DYElNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 416,854, dated February 24, 1891.

My invention relates to dyeing-machines;

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 construct 'a dyeing-machine for dyeing skeins of yarn,

wherein the yarn may be supported upon rollers arranged above the liquid inthe tank, and may be alternately lowered into the liquid and raised therefrom, the time in which the yarn is in the liquid being preferably a great deal longer than the time in which it is lifted clear of the liquid, or substantially clear of the same, and exposed to the action of the atmosphere. Furthermore, when the yarn is raised clear of the liquid the rollers which support it are caused to rotate, whereby the skeins may be rotated so as to insure every portion of the yarn being treated alike.

In the construction employed by me the yarn is hung on a series of parallel rollers, which are so constructed as to keep the several skeins apart, and the adjacent portions of two skeins of yarn on different rollers are caused to travel in the same direction, so as to avoid any possibility of tangling.

Referring to the drawings, Figure 1 is a side elevation of a dyeing-machine embodying my invention, with the lower portion of the machine made in section. Fig. 2 is an end elevation of my improved dyeing-machine, with the dye-vat made in section. Fig. 3 is a side elevation of automatic mechanism whereby the yarn may be supported within the liquor a great deal longer than the time it is supported out of the liquor, and Fig. 4 is a perspective View of the cam shown in Fig. 3.

A is a dye-tank, and may be made of metal or wood in any suitable manner. As shown, it is rectangular, and is provided with a superstructure or frame-work B. At each end of the dye-vat and guided in the frame-work B is a carriage G, in which are journaled a series of rollers D, which extend the length of the vat A and are formed with grooves, as shown in Fig. 1, whereby the various skeins of yarn hung thereon will remain separated.

Serial No. 347,983. (No model.)

the carriages C, or one end at least is so removable as to permit the placing'of the yarn upon said roller. The various rollers D are connected together at one end by spur-gearing (1, so that the adjacent rollers rotate in opposite directions for the purpose of insuring the adjacent yarn traveling in the same direction.

Arranged at the upper part of the machine is a shaft F, carrying at each end a crank f,

to which are hinged the links K, connecting at the lower part with the carriages C. By rotating the shaft it is seen that the carriages and the rollers D will be raised and lowered with respect to the vat for the purpose of dipping and removing the skeins supported upon the rollers. This shaft F'may be rotated by means of a pinion H, which gears with a spur- Wheel' G upon the "shaft F. The pinion H is secured upon a shaft I, which may be driven by a belt-pulley J or otherwise, as desired.

Secured to the shaft F is a sprocket-wheel M, about-which passes a sprocket-chain m, the other end of which rotates a similar sprocket-wheel N, secured to a shaft upon which another sprocket-wheel M is secured. Pivoted to the axis of the sprocket-wheel M is an arm L, carrying at its other end a sprocket-wheel M similar to the one last described, and about these two sprocket-wheels passes an endless sprocket-chain m. The free.

end of the arm L may be guided in the curved guideway Z, if desired, permitting a given amount of vertical movement to the sprocketchaiu. This sprocket-chain m, it will be seen, is constantly traveling, and when the car riages O are raised a sprocketwheel E on the end of one of the rollers D is brought into contact with the traveling sprocket-chain, and thereby imparts a rotary movement 'to the several rollers D. The loose connection of the arm L prevents binding, and also enables the sprocket-chain to be maintained in connection with the sprocket-wheel E during a longer period. The cranks f may be adjustable, if desired, to vary the reciprocation of the carriage.

I will now refer to the mechanism which may be employed for supporting the skeins of yarn a longer time in the liquid than that occupied while they are raised clear of the liquid.

Referring to Fig. 3, the pinion II is secured to the shaft I as before, and upon said shaft is a clutch S, adapted for connection with a belt-wheel J. Secured to the belt-wheel is a worm N, which meshes with a worm-wheel O, which latter wheel, through the gearing I rotates a cam Q,havin g the cut-away portion (1. (Best shown in Fig. 4.)

R is a lever for operating the clutch S, and is pulled against the cam Q by a spring r. \Vhen in the position shown in Fig. 3, the rollers D are in their lowest position. As the wheel J rotates the cam Q is gradually rotated until the cut-away portion (1 permits the lever R to be drawn to the left of the spring 1', forcing the clutch S into contact with the wheel J. A further motion of the wheel .I then rotates the shaft I, and through the gearing II G rotates the crank fand lifts the carriages and their rollers into their upper positions.

The length of the notched part (1 with reference to the other portions governs the relative time that the carriages and the rollers are held in an elevated position with respect to the time occupied in their lowest. position. The proportion of the gearing should be such that as soon as the cranksfare in their lowest position the clutch should be thrown out of action, so that for one revolution of the shaft 1 the cam Q should make a portion of a revolution equal to the length of the cutaway portion 'lhecarriages and their rollers may be counterbalanced by means of weights 0, connected to cords c, passing from the carriag s over suitable pulleys arranged above the free ends of the rollers and each connected with said weights 0.

I do not limit myself to any particular mechanism for accomplishing this result as to the time of elevation and depression of the carriages and rollers, as it may be modified in various ways and still accomplish the same result. The various details of the machine may be modified without in the least 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
