SPEGIFIGATIQN forming part of Letters Fatent n os,'2e1, dated November 7, 1893. Application filed November 21, 1892- Serial No. 452,691- (No model.)

To all whom it may concern: I

Be it known that I, LEONARD WELDON, of Amsterdam, in the county of Montgomery, in

' the State of New York, have invented 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 is animproved organization of that class of dyeing machines in which a,

drum or cage has its interior divided into compartmentsfor the reception of the articles or material to be dyed, and is arranged with its axis horizontally in such a position in the dye-vat as to cause the material under treatment to be alternately dipped into the dye-liquor and carried out of the same.

My present invention is designed more particularly for dyeing raw stock, wool or cotton, and the object of the invention is to guard against the rolling and matting of the stock during the process of dyeing the same, and to dye the stock evenly throughout; and to that end the invention consists in novel devices applied to the interior of the'rotary drum or cage for the purpose of intercepting and gradually releasing the stock in its move ment to different portions of the conipart: ment in\the cage duringthe-rotation ofthe cage as hereinafter more fully described and specifically set forth in the claims.

In the accompanying drawings Figure 1 is an end elevation of a dyeing machine'embodying my invention. Fig. 2 is a transverse section of the same on line y, 1 Fig. 3. Fig. 3 is a vertical longitudinal section on line 2, z, in Fig. 2. Fig. 4 is a transverse section of a modification of my invention, and Fig. 5 is a longitudinal sectional View on line w, 00, in Fig. 4.

Similar letters of reference indicate corresponding parts.

A- represents the vat or tank containing the dye-liquor.

C- denotes a horizontal shaft which is journaled in suitable bearings secured to the end-walls'ofthe vat. On the said shaft is rigidly mounted the drum or cage .B- con structed partly or wholly ofopen-work so as to allow the dye liquor to pass freely through it. To one endof'the cage is fastened aspurin bearings on the exterior of the vat.

wheel D' which meshes with a pinion D' rigidly secured to a shaft which extends lengthwise of the vat and is journaled in bearings secured to the ends of the vat. To this shaft is also secured a worm-wheel H- which engages a worm H mounted n the worm are mounted the fast and loose pulleys 'II' which are connected by a drivin'g'belt to the pulley of the motor, not shown. By throwing the belt onto the fast pulley rotary motion is imparted to the cage -B' said motion being in the direction indicated by arrows in the drawings. The interior of the cage is divided into two or more compartments by radial partitions P which are also constructed of open-work to allow the dye-liquor to pass through them. I preferably construct said partitions of perforated sheets of copper secured to longitudinal bars bbattached to the heads of the cage or otherwise properly sustained in position. Each of the compartments is provided with a suitable gate cthrough which to introduce the raw stock or other article to be dyed. Said gates may be either hinged to the cage or otherwise adapted to'be opened and closed. Lengthwise of each compartment extends a rib d which projects from the axis of the cage part way toward the periphery thereof so as to form thereat a throat for the passage of the material undertreatment from one side of the compartment to the opposite side thereof during the revolution of the cage.

RR represent horns which are fastened to the ribs d -d and project from the outer edges thereof part way toward the periphery of the cage.

To the periphery of the interior of the cage are pivoted a series of hooks ee arranged in rows parallel with and directly opposite the ribs --dd. These hooks are pro vided with stops or shoulders e" back of their pivots to brace the hooks so as to prevent them from swinging rearward from'an approximately radial position, said hooks being allowed to swing freely in the opposite direction, and thus move in an arc of about --ninety degrees.

shown, and is extended into the vat, preferably at or near the base thereof and arranged in any suitable manner to boil or heat the dye liquor to the required temperature.

In the operation of the machine the revolving cage B carries its two compartments alternately into and out of the dye-liquor and thus alternately dips the stock or material under treatment into the liquor and lifts it out of the same and while in the latter position the dye liquor drains partly from the stock and returns to the vat and exposes the stock to the air. It is obvious that as each compartment is carried out of the dye-liquor the stock is carried toward that side of the compartment which leaves the dye-liquor last, and the stock is retained there by the rib d until the latter is turned beyond a vertical line passing through the axis of the cage.

By that time the hooks have assumed a radial position and are held there by the shoulders or stops e'. As the partition P-- and rib d become further inclined by the rotation of the cage the stock slides to the rib and thence over the horns --RR, which latter with the aid of the hooks e-e allow the stock to gradually or gently pass to the opposite side of the compartment and at the same time opening up the stock and throwing it into such positions as to allow the dye-liquor to efiectually permeate the same.

For the treatment of some kinds of stock or garments the ribs d--d alone will effect the desired purpose, but in the majority of cases the horns RR are essential, and by the employment of the hooks e-e the efliciency of the machine is materially enhanced. The form of the hooks and the means for sustaining them in their operative positions are susceptible of modifications and I therefore do not wish to be limited in that respect.

One of the modifications is illustrated in Figs. 4 and 5 of the drawings, in which the hooks e are of the form of claws fixed at their outer ends to a longitudinal bar gwhich is pivoted to the outer ends of the braces hh pivoted at or near the centers of their lengths to the heads of the cage. The hooks or claws e pass through sheaths or guides 'ifixed in the periphery of the cage and have their free ends protruding inside of the cage. To the ends of the vat are secured two stationary cams j and j'-, one of which is above the axis of the cage and the other below said axes and both concentric thereto. The upper cam j is at such a distance from the axis of the cage as to cause the inner end of the brace -h to ride thereon, the brace being forced into said position by the weight of the material under treatment pressing on the hooks e-e-- which forces the latter outward. The engagement of the brace h with the cam prevents the hooks -e from withdrawing from the cage and sustains said hooks in an approximately radial position inside of the cage orln a position similar to that of the hooks shown in the upper part of Fig. 2 of the drawing As the hooks or claws eenter the vat A the outer end of the brace --h comes in contact with the top of the lower cam 7- and is thereby tilted so as to cause the hooks e to be drawn nearly out of the cage and thus guard to a great extent against the catching of stock on the ends of the hooks dnrlng the movement of the stock through the dyeliquor. As the hooks emerge from the vat the upper cam j-- restores the teeth to the1rm ward projecting positions.

With the described machine raw-stock can be treated more carefully during the dye ng process than by hand, and in quantities limited only by the size of the cage or drum.

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

1. In combination with the vat, the rotary cage divided into longitudinal compartments and longitudinal ribs in the compartments extending from the axis of the cage toward the periphery thereof and forming at the latter throats for the passage of the material 1n process of being dyed as set forth.

2. In combination with the vat, the rotary cage divided into longitudinal compartments, longitudinal ribs in the compartments extending from the axis of the cage toward the periphery thereof, and horns projecting from the ribs part way toward the periphery of the cage as set forth.

3. In combination with the vat, the rotary cage divided into longitudinal compartments, longitudinal ribs in the compartments extending from the axis of the cage toward the periphery thereof, horns projecting from the ribs part way toward the periphery of the cage, and hooks projecting inward from the periphery of the cage, asset forth.

4. In combination with the vat, the rotary cage divided into longitudinal compartments, horns projecting from the central portion of the cage part way toward the periphery thereof, hooks pivotally supported at the peripheral portion of the cage, and braces sustaining the hooks in their inward projecting position above the vat as set forth.

In testimony whereof I have hereunto signed my name this 9th day of November,

LEONARD WELDON. [L. s.] Witnesses:
