This invention frelates to a dye jig forruse in connection with the finishing of textile material Or'for like use, and has for one of its objects to provide a construction with an independent simplified drive for each tank.

Another object of this invention is the provision of a Construction in which an electric motor may be utilized for independently driving each jig.

I Another object of this'invention is the provision of a dyejig construction in which the.

jigs will each have an independent drive mounted Completely upon each jig to cause each jig to be morepaccessible and permit the operator to freely walk Y completely around each tank if desired.V

A further object of this invention is the provision ofY a construction which will be Vquiet in operation and one which will have a minimum vibrationA and wear upon the parts. v

A still further object Vof this invention is the provision of a control means which may.

be operated from either side of each tank and in which the control of the different feed rolls will be simultaneous.

' With these'and other objects in view, the invention consists' of certain novel features ofc'on'struction, as will bemore fully described, and particularly pointed out in the appended claims. Y Y Y Y In the accompanyingdrawings:`

Y l j Fig. 5 is a perspective skeleton viewof the control means for operating the clutches for the feed rolls'. V i i f In the operation of dye jigs it has been usual to connect the feed rolls Aofa series ofdye jig tanks to a'lcommon operating drive shaft extending longitudinally along a length of tanks by such means as bevel gears or the like for operating the dierent feed rolls and to control the operation of each feed roll by a suitable clutch mechanism.v lIt has been customary to use considerable additional gearing mechanism when the power is furnished by an electric motor as the motor must i travel at a relatively high rate of speed, compared to the .rotation desired on the feed rolls ofthe tank, necessitating a train of several reduction gears of different sizes intermeshing to obtain the desired reduction before the shaft is rotated, and in order to substantially reduce this usual gearingl and provide an independent operation of each tank, I have kutilized an electric motor for directly operating separate drive shafts for each tank j and driving each ofthe feed rolls from the drive shaft by worm .and worm gears, thus providing asingle'pair'of quiet running gears and an independent drive foreach unit; and the following is a detailed description of the present embodimentv of this inventi on illustrating the preferred means by which these advantageous results may be accomplished. A j 1 With reference tothe drawings, 10 desig-V nates the tank which vis supported by suitable frame work llhhavinnfl feet 12 to rest upon the floor or other suitable support. Within each tank there is a speciallyk constructed metal frame which supports guide rolls 13, 14, y,15 and 16 over which the traveling web 17 of textile fabric or the like is conducted from a package 18 rotating about an aXis 19 to the package 20 rotated about the aXis 21 'or vice-versa through the bath contained in the tank 10.

Y This above kdescribed portion of the devic-epis somewhat the usual construction, and the invention relates more particularly to the driving of the feed rolls 22 and 23 which are mounted upon suitable shafts 24 and 25.

shaft 24 and 25 intermeshing with worms on the drive shaft 28.

An electric motor 3l has its axis of rotation axially aligned with the drive shaft 28 and is coupled thereto by a suitable coupling 32 for-rotating the drive shaft 28. rIhe coupling 33 is also interpositioned in the :drive shaft 28 for convenience of assembly.

The worm and worm gears are enclosed in a housing 34 and 35 Vwhich also provides bearings 36 and 37 at each end thereof for the better support of the drive shaft 28. v The housing 34 is liquid tight to contain a lubricant for the gears to assist the quiet operation of the device and prevent Wear on the operating parts and also by having the lubricant entirely enclosed in this manner it cannot be spattered into the treating tank to soil the goods. Y

Each of the clutches 27 are provided with a collar 38 grooved as at 39, in which a ring 40 is located. Pins4l and 42 extend from diametrically opposite sides of the ring, and

\ in order to shift the clutch member 43 to and from engagement with its companionmember 44, I have mounted a bracket 45 on the frame 46 of the device which supports an upwardly extending pivot pin 47 and lon this pin I have mounted the hub member 48 from which there extends bifurcated arms 49, slotted as at 50 to engage the pins 41 and 42 of the ring `40, so that movement of the lever 51 will control the action of each of the rolls by moving'the clutch into or out of operative position.

The members 48 are also provided with arms 52 extending laterally from the hubs and are connected by means of a link-53 soy that when either of the levers 51 which eX- Oi i tend from opposite sides of the machine are moved by the operator, the opposite clutch and lever is also moved, thus both clutches may be operated in unison from either side e of the apparatus to accomplish direction of rotation desired.'

lIn operation when the roll 22 is functioning to lfeed the web by drawing it from the package 20, the clutch 27 of the shaft 24 is in engagement to cause a drive of the package 18 and the clutch on the shaft 25 connected therewith to freelyV rotate. When it is desired to draw the cloth from package 18 to wind `it upon package 2OA the roll 23 is driven and the clutch on roll 22 will be positionel to permit the same freely to rotate, thus it will be observed that a shifting of a lever 51 at one side of the machine to throw the clutch into operative position will simultaneously cause a movement ofthe clutch on the other side of the machine to throw the clutch. outY of engagement, while the arrangement is Such that there is an intermediate position in which both clutches are in neutral.

By the construction which I have above described an independent drive is provided for each tank, thus eliminating the common connecting shaft for a series of tanks and permitting the operator to move freely and completely about each tank for inspection and manipulation of the work as desired. Also by this construction I provide a thirty to one, or any desired reduction, in the speed of rotation by the spiral gears, enabling the feed roll to be driven directly from the electric motor shaft without the necessity for providing a train of intermeshing spur gears, .and also by enclosing the gears I am enabled to run them in lubricant and provide a more quiet and eicient drive and one in which the dye bath and work are free from soil. Also as each ljig is independent a constant or variable speed motor may be provided to run different tanks at different speeds, thus allowing fargreater flexibility of action and manipulation of the work.

In some instances the web is reeled -directly on the roll 22 or 23 and in such instances the use of the variable speed motor enables me to draw the web through the heating bath at a substantially constant speed if desired `therebyzeliminating a variation in .speed due tothevarying diameter of the reeled package. Also by the use of a variable speed motor I am enabled to operate the tank at different speeds for different classes of work, thus permitting .the work to be passed through the tank slowly in some cases or faster for other classes of work.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.
