1892, No. 70,428; in England October To all whom it may concern.-

Be it known that I, FRANQOIS SOHREURS, a subject of the King of Belgium, and a resident of Brussels, in the Kingdom of Belgium, have invented certain new and useful Improvements in Apparatus for Printing and Dyeing Fabrics, (for which I have obtained Letters Patent in Belgium, No. 100,158, dated June 18, 1892, and No. 111,041, dated July 18, 1894.; in Great Britain, No. 19,079, dated October 24, 1892; in Italy, No. 67, dated June 30,1893; in Germany, No. 70,428, dated June 22, 1892, and in France, No. 222,450, dated June 18, 1892,) of which the following is a specification:

The present application has for its object to describe mechanical means whereby the process for printing and dyeing, being the subject-matter of my application for patent filed December 7, 1895, Serial No. 571,410, may be carried into effect; and it comprises means for causing the coloring material to penetrate the fabric and for feeding the stencils with said coloring material.

In the accompanying drawings, Figure 1 is an end elevation of a machine suitable for large-size work and for printing lengths of fabric. Fig. 2 is a transverse section on the line X Y, Fig. 1. Fig. 3 is a longitudinal elevation, and Fig. 4. a half-plan, of a modified construction of table for printing in different colors. Fig. 5 is a half-plan of a stencil used thereon. Fig. 6 is a perspective view, taken also in section, on line V W, showing more clearly the pads 19 and the division-plates h.

For large-size works and for the printing of lengths of fabrics I use a machine which, although producing the same effects, differs greatly from the former.

The gelatin stencil or perforated pattern A designed to be reproduced upon the fabric is stretched over a frame A, laid flat upon two cast-iron girders B, each of which girders carries a rack B. These girders B rest at 1) upon a roller 0, turning loosely upon the main shaft D, while the racks gear with toothed wheels E, keyed upon the shaft D, which imparts a rotary motion thereto. The shaft D also carries a cylinder F, covered with felt, the lower part of which cylinder dips in a tub or trough G containing the dye, while its upper part supports the stencil 0r perforated pattern A. On one end of the shaft D is keyed a large toothed wheel H,with which gear pinions k k, which communicate motion to two parallel shafts I I, carried by a series of supports L L, bolted to cross-girders M, supported by uprights T. To a bracket cast integrally with each support L a lever P is suspended by a pin 0. There are thus two series of levers P, one for each shaft I, each series carrying a bar Q, having the form of a knife, the cutting edge of which bears upon the cylinder F. The other and shorter arm of each lever P is terminated by a tooth S, engaging in the teeth of a ratchet-wheel R, keyed upon the shaft 1.

When the machine is set in motion in either direction, the cylinder F turns, and the felt covering it is saturated at each revolution with the liquid dye contained in the trough G. The racks B, driven by the wheels E, carry the stencil or pattern A away, the latter being throughout its length in contact with the felt covering of the cylinder F, which felt covering is saturated with dye. The fabric to be dyed, which is stretched over the stencil or pattern A, is hammered on its passage by the knives Q as it is carried away by the stencil over felt covered cylinder F, each stroke of the knife producing a line of dye upon the fabric except at the parts protected by the impermeable portions of the stencil. Owing to the rapidity of the strokes of the knives no break of continuity in the dyeing of the fabric is caused by the succession of these lines.

When the rack B has reached the end of its stroke, it may be caused to return inactive to its former position in order to continue the impressions upon a fresh length of fabric, and so on, or if the pieces of fabric requiring to be dyed are not too long the motion may be repeated in a reverse direction in order to dye a fresh piece at each stroke of the rack.

In the arrangement shown in Figs. 1 and 2 a table covered with a flat piece of felt similar to that shown in Figs. 3, 4, and 5 may be substituted for the cylinder F. In this case the table d, on which the felt i is secured, is made with a raised edge Z, which causes the table to retain on its surface a certain quantity of liquid for saturating the felt, thus avoiding the necessity of recharging the felt by means of rotary distributers, which would require the stencil or pattern A with which the felt is covered to be raised at each operation. This method of dyeing by means of transverse lines allows of continuous pieces of fabric being operated upon notwithstandin g that the machine operates intermittently. Another veryimportant consideration in the arrangement of the machine is that owing to the distribution of the dye on the felt being effected automatically by capillarity it is easy to produce a great number of different shades simultaneously. It is sufficient to cut-out the felt according to a given design and to impregnate each part with a suitable color, the feeding being effected through the under side of the table (1 at u by means of conduits e 6, connected to reservoirs ff, in which a constant level is maintained. It

is obvious that the different colors should in this case be separated by thoroughly watertight partitions of india-rubber, bitumen, or other suitable material, as shown at h h.

I claim as my invention 1. The combination of a stencil, a base of absorbent material for said stencil, means adapted to strike the fabrics upon the stencil when in contact with said absorbent material.

2. The combination of a stencil, a layer of absorbent material under said stencil, blades adapted to strike the fabric upon the said stencils and means adapted to move said stencil and the fabric .over the surface of said absorbent material.

3. The combination of a stencil, a rotary cylinder, an absorbent material surrounding the same, means adapted to strike the fabric upon said stencil, racks adapted to move said stencil and the fabric over the periphery of said cylinder, gears for operating said racks.

I11 testimony whereof I have signed this specification in the presence of two subscribing witnesses.
