The chairs.

The object of the invention is to provide a chair having a fabric back and seat held under spring tension to prevent undue sagging of the same.

Another object of the invention is to provide a chair of this character, in which the back and seat can be readily removed, or applied, in order to allow the fabric to be Washed or changed.

A further object of the invention is to provide a simple and comfortable chair which can be cheaply manufactured with certain details of structure and combination of parts hereinafter more fully described.

In the accompanying drawings,

Figure 1 is a vertical longitudinal sectional view of my improved chair;

Figure 2 is a sectional view, taken on the line 22 of Figure 1;

Figure 3 is a sectional view, taken on the line 33 of Figure 1;

Figure 4 is a sectional view, taken on the line 4-4 of Figure 2;

Figure 5 i a sectional view, taken on the line 5--5 of Figure 3;

Figure 6 is an enlarged sectional view, shOW- ing the spring and its attachment to the seat of the chair.

Referring now to the drawings, l represents the front legs of the improved chair, which have pivoted thereto, at 2, the obliquely arranged rear legs 3 connected together at their rear ends by the transverse bar 4. Pivotally connected to the upper ends of the front legs, at 5, are the arms 6, which extend in a horizontal direction and pivotally connected at I to the obliquely arranged back members 8. The lower end of the back members are bifurcated, as indicated at 9, and adapted to straddle a transverse bar It]. carried by the obliquely arranged rear legs 3 whereby they are pivotally mounted thereon. The back members 8, as shown in Figure 1 of the drawings, extend a considerable distance above the arms 6, and extending around the same, above the arms, is a fabric back rest I I. This back rest is, of a length to extend around the back members 8 and is provided with hems l2 and I3, in which are inserted the wire looped members l4 and I5 having the kinked portions l5 and I1, into which are hooked the ends l8 and I9 of the coil spring 29. The back rest ll, intermediate its upper and lower ends, is provided with a fabric covering 2| to receive and protect the spring 20 and hold it in its proper position.

invention relates to improvements in The obliquely arranged legs "3 extend beyond the front legs land are connected by a transverse bar 22. The back members B'are connected by-a transverse'bar-23 arranged in'horizontal 5 alinement with the bar 22. The lower ends of the front legs I are connected by a transverse bar 24 to brace the same. By this structure, it will be seen that the bifurcated ends of the back member may be lifted from the bar II] and the chair folded in a fiat position by the arrangement of the pivots I, 5 and 2.

The seat 25 i made of a piece of fabric looped around the bars 22 and 23, and provided with hems 26 and 21, into which pass the straight portions of the looped metal members 28 and 29. These members each have their free ends extending obliquely inwardly, a indicated at 30 and 3|, and are turned inwardly at 32 and 33, and have hooks 34 and 35 which hook over the straight portion 31. The hems 26 and 2'! are provided with cut-out portions 38 and 39 to expose the straight portions, so that the hooks may be readily applied. Coil springs 40 and 4| are provided with eyes through which the looped members 28 and 29 pass, and whereby they are drawn together at their outer ends. Coil springs 42 and 43 connect the inner ends of the obliquely arranged portions 30 and 3|, so as to prevent the straight portions of the members 28 and 29 from bending and also 30 to cause a greater tension on the fabric seat.

From the foregoing description, it will be seen that the back can be readily placed over the upper free end of the back sections 8. The seat can be readily removed by releasing the hooks 34 and 35 and sliding the spring 40, 4|, 42 and 43 from the members 28 and 29.

While I have shown a specific form and arrangement of spring connected member for drawing the back and seat tight, it will be understood that the same could be varied without departing from the spirit of the invention.

Having thus described the invention, what I claim is:

1. A chair, comprising front legs, inclined rear legs pivoted to the front legs and extending beyond the same, back members pivotally connected to the rear inclined legs, a back carried by the upper end of the back members, arm rests pivotally connected to the upper ends of the front legs and the back members, a transverse bar connecting the back members, a transverse bar connecting the upper ends of the inclined legs beyond the front legs, and a fabric seat extending around the transverse bars and connected to- 65 gether by a spring device.

2. A chair, comprising front legs, inclined rear legs pivoted to and extending beyond the front legs, back members pivoted to the inclined legs intermediate their ends,arms pivotally connected to the upper ends of the front legs and to the back members, a transverse bar connected to the back members, a transverse bar connecting the inclined rear back legs forwardly beyond the front legs, a seat of fabric extending around the transverse bars, and. spring tensioning means connecting the ends of the fabric.

3. A chair, comprising front legs, inclined rear legs pivoted to and extending beyond the front legs, back members pivoted to the inclined legs, arm pivotally connected to the back members and the upper ends of the front legs, a transverse bar connecting the back members, a transverse bar connecting the inclined rear leg forwardly beyond the front legs, a fabric seat extending around the transverse bars and having its ends provided with hems, loop members extending within the hems, and coil prings removably connecting the looped members.

4. A chair, comprising front legs, inclined rear legs pivoted to and extending beyond the front legs, back members pivoted to the inclined rear legs, arms pivotally connected to the back members and the upper ends of the front legs, a transverse bar connecting the back members, a transverse bar connecting the inclined rear legs forwardly beyond the front legs, a fabric seat extending around the transverse bars and having its ends provided with hems, loops held within said hems and provided with converging arms forming eyes, and a coil spring removably connecting the eyes.

5. A chair, comprising front legs, inclined rear legs pivoted to and extending beyond the front legs intermediate their ends, back member pivoted to the inclined rear legs, arms pivotally connected to the back members and the upper ends of the front legs, a transverse bar connecting the back members, a transverse bar connecting the inclined rear legs forwardly beyond the front legs, and a fabric seat extending around the transverse bars and having it ends connected by a yielding member.
