DY EING APPARATUS Original Filed March 11 1926 INVENTOR ATT RNEY Patented Ma 20, 1930 nanny n. vsn nnss', or 1., NEW YORK 1 prismahrieanaru's en mel application filed March 11, 1926, Serial No. 93,321. amass and an application men are." 27, 1926. Serial No. 144,13. Renewed November 9, 1929.

This invention relates to dyeing apparatus and more particularly to apparatus for carrying out the method of dyeing one or more predetermined parts of an absorbent mass, which is described and claimed in Patent No. 1,7 24,-

015, issued to Eclipse Textile Devices, Inc. on August 13, 1929. .The present application is a division of my co-pending'application filed March 11, 1926, Serial No. 93,821.

The object of the apparatus with which the present application is concerned is to facilitate carrym out the method of dyeing in which the through a predetermined limited part of a s wound mass of yarn, coloring this part of the yarn only; and more particularly to aidv in carrying out a specific method of spot-dyeing." yarn-wound in the form customarily known as a cross-wound cone of yarn. This specific as method, which is described and claimed in my aforesaid co-pending application, is as follows 1 c The cone is placed with the axis, of its core horizontal and is rapidly rotated about this axis. During the rotation, the liquid is poured on any desired zone of the inner surface. of the core. The liquid reaches the inner surface of the mass through perforations provided in the core. The perforations need not be limited to a particular zone of the core, but maybe formed throughout the core, as the particular zone dyed isdetermined' by pouring li aid on that zone only; Thehquid is.-

poure at such ratethat the centrifugal force causes it to enetrate into the mass immediately'from t e point at which it strikes the inner surface of the core. In consequence, the liquid cannot spread over the innersurface of the mass or the inner surface of the perforated core, and so. does not enter any part of the mass other than the zone lying radially outward from the point at which it is poured on the inner 'surfaceof the core." The supply of liquid to. the inner surface of the zone is thenstopped, and the rotation is continued; until no l'fu'rther liquid or mist is thrown off from the outer surfaceof the zone. .This results in leaving the zone, which has been dyed, substantially dry,and thus eliminates all danger of subsequent coloring of other -forated c0re,-it is "also applicable to any 5 yeing liquid is passed rapidlyparts of the mass by liquid soaking into them from the dyed zone. r While I have described this s ecific method as applied to a cone provide 1 with a perwound mass from'which the core has been removed so thatthe-inner surface of the mass is directly exposed. I v

A convenient form of apparatus, embodying the present invention, and adapted toa1d to.

incarrying out the method described is-illustrated in the accompanying drawings in which:-' Fig. 1 is an elevation in axial section; and Fig. 2 is a similar view showin a modifica tion of the apparatus shown in fig. 1.

Theapparatus illustrated comprises a ro Ft ary shaft 10 and a foraminous fr'usto-conie cal holder 15 secured to one end of the shaft. The shaft and holder'ar'e mounted with their "0. axes horizontal. The cone of yarn C to be dyed in this apparatus may have a core G which is perforated throughout. The liquid is supplied to a predetermined zone'of the inner surface of the mass through a pi e 25' which is mounted for adjustment lengt wise of the aiis of the cone'sothat the liquid di rected from its outlet 32 may be supplied to any desiredzone of the inner surface of the mass. Such adjustment is e'flected by moving a receptacle 33 from which the pipe 25" extends along a rail 34 which is parallel to the. axis of the cone.- In using this device, the liquid is not supplied until after the rotation of the cone is started, and its flow is regulated by a valve 35 to such extent that the liquid striking the inner surface of the core 0 is thrown directly into the mass by centrifugal force before it can flow along the inner surface ef the vcore or the inner surface of the mass. Y

It is apparent that the apparatus shown in Figlmay, izE desired, be used in connection withf'a core-havinga setof perforations only at the zone to be dyed, aiid also that it may be used in connectionwitha mass containing no core. I I

If it is desired to dye more'than one zone, the apparatus shown m Fig. 1 may he modiwe fied as indicated in Fig. 2 b providing a pipe 25 with more than one out e What I claim is:

Apparatus for dyeing, comprisingmeans for rotating a 'mass of yarn containin a central opening, a, pipe extending into 1: e central opening%' of the mass and having a discharge nozz e; and means for adjusting said nozzle in a dlrection'parallel t0 the axis of 10 the mass so that it will discharge 1i(1id at any desired zone of the inner surface 0 the mass. In testimony whereof I have hereunto set 111 hand.
