Application filed July 6,

The present invention relates to a table and lap drawing and reading stand and the f prime object of theinvention resides in the provision of a drawing board and a reading and writing stand which can be used clamped onto a table or can be mounted onto a small board and used as a lap stand 'andreading and writing board.

Another very important object of the in 1Q vention resides in the provision of an appa-' ratus of this nature which is adjustable for both the height and angle and can be used on any table,.square, rectangular, round or oval, and used by its owner with a regular height chair or raised stool. or standing.

A still further very important object of the invention resides in the provision of an apparatus of this nature which is simple in its construction, inexpensive to manufacture,

strong and durable, thoroughly effioent and reliable in use and operation, easy to adjust, and otherwise well adapted to the purpose for which it is designed. 1

l/Vith the above and numerous other objects in view, as will appear as the description proceeds, the invention resides in certain novel features of construction and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing: j Figure 1 is a side elevation of the apparatus embodying the features of my invention. Figure 2 is a rear elevation thereof. Figure 3 is a perspective view of the board. Figure 4 is a perspective view of one of the clamping irons. I v

Figure 5 is a perspective view of the other clamping iron, and

Figure'G is a perspectiveview'of the stand member.

Referring to the drawing in detail, it will be seen that the letter A denotes a stand which comprises a substantially U-shaped construction, having 'a flat rectangular base 5, with upstanding ends 6, provided with openings 7 adjacent their centers and openings 8 adjacent their ends. A rod 9 extendsthrough the openings 7 and through openings 10,and 11 in elongated bars 12 and 14 5 respectively. The bar 14 has a right'angled 1929. Serial 1%. 376,419.

extension 15' at its lower end to be disposed I under a table 16, board, or any other like supporting structure, and is formed with an opening 17, through which extendsa bolt 18,- the head of which engages under the table 1'6, therebeing a spring 19 disposed about the bolt'impinging' against the head and the extension 15. V

'A nut 20 is engaged on'the bolt to' limit the upward movement thereof. vOn'the bar "12 at its lower end is an oblique. extension 21, having an opening 22 therein, through which is threaded a bolt 24 having aswivel ball and socket joint connection 25, with a V-shaped' member 26, for engaging the edge of the table 16 or the like, and thus by adjusting the bolt 24 and sliding the bars 1 1 and 12 on the rod 9, the stand A. may be mounted on any shaped table or like supporting structure.

A pair of bolts 28 are' engaged in the open ingsS of each side 6 and extend through the slotsof the, elongated. slotted bars 29. which have one end portion straight and the other end portions arouate. 1 i Inverted U-shaped members 80and 31 are mounted on the under surface of the-board 32', the former intermediate the ends thereof and the latter at the upper end thereof. The sides I of the member are slotted or notchedias at 33, to receive bolts 24, while-the sides ofthe member 31 are apertured as at 35', to receive bolts 36, ofarms 87, whichare provided with elongated slots 38,'to,receive bolts 39: which also extend into the slots of the bars 29. Ob-

viously'by loosening the bolts128, 39 andBfi, practically any adjustment of the board 321 desired may be obtained'so as t to place i t at a desired angleto'the supportingstructure 16 or in parallelismtherewithasimay be de-' sired. Q

/ It is thought and advantages 01? this invention will now be quite apparent to those skilled inv thisart, without a more detailed description thereof. The present embodiment of the inventionthat the constructiom'utility has been disclosed in considerable detail merev 1y for the purposes of eXemplification, since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It Will beapparent that changes in the details of construction and in the combination 5 and arrangement of parts may be resorted to,

Without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

lVhatis claimed is:

1; In an apparatus of the class described, U-sha-ped supporting stand, a rod extending through the sides thereof, means for clamping the rodto a table orthe like, a board, and means for adjustably mounting the board on the stand. s

2. In an apparatus of the class described, a

U-shaped supporting stand, a rod extending .throughthe sides thereof, means for clamping the rod to a table or the like, a board, and

20, means for adjustably mounting the board on the stand, said means for clamping the rod on atable or the like comprising a pair of depending bars slidablymounted thereon, one of thebars having an inturned extension at rightangles'thereto, a bolt slidalole through i the extension, spring means for pressing the boltoperatively to engagethe under surface of thetable or the like, the other bar having an oblique extension With a bolt threadedly' engaged therein, anangular member, and a ball and socket connection between the last mentioned bolt and the angular member so I that the angularme'm'ber may be'engaged with the edge ofthe table or the like.

3. Inan apparatus of the class described, a

" U-shapedlsupporting stand, a rod extending through the sides thereof, meansfor clamping the] rod to a table or the like, a board, and

7 means for adjustably mounting the board on the stand, said adjustable means comprising a pair of elongated slotted bars having straight portions and curved portions, bolts engaged in the slots thereof and in thesides of the stand, means for engaging the board with thebars.

' 4. In an apparatus of the class described, a U-shaped supporting stand, a rod extending through the sides thereof, means for clamping v the rodto a table or the like, a board, and 50, means for adjustably mounting the board on the stand, said adjust-able meanscomprising a pair of elongated slotted bars having straight portions and curved portions, bolts engaged in the slots thereof and in the sides of the stand, a pair of inverted U-shaped members on the bottom of the board, bolts 7 connecting one of said members with the bars, slotted arms connected With the other of said members and said slotted bars. 7 V In testimony whereof I have afiixed my signature. s
