The present invention is an improvement over acopending application, issued October 10, 1939,

Number 2,175,503 to Miller B. Cook; and relates to drawing tables suitable for nurseries, drawing schools, art schools, studios, drafting rooms and the like, and has for its object, providing one or two adjustable drawing boards per unit hav- 1 ing means for supplying paper therefor from a roll or rolls positioned within the stand. An object of the present invention is to m vide a simple, easily manufactured, lightfand efii'cient stand. 3

A further object of the present invention is to provide a stand which may be equipped with one or two drawing boards, and'wherein when two boards are provided, they may be used simul-..

taneously or alternately without interfering one with the other. f

is to provide a'drawing table having a .roll of paper for each individual board and means whereby thepaper isnot cut free fromthe roll"v until, after it has'been used and a fresh surface moved on the board; and whereby the paper betweenthe board and roll will not interfere with the movement of the board.

Theprincipal object of the present'invention is to provide simple and efficierit means forad justing and locking the, board or desired angle and'height. I

To these and other useful ends, our invention consists of parts, combinations of parts, or their equivalents and mode of operation, as hereinafter described, and claimed and shown in'the accompanying drawingiri which:

Fig. 1 is a front elevation of the preferred form of our improved drawing stand. v

Fig. 2 is an end elevation of the stand as illustrated in Figure 1. 1

Fig. 3 is a top view of one of the drawing boards having thereon a strip of paper.

Fig. 4 is a fragmentary front view of the board and the paper holding means.

Fig. 5 is a fragmentary vertical section of the shelf as illustrated by dotted'lines-in Figure 2.

boards at any Fig.6 is a fragmentary section taken on line. 5- 6 of Figure 3 including fractions of one'of the end members.

Fig. 7 is a detail transverse section of the ad- Figure 6. We provide sheet metal panels ll which are preferablyishaped as shown and spot v f members H. A still further object of the present invention table. It=willbe understood that theupper front board 20 as clearly indicated in Figure 6 having" welded or otherwise sec v to improve :the appearance and strengthen. the stand and form unitary end members.These members. are detachably secured, together by means of a) sheet metal plate 12, and a suitable shelf I3. I we provide holding brackets l4 -l4 which are secured tomembers H as illustrated by ,dotted lines in Figure 1 on which the rolls of paper l5-l 5 may be supported and easilyremoved,

and r p aced preferably by means of round wood barslG.

' ed to members I0;

a It will be understood that the are of said shown-in Figure 2 is optional. We may elect to use but one side of this stand, leaving the other side vertical and close it witha panel which may extend from member l 2 to the bottom edges of ers or shelves in the rear, sides,; or front of the edges of the and. members may be'extended;ver-' tically or at a different angle from that shown. We provide novel meansffor supportingand adjusting the drawing boards -211. The outer .ends are supported by means of assemblylinks We provide roller supports and holdingmeans forthe inner .end. of the board as follows:- A

bracket is provided which is securedltothe Wemay also electto place drawa I aslidably mounted pin 3! This pin is reduced in diameter to thereby form an offset as at 32, the.

reduced end 33 being adapted to rotatably carrya roller 34. Roller 34 is provided with a flange 35. Pin 3| is provided with a spring-36 and. a cotter pin 31 whereby roller 34 is yieldingly held v in the position shown in Figure 6.

We provide a suitable number of registering apertures38 in members In and .Il whereby when r the roller is held in the channel as illustrated,

the protruding end, of member 33 will extend through these apertures. Thus it will be seen thatthe upper end of the board may be securely held many desired position. I

To release the board, all. that is necessary is to press inward on flanges 35 with sufficient pressure to overcome the pressure of sprin'gs33, thus to cause member, 33 to disengage apertures 38 and when this is done, the roller willthen be free to move upward and downward in the channel and and inwardly as at 4|. Members 4! are curved outwardly as at 42. Thus when the paper 39 is drawn over the board, this holding strip is placed 'over the board in the position as shown in Figures 3 and 4. The angle portions 4| will act' to hold the strip snugly against the paper.

We may use two of the holding strips one for the position shown in Figure 3 and another for holding the paper snugly on the inner end of the 53 for the free but snug reception of rod 54.

Opening 53 is slightly extended transversely whereby the flattened end 56 of rod 54m'ay -be removed from the assembly. This, however, is impossible when the. assembly is secured to board 20 and'shelf I 3. Thus the outer end of the board cannot be liftedhigh enough to disengage the rod 54 from tube 4 3. l

"Member 46' is provided with an L ex'tension55 which is of a length which, when in contact with member 44, rod 56will be free to 'move'through aperture 53. f 1 we provide-spring?! adapted to force member 46 into the position shown in Figure? thus to lock the rod or holdit from moving into tube 43 or in otherwords, providing means to supporti'the weight of board 20 and the link assembly, This link assembly is shown practically its shortest adjustment. The lower end of rod 54 is flattened as at 58 so as to provide room for an aperture for the free reception of rod 22. I

When the board 20 is in its lowest position as illustrated on the left side of Figure 2, member 56 will rest against bolt 23. The inner end of board 20 may, as already described, be raised and lowered and if it is desired to change the angle of the board as provided for by link assembly 2|, all that is necessary is to lift on the board because member 46 acts as a one way clutch and when it is desired to lower the outer end of the board, rod 54 may be released by counteracting the pressure of spring 51.

Clearly the board may be conveniently raised or lowered either at its front or rear so as to be held in any-one of the positions shown in Figure 2 or at any intermediate position.

It will be seen that we have provided a drawing stand wherein the drawing board may be moved to any desired position by simply disengaging member- 33 or by simply lifting the outer end of" l the board or by disengaging member 46.

It will be noted that our improved stand is par-- ticularly adapted for use in a nursery or in class rooms because any child can safely move the board to any desired position.

- Clearly many minor detail changes may be made in the various parts of our improved drawing stand withou't departing from the spirit and scope of the present invention as recited in the appended claim. fl-laying thus: shown and ti'on, we claimz' a A drafting table of the class described comprising in combination, 'end members having supportin'g'legs jmeans forlsecuring said end members in spaced relation forming a unitary stand, adrawing board the front and rear of which are separately adjusta bly mounted on the front of said stand as to height, the adjustable mounting for the rear of said board comprising guideways on said end m'embersand projections on the bojard adapt'edto be sli'dably engaged by saidguidewa-ys, said projections having spring actuated means for automatically locking said projections to said guideways, 'means for manuallydisengaging said projections whereby the rear en'd'of said board maybe raised or lowered to any desired position, the adjustable meansfor thefront of said board described our invencomprising two pairs of telescoped links,'the u per I engaged. v
