Specification of Letters Patent.

Patented Aug. 9, 1921.

Application filed January 23 1920.. -8erla1 1T0. 353,476.

T all whom, it may concern:

Be it known that I, RUDOLPH G. Somme,

- a citizen of the United States, residing at Woodbury, in the count of Gloucester and it has more particular reference to that type of seat or chair which is made entirely or substantially so of metal, and it has forits main object 'to provide a seat or chair which can be folded u into a compapt space or can be romptly changed from a folded condition 0 an open one and in which latter position it constitues a firm and reliable support.

' A further object of this invention is to provide a'folding seat or chair which is absolutely sanitary in every respect and which when employed or used in ublic parks or exposed to open air con itions it will rapidly dry should it be rained on or otherwligse become covered with moisture or the li e.

Still further the invention comprehends the provision of a seat or chair which is simple and ,cheap to manufacture and which has no partswhich are liable to get out of order or become easily damaged.

With these and other objects in view my invention consists essentially in the novel features of construction, combination and arrangement of the various parts hereinafter fully described and more specifically defined by the appended claims.

Iln the further disclosure of the invention reference is to be had to the accompanying sheet of explanatory drawings constitutin .1 part of this specification and in which llke .characters of reference designate the same or similar parts in all the views.

Figure --l is a fragmentary front elevation of a seat or chair embodying my present improvements, parts being broken away or in section to better illustrate the underlying structure.

Fig. --2 is a similar fragmentary side View.

Flg. -3 1s a plan view.

Fig. 4- is a fragmentary sectional plan taken approximately on the line 4-4 in Fig. 2, and drawn to an enlarged scale for the sake of clearness.

Fig. 5 is a fragmentary detail view to an enlarged scale of one of the seat supporting members and its associated parts.

Referring to the drawings the numeral 10 deslgnates the seat frame proper and it is preferabl made of angle section metal with a rounde angle or fillet portion 11', so that no objectionable edge is resented to the user. This frame 10 may e of any desired contour in plan but I- have illustrated it as substantially square, and it will be obvious that it may be fashioned from a length of angle metal and have the ends welded; or' it may be formed as a stamping in one piece. Adapted to repose snugly on the frame 10 IS the seat 12 appropriately consistin of a sheet metal stamping having radial epressions or grooves 13, connecting with a central opemng or hole .14 so"that rain or the like drains rapidlyv off the seat when left exposed, It will also be noted that the grooves 13 serve to stiffen or maintain the seat in proper shape and prevent warping. ThlS seat 12 is preferably held in place on the frame 10, by depending turn buttons 15 which firmly grip the underside of the horizontal flange of said frame 10, and formed integral at the rear thereof are hinge members 16 between which is ivoted the back 17, conveniently formed rom metal stamping 18, to which is secured a wirework backing 19, and said back is provided at its lower edge with a depending lip or flange 20 which when the seat is in use rests on the rear part of the frame 10 and firmly supports the back 17 in slightly inclined rearwardly disposed position.

The legs or supporting members each include an angle section 21, which is hinged at its upper end to the inner depending flange of the seat frame 10, by strong hinge members 22, appropriately riveted thereto at 23, and the lower ends of the sections 21,

- are cut at the angle and one or both flanges turned transversely thereto to constitute solid feet 24;. The side rails are formed of angle sections 25, and they are rigidly secured to the legs 21 as by rivets or the like 26, and thus it will be seen that each side pair of legs are firmly braced together. The front and rear rails are made of angle sections 27, 28, which are hinged to the legs at 29, 30 respectively and the ends are cut or otherwise formed to abut and overlap at 31, while a pin 32 is provided on the section 28, with wh1ch cooperates a bayonet slot 33,

obvious that the fol ing up on the section 27, whereby the parts are locked-in rigid relation when the seat is folded out for use and as will be clearly understood on an examination of the drawings, and it is to be further remarked that Bracing wires of a more or less flexible nature are threaded through holes 36, in the frame 10, and secured to pins 37, on the legs 21 to aidin securing a more rigid bracing of the entire structure and it will be seen that by Jtheir flexible nature they do not interfere inany way with the folding up of the seat when not in use.

From the foregoin description it will be of the seat or chair is simply and expeditiously effected by knocking the front and rear rails 27, 28, upwardly whereby the joint is broken be tween the pin and slot connection 32, 33, whereupon the legs 21, can be folded down snugly within the frame 10. Furthermore the back 17, can be folded down compactly on the seat 12, which results in the seat presentin an exceedingly compact and neat exterior or storage or packing purposes, on the other hand it will be conceded that the setting up of the seat or chair from by my invention I provide a simple, cheap .being and very compact, and serviceable sanitary seat or chalr, and while I have described a preferred construction it will be obvious that slight changes. may be made in the shape and'form of the several parts without departing from the essential features, such changes and other combinations however limited by the scope of the appended claims. 7

Having described my invention what I claim as new and desire to secure by Letters Patent is 4 1..A sheet material chair seat having a central ,opemng and also having radial depressed stifi'emng portions forming channels communicating at their inner ends with said central opening.

2. In a chair, the combination of a rectangular open frame of angle iron, hinges having members fixed to the pendent portions of opposite bars of the frame, and

pairs of legs fixed with res set to the other members of the hinges, te -"legs of each i pair being connected together, and being arranged when not inuse to be nested in the angle iron frame, with a seat superimposed on the frame and having pendent turn buttons detachably arranged with the horizontal portions of the frame bars, and a back hinged to the seat and having a pend-v ent portion adapted to bear against the frame to maintain the back in working position.

In testimony whereof I aflix my signature.
