IMPROVED FOLDING DESK.

TO ALL WHOM IT MAY CONCERN: o

Be itknown that I, THEODORE W. KREITZ, of Quincy, in the county of Adams, and State of Illinois, have invented a certain new and improved Portable Folding Desk; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, rcference'being had to the accompanying drawings, of whicl1- l Figure 1 is a perspective view of the desk elevated for use, and

.Figure 2 the same when'closed or folded for transportation.

In the drawings, a, iig. 1, is a board, serving as a foundation, to which is jointed, at its front edge by hinges, the frame IJ. To the back edge of this frame is hinged another frame, c, similar in all respects to the" lfra-me b, and to its front edge is hinged in like manner the board or panel d, which serves as the platform orV table surface of the desk, and is furnished with a raised strip at its front edge to prevent a book from slipping down. To each of' the frames Zz and c and the platform d, about the middle of their under sides, are hinged the frames or props e, the ends of which catch into the notches f out respectively on the upper sid-es of theframes b and c and the panel a. These props serve to sustain and adjust the several parts in a suitable position and elevation for the purposes required when in use, and when the instrument is folded together they lic lat in recesses prepared for them in theseveral pieces to which they are attached.

The instrument as shown in the drawings is designed to sit on a table, box, barrel, or anything handy which may serve to support it within a certain range of elevation. But by increasing the dimensions ortho number of i'rames similar to I and c, the desk may be `adapted to sit on the ground without other support. A modification of vitrma-y also 'be applied to the arm oila chair to enable the sitterto read-and writegvith ease and l comfort. Inksta'nds, pen-holders, or other conveniences for writing, may be attached in suitable' positions to the platform d.

What I claim as my invention, and desire to secure by Letters Patent, is- A portable folding desk, consisting of a frame a, panels c, and top d, jointed or hinged to each other,

which, when elevated for use, are supported at the desired elevation bythe props or pawls c and the notch es j',

constructed substantially as and for the purposes described.
