FOLDlNG CHAIR.

SPECIFICATION forming part of Letters Patent No. 780,008, dated January 10, 1905. Application filed March 4, 1904. Serial No. 196,493.

To all whom it may concern:

Be it known that I, CAsrAR METTLER. a citizen of the United States, and a resident of New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Folding Chairs, of which the following is a specification.

My invention relates to an improvement in folding chairs, and has more particularly for IO its object to provide certain improvements in the construction, form, and arrangement of the several parts of a chair of this type, whereby the chair may be made extremely light and strong, in which it may be folded very compactly, and in which the back may be brought into a comfortable angle with respect to the seat when the chair is unfolded in position for use.

A practical embodiment of my invention is represented in the accompanying drawings,

in which- Figure 1 represents the chair in side elevation in its unfolded position as in use. Fig. 2 is a similar view with the chair partially folded. Fig. 3 is a similar view with the chair completely folded. Fi at is a back view of the chair in its unfolded position. Fig. 5 is a detail front view, on an enlarged scale, of the connection between the side members of the legs and seat, the parts being shown in their folded position; and Fig. 6 is a longitudinal vertical section through the same.

The side members of one pair of legs are denoted by 1, and they are spaced apart by 3 5 one or more cross-pieces 2. The members of the other pair of legs are denoted by 3, and they are connected by one or more cross-pieces 4. The corresponding members of each pair of legs are hinged together at 5, leaving a 4 greater length from the hinged connection to the lower end of the leg member 1 than from the hinged connection to the lower leg member 3 for the purpose of bringing the chair into a comfortable position when unfolded for use.

The side members of the seat are denoted by 6 and are hinged at 7, forward of their inner ends, to their respective leg members 3 at points about midway between the hinged connections 5 and the upper ends of the said leg 5 members. These two hinged connections 7 are preferably formed by a cross-rod, the ends of which project beyond the side members 6 of the seat. Each of these seat side members 6 has a sliding hinged connection with the up 5 5 per end of the leg member 1, in the present instance by providing the side member 6 with a traveler 9, within which the cross-bar 8, which forms the, hinged connection between the two seat side members and the two leg 69 side members 1, is fitted to travel. The side members of the back are denoted by 10 and are connected. by one or more cross-pieces 11. The lower end of each of these side members is hinged at 12 to the inner end of its come 5 sponding seat side member 6, the lower end of the back side member being extended a short'distance forwardly to permit the seat and back to be folded into parallel planes. The upper end of the leg member 3 has aslid- 7 ing hinged connection with its side member 10 of the back by providing a sleeve 13,which embraces the said side member 10.

l Vhen the chair is unfolded into position for use, the back will be brought into a plane at substantially right angles to the plane of the seat and at a forward angle with respect to the plane of the pairof legs to which it is connected, thus bringing the back into a comfortable position with respect to the said seat.

l/Vhen the chair is folded, the two pairs of legs and the seat will all be brought into the same transverse plane and the back will be brought into a parallel plane offset therefrom. Thisis permitted because of the sliding hinged 8 5 connection between one pair of legs and the back and between the other pair of legs and the seat.

In the present instance I have shown the side members of the legs and the seat as being 9 formed of angle-iron construction and the side members of the back of metal-rod construction, the cross bars or slats, other than the bars 7 and 8, being formed of wood or other suitable material, the said bars 7 and 8 being of metal-rod construction.

WVhat I claim as my invention is- 1. A chair comprising two pairs of legs hinged together, a seat hinged to one pair of legs and having a sliding pivotal connection With the other pair of legs and a back hinged to the seat and having a sliding pivotal connection with the first-named pair of legs.

2. A chair comprising two pairs of legs hinged together, a seat hinged to one pair of legs and having a sliding pivotal connection with the other pair of legs and a back hinged to the seat and having a sliding pivotal connection with the first-named, pair of legs, the parts being so connected as to permit the two pairs of legs and seat to be brought into one plane and the back into a parallel plane oifset therefrom when the chair is folded.

CASPAR METTLER.
