Definitions

  • the present invention relates to stencils made of coated Yoshino paper, orlike loose flbred fabric, and its main object is the rendering of the legend or design cut or indented in the coating of y such stencil more easily read, both before and after the stencil has been inked.
  • the invention comprises a stencil blank or sheet having a iilm of coloring matter of the proper character to render it pervious to ink after having been crushed by type blows and/or removable Wholly or in part by such blows on that side which I will call its back, and the stencil formed therefrom by indenting or cutting a legend or design in the coating on the face of the loose iibred fabric which forms the base of such stencil sheet.
  • the present invention is an improvement on, or modification of, that described and claimed in Patent No. 1,645,593 granted October 18, 1927, to Erwin A. Geiger, in that a coloring material of the character there described is preferably used.
  • Both inventions are primarily designed for use on stencil sheets or blanks made of Yoshino paper coated with a coagulated film of a composition having a gelatine base, such as haybeen generally used in the paper stencil art for 20 years.
  • the coating of such stencil sheets or blanks is generally done by drawing the sheet of Yoshino paper across the surface of a bath of the coating liquid. As aresult the major portion of the coating material is left on the under surface of the paper, while only a minor portion soaks into the paper and through it to the other surface. After the coating material has been allowed to set on the Yoshino base it has a glassy surface and the Icoated sheet is slightly transparent, having an approximately white color.
  • the stencil from ⁇ such a sheet or blank it is placed in a typewriter with the more thickly coated surface presented to the action of the type, or if the stencil is made by a stylus the marking by the stylus is done on the same surface, which, for brevitys sake, I will call the front of the stencil sheet, the more thinly coated surface being called the back.
  • Stencils made in the above described manner in the shape of small cards are, and have been, for 20 years used extensively in addressing machines, and in such use particulary it is important that the legend cut in the stencil in thisrnanner shall be legible to the user both while being cut on the typewriting machine and afterwards during all periods of use so that he can tell the name and address that will be printed therefrom in the addressing machine, and make any necessary corrections before the stencil goes into use.
  • Such stencils as heretofore have been made out of the nearly white coated paper are slightly legible because the bottom surfaces of the indentations formed by the type 'are white, or at least more nearly white than are the remaining, unbroken or uncrushed surface portions of the sheet.
  • the Geiger patent above mentioned marked a step in advance by proposing to use an alcohol dye, or one in a similar non-acid vehicle which would not permeate the entire coating of the paper, but would only mix with the surface portions thereof; and by also proposing to further limit the dyed zone by mixing such dye with shellac which would adhere to the surface, rather than permeate far into the interior of the coating layer.
  • stencils made according to the present invention are more legible after being inked than are stencils not so made.
  • FIG. 1 is a perspective view of the stencil blank looking at the back thereof.
  • Fig. 2 is a cross section on line 2-2 of Fig. 1.
  • Fig. 3 is an enlarged detail cross section of the stencil sheet with certain of the dimensions exaggerated for clearness. o
  • Fig. 4 is a front view of the stencil, to the back of which a iilm of red dye has been applied, and the right hand portion of the face of which has been inked, and
  • Fig. 5 is a face view of the backing panel removed.
  • 1 indicates the frame of the stencil card generally which in the form shown is composed of a back frame section 6a and a front frame section 6 between which the intermediate sheet of paper 5 has been cemented or pasted.
  • '7 represents a stencil sheet preferably of coated Yoshino paper, the edges of which have been pasted to the sheet 5.
  • a panel 9 has been partly cut out from sheet 5, being outlined by lines of perforations or slits indicated at 2, 2, and having one end free to form a tab 3 by which it may be readily torn off, the above described construction being that shown and described in my said Patent No. 1,909,913 above mentioned.
  • This latter feature may usually be omitted, as such backing panel, being hygroscopic while the coated sheet is non-hygroscopic, the former is liable to absorb moisture, swell and buckle so as to form blisters.
  • the stencil sheet 7 is composed of the sheet of Yoshino or other loose bred fabric 4, which has been coated with a coagulated, slightly transparent iilm l0 by drawing the paper across the surface of a bath of such material in liquid form, with the result that a major portion of the coating is deposited on the under side of the paper sheet 4, a minor portion soaking into the paper and through to the other side to form a thin film on said other side.
  • 8 represents the lm of coloring material applied to the back of the coated sheet by drawing the sheet across the surface of a bath of the coloring material with the back of the sheet in contact with the surface of the bath or by any other proper method such as painting or rolling it on.
  • Fig. 4 at the right hand I have indicated at 13 an area of the front of the stencil card which has been inked.
  • the lm of ink usually of a blue black tint is so thin on the smooth surface of the coated paper that it does not entirely blank out the red or other contrasting color beneath on the back of the stencil, but the effect on the eye is that of a sheet having a color between blue and red or other contrasting color, if dark blue ink has been used.
  • the absorptive capacity of the coating layer, and the penetrating power of the applied dye or paint solution should be so related that the color will not extend to the front surface of the Yoshino paper.
  • a ⁇ composite sheet for making stencils comprising a base of loose fibredafabric, a coating for said fabric adapted to be partially displaced and the remaining portions crushed to an opaque condition by type pressure, the majorportion of which coating is on that surface of said fabric to which the type pressure is to be applied, and a film of coloring matter pervious to ink after having been crushed by type blowsand/or removablev wholly or in part by such blows extending over the other and more thinly coated surface of said fabric.
  • a composite sheet for making stencils comprising a base of loose bred fabric, a coating for said fabric adapted to be partially displaced and the remaining portions crushed to an opaque condition by type pressure, the major portion of This does not Y which coatingV is on that surface of Asaid fabric to which the type pressure is to be applied, and a film of coloring matter pervious to ink after having been crushed by type blows, and/or removable wholly or in part by such blows extending over the other and more thinly coated surface of said fabric, said composite sheet being slightly transparent so that the portions of the front thereof not crushed by type blows also appears to be colored by reason of the color showing through the body thereof.
  • a paper stencil comprising a sheet of Yoshino paper saturated and coated with a solution forming a slightly transparent body when set, and a film of dark coloring matter pervious to ink after v having been crushed by type blows, and/or removable wholly or in part by such blows formed on one surface of said sheet, while the other surface thereof has limited opaque areas contrasting with said colored film and outlining the matter to be stencilled; whereby said outlined matter is rendered clearly legible by said contrast with said colored film as a background.
  • a stencil such as dened in claim 6 in which the major portion of said coating is located on the surface bearing said limited opaque areas and the latter are indented therein.
  • a stencil such as dened in claim 6 in which said opaque areas are substantially white in color.
  • the herein described method of rendering more legible a stencil composed of a sheet of Yoshino paper having a slightly transparent coating capable of being indented or crushed by type y blows which comprises applying to one surface of said coated sheet a film of coloring matter pervious to ink after having been crushed by type blows, and/ or removable wholly or in part by such blows which will not penetrate far below said surface, and indenting the legend to be stencilled by type blows on the other surface.
  • the herein described method of producing a legible stencil which comprises applying to one side of a sheet of loose bred paper a semitransparent coating which is capable of being broken down and rendered opaque and partly displaced by the blows of the type of a typewriting machine; applying to the other side of said coated sheet a film of colored material pervious to ink after having been crushed by type blows, and/or removable wholly or in part by such blows which will penetrate only part way through it; and indenting the legend to be stencilled by type blows against the first mentioned surface; whereby the colored lm shows through all portions of said typed sheet except the opaque areas lproduced by the type blows, the latter appearing in sharp contrast with such colored background, and permitting ink to pass therethrough when the stencil f is used for printing said legend upon the surface of an article placed beneath it.
