2'5 of the sliding frame. By this construction the table 28 may be adjusted at any angle desired by the occupant; it may be set in the position shown in Fig. 1 to be used as a reading desk or it may be lowered into a horizontal position upon the supporting member 17 (such as shown in dot and dash lines F ig. 8) to be used as a writing desk or for any similar purpose. When the table is in the position just described, the rack bar 31 will be folded up beneath the supporting member 17 and in a position parall'el to the table 28, the hook 312 thereon being located within the slot 34 of the bracket 33 thus holding the rack bar in position.

Upon entering or leaving the chair the clips 20 are disengaged from the upright 12 and the entire desk portion is swung, to one side upon the hinges 15, as shown in Fig. 2, thus allowing any one to enter or leave the chair. The foot rest 9 may be used either in the position shown in Fig. 1 or it may be turned.

IV hen the table and foot rest are not in use they may be folded together and slidably mounted beneath the seat of the chair where they are concealed from view thus transforming the chair into an ordinary arm chair. The table is first lowered into the position shown in dot and dash lines in Fig. 3, as hereinbefore described after which the links 22 are closed, moving the entire table and table supporting frame into a vertical position as shown in full lines in Fig. 3 after which the links 13 are closed thus bringing the entire structure into folded position as shown in dotted lines in the same figure upon the sliding frame composed of the supporting arms 8 and sliding head 6. The movable parts thus folded are then slidably moved back beneath the seat as shown in Fig. 4- of the drawings, the foot rest 9 forming a part of the box of the seat.

Although my invention has been described and illustrated as being best adapted to be applicable to either an invalids chair or a childs chair it would be understood that there are a great many other uses to which it might be applied. The table would be very useful to artists and the like where it is necessary to have a table held at an angle in front of the operator. It is to be further understood that although the drawings show the device applied to an ordinary arm chair that the particular form of chair used is immaterial it being applicable to a rocker or in fact to any form of chair.

Although the drawings and above specification disclose the best mode in which I have contemplated embodying my invention I desire to be not limited to the details of such disclosure, for, in the further practical application of my invention, many changes in form and construction may be made, as circumstances require or perience suggests, without departing from the spirit of the invention, within the scope of the appended claims.
