UNITED STATES 1,721,1 4 PATENT 'OFFlCE EiF JoHN o. NEWELL AND FRANK aEnrArH, or Melina stra t, oK'LAHoM FOLDING HAIR; p

This invention relates to folding chairs.

Objects of this invention are to provide a novel form of folding chair which is made primarily of angle iron and strap iron and which is so constructed that it will fold flat in a very compact manner.

Further objects are to provide a folding chair which is formed in such a manner that it is practically indestructible, and is extremely rigid and will stand an immense amount of abuse without deterioration.

Further objects are to provide a folding chair which may be very cheaply produced, which lends itself readily to quantity production, and which is of pleasing and attractive appearance.

An embodiment of the invention is shown in the accompanying drawings in which:

Figure 1 is a sectional view through the chair corresponding to a section on the line 11 of Figure 2;

Figure 2 is a sectional view on the line 2-2 of Figure 1.

Referring to the drawings, it will be seen that the chair comprises a pair of side bars 1 formed of angle iron. These side bars pivotally carry angle irons 2 which support the seat. The seat is preferably formed by means of a plurality of spaced slat-like members 8 secured to the angle irons, and these slat-like members may, if desired, be formed of wood or metal.

Upholstery may be employed, if desired, although for outdoor use, the seat, as shown specifically in the drawings is preferred. It isintended primarily for tourists or outdoor use and will withstand the usual severe strains.

The seat is provided with a transverse brace rod 4 adjacent its forward portion which is securely attached, to the angle irons 2. Further, the angle irons 2 are provided with elongated slots 5 for a purpose hereinafter to apear. p The side rails 1 are spaced apart at their upper ends by means of a channel iron brace 6, and this brace is preferably slightly curved, as indicated in Figure 1, so that it dips down in its central portion. The side rails 1 are further provided with an oflset strap iron brace piece 7 which acts as a stop for the seat when the chair is folded. This transverse member 7 or stop is set rearwardly of the outline of the side rail 1, as shown in Figure 1. The side rails are further joined adjacent their lower portions by means of a transverse strap Hon 8 which forms 1n effect a rung.

' The lower ends of the angle iron side rails have their outer flanges inturned as indicated means of a transverse portion 18, as shown in Figure 1.

In using the chair, it is extended as shown in Figure 1, and it will be seen that the chair is securely braced and furnishes a comfortable support for a seated person. When it is desired to fold the chair, all that is necessary is to rock the seat upwardly, the seat being received between the siderails 1 and resting against the offset transverse stop 7 In rocking the seat upwardly, the strap iron rear legslO rock forwardly and pass between the side rails and contact with the stop 8. The seat is thus folded into a very compact formation, substantially flat, and occupying a small amount of space.

Due to the peculiar manner in which the seat is formed, it is extremely rigid and will withstand an immense amount of abuse without deteriorating.

Although the invention has been described in considerable detail, such description is intended as illustrative rather than limiting as the invention may be variously embodied and as the scope of such invention is to be determined as claimed.

We claim:

In a chair of the class described, a pair of side bars of angle iron operatively disposed in an incline plane, a transverse strap iron connecting the side bars at their lower ends, a channel iron brace connecting the side bars at their upper ends, an offset strap brace attached to the side bars at a point between their centers and the upper ends, a pair of parallel angle irons operatively disposed in a horizontal plane and having their inner ends pivotally connected to the side bars upon their inner faces and having longitudinal slots at their inner end portions, a transverse brace rod connecting the outer ends of the parallel angle irons, a plurality of slot-like members arranged upon and connected to the horizontally disposed portions of the parallel angle irons, strap iron brace members normally disposed in an incline plane across the side bars and pivotally connected thereto intermediate their ends, a transverse portion con- Y necting the lower ends of the strap iron brace members, and a transverse rod connecting the upper ends of the strap iron brace memhers With the ends of the rod movable in the 1 slots in the parallel angle irons.

In testimony that We claim the foregoing We have hereunto set our hands at McAlester, in the county of Pittsburgh and State of Oklahoma.
