' OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS DRAWING KIT Application filed June 25,

My invention relates to portable drawing boards and particularly'to an improvement on the construction shown in my, copending applicationSerial N0. 19 1,10? :filed 25,

5 1927. I I l q An object of my invention is to provide a complete and compact drawing kit of anew and improved design, in which I utilize a box or container of relatively rectangular shape and having a'sliding drawer therein adapted to contain various drawing papers and equipment; i

Means are provided on this box for retaining a sheet ofpaper in flat position on the top 1 of the box, as well as to receivea tablet.

In a device of this character the most important requisites are suitable size and weight, with provision for carrying materials and means for insuring comparatively accurate drawings with a T-square and triangles.

In my present improvementI have incorporated means for insuring a more rigid constructionof the box as .well as means for insuring a more uniform and even bearing surface for the T-square.

A further improvement in'my present device relates to the, means for securing the drawer within the box, whereby the box may be inserted and removed with the utmost fa The invention will be more readily understood by reference to the accompanying drawing, in whichy r I Fig. 1 is a planview partly in section of my improved drawing kit; A V Fig. 2 1s atransverse sectional view of my improved device onthe line '22 of Fig. 1; Fig. 3 is a side view showing the aperture in the side wall and the drawer clip therein, 40 and i i Fig. 4 is a sectional View slightly enlarged on the line 4 -4: of Fig. 1. I

By reference to the drawing it Wlll beseen that I have provided a rectangular metal box 4 having top and bottom walls 10,11, respectively, end walls 12, and an indented side wall 131 The edge of the bottom wall 11 is doubled back on itself as at 14: and the edge of the top wall is bent back as at 15. A longitudinal head 16 is formed; in .the'metal of 1925. Serial no. 288,173.

lihood of distortion even after production on 7 perfect dies, either by handling during manufacturing or subsequent use or due to warping by the heat necessary to bake on the enamel used for covering. I have, therefore, "eliminated these sources'of trouble by constructing the area of contact bythe T-square of generallycliannel shape and of comparatively small cross sectional size. stiffness and rigidity without distortion by the heat of subsequent operations and, by pro viding a drawerstop apart fromv the area This insures A I of contact by the T -square,thattrouble is.

The drawerlis intended to receive drawing materials and a pad of paper resting on the top'of the partitions. In withdrawingthe drawer, there is a tendency forthe upper sheets of the pad of paper to catch on the inturned' edge 15 of the top wall and this is obviated by providing the bead 16 in close proximity thereto. I o a As a means for securing the drawer in place and for facilitating its ejection from the box, I provide a finger hole 23 in the wall 13, the hole being located substantially midway between the ends of the box. The fastening clip consists of a spring tongue 24, riveted or welded to the floor of the drawer and having a hooko25 formed near its end terminating in an upstanding arm 26, the arm and hook projecting through the aperture 23 in the back wall of the box. portion 26 is located at substantially the center of the hole 23, and pressure by the finger, on the arm,-serves to rock it sufficiently to elevate thelock 25 out of engagement with the catch 23A located in a plane with the wall 13; continued pressure on the arm will cause the finger to contact the back wall 19 of the drawer, and serve to push the drawer out of the box. Thus the action 'of-unlatching the box serves to also push the drawer-out.

In the top wall of thevbox and located nearthe rear margin thereof are three narrow longitudinal slits 27. These slits are located suificiently close to the rear margin or back the drawer and any dirt or moisture that may drop through the'slits will not drop in the drawer. paper holding bands orclips 28, having at one end a hook 29 adapted to enter a slit and at the other end a rebentresilient portion 30. The clips are composed of spring metal and normally occupy abowed position as indicated in dotted lines in Fig. 2. However, when a sheet of paper or a card are to be held in place on the topof the box, theyare placed in position as indicated in Figs. 2 and 4 the .hook 29 inserted in a slit 27, and the opposite endpushed downward until the end 30 engages beneath the free edge of the top wall. Due tothe construction of the clip 'and' the cooperating parts, the clip will function 'whether the drawer is closed as shown in Fig. 2 or partly open as indicated in dotted lines in Fig. 1. By the provision of three equally spaced slits and elongating the slits to the extent indicated, I am able to hold in place comparatively small cards or large sheets of paper as required. Y Anotherpurpose for the slits is. to provide "for cooperation therewith of tongues or lugs on a metal back for a pad of paper. This is described and claimed in detail in a co-pending application and is not specifically disclosed and claimed'herein. For convenience in handling, the T-square,spring clips, pad of paper and other drawing equipment, all are intended to bereceived within the drawer.

In order to insure atight fit of the drawer when in closed position without too close fitting of the parts, I provide at the back edge ofthe box and fixed to the upper wall a wedge member 31 so placed that the rear end of the drawer is caused to contact the same The end of the.

wall of the box, so that they are not above The slits are intended to receive the drawer-catch The back wall construction notonly provides a rigid. plane surface for contact by the T-square head, but insures the maintenance of this surface notwithstanding relatively rough handling Of'the box and the hammering of the drawer in being returned to its closed position, The pockets provided by the beads serve to trap air and insure somewhat of limited cushioning effect even though the drawer be carelessly returned.

Other modifications and variations may be made in the construction shown, and I do not wish to be limited except as indicated in'the appendedclaims.

I claim:

1. In combination, a metal box and a drawer slidable therein, the top wall ofthe box being adapted for use as a support for drawing paper, a side wall of the box being shaped to provide a narrow continuous plane surface near the said top wall for engagement by the head of a T-square and a relatively indented portion adapted to act as a stop for said drawer.
