SCHOOL-CHAIR.

Specification of Letters Patent. Patented. Feb, 27, 1912.

Application filed February 17, 1915. Serial No. 8,707.

new and useful Improvements in Sch0ol'-' Chairs; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My invention has for its object to improve the construction of school chairs, and more generally the class of chairs embodying a desk portion in conjunction therewith, for supporting a book or other article. More particularly the invention has for its pur pose to provide a desk portion or arm that is removable from its operative position and adapted to be conveniently held beneath the seat of the'chair when not in use, in such a manner as to permit of its ready'removal and at the same time present a neat and sightly appearance. To these and other ends the invention consists in certain improvements and combinations of parts, all as will be hereinafter more fully described, the novel features being pointed out in the claim at the end of the specification.

In the drawings:

Figure 1 is a side elevation showing a chair equipped with a preferred embodiment of the invention;

Fig. 2 is a front elevation of the same with the desk portion in full lines beneath the seat of the chair, and in dotted lines in its operative position;

Fig. 3 is a vertical sectional view with the desk portion beneath the seat;

Fig. 4 is a sectional view on the line 4 a of Fig. 1; p

Fig. 5 is an enlarged sectional view on theline 5"5 of Fig. 1, and

Fig. 6 is a detail view.

Similar reference characters throughout the several views indicate the same parts.

The chair of the present embodiment comprises a frame including a back portion 1, legs 2 and a seat portion'3.

Arranged on the frame, and preferably at.- tached to one of the side pieces 4 is a tapered socket which is constructed of sheet metal and comprises an inner plate 5 and an outer plate 6, the latter having flanges 7 which are engaged by the overlapping portions 8 of the inner p ate The outer plate bowed inwardly at 9 thereby forming a pair of tapered recesses 10, the sides-11 of the outer plate converging from top to bottom as shown in Fig. 1. The desk portion or arm includes a table 12 which lies normally in a substantially horizontal position, when in its operative po-) sition as shown in Fig. 1. The table 12' carries a standard or leg 13 preferably formed of sheet metal and including a tapered end portion 1 1 which engages the socket on the frame and includes a pair of hollow ribs or enlargements 15 which engage the tapered recesses 10 of the socket. This construction affords an extremely eflicient arrangement that enables the desk portionto be held quitev rigidly. 16 is a sheet metal brace arranged between the standard 13 and the table 12.

When the desk-portion is not. in use, it is desirable to remove it and preferably to house it beneath the chair so that it will be readily accessible and at the'same time not in the way. To this end I provide a recess in the frame of the chair beneath the seat, andpreferably formed at the front. The recess in the present structure is formed by the front legs, and cross pieces 17 and 18, the

former being arranged adjacent to the bottom of the chair seat, while the latter is secured between the legs and includes an up wardly projecting flange 19. Retaining means are provided to hold the desk portion and to this end a lug 201s attached to the chair seat and arranged to engage the front of the table of the desk portion when the latter is positioned as shown in Fig. 3, while 21 is a movablecatch which also engages the front of the table 12 when positioned as shown in Figs. 2 and 3. When the catch 21 is turned a quarter of a turn, it releases the.

desk'portion which canthen be removed and positioned in the socket for use. The desk portion may be held beneath the seat by retaining means other than .the recess and cooperating fastening devices which have been described, the ehief'purpose of the improvement being to provide for housing the desk portion beneath the seat so that it will not interfere in any way with the ordinary use of the'chair when the desk portion is not being utilized.

The construction described can be economieally manufactured, and is characterized by comparatively great strength and rigidity,

all of which is anessential and most desirable feature in connection with chairs of this type Which are subjected to such constant pair of tapered recesses, a removable desk and rough usage, and must stand long 'conportion and a standard on the desk portion tinued and hard strains Without impairing including a pair of tapered hollow ribs havtheir efficiency and usefulness. Another iming engagement With the aforesaid recesses 5 5 'portant advantage of the invention is that it and formed by bending a piece of sheet metal affords practically two chairs in one, Which upon itself at its edges.

is susceptible of use either for study Writin or for rest, or other purposes. 7 b7 HARRY LANGSLOK'V' I claim as my invention: lVitnesses: O The combination W1th the frame of a C. I. LATTIG,
