Over the front and ture of this class which is particularly simple rear edges of the upper portion of the leg and economical of construction, durable, pracmember 1 is secured, by means of screws 4, a tical, and which will not. readily deteriorate pair of oppositely disposed upright desk sup- .50 or get out f d porting members 2 and 3, respective y. These strip 8, as shown.

members 2 and 3 are metal channel irons with their channel portions receiving the edges of the leg member and extend a considerable distance above said leg member. These upright desk supporting members or channel irons are of such weight as to be readily distortable to ward and from each other, as will be described later.

Between the channel portions of the members '2 and 3 extending above the leg member 1 is supported the lower end of the desk supporting bracket 5, preferably made from a piece of board. In the web portions in the upper ends of the channel irons 2 and 3 are longitudinal slots, indicated by 2 in Fig. 1. Extending transversely through the bracket 5 in the direction of the width is a long bolt 6, which extends outwardly through the l ongitudinal slots of the members 2 and 3. The bracket 5 is rigidly heldv between the mem bers 2 and 3 by means of nuts 7 secured on the outer threaded ends of the bolt -6. To the upper end and at the outer side of the bracket 5 is secured, by means of screws 9 or any other suitable means, a desk reinforcing strip 8 which extends fore and aft, preferably at a slight angle with the horizontal, and slightly forwardly of and backwardly from the bracket 5 to the right side of the right back sup orting rail 1 of the chair 1. The desk mem er 10 is provided at its right side with a backwardly extending arm support or portion 10*, which is formed preferably as an integral or continuous part of the desk member. The member or strip 8 is secured at its upper edge to the under side and near the righthand edge of the desk member and the arm portion thereof. The desk member is supported rigidly or reinforced relatively to the bracket 5 and the strip 8 by a bracket 11 secured to the adjacent inner sides of said members.

The rear end of the arm portion 10 is reduced to the thickness of the reinforcing Over the outer sides and upper and lower sides of the arm portion 10 and the strip 8, at their rear ends, is positioned a metal. strap or clip 12 for strengthem the rear ends of said members relatively to each other. Through the strap 12 and the strip 8 extends a bolt 13 which also extends through a substantially vertical slot 1 in the back rail 1 of the chair. This slot l is considerably wider than the diameter of the bolt 13 to permit of vertical shifting of the desk and also angular shifting thereof, it being noted that the back rail 1 of the chair is inclined at a slight angle as in conventional, chair back construction.

It will be here noted that the unit construction of the desk 10 and the arm support 10 the latter of which has considerable vertical depth at its rear end which is secured adjacent the outer side of the backrail, provides a vertically adjustable desk for chairs, of

considerable strength, particularly at its free or overhanging opposite edge in case unreasonable weight is applied at said edge, as when a person is leaning thereon or thereagainst.

.Vhen desiring to tilt the desk to another position, as shown by dot-ted lines in Fig. 2 of the drawings, the nuts 7 are merely loosened up and the front end of the desk forced downwardly. The nuts 7 are then tightened against the channel members 2 and 3, causing the same to distort slightly, as shown by dotted lines in Fig. 2, the distortion of the members 2 and 3, however, being corrected again when the nuts are loosened and the desk shifted to the position shown by solid lines, by reason of the inherent spring and readily yieldable nature of the channel members in the direction of their flanges.

Though we have shown and described a particular construction, combination and arrangement of parts and portions and have made reference only to the application of our combination desk and chair for school purposes, we do not wish to be limited to this particular construction, combination and arrangemen't nor to the specific application to school chairs, but desire to include in the scope of our invention, the application of our structure to other classes of chairs and the structure, combination and arrangement sub stantially as set forth in the appended claims.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:
