to be sprung by first forcing said arms slightly outwardly and then backwardly, whereby said arms are tightly frictioned against movement with relation to said back and said seat.
