To @ZZ whom t may concern.'

Be it known that I, TJARK J. HOUTMAN, a citizen of the United States, residing at New York, borough of Manhattan, in the county and State of New York, have invented neW and useful Improvements in Desk-Slides, of which the following isa specification.

`By means of this invention a desk-slide can be utilized for the preserving of memoranda or temporary notes and the like Without the utility of the slide as an ordinary support for writing or the like being interfered with.

The invention is set forth in the following specification and claims and illustrated in the annexed drawings, in which- Figure l is a perspective view of the slide. Fig. 2 is a plan view of the slide. Fig. 3 is a section along ce, Fig. 2.

The slide is shown comprising the side pieces or rails l and 2 and the panel or bottom piece 3. This bottom piece does not rise as high as the rails, so as to leave a depression or seat for a slate or tablet 4 and a glass plate 5, which latter can be made to retain an underlying calendar, timetable, or like object for ready reference. The tablet or slate 4 and transparent retaining-surface 5 till up the seat or depression and come iiush With the top or supporting face of the slide or its parts l and 2. The seat or recess has oppositelybeveled edges, or rather the inner ends of the rails l are undercut or beveled, as seen at 6 and 7. The slate 4 has its opposite ends beveled, and its sides are vertical, andthe plate 5 is likewise formed. One bevel of slate 4 being slipped or engaged to bevel 6 and a bevel of plate 5 held by bevel 7, a1ail8, having opposite bevel or undercut edges, is placed between the adjacent bevel ends of

parts

4 and 5, which face or lie toward one another, so as to overhang such parts, and thus securely hold the panels in the depression in the slide. The rail 8 being secured by fastenings 9, the slate 4 and plate 5 are secured in place by the ac tion of bevels C, 7, and 8. At the same time it is only necessary to remove the fasteningstrip 8, when slate 4 and plate 5 can be removed, asA for replacing a broken slate or changing the matter held under or by plate 5.

By the arrangement shown, wherein the opposite beveled edges of the rail 8 act upon the adjacent beveled edges of the tablet and plate,

respectively, it will seen that la clamping and spreading action is had' which tends to force the outer beveled edges of the said tab-A let and plate under` the inclined undercut ends of the depression, and thus hold the parts securely in place against endwise or other movement.

The strip 8 is shown held in place by screws or bolts 9, Whose heads and nuts, being flush at top and bottom of the slide, do not hinder the latter moving in and out of place.

The tops of rails l and 2 of slate or tablet 4 and plate 5, with rail 8 and fastenings 9, being all flush or on the same level, a sheet cau be laid on the slide and be supported for writing as on an ordinary slide. The ordinary use of the slide is thus not interfered with.

The tablet 4 is preferably made of a white slab, so as to be Written on with an ordinary pencil or, perhaps, with ink, so as to make memoranda or figures, which can be erased or Washed away when no longer needed.

The slide and rail 8 can of course be made of suitable material-wood, metal, or a combination of materials, as called for.

While the slide is in the desk the tablet 4 is protected or concealed; but the slide need merely be pulled out to expose the tablet for writing.

What l claim as new, and desire to secure by Letters Patent, is

l. A deskslide having a depression in its top surface, one wall forming an end of'said depression being undercut on an incline and the side Walls being vertical, a removable and replaceable tablet or plate seated in said depression so that the upper surface thereof will be flush with the top of the slide, and having its opposite ends beveled, one of said beveled ends fitting under the said undercut end Wall of the depression, a removable transverse rail seated. in the depression and lying ilush with the top of the tablet and slide, one side of said rail being undercut on an incline to overhang the adjacent beveled end of the tablet or plate when the parts are in position,

and means for detachably securing the rail to the slide, substantially as described.

2. A `desk provided with a horizontal slide moving in a recess therein and having .a depression in its top surface, the outer end walls forming said depression being undercut on' IOO an incline and the side Walls being vertical, a removable and replaceable writing-tablet and a transparent plate seated in said depression in the slide so that the upper surfaces thereof Will lie flush with the upper face of the slide and each having;` beveled opposite ends and vertical side Walls, the outer beveled ends of the tablet and plate, respectively fitting under the said inclined undercut end Walls of the depression, a removable transverse rail extending between and bearing upon the adjacent beveled ends of the said tablet and plate and having its opposite sides undercut on an incline to overhang and abut TJARK J.
