SPECIFICATION forming part of Letters Patent No. 778,236, dated December 27, 1904.

T allwhom it may concern.-

Be it known that I, JOHN W. FRI S, of Winston Salem, Forsyth county, State of North Carolina, have invented an 1m provernent in Machines for Treating Yarn, of which the following is a specification.

My invention has reference to machines for treating yarn; and it consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

The object of my invention is to provide a construction ofmachine which shall occupy small space and have capacity for successive immersions and repeated squeezing during the treatment to insure full and uniform impregnation of the dye or other liquor preliminary to the subsequent drying operations with or without steaming.

My invention is especially useful in dyeing yarns with indigo,-which is soluble in alkaline solutions and which requires repeated clippings and squeezings to secure the proper body of coloring-matter. In the subsequent treatment the soluble indigo is oxidized by exposure to the atmosphere and rendered insoluble by loss of a portion of its hydrogen.

My invention comprehends a vat provided above the liquid-level with a rotating cylindrical roller, and below the liquid-level within the Vat a series of grooved wheels so journaledupon a transverse shaft as to revolve in parallel vertical planes oblique to the cylindrical roller, whereby the yarn in passing alternately about the roller and grooved wheels will advance from one end of the vat toward the other end and at the same time be repeatedly dipped in or treated to the'dye liquor in the vat.

My improvements also include, in combination with the above or equivalent means for treating the yarn, an elastic pressure-roller resting upon the cylindrical roller and adapted to squeeze the yarn as it passes about said cylindrical roller and suitablyrotated so as to remove all retarding friction upon the yarn. My invention also embodies details of construction which,together with the above specified features, will be better understood by ref erence to the drawings, in which Figure 1 is a sectional side elevation of a dyeing-machine embodying my invention on line-w m of Fig. 2. Fig. 2 is an elevation of same with part in section. Fig. 3 is a plan view of the vat and grooved guiding-wheels and upper portion of the apparatus removed, and Fig. Lis a perspective view of one of the bearing-disks.

A is the vat and contains within it a shaft Gr, carried in bearings or supports 1, secured within the vat. This shaft is stationary and has threaded upon it a series of bearing-disks H, having oblique holes to receive the shaft G and are furthermore provided with keyways to receive a longitudinal key or feather g of the shaft. In this manner the disks H are all caused to assume similar positions and lie in parallel planes oblique to the shaft and at the same time to remain stationary. J ournaled upon these bearing-disks H are a series of idler-wheels F, having grooved rimsf. The obliquity of the disks produces a step construction, as shown in Fig. 3, and the projecting faces of the disksact as side bearings to hold the wheels F in position while freely revolving under the driving action of the traveling yarn. If desired, one of these wheels F may be omitted and adivision-plate Aintroduced to divide the vat into two compartments, as shown in Fig. 3, and which would enable the yarn to be subjected to two fluids while in the custody of the machine.

Journaled in upper housings at C C is a cylindrical roller B, of metal, which is driven by gearing D E- and band-wheel E. This roller is located immediately above the shaft G and wheels F and so as to preferably be whollyclear of the fluid in the vat A. The yarn passes alternately about the cylindrical roller B and the wheels F, being advanced by the obliquity of the wheels, as will be readily understood. As shown, the obliquity of the wheels is such that two webs of yarn may be fed through the machine at the same time without tangling, and by varying the obliquity or the diameters of both of the wheels the yarn may be caused to pass over every wheel or every third wheel, as designed. The grooves f of the wheels F are preferably formed with flat bottoms, and this, with the roller B, causes the threads of the yarn web to lie flat or in ribbon form, so as to expose each thread to the fullest extent both to the liquid and squeezing process.

Arranged above the roller B is a tubular rubber roller J, which is flexible throughout and adapts itself readily to the requirements, passing over knots or lumps in the yarn at any point without removing the pressure upon other portions of the yarn. Pressure is applied to this tubular roller by two revolving rollers K L, arranged above it and respectively upon opposite sides of a vertical plane through its axial line. The roller K is journaled in fixed bearings in the frame of the machine, while the roller L is journaled in hinged frames M, and thereby adjusted to or from the rollers J and B under the action of ascrew-shaft N and hand-wheel nuts a. Any other means of adjustment of the roller L may be employed in lieu of that shown. By the adjustment of roller L any degree of pressure desired may be put upon the tubular rubber roller J. To assist the roller J to revolve with a speed commensurate with the roller B, I cause the rollers K L to rotate also at the same surface speed as the roller J, and this I accomplish by providing the said rollers K L with pinions O, which are geared to a spurgear P on the shaft of the roller B by intermediate gears Q. Any other form of gearing may be employed, if so preferred.

I have shown my apparatus in the form I have found excellently adapted for commercial use, and while I prefer the construction shown' I do not confine myself .to the details, as they may be modified without departing from the spirit of the invention.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a machine for treating yarn to fluids, the combination of a vat, a cylindrical roller journaled in the upper portion of the vat, and a series of independently-journaled grooved wheels arranged within the vat to revolve in parallel planes at an angle to the axis of the cylindrical roller.
