DRIVE MECHANISM FOR DYEING MACHINES.

Application filed April 19, 1922. Serial No. 555,565.

To all whom it may concern:

Be it known that we, JoHN H. Guns and DONALD M. Gross, both residing at Philadelphia, county of Philadelphia and State '5 of Pennsylvania, have invented certain new and useful Improvements in a Drive Mechanism for Dyeing Machines, of which the following is a specification.

This invention relates to dyeing. machines in which yarn in skeins is immersed in a dye liquor. In such machines it is customary to provide a dye vatand a reel, or other. device of that character, upon which the skeined yarn maybe mounted. The reel is supported so that it may be raised or lowered relative to the dye vat, and when in the lowered position, the lower yarn supporting sticks are below the surface of the liquid. Upon revolving the reel the skeins of yarn are immersed in the dye, and suitable provision is made ordinarily so that all parts of the skein may be subjected to the dyeing action. In devices as thus briefly described, driving mechanism is provided by which the reel may be rotated and it is herein contemplated to provide a new and improved driving mechanism together with means by which the source of power for rotating the wheel may be also utilized to lift the reel clearof the vat.

One of the objects of the invention, therefore, is to provide a new and improved driving mechanism for dyeing machines of the class described, in which means is provided by which the yarn reel'may be raised out of'the' dye vat while being continuously rotated. Q

Another object of the invention is to provide anew and improved driving mechanism for dyeing machines of the class described, in which the means for revolving the reel may be utilized for raising or lowering the yarn supporting structure relative to the 'dye vat, provision being made for revolving the reel in either direction of rotation, and at different speeds and the elevating mechanism being operable regardless of such direction.

Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious and inpart pointed out in the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; [and tail of the clutch for thescope, of protection contemplated will be indicated in the appended. claims.

In the accompanying drawings, in which there is shown a preferred form of embodiment of our invention:

Figure 1 shows an end view of the dyeing machine provided with our new and 1mproved driving mechanism.

Figure 2 is a side new of the same with part of the enclosing structure removed.

Figure 3 is a detail view with parts broken away of a driving speed changing, and reversing mechanism. Y i

Figure 4 is a detail view onthe line 4.-4 I

of Figure 3, showing the. various parts used for reversing purposes. I

Figure 5 is a cross-sectional view of a de the elevating mechanism; and

Figure 6 1s a viewin detail, showing the worm drive for the elevating mechanism.

1W1th reference now to the drawingain which similar reference characters designate 'similarparts throughout the various views thereof, 1 designates a dyeing machine having upright supporting members 2, and enclosing plates 3; Mounted on one end of the dyeingmachine is the driving mechanism 4-. therefor, supported by a suitable bracket'5.

The-driving mechanism is provided. with a 1 pulley 6 mounted in a projecting bracket 7, the pulley 6 being driven from any suitable source of power. Referring now to Figure 3, it will be seen that the pulley 6 ismounted on the shaft 8, supported in suitable ball-bearings 9 in a case 10. At one end of the shaft 8 there is provided a gear 11, onthe inner face of which is mounted a clutch aw 11". .The gear 11 mesh'es with a corresponding gear mounted on the shaft 13, which'is also provided with gears 14 and 15 rigidly secured. thereto. The gear 14 meshes with a small pinion 16mounted on the stud 17 in the casing 10 as best shown in Fig. 4c, pinion 16 in turn meshing with 'a gear 18, which is slidable along a shaft 19, but keyed thereto as indicated at 20. On the inner face of the gear 18 it is provided with a clutch jaw 18.

It will be seen that the shaft 19 is mounted transmission as used in motorlvehicles, and

I vanced position.

it will be seen that in the form of transmission herein shown, it is possible to secure a reverse drive for the shaft 19 by means of causing the gear 18 to mesh with pinion 16 and therethrough to be driven by the gear 14, or to secure a direct drive of the shaft 19 by moving the gear 18 along the shaft until it meshes with the gear 15. By moving the gear 18 further along the shaft until the clutch jaw 18 meshes with the jaw 11, the shaft 19 will be directly driven from the shaft 8, that is to say, there will be no reduction in speed between shaft 8 and shaft 19.- Bf," moving the gear 13 to the point in between the: gears 14 and 15, it is possible to stop the rotation of shaft 19, and the structure mounted thereupon, as will be later described, while at the same time permitting shaft 8 to be continuously driven.

. In order 'to secure the speed changes by causing the gear 18 to mesh with different gears on the shaft 13, there is provided in case 10 a stud 22,having keyed thereto an arm 23, having a fork 24 in its extremity, which engages in a groove 25 cut in the hub of gear 18. The stud 22 is provided with linkage, as indicated at 26, 27 and 28, which is in turn connected by means of a rod 29 to a handle 30 on the front of the machine. By moving the handle 30 it will be seen that the fork 24 will be rocked so as to move the gear 18 from its position as shown in Figure 3, to the point where it willmesh with the gear 15, or until the clutch jaw on the gear will engage with the jaw on the gear 11.

Shaft 19, as indicated in Figure 2, extends from one side to the other of the machine, and is provided with a coupling 31, by which it is connected to another shaft 32. Shaft 32 passes through a case 33 and slidably mounted on the shaft 32 is one of a pair of clutch jaws 34, the aw 34 being keyed to shaft 32 and revolvable therewith. Corresponding to the jaw 34 is a similar jaw mounted on a sleeve 36 on which is. keyed a bevel pinion 37 within the case 33. The

pinion 3'7 meshes with a corresponding pinion 38, which drives the shaft 39, the lower end of the shaft 39 being provided with a worm 40, which meshes with a worm wheel 41 mounted on a shaft 42. The jaw 34 is provided with a groove 43 in which engages a fork 44, operable by means of a rod 45, a bell-crank 46, a rod 46 and a handle 46 mounted on the front of the machine, the bell-crank being provided, as is obvious, so as to change the direction of movement of the handle. The rod 46' is suitably pro vided with a spring 46? so that when the handle is operated, pressure must be maintained upon it, in order that the fork 44 will continue to hold the jaw in its, ad-

When the handle 46 is operated, the linked parts will force the jaw riphery of one of these heads being provided with teeth which mesh with a pinion 53, mounted on the shaft 49.

It will be seen then that as the pulley 6 is rotated, it communicates mot-ion in one direction or the other through the gear-shift to the shaft 19, which in. turn.- drives the shaft 49 and causes the reel to be revolved. The

reel 51 is provided with yarn supporting sticks running between the heads in the usual manner, the skeined yarns being supported on these sticks.

As indicated in Figure 2, the reel 51 is in the lowered position in which the lowermost sets of sticks on the reel will pass upon a revolution of the wheel below the surface of the dye liquor, which is contained in a suitable vat in the lower part of the dyeing machine. The heads 5252 are suitably supported on a shaft 54, which run in bearings mounted in the ends of arms 55, these arms being supported at their other ends on the shaft 49, as shown in Figure 1.

The bearings for shaft 54 are. movable in arcuate slots 56in the end enclosing plates 3 for the dyeing machine, and when the arms are raised in a manner to be described, the shaft 54 with the yarn support ing reel will be elevated to a position so that the lower sticks of the reel are clear of the dye liquid. The means for elevating the reel consists of the parts'as follows: The arms 55 have pivoted near their middle points links 57 which are in turn mounted at their other ends on eccentric pins 58 mounted in gear wheels 59, the gear wheels being supported on suitable studs in the frame of the dyeing machine, and meshing with pinions 60 mounted rigidlyon the ends of shaft 42. When the clutch aws 34 and 35 are engaged, the shaft 39 will be. rotated and this will in turn cause rotation of the gear wheels 59;. This in turn causes the links 57 to be raised, carrying the arms 55 and shaft 54 therewith.

By reason of the fact that the shaft 55 is moved in an are about the shaft 49, as a centre, the teeth on the head 52 will continue 111 mesh wit-h the pinion 53, so that the reel regardless; of the direction of rotation of the reel.

Inasmuch as it is a matter of indifference as to which direction the shaft 59 rotates in throwing the link 57, if by any chance the clutch should not be disengaged when the reel has reached the end of its upward travel, no damage will result, inasmuch as the continued revolution of the gear 59 will draw the crank downwardly, and thereby lower the reel to its operative position, as shown in Figure 1. As a further safeguard, as has been explained, the clutch control rod 46* is provided with the disengaging spring 46, so that whenever the handle 4:6" is released, the rod 46 will be moved so as to disengage the clutch, and thereby stop the movement of the hoisting mechanism.

In order to assist the movement of the reel, there are provided suitable counterweights 61, mounted on pulleys 62 on shafts 63, journalled in the top frame of the dyeing machine, the shaft 63 being connected by a suitable cord 64 with the bearings on the ends of shaft 54.

It will accordingly be seen that we have provided a simple, effective driving mechanism for a dyeing machine, well adapted to produce the desired results and one which will withstand rough and careless usage. In elevating the reel no damage can possibly result if the clutch is not disengaged at the end of the upward or downward movement of the reel, and it is, therefore,.not necessary to provide automatic stops, or other devices of that character, by which to limit the vertical travel of the reel. The reel may be rotated in either direction, as convenient, and the elevating mechanism is effective either way.

The gear-shift and clutch mechanism are suitably enclosed so as to be protected. and in turn to protect the operator. While specific arrangements as to the gear-shift, clutch and driving mechanism have been indicated, it will be understood that various modified arrangements can be substituted therefor within the scope of the invention, provided such arrangements will permit the continued rotation of the reel in either direction during its elevation and lowering.
