IBLEACHIN G, DYEING, OR OTHER FLUID TREATMENT OF YARNS WOUND IN THE FORM OF CHEESES.

Application filed December 22, 1923. Serial- No. 682,803.

To all whom it may concern:

Be it known that we, JOHN BRANDWOOD, THOMAS BRANDWOOD, and JOSEPH BRAND- WOOD, all subjects of the King of Great Britain and Ireland, and residents of Elton, Bury, in the county ofLancaster, England, have invented certain Improvements in and Relating to the Bleaching, Dyeing, or Other Fluid Treatment of Yarns Wound in the Form of Cheeses, of which the following is a specification.

This invention relates to means for compressing yarn vpackages which have been placed upon perforated or analogous spindles for the purpose of dyeing or other treatment of the yarn packages, as described for instance in the specification to United States Letters Patent No. 1454312 granted' to two of the present applicants. .It is a necessity, as pointed out in the said prior specification, that when the-yarn in the form of cheeses is to be dyed in bulk, the yarn of all the cheeses should be of equal density, to prevent uneven penetration of the dyeing liquor or analogous fluid. The gravity plate and screw means described-in such prior specification, whereby all the cheeses on a plurality of spindles are compressed by the weight of a top or gravity plate which is further pressed down by a nut engaging on a threaded central spindle, requires careful handling and attention to ensure that the pressure shall be equal on the yarn contained.

on each spindle, and means for compressing the yarn mass on each spindle singly, whilst ensuring that the pressure of the yarn mass of one spindle shall be equal to the pressure on the yarn mass of another, is a desiderafor each perforated or analogous spindle a '45 turn. It is the-object of this present invention to provide such means of even compression.

In carrying the invention into effect in an apparatus as above referredto we provide separate top plate adapted to slide upon the spindle, with means for pressing each top plate separately upon the yarn mass upon the spindle, and means upon the spindle itself for securing the top plate in fixed relation thereto when the compression has reached a given point. Thus with a yarn bulk of equal-compressibility on the whole a of the spindlesft securing means as between the spindleand' top plate after the fitted upon a spindle with means for pressmg 1t down upon the mass of yarn cheeses fitted upon the-spindle;

Figure 2 is a side elevation of a top plate upon a spindle, the pressure means being removed, and the securing means applied to the top plate;

Figure 3 is a view similar to Figure 1 but at right angles thereto; and

Figure 4 is a fragmentary view in side elevation showing two spindles. with top plates, the yarn being compressed on each spindle and ready for treatment.

Referring to Figure 1, 5 is acentral rod or spindle which correspondsto the central rod or spindle of the drawings to specification No. 1454312 referred to above. This rod 5 is threaded at 6 to receive a tapped cylindrical member 7 in which are fitted pins 8 one at each end of a diameter of the cylindrical members. 9 is a lever of any convenient length the end 10 of which is bifurcated, each limb of the bifurcation being slotted as at 11 the width of the slot ll'being suflicient to allow of each limb of the bi urcated end 10 being slipped over a pin 8 12 is a bell shaped pressure member which may be cast and has formed thereon the lugs 13 14.is a top plate annular in form and the diameter of which is equivalent to the diameter of the cheeses 15 fitted upon a perforated spindle 16 when the said cheeses have been fully compressed. The

top plate 14 is provided with tubular boss or extension 17 of a diameter equal to the external diameter of the pressure member 12 at the base of the latter, or of any less diameter. The top plate 14 andits extension 17 have an easy sliding fit on spindle 16.

' At the .desired distance below the upper extremity of each spindle 16 is formed an orifice 18 (Fi ure 3) which extends through the wall of the said spindle, and the lower portion of the bell shaped member '12 is cut outas at 19 Figures 1 and The lever 9 has orifices formed in it at 20 and 21 through which a pin may be passed.

The method oi? operation is as follows: Cheeses of yarn 15 are slid upon a spindle 1 16 until the latter is filled, this operation being conducted with regard to all the spindles of an apparatusof the type described in the prior specification No. 1454312. On each spindle is then placed the top plate 14. The cylindrical collar 7 is then screwed upon the central rod 5Figure 1,and the lever 9 fitted thereto by means of its bifurcated end 10. The bell shaped pressure member 12 is then fitted to the lever 9 by a pin 22 which passes through holes in the lugs 13 of said member and through hole in the lever 9. This hole 20 .is so situated that when the pressure member 12 is fitted to the lever the said pressure member will hang directly over a top plate 14 of a spindle 16 as shown in Figure 1. Downward pressure being then applied to the handle end of lever 9 the pressure member 12 forces the top plate 14 downwards, thus compressing the yarn mass beneath it. The position of the hole 18 in the spindle has been predetermined so that When sufiicient pressure has been applied to the top plate 14' to give the desired degree of compressibility to the cheeses the upper end of the extension 17 thereof has just cleared the lower edge of the hole, and the latter is visible to the operator through the; slot 19 into the pressure member. A pin 23 is then inserted through hole 18 to keep the top plate 14 in position, and the pressing means can then be applied by means of lever 9 and pressure member 12 to the top plate 14 of another spindle- 16 in the apparatus. The lever can be moved angularly around the rod 5 for this purpose, owing'to the screwed connection of said rod and the collar 7 which supports the said lever.

Obviously any number of holes.20, 21,

may be formed in the lever corresponding to the number of concentric rows of spindle 16 in the apparatus; and any number of holes 18 may be formed in each spindle 15. Where large batches of one kind of yarn are to be dealtwith the invention presents a conspicuous advantage; inasmuch as only one hole may be made available in each spindle for the insertion of a pin- 23; and it is therefore out of the power of a care-' less operator to give uneven pressure to the yarn mass on one spindle as compared with another.

In order to give a support to all the I si lvindles of any apparatus, when they are led with cheeses compressed as described above, and when the apparatus is being handled in the course of dyeing or analo-' gous treatment of the yarns thereon, we may provide a circular plate 24Figure 4-which is provided with orifices at the necessary points to allow the said plate to he slipped over the extension 17 .of'the top plate 14 on all the spindles and the central rod 5 to rest, and being secured in place by a nut lightly screwed down thereupon with the interposed washer on the rod or spindle 12 which is threaded for the purpose.

We may alter the details given without departing from the spirit of the invention. For instance, the pressure member 14 may be a plain cylindrical tube of the necessary dimensions having diametrically opposite longitudinal slots in the upper end thereof, and the pin 22 of lever 9 be a permanent fixture in the said lever, one pin being fitted in each of the holes 20 and 21. The pressure i'nember, thus modified, being placed in position, the pin 22 on pressure bein applied to the lever 9 would fit in the slots in the pressure member, thus imparting the necessary compression effect to the cheeses 15. i We claim v 1. The combination, with a spindlefor supporting cheeses of yarn, of a retaining plate slidable on the spindle, a sleeve slidable over one end'o-f. the spindle and bearing on the said plate,.means for sliding the sleeve so as to compress the yarn, and means for preventing the return movement of the said plate after the yarn has, been compressed. '2..The combination, witha' spindleprovided'with a cross hole and adapted to support cheeses of yarn, of a retaining plate slidable on the spindle, a sleeve slidable over one end of the spindle and having a slotted end which bears against the said plate,

means for sliding the sleeve longitudinally on the spindle, and a pin for engaging with the hole in the spindle, said pin being inserted through the slotted end of the sleeve on. the other side of the retaining plate from the compressed yarn.

3. The combination,- with a. spindle for supporting cheeses of yarn, of a retaining plate 'slidable on the spindle, aremovable sleeve slidable over one end of the spindle and adapted to bear on the said plate, a stationary support provided with a revoluble member, a lever pivoted'to the said member and to the said sleeve and adapted to slide the said plate onthe spindle to compress the yarn, and means forpreventing the return movement of the said plate after the yarn has been compressed, the said lever being movable circumferentially. of the said support to compress the yarn on other-similar spindles.

In testimony whereof we have hereunto set our hands.
