Patented ov. 7, 1 950 POCKET SKETCHING SET John E. Lindberg, Jr., Redwood! City, Calif.

Application January 4, 1947, Serial No. '720,252

This invention relates to an improved pocket sketching set and note pad.

One object of this invention is to provide a sketching set which can be used to carry sketching paper or cards safely in a pocket and be also available for use as a support for sketching.

Another object of this invention is to provide a transparent envelope for carrying sketching materials, which will besuitable as a small drawing-board for sketching, having means to hold paper or cards on its top surface.

A further object of this invention is to provide a sketching set which will frictionally retain paper inside an envelope, will hold paper on its outside for sketching, and which will carry measuring scales, and cut-out designs of convenient figures for aiding in sketching; all asV a unit suitable for carrying around in a pocket without danger of breaking or bending or dirtying the paper.

Another object of the invention is to provide a sketching set suitable for quantity manufacture from transparent, fairly stiff, foldable, and flexible plastic.

Other objects and advantages of the invention will appear from the following description.

In the drawings:

Fig. 1 is a View in perspective of a device embodying the invention; Y

Fig. 2 is a top view looking down at the open end of the envelope;

Fig. 3 is a side view in section taken on the line III- III of Fig. 2; and

Fig. 4 is a plan view of the separator.

The envelope I is preferably made from a sheet of plastic folded'along the edge II, the surface I2 being left fiat and the opposite surface I3 being bowed in at the center, as shown in Figs. 2 and 3. The envelope is completed by folding the side flap I4 and the bottom flap I5 over so that the edge I6 of the flap I4 and the edge I'I of flap I5 rest on top of the flat surface I2. Preferably the corners of these two iiaps I 4 and I5 are cut out along a curve at the portions 20, 2 I, 22, and 23.

As thus constructed, the envelope II) will retain paper or cards, etc., even if held upside down, for the pressure exerted by the bowed-in surface I3 toward the flat surface I2 is sufficient to hold them; at the same time being flexible and elastic, it readily yields to hold more paper or cards. To make it easy to place cards in the envelope, the surface I3 is flared somewhat at its top edge 24, and cut-out portions of thumbholes 25 and 26 are provided along the open edge of each of the surfaces I2 and I3.

The flaps I4 and I5 provide a means of yield# ingly holding paper and sketching aids on top of the surface I2, which can thus be used. as .a writing or sketching surface. The edges I6 and I1 will hold the paper, etc., frictionally, and the material is sufiiciently elastic so that it willi ac*- commodate varying degrees of thickness.'

The sheet 21 is made narrow enough to t into the envelope IIJ, and long enough to project therefrom, so that it can be a .convenientseparator between papers or cards inside. It ispreferably madeV of transparent plastic, is preferably removable from the envelope I0, and bearsonV its surface various aids Yto sketching, such vas the scales 30 and 3I along the converging edges 32 and 33, and the various cut-out stencil designs similar to those illustrated. Since the flaps I4 and ,I5 have rounded corners, the separator can slide along under one of them and over the other, so that it can be held `on the sketching surface I2 in many positions.

It is contemplated that the set will have uses other than for sketching, such as for notes and business cards, and that the envelope will have uses with or without the separator. Changes may be made in size-as, for example, to make it large, so that it will be almost portfolio size, or smaller, as, say, wallet size. Changes may also be made in design, material, shape, and arrangement which will not depart from the invention as claimed.

I claim:

1. A holder for paper and similar material, comprising a sheet of relatively stiff but still flexible material folded' to provide van envelope open along one edge and also folded to provide relatively stiff flaps adaptedv to overlap one face of said envelope and to remain closed .over it along two other mutually perpendicular edges for frictionally holding paper and similar material against said outside face between said flaps and said face. Y

2. A holder for paper and similar material, comprising a vsingle sheet of material which is relatively stiff and still elastic and flexible, folded to provide an envelope open along one edge, having one of its faces flat, two of the mutually perpendicular closed edges being folded over onto said flat face to provide holding flaps for flat objects on said at face, and having its other face bowed in at the center to provide sufficient pressure to frictionally hold paper and similar material inside said envelope without deformation and also sufficient pressure between said flat face and said two mutually-perpendicular foldedprovide a holding means for said ilat face, the corner where said folded-over edges intersect being out away, so that the edge of a piece of' paper may be frictionally retained on the outside of said holder by either of saidedgesfand may slide along the full length or width of saidholder.` 4. A holder for paper and similar materialmade from a single sheet of transparent plastic folded tonprovide yany envelope, open along one edgeghaving one of it's faces bowed in at the center toprovide suflicient pressure to holdfrictionally and resliently without deformation p'a'per and similar material inside said envelope, and

havingiits. other faceV flat,` two of the closed edges being folded over permanently to provide a holding means for said at face, said flat face being urged by the pressure of saidbowed-in face into contact with saidedges, except when a flat object is forcedtherebetween and held there by said pressure.

5f.v A pocket sketching set including a single sheet-of transparent vplastic folded to provide-an envelope open at one edge, and having cut-out thunibeliolesalongsaid edge, the two `mutually perpendicular edges other than said open edge and theiedge wherevthefoldfismade, being folded around to close said envelopeand provide holding inea/nsV on one yof the-outside faces thereof, the corners of said folded over edges being cut away in'a ciirve, Asa-idfac'ebeing nat, the opposite face of! sai`d envelope being bowed in at the center tward-said'ilat face, and a removable separator of' transparent plastic/slightly longer than said envelope-but narrow enough to fit within it', having thereon guiding edges and cut-out portions of various shapes of use in sketching, adapted to be aligned and retained slidably by either foldedover edge.

6. A holder for sketching material comprising an envelope of relatively stiif but still flexible material open at one edge and having two of its mutually perpendicular edges folded over the flat outer surface of one side of said envelope so as to frictionally retain paper thereon and to align and retain slidably a sketching aid along the two mutually perpendicular directions, the corners of said folded edges being cut away, so that an edge of said aid may slide along the full length or width of said envelope.

7. A pocket sketching set including a single sheet of a-relatively stiil but still flexible material folded vto provide an envelope open at one edge, the-tivo mutually perpendicular edges other than said open edge and the edge where the fold is made, being folded around to'close said-envelope and provide holding means on one of theoutside faces thereof, the intersecting corner'v of said folded over edges being cut away, said face being flat and the'opposite face of said envelope/being bowedin at the center toward said flat face; and a removable separator sheet slightly longer than said" envelope, but narrow eno-ugh to fit within it,'ha"ving thereon guidingv edges and cut-outportion's of vvarious shapes Aof use in sketching, adapted to be aligned and retained slidably -by eitherfolded-over edge.
