Patented Feb. l1, 1947 dialed UNITED s'rArrs 'rarest orifice POCKET DUPLICATOR William F. OGorman, New York, N. Y.
Application August 24, 1943, Serial No. 499,807
My invention relates to a pocket duplicator and its object is to provide a small compact device to be used like a rubber stamp for making impressions from a stencil. Another object is to provide a complete outfit enclosed in a small case for making stencils and using them.
These and other objects of the invention will appear in the following specification in which I will describe a duplicatcrv outfit which is made according to and embodies the present invention, the novel features of which will be set forth in the appended claims.
Referring to the drawing:
Figure l is a perspective view of what I now consider a preferred form of my duplicator. In this View the parts are unfolded and no stencil sheet is shown.
Fig. 2 is a perspective View of a stencil holder with a platen and a stencil sheet therein.
Fig. 3 is a transverse section of the parts shown in Fig. 2.
Fig. 4 is a perspective View of the stencil holder and a stencil sheet therein without a platen..
Fig. 5 is a transverse section of the parts shown in Fig. 4.
Fig. 6 is a transverse section of the parts shown in Fig. 1 with a stencil and with the parts folded `together and ready for use.
Fig. '7 is a perspective View of the parts shown in Fig. e and of a protective cover therefor.
Fig. 8 is a perspective View of a plurality of stencil sheets surrounded by a wrapper.
' Figs. 9 and 10 are perspective views respectively of a Vstylus and .ink spreader which form parts of the outfit.
Fig. 1l is an actual full size perspective View of a case with all parts of the outfit therein.
2S designates a rectangular block of Wood or other suitable material on one side of which, designated by 2 l an ink pad 22 is attached. The ink pad is narrower and shorter than the side 2 of the bloei-.r and is centrally located therein.
it is a cover sheet of thin fibre board of a width equal to the length of the block. This is creased transversely to form parallel fold lines which subdivide the cover sheet into different sections. rlhe rst of these sections forms a tab 3l which is arranged to extend away from the side 23 of the block, as shown in 6,` or folded down to a position parallel with the side of v the block when the device is not in use, as shown in Fig. l. The next section of the cover sheet, designated by extends from the fold line between it and the tab 3l, which is spaced from the edges 22 of the block as shown at 33, to the opposite edge 25 and is axed to the block by suit able means, such as staples te.
Next is a narrow section 35, the width of which is approximately the same as the thickness of the block and is adapted to cover its edge 25. The'section designated by 36 Vcorresponds to the size and shape of the side 2l of the block to which the ink pad is affixed. A portion of this section, which corresponds to the size and shape of the ink pad is cut away as shown at 36A.
3l and 38 are narrow sections, the rst of which is adapted to overlie the edge 24 of the block and the second is of a width which corresponds tothe distance of the fold line between the tab 3l and the edge 24 of thel block. The section 32 is a tab which corresponds in size and shape to the tab 3 i.
lil is a stencil sheet holder which comprises a sheet of stiff paper or the like, transversely folded on a median line ll to form overlapping layers 42, d3, the Width of whichicorresponds to the length of the block 2li. An opening M of the size and shape of the ink pad 22 is cut out of the upper layer d2. At the ends of this opening parallel lines i5, l5 are printed which are spaced apart the distance between the lines printed by a standard typewriter.
A stencil sheet llS of a length equal to the length of the block 2t! and a Width approximately equal to the width of the block and two of its edges 2d, 25 is placed between the layers ft2, it with one of its edges abutting the fold line il between them. ll is a platen with a slightly roughened surface placedunder the stencil sheet.
A convenient way of making a stencil is to inn scribe within the opening lli, the desired matter to be duplicated by a stylus such as that shown at in Fig. 9.
Another Way of making a stencil is to put a stencil sheet it in a stencil sheet holder il@ without the platen, as shown in Figs. 4 and 5, place the stencil sheet holder on the platen of a type- Writer and print the desired matter with the typewriter, guided by the lines d5.
After the stencil sheetI li has been prepared, it is removed from the stencil holder and placed on the block 20 over the previously inked pad 22 with its paper side against the pad and overlying the top 2l of the block and its opposite edges 24 and 25. The sheet 3Q is then folded around the block 2e and its section 35 will hold the stencil sheet t in position. The tabs 3l and 39 when in raised overlapping position, as shown in Fig. 6, may be grasped between the fingers and the insignia inscribed on the stencil sheet i8 stamped on a piece of paper or other desired surface.
When not in use the tabs 3| and 39 are folded down into parallelism with the surface 2| of the block and the device slipped into a protective cover 6B (Fig. 7). The side 6I of this cover is raised as shown, to form a space between the inner side thereof and the ink pad 22 and the overlying stencil sheet. The Side 6I of the cover and its opposite side G2 are tapered at one end so that the outer corners of the inserted dupli.
cator are exposed to facilitate its insertion and removal. The rear end of the protective cover (not shown) is closed.
Although in the small size shown the opening 4H is only three quarters of an inch wide, this is suicient to receive three lines of type- Writing.
A bundle of stencil sheets is shown in Figs. 8 and 11 surrounded by a wrapper A9. In Figl 11, 80 designates a case with folding aps 8l, 82 and 83 at one end with the various parts of the outt which have been described therein, together with a bottle oi ink` SS and ink dauber di. A perspective View of the dauber appears in Fig. 10.
One of the features of this invention is that it provides an arrangement which enables the use of a very small stencil which is easily manipulated and is extremely compact so that the duplicator and all ofthe parts of the outfit may be enclosed in a pocket sized case. I realize that modifications may be made Within the spirit and` scope of kthe invention and intend no limitations other than those imposed by the appended claims.
What I claim is: f
l. A duplicator comprising a flat rigid block, an ink pad aixed to and projecting from one side of the block and being of smaller Vtransverse dimensions than those of said side Vof the block, a stencil sheet arranged to lie over the pad and opposite edges of the block, and a cover sheet arranged to be folded around the block and over the parts of the stencil sheet on the edges of the block, the section of the cover sheet over the side of the block having the pad thereon corresponding in size and shape to those of said sides of the block and being constructed with an opening therein of smaller dimensions .than those of said side of the block, the ends of said cover sheet forming overlapping finger tabs.
2. A duplicator comprising a flat rigid block, an ink pad affixed to and projecting from one side of the block and being of smaller transverse dimensions than those of said side of the block, a stencil sheet arranged to lie over the pad and opposite edges of the block, anda cover sheet arranged to be folded around the block and over the parts of the stencil sheet on the edges of the block, the section of the cover sheet over the side oi the block having the pad thereon corresponding in `size and shape to those of said sides of the block and being constructed with an opening therein of smaller dimensions than those of said side of the block, the ends of said cover sheet forming overlapping finger tabs projecting from the block and arranged to be folded down onto the block.
