3 Claims.

, 1 I a My invention relates to drives and more particularly to drives for dye jiggers and the like, some examples of prior art jiggers being disclosed in U. S. Patents Nos. 1,780,628; 1,958,676; 1,994,545 and 1,996,815.

One of the objects of my invention is to provide a drive for a dye jigger or the like and which is soconstructed and arranged as to eifect either tension or tensionless operation of the jigger, as desired. I

An important object of my invention is to provide a drive of the foregoing described character which is capable of being applied to jiggers already in use without substantial modification thereof.

Another important object of my invention is to provide a drive for a dye jigger or the like which is simple in construction, durable in use, efficient in operation and economical in manufacture.

With the above and other objects in view, as will hereinafter appear, the invention consists in the combination and arrangement of parts hereinafter set forth and illustrated in the accompanying drawings from which the several features of the invention and the advantages attained thereby will be readily understood by those skilled in the art.

Referring to the drawings wherein like reference characters designate like parts throughout the several views:

Figure 1 is a top plan view of a dye jigger, part- 1y broken away, equipped with my invention.

Figures 2 and 3 are sectional views taken on the lines 22 and 3-3, respectively, of Figure 1. A Figure 4 is a detail sectional view taken on the the line 4-4 of Figure 1.

In practicing my invention, as illustrated in the drawings, I provide a dye jigger equipped with the usual tank 5 for containing a dyeing solution or bath and which is mounted within a base structure 6. The'tank is provided with brackets 1 which support a bearing frame 8 above the tank. The frame has journaled therein coincident end sections of the shafts 9 and ill of demountable rolls or beams l l and I2, respectively, disposed over the tank and about which a web of cloth W or the like is wound. The tank 5 is provided with a plurality of guide rollers 13 for guiding the cloth, as it passes from one beam to another, through the bath as is the customary operation-in dye jiggers.

The shafts 5 and ii) are provided with clutches l4 and l5,,respectively, each having a clutch ele: ment [6 slidably keyed to "the; respective shaft for operation into and out of operative engagement with a clutch element I! rotatably mounted on the shaft and with the clutch element [1 being provided with a sprocket {8 over which is trained a sprocket chain 19 for a purpose hereinafter made apparent. The clutch elements are slidably operated on the shafts by the usual forks 2! which in turn are operated by arms 2!, the latter being connected for unitary operation with a manually operated rod 22. The opposite end sections of the shafts 9 and 10 are each provided with the usual tension device 23 comprising a drum fixed to the shaft and about which drum is disposed an adjustable band carried by the frame whereby a desired tension or drag may be applied to the beams for effecting tension operation of the jigger.

The frame 8 has journaled therein, between the shafts 3 and I U, a power shaft 24 having fixed thereto a sprocket 25 which is connected by means of a chain 25 to a similar sprocket fixed to the drive shaft 27 of an electric motor 28, the latter being of the reversible type. The shaft 24 has mounted thereon a pair of spaced

clutches

29 and 30, respectively. Each clutch comprises a' clutch element 3| slidably keyed to the shaft 24 and a coacting element 32 rotatably mounted with respect to the shaft 24, the elements being provided with teeth for engagement with each other to effect unitary operation of the elements.

The elements 32 are mounted upon and in fixed relation with the hubs 32a of a pair of spaced: bevel gears 32b of a difierential unit 33. The gears 3% are loosely mounted upon the shaft 24 and are disposed within the sectional housing 34 of the unit, the housing 34 being mounted for rotation upon the hubs 32a of the gears 32b.

Disposed Within the housing 34 are bevel gears Memeshing with the gears 32a and each fixed to a stub shaft 36b having its inner end journaled in a bearing 34c keyed to the shaft 24 for rotation therewith-and its outer end journaled within :the housing 34. Inasmuch as the differentiali unit 33 is of an ordinary construction and forms no part of the present invention per se, a more detailed disclosure thereof is not deemed necessary. The elements 32 of the clutches 29 and have fixed thereto sprockets 35 about which is trained the chains l9, respectively. The ele-' ments 3! are operated into and out of engagement with the elements 32 by clutch forks 3! with the latter being actuated by arms 38.

In use, when it'is desired to operate the apparatus as a tension jigger and to wind the cloth about thebeam l2 from the beam H, the't'en sion device 23 on the shaft I is released to permit free rotation of the beam 12 while the tension device 23 of the shaft 9 is adjusted to effect rotation of the beam II under a desired tension or drag. When the devices 23 have thus been adjusted with the elements of the clutch I4 disengaged, the motor 28 is energized and effects clockwise rotation of the shafts I9 and 24 by reason of the respective elements of the clutches I5, 29 and 39 being engaged, the element I7 of the clutch I4 idling on the shaft 9. Rotation of the shaft It serves to wind the cloth about the beam I2 and to unwind the cloth from the beam I I. As the cloth passes from one beam to another, it is guided through the bath by reason of the guide rollers I3. By virtue of the drag applied to the beam II by the tension device, overrunning of the beam I I is not only prevented but a desired tension applied to the cloth, it being understood that the unit 33 is driven with the shaft 24. By adjusting the devices in a reverse manner, disengaging clutch I5, engaging clutches I4, 29 and 3G and operating the motor in the opposite rotary direction, cloth may be transferred from the beam I2 to the beam I I.

In instances where it is desired to utilize the jigger in the dyeing of cloth by the tensionless method, the clutches 29 and 3e are disengaged while the clutches I4 and I5 are disposed in engagement and the motor is operated in a desired direction to effect travel of the cloth from one beam to another through the bath, it being understood that the tension devices are released to preclude drag on the beams and that the rod or bar 22 is disengaged from the arms 2| to permit simultaneous engagement of the clutches I4 and I5. When the drive is thus operated, the differential unit 33 functions to effect rotation of both beams at coordinated speeds to permit the build-up of the cloth on one beam without tension being exerted thereon by the other beam.

Without further elaboration, the foregoing will so fully explain the invention that others may, by applying current knowledge, readily adapt the same for use under various conditions of service. Moreover, it is not indispensable that all the features of the invention be used conjointly since they may be employed advantageously in various combinations and subcombinations.

It is obvious that the invention is not confined solely to the use herein disclosed in connection therewith as it may be utilized for any purpose to which it is adaptable. It is therefore to be understood that the invention is not limited to the specific-construction as illustrated and described, as the same is only illustrative of the principles involved which are capable of extended application in various forms, and the invention comprehends all construction within the scope of the appended claims.
