Application filed November 19, 192%. Serial No. 750,765.

lie it known that I, JULiUs L. CABLE, a citizen of the United States, and resident of Boston. in the county of Suffolk and State of Massachusetts, have invented an Improvement in Folding Camp Chairs, of which the following is a specification.

This invention relates to that class of folding' camp chairs or stools in which the bottom is of canvas or similar flexible sheet material and, more particularly, to chairs of this type which are constructed from semi-tubular metal.

In the construction of chairs of this type considerable difficulty has been encountered in providing suitable means for attaching the canvas to the metal cross bars of the chair, attachment by means of rivets being unsatisfactory and unreliable, and the object of my invention is to provide a simple and eflective means for connecting the canvas seat of a camp chair of the above type with the cross bars of the chair which will be as strong as the material of which the seat is constructed, and which is so arranged that the actual expense of construction will be no more than that of previously employed methods.

I accomplish these objects in the manner hereinafter described and as illustrated in the accompanying; drawings in which 2 Fig. l is a side elevation of a folding); camp chair embodying my invention.

Fin. 2 is a similar view showing; the chair folded.

Fin. 3 is a detail sectional view of one of the cross bars and top portion of one of the legs.

Fig. 4: is a longitudinal sectional view at line a2a2 of Fig. 3.

Fig. 5 is a sectional view of one of the cross bars.

Fig. 6 is a side view of a cross bar, partly in section.

Fig. 7 is a detail view of one end portion of a cross bar prior to assembling.

In the drawing a common type of-folding camp chair is illustrated, which comprises two pairs of legs 1 and 2 formed of semitubular metal and pivotally connected in the middle thereof, so that they may fold in the usual manner, as shown in Fig. 2.

According to my invention 1 provide a pair of

cross bars

3 and 4 for connecting the opposite legs their upper ends and a and ears on the legs.

towards each other atright angles, to form retaining flanges or lips 6. The upper end portions of the legs are flattened to form ears 7, which are adapted to enter sockets 8 at each end of the cross bars, the length of said sockets to the lips 6 and the width of said cars corresponding.

In assembling the parts above described, the canvas seat is turned over and sewed to provide with a simple form of hem 9 at each end and give the canvas treble thickness at these points. The distance between the edges of the flanges 6 is only sufficient to permit a single thickness of the canvas to extend therethrough and in assembling the canvas and cross bars the hems are drawn into the bars at either end, until the sides of the strip are even with the ends of the bars, in which position the canvas will extend between the edges of the flanges, and its hems will be retained within the bars by their engg'agament with the flanges as shown in Fig. 5. The canvas is then wound part way around each bar and the sockets at the ends of the bars are then placed on the ears 7. as shown in Figs. 3, 4, and 6. are then passed through the sides of the bars, the intervening; ears 7 and hemmed portions of the canvas, and then these parts are clamped closely together by the rivet ing process as shown in Fig. 3. As thus arranged the canvas extends from each bar about its outer side and over its upper edge, completely covering the exposed portions of the bar. The half turn, which is thus taken about each bar by the canvas, relieves the strain which would otherwise be placed on the hem, which is drawn into engagement with the lips 6, to a substantial extent. This strain is further relieved by having the end portions of the canvas firmly clamped between the sides of the cross bars The canvas as thus arranged, completely covers the sides and top of the bar and gives the chair a finished appearance, and the strain on the canvas Rivets 9 llt),

will be uniformly distributed throughout its entire width. The cross bars, oanvasand legs will also be securely hound together so that these parts will be rigidly held in the relative positions shown.

The chair may he provided with it back 10 which is pivotally connected to opposite legs.

I claim:

1. A folding chair having; a pair of semi-- tubular metal (cross bars, two pairs of pivot- :illy connected crossed i each 1 ear at its upper end extending h corresponding end portions of th re said bars respectively, the portions of the sides of each bar between said M turned to term retaining lips, 21 seat 0 sisting of textiie strip having eeeh portion extending into one of sad l between the lips thereof and between of its sides and the ears of the COEEQSDOZE'V ing pair of legs .seie strjp i havin thickened end port ons for ensgng'i the inner s legs bein i:

portions of the sides of the bars :ii'id ii'itervening ears and s "p portions together. 2. A foidingr chair having; a of seniitubular mete cross here, two me i of pivotal y connected crossed having: an ear at its upper end ext iietn'een corresponding; end portions 0; the sides ot said bars respectively, the portions (at the sides of each bar between said iegs interned to form ining lips it sent sisting of a textile snip having each end y tion extending; into one of said hers he the lips thereof and between one of and the ears of the corresponding pnii legs, said strip having thiekened end portions for engaging the inner sides or said lips and clamping bolts extending thru the end portions of said sides, and the intervening ears and strip portions to bind the same together.
