- Application filed December 22, 1923. Seria1;No. 682,301.

To allwhom it mag concern:

Be it known that we, JOHN IBRANDWOOD, THOMAS. BRANDWOOD, and Jossrn BRAND- woon, subjects of the King of Great Britain and Ireland, and residents of Elton, Bury, England, have invented certain new and useful Im rovements in Apparatus for Dyeing ound Yarns on Spindles, of which the following is a specification.

This invention relates to apparatus for the treatment with liquids of yarn packages, e. g. cheeses, and the subsequent handling of such yarn packages for the drying, and other treatment of same, the treatment of liquids being effected by placing the cheeses on spindles, compressing same if desired, them by means of a pump in the manner described for instance in our pending application No. 640539 of the 2lst May, 1923,

wherein the spindles employed are fluted.

dles of the apparatus,

In such treatment the fluid for instance dye fluid, passes from a pumpto a lower chamber, thence to the flutes of the various spinand thence through the yarns mounted on the spindles and into the dye bath in which the apparatus is fitted, the flow of liquor bein In some cases it is found that t iere is diflicul y in removing all the cheeses after liquor treatment, as the yarnsleontract owmg to such. treatment and compress the cheeses upon their dyeing spindle, and further it is not in all cases expedient to emloy the process described: in our said pend-- ingappl-ication viz; to slip the cheeses off their spindles and pass each directly on to a central holder of the same cross section as thedyeing spindle. I

The p' 'esent11nvention has for an ob ect an apparatus for dyeing'yarn packagesmn spindles in such a manner that they may be easily removed therefrom, thus saving possible waste of yarn and' also saving time in time erat-ion, with subsequent mountln of the c eeses on central holders in ar'api and extremely simple and inexpensive manner. In carrying it into effect in the treatment of yarns wound inthe form of cheeses, we take the cheeses to be treated, and remove the central paper or like tube on which the have been wound, this 0 eration being easily efiected by pressin t e tube out. *The chee'sesare then place on dyeing spindles,

These spindles are not 0 equal diameter throughout; they taper upwardl to an desiredor convenient degree, an are he din position in the-apparatus in such a manner that they may when desired be displaced downwardly in relation to the cheeses held treatment on the spindles is completed the spindles are loosened and pressed down wardly, thus breaking contact of the inner windings of the yarncheeses with the s in- 'in s, wherein igure 1 is an elevation partly in sec tion of an apparatus comprising a lurali ty of dyeing spindles, on y some 0 which are shown for clearness of description;

This taper is shown exaggerated at the right hand'in Figure 1. For the purpose ofthe invention this taper may be very little. 12 is a central rod which as shown is screwed into the plate 6 which is tapped for the purpose. This central rod 12 may be a plain rod having a hook or ring at the be hereinafter referred to.

upper end thereof, or it may be arranged to receive a special pressing apparatus to 13 indicates cheeses placed upon the spindle 11.

Screwed into the plate 6 are a number of annular plates 14 having extensions 15 tlielower ends of which are threaded for the purpose. The internal diameter of these plates and the extensions 15 is such that a spindle 11 will fit therein with :a fairly tight sliding fit. One of these plates hereinafter referred toas spindle holders is provided as the holder for each dyeing spindle in the apparatus. At one side of each spindle holder is fitted the stop or slide member 16 the inner end of which projects through the wall of the tubular extension 15 of the holder to engage between two flutes of the dyeing spindle. The slide member is threaded to receive a nut 17 to hold it in. position. At a pointdi ametrically opposite to the orifices formed for .the inscrtion of the slide member end the tubular extension 15 is tapped to receive the threaded end 18 of a thumbscrew 19see Figure 3which when screwed in position serves to keep its spindle '11 in position within .the plate 6. Upon the lower end of each spindle 11 is fitted a plate 20, secured to the spindle in any convenient manner, which serves to limit the upward movement of the spindle within its holder 14.

In carrying out the operation of dyeing of the cheeses we proceed as follows :The spindle 11 being in position as sh wn in Figure 1 and held therein by the thumbscrews 19, a washer 21 is placed upon each spindle holder 14. Cheeses 13 from which the central paper or like tubes have been removed are then placed upon each spindle until the latter is full. After the apparatus has been thus charged the cheeses may be compressed upon each spindle by any approved means. \Vhen the cheeses are thus prepared, the dyeing proceeds by the foreing of the dye liquor into the/chamber 5 through openings 7 from a pump (not shown), the liquor proceeding up the flutes of the spindle 11, which are open to the chamber as will be evident from. the drawing Figure 1, and thence through the yarns of the cheeses 13-into the dye bath or receptacle inwhieh the whole apparatus is placed. The flow of liquor may then be reversed and this continued as long 7 as \necessary. Then the liquor treatment 1s completed, the thumbscrew 19 is'then removed from a spindle 11, thus leaving the latter free and pressure-is applied to' the top ofthe spindle to force it downwardly, the depth of the liquor chamber o'allowing for this. As the spindle moves downwardly whilst the holder 14 and the cheeses remain stationary, it will be evident that when the downward displacement is complete, any

cheese 13 will be on a diameter of its spindle 11 which is less than the diameter on which it was originally placed, the cheeses 13 being thus loose on their spindle. They may then be removed easily, and dried in any suitable central rod12 in the presentdescription r and 'drawingsand bearing a pressure member which presses downwardly upon a top plate placed on each dyeing spindle. In order to utilize this for the pressing downwardly of each'spindle 11, we may employ the pressure member 22 shown in Figure 4 of the drawings hereto annexed. The pressure member may be of the configuration shown, and have a recess 23 formed in the upper face thereof. A pin placed in a hole in the lever before mentioned may fit into this slot, and downward pressure of the said lever will through the pressure member, force the spindle 11, upon which the pressure member has been placed, downwards. If desired the upper-end of each spindle may be slotted as shown at 23 Figure 4, and lugs 24 be formed upon the pressure member to'fit in the said slots.

WVhen the cheeses have all been removed the spindles '11 are drawn up to the posi tion shown in Figure 1 and the screws 19 replaced to hold the said spindles in position for a further dyeing operation.

We have described the invention as being applied to yarn packages a plurality of which'are placed on a single dyeing spindle, the latter being of a length suflicient to take such plurality of packages. It will be ob- 'vious however that if found convenient the invention may be applied to yarn packages which are mounted single upon dyeing spindles, the spindles of course being tapered. Also, although we have referred to fluted 'spindles, the invention may be equally applied to tubular perforated spindles, as, by tapering latter, the dyeing and subsequent handling of'tlie yarn packages can be carried out in exactly the same manner as hereinbefore described."

It will be understood, that we do not claim in this application the'method per se of dyeing cheeses in the compressed state or otherwise by means'of mounting them on fluted dyeing spindleswhich are in communication with the liquor chamber.

We claim: v 1; A support for cheeses of yarn, comprising hollow chamber for dye provided with a spindle holderfatits top'having a'plate ill) for supporting the cheeses, an upwardly tapering spindle for positioning the cheeses having its lower end portion slidable downwardly in the spindle holder and provided with passages for dye which communicate with the said chamber, and a fastening device for locking the spindle in the spindle holder at will.
