UNITED STATES VICTOR ROSATO, OF NEW YORK, N. Y.

STENCILING' METHOD.

Application filed September 15, 1927. Serial No. 219,612.

This invention relates generally to stenciling methods, and has more articular reference to a device for stenciling silk material or the like.

The invention has for an object the provision of a device of the class mentioned which is of simple durable construction, ef ficient in operation, and which can be manufactured, and sold at a reasonable cost.

The invention consists in providing a wooden table having a layer of concrete thereon covered by a piece of felt. A covering of oil cloth rests upon the felt and a canvas on top of the oil cloth and the sllk material or other equivalent material to be" stenciled is laid upon the canvas. Frames are next provided and bolting cloth commonly used in milling, pulp and flour mills for screening is secured tightly across the bottoms of the frames. Negatives of the designs to be stenciled are formed on this bolting material, suitable margins being pro vided on the bolting material near the edges of the frames. The frames are provided with means for adjusting their positions so that registering of stenciled work is possible.

Dye and gum material suitably mixed is placed on the top of the painted part of the bolting material and a roller with an associated scraper is moved over the bolting material, forcing thedye mixture through the unpainted part of the material and onto the silk, the frames having been previously placed on the silk.

For further comprehension of the invention and the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claimsin which the various novel features of the invention are more particularly set forth.

Referring to the accompanying drawing,

forming .a material part of this disclosure:

. of the aperture.

Fig. 7 is a side view thereof, with the roller hanging downwards.

Fig. 8 is a vertical sectional View taken on the line 88 of Fig. 2.

The reference numeral 10 indicates generally a wooden table top supported bylegs llconnected by braces 12. One side of the tabletop is provided with vertical side 13 having a plurality of pins 14 clamped as at 1 1 on the said side and secured thereto by thumb screw 14. A layer of concrete 15 is secured to the top of the table, and felt material 16 is attached to the top of the concrete. Oil cloth 17 is secured to the felt 16, and canvas 17 is placed on top of oil cloth 16. Silk materiallS, to be stenciled,

rests upon the canvas.

Frames 19 have a screen cloth generally used by flour and pulp mills known as bolting cloth 20 secured across their bottoms by nails 2O which are driven into the frame 19 through the reenforcededging20. Painted portion 21 forming a negative of the design to be stenciled is on the bolting cloth.

Setting screws 22 are screwed in the side walls of frames 20 and are placed adjacent the vertical side 13 oftable 10. By means of screws 22, the angle of the frame may be adjusted as desired with respect to the side of the table. I V

The frames 19 have brackets 23 attached to the tops thereof. Each of the brackets is formed with a central aperture 2 L. At one end a slot 25 connects with the aperture, and a bushing 26 is forced into the other end An L-shaped member 27 has one arm projecting from slot 25, and the-other slidably in aperture 24. A screw 28 is rotatably connected to the last men tioned arm, as at 29, and this screw threadedly engages the bushing 26, and the free end of the screw has a slot 30. A turning tool may be engaged in slot 30, and the screw 28 turned so as to move the L-member. The projecting arms of the L-members abut against the pins 14' to hold the frames against displacement, and the relative position of the frames to the pins 14, or directly stated, the relative positions of the frames 19 to the silk material 18 may be changed and adjusted by turning screws 28.

A roller and scraper 3O used in conjunction with the device consists of a pair of brackets 31, each being formed with a pair of opposite abutments 32. The brackets 31 are attached to the ends of a board 33, or

aluminum plate, formed with a bottom scraping edge 34. Links 35 are pivotally connected to the brackets and a roller 36 is connected between the links. The links 35 and the abutments 32 are so arranged that the roller 36 may be on one side of the board 33 with the links against the abutments as shown in full lines in Fig. (5, or on the opposite side of the board with the links against the opposite abutments as shown by dot-dash lines 37.

The operation of the device consists in applying ink, or like on the roller 36, and then manually working the roller and scraper 30'' back and forth on the material 20 until the ink is forced through the unpainted part of the material 20 onto the silk 18. The roller 36 should preferably be of a rubber compound. or may be made of any suitable material, but it instead of silk 1S, carpet or velvet is to be stenciled, the roller should be covered with felt. A steam line 38 may be provided to aid in drying the stenciled material. One color is stenciled at a time, and when one color has dried, the frame may be replaced with other frames holding the stenciling negatives of the next color. The frames may be properly registered by adjusting screws 23 so that the arms of L-mem hers L T abut the pins 14.

\Vhile I have illustrated and described my invention with some degree of particularity, I realize that in practice various alterations therein may be made. I therefore reserve the right and privilege of changing the details or otherwise altering the arrangen'ient of the correlated parts without departing from the. spirit or the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent is:

1. In a device of the class described, the combination with a table for supporting material to be stenciled and provided with a vertical member with clamps and projecting pins of tames for supporting stencils of bolting cloth and arranged for engaging upon the table, brackets secured to the frames and having a central aperture communicative with an end slot, L-members slidably mounted in the apertures and having one arm projecting from the said end slots and arranged for engagement against the said pins for registering the frames relative to the table, bushings engaged in the said apertures, and screws threadedly engaging in the bushings and rotatively connected with the L-members.

2. In a device of the class described, the combination with a table for supporting material to be stenciled and provided with a vertical member with clamps and projecting pins of frames for supporting stencils and arranged for engaging upon the table, brackets secured to the frames and having a central aperture communicative with an end slot, L-members slidably mounted in the apertures and having one arm projecting from the said end slots and arranged for engagement against the said pins for registering the frames relative to the table, and a. means for adjusting the positions of the L- mcmhers relation to the said brackets.

3. In a. device of the class described, the combination with a table for supporting material to be stenciled and provided with a vertical member with clamps and projecting pins of frames for supporting stencils and arranged for engaging upon the table, brackets secured to the frames and having a central aperture communicative with an end slot, L-members slidably mounted in the apertures and arranged for asraunint! various fixed positions and having one arm projecting from the said end slots and arranged for engagement against the said pins for registeringthe frames relative to the table.

4. A. registering device, comprising a bracket arranged for connection on a frame, and having a central aperture col'nn'iunieatire with an end slot, and L-memhers slidahly mounted in the aperture, and arranged for assuming various fixed positions, and having one of its arms projecting from the said end slot and capable of engagement with a positioning pin for registering the bracket relative thereto. i

In testimony whereof I have afiixed my signature.
