WILLIAM E. WHITE, OF CHICAGO, ILLINOIS.

COLLAPSIBLE CHAIR.

Application filed February 9, 1923. Serial No. 617,949.

To all whom it may concern:

Be it known. that I, WILLIAM E. WHITE, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in a Collapsible Chair,

of which thef following is a specification.

My invention relates to concrete reinforcv ing accessories and particularly to a novel chair having the function of collapsibility.

One of the principal'objects of t is invention is to provide means for supporting concrete reinforcin devices, such means being economicall y constructed and adapted to be collapsed in order that the devices may occupy a. minimum space in shipping. This invention is an improvement in that disclosed in my copending application, Serial {No. 578,575, filed July 31, 1922.

The invention will be more readily understood by reference to the accompanying drawing, in which:

Figure 1 is a side elevation of a pair of sup 'orting devices constructed in accordance wit my invention;

Figure 2 is an end view thereof;

Figure 3 is a perspective view;

Figure 4 is a side view somewhat enlarged shg wlng the article in its collapsed osition; 1 fied orm;

Figure 6 is a side view thereof: and

Figure 7 is a similar view somewhat enlarged showing the devicedn collapsed position. 1

' In Figure 1 the device is illutsrated in position, a pipe 10 being supported thereon, it being understood that a plur lity of the devices are employed in suitabl spaced relation. The chair of my invention comprises two U-shaped members, each having legs 11 and a horizontal ortion which is vertically downwardly 0 set at an intermediate point thereby providing a depijessed horizontal portion 12 and sides 13. The sides are joined to the legs by a bend 14. The space defined by theportions 12, 13, constitutes a seat for a bar or pipe. In order to form a stable structure'a ,pair of U-shaped members such as described are employed and the legs of each member are bent at a point substantially in line with the longitudinal axis of the depressed horizontal portion 12. When two of such members are assembled to 7 inclusive.

re 5 is an end view of a slighiily modiin diverging relationa rigid structure results, dependent of course u on the joining gt the contacting portions oi the two memers.

In'order to effect the desired economy of shiippmg s ace I join the two members in or er to e ect collapsibility. To that end I provide a band 15 which is bent upwardly around the depressed horizontal portions 12 which lie, side b side, in parallelism with their longitudina axes in the same horizontal plane. Thus the portions 13, 14, together with the upper ends of the legs 11 act as complementary stops and prevent undesired lateral spread of'the legs. The extent of the spread is determined by the angle of bend of the legs at the oint indicated.

The depth of the seat is a matter of choice. If for manufacturing reasons, a seat of less depth than that indicated in Figures 1 to 3 is desired, I may provide a collateral bar holding device such as shown in Figures 5 In that construction the chair is identical with that just described except as to the depth of the vertically depressed portion but I utilize a U-shaped member of fiat material having le 16 and an intermediate portion 17, which portion is clamped by means of the band 18 in proper position with the legs extending up wardly. Preferably the material of which the U-shaped member is composed is easily bendable and after a bar, indicated at 19 in Figure' 5, is in position the legs 16 may be bent over the bar by means of a hammer or other suitable tool.

The fundamental object in the constructions described is that of simplicity and econom in shipping space. These together .5

with rigidity in use and vertical strength under load adapts the device for general use wherever a relatively high chair is required.

The construction is ca able of rather extensive modification and I do not wish to be limited except as indicated in the appended claims;

I claim:

1. In a chair, the combination of a pair of U-shaped members providing four diverging legs, the intermediate portion of ,each U-shaped member being vertically depressed to provide a seat, and means for pivotally joining the horizontal depressed portions of I the two members, the portions of said members above the pivot being an ularly disposed relative to said legs and acting as portion and of the portions of said legs above the depressed portion being disposed at an obtuse angle to the plane of the legs which form a part of said member, and means for pivotally-joining the parallel adjacent horizontal depressed portions.

3. In a chair, the combination of a pair of U-shaped members providing four diverging legs, the intermediate portion of each U-shaped member being vertically depressed to provide ahorizontal portion below the upper extremity of the member, and a band for joining the horizontal portions of said members, the portions above said pivot acting as complementary stops to limit the lateral spread of the legs.

4. In a device of the class described, the combination of a pair of wires bent into U-shape providing four laterally diverging legs, the intermediate portion of each of U-shaped members, the horizontal p'ortion of each U-shaped member being vertically downwardly deflected at an intermediate point to provide a seat, the portions of said members which constitute the legs being bent at a point substantially in line with the bottom of said seat whereby When said members are assembled the upper portions are in contact and the legs of the respective members diverge from the point of bend of the legs, and means for pivotally joining the bottom portions of the offset material whereby said legs may be permitted to swing into arallelism.
