` Application filed March 5, 1919. Serial No. 280,723.

To all whom t may concern Be it known that I, JosErH A. FIRSCHING, a citizen of the United States of America, and resident of Utica, in the county 1 of Oneida, in the State of New York, havein-v vented new and useful Improvements in `Dyeing-Machines, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in dyeing machines and is particularly designed for intermittently applying dye to traveling yarn, thread or the like. The ob: ject of the invention is to produce an efficient device of quite simple construction for dyeing spaced lengths of yarn as wound from one bobbin to another by wiping the yarn'across the dye carrying applying ele-v ment without independent movement of the yarn either toward or from. said element and preferably the parts are so formed and arrangedas tol give the yarn a rolling movement nwhile in contact with said element .whereby the dye is applied more uniformly throughout thev entire circumference of the Other objects and advantages relate to the Vdetails of construction of the dye carrying applying element as will more fully appear from the following description taken in connection with the accompanying draw-- ings in which,

Figure l is atop plan view of a portion.

Fig. 3 is a cross section on line takenat rightangles to Fig. 2.

`Flg. t is a view similar to Fig. of a )modified form of machine.

Fig. 5 is a view similar tol machine illustrated' in Fig. 4.

As shown in Figsl to 3 inclusive` 4the machine comprises a tank l formed of .a metallic cylinder 2 having its ends closed by caps 3 combined with locknuts 4. and4 interposed packing 5- insuring a liquid tight joint. Arcuate portions of the wall of c'ylinder 2- are cut out or removed and substantially flat kplates 6 are fitted into the recesses so formed and have Hanges -7 fitting the adjacent portions of the wall of the cylinder 2 and secured thereto as by screws 8 The plate 6- is provided with a groove with a central Fig.,8,"of lthe orfchannel 9 in its upper exposed face and this groove preferably as shown extends from one end along one edge of the plate for a short distance, then diagonally across the plate to a point spaced from the opposite end thereof and then along the opposite edge to said opposite end, for a purpose hereinafterl described. The plate 9 is provided opening forming a communicating passage way between the said groove or channel and theinterior of thetank 1 The plate may be formed or providedwith substantiallyy circular pins 10- risingin the channel 9- tofguide the yarn through the diagonally disposed portion of the channel.

'F or the purpose of intermittently applying dye to the traveling ment llis provided, vformed with one or more (in this instance eight) radially projecting dye carrying applying parts 1 Vsuch parts move successively through the opening in plate G into the.

channel 9 for contact with the moving yarn as the said element is rotated.

yarn, a rotary elej soi VAs shownthe element 1l is built up' i from a series of dye absorbent disks 13 M and l5 the disks 18 and 141- serving only to assist in uniformly supplying dye to the dye applying parts l2 which are formed in connection with and in this illustration as a part of the central disk 15 In other words the central disk 15 may be formed in much the shape of a gear, the projecting teeth constituting the dye carrying applying parts. 13 l4. and l5 are held in as` sembledv position by a pair of oppositely disposed plates 16 and 17 kone of said plates-as 16 provided with an axially projecting flange l8 extendingy through the absorbent disks and the plate 17 and having its Vend threaded for interlocking engagement with nut l9 The element so formed may be carriedV by sleeve 20 mounted upon shaft 21 having its oppo# i site ends journaled respectively in varms 22 and 23 carried by plate The disks sired be pivotally carried from downwardly the same manner as element lland forming a substantial counterpart of said element. T he absorbent dye carrying disks -28--, 2.9- and M30- are each provided with peripheral cross grooves or recesses forming with and constituting a counterpart of the projecting teeth or parts #12* of disk l5- and as disk-15* meshes primarily with the said disk 2Q- dye will be uniformly applied to the dye carrying applying parts nl2--. The driving of disk -lmight be effected by its meshing relation with disk -29- but preferably perhaps, as shown, the additional positive drive is provided through the medium of plates --16- and 17- and -25- and Q6- respectively. The plates "1G-.- and -17- do not project beyond the periphery of disks --l3- and --lll-` `whereas plates E25- and -25- have teeth projecting outwardly from the greatest diameter of the disks 25 and -25--. As shown the dye feeding roller -27- builtup as described may be of considerably less diameter than the element -llso that the element --ll-- is rotated at a yslower speed. The

feeding roll ,-27- may@ be mounted upony shaft 31- driven through any suitable connections and preferably by the mechanism described in my application Ser. No. 230,722, filed March 5 191% whereby the speed of said shaft varies with the speed of the traveling yarn. i

The operation will be readily understood. Lis the element -llrotates, the dye carrying applying parts will be successively and at spaced intervals moved through the opening` in plate -G- into contact with the yarn traveling through the channel -9-. The yarn will be wiped across the moving part or tooth and thereby dye will be applied to the yarn. The movement of the yarn across the element lldiagonally of plate 6.- and at an angle other than a right angle with the axis of element -11- will cause` the dye applying part 12- to give to the yarn a rolling motion as it is wiped across the said part whereby the dye will be substantially uniformly applied to the entire circumference of the yarn. Guides -.-32- and --83- may be provided for causing the yarn to move through channel -f9- at the desired elevation.

In Figs. l and 5, I have illustrated a modified form of device in which the element 1lis mounted directly upon shaft 3land the feeding roller -30- is omitted, the dye carrying applying parts picking up their own dye from the body of the same contained by tank -2-. In this construction the element is formed of the three absorbent disks --l3---a llland -15-, the latter having the projecting dye applying parts l2- These disks are confined by a plate -33-, the parts being held in this assembled position by nut -37- having a threaded relation with the end of sleeve 311- adjacent the washer -36-j. The sleeve -34*- may as shown be set-screwed or otherwise secured to shaft -31-- for rotation therewith. This structure operates to apply dye to the traveling yarn in substantially the same manner as the structure of the former figures. It is found however, that the feed and application of the dye is perhaps somewhat less uniform than when J[he feeding roller --27- is utilized. Y

It will be noted that the structure in essence consists of a series of spaced dye carrying applying parts mounted for rotation upon a common axis and adapted to be brought successively into wipingcontact with the traveling yarn. The speed of rotation of element 11,- and the spaced distance of the dyeing parts -12- may be so regulated and predetermined as to' dye the yarn in desired lengths spaced a uniform predetermined distance apart, upon condition that the speed of shaft .--Blfis synchronized with the speed of the traveling yarn. Y Otherwise the dyed lengths and the space between the dyed lengths will vary in accordance with the variations in speed of the yarn assuming that the speed of element --ll,-- is substantially constant. My invention includes both methods of opera tion as the structure is adapted for either.

In the operation of the structures illus- `trated it is a practical essential that-the yarn be maintained in a proper position rela-4 tively to the periphery of the dye applying elements and to the effective operating surface of said elements.v If the yarn moves longitudinally in 'such a position that the dye applying elements project radially of the wheel too far beyond the yarn the lateral thrust when the element comes in contact with the yarn will tend to break the latter. For this reason I have provided an adjustable supporting means for the yarn so that its position may be accurately and delicately predetermined and varied to hold the yarn in the proper position.

This means as illustrated comprises a pair of hookshaped members positioned upon opposite sides of the rotary dye applying parts l2-f and preferably these members are jointly formed of a single piece of wire bent to desired shape so as to form the oppositely disposed hook shaped parts -38-- and the intermediate integral part .-39-. The yarn supporting device so formed has its opposite ends carried in any suitable adjustable manner as from post 40 supported from plate'. Post 40 may carry a pair of spaced nuts 4lbetween which a pair of clamping plates 4% are secured, such plates having concavities at their opposite ends for gripping the ends of the yarn supporting member. By adjusting nuts 41- along post -t0 the proper relative position of the yarn supporting member may be determined. Although the dye applying parts l2- may be of various shapes, my experience leads me to believe that preferably they should be part-s of spheres of relatively Asmall diameter.

Although, I have shown and described a particular construction of apparatus including a specific built up construction of element 1l- I do not desire to limit myself to the structure shown or to the particular form or relation of the parts as illustrated. Various changes may be madeiin the details of form, construction and arrangement Without departing from the in vention as set fort-h in the appended claims.

Vfhat I claim is l. In a dyeing machine a rotary gear shaped absorbent disk and means for supplying dye to the disk.

2. In a dyeing machineV a rotary gear shaped absorbent disk and a gear shaped roll for feeding dye to the disk.
