The invention relates to stencils and .inking devices therefor and is particularly adapted to be embodied in stencils of the type commonly employed in mimeographing machines.
In accordance with the invention, I provide an improved stencil comprising in combination theretion of the ink or color, which solution will in,` turn pass by capillarity through the stencil and to the impression surface thereof. This invention has other advantages which` will become apparent as the following. detailed descripton progresses, reference being had to the accompanying drawing which is a fragmentary section taken. through a stencil, improved means for inking the stencil and means for moistening?4 the inking means.
1933 Patent No. 2,012,526, August 27, 1935.
The stencil 20 designates generally av stencil of `the conventional type. The stencil 20 preferably comprises a sheet of paper 2| provided with the usual coating 22 which may be a lacquer having a cellulose base. The paper backing may be suitably formed of any of the known suitable porous papers that will permit the passage of liquids therethrough by capillarity and is for example preferably yoshino paper. The reference character 25 designates an inking device or color carrier which comprises a sheet of paper |217, similar to the paper backing 2|. paper |2b is provided with a coating Mb which comprises a dye, color or ink preferably soluble in water, although other dyes and inks as for example the water insoluble dyes or inks may be used and subjected to suitable solvents therebind the dye or pigment to the paper and will` f not prevent solution of the dye when the solvent is brought into contact therewith. As an example of a suitable vehicle for use with water as the solvent, gum arabic and glycerine may be used. In the drawing, the lnkimz devine 25 is shown One surface of the interposed between the stencil 20 and a moisten- .ing means Ib which may be, for example, preferablyr a he'ctograplrbandl comprising apaperV backing |517 having a coating |617 of gelatin. The moistening means I Ib may comprisev a layer of cloth, felt, gelatinized material or in lfact any other `material capable of 'storing and delivering a supply of solvent or capable of transmittingthe f solvent from a reservoir to the stencil.` I-Iowever,l
in this instance I have shown a duplicating band of the type employed in hectographmachmes.
- The data to-'be duplicated are cut into the coating 22 as indicated at '|8b.
When the inking device 25 is to be employed in a duplicating operation, the stencil 20 is placed upon'the coating |4b and the inking device 25 is placed upon. the gelatin coating |6b in the manner illustrated in the drawing, the gelatin coating 6b having first been thoroughly moistened. `Water from the gelatin passes upwardly by capillarityv through the paper |21) and dissolves the ink or inkor dye. 'Ihis solution then Lpasses by 'capilcated are placed upon the coatingy 22 and sufiiydye in the coating |4bto form a solution of the ,v
cient pressure is applied to the sheets so that the.
datalwill be duplicated thereon. This application is a division of my co-pendingv application, Serial No. 663,581, filed March 30,`
l I`claim: v l
1. In combination with a stencil, an inking ing an yinking substance applied to a surface of lao devicev comprising a paper, and a coating includthe paper, said inking substance being adapted to device carrying a dry dye or ink in back thereof f and moistening means incontact with said inking device, said moistening means containing a solvent adapted to pass by capillarity through ther inkingdevice and stencil and carry with it the ink contained in the inking device to deposit it at the impression surface of the stencil.
3. A composite structure for ruse in a duplicating process comprising :a stencil having an impression surface and a porous backing, asolvent storage meanscapable of transmitting the solvent yto the stencil and' any intermediate 'inlndee comprising a porous backing in contact with said" N means and a coating of a color on said backing in contact fwith'the stencil backing whereby the so1-.
vent will pass by capillarity through the inking device to form a solution of-the color thereupon and the solution of color willpass by capillarity through thestencil toythe impression 'surface'.
