2 Claims:

My invention relates to an improvement in .dye-

Heretofore, it has, beencustomary. to drive the so-called winding-out roll. from theperiphery' of i is to reduce any backlashspeed. of the winding. roll. can. bermade proper and suitable for thework being done,.and-with out any regard for, the speed jof cloth usedqinn dyeing. l

This, invention, therefore, consists in:.an.,at-:

tachment which may be usedonpresent dye jigs of various designs. and which will .greatly reduce the time necessary to get the-.clothponto and off.

: the machine rolls.

One of the primary objects of this invention;

is the time saving element, meaning; the provision of a construction whereby the manipulation.

of the cloth can be done in a'small fraction of 30. vthe time hitherto required.

By actual test, I have provided a machinein:v

which the time of unwinding the cloth from the machine is ,reducedto. about, one-fourth, .at the same time doing a better j0b:;With1 .arresultant 351' more uniform winding of the cloth on-the storage roll as it leaves the machine.

As a preliminary to, a fuller description of de-.

tails and operation, it may besstatedthat cloth to be dyed usually comes wrapped around a wood- .en core through which a steel shaft passes so that the ends protrude beyond the rolls. When the machine-is entirely freeof cloth; the wooden core with the roll of dyed cloth is removed: This operation of taking the cloth ofiof the machine generally requires about forty five minutes; and i Fig. 1 is a top. plan View brokenout through.

Referring to the drawings: This dye jig consists. essentially of a dye tank or vatl, for containing dye fluid, and in the bottom of the tank orvat-is a suitable drain connection 2. The tank or vat. is generally enclosed within a suitable structure .orframe A which latter carries the rolls and structure above the tank;

Near the bottom of the tankers-two rolls 3, Figs. 2,. 3 and 4, the purpose of which is to guide the. clothor goods as it: is. passed through the dye fluid.:.

Above .the tank .are two rolls 4 and 4, upon whichzzthee cloth isgwound and unwound as it passes ,;through the dye- On one end, of these rolls! and-A are keyedbevelgears 5 and 5'. Bevel gears Sand 5' meshwithbevel gearsgfi and 6', Fig.:3.., These. gears .6 and 6" have longsleeves I andfI, andarle fitted loosely on the drive shaft 8.1 However,. the sleeves-are fitted withfriction clutches!) .and'B soconstructed that the driving hUbSL10fthe .clutches are keyedto the shaft'8. A clutch'ishifterl 0 is provided andmounted tightly on theshifter shaft, .l I. Depending arms I2 are mountedon: shifter shaft II, and engage upstanding-qleversillr Levers l3 are keyedto the. endsmfitwolever. shafts I4,which terminate in the .:.operator,: so that .by, a partial. rotation of either lever handle I5, thexoperator,.moves the clutchg'shifter and thereby engages oneof the clutches..;and at. the same time disengages the other. By engagingqa clutch, he connects that clutch andgear tothe drive-shaft 8, and causes the roll.' toyrotate with theishaft. Likewise, by disengaging the clutch; he disconnects (the ,roll from the.drive shaft. This action is necessary, due to the fact that the unwinding roll is revolving-at continually changing revolutions per minute dueto the different diameters of the cloth due to winding or unwinding on the rolls.

In Fig. 4 the cloth is shown by line I6, winding onto. roll 4 from roll 4. Just as the roll 4 gets practically emptyof cloth, if it is desired to pass handles 15,: located within convenient reach of the cloth back through the dye, the operating levers I5 are brought to central position (otherwise neutral) as shown in Figs. 3 and 4, which disengages both clutches and stops both rolls. The cloth is now passed to the opposite side of roll 4, as shown by dotted line H, then the operating lever is shifted in the direction of arrow D, which causes the clutch to engage and. start up roll 4 in the direction of arrow B, which continues until all the cloth is wound on the roll 4. In this Way the cloth can be passed back and forth through the dye as many times as necessary.

However, suppose the cloth has received sufficient dye and practically all the cloth is Wound mechanism, just as the cloth is unwound from roll 4, Fig. 4, the rolls are stopped by again shifting operating levers I5 to neutral, as shown in Figs. 3 and 4, when the end of the cloth is carried up over the top roll I8, as shown by dotted line l9. Roll I8 is now started in the direction of the arrow E by shifting the lever 20, which throws clutch 2! on driving shaft 8 into engagement as shown in Fig. 4. Roll I8 continues to run at a constant number of revolutions per minute, until it has received all the cloth in the machine, after which the roll with the cloth is removed from the machine.

A desirable feature of my present invention resides in the location, construction, and method of driving this upper roll I3. It will be noted the roll is placed at a suitable location above and tween rolls 4 and 4.

roll. Suitable means are provided for driving the roll I8 from the drive shaft 8, and claw clutch means 2l25 is provided for disengaging said drive from the drive shaft.

The driving means above referred to for roll I8, as shown in dotted lines in Fig. 1, consists of a pair of bevel gears 22 on the shafts 35 and36 (see Figs. 1 and 3), with belt and pulleys, or

The clutch "nected with the shifter lever 28 is pull-rod -26,

terminating in an upturned handle 21, on the end of the machine opposite from the lever 28 so that the clutch 2| can be operated from either side of the machine. The members 2| and 25 of the clutch mechanism have inwardly projecting ratchet teeth, one surface of which teeth slopes in opposite directions in said members, whereby to cause them to push apart when the speed of the top roll exceeds the speed of the drive shaft, whereby said roll will finally stop without the at-' tention of the operator.

From the foregoing description; it will be apparent that roll I8 winds up the cloth thereon with increasing speed the longer it runs, and until the completion of the winding and the roll is ready to be 'removed from the machine, due. to the fact that the rotary motion is transmitted at the axial center of the roll instead of at the I means 2I-'25, the roll would have a tendency to spool or core on the shaft.

travel faster by momentum than the driving mechanism, and thereby automatically throw the clutch out of gear, so that the roll would come to a stop automatically.

The driving-head 28, Fig. 1, for roll I8 is shown in detail in Figs. 5, 6 and 7, and it will be noticed that there is a square counterbored hole 31 about one and one-half inches square, in the end of the head. An approved means for supporting the roll I8 is indicated in Fig. 5. This preferably consists of a square steel shaft 38 turned round for a bearing on one end 39 and left; square on the other end to engage the driving-head 28 on the shaft 36 through the square hole 31.

The roll I8 is preferably in the form of a hollow wooden spool or core, as shown in Fig. 5. On this spool or core the cloth is wound. Wedge bushings 4| are provided to tighten the Wood This complete spool or core with or without the cloth Wound thereon, is removable from the machine.

This-attachment is used for placing the cloth in the machine as well as removing it.

For example: A roll of cloth 30 to be dyed is brought to and placed in the machine as shown in Figs. 4 and 5, and when raised into proper position, the square end of the shaft 38 is placed in the square hole 31 in drive head 28, and the round end 39 is placed in stand-box 29. The roll will. then .be large, full of cloth, and in the machine as'shown at'38, Figs. 4 and 5. The end of the cloth is then brought down past roller 4 and on around the two rollers 3 and up to roller 4.

Roller 4 is put inoperation and winds the cloth Suitable bearing supports are provided for the upon same, see arrow C, Fig. 4.

I have shown in the'foregoing how cloth can be unwound from the machine onto roll I8, as shown by dottedline I9. However, in the event cloth is wound on either of rolls 4 or 4', and it is desired to remove same from the rolls without passing ,it through the dye, this can be done by threading the end of cloth on either of rolls 4 or 4' up' and directly upon the periphery of roll I8.

An adjustable friction band brake maybe providedas shown at 3|, this acting as a brake to retard the roll I8 when same is idling and unwinding the cloth onto the machine roller. It will be noted clutch 2| is disengaged and the roll is idling when the cloth is being unwound therefrom.

similar friction band brakes may be applied to the ends of rollers 4 and 4', as illustrated by numerals 3| (Figs. 1 and 4) for retarding these rolls when they are idling. T

After the cloth has been drawn back and forth through the dye as'many times as required, it maybe 'desirable'to rinse out the cloth. This is done by draining out the dye through the drain 2, whereupon the vat I is filled and refilled with fresh waterand the cloth is drawn back and forth therethrough until suificiently rinsed, after which it may be threaded into and wound over the roll I8, as hereinbefore described, completely dyed and ready for removal from the machine.

It is desirable that the rolls 4, 4 and I8 be all located over the vat, and that roll I 8 is preferably located above and in the space between rolls 4 and 4 so that drainage from each roll will drop directly into the vat below.

I claim:

1. The combinationof a frame, a tank having guide rollers therein,winding rolls journaled on the-frame above the tank, a drive-shaft, gears for transmitting rotary motion from the drive shaft to the said rolls, clutch mechanism on the drive shaft, means for shifting the clutch mechanism to cause motion to be transmitted to one roll or the other, a storage roll located above the drive shaft and parallel with the first-mentioned rolls, transmission means from the drive shaft to the axial center of the storage roll characterized by a shaft, gears, a pulley on said shaft and one loose on the drive shaft, a belt extending over said pulleys, the hub of the pulley on the driveshaft having claw teeth to form a clutch member, a clutch member keyed to slide on the drive shaft, and means within the control of the operator for shifting the clutch member.

2. The combination of a frame, a tank having guide rollers therein, winding rolls journaled on the frame above the tank, a drive-shaft, gears for transmitting rotary motion from the drive shaft to the said rolls, clutch mechanism on the drive shaft, means for shifting the clutch mechanism to cause motion to be transmitted to one roll or the other, a storage roll located above the drive shaft and parallel with the first-mentioned rolls, transmission means from the drive shaft to the axial center of the storage roll characterized by a shaft, gears, a pulley on said shaft and one loose on the drive shaft, a belt extending over said pulleys, the hub of the pulley on the drive-shaft having claw teeth to form a clutch member, a clutch member keyed to slide on the drive shaft, the members of said clutch mechanism having inwardly projecting claw-teeth, one surface of which teeth slopes in a direction which will cause them to push apart when the speed of the top roll due to its momentum exceeds the speed of the drive-shaft, whereby said roll will stop automatically without the attention of the operator, and means within the control of the operator for shifting the clutch member.
