ALBERT I-IABERSTROH, OF BOSTON, MASSACHUSETTS.

ART OF MAKING STENCILS.

SPECIFICATION forming part of Letters Patent N0. 628,315, dated July 4, 1899.

Applicant nea February 13,1899. serrait. 705,418. (No model.)

modes of making stencils of the kind thatare to be used for stenciling walls, ceilings, fabrics, 85o., or other surfaces that are desired to be decorated, and it is carried out as follows, reference beinghad to the accompanying drawings, wherein- Figure l represents a top plan view of my V'improved stencil, and Fig. 2 represents a cross-section on the line 2 2, shown in Fig. l."

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

In making my improved stencil I proceed as follows: I rst take a porous or perforated sheet A, which I term the base, preferably made of textile or fibrous material, or, if so desired, ne Woven wire-netting may be used as a material for such base. To such porous` perforated base I apply a suitable illing B, soluble in water. As a material for such lilling I use any suitable paint or plastic composition, soluble in Water, which I cause to be impregnated or molded between the meshes of the porous .or perforated base, so as to be firmly attached thereto.' In using such paint or plastic material as a filling it may be applied to the perforated or porous base by means of a brush or spatula or similar tool,

according to the nature and consistency of such filling. After such soluble filling is dry or has become set I cover such portions of the filling that are to remain affixed to the base with suitable paint or composition, nonsoluble in Water, and after such paint has becorne dryI wash the stencil with water, causing the non-painted portions thereof to be dissolved and washed away, leaving the perforated or porous base bare at such washedaway portions, thus producing a stencil which may be used for the purpose of applying coloring or plastic material to walls, ceilings,

fabrics, or other surfaces that are to be decorated.

What I wish to secure by Letters Patent and claim is The herein-described method of making stencils, which consists in impregnating a foraxninous base with a filling of paint soluble in water, allowing the same to dry, then covering portions of such illing with a water proof p aint non-soluble in Water, allowing the same to dry and finally washing the same with a liquid to dissolve the nonpainted portions and removing the same, leaving the base at such washed-away portions bare, substantially as specified.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
