In the drawings, Figure l is a perspective view oi a shool-desk provided with a desk top or lid constructed in aceori'lance with this invention, and illustratii'ig the position of the parts when-the hook-rest is raised.

Fig. is a detail end view of the top of the desk, illustrating the position of the parts when the book-rest is not in use.

Referring to the drawings, A designates the desk top or lid, which is secured to the other portimis of a desk, of any desirable construc tion. The desk top or lid has its front portion, (1, reduced in thickness to receive a supporting-slab, .3, which, when l ving flat upon the reduced portion a, is flush with the top 1 of the upper i'ace ot the lid or top A.

The ends of the snpporting-slab .l are bound by metallie stri ')s which re-enl'orce the support lug-slab, prevent it warping, and

ada' iited to have pivoted to it a movtitliile bar,

D, which is also pivoted to the desk lid or top A, whereby the supportingslab may he raised to the position illustrated in Fig. l. oi the drawings to provide a book-rest. The supportingslab 13 is maintained in this elevated position and rendered capable of adjustinent to any desired inclination by arm E, which engages rack f, formed in side able bar D, intermediate of the ends thereof, and the portion of the movable bar forward ot' the pivotal. pointof the arm E is cut away to permitsaid arm to lie in between the movable bar and the side piece, F, and. be pivotally flush with the edge of the desk.

The side piece, F, one of which is secured to each side of the desk, is constructed of suitable metal, and is cut away intermediate 0t. its ends to form a reccss, 7", to receive the movable bar I) and the arm E.

The rackf is formed bya series'ot. notches made in the side piece, F, at the front end of the recess f, and when the supportingslab B is raised to form a book-rest the arm E engages the rack f and holds the supporting-slab in the desired position.

From the foregoing it will be readily seen that desk tops and lids constructed in accordance with this invention are neat, compact, l and possess great durability and strength, are ca mhleot affordingahook-rest that may be adjusted to any desired angle, and present an even surface when the book-rest is closed and not in. use.
