To all whom it mayooiweritfl Be it known that we, JOHN LANCASTER and CHARLES WITTECK, both residents of the city,

county, and State of NewYork, have invented certain new and useful Improvements in Apparatus for Ornamenting orDecoratin'g Fab rics, of which the following is a specification. Our invention has especially referenceto ornamenting fabrics, more particularly grosgrain fabrics, and has for its object to produce a new and useful machine for ornamenting fabrics.

Our invention will be understood by referring to the accompanying drawings, in which i Figure 1 is a plan view of a machine for operating on the fabric. thereof on line 2 2 of Fig. 1. Fig. 3 is a broken away enlarged detail view of a pattern of the machine. Fig. 4. is a broken-away sectional detail view, on an enlarged scale, of the thread displacing or distorting roller. Fig. 5 is a broken-away sectional view of the distorting or displacing roller and thepattern-roller in operative relation. face view of the fabric as it comes from the machine, and Fig. 7 is a diagrammatic face view of the fabric after it has been pressed. Fig. 8 is a detail view, on an enlarged scale, showing the crossing of the threads, as here: inafter described. i

In the drawings, A indicates the bed or body of the fabric-manipulating machine, which said body is provided witha pattern, such'as the roller B, which maybecarried upon the, I shaft 12, mounted in bearings in the body A..

Adjacent to the shaft 19 is a frame or bracket 0, in which slide movable bearings D, which may be raised or lowered by adjusting screws E. These bearings carry a shaft ;F, upon which is mounted a warp-thread-displacing roller G. Thisroller G is adapted to coop;-

erate with the pattern-roller to displace the warp-threads of a fabric in the plane of the said fabric. roller is provided with a gear f, which meshes with-a large gear a, carried upon a shaft 0, which shaft also carries a gear 61, which meshes with a gear e, which in turn meshes with a gear g, carried upon the shaft h, which shaft Fig. 2 is a section Fig. 6 is a diagrammatic The shaft F of the displacing,

carriesapulley H, which is driven from a suitable source, power and motion being transmitted through the train of gearing to the thread-displacing roller G. The machine- Ibodyis also provided with a take-up beam I, whose shaft 1' is provided with a gear-wheel j, which meshes with a gear-wheel 7.2 on the driven shaft h, so that motion may be trans mittedtothe said take-up beam from the driven shaft; At the end of the machine opposite tothe take-up beam I we provide a cloth-beam J, which is shown as having a bolt of doubled clothwound upon it, which cloth .passes from the cloth-beam J to the clothbeam I'under a roller- K, which is free to be propelled by the cloth, over the pattern-roller B, which is also propelled by the cloth, and under another roller L, mounted in the frame and rotated by the cloth, and thence to the take-up beam I.

Therollers K and L are shown as provided with devices foradjusting them toward and from the pattern-roller B, the said adjusting devices being in the present case slotted plates Z and adjusting-screw and wing-nut devicesm, which screws pass through a lug n on the body. e y

3 The pattern-rolleris shownin detail in Fig, 3 and is exhibited as provided with a raised rubber pattern 19 on the periphery thereof. Its cooperating thread-displacing roller is shown as provided with thin suitablyset springy blades; 0, which may be slightly curved, as shown, and which are exhibited in Fig. l asseated in grooves q in the periphery of the roller G and held in place therein 1 by tongues r, seated in the said grooves and secured by screws .9. These blades maybe suitably arranged with respect to the axis of the roller-shaft.

I .The operation of the machine shown in Figs. 1 to l isas follows: The adjustingscrews E are adjusted to bring the blades 0 into contact with cloth passing over the pattern-r0ller B, as shown in Fig. 5; The fabric, which comes in a continuous roll or bolt, is folded along its median line 00 y and the edges brought together andpreferably secured by tacks. In this condition the cloth is wound upon the cloth-beam J and the clothbeam mounted in place. is then led, as shown, under the roller K, over the pattern-roller B, (see Fig. 5,) under the roller L, and thence passes to the take-up beam I, power being applied to the shaft h, so that the take-up beam'I will proceed to Wind .the cloth upon itself, drawing it over the course indicated from the cloth-beam J. The take-up beam, as will be seen, constitutes a cloth-propelling means. As the cloth passes over the pattern-roller it propels the said roller, and the weft-thread-displacing roller, being driven at a much greater speed than the speed of the cloth, has the effect of irregularly displacing the weft-threads 1 2 3 4 5 6 7, &c., of the thickness of the cloth which lies uppermost on the roller, the weftthreads of the lower thicknessof cloth being undisturbed. These weft-threads are not displaced throughout their entire length, but only at the portions thereof which are over the design of the pattern, so that one-half of the cloth receives by means of such displace ment a distinct trace of the pattern. This is clearly shown in Fig. 6, wherein in the left side of the cloth the weft-threads run in an undisturbed course, whereas in the righthand side of the cloth in this figure the weftthreads are shown as displaced or undulated sidewise out of their true alinement, thereby giving the appearance of a figure.

When the cloth has all been wound upon the take-up beam I, it is reeled from said beam to and through a pressing or calendering machine, and thereby the design on one thickness of the cloth is transferred also to the other thickness of the cloth, the displaced threads of the patterned side crossing the straight threads of the unpatterned side and serving as a die to impress the image of the pattern upon the unpatterned side, so that one side of the fabric is a counterpart of the other, but with this difference, that while the displaced weft-threads on the patterned side of the fabric remain displaced the weftthreads on the opposite side of the fabric remainv in their original straight condition, and whenever a displaced weft-thread of one portion of the doubled fabric crosses a straight thread of the other portion of the doubled fabric the straight thread is thereby indented, so that the resulting figures will present a solid portion, as c, surrounded by a line w. This effect is such as is shown in Fig. 7, wherein the fabric lying to the right of the median line is the portion of the fabric having the displaced weft-threads and the portion of the fabric lying to the left of the median line w 3 in Fig. 7 has its weft-threads straight. This operationis clearly indicated in Fig. 8, wherein the threads 1, 2, 3, 4, and 5 are the displaced weft-threads of the right-hand side of the pattern in Fig. 6 and the threads 00, x 00 $4, and m are the straight threads on the left-hand side of the pattern. This figure The doubled fabric shows the threads as much exaggerated; but it will be obvious that when the threads in the fabric are thus displaced the bent or displaced threadswill impress their form upon the left side of the fabric when pressed, so as to produce the effect shown in Fig. '7.

It will be obvious that the pattern-roller and Weft-thread-displacing roller may be Varied in form and construction and that they may be rotated in opposite directions.

What we claim, and desire to secure by Letters Patent, is

1. In a machine for ornamenting a completed strip of fabric, the combination of a traveling pattern, driving mechanism therefor, cloth-propelling means for bringing the fabric up to the pattern, and means for displacing the weft-threads of the fabric laterally in the plane of the fabric, the said displacing means cooperating with the pattern to reproduce the pattern on the fabric, substantially as described.
