Application led March 9, 1916. Serial No. 83,007.

To all whom t may concern:

Be it known that I, WILLIAM J. GOING, a citizen of the United States, residing at Amsterdam, in the county of Montgomery and State of New York, have invented certain new and useful Improvements in Yarn- Treating Machines, of which the following is a full, clear, and eXact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to yarn treating apparatus, and particularly to apparatus for '-.vashing, scouring and dyeing yarn.

One of the objects of the invention is to provide a practical and efficient machine of the character referred to. Another object cf the invention is to provide a simple construction of machine wherewith long delays, due to possible abnormal operation, as by misplacement of the yarn, are avoided. Another object of the invention is the provision of a practical machine wherewith breakage of the machine and of the yarn and soiling of the latter are largely avoided.

' Other objects will be in part obvious and in part pointed out hereinafter.

' The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

-lfn the accompanying drawings forming part of this specification, and wherein similar reference characters refer to similar parts throughout the several views,.

Figure 1 is a front elevation of a machine of the character described for scouring yarn;

Fig. 2 is a rear elevation of the machine shown in Fig. 1 and showing also a portion of another similar machine at the left-hand side;

Fig. 3 is a detail perspective view of the form of shift mechanism employed in Figs. 1 and 2;

Fig. 4 is a front view of a portion of Fig. 1, illustrating a modified form Y of shift mechanism associated therewith;

' Fig. 5 is a rear view of the machine shown i Fig. 6 is an end view of the shift,v mechaclosed as embodied in a machine similar to that forming the `subject-matter of applicants companion application filed March 11, 1915, No. 13,596 (1915), tho-ughvit is to be noted thatthe inventionl is capable of being differently embodied without departing from the spirit thereof. 1 is the frame of the scouring machine, the various shapes of portions of which will be best understood from the drawings, and which may be `varied indefinitely in shape according to the detail of the remainder of the apparatus.' 2 an electric motor driving the apparatus through a gear 3. 'A second gear 4 is mounted on a countershaft v5, as is also a gear 6. The main shaft of the machine is numbered 7 and is Ydriven by a gear 8, meshing with the gear 6 through the collar of la clutch 9. A worm 10 drives the worm wheel 11 on the shaft 12, presently to be referred to, and a gear.13, through another gear 14 on the shaft 15 and worm 16 upon that shaft, drives a worm gear 17 turning the shaft 18. On the right-hand end of the shaft 7 (Fig. l) is loosely journaled a bevel gear 19 driving another bevel gear 20, presently to be further described; a clutch 21, the collar 22 of which is fastened to the shaft, connects the gear 19 thereto or throws it out, as may be desired.

Turning now to Fig. 2 in connection ywith Fig. 1, it will be seen that the apparatus is located in a tank 23, and in part consists of a conveyer for the material to be treated, l

this .conveyer comprising two aprons, marked 24 and 25. rlhe construction of these aprons may be similar to that set forth in the prior application above referred to,

rand reference thereto maybe had for a fuller description. It is suflicient to here state that the aprons 24 and 25 have a circuitous course in the liquor in the tank 23, and that the yarn is carried by and between these aprons into, through and out of the liquor. i;

The yarn passes into the machine from thel tablev `26 on one side {of the machine andl 30 of the upper part of the machine frame register' with the outside of the tank or vat 31 of a Isecond machine. From the shaft 18 of the lower roller 2S, by means of a sprocket, is driven a transfer roller 33 carrying the yarn to the apron 34 of a second machine similar to the first. The yarn be ing brought up from the rst tank on the apron is transmitted to the squeezing rolls, and is then carried to the transfer roll 33, which in turn drops it upon the apron 34 of the succeeding machine.

` As these machines are driven by power and the load upon them varies considerably,

an ample surplus of power must be .provided; and as the squeezing rolls are under Vvery heavy pressure, any operation about the machines is dangerous unless abundant facilities for stopping them quickly be provided. YThis has been arranged in the ap.- para'tus herein illustra-ted. Referring to Figs. 1, 2 and 3, one form of stopping system is illustrated. The lever, or member, 35. is an ordinary shifting lever working through the link 36, the lever 37, pivoted at 38 and operating the collar of the clutch 9, connecting the gear 8 to the shaft 7. A

spring 39 of ample power to throw the lever is connected to the link 36 and as a factor of safety another spring 40 is also provided, so that when the lever 35 is released, it will certainly be operated. The lever 35 l is held in place hy a rotary dog, as a cam 41 formed upon a gear 42. A notch behind the cam holds the lever 35 in place, but when the gear 42 is revolved by moving the handle 43, the inclined surface of the cam is presented to the lever 35; the springs 39, 40 pull over the lever 35 and shift the clutch 9, bringing the machine to an instantaneous stop, inasmuch as the worm gears 10, 16 serve as effective brakes. At 44 is an abutment, or board, mounted rigidly upon a shaft 45; connected to the shaft at each end is a bell crank lever 46. On one side of the machine is a bar 47, connected at one end to the lever 43 and sliding in a guide 48, a stop 49 limiting its movement. One. of the bell crank levers 46 connects with this bar at a slotted end 50. If the hand or the yarn is thrust againstfthe board 44 with sufficient "force, the lever 46 will, by the rotation of the shaft 45,- be thrown to lright Fig. 1, throwing w-itlritthe bar 47 and thus operating the lever 43, turning the cam 41 so as to release the lever 35, and throwing out the main clutch 9 of the machine. On the other side of the machine the corresponding'bell crank lever 46 is connected to a sliding bar 51, to which are also connected the handles 52, 53, the latter working against a spring 54. At the lefthand end of the bar 51 (see Fig. 2) is a lever 55 and an abutment, or board, 56, is connectedto the shaft to which this lever is keyed. This board, as will be observed, is in front of the rollers 23, 29, which squeeze the yarn, and it will be obvious from the connections that if this board be pressed toward the "rolls, it will throw the bar 51 to the left and operate the bell crank lever 46 and bar 47, thus, as already explained, throwing out the main clutch of the maf chine.

The construction hereinbefore described is similar to that of the prior application above mentioned, andis appended with the view of enabling one to herein clearly understand the general construction and operation of the machine, and particularly the construction and operation of the stopping mechanism and its relation to the other functions of the prior machine. 1t will be observed that, in order to stop the machine bythe construction hereinbefore described, the cam 41 has to be turned, and that the turning of this cam is accomplished by a movement of the rod 47, in consequence of which the boards 44 and 56 are likewise turned.

lWhen the machine is running, it may be desired to stop it without disturbing the boards 44 and 56, and to this end the construction illustrated in Figs. 4, 5 and 6 has been devised, in which, nevertheless, the features of stopping by proper movement of the boards or abutments 44 and 56 are maintained. Referring now more particularly to Figs. 4, 5 and 6, the numeral 56 indicates the board or abutment in front of the squeezing rolls and 55 indicates the bell crank lever or dependingarm which is moved by said abutment, as hereinbefore described. Applicant has chosen to explain the different form of shift or stop mechanism in connection with the board or abutment for the squeezing' rolls, but it will be obvious that its construction and operation are as well applicable to the board adjacent the feed table 26, and in divers other places. rlhe abutment lies in front of the squeeze rolls 28 and 29 with its lower edge spaced from the adjacent apron a sufiicient distance to permit the passa-ge of yarn of normal depth to said rolls. The abutment 56 extends the full width of the aprons and should the yarn be Ahunched ormassed so as to increase in thickness at any point in its width it will be forced against. the abutment by the movement of the conveyor aprons and will turn the abutment on its axis. The 'lower end of arm 55 is in coperative relation with a rod 57, disposed longitudinally of the tank e 23 and guided in keepers 58 on one side of the tank. Vhen an abnormal operation of the machine occurs, as by reason of the bunching of the yarn hereinbefore referred to, the present invention provides for automatically cutting out the driving relation between the driving and driven elements, and this cutting out is referred to herein by the term disengaging or the like, as being a simple term to indicate the function accomplished. This term is, of course, intended to include any of the many ways in which a machine is directly connected and disconnected from its power, as by clutches, belt-pulleys, etc. l p

The numeral 59 indicates a manually operative member, or shift lever, connected by a link 60 with the lever 37 fulcrumed on the side of the tank and connected to the rotatable driving clutch or element 9 which rotates with the shaft 7. By shifting the lever 59 the driving clutch 9 may be engaged and disengaged with the driven gear 8 and thus power applied and eut off from the conveyer aprons. The lever l59 is fulcrumed on the side of the vat in any suitable way, as by being pivoted in the strengthening brackets 61 fastened to t-he vat. The numeral 62 indicates a movable device 'or member, which, in its specic aspect, is aV motor-device and comprises an upstanding arm pivoted on the same axis` as is the lever 59 and having a handle 62 and a lower horizontally disposed arm 63 on which is aY weight 64 adjustable on arm 63, the weight tending to move the device 62 in the direction indicated by thearrow A. The device 62 is herein termed a motor-device, inasmuch as it automatically moves in a predetermined manner under the influence of the weight 64 when it is free to move, and energizes other parts. The motor-device is adapted, when moved in a predetermined direction, to move the lever 59 in a direction to cause disengagement of the driving and driven clements hereinbefore referred to, so as to cut on the apparatus from its power, and in the present embodiment is provided with a projcctiorn'a square lug 65, which engages the edge of the lever 59 and shifts said lever. When the shift lever 59 is in such position that the drivin g and driven elements areengaged, the motordeviceV 62 is held in such position as not to energize the shift lever 59 by means of a stop-dog 66 which is adapted to be moved into and out of engagement with the motor-device. ln the present embodiment the dog 66 is rotatable into and out of position in the path of the motordevice and is comprised in a semi-circular gear 67, the flat face 68 of which may be disposed across the path of the motor-device or outside of said path. `AThis dog is rotatably of the shaft being provided with a triparm 71 fastened thereto so as to rotate therewith and with the rotatable dog 66. The

i elements just referred to are so relatively arranged that when the motor-device 62 is drawn back into the position from which it moves to cause disengagement of the driving and driven elements, the dog -66 may stand opposite the edge of the element 62 so as to stop disengaging movement of said element, and at this time the trip-arm 71 will be in a horizontal position. This latter arm is held in such horizontal position by means of a trip 72 carried yby an arm or lever 73, one end of which is pivoted to a iiXed bracket 74, and the other end of which is slotted for engagement of a pin 7 5 carried by therod 57. The rod 57 is strained in a direction to place the trip 72 beneath the trip-arm 71 by means of a spring 76. The trip 72 is pivotally connectedl to the lever 73 so that it may beV rotated upwardly to escape the end of the trip-arm 71 at certain times, its lowermost position being determined by a stop 77 on lever 73. On the shaft is a rotatable sleeve 78, having at one end a trip-arm setter, comprising an arm 79 rotatable with said sleeve and disposed opposite the trip-arm 71, the sleeve 78 being provided with a handle 80 for conveniently rotating the same. The depending arm 55 may pass through a slot in the rod'57 or may abut against a pin .81 on said rod, as illustrated. y

The operation of the machine in conjunction with the form of shift or stop illustrated in Figs. d, 5, and 6 will be apparent from the foregoing description, but may be briefly described as follows: When the yarn becomes so hunched as to move the abutment 56, the arm 55 will move the rod 57 against the resistance of the spring 76 and will cause the lever 73 to rotate, thus drawing the trip 72 from beneath the triparm 71 so that the latter will be free to rotate. The weight 6d will then cause the motor-device or arm 62 to advance in the di- -rection to cause the lug 65 to engage the drawn back. The sleeve shaft 7 8 is then'rotated-by means ofthe handle y8,0 in the direcaen wthatthe trip. setting. arm 79,Will

rise and lri'ft the trip-arm 71 and sweep the same pasty the endot the trip 72, the latter rotate, causing the gears on the dog and shaft to set thev dog into stop position relative to the device 62. The trip-arm 72 will descend to its position limi-ted by the stop 77, and the trip-arm 71 will rest thereon and hold the dog 66 against the pressure of the device 62. lt will be observed that the tripP lever 59 may be operated freely sol as to cut in and cut out the power irrespective of the movements of' the device 62. Preferably when the device is set in position with the driving and driven elements engaged, the Vtrip lever is lockedL in its position by means of a paw-l, or coupling, 81 pivoted thereto and engaging the lug` G5, this pawl having a handle 82 alongside the handle of lever 5-9. The lever 59, at its upper part, is guided in a slotted bracket 83 secured to the tank wall.,

Fig. 7 illustrates the invention embodied in a form of dyeing machine having a conveyer comprising a rotatable reel carrying rotatable yarn sticks, each stick having a star wheel adapted to cooperate with a device to eiiect turning ofl the sticks in one direction on their axes during operation of the dyeing machine. Turning of the sticks in the opposite direction is restrained by the customary ratchets. rEhe reel is indicated at 100, and the sticks 101 are provided with star wheels 102 and pawls 102. They are shown inside the tank or casing 103, the star wheels coperating at the top of the tank with a lstick-turningdevice comprising a pivoted arm or abutment 104: on the inside of the tank having an arm 104 iiXed to the pivot 105 at the outside of the tank. rllhe reel normally rotates in the direction of the arrow B. Should any yarn stick be prevented from rotating on its mounting in the reel, the arm 104C will be pressed and rotated on its axis in the direction indicated by arrow C. 106 is a weighted lever pivoted at 107, one of its arms 108 being in the path of a pawl 109 pivoted on arm 104, this pawl being held to rotate with arm 101 in the direction of arrow C. The other or depending arm of lever 106 is linked to a lever 110 pivoted on the frame at 111, one end of this lever cooperating with the pin 81 to move the rod 57 against the resistance of the spring 76 to remove the trip 72 from beneath the trip-arm 71 and permit the dog 66 to rotate out of the way of the motor-device 62. The stop or shifting device illustrated in Fig. 7 is the same as that shown in Figs. 4, 5 and 6, except that all its parts are on the same side of the tank. v

y For discharging the contents ofthe tanks when desired,a valve, as illustrated in` Fig. 1, may be employed. The numeral l2()v in- ,s nasasea dicates a valve casing communicating with the tank,y the valve being indicated at 121 and its seat at 122 opposite the outlet. A foot lever 123 is fulcrumed on the valve casing, onev arm of this lever having a pedal piece 124 and the other arm having a pin and slot connection with the stem 125 of the valve. Pivotal-ly connected to the foot lever- 123 is a pawl 126, the notch 127 of which is adapted to engage a stationary member 128 to hold the valve in open position, a spring 129 being connected to the pawl and the member 128, so that its stress tends to urge the pawl notch against the member 128,v and also tends tol close the valve and hold it closed when the pawl is released for interlocking engagement with the member 128. The pawl 126 has a pedal piece 130, depression of which lifts the notch of the pawl out of locking engagement with member 128, permitting the spring 129 to, close the valve.

As many changes could be made in the above construction and many apparently widely different embodiments of this'invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanyingl drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the language used in the following claims is intended to cover all of the generic and speciic features of the invention herein described and all statements of the scope of the invention, which, as a matter of language, might be said to fall therebetween.
