To aZZwwm t may concern.'

. v Be it known that I, CHARLES D. WITE,

a. citizen of the United States, Norwich,

residing at in the county of New London, in invented a certain new and useful Improvement in Machines for Dyeing Yarns, of which the following is a specification, reference being had to the accompanying drawings.

The-immediate object of this inventionis to provide a reasonably simple machine by means of which yarns may be automatically dyed, oxidized and washed, .in continuous lengths and with absolute uniformity of color or shade;l the whiteyarns being taken in at one end of said machine and the dyed yarns being delivered at the other end of said machine, for the next step in the operation of fabric making.

I My said invention is clearly illustrated, both as a whole and as to its essential details, in the annexed drawings, Figure lbeing'a side elevation of a machine embodying my present improvements and Fig. 2 is an elevation .of the said machine as viewed from the opposite side, that is to say from the side where the driving mechanism is located, the beams ateach end of the machine being removed. Fig. 8 is a plan view of said machine. Fig. LFis a transverse sectional View taken on the line Ll--4 of Fig. l.. Fig. 5 is an end elevation of the guideframe 33. Fig. 6 is a relatively enlarged end view of a pair of squeeze rolls.' Fig. 7 is a perspective view of one of the pipes through which steam is sprayed into the tank.

Referring to these drawings the numeral 2O indicates an elongated rectangular tank which is divided, as here shown, by transverse partit-ions, into four disconnected tanks or chambers 2l, 22,' 23 and 24 and each 0f said chambers is provided with a water pipe 25 by means of which said chambers.

may be conveniently filled with water, and also with a steam-pipe 26 by means of which the water, dye, or other liquid contents of may be conveniently heated and agitated. Mounted upon the main tank 20 are relatively smaller tanks 27 and 2S for the storage of liquid dyes which zuendelivcred into the propel' chambers, by gravity, through discharge pipes 29 and 30, each discharge plpe being provided with a cock l dyed.

wound upon beams, and ready` -in chambers 22 and 23 ltop of the liquid and or valve vby means of which such discharge may be properly regulated.

eferring now to Fig. l, the numerals 3l denote beams of white yarns ready, to be From the beams 31- the yarns pass upward through guide eyes 32 in a bar33 which is, preferably, suspended from overhead. .The' yarns then pass to a frame 34; in which are mounted slats 35fwhieh serve to guide the yarns to at the end of tank 20, which last named slats are so spaced apart from each other that the yarns are kept from engagement, andentanglement, witheach other as the yarns enter the'chamber21, which is filled with water. Chambers 22 and 23 are, preferably, utilized for the liquid dyes and chamber 24 is filled with water.v lIn the passage, successively, through 4the four chambersthe yarns are wet in chamber 21 and are thus prepared to more .readily and are finally washed in the chamber 24.

take vup the dye similar slats 36 located Between the chambers 21 and 22 is al lpair of weighted squeeze rolls 37-38 which 22 and 23 is a like pair of rolls 39%0, and also at the delivery end of the chamber 2i a like pair of rolls Z.t1- 12 by means of which,

the dyed yarns are delivered from the machine in a semi-dried condition ready to4 be passed to, and wound upon, beams 43 or to be coiled in suitable cans.

In the chamber 2l are three idle rolls 21, 2lb, 21, the roll 2lb being located near the the rolls 2l and 2lc being located at or near the bottom of the liquid in said chamber.

Each of the chambers is provided with like idle rolls, similarly located in said chambers, the said idle rolls being provided for the'purpose of so guiding the yarns, in an indirect or angular course, in each chamber, that the yarns will be subjected to the influence of the liquids in said chambers a considerable length of time.

The driving control of my described machine is best seen in Fig. 2 of the drawings, the prime. mover being pulley '44 whichis connected by belt 45, as here illustrated, with a pulley 4G on a horizontal shaft 47 that is revolubly supported in bearings secured to themachine tank. Each pair of the described squeeze rolls is provided with a bevel gear L18,'wliich meshes with, and is driven by, a bevel gear 4:9 secured to the shaft 47, the said rolls being thus driven at a uniform speed in order that they niay serve as feed rolls for the yarns during the passage or" the yarns through the machine and maintain the yarns under constant tension.

Between the chambers 21,22 and 23 and the final washing chamberQJf, the wetted and dyed yarns are caused to pass upward a considerable distance and over idler rolls 5() in order to remove surplus moisture or water and so that the color may be thoroughly oxidized by exposure, for a time, to atmospheric influence. From the roll 50 said yarns pass.

downward and through the washing chamber 24 and, as they leave said chamber, they are squeezed by the rolls l1- i2 and nally pass to the beams 43, or to cans, as may be desired.

My described apparatus and process operate automatically and continually and, because of the constant and thorough agita tion of thedyeing material by steam iii practice passed therethrough, the yarns are colored from end to end with absolute uniformity.

Having thus described my invention, yI claim as new and wish to secure by Letters Patent.

l. Apparatus for dyeing yarns, includingmeans for successively washing, dyeing and oxidizing the yarns, and guiding means for said yarns, comprising a suspended element provided with eyes receiving said yarns, and an element including a plurality 0i' slats over which pass said yarns in entering said apparatus, as stated.

2. An apparatus for dyeing yarns, including a plurality of washing and dyeing chambers, means for supplying dyeing material to -one or more of said chambers, means for passing yarns through said chambers and guiding means for said yarns, comprising a suspended member provided with eyes receiving said yarns and a frame equipped with a plurality of slatsiover which pass said yarns iii entering said chambers, for the purpose set forth. y
