STENCIL.

To all whom it may concern Be it known that I, ARTHUR B. BosrwloK, a citizen of the United States, and a resident of the city of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Stencils.

' ;alfl. ted portions of the stencil in place.

in full lines inthe This invention relates to stencils and the process of making same. In an ordinary stencil the openings in the plate through which the color prints the line or figure would, if the line were continuous, cut the plate into pieces and the pieces would fall apart.

One of the objects of my invention is to produce a stencil with the separated parts held in their proper places yet the stencil when used, will print a continuous line or figure.

Another object of n invention is to produce a stencil by means of which intricate and artistic designs, letters, etc., may be printed and have the elfect of hand painting,

Another object is to produce which will print embossed letters or de: signs, the lines of which will hecontinuous.

Other objects will appear from the hereinafter description.

Referring to the drawings in which the same reference character represent the same part in the several views, Figure l is the front or; the printing face of the stencil made according to my invention. Fig. 2 is a cross section on an enlarged scale taken on line 2 of Fig. l, and showing the pad back of the stencil. Fig. 3 is a similar view showing the constituent parts of the stencil shown in Fig. 2, separated from each other. Fig. 4 is an enlarged face view of one word of the stencil shown in Fig. 1. This figure shows in dotted lines behind the opening in the stencil means for holding the cut-out or separate portions of the word in place.

6 is a sheet of oil paper or other material through which the ink or colors will not pass, which is used to protect the pad 7 from the ink when the stencil is used.

In constructing this stencil I proceed as follows: Lead foil is temporarily fastened to a glass with an adhesive substance. The foil is then coated with wax. or .designs are then cut through the wax and foil to the glass. This can be done with a sharp pointed instrument such as a sewing needle. After the letters, figures or designs are thus cut, the uncut portions 3 of the ,body of the foil are carefully covered with shellac and then a fine thin silk fabric 4 is applied. Thesilk adheres to the she'llacked uncut ortions of the stencil. The whole 1s then p aced in water and the adhesive material which holds the foil 'to softened, permitting the foil to he removed from the glass, the silk fabrlc holdlng the separated portions of the stencil in place, and the cut-away portions 2 of the stencil remain attached to the glass. Instead of using the, fabric to hold these separated parts of the foil in place, I may use .any other material or I wires! v If only onecolor ,is to heused .inrsuch' a stencil the color is applied to-theback-of. the

. used v I employ the divisional strips 5- to prevent the colors from mixing or running into each other. These division strips are placed back of the fabric 4 and they are made with their front edges sharp and the rear ends flaring. These dlVlSlOIl strips form pockets into which the different colored inks are placed, and said strips effectually separate one ink from the other. As oil paper or fabric is placed on the back of these division strips so that the pad 7 will not become soiled by the ink when the pad is forced down by the press. This pad 7 is of soft material, such as thick felt, and will readily enter into the different pockets and ink divisions, and force the ink through the fabric 4 and throughthe openings 2 in the .foil to make the impres- In Fig. 1, as above stated, the stencil is made to print the letters as shown, and the representation of a rose. The division pieces 5 are so placed that different colored inks may be used. For example, the letters and the stem, leaves and buds of the flower are to be printed in green. The division strips 5 and 5 are so placed that the ink inside of 5' will print red and that portion between 5* and 5 will print pink. The ink between 5 and 5 will also print pink and that inside of 5 will print yellow.

In Figs. 4 and 5 I have shown on a large scale the word Roses to more clearly illustrate certain portions of my invention. If the letters 0 and e of this word for instance, were cut to print a continuous line, the inside portions 3 of these letters would fall out unless some means were used for holding them in position. The silk fabric glued to these cut-away portions as well as the main body of the stencil, holds them in place so that in printing, the ink passesthrough this fabric and through the I cut-0ut potions of the foil and prints the letters and e as well as the letters r, s and s in a continuous line, so that the result does not look like a stencil but has the effect of hand painting or brush work.

Instead of using the division pieces -5 to confine the ink in position and prevent the different colors running into each other, I have found that if I take a pad made of several thicknesses of ink absorbing material 30, as shown in Fig. 10, and divide it into several parts, 31, 32 and 33 corresponding to the colors to be printed, I can obtain good results. In constructing such a pad I apply to the cut edges 34 thereof a cement and then ink the different parts of the pad with the different colors desired and reassemble the arts. Th'ecemented edges 34 prevent the ink in one section from running into the ink Figs. 6, 7 or 8.

in the other section, and in printing the, edges will form a sharp line or division between the inks. When the pad is reassembled it is only necessary to place it inproper position behind the stencil and apply pres-' pad and through the cut-out portions of the stencil and leave the proper impression on the paper or material being printed.

This construction permits me to produce a finer line than when the division pieces 5 are used and no undesirable breaks appear in the printing.

When it is desired to print embossed letters or designs, I use a stencil as shown in In this construction instead of making the stencil out of thin material, 'I make it out of thick material to make the plate more durable. In this construction the plate from which the stencil is formed is sure when the ink will be forced out o the marked 20. The design to be printed, as

here shown A, which is marked 21 the drawing, represents the separate parts of the letter and 23 the spaces surrounding the same.

The separate parts are supported or secured in place to the main portion of the plate and, as shown in Figs. 6 and 7, by thin is out through the plate. 22

webs 24 being left integral with the body of the plate, said webs extending across the spaces 23 about midway between the thickness of the plate. In using this stencil so constructed, he printing face is placed against the surface upon which the printing 1s to be done. The ink is then applied to the back of the plate and is forced 1n the spaces 23. The ink fills the spaces up to the back surface of the plate, the 24 bein such as to permit the ink to flow under t e same and in the space on the surface being printed so that no breaks Wlll appear in the printing. Upon removing the stenc'il from the printed surface, the 1nk that may be on the back of the web 24 will flow off said web into the nearest openin in the plate and the space 23 will be fille up completely and there will be a continuous line printed and raised substantially the thickness of the plate.

Instead of leaving the web 24 in the construction of the design, the whole design may be made by cutting the spaces 23 clear through the plate and then the separated portions 22 may be retained in position by fine threads, wires or similar means 24 secured to the back of the plate and to suitable position on the cut-away portions 22. The plate can be used in the same manner for embossing, as shown in Fi' 6.

As many changes coul be made in the above construction and many apparently widely different embodiments of my invention could be made without departing from location of the web contained in the above description or shown scribed and all statements of the scope of the 7 might be said to fall therebetween.

Such stencil prints are invariably stifi' and clumsy.
