DYEIN'G APPARATUS Application filed October 1,1930. Serial No. 485,616.

This invention relates to dyeing apparaf tus, and more particularly to apparatus for the partial or multi-color dyeing of wound masses of yarn.

A particular object of the invention is to provide for applying the so-called Eclipse- I Van Ness hydraulic method of dyeing described in Van Ness U. ,8. Patent No.

1,456,344 to the partial or multi-color dyeing of packages of rayon yarn. It has been found that the particular injecting apparatus described in said Van Ness U. S. Patent No. 1,456,344 and in the later Van Ness Patents, Nos. 1,577,884 and 1,606,196, while highly satisfactory in the dyeing of otherkmds of yarn, is not applicable to the dyeing of rayon yarn becausethe construction of the plicable to rayon, the use of the new machine is by no means limited to dyeing rayon, as it may be applied to all other kinds of yarn.

The invention will be further explained in connection with a detailed description of a practical dyeing machine embodyingthe invention and illustrated in the accompanying drawings, in which: I

Fig. 1 is a plan view with the'base plate partly broken away, showing the yarn mass spaced from the injectors;

Fig. 2 is an enlarged longitudinal section taken on the line 22 of Fig. 1, and showing the yarn mass in position for dyeing;

Fig. 3 is a partial transverse section taken on the line 3-3 of Fig. 1, showing the pump;

Fig. 4 is an enlarged horizontal section taken on the plane of the axes of the dye nozzles, which is indicated by the line 4-4 in Fig. 5; and

Fig 5 is a front elevation of thepresser and injector nozzles.

a multi-color dyeing machine similar in general construction to that shown in my Patent No. 1,726,984. It includes a baseplate B carrying a multi-cylinder pumpP and'a workholder W. In the operation of the machine, the pump draws-different colored dyes from aplurality of separates reservoir'sTa, Tb, T0 andToZ, and forces limited quantities of the different colored dyes into separate portions-of a mass of yarn on the workholder N through a plurality of nozzles J in a presser .A whose constructlon constitutes a particular feature of the invention.

The means for operating; the pump andfor supporting, translating and rotating the spindle of the workholder are identical with 'those described in my Patent No. 1,726,984,

The machine illustrated in the drawings is to which referenceis made-for a detailedzdescription of these parts which maybe readily applied tothe drawingsof the present application, since the reference numerals used in said patent have been applied to the identical or corresponding parts shownin the drawings ofthe present application. It should holder W is provided with a cylindrical extension VV4 adapted to fit the bore of acylindricalbobbin or. core C1.

The portions of the machineillustrated which cooperate directly with the yarn differ from those shown in my patent above referred to. The yarn mass C consists of a thin,

hollow, cylindrical layer wound on a cylindrical core 01 whose radius is several times as great .as the depth of the yarn mass. The

ings P24 of thepump cylinders. The outer:

vertical surface A1 of the presser is concave and cylindrically curved, having substantially the same radius as the outer surface of the yarn mass C, so that, it is adapted to fit evenly against a portion of the circumate-zones of "the compressed portion which separate the parts of-this portion into which ferential surface of a yarn mass from one end of the mass to the other. The presser contains a plurality of holes or bores A2 extending through its surface A1 and connected in groups by passages A3 with the outlet openings PM of the pump cylinders. In the outer end of each bore A2 is seated a nozzle A4 which most desirably projects from-the surface A1 of the presser.

It will readily be understood'that, when the workholder Wis operated to 'm'ove'the yarn mass toward the pump into the position shown in Fig. 2, the surface A1 of the presser A fits against the circumferentialsurface of the yarn mass 0 and evenly compresses an extended portion of this surface. While the machine operates verysatisfactorily with a portion of the yarn thus evenly compressed,

"anadv'a'ntage is gained by 'p'roviding "foran additional compression of narrow mtermedidifferent colored dyes are injected. Inthe machine illustrated, such additional com- \pression: is secured byiprovidin'g the pressing surface A1 of the presser A with projecting transverse ridges A5, which are located between the sets of nozzles A4 communicating with the-.dilferent pump cylinders. I

The use of themachine from the operators ,point of viewis'the sameas that described inPmy-Patent No. 1,726,984. The workholder is 'reciprocated towards and away'fromthe lpu'mp. At the end of each inward stroke, a 335;

portion: of the :yarn is evenly compressed by the surface A1 of the presser A, and the pump then makes one compression stroke which forces the dyesof different colors under equal pressures intodiiferent parts of this evenly 'compressedportionof the mass. The shaft -of the workholder is rotated slightly'after each outwardstroke, so that successive sectors of the mass are dyed in four colors until at "the end of the operation there are'four-bands .%45-

ofdifferent colors extending around the mass. The pressure exerted I by the pump pistons "issufficie'nt to cause the dye injectin g'from each nozzle to penetrate through the shallow ma s's from its outer to its inner surface in i the absence of any mechanically opened passage for the'injected dye. This, combined with theevenfpressureon'theportion of the mass being dyed, results in a very'even spreading ofthe dye. 'By'proper adjustment of the between thedifl'erent colored bands-in the mass, avoiding any undyed portions between the bands andany substantialoverlap-ping or mixing of the colors; The dyeing the compressed portion in the absence of i my hand.

in each band is uniform from the outer surface to the inner surface of the mass.

What I claim is:

I 1. Apparatus for dying a wound mass of yarn, comprising a presser having an extended concave surface formed tofit against a. circumferential surface of the mass of yarn seas-evenly to compress a portion of the mass, and means for injecting dye through the presser into a portion of the'yarn'compressed 'by said surface 2. Apparatus for dyeing a. wound mass of yarn, comprising a presser having an extended concavesurface adapted to fit against a surface of the mass so as evenly to compress "a portion of 'the m'a-ss, a plurality of nozzles 'p'rojecting from said surface of the 'presser,*anduneans for injecting dye through said nozzles simultaneously into -a portion of 'the mass compressed by the presser.

. 6.
