FOLDABLE CHAIR.

Specification of Letters Patent.

Patented May 21, 1912.

To all whom it may concern:

Be it known that we, NICHOLAS STOCK and JOHN N. CoRD'rs, citizens of the United States, residing in Kingston, Ulster county, New York, have invented certain new and useful Improvements in Foldable Chairs, ol" which the following is a specification.

This invention relates to foldable chairs, and has for its object to provide a chair which may be folded in compact manner so as to enable the shipment of the same to be readily and conveniently made.

The object of this invention is to provide an improved chair which can be folded into compact form and of a size one-half the height of the chair when in use.

In the accompanying drawings, Figure 1 shows a side elevation of our improved chair ready for use, with the rear legs shown in two positions, in full lines when in use, and in dotted lines when folded, Fig. 2 is a front elevation, Fig. 3 is a plan view, Fig. 4 is a side view with the back lowered, Fig. 5 is also a side view showing the parts win a position during folding, Fig. 6 is a side view partly in vertical section, showing on an enlarged scale the rear hlnge, Fig. 7 is a side view of the chair in folded position, and Fig. 8 is a detail perspective view of the plate for binding the seat and legs together.

Similar letters of reference indicate corresponding parts throughout the views.

Referring more particularly to Figs. 1, 2 and 3, the seat 10 is provided with an upholstered portion 101. The back 11 is provided with back-stays 111. The seat 10 is supported by two sets of legs, an outer set 12 and an inner set 14, which are hinged together near their middle portion by hingepins 19 passing through the legs l2 and 14. The back l1 is hinged to the legs 12 by means of hinge-pins 13, and these are arranged in position above the seat 10. The back 11 extends downwardly below the hinge 13, and the downwardly-extending portion 131 presses against the seat 10 when pressure is exerted on the back. The legs 14 are provided with a bar 17 connecting their upper ends, and this bar is movable in slots 16 of downwardly-extending plates 15 arranged at each side of the seat 10, at the lower surface of the same. The upper ends of the legs 14 are provided with meta-1 pieces secured to the legs by means of screws 18, which metal pieces assist in securing the rod 17. Strengthening stays 2O and 21 serve to hold the legs 14 in position against warping or breakage. The legs 14 are movable from the position shown in full lines to the position shown in dotted lines in Fig. 1, and the bar 17 is movable from the front ends of the slots 1G to the rear ends of the same. In order to combine the parts a plate 25 is provided, which has upwardly-extending bentover portions at 27 and 28 parallel to each 65 other and some dist-ance apart, while the part 28 has a bent-over portion 29 parallel to the main-portion 26. At the side of the main-portion 26 an upwardly and rearwardly extending portion 3() is provided, 70

which has an elongated slot 31, adapted to receive a bolt 32 passing through slot 31 and through the legs 12. The slot 31 is elongated so as to permit the movement of the extension 30 relatively to the bolt 32. The up- 75 tween the same and the downwardly-extend ing portion 131 of the back l1 said portion 28 being located at a portion that is cut out of the seat 10, as shown in Figs. 3 and 6. The bent-over portion 29 is located on the upper surface of the seat 10, close to the cut out portion, and thereby when the plate 25 is fixed to the seat 10 by means of screws 251 the seat l0 and legs 12 are securely held together with however the possibility of hinge-movement around the point32, and

also the distance of the slot 31.

The operation of our improved chair is as follows: Vith the parts in the position shown in Fig. 1, the legs 14 are pressed from the front part of the seat toward the rear of the same, while the rod 17 travels in the slots 16 and takes the position shown in dotted lines in Fig. l. Thereupon the back 11 and both leg- members 12 and 14 are pressed toward each other around the re-,100

spective pivots 13, 32 and 17, and the entire chair is folded from the position of Fig. 1 to the position of Fig. 7, taking the course shown in Fig. 5, when the back and legs approach each other as shown by the direction of the arrow and the legs 14 shift position relative to the legs 12, the tops of the legs 14 passing from a position in front of the legs 12 as shown in Fig. 5 to a position in rear thereof as shown in Fig. 7.

When the parts are folded as shown in Fig. 5, there is relative movement of the pin 32 in respect to the legs 12, the pin 32 traveling in the elongated slot 31, and by reason of this movement any cramping of the parts is prevented. By reason of the movability of the legs by the rod 17 in the slotted members 15, and the back being hinged to one set of legs, the collapsibility of the chair is,

made possible and by means of this a chair is produced which is fo-ldable into a size equal to about one-half of the height of the chair when in use.

By means of the structure described and shown, a chair is produced that aords a very secure seat and on the other hand is capable of being readily transported from place to place and therefore adaptable for many uses where the requirements of foldable chairs are imperative.

Ve have shown one embodiment of the invention, but changes may be made therein without departing fro-1n the spirit of the invention.

Having thus described our invention, we claim:

In a folding chair the combination of a set of connected outer legs, a set of connected inner legs pivot-ed to said outer legs on a fixed pivot, terminating below the plane of the outer legs and provided at their upper ends with a lateral rod, a seat provided with a horizontal slotted guide-way and with notches at its rear edge, brackets secured to said seat consisting of flat attaching plates provided with notches corresponding with the notches in said seat, with upward flanges at their rear edges, with upward fianges at the inner edges of said notches, and with upward lips on said last named flanges adapted to engage the top of the seat kand having side plates provided with slots engaging studs on said outer legs, and a back pivoted near its lower end to said outer legs above the connection of said seat and provided with a downward eXtension adapted to engage the notches in the latter for holding the back in open position, said seat and back swinging downward to fold the chair andthe outer portions of said inner legs swinging from forward to rearward position relative to the outer legs in the folding operation.

In testimony, that we claim the foregoing as our invention, we have signed our names in presence of two subscribing witnesses.
