CHAIR.

Specification of Letters Patent.

Patented Dec. 19, 1995.

Application filed March 1, 1904. Serial No. 196,107.

To all whom it may concern:

Be it known that I, CAsPAR M.WAGNER, residing at Chicago, -in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Chairs, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in chairs, and has for its object to produce a strong and durable folding chair that can be readily and quickly opened and closed and when closed or folded will occupy but very little space. I accomplish this object as illustrated in the drawings and hereinafter specifically described.

That which I believe to be new will be pointed out in the claim.

In the drawings, Figure l is a side elevation. Fig. 2 is a rear elevation, and Fig. 3 is a side elevation with the chair in its closed or folded position.

Referring to the several figures of the drawings, in which corresponding parts are indicated by the same reference-letters, A indicates a seat-frame rectangular in shape, which may be provided with a central seat-section of wood or leather or other desired material.

B C indicate a pair of supporting-legs for each side of the chair, the leg B of each pair being secured at its upper end to the side of the seat-frame near the forward edge of such seat-frame by a pivot a.

- 6 indicates a pivot connecting the two legs B and (J together.

D indicates a back-frame secured by pivots c to the sides of the seat-frame A near the rear edge of such seat-frame. As shown, the side bars of the back-frame D are extended downwardly a considerable distance below the seatframe, and their lower ends come in contact with and bear against the upper edges of the legs B.

It will be observed that the legs C of each pair are longer than the legs B, which is to enable such legs C to project some distance above the seat-frame and alongside the outer faces of the side bars of the back-frame, to which side bars they are attached by pivots d.

6 indicates an ordinary cross-bar secured between the side bars of the back-frame just below the seat-frame, and f g indicate similar cross-bars secured between the legs B.

Each side bar of the back-frame is provided I with a widened portion just above the seatframe, and at these widened portions the said side bars are so curved as to bring the forward edges of their downwardly-extending parts considerably in advance of the forward edges of their upper portions, and by this construction I am enabled to effect a'very close folding of the chair, as a whole much closer, in fact, than if the forward edges of these bars were straight from end to end, for, as is evident from an inspection of Fig. 3, where the chair is shown in its folded position, the curving referred to permits the upper portion of the side bars of the back-frame to lie close against the pair of legs B, while the remaining portion of the side bars lies directly in line with the legs B and C.

When the chair is in use, it is evident that the greater the pressure that is brought to bear against the back-frame the greater will be the force exerted by the lower portions of the side bars of the back-frame against the legs B, such legs acting as a positive stop against the further movement of the back-frame. The pair of legs C being pivoted to the back-frame at some distance above the upper surface of the seat-frame also act to furnish a considerable support to the back-frame, so that with such back-frame supported both above and below the seat-frame, as described, it will furnish a very strong support and withstand great backward strains that may be imposed upon it by the user.

When the chair is to be folded up into the position shown in Fig. 3, the back-frame D is to be turned forward, and as all of the connections between the parts A, B, C, and D are pivotal connections a turning on all such pivotal connections will. take place, with the result that as the back-frame is turned to lie with the inner edges of its side bars against the edges of the short legs B the long pair of legs C will lie parallel with and against the shorter pair of legs B, with which legs the back-frame D will also be parallel. When the chair is completely folded, the extensions of the side bars of the back-frame will be in direct line with the legs C and the seat-frameA brought into the position indicated in dotted lines in Fig. 3. It will thus be seen that not only is a very strong and rigid folding-chair provided, but the construction is such that when the several parts of the chair arefolded together they will occupy an exceedingly small space, the space, indeed, being, as is clearly apparent from Fig. 3, only equal to the combined width of the back-frame and the pair of legs attached thereto.

That which I claim as my invention, and desire to secure by Letters Patent, is

In a folding chair including a back-frame having side bars provided with an intermediate offset, a seat-frame having its rear end pivotally connected to the side bars and arranged between the latter and below the OH- set, a pairof short legspivotally connected to the side edges'of the seatvframe in rear of the front edge of the latter, and a pair of long legs pivotally connected to the sidebars of the back-frame at the offset, and to the short legs, the long legsv being outside the short legs, seat-frame and side bars of the backframe, and the short legs, seat-frame and long legs when folded being in longitudinal parallelism with the back-frame, said short legs contacting with one end of the back-frame for holding-the chair in an open position,
