DYEINGr-MACHINE.

Specification of Letters Patent.

Patented Mar. 2, i920.

Application led October 26, 1917. Serial No. 198,567.

To all w/Lom t may concern:

Be it kno-wn that I, HOWARD M. DUDLEY, a citizen of the United States, residing in the city of Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain new and useful improvements in Dyeing-Machines, of which the following is a full., clear, and exact specifi-l cation.

My invention relates 4to dyeing machines and refers particularly to machines suitable for the dyeing ofteXtile fibers, and like materials, by means of a circulating liquid.

One object of my invention is a device whereby textile fibers may be dyed evenly and uniformly while in a compressed condition.

Another object of my invention is a device whereby a liquid may be passed uniformly and thoroughly through a compressed mass of fiber.

Another object of my invention is a device whereby the formation of channels may be prevented while passing| a liquid through a compressed mass of fiber.

Another object of my invention is a device whereby the condition of the treated liber may be determined without interrupting the process of treatment.

Another object of my invention is a device compressing ai testing device whereby the condition of the treated fiber may be accurately determined without opening the dyeing chamber.

These and other objects of the device of my invention will be evident upon a consideration of my specification, drawings and claim.

Great difficulty is experienced in obtaining even and uniform dyeings of textile fibers in those machines in which the fiber is treated while under pressure to the action of a dyeing liquid. Under these conditions the liquid has a tendency to form channels or passages through the fiber,through which more liquid passes than through other portions of the liber, thus causing uneven results.

It is evident that when liber is compressed between two plates having openings with parallel sides, the liquid forced through-the openings will be impinged in a ser1es of liquid columns against the fiber forcing itself therethrough in a series of channels,

the intermediate portions of the mass being less affected bythe liquid.

It further evident that unless the liquid pressure is absolutely equal upon all parts of the foraminous plates, more liquid will be forced through some of the holes than through others causing uneven dyeings.

AIt is further evident that au equal liquid pressure must be maintained at all times throughout the entiremass. I

.My device accomplishes all of these three vital elements of successful dyeing and pre sents a method whereby all portions of the fiber will Vbe treated equally by the impinged liquid whereby the formation of channels is prevented, whereby the liquid pressure will be absolutely equalized over the entire foraminous plate and whereby a uniform, liquid pressure will be maintained throughout the iiber mass.

In order to equalize the liquid pressure over the entire foraminous plate, I pass the liquid int-o the device through a series of conduits distributed below a foraminous plate, thus distributing the liquid as evenly as possible, from these the liquid passes through a foraminous plate, thus breaking up any currents that have been formed, into a chamber from which it passes through a second foraminous plate into the fiber mass. This chamber between the two foraminous plates causes a complete equalization of the f liquid pressure and allows an absolutely uniform and equal amount of liquid to pass through all portions of the fiber mass.

In order to prevent the formation of channels through the mass due to the impinging of Vliquid columns upon the liber, the foraminous plate of my device upon which the liber rests consists of a series of inwardly projecting members, thus presenting a maximum of liber surface to the ac:- tion of the liquid and causing it to penetrate the entire mass in an equal and complete manner.

In order to maintain a uniform liquid pressure throughout', the entire liber mass, the two foraminous plates of my device, between which the fiber is compressed, are eX- actly similar in constructie-11, the exit of thc liquid from the mass therefore being under the same conditions as its entrance into the mass.

`-By means of my testing device, the condition of the dyed ber may be determined a-t any time without opening' the dyeing chamber or interrupting the operation, the value of which device is evident.

l also provide means whereby the liquid may be passed in opposite directions through the fiber when desired.

Having thus broadly described my invention: l give the following example of one form of my device. i

y The device of my invention, as illustrated, comprises a receptacle having the side wall 20, within which is the foraminous plate 21, resting upon the annular otlset'22 of the side wall 20. Spaced above the plate 21, and supported therefrom by the annular member 23, is a foraminous plate 24. The bottom 25 of the receptacle contains a series of converging tubes 26, 26, 26, the interior ends of lthe tubes 27, 27, 27 being extended upwardly. rThe outward ends of the tubes 26, 26, 26 terminate in a chamber 28 within the extended portion 29 of the receptacle. Removable from and slidable within the receptacle is a foraminous plate 30. Aremovable top 31 contains a series of converging tubes 32, 32, 32 similar to those in the bottom 25, the interior ends of the tubes 33,

33, 33 being extended downwardly. The outward ends of the tubes 32, 32, 32 terminate in a chamber 34 within the extended portion 35 of the top. The top 311also carries the oraminous plate 36, and the y downwardly extended portion 37 of the top is capable of abutment upon the plate 30. Screw bolts 38, 38 passing through openings in the ang'e 39 of the top 31 and threaded in the holes in the flange 40 of the wall 20 allow of the top `being forced downwardly into the receptacle. Bolt eyes 41, 41 are inserted into the top 31 as a means for raising the top.

A testing tube, shown in cross-section in Fig.7 is similarV and proportionate to the larger'devce and comprises the wall 42 and the foraminous plates 43, 44, 45 and 46 similar to the plates 36, 30, 24 and 21 respectively. The threaded hollow members .47 and 48, threaded with the interior of the wall 42 enable the compression of the fiber v101. The lower portion of the wall 42 is connected with the pipe 49 by means of the bushing 50. The pipe 49 carries the valve '51 and is connected with the chamber 52 by means of the conduit 53. rlhe upper portion of the wall 42 is connected with the .pipe 54 by means of the bushing 55. lThe pipe 54 carries the valve 56 and is connected to the chamber 93 by the conduit 58. By means of the bushings 50 and 55, the testing device can be removed from connection with the pipes 49 and 54 to allow of charging the same or oit examining the contents.

Plates 24 and 30, as shown in Figs. 4 and 5, consist of a series of serrated rings 60, 60, supported by the members 61, 61.

Plates 21 and 36, as shown in Fig. 6consist of a plate 'having circular openings 63, 63 therein. ,l

The extended top member 35 is connected to the pipe 64 which in turn is connected to the pipe 65 by means ot' the flange coupling lThe extended bottom member 29 is con. Ynected to the pipe 69, which carries the'valve 70, and is connected vto the discharge chamber of the pump 68. Y

The pipe 71 connecting the members 35 and 29 carries the valves 72 and 73 and is connectedr with the pipe 74 emptying into the top of the reserve tank 75.

The bottom of thereserve tank 75 is connected to the pipe 76, carrying the valve 77 and connected to the receiving chamber of the pump 68. A pipe 78 carrying the valve 79 connects a dissolving tank, not shown, with the receiving chamber of the .pump 68. A pipe 80, carrying the valve 81, enters the chamber 28. p i

In the modification ot the top member 31 and the bottom member 25, as shown in Figs. 8 and 9, the tubes 26, 26 andV 32, 32 are replaced by the troughs or ` conduits 82, 82, open at the portion toward the interior of the receptacle. p

rlhe modification of the plates 24 and 30, shown in Figs. 10 and 11, comprises a series lll of parallel and intercepting bars 84, 84k having extended points or members 85, 85.

In the modification of the plates 21 and 36, shown in Figs. 12 and 13, the holes 86, 86 are square instead of round.

The operation of the device is as follows The liber mass 100 is placed within the receptacle and upon the plate 24. Plate 30 is then placed upon the liber mass, and the top 31 lowered into place. The pipe 61 is connected to the pipe 65 by means of the coupling 66, and the member 35 connected to the pipe 71 by means oi the nipple 91. rlhe screw bolts 38, 38 are then inserted and screwed down, the member 37 pressing the plate 30 inwardly until the desired pressure is obtained upon the fiber mass, the pipe 65 sliding into the-bushing 96, and the nipple 91 being turned to take care of the downward movement of the top. The testing device is charged with the fiber mass 101, and placed in position. All of the valves are closed with the exception of valves 79, 70, 51, 56 and 72, and the pump 68 started.- rlhe liquid thus passes from the dissolving tank, not shown, through the pipe 78, the pump 68, the pipe 69, the pipes 26, 26, the chamber 52, the plate 21, the chamber 92, the plate .24, the ber chamber and the ber 100 therein, the plate 30, the chamber 57, the plate 36, the chamber 93, the tubes 32, 32, the pipes 71 and 74 into the reserve tank 75. When sufficient liquid has been introduced into the reserve tank, the valve 79 is closed and valve 77 opened,- the liquid then having a continuous circulation in the direction mentioned above. At the same time the liquid passes upwardly through the testing device and the fiber 101 therein.

When it is desired to reverse the flow of the liquid, valves 70 and 72 are closed and valves 67 and 7 3 are opened, thus allowing the liquid to pass in a reverse direction through the device. From time to time, as desired, the condition of the fiber in the testing device may be determined by closing valves 51 and 56 and removing the device as previously described. The liquid may be drained oil through the pipe 80, and water may be introduced for washing the fiber by means of the pipe 94C carrying the valve 95.

I do not limit myseltl to the particular size, shape, number or arrangement oi parts as described and shown, all of which may be varied without going beyond the scope of my invention as described and claimed.

What I claim is In a dyeing machine, in combination, a receptacle having imperforate sides, two foraminous plates within and extending across the receptacle, a iber chamber between the two plates and the sides of the receptacle, means for increasing and decreasing the size of the fiber chamber, two oraminous plates spaced outwardly from the irst two plates, a reserve tank, a conduit connecting the upper portion o' the receptacle with the reserve tank, a pump, a conduit connecting the reserve tank with the pump, curved tubular members above and below the foraminous plates so arranged that a liquid may be continuously forced through the tubular members, the plates, the ber chamber and the reserve tank in either direction.
