Application filed May 10, 1915, Serial no. 27,242. nenewea'namh 2?, 1918. serial n aaaioe.

To all whom it may concern:

Be it knownthatl, LAURENTE RUPP, a citizen of the United States, resident of the bor ough of Manhattan, city and county of New York, State of New York, have invented a new and useful Improvements in Folding C hairs, of which the following is a specificaion.

This invention relates to folding chairs, and has for its object to construct such an article in an exceedingly simple and inexpensive manner; to provide means whereby the legs, back and seat of the chair may all be folded closely together so as to occupy but a small space, and be convenient for carrying in the hand, or for shipment or storing away, and when so folded that it may be fully opened for use easily and with but few motions; to provide a sliding connection between the seat and one pair of leg members, so that the seat will at all times be held in its proper relation to the legs, and still permit of the opening and closing of the chair; also to provide means for limiting the movement of the parts when opening them, and to brace said parts in their open position so as to produce an exceedingly strong and reliable article.

These and other objects of my invention are set forth in the following specification and shown in the drawings annexed hereto, the particular features of novelty which constitute mv invention being pointed out in the claims at the end of this specification.

In the drawings, which form a part of this specification, and in which similar let ters and figures of reference refer to corresponding parts wherever they occur Figure l is a central vertical section of my chair showing the same in an open position;

Fig. 2 is a similar view showing the parts in a closed position;

Fig. 3 is a front elevation; and,

Fig. 1 is a detail view of the bracket piece.

My chair comprises a seat 1, a back 2 and two pairs of legs assembled in two leg members 3, 4. The two legs forming each leg member are firmly secured together at the required distance apart by braces or crosspieces, 5, 5 and 6, the latter of which also act as a stop as hereinafter more fully explained.

The leg members 3, 4, are made to lit and work, one within the other, as shown in the drawlngs, and are plvotallv connected with each other upon pivot pins 7.

Upon the under side of the seat 1 are rigidly secured a front strip 8, a rear strip 9, and side strips 10, 11, and a wire rod 12 passes beneath the center of the seat 1, the ends of the rod being secured in openings formed in the strips 8 and 9 respectively.

A frictional member 15, having an eye 16, through which the rod 12 passes, is secured to the cross-piece 5 which is placed at the upper end of the leg members 3, in such manner that it engages with said rod tightly at all times so that there will be no looseness between the seat and leg members which will be held together without lost motion whether the chair is open or closed and so that there will be a sliding connection between them in opening or closing the chair.

To each of the side strips 10, 11, 1 secure a bracket-piece 17, having an arm 18, by screws, or bolts 19, one on each side of the chair. The leg members 4 are pivotally secured to the side strips 10, 11, upon pivot pins 20, which may also be extended through the bracket pieces 17, if desired.

Upon each side of the back 2 I secure a plate 21, which is pivotally secured to the arm 18 of the bracket 17 by a pivot pin 22. The bracket 17 is provided with an inwardly extending lug 23, upon which the plate 21 strikes and rests when the chair is opened, thereby acting as a stop to prevent undue backward movement of the back 2.

The cross-pieces 6 are so placed on the leg members 4, that the leg members 3 will strike them when the chair is opened to its proper extent, and they therefore act as a stop to prevent undue opening of the leg members. In like manner the cross-pieces nearest the pivot pins 7 on the le members 3 are extended to act as a stop for the leg members 4:.

Having now described my invention what ll claim as new and desire to secure by Letters Patent is 1. A chair comprising a seat having side strips secured beneath its outer sides, leg members pivotally secured together and to said strips, bracket-pieces having 11 wardly extending arms and secured to said strips, side plates pivotally secured to said arms, a

orFIoE.

. back secured between said side plates, and

inwardly extending lugs formed near the bottom of said bracket-pieces adapted to serve as stops for said side plates.

2. A chalr comprisinga seat 3 and a plurality of leg members all pivotally secured together, bracket-pieces secured to said seat provided With upwardly extending arms andwith lugs near their bottom edges, side plates which are pivotally secured to said arms, a back secured between said side Copies ofthis patent may be obtained for plates, said side plates being adapted to abut against said lugs when the back is in its opened position.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
