CESAR CORRON, OF PARIS, FRANCE.

APPARATUS FOR DYEING.

SPECIFICATION forming part of Letters Patent No. 430,925, dated June 24, 1890. Application filed -l'annary 30, 1890- Serial No. 338,637. (No model.) Patented in France November 6, 1888, No. 194,033, and in England December 10, 1889, No.19,363.

To all whom it may concern.-

Be it known that I, CESAR CO'RRON, a citizen of the French Republic, residing in Paris, France, have invented certain new and useful Improvements in Apparatus for Dyeing, of which the following is a specification.

This invention has been patented in France, No. 194,033, dated November 6, 1888, and in England by patent No. 19,863, dated December 10, 1889.

My machine is designed for dyeing fabrics, and the elements which it comprises have for their object to maintain the width of the fabrics, instead of thickening them, while they are submitted to the operations of steeping in the dye and in the mordanting, rinsing, and clearing baths.

Another feature consists in the utilization of the same apparatus for dyeing and for mordanting or washing the fabric or brightening the dye, or, furthermore, for dyeing with the same apparatus in two colors or shades at a time. Finally, the fabric maintained at its natural width undergoes the f ulling operation by means of a presser-roller acting on the fabric' The arrangement and operation of my machine Will be clearly apparent from the description which will follow, with reference to the annexed drawings, wherein- Figure 1 is a side elevation of the machine. Fig. 2 is a plan. Fig. 3 is an elevation of the rear end. Fig. 4: is a vertical transverse section 011 the line 4 4 in Fig. 1. Fig. 5 is a longitudinal section. Figs. 6, 7, 8, and 9 are detail views of proper constructions of the driven rollers employed, and Figs. 10 and 11 are detail views of the steam-jet pipe employed.

The machine consists of atank A,in which are arranged three rollers B, C, and D, in order to support, conduct, and maintain at its full width the fabric to be dyed. The tank A contains, preferably, a water-tight tank or vat E, in which the fabric is folded in, such manner that if the vat A contains the dyeing-liquid the interior vat E may contain the bath of mordant or a rinsing or clearing bath; or, instead it may contain another bath of dye, (similar or not to the exterior bath.)

On each side of the vat A are arranged levers F F, balanced by counter-weights beneath and supporting a feeding-roller G, which revolves at a uniform speed, while at the same time the levers are reciprocated, turning on their pivots c 0. These parts, with the means for driving them, constitute the feeding mechanism for feeding the web of fabric into the tank and folding it therein in a regular pile.

Movement is transmitted to these several elements in the following mannerby connection which is established at the rear part of the machine. The principal shaft H receives movementby transmission through the pulleys P P. It carries a pinion a, which gears with the wheel I) on the shaft is. It is this shaft is which imparts oscillation to the levers F F by rods Z Z, which connect the crank-disks 'm m on the shaft 0 with the studs 17. non the levers. By varying as may be required the position of the crank-wrists the extent of the oscillations of the levers may be regulated. The shaft H carries at one extremity asprocket-wheel d, which drives a chain c, which passes over another sprocket-wheel f, which is of double width and loose on its pivot. This wheel f drives in its turn by a chain 9 a sprocket-wheel h on the axis of the feedingroller G. The other extremity of the shaft H carries two sprocket-Wheels, the one 0 driving by achain p a loose wheel (1 of double width, which in its turn actuates by a chain r the sprocket-- wheel .9 of the driven roller D. Finally, the other sprocket-wheel t on the shaft l-I drives by a chaina the roller 13, which in turn imparts motion (through a chain a) to the roller 0. By reason of these connections the three rollers B C D and the feeding-roller G turn in the same direction and at the same speed, so that the fabric travels very uniformly in the direction of the arrows o: in Figs. 1 and 5.

Over the feeding-r0ller G is arranged a presser-roller K, mounted likewise on the levers F F and pressing on the fabric under the action of the springs y 'y in order to full it. By its oscillating movement the feeding-roller folds the fabric in the vat E. The fabric leaves the latter, pulling uniformly from underneath, in order to circulate in the dyeingbath in the large tank, and to be thencelifted by the feeding-roller, which pulls it up again until the operation is finished. A sheet or plate L presses against the fabric while it is leaving the smaller vat and prevents the folds being drawn along unevenly. When it is necessary to lift the fabric in order to renew the color in the bath and fortify it, (that which is called in dyeing reviving the vat,) a carriage R, carried by wheels rolling on the sides of the tank is moved underneath the feedingroller G. This carriagehas a grated bottom. It receives in this position the fabric which is folded onto it. This carriage serves likewise to receive the fabric when the dyeing is finished.

The driving-rollers B C D, as well as the feeding-roller G, are arranged in order to hold the fabrics in their full width while they are moved within the tank. This result is obtained by a traction exercised laterally on the fabric at both sides at once, in order to compensate for the longitudinal stretchingupon the fabric, which tends to thicken it. Figs. 6 and 7 show separately, on a larger scale, an eXtensor-roller, which is well suited for producing this effect. It is composed of two disks of metal or wood 1; v, on which are fixed longitudinal bands 2, which serve to support helicoidal plates 10 w, of wood, metal, or other material. These two helicoidal plates are coiled inversely on opposite sides of the middle in such manner that both shall act on the fabric to pull it laterally toward both sides at once. In certain cases one or other of the driving-rollers of helicoidal plates, or all of them, if the class of fabric permits, may be replaced by rollers such as that shown in Figs. 8 and 9, and which is formed of straight bars. If only one tank is desired, the vat E may be replaced by a sort of cage or grating, permitting the dye to pass through it.

I add to the apparatus in the tank A beneath the fabric one or several perforated tubes M, for the injection of steam. This steam-pipe may likewise be utilized for cooperating in distending the frabric, and thereby assisting in the extension of it in width, to do which it is sufficient, as shown on a larger scale in Figs. 10 and 11, to form the tube with oblique holes extending in divergent directions on each side of the middle part, as shown in Fig. 11.

This apparatus may be applied to the dyeing of all fabrics in width. When it is used for dyeing of velvets, two thicknesses are superposed with their piles together,in order that the piles shall not be matted down by passing under the rollers.

I claim as the distinctive features of my machine for the dyeing of fabrics- 1. The combination, with a dyeing-tank and rollers therein for guiding the fabric to be dyed, of a revolving feeding-roller arranged above the tank, upright arms at opposite sides stantially as set forth.

of the tank on which said roller is mounted, and mechanism for oscillating said arms, whereby the fabric is drawn from the tank over the roller, and by its alternate movements is folded back and forth within the tank.

2. The combination, with a dyeing-tank containing a dyeing-bath, of a smaller Watertight vat within it suitable for containing a mordanting, rinsing, or brightening bath, or a second dyeing-bath, feeding apparatus for delivering the fabric into said smaller vat in folds, positively-driven rollers for drawing it out therefrom and circulating it through the dyeing-tank and thence back to said feeding apparatus, and driving mechanism for operating said feeding apparatus and rollers.

3. The combination,with a dyeing-tank, of

a reciprocating feeding and folding roller mounted over the tank and adapted to deliver the fabric into the tank-in folds, and positively-driven rollers within the tank and around which the fabric is passed, said rollers drawing the fabric from the pile into which it is folded and delivering it to the reciprocating feeding and folding roller, sub

4. In a dyeing apparatus, the combination, with a dyeing-tank, of a steam-pipe therein, over which the fabric to be dyed is passed,

said pipe being perforated with holes for dis- 1 charging steam and directing it against said fabric, said holes extending obliquely and in opposite directions on each side of the center of the pipe, substantially as set forth.

5. The combination, with a dyeing-tank, of a feeding apparatus for folding the fabric thereinto, consisting of a power-driven feeding-roller mounted above the tank and caused to reciprocate bodily as it revolves, with mech anism for so reciprocating it, and a compressor-roller arranged to press against said feeding-roller and thereby to full the fabric as the latter is passed between them.

6. The combination, with a dyeing-tank, of a feeding apparatus consisting of a reciprocating feeding-roller mounted over the tank adapted to deliver the fabric into the tank in folds, positively-driven rollers within the tank, over which the fabric is passed and conducted thence to the feeding-roller, and driving mechanism for revolving the feeding-roller and the tank-rollers in the same direction and at approximately the same surface speed, whereby they determine the circulation of the fabric within and from the tank and its return thereto, and mechanism for reciprocating the feeding-roller.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
