IACHINE FR TRETNG EANKS OF YARN.

Application ined May 19,'

and usetul improvement in Machines tor rllreating Hanks ot Yarn9 ont which the tollowing is a specilication.

rthis invention relates to machines tor dyeing, washing, scouring, bleaching or iinpregnating banks ot yarns.

My invention has tor its main object to provide a machine whereby the hunks can be partially or completely immersed. and are given positive continuous revolving motion, a positive continuous rising aid falling motion7 and a positive and closing motion. f

l attain this objectby Vthe mechanism illustrated in t-he `accompanying three she-ets ot drawings, wherein Figure 1 is a view' in vertical section of machine in accordance with myinvention.

.Figure 2 is a plan view, and Y Figure 3 is another view in vertical section thereof.

Figure 4 is a view in a det-ail and is drawn to the other gures. j y

Figure 5 is ay view in vertical section and vFigure G a plan View 'illustrating lication. f l y Referring to the ligures 1to 4C ot the drawings, in the vconstruction illustrated thereinj l provide a vat 1 having afcentral wall 2 which produces two main liquid containing portions 3 connected together by narrow liquid ycont'ainim portions l and also. aA passage 5 through the vat 1. Acoge is provided Acomposed ot two girders Z andv 95 rigidly connected together at the ends by flanged solid plat-es and girders S are slidably mounted on the cage by means oi girders 11 which form with the anges on the plates 10 slots for the ends ot the girders to slide in. For raising and lowering the girders S relative tothe girders 9y it provide cables 12 connected to the girders 8 and arranged to be wound on drumsflB fixed on a shaft A; rotatably mountedL on one ot the girders 7, the cables passing over guide pulleys 15 lixed on shafts 16 which are rotatably mounted on the gire-ers 7. Suitablejmeans (not shown) are provided vertical section ot a larger scale than aA modivto the girders 8 1924. semi No. 714,485.

for arresting this shaft lst against rotation inf onedirection at will. For example a ratchet wheel and pa-'wl maybe employed for this purpose. The cage is tree. to he raised and lowered by any suitable means. have illustrated by way of example a hydraulic ram 17 for this purpose the rain being arranged to project into the passage through the vat and act on a part 19 fixedl by means of bearers 2O to cross pieces 18 secured to the girders 7. i'

Another suitable 4 large worm wheel rotated by means of ay driven worin and provided with a crank pin having an antiiriction' roller which acts on the frame to raise and lower it vertically asy the worm wheel is rotated.

rjfhe bearers QOsupport a cross bearer 2l on which is mounted an electric motor 22 capable of reversal and variation in speed and the motor shaft has a worm 23 mounted on it and meshing with a worm wheel 2e fixed on a'shatt 25 mounted on the girders 7. The shaft 25 has two sprocket wheels 2G tixed on its projecting ends. Two depending plates 28 are fixed to the girders T and carry adjustable jockey rollers 29.

Elongated studs 30 are rigidly fixed in rows l and 9 and each stud carries a rotatable member of flat shape formation constructed of tubes vided on a bush fhavmg a gear wheel 3st fixed to it and provided with a screw threaded end to receive a Vnut V36 which clamps the parts 31 and 32 in position. The gear wheels ot each row arerin mesh with one another and aredriven by a chain 37 from the sprocket wheel Q6, the said chain engaging twoV sprocket wheels 38 fixed to two ot the gear wheels Se on each girder- S and also engaging a sprocket wheel 39 rotatably'mounted on. a'bracket 4:0 which is fixed to each girder 9. The Vsprocket wheel is combined with a. gearfwheel e1 which meshes with one ot the gear wheels 34 of the row or" gear wheels on each girder 9.

Thegear wheels 311 of thelower row' are so set relative to the gear wheels Se or the upper row that the lon-ger cross sectional axis ot'each tube 31 ot the upper row is `dis- 31 of dat cross sectionV mounted between guards 32 which are pro placed 90 degrees relative to the longer cross n sectional axis oi 3l of the lower row.

ln operation the cage is the vet by means ot the hydraulic rain the corresponding tube lifted clear et 1T and tbe shaft 14 is turned so as to lower the girders 8 on the cage. rllhe banks 42 are then slipped on to the tubes 3l, each bank engaging an upper tube and a lower tube. The shaft 1G is then turned so` as to wind the cables l2 onto the drums 14, whereby the banks are straightened or stretched between the tubes 31.

rlhe motor is then started and. causes the tubes to rotate, whereupon the cage is loweredA into the vat which has previously been provided with the liquid necessary for the intended treatment. The banks are thus moved as they enter the vat. The speed of movement can be varied from an initial high speed to. a lower speed or in any other de.- sired. manner. by variation of. the speedv ot the motor andl the movement of the banks` can also be varied by reversal of the motor.

.It will be appreciated that owing to the dat formation of the tubes 351 and`r relative angular displacement of the two tubes or". each' pair carrying a bank, each end ot the bankl will. be alternately' opened and. closed. Furthermore the bank will.y be bodily ciprocated in a vertical direction and will also be displaced in the direction of' their length, thus-setting up an intermittent revolution ot the banks.

Thus rotation of the tubes 3l causes the saidl arms to act on the skeins or banks in three different ways. Inf the lirst place they` displace the banks in the direction of theirY lengthI and-` thus-set up an. intermittent revolutionof the banksthey lift and lower the banksV bodily tor a predetermined distance. In they third placeA they repeatedly force the sides: oi?V skein or hank loop apart and` thene cause` themv to.

approach eachi other. These three movements ensure a thorough and: uniform treat-- ment of all the skeins or banks andV every part of each skeinl or bank without settingy up any unduestrain or friction onthe skeins or banks. As both the upper and lower ends ot'Iv the skeinsV or banks are controlled by the tubes 3l against floating in tribe liquid, they can' be moved at a` comparatively bigh speed without detrimental effects, such as theV entanglement of, adjacent banks arising. After the critical period in the treatment has. passed' the motor is controlled to reduce theA speed of' the shafts whichl are then run slowly tor the remainder of the period of treatment.

rlhe quick movement of the skeins or banks as they are entering the liquid ensures a uniform treatment ot" all parts ot the rskeins or hanks.

lt will be appreciated that in lieu ot a flat bank carrying member, suich. as hereinbetore reterrer to, two or more arms. may be providedy mounted on a bracket which may be .in the form oit a disk. Alternatively oval rollers or their equivalents as bank In the second place.

carrying members or iiat blades or paddles or their equivalents may be provided to rotate about their longitudinal axis.

In the construction. illustrated in Figure 4 the guards 32 act to prevent the yarn or the like from coming into Contact with the driving mechanism orY from `becoming wedged or caught at the ends of the tubes 3l.

lt will be furthermore appreciated that the cage can` be lifted completely out of the vat and be transferred by any suitable means, such as an overhead trolley to another vat for further treatment of the banks carried by the cage. F urtbermore the raifing and lowering mechanism may be employed to raise and lower the cage continuously a suitable distance during the treatment in order to impart a. fourth movement to the skeins or banks under treat'- ment.

Where arms are employedthe arms. ot each shaft are preferably stayed relative to each. or one another at their free ends, the stay means. being arrangedY not to interfere with the placing and removal of the skein or bank.

It' a smaller machine than that illustrated in Figures l to 4 is. required, the construction of cage and vat illustrated in Figures 5 and 6 may be utilized. In. this construction there is only one movable girder 8 and one fixed girder 9 carried by girders 1 0' secured at their upper ends by a g-irder 7 andiixedto end pla-tes l0, cross pieces 1S being providedl for the motor and so forth, andlgu-ides ll being` provided for thegirder 8.. rlbe vat is formed with two angular extensions 43` the interiors of which. are in open. communication with tbe remainder of the interior of the vatanrl serve: to receive tbe plates l0; rlhe arrangement is otherwise similar to that illustrated in Figures. l to 3,y the construction sho-wn in Figures 5 and' 6 being for single sided machine whilst that illustrated in Figures l to 4 is for a double sided machine.

Tbe above described means is applicable for all the bei-einbefore statedV treatments, and makes it possible to employ vat colours in machine. dyeing.
