APPARATUS FOR CHANGING THE POFITIONS OF HANKS 0F YARN ON DYEING-STICKS.

Specification of Letters Patent.

Patented June 20, 19148.

To all whom it may concern:

lie it known that I, Jacouns SorrLUMrr, a citizen of the Swiss Republic, residing at Brugg, Canton Aargau, Switzerland, have invented certain new and useful Improvements in Apparatus for Changing the Positions of Hanks ofYarn on Dyeing-Sticks, of which the following is a specification.

Yarn in 'hanks is dyed or bleached by suspending the hanks from sticks or rods which are laid across the dyeing tubs in such a manner that the hanks are partially immersed into the dye. To dye the hanks uniformly throughout, the position of the same upon the sticks is changed, from time to time, so that at each change of position, that part of the hanks. situated above the surface of the dye, is dipped into the dye.

The object of the present invention is to improve the machines which have been used hitherto to perform automatically the abovementioned operation of shifting the hanks of yarn. I attain this object by using a hank carrier consisting of two bars rigidly connected with each other and by rotating the carrier alternately about the two parts in such a manner, that the upper bar always turns around the lower bar. The hanks of yarn follow the descending bar by their own weight without stretching the threads in a dangerous manner.

To accomplish these objects, my invention consists in the novel details of construction and in the combination, connection and arrangement of parts hereinafter more fully described and pointed out in the claims.

In the accompanying drawings forming part of this specification wherein like numerals of reference indicate like parts: Figures 1 to 6 show a carrier for the hanks of yarn in several different positions. Fig. 7 is a sectional elevation of a machine for automatically turning the carriers. Fig. 8 is another sectional elevation of the same machine. Figs. 9 to 14 illustrate diagrammatically the difierent positions of the hank carrier and of the hooks for turning said hank carrier. Fig. 15 shows a modified construction of the machine in side elevation. Fig. 16 is a front view of the machine shown in Fig. 15. Fig. 17 is another form of construction in front view, parts being in section. Fig. 18 is a side view of the machine shown in Fig. 17. Fig. 19 is a side view of a stationary machine for turning the hanks. Fig. 20 illustrates this machine in front view, parts being in section and Figs. 21 to 23 illustrate a clutch. Fig. 24 shows a device for opening the lifters. Fig. 25 is a detail View showing a portion of Fig. 24.

The hanks a are arranged on a carrier 7) comprising two parallel bars 3 and 4: rigidly connected by two cross bars 1 and 2. One of the bars 3 is sufliciently longer than the other bar t so that the carrier 7) may be laid transversely across the trough containing the liquid for the treatment of the hanks a, while the other bar 1 is shorter so that it may be arranged between the side walls of the trough. The distance between the bars 3 and 41 is considerably less than the length of the hanks a. The operation for shifting the hanks a, if performed by hand, is the following: The bar 3 is raised from the trough by two operators standing on opposite sidcs of the trough and turn until the bar 4 is above the trough. The bar 4: is now held by the two operators while the bar 3 is released, and. together with the hanks desccnds into theposition shown in Fig. 3. During the descent of said bar 3, the threads of the hanks cannot entangle and they are not submitted to any stress or friction so that the threads will not be unduly stretched or torn. After having made one turn of 180 about the bar 4:, the carrier 7) is rotated for a second time by using bar 3 as the axis of rotation. That part of the hank which was previously resting on the bar 8 is now below the level of the liquid after the carrier I) has performed two turns. The carrier Z), which ultimately assumes the position shown in Fig. 5 is then laid on the trough. The carrier 7) may be constructed as shown in Fi 6. 4 arranged parallel to each other in the cross bars 1 and 2. On said cross bars 1 and 2 two studs 3 are fixed by means of which the carrier Z) may be laid over the trough. .By using the carrier 7) Fig. 6 the hanks a may be entirely immersed in the liquid.

The hank shifting machine illustrated in Figs. 7 and 8 comprises two frames fixed to a common casing C. Said casing C is suspended from two parallel shafts provided with running rollers at their ends. The running rollers are guided upon rails 6 and 7 which are fixed above the trough. For the purpose of taking hold of the hank carriers at their ends, there are pivotally mounted The hanks a are slid over two sticks 9 ill] 'grasp the upper bar 3 in each frame two lifting wheels with two lifters arranged diametrically opposite each other. Each lifter comprises two ro-- tatably mounted parts 12 and 12 which are held in normal position by a spring. The parts of the lifters may be forced back by means of guides 13 (Fig. 7) fixed on the said framesfor the purpose of permitting the ends of the carrier Z) to enter the lifters. The lifting wheels 10 are driven by a motor 1 1. The motor axleis geared to the lifting wheels 10 by means of a spur wheel keyed to a shaft 16 which is connected with a shaft 19 by means of a toothed gear 17. The said shaft 19 is rotatably mounted in the two frames of the machine and carries two spur wheels 18 which drive by means of an inter mediate wheel 11 the two pairs of lifting wheels 10 which are all rotated in the same direction.

If the gear 10 rotates fromthe position 2 shown in Fig. 2 1, the part astrikes against the guide 13 fixed to the frameof the ma chine at a point 0. One ofthe levers 12 having'anose at co-acting for lifting a stick 3 with a lever 12, is forced to swing out against the action of the spring (Z. The other lever 12, which does not have a nose at, rests immovably in relation to gear 10 but lifts the stick 3 from the trough. As soon as the stick 3 rests well within the lever 12, the lever 12 slides from the guide 13,

owing to the'tensio-n of the spring d. In the same mannerthe lever 12 is swung out in the top position shown in- Fig. 24: by means of a guide 2 1 fixed to the frame of the machine.-

As soon as a hank carrier 1) has been lifted off the edge of the trough by the lifter on the lifting wheels 10, two hooks 23 of the hank carrier near its end. The lifters are now automatically opened by means of cams 24. As soon as the carrier is held by the hooks 23 and the lifters have been opened, the lower bar 4 of the carrier 5 is caught by a pair ofhooks fixed on a shaft'26 (Fig. 3). The hooks 25 are supported by collars 26 and oscillated by the shafts 26 which are connected by the connecting link 31 with a crank pin on the shaft 19 (Fig. 7). The movement of the hooks 23 and 25 is such that the upper bar 3 is released by the hooks 23 as soon as the lower bar 4 is engaged by the hooks 25, so'that the carrier 5 makesa turn of about 180 about the bar 4:. The hooks 25 swinging in the direction of the arrow shown in Fig.13 raise the carrier Z), and the latter is laid upon two seats 32, provided at each side of the machine. (See 7 and 8.) To prevent the carrier from passing over the said seats 36 I arrange on each side of the trough a lever 27, pivotally mounted in the frame of the machine (Figs,

7 and 8). The carrier resting on the seats 36 is now lifted for a second time by means of the second pair of lifters on each wheel 10. The said second pair of lifters are automatically opened and move the lower bar 4, while the upper bar 3 rests on the seats 36, in a circular path without moving the carrier. The carrier is then laid transversely over the trough.

The rotation of the motoaxle is further transmitted by means of the gear 15, shaft 16 and toothed gearing 1S and 19 to a shaft 20. journaled in the side wall of the casing U. On each side of the casing (l a spur wheel 21 is keyed on shaft 20, said spur wheel 21 engaging a rack. 22 fixed to the rails 6 and 7. The direction of travel of the machine may be reversed by reversing the direction of rotation of the motor axle or by any well known change gear. There may be arranged two sets of hooks 23, 25, one set working while the machine travels in onedirection, while the other set works when the direction of travel is reversed. Moreover I may, provide means to bring the hooks out of action for instance by uncoupling the shafts 26 from the driving gear. A suitable clutch for this purpose is shown by way of example in Figs. 21 to 23. The connecting rod 31 is pivotally connected to a rocking lever 32 which is loosely mounted upon the shaft 26. Lever 32 is provided with an arm 34: which has an axially projecting arm The arm 35 projects into a recess 36 in an arm 33 keyed to said shaft 26. Between the rocking lever 32 and the lever 34 a pawl 37 is rotatably mounted. The said pawl 37 is provided with a lug 38 which together with the arm 35 completely fills the recess 36of the arm The pawl 37 is controlled by a weight which tends thrust the lug 33 into the recess 36. If the pawl 38 is not in the recess 36 the lever 32 can rock without taking the leyer 33 and the shaft 26 along.

The throwing into and out of operation of the pawl 33 and consequently the rocking of the hooks 23 and 25 is effected by a double-armed lever 41 (Fig. 7), pivotally mounted in the casing C. One end of the lever 4. 1 projects into the path of a lag -l-,() on the pawl 37 while the other end carries a roller running on a cam which is keyed on a. shaft. The said shaft is rotatably mounted in the casing and may be rotated by hand or automatically by means of suitable devices which come to action as soon as the machine changes its direction of travel.

The machine shown in Figs. 15 and 16 works in essentially the same manner as described with reference to the machine shown in Figs. 7 and S. It differs from the machine described above in that the machine is not suspended on rails but runs on rails fixed to the floor. The machine is double acting, and it is adapted to turn the hank carriers of two troughs standing parallel to the direction oftravel of the machine. The carriers Z) are held on one end only by means of lifters arranged on lifting wheels 613 of which two are provided for each trough. Each lifter comprises two parts 1t slidable on each other and actuated by double armed lever 46, in such amanner that the carriers are automatically grasped and released. The rocking motion of the hooks 23 and 25 is imparted by a system of lovers actuated by a cam. The functions of the hooks 23 and 25 are precisely the same as described above with reference to Figs. 9 and 12.

The machine shown in F 17 and 13 comprises a casing C suspended by means of two pairs of rollers 80, 81 running on rails 82. In the casing C an electric motor M is mounted and drives by means of two gears a shaft 85 ournaled in the side walls of the casing C. Exterior to the side walls of ms ing 0, the shaft 85 is provided with two spur wheels 87 engaging racks 89 fixed to the rails 82. The gearing comprises a clutch 90 and a shaft 91 which project on both sides from the casing (1. Near each of the ends of shaft 91, outside the casing C, a spur wheel 93, and a disk 94 are secured. The said spur wheels 93 drive the lifting wheels 95 by any well known means (not shown). The lifting wheels 95 are rotatably mounted in frames 90 secured to the casing C. Each of the lifting wheels 95 carries a lifting ring 97 having at its cir cumference teeth 98 at regular distances apart from each other. The arrangen'ient of the lifting gear is such that the teeth 93 lift the carrier 7) off the edge of the trough T. Above the lifting wheels 95 there is 1'0- tatably mounted in bearings a shaft 100 which receives a rocking motion from a crank pin on the said disk 9&1 by means of connecting rods 101 and levers 102. A clutch, similar to that shown in Figs. 21 to 23, and described with reference thereto, may be arranged on said shaft 100. The shaft 100 is connected with a shaft 100 by means of a lever 107. To shaft 100 two hooks are keyed adapted to hold the carriers 7). Parallel to the shaft 106 there is arranged another rocking shaft 100 on which a pair of hooks 110 is secured. Shaft 106 receives its rocking motion from the shaft 100 by means of a system of levers not shown in the drawings. Below the hooks 110, 110' and above the lifting wheels 97 two oscillating arms 111 are keyed to a shaft 112 mounted in bearings of the frame 96. Each oscillating arm 111 is provided on its free end with a guide piece 113 by means of which the carrier 7) may be lifted off the lifting rings 97. The oscillating arm 111 is raised by a lever 115 which is pivoted at 116 and which is raised by means of a cam 117 secured to the shaft 91. Lever 115 is provided at its free end with a stud with which one of two upright hooks 118 may come into engagement. The said hooks 118 are steered by lever 119 from the shafts 100 in such a manner that the oscillating arms work in conjunction either with the shaft 100 or with the shaft 106. The movements of the parts 110 and 113 are such that the oscillating arms 111 lift a carrier 6 from the lifting ring as soon as the hook 110 has descended into its lowest position and pass behind the carrier 6 and immediately before the hook 110 reverses its action. The hooks 110 catch on the upward movement the lower bar 1; of the hand carrier 1) and as soon as it held firmly the upper bar 4: falls down, the carrier Z) making a turn of 130 about the lower bar 1. The latter is now deposited on two movable seats 11S arranged at the sides of of the lifting rings 97. The bar 4 is now liberated by the said hooks 110 and the car rier t performs a second turn of 180 about the bar 3. The carrier 7) falls from the seats 118 by its own weight and is deposited upon the edge of the trough. While the machine is traveling in one direction the hooks 110 are in operation while by reversing the direction of travel the other pair of hooks 110 come to action. Of course both pairs of hooks can be brought out of action.

In some instances it is desirable to lift all the carriers 7) together from the edge of the trough. To achieve this result I employ a lifting appliance comprising two pairs of carriages 120 arranged on both sides of the trough. These carriages are guided on vertical. rails 121 secured to the casing C. The carriages on one side of the trough are adapted to carry a bar 122 which when rising lifts the carrier 7). To raise the carriage 120 and the bars 122 I make use of the motor M which drives the shafts 125 by the intermediary of a toothed gearing. To said shaft 1.25 two drums 127 are secured to which ropes 130 are attached. These ropes 130 are guided over guide pulleys 120 and the ends of the ropes 130 are secured to the bars 122. The lifting appliance comprises a brake 131, and a device for disconnecting the lifting appliance from the rotor M of known design, but not illustrated.

In Figs. 19 and 20 a stationary machine is shown diagrammatically. The trough T is mounted upon a carrier running on rails 130. On both sides of the trough T frames 137 are secured to bases 138. The two frames 137 support a driving shaft 139, and two spur wheels 141, 1412 loosely mounted, either of which may be connected with the shaft 139 by means of a clutch 143 axially movable but not rotatably mounted on the shaft 139. The spur wheel 1 11 is in mesh with a wheel 14: 1 on a shaft 145 and the spur wheel 1412 engages a transport wheel 147 meshing with a gear 1 16 keyed 25 oawl en 'a in a toothed ear on shaft 153.

12 b b b to said shaft 145. The direction of rotation hooks 154 adapted to turn the carrier 7) in the manner described above. The shafts 153 have a rocking motion which is imparted to them by connecting rods 155 from the gear'151. Upon the shafts 153 clutches are arranged by means of which said shafts may be thrown out of connection with the driving gear 151. Special means are shown for. the purpose of bringing the hooks 154,

which are not to work, to a standstill. On each side of thetroughftlwre is arranged a horizontal bar 160 which is mounted on two levers 161, 162. To the bar 160 a cam plate 163 is secured which acts upon a double arm lever 166. The latter is provided with a If the bar 160 is moved to the left in Fig. 19 the lever 166 will move the said toothed wheel on shaft 153 for one tooth and hold the shaft in a fixed position whereby the hooks 154 are out of way. The bar 160 is automatically shifted upon each reversal of the direction of travel of the machine. The lever 162 is abell-crank lever, one arm of which is connected bya rod 168 to an arm 169 of a shaft 170 which operate the clutch 143 by means of bevel gears.

' The carriers Z) are lifted by the wheels150 and then turned by the hooks 154 which get hold of the lower bar of the carrier laid on the lifting wheel. After the carrier has been turned 180 the bar 4 ofthe carrier is laid on the said bars 160. The hooks 154 rceede and the carrier Z) will fall down making another turn of 180 whereafter the carrier is deposited upon the edge of the trough. The carriage 135 may be provided with a rack and a train of spur wheels may be arranged in one of the frames adapted to engage said rack.

I do not limit my invention to the means for lifting the carriers or the driving gears for the different organs in the machine, but

What I claim is:

1. A machine for automatically shifting hanks of yarn comprising in combination a trough, carriers having two pivots, means to lift said carriers separately, and means to turn the said carriers about the lower pivots.

2. A machine for automatically shifting hanks of yarn comprising in combination a trough, carriers for the hanks comprising two parallel rods connected with each other, two pivots on said carrier, rotating lifting Wheels, hooks adapted to engage the lower pivots of said carriers, and means to change the relative position of lifting wheel and trough.

3. A machine for automatically shifting hanks of yarn comprising in combination a fixed trough, carriers comprising two parallel rods, connected with mch other, rotating lifting wheels one on each side of the trough, swinging hooks, means to lift the carriers from the lifting wheel into the path ofthe hooks, and means to move the machine relatively to the trough.

In testimony whereof I a'liix my signature in presence of two witnesses.
