MEANS FOR STENCIL-PRINTING.

SPECIFICATION forming part of Letters Patent N 0. 443,801, dated December 30, 1890.

Application filed March 2, 1889. Serial No. 301,781, (No model.)

To all whom it may concern:

Be it known that we, JOHN W. SMITH, of Boston, Massachusetts, and HENRY L. HEISKELL, of Oxen Hill, Prince Georges County, Mary- 5 land, citizens of the United States, have invented certain new and useful Improvements in Means forStencil-Printing; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying draw- 1ngs, and to the letters of reference marked thereon,which formapart of this specification.

:5 This invention has relation to that class of devices for reproducing or making manifold copies of letters, music, &c.; and it has for its objects the production of a convenientlyshaped, simple, and economical device of that character that will obviate many disadvantages heretofore experienced with such devices.

To these ends our invention, which we denominate the milliograph, consists in certain novel features in the construction, arrangement, and combination of parts, substantially as hereinafter described, and specifically pointed out in the subjoined claims.

In the accompanying drawings, Figure 1 is 0 a perspective view of the herein-described milliograph as arranged, for transportation and when it is not in use, the corners of the several parts thereof being broken away to d sclose the relative position of said parts.

3 5 Fig. 2 is a similar view of our device, showing the same as arranged for use. Fig. 3 is a detail perspective view of a plate, which serves when the device is not in use as a lid or cover therefor, protect-in g the interior parts thereof, and when in use as a surface upon which to cut the stencil. Fig. 4 is a transverse section taken on the line 00 w of Fig. 1. Fig. 5 is a transverse section through 3/ y of Fig. 2.

Like letters of reference mark the same parts in the several views.

The box or receptacle of our milliograph is composed of the leaves or parts A A, which are hinged together on one side, as shown at a a, and provided with pivoted hooks b, and

pins Z) on their opposite sides, as shown in Figs. 1 and 2. The upper portion or leaf A of said receptacle is constructed of longitudinal and transverse strips a a, thus forming a frame simply, while the lower portion thereof is made preferably of a block of wood having its edge recessed or cut away (see Figs. 4 and 5) to form upwardly and outwardly extending projections, designated, respectively, by the letters 0 and 0'. Upon the proj ection c the ink pad or supply D rests. This ink-supply may be a plate formed of metal, glass, or other suitable material having the ink spread upon it in suitable quantity, or, if preferred, it may consist of cloth,felt,rub-

ber, rubber cloth, or other suitable pervious I or absorbent material saturated with ink and 7 adapted when pressure is applied to give off 4 the ink.

B designates a plate, (shown in detail in Fig. 3,) preferably constructed of zinc or some similar metal, and formed with depending projections B and lips or flanges B, extending horizontally from the extremity of said projection B. An inverted flanged pan is thus formed, which is designed to form a lid or cover for the inilliograph when the latter is not being used, protecting the interior parts of the same from exterior influences, such as air and dust, the former of which would cause evaporation and consequent loss or deterioration of the ink, and the latter gumming thereof, besides necessitating constant cleaning of said interior parts by settling thereon, as will be readily understood. The platelS also forms a surface upon which to cut the stencil.

When it is desired to use our improved milliograph, it is necessary to remove said pan, and such removal is eifected by unlocking the receptacle or box and raising the upper leaf thereof, when, as is obvious, access is had to the interior of said receptacle and the pan easily lifted therefrom.

The method of taking copies of circulars, letters, &c., by means of the hereinbefore-described device is as follows: A stencil C is made in any usual manner by perforating the outline of the letters, figures, &c., and for this purpose any of the ordinary and wcll-knowu perforating-pens may be employed. The lid or pan upon which the stencil has been made having been removed and the stencil placed face downward in contact with the ink pads 5 or supply, the device is ready for operation. now place the sheet of paper upon which the copy is to be taken face downward on said reversed stencil and apply pressure to its upper surface, which pressure forces the ink up xo through the punctures of said stencil onto said copy-sheet. Should the supply of ink become exhausted before the desired number of copies have been made, the pad or plate upon which it was spread can be readily rer moved, respread with ink, and replaced. One means referred to for applying the required pressure is shown in Fig. 2, in which is delineated a roller E, the shaft F of which is journaled in the respective extremities of a 2o 1' ra me G, which is provided with a rearwardlyextending projection G, having a handle ll thereon for convenience in using. \Ve do not i wish to be understood as limiting ourselves to this form of means for applying pressure,

as any suitable means maybe employed without departing from the spirit of our invention.

Although we have described a particularlyconstructed frame upon which to mount our ink-pad and stencil, we do not desire to be 0 understood as limiting ourselves to such construction. When desirable to make impressions by other means than the roller described,

we will build up our printing-surface differently. For instance, we may take a sheet of metal as the ink-pad, ink it, place the reversed stencil upon it and the paper upon the stencil when we desire to make the impression by passing it through a pair of suitable rolls, the object in such case being to make the structure as thin as possible. \Ve may also use a plain wooden block for the ink-pad of such thickness that when the stencil is added the thickness will about equal the length of type. This structure could then be used in 5 a printing or lithographic press. By this means of printing through a reversed stencil many objections which exist when an inked roller is passed over a stencil are removed. 15 very rolling by the inked roller tends to gum up, clog, and till the stencils, and specially prepared very expensive paper must be used. llhereisagreat ten dency, also, to soil the hands and the paper.

In operating this invention nothing but clean paper and clean rolls are used while taking impressions, and every impression tends rather to clean than clog upthc stencil. The stencil, always lying upon the inked surface, may be made of the fiimsiest oiled or waxed paper, splendid practical results havingbeen obtained with the paper used to wrap candies or caramels in.

By spreading different colors of ink upon the plate or pad-as, for instance, in the spaces marked 3 and f in Fig. 5the copy maybe made of different colors; or, such dilterentcolored inks maybe dilferently arranged-as, for instance, in sueha manner asto print a seal, trade-mark, or autograph in a color different from the body of the copy.

Having thus fully described our invention, what we claim, and desire to secure by Letters Patent in the linited States, is-

The combination, with a base A, having an upwardly-exten(ling project-ion c in its central portion and ontwardly-extending projections 0 upon its sides, of an ink-pad supported by the said upward projection, a frame hinged to the said base surrounding the upward projection and resting upon the outward projections thereon, and a metallic cover hav ing dependent flanged sides contained between the said base and frame, the top of the said cover being above the said pad, as described.

In testimony whereof we alti x our signatures in presence of two witnesses.
