,6'Claims.

The present inventionrrelates to drawing: tables suitable for nurseries, -;drawing schools, art schools, .-studios, and thelike, and has for its object providing one or two adjustable drawing boards thereon having means for-supplying paper therefor from a roll or rolls positioned-within: the table.

An object of the present invention. is tog-provide a simple, easily-manufactured, light, and-efiicient table for the purpose.

A further object of theqpresent. invention is to provide a table whichmaybeequippedwith one or two drawing boards, .and-whereinwhen two boards. are. provided they maybe used simultaneously or alternately withoutin-terfering one with the other.

A fur her object of the present invention isto provide a drawing table having a roll of paper for each individual board and means wherebythe paper is not out free fromtheroll untilafterit has been used and a fresh surfacemoved .on the board; and whereby the paper. between the-board and roll will not interfere-withthe.movement of the. board.

Another. object of my invention is to ;provide simple means for adjustingandlocking the board at any desired angleiromhorizontalto vertical.

A further object of the present. invention. is to provide a table for nursery use whereby suitable papers, having sketches, may be placed .under the semi-transparent :paper from the roll {for tracing purposes; or whereby, the outline of animal forms and the like mayabeplacedon the rolls for juvenile tracing, copying, ,or;coloring purposes.

To theseand other useful ends myinvention consists of parts, combinationsthereofor.their equivalents andmode of operation ashereinafter described, and claimed and shownlin the accompanying drawings in which:

Fig, 1 is a side elevation of myimproved drawing table.

Fig. 2is afront elevation ofthedevicerviewed from the left of Figure 1.

Fig. 3 is a top view of the drawing board after being detached from the table but retaining the paper from the roll and having thereunder :a typical sketch from which to trace orcolor.

Fig. 4 is a front view ofithe board as; shown in Figure 3.

Fig. 5 is a detail of one of the holding and guiding devices for the upper end-oi the board taken on line 5-5 of Figure 1.

As thus illustrated,.my inventionconsistsaof two end members lll|0--each ,formedpreierably from a U shaped channel 5. I provide a sheet metal panel H which is preferably shaped as shown and spot welded or otherwise secured to members i thus to improve theappearance and strengthen the table .35

as illustrated in Figure secured to members II as illustrated by dotted r10 lines in Figure 1 on which the rolls of paper I 5-|5 may be supported and easily removed and replaced.

It will be understood that the form of'table shown in Figure 1 is optional. but one side of this table, leavingthe other side vertical or as shown and close it with a panel which extends from member" to the bottom edges of members I l. I may also elect to place drawers or shelves in the of the table.

I provide novel means for supporting and adjusting the drawing boards iii-42H. The lower ends .are supported by means of linksj2 l'-2 I; these links are preferably pivoted at their bottom ends to the end members in any suitable manner by means of bolts as at;22 22 and at their upper ends to the table as at 23-23.

I provide roller supports and holding means for the upper end of the board as follows: Brackets 30-30 are provided which are secured to the board 20 as clearlyindicated in Figure 5 each having slidably mounted pins Iii-3i. These pins are reduced in diameter to thereby form oifsets as at 32, the reduced end 33-being adapted to rotatably carry the rollers 34-34. Rollers 34 are provided with flanges 35. Pin 3! is provided with a spring 35 and a cotter pin 3'! whereby the roller 34 is yieldably held in the position shown in Figure 5.

I provide a suitable number of orifices 33 whereby when the roller is held in the channel as illustrated, the protruding end of member 33 will project through these orifices; thus it will be seen that the upper end of the board may be securely held in any desired position.

To. release the board all that is necessary is to press inward against fiangesi35 with sufficient pressure toovercome the pressure of springs 35, thus to cause members 33 to disengage orifices 38 and when this is done the rollers will then be free to move upward and downward in the channel and the board may thusbe moved and locked to any desired position.

xThelowest orifices arepositioned.whereby the rear, sides, or front.

I may elect to use .15

board may be placed and held in a horizontal position as illustrated on the left in Figure 1. The highest preferable position of the board is illustrated on the right of Figure 1 and an intermediate position is illustrated by dotted lines on the left of Figure 1.

I provide preferably suitable paper holding strips 40-40. Bolts 4| and thumb nuts 42 are also provided. The bolts pass through orifices in strips 40; thus the paper may be positioned and held under these strips. By referring to Figure 1 it will be noted that the paper is threaded under the inner strip and extends over the board and is threaded under the outer strip, the loose end protruding as at 43.

After the paper on the board has been used, the thumb nuts are loosened and the paper pulled so a fresh surface is supplied to the board and made fast as already explained. The used portion of the paper is torn off as at 43.

Thus it will be seen that the board may be easily secured in any desired position, and that the used paper may be conveniently replaced from a continuous supply. It will also be noted that when the board is moved from one position to the other the paper roll will accommodate this movement as illustrated by dotted lines in Figure 1.

It will be understood that the connections between the two end members are preferably detachable, thus the end members may be laid flat and packed with the boards and other parts in a neat shipping container.

Clearly, applicants invention is particularly suited for juvenile use as well as for studios, class rooms, etc. In Figure. 3, I illustrate by dotted lines a sheet of paper, having thereon, the outline of a rabbit. Such sheets may be supplied to the trade and they may be used as many times as desired. I have also contemplated printing various lines and figures on the roll of paper.

It will be understood that various minor changes may be made in the details shown and described without departing from the spirit and scope of the invention as recited in the appended claims.

Having thus shown and described my invention I claim:
