Patented Dec. 5, 1939 UNITED STATES PATENT- OFFICE 5 Claims.

The invention relates to random dyeing machines for yarn, and has'for its object to provide means whereby a strand of yarn is scil lated across a dye spray and the yarn intermittently dyed whereby spaced zones of color are placed thereon so that when the yarn is woven into cloth or an article it will have variegated color, or pattern.

A further object is to provide a means whereby the speed of operation of the strand of yarn across the spray may be varied for shortening or lengthening the zones of color on the strand.

A'further object is to provide a random yarn strand dyeing machine comprising a reciprocating yarn strand guide, positioned in relation to a second stationary guide whereby when it is reciprocated the strand of yarn will pass through a dye spray above a collecting receptacle.

A further object. is to provide a means controlled by the reciprocating shaft for intermittently cutting off the supply of dye to the nozzle, which dye is under pressure, thereby producing a random effect by having the reciprocity guide stationary or itmay be used in conjunc- 5 tion with reciprocating guide.

A further object is to mount the yarn guide adjustably on a reciprocating shaft, thereby allowing the same to be adjustedfor limiting the time the strand is subjected to each spraying 30 action for varying the length of the dyeing zones thereof.

A further object is that by leaving the reciprocating guide stationary, the random effect could be produced by the intermittent spray 35 without the use of the reciprocating guide. My

invention can be used with or without the reciprocating guide or the valve controlling the supply or that both might be used inconjunction.

With the above and other objects in view, the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise 45 embodiment of the invention may be made within the scope of what. is claimed without departing from the spirit of the invention.

In the drawings: Figure 1 is a side elevation of the machine. 50 Figure 2 is an end elevation of the machine. Figure 3 is a vertical transverse sectional view taken on the line AA of Figure 1.

Referring to the drawings, the numeral I designates the frame of the machine and 2 a shelf carried thereby. Mounted on the shelf 2 is a at its threaded adjusting points ll.

motor 3 having a drive shaft 4. The drive shaft 4 has mounted thereon a drive pulley 5, and around which drive pulley and a driven pulley 6, a belt 1 extends. The driven pulley 6 has eccentrically mounted thereon a wrist-pin 8, which 5 may be adjusted into any of the apertures 9 for varying the stroke of the connecting rod I0. Apertures 9 are at different distances from the center of the pulley, hence it will be seen when the removable wrist-pin 8 is placed in anyof the 10 apertures, the stroke of the connecting rod l0 will be varied.

The range of movement of a stroke may be also varied by shortening the connecting rod l0 Connecting rod I0 is hingedly connected at I2 to a reciprocating rod l3, which extends through guides I4 carried by the side'of the dye collecting receptacle l5, and terminates at its forward end in a guide carrying rod l6 on which the yarn 20 guide I! is adjustably mounted by means of a set screw l8. The yarn guide I1 is carried by the sleeve 19. The strand of yarn 20 is fed through the machine from the package 2| adjacent the machine and extends upwardly and through a' double pigtail guide tensioning loop 22, and thence upwardly and transversely over the machine through the yarn guide I1, and across the dye collecting receptacle l5 to a stationary yarn guide wheel 23 and thence to a 001- lecting yarn package roll 24. As the yarn is fed across the receptacle 15, it is laterally oscillated for exposing sections or zones thereof to the action of a dye spray 25 from a spray nozzle 26, which is disposed above the receptacle l5, and the excess dye passes through the opening 21 in the receptacle l5, and may be conveyed back to the source of dye supply in any suitable manner. The dye is supplied to the nozzle 26 through a supply pipe. 28 which may lead to any suitable source of supply and the dye is placed under pressure by a conventional form of pump 23, which is driven by'the motor shaft 4. The pump is supplied with dye through the pipe 30. It will be noted that as the yarn guide "is oscillated, a spray of dye will be impinged on the yarn, and

as the yarn crossing the receptacle is moved into and out of the path of the spray, interrupted sections thereof will be impregnated with the dye. m

If. desired the dye may be conserved by providing an intermittent sprayin g operation through the medium of a valve 3| carried by the supply pipe 28, which valve'is controlled by a lever 32 av ng a link connection 33 with an adjustable collar 34 mounted on the reciprocating rod l3, and the timing of the opening and closing of the valve may be adjusted through the medium of the collar 34, whereby the spraying operation will take place as the yarn moves into the zone of the nozzle operation. The random effect may also be produced without the reciprocating motion.

It is obvious the device can be used in connection with any kind of winding machine where yarn is transferred from one package to another and that the shaft l6 and branch pipe 35 may be extended to take care of a plurality of similar devices. For purposes of illustration only one device is shown.

The supply pipe is also provided with a regulating valve 36 for regulating the amount of liquid or dye allowed to pass to the nozzle, hence it will be seen there is a complete and positive control of the dyeing operation.

From the above it will be seen that a random dyeing machine is provided which is simple in construction and one wherein a strand of yarn may be dyed with spaced zones of color of varying length so that when the strands are woven into a fabric a variegated design is formed. Slight changes may be made in my construction of invention without departing from the broad scope of my invention.

The invention having been set forth what is claimed as new and useful is:

l. A random dyeing machine for movable strands, said machine comprising a stationary spraying nozzle for spraying dye, means for longitudinally moving the strands through the spraying zone at an angle to the nozzle, a stationary thread guide to one side of the nozzle, a reciproeating thread guide to the opposite side of the nozzle, means for reciprocating the last named thread guide, said reciprocating thread guide forming means whereby the thread is intermittently moved through the spraying zone of the nozzle beneath the nozzle and laterally on the stationary thread guide as a pivotal point, and a dye collecting receptacle beneath the nozzle and strand.

2. A device as set forth in claim 1 including means whereby the strokes of operation of the reciprocating thread guide may be varied.

3. A device as set forth in claim 1 wherein the means for reciprocating the thread guide comprises a reciprocating shaft on which the thread guide is mounted, means for reciprocating said shaft, said last named means including means whereby the stroke of the reciprocating shaft may be varied.

4. A device as set forth in claim 1 including a dye supply pipe leading to the nozzle, a reciprocating shaft on which the reciprocating thread guide is mounted, a control valve carried by the pipe, means carried by the reciprocating shaft and controlling the valve whereby the spraying action will take place when the thread is beneath the nozzle and means for reciprocating the reciprocating shaft.

5. A- random dyeing machine for single strands, said machine comprising a downwardly extending nozzle, a dye receiving receptacle beneath the nozzle, means for feeding a strand beneath the nozzle and means for oscillating a strand beneath the nozzle at an angle to the nozzle and laterally through the zone of dyeing.
