HOWARD MI. DUDLEY, 0F PHILADELPHIA, PENNSYLVANIA.

DYEING-MACHINE.

Application filed February 15, 1917.

To all whom it may concern:

Be it known that I, HOWARD M. DUDLEY, a citizen of the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have in vented certain new and useful Improvements in Dyeing-Machines, of which the following is a specification.

My invention relates to a dyeing machine and refers particularly to a machine adapted for the dyeing of textile fibers compressed within a dyeing chamber, the dyeing being accomplished by the forced passage of the dye liquor through the fiber mass.

Among the objects of my invention is a dyeing machine particularly suitable for the dyeing of warps in the ball, whereby the condition of the fiber may be accurately and readily judged at any stage of the treatment without opening the dyeing chamber and whereby even results may be obtained without disturbing the fiber to be dyed.

Another object of my invention is a dyeing machine in which the dyed goods may be after-treated with water, steam, air, or other materials or substances without han-' dling the dyed goods.

Other objects of my invention will be evident upon a consideration of my specification and claims.

I have found that the even or uneven dyeing results obtained in a machine of this general character depend largely upon the particular shape of the openings through which the dye liquor enters the fiber mass, and that unevenness can be prevented by the use of openings of a particular shape, the conformation of which enables the liquor to spread itself through the fiber mass without the formation of channels of flow.

I have further found that this desirable result can be obtained if the fiber-mass is supported in the dyeing chamber upon a series of upwardly and downwardly converging elements, as spindles, arranged along longitudinally disposed openings for the passage of the dye-liquor or other substances or material.

I have further found that the evenness of the dyeings and treatments may be enhanced by inclosing the fiber in a series of containers and passing the treating liquid through these containers and the fiber contained therein.

In the use of many dyestuffs it is necessary, after dyeing to treat the dyed goods with Specification of Letters Patent.

water for washing purposes, or with solutions of chemicals such as metallic salts or oxidizing products, for the purpose of aftertreatment, or with oxygen or air for oxidizing or drying purposes. In the following of these after-treatments it is essential that every portion of the dyed goods be thoroughly and uniformily treated and that the operation be performed as readily and quickly aS possible. All of these results are obtainable by the use of the device of my invention, in which the goods are placed in the dyeing chamber and then rapidly, easily and completely dyed and after-treated without further handling of the goods and without the formation of channels by the liquids employed. The device therefore insures even and uniform results with a minimum of time, labor and expense.

One form of my device is shown in the accompanying drawings in which similar parts are designated by similar numerals.

The outer portion of the dyeing machine, as illustrated, comprises the upwardly converging cover 12 removably attached to the annular member 13 by the screw bolts 14;, 14, the member 13 being movably attached to the shell 15 by means of the screw bolts 16, 16, the shell 15 being attached to the shell 17 by the bolts 18,18,the shell 17 being attached to the downwardly converging shell, 19, by the bolts 20, 20, the shell 19 being attached to the centrifugal pump 21 by the bolts 22, 22. The pipe 23 connects the chamber of the pump 21 with the threeway pipe 2 1-, the latter having the pipes 25, 26 and 27 fitted respectively with the valves 28, 29 and 30. The pipe 25 is connected with an air compressor not shown; the pipe 26 opens into the air and the pipe 27 may be connected with a drain or receptacle as desired. The pump 21 is connected with the pipe 31, which in turn is connected with the pipe 32, the latter being connected with the pipe 33 carrying the valve 31, the pipe carrying the valve 36 and the pipe 37 carrying the valve 38. The pipe 33 is connected with a dye-dissolving tank, not shown, the pipe 35 is connected with a liquor-reserve tank 39, and the pipe 37 is connected with a water supply.

The object of the reserve tank 39 is to allow of the production and use of a larger quantity of dye liquor than is necessary to fill the dyeing device. By this means the strength of the dye-liquor may be governed to meet the requirements of each individual dyeing operation, and the liquid maintained in a condition where the dye will not be precipitated upon the fiber. It also allows a more uniform supply of liquor to the pump 21.

The annular member 13 is of angular shape, one arm of which 410 fits within the interior face of the shell 15 and is slidable therein, its vertical movement being governed by means of the screw- bolts 16, 16 which thread in the projection d1, 411 of the shell 15.

The pipe 12 connects the upper portion of the interior of the shell 15 with the liquor reserve tank 39 and carries the valve 13. The pipe 1 1, carrying the valve 15 may be connected with a drain, not shown.

A. fixed fiber-supporting chamber d6 is situated within the shells 15 and 17 and comprises a series of parallel grate-bars 17 17, the bars of which carry upwardly and downwardly disposed pointed spindles 18, 18, allowing the series of openings 19, 19 between the grate-bars. A series of upwardly extending lugs 7 0, 7 0' are fixedly attached to the outer periphery of the bottom of the tray 96, and an annular imperforate side member 71 integral with the gratebars 17 17 extends upwardly to the top of the lugs 70, 7 0, said side member 71 being integral with and fixedly attached to the interior faces of the lugs 7 O, 70.

The lugs 70, 7 0 are vertically movable chamber 88.

within the lug- chambers 72, 72 of the shell 15. The interior of the fiber-supporting chamber 16 is therefore formed by the gratebars e7, 17 and the annular side member 71.

The device is provided with a number of removable fiber-supporting chambers 73, 7 1, the construction of which is similar to that of the chamber 46, each chamber being capable of a position over and upon the chamber beneath it. A similar chamber 88 is used as a top chamber, no fiber being contained therein.

In order to facilitate reference to the various chambers, they will hereafter be referred to as the top chamber 51, the liquor supply chamber 53, and the lower cham.

ber 54.

A sample dyeing machine 55 eXactly'similar to the one above described except that it is in smaller proportion and carries the threaded closed top 56 instead of the top 12, is connected to the liquor-supply chamber 53 by the pipe 57 carrying the valve 58. The upper portion of the sample machine 55 is connected with a pipe 59, capable of being revolved into the position shown by the dotted line 60.

A. pipe 61 connects the thermometer 62 with the liquor-supply chamber 54c, the pipe (51 being extendedv beyond. the thermometer into the pipe 63, capable of being revolved into the position shown by the dotted line or.

A perforated steam pipe 55 is within the liquor supply chamber 53.

The top chamber 51 contains a series of round pointed rods, 66, (56, supported by the diamond shaped bars 67, 67. A. series of similar bars, 68, 8, supported by the members 69. 69 are. situated within the lower chamber 51, and a series of similar bars 75, are situated within the chamber of the pump 21.

The operation of the lows The top 12, the annular member 13 and the fiber-carrying chambers 88, 73 and 7e are removed. The fiber-carrying chamber 41-6 is properly packed with the fiber to be treated, and the fiber-carrying chambers 73 and 71-. which have been previously packed. with the fiber, are placed thereon and the chamber 88 placed upon the chamber The annular member 13 is then introduced and moved downwardly by means of the screw bolts 16, 16 threaded in the projecting members 11, 11, the annular member 13 pressing upon the lugs of the This downward movement of the annular member 13 is continued until the fiber-carrying chambers 16, S8, 73 and 74k are pressed firmly upon each other. Goods aresimilarly placed in the sample device 55. Valves 15, 28, 29, 30, 38 and 34. are closed and valves 58, 43 and 36 are device is as fol.

opened, and the pipes 59 and 63 situated as shown by the dotted lines 60 and 64. The necessary dyestuff having been dissolved in the dye-dissolving tank, not :shown, connected with the pipe 33, the valve 34: is opened and the centrifugal pump 21 is started. The pump 21 forces the dye liquor upwardly between the rods 75, and 68, 68, in the chamber of the pump 21 and the bottom chamber 54, the liquor supply chamber 53, the foraminous bottoms of the fibercarrying chambers 46, 74: and 73, and the goods contained therein, and the chamber 88. As the liquor rises it will pass through the overflow pipe 12 into the liquor-reserve tank 39, from which it will pass through the pipe35 into the pump 21, thus allowing of a continuous circulation of the dye-liquor upwardly through the device. During this operation the dye-liquor is forced upwardly through the sample device 55 and the goods contained therein. The temperature is varied by means of steam introduced through the steam-pipe 65 and the temperature determined by means of the thermometer 62. From time to time, the valve 58 is closed, the top 56 of the sample device 55 removed and the goods contained therein examined to determine their condition, and the top 56 replaced and the valve 58 opened and the dyeing operation continued until a test of the goods in the sample device shows them to be properly dyed.

The next step is the removal of the dye liquor contained in the device. This is accomplished by closing valves 43, 3tand 86, opening valve 30 and stopping the pump 21. This allows all of the dye-liquor in the device to drain through the pipe 27 into a suitable receptacle for future use if desired.

The next step is that of washing the ex cess of dye-liquor from the goods and this is accomplished by closing valve 30 and opening valves 38 and 4:5, and starting pump 21. This allows fresh water to enter through the pipes 37, 32 and 31 into the pump 21 which forces it upwardly through the (levies and the goods contained therein and through the over-flow pipe 1 1 into a drain.

The next step is that of oxidizing the dyeings, if oxidizable, by means of air or of d the goods. This is accomplished by plat .g the pipes 59 and 63 in the position shown by the full lines, placing the top 12 upon the device, affixing it thereto by means of the screw-bolts 1st, 14, and attaching the upper open end of the top 12 to a vacuum or suction pump, not shown. The valves anc 38 are closed, the valve 29 is opened, and the pump 21 stopped. The vacuum or suction pump attached to the top 12 thus draws air through the pipe 26 upwardly through the device and the goods contained therein. If the amount of air thus obtained is insufficient for the purposes desired, the valve 28 connecting the pipe 25 with an air compressor may be opened and the valve 29 closed and thus sullicient air may be obtained. It is evident that the air passing through. the pipes 25 and 26 may be heated before its introduction into the device, if desired.

The particular formation of the foraminous bottoms of the fiber-carrying chambers 16, 73 and 7t and the chamber 88 causes the dye liquor to be spread out and evenly distributed through the goods, causing even dyoings, the similarity of the foraminous bottoms causes a more regular pressure of the dye liquor within. the fiber and the rod members (36, 66; (38, (S8 and 75, 75 intensify this distribution and regularity of pressure.

It is to be further noted that the goods are dyed, washed and after-treated or dried without handling, and that all of the operations are under exactly the same conditions, and that the condition of the goods bcing dyed or treated can be determined at any time during the operation without in terrnpting the operation by examining the goods in the sample device Figs. 7 and 8 illustrate a modified form of the rods (56, (3G; 68, 68 and 75, 75, the rods 76, 76 being round and the pointed or tapered ends of the form.

In the modification shown in Figs. 9, 10, 12 and 13, the foraminous bottom of the fiber-carrying chamber comprises a series of upwardly and downwardly pointed square spindles 77, 77, arranged along the grate-bars 7S, 7 8, allowing the openings 79, 79, while the grate- bars 78, 78 have square openings 80, 80 to allow of the passage of the liquid. In this modification the various chambers contain a series of pointed square rods 81, 81, supported by the members 82, 82, and the exterior shells of the device are rectangular in form, as shown.

In the modification shown in Fig. 14, the grate-bars 83, 83 of the foraminons bottom of the fiber-carrying chambers have round pointed spindles, 8 1', 81-, with the elongated openings 85, 85 and the round openings 86, 86. In this device, I prefer to have the fibercarrying chambers and the sheell 15 of a circular form as shown.

In the modification shown in Fig. 11, the top 12 of Fig. 1 is replaced by the top 87.
