DESK.`

SPECIFICATION forming part of Letters Patent No. 675,171, dated May 28, 1901.

Application filed December 6, 1900. Serial No. 38,932. (No model.)

o all whom it may concern.-

Beit known that I, ROBERT MACKIE SMITH, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Desk, of which the following is a full, clear, and exact description.

This invention relates to a desk provided with a reversible top, which when in one p0- sition serves as the top of a desk to be used in the ordinary manner and which when in the other position serves as a top for use in manual-training classes or for analogous purposes. The desk is therefore a combined study and manual-training desk adapted especially for use in schools which combine manual training with mental study.

This specification is a specic description of one form of the invention, while the claim is a definition of the actual scope thereof.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side view of the invention adapted as a study or writing desk. Fig. 2 is a view of the device adapted as a manualtraining desk or bench. Fig. 3 is a fragmentary plan view of the same, and Fig. 4. is a section taken on the irregular line 4. 4 of Fig. 2.

The framing a of the desk may be of the usual or any desired construction, except that it comprises a slideway ct' at its top, just below the top of the desk. On the framing a. is fitted a stationary piece b, having grooves and recesses for the reception of pens, pencils, ink-wells, &c. The top c of the desk has one side formed plain, so that such side serves as the top of an ordinary study-desk. This side is shown up in Fig. 1. The opposite side of the top c is formed with a tray or depression c' for the reception of tools and withaplain portion c2, forminga work-bench, the face of which is preferably covered with lzinc. When the top cis turned as shown in Figs. 2 and 3, the tray c and the Work-bench c2 are upward and the desk is then adapted for manusl training.

At one end `of the top c are arranged two brackets d, which are fastened pivotally to the top by screws e or by any other suitable devices, as will be obvious to skilled mechanics. These brackets d extend downward to the respective slideways d and terminate in slides d', which respectively work on the slideways ct. At the end edges of the top c, adjacent to the side opposite that at which the brackets d are located, knobs f are fastened to the top, and these knobs are arranged to work with arms g, fastened to the framing a, and serve to hold the cover in the position in whichit is placed, thus preventing the cover from sliding down on the slideways a', the fact that these slideways are inclined making it possible for the cover to slide in the manner stated, which sliding is prevented by the arms g. When the cover is adjusted as shown in Fig. 1, the brackets d bear against the arms g, and when the top is adjusted as in Figs. 2 and 3 the knobsf bear against the arms.

To change the top from the position shown in Fig. l to that shown in Fig. 2, the upper edge of the top should be raised, which may be readily effected by grasping the knobs f. This raising movement is indicated by dotted lines in Fig. l. The top should then be completely reversed, giving it a half-turn on the fastening devices e, which it will be seen also serve as pivots. The tray c and bench-surface c2 will now be placed upward, and then the top may be slid forward, the slides d lie forward of the arms g, whereupon the rear part of the top may be dropped to engage the knobs f with the arms g and the reversal of the desk will be complete. To readjust the desk to the position shown in Fig. l, the above-described operation is sim ply reversed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- A desk, having a framing with slideways therein, slides mounted in the slideways and adapted to move throughout the length thereof, a reversible top pivotally connected with the slides at one extremity of the top, whereby upon the movement of the slides from one end of the desk to the other the top may be reversed from one of its positions to the other,

working in the slideways a until the knobs f IOO and a retaining-arm fastened to the desk :Lt I name to this speeifeationin the-presence of one end thereof and .having :L part lying in two subscribing witnesses. the plane of the top of the desk when in opr y Y elative position, the retaining-arm serving ROLERT MACKIE SMITH' to engage the end of the top of the desk to \Vitnesses: hold the parts in position.

In testimony whereof I have signed my4 EVERETT A. ABORN.
