' SCHOOL OR OTHER DESK.

SPECIFIGATI ION formingpart of Letters Patent No. 730,973, dated J'une 16, 1903.

Application filed July 8, 1901. Serial No, 67,438- (No model.)

To all whom it may concern: g

Be it known that we, CHARLES \VILLTAM ROBBINS and SEPTIMUS FRANK POYNOR, subjects of the King of England, and residents of No. 83 St. Peters road, Leicester, in the county of Leicester, England, have invented certain Improvements Relating to School or other Desks, of which the following is a specification.

Thisinvention consists of improvements relating to school and other desks, and has for its object to render such desks readily adaptable for various purposes-i. 6., by means of the double top and the end plates the desk may be used as a reading-book holder, an alinable desk for writing purposes, a drawing-board for free-arm drawing, a blackboard, slate, or a fiat table, the desk being rendered suitable forthe several purposes by lifting or moving the top board and adjusting it to any point in the width of the fixed board, the end plates serving to retain the top board in the desired-position. The face of the top board is coated with a preparation which renders it a suitable surface for working upon with chalks, pencils,or color. The top board is, moreover, adapted to lie flat, when desired, and may overlap the front of the fixed board or desk.

The'invention will be understood upon referring to the accompanying drawings, in which Figure 1 is a perspective view of a set of right-hand end plates which, together with the left-hand end plates, constitute the adjustment device forming part of this invention; and Fig. 2 is a sectional end elevation of the plates shown inFig. 1. Fig. 3 is aperspective view of a complete. desk embodying the features of this invention, the top board being in the approximately upright position suitable as a drawing-board. Figs. 4., 5, and 6 are left-hand end views of the desk, representing the top board in the positions as a reading-book holder, an alinable desk for writing, and as a fiat table, respectively.

Like reference characters indicate similar parts throughout the several figures of the drawings.

Referring to Fig. 3, it will be clearly seen plementary board B and the plates C and D 'G G and F F passing through the holes DD and C C, respectively, and the plate C is provided with a projection C to rest within the groove D formed between the projecting strips D D of the plate D, and the movable top B may be adjusted to any point along the top A between the vfront edge thereof and the back strip B. As seen most clearly in Fig. 1, the rear part of the bottom projecting strip D 'is cut away, so that the top B may be turned face downward onto the top Ainto the position shown in Figs. 4:, 5, and 6.

When used as an alinable writing-desk, the top B may be drawn forward over the top A, as in Fig. 5, or until the projection C abuts against the edge of the projecting strip D. It will be readily seen that when the top board B is in its approximatelyvertical position, with the projection C within the groove D it is impossible for it to be tipped forward face downward either wilfully or accidentally.

To slightly elevate the front edge of the top B, so as to hold the latter in a perfectly horizontal plane to enable the desk to be used for meals or other purposes in which the said top is required to be-in ahorizontal position, we provide an eccentric or equivalent means E at each end of the top board A, which is pivoted on a screw E and adapted to be turned up to support the top B when desired.

It will be understood that our top or supmay be readily applied to existing single-top desks, and, moreover, we may construct a desk with a movable top B and without the fixed top A by screwing or otherwise affixing the plates D to the tops of the standards A A.

We preferably make the end plates C D of malleable cast-iron and the top boards A and B of well-seasoned pitch-pine.

\Vhat we claim isno In a double-top desk, an auxiliary 0r snp- I allow the top 13 to be superimposed upon the plementary movable adjustable top B protop A, substantially as described. vided with a plate 0 on each end thereof In testimony whereof we have signed our each of said plates 0 having projections 0 names to this specification in the presence of 5 thereon at a right angle thereto and a fixed two subscribing witnesses.

top A provided at each end with plates D CHARLES WILLIAM ROBBINS. and strips D gD thereon, said projections C SEPTIMUS FRANK POYNOR. being adapted to bind between the strips D Witnesses:

D to hold said top B approximately vertical T. S. SHOULER,

to or be disengaged from said strips D D to F. WEST.
