FREDERICK EUGENE DROVVN, OF PAXVTUCKET, RHODE ISLAND.

APPARATUS FOR BLEACHING.

SPECIFICATION forming part of Letters Patent No. 441,946, dated December 2, 1890.

Application filed March 24., 1890. Serial No. 345,153. (No model.)

To to whom it may concern:

Be it known that I, FREDERICK EUGENE DROWN, a citizen of the United States, residing at Pawtucket, in the county of Providence and State of Rhode Island, have invented a new and useful Apparatus for Bleaching and Dyeing Textile Fabrics, Braids, and Yarns, of which the following is a specification.

My invention relates to an improved apparatus for the purpose; and my invention has for its object the bleaching and dyeing of cotton and other textile fabrics and braids arranged in a specific manner. The pieces of fabric sewed together at the ends are wound in a continuous manner many thousand yards in length upon a portable roll, which can be arranged to fit, first, the winding-machine; second, the bleaching and dyeing vessel; third, the finishing machinery. By having its ends arranged for this purpose, or, as is more usually the casein practice,it is arranged to be placed on a shaft adapted to the ma- The fabric in bulk wound on a portable roll is placed in the bleaching and dyeing vessel and therein treated in a thin sheet with the bleaching or dyeing agents, solutions, steam, and gases, or air above or below the normal pressure of the atmosphere, assisting the action of the bleaching and dyeing agents or exhausting them from the fabric by pressing the fabric between squeezingrolls, and after the bleaching or dyeing operations have terminated removing the fabric from the bleaching or dyeing vessel in bulk wound on a portable. roll. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1 is an end elevation of the apparatus and vessel A and the fabric in the form of a roll Wound on a portable roll B and in position to be lowered into vessel A. Fig. 2 is a longitudinal vertical section of the vessel A on line a of Fig. 1. Fig. 3 is an elevation of the fabric in the form of a roll wound on a roll B. Fig. 4: is an end view of the roll B. Fig. 5 is an elevation of the braid Wound in the form of a roll onto a roll B, having sheets or plates a fixed to roll B, between which the braid is wound. Fig. 6 is a plan of slotted guide (t in vessel A. Fig. 7 is a transverse section of the vessel A and an opposite end elevation of the apparatus from that shown in Fig. 1. Fig. 8 is a transverse vertical section of another form of the vessel A on line 0 of Fig. 9. Fig. 9 is a plan of another form of the vessel A in which two chambers A and A are connected together, havinga space between same for the squeezing-rolls G and having tight-closing lids 7e and k.

Similar letters refer to similar parts through out the several views.

In bleaching cotton fabric by my method I proceed as follows: The fabric is wound in the form of a roll onto a portable roll B in a continuous manner many thousand yards in length. The fabric is then placed in thevessel A with the portable roll B supported by and fixed to rotate with the rotating shafts E and F. Another portable roll B, the same as roll B, is fixed to rotate with the rotating shafts E and F. The end of fabric on roll 13 is then carried up over the roll a and through the slotted guide a and between the squeezing-rolls G and fastened around the roll B. The fabric maybe carried directly onto roll B without going through the guide a or over the roll 0 and treated in this manner. The lid A is then closed and firmly fastened and the fabric is ready to be treated in the vessel A. The fabric is passed in a thin sheet through the bleaching and dyeing agents and pressed between the squeezingrolls G by rotating the rolls B and B, and the squeezingrolls G Winding the fabric off of roll B and onto roll B, or, vice versa, off of roll 13 and onto roll B by reversing the rotating meel1- anism.

By Winding and unwinding the fabric and passing it in a thin sheet in contact with the bleaching and dyeing agents in vessel A, and assisting the action of said agents or exhausting them from the fabric by pressing the fabric between squeezing-rolls G, the fabric can be Very uniformly and expeditiously treated by the different agents and can be washed and squeezed, and, furthermore, the steps required for different qualities of bleaching or dyeing or for different kinds of fabrics can be successfully carried out without removing.

the fabric from the vessel A.

As the different steps in bleaching and d yeing and the agents used can be varied to a tated and the end of the fabric made fast to' roll B and the lid A closed and made steamtight and all pipes connectingwith the vessel A closed, the valve 6 in vent-pipe It is opened and the valve d in steam -pipe I opened and steam blown through vesselA to expel the air. Then valve 6? isclosed and valve (Z also closed and sufficient water admitted to condense the steam and form a vacuum in the vesselA through water-pipe J and perforated water-pipe 6 The valves (1 and (Z in pipe K, connecting vessel A with the alkali-tank L, are then opened and the alkali solutions in tank L drawn intovessel A. Valve (1 is then closed and a steam-pressure admitted through steam-pipe I. The rolls B and B and the squeezing-rolls G are then rotated, winding the fabric onto roll B. After the fabric has been rewoundonto roll 13 the motion is reversed, thus reversing the motion of roll 13 and B and the squeezing-rolls G and rewinding the fabric again upon the roll 13.

\Vhen the fabric has been sufficientlytreated with the hot alkali solutions, the valve (Z is opened and the solution forced back into tank L by steam-pressure admitted through pipe I. Valves (Z and d are now closed and valve e in vent-pipe H opened andthe valve 6 in steam-pipe O, which is connected with the perforated steanrpipe c in vessel A, is opened,

and the treatment of the fabric on roll B resumed by passing said fabric between the squeezing-rolls G, thence over the perforated steam-pipe e, and winding it up on roll B. In admitting hot solutions into vessel A, I prefer to form a vacuum in vessel A, as aforesaid, by admitting steam and then condensing it by spray of water. In ejecting hot solutions from vessel A, I prefer to do so by steam-pressure admitted through steampipe I. In forming a vacuum and also an air-pressure in vessel A when cold solutions are used I prefer to use a vacuum and aircompression pump T. After alkali treatments have terminated and the vessel A blown out free from alkali solutions the fabric is washed with water in the following manner: The valve d in water-pipe J, connecting with the perforated pipe e in vessel A, is

opened, and the valve 6 in vent-pipe II and pipes connecting with the vessel A closed.

7 Then valvesf andf in pipeR are opened, and

valve 9 in suction-pipew', connecting pipe R with vacuunrpump T, is also opened, and the vacuum is at once formed in vessel A. Valve 9 is then closed and valve f opened and the chlorine solution in tank S drawn into vessel A, followed by pneumatic pressure, formed by air-compressor T as follows: Valve f is closed, and valve g in dischargepipe 7), connecting pipe R with air-compressor T, is opened and an air-pressure maintained in vessel A. Valve 9 is then closed.

After the fabric has been treated in the manner heretofore described by passing it in a thin sheet through the solutions by unwinding it from roll B and rewinding it onto roll B and the fabric pressed'bet-ween the squeezing-rolls G the chlorine solution is drawnback into vessel S by vacuum-pump T as follows: The valve 9 in suction-pipe to, connecting tank S with vacuum-pump T, is opened and a Vacuum formed in tank S. Val-vef in pipe R is then opened, and valve 6 in ventpipe V II also opened and the solution withdrawn into tank S. The fabric is now washed and squeezed as before.

' In souring,thc treatment is the same as with chlorine. A vacuum is formed in vessel A and the diluted acid is drawn'in from vessel U through valves f and f and pipe R, followed by pneumatic pressure, if desired. After treatment the solutions are withdrawn into the tank U and the fabric washed and squeezed as before. This concludes one series of steps for bleaching cotton fabric.

For jute fabric, permanganates and sulphurous acid solutions can be used alternately, or weak hypochlorites and alkali solutions and other agents for the bleaching and dyeing of differentkinds offabrics. After bleaching, the lid A is taken off and the fabric taken out of the vessel A in the form of a roll on a portable roll B. Lid A is arranged hinged to one side of vessel A and counterbalanced over a frame Y by weight X and the roll B taken out by a hoist 71 The air-compressor and exhaust-pump T, mounted upon an air chamber or receiver arranged to contain an air-pressure above or below the normal pressure of the atmosphere, is connected to tanks S and U by dischargepipe 2) and suction-pipe w and to vessel A by discharge-pipe 1; and suction-pipe w and the pipe B. By this arrangement of connecting pipes the air can be compressed in or exhausted from the vessel A, the acid-tank U, or the chlorine-tank S.

The vessel A can be made in many different forms and shapes. I have shown in Fig. 8-21. transverse vertical section of the vessel A on line 0 of Fig. 9, which is a plan two chambers A and A connected together, having a space between same for the squeezerolls G, the perforated steam-pipe e, and the perforated water-pipe c and having tightclosing lids 7s and 7c. The fabric wound on roll B is placed in vessel A and the roll B connected to shaft E, which has a steam-tight joint with vessel A The shaft E is arranged to rotate the roll B. The other end of roll B is supported by a short shaft F fixed to removable arms, which are fastened to the side of the vessel A The fabric on roll B is passed by the water-pipe e and between the squeezeroll G by the steam-pipe e and wound upon roll B, which is arranged in vessel A and is connected to the shafts E and F similar to the roll B with shafts E and F Then the fabric has been Wound upon roll B, the motion of shafts E E and the rolls G is refielr sed and the fabric again wound upon ro The foregoing described modified form of.

the vessel A is adapted more particularly for the bleaching and dyeing of textile fabrics and yarns in a rope form. In this case the portable rolls B and B have circular plates a fixed to each end, between which the fabric or yarns are wound in a rope form, the same as thread upon a spool, and the fabric or yarn as it travels in vessel A from roll B to B, or vice versa, is wound in a traverse manner by a traverse guide arranged in the vessel A.

Having herein described my method and apparatus for the purpose, I claim and desire to secure by Letters Patent- .1. In the bleaching and dyeing of textile fabrics and yarns, a bleaching and dyeing vessel having two chambers connected together and having tight-closing lids, and portable rolls having plates fixed to their ends, upon which the fabric and yarns are wound in a rope form in a traverse manner to facilitate its travel in the bleaching and dyeing vessel and its removal therefrom, substantially as described.
