DYEING APPARATUS.

Application fled January 12, 1928. SerialNo. 246,131.

This invention relates to dyeing apparatus, and aims to provide means for dyein different parts of an absorbent mass with 'fierent colors.

A particular object of the invention 1s to provide a machine for spotting yarn while the yarn is wound in a mass, and to produce bands of different colors around such a mass, each band extending from the outer to the'inner surface of the mass.

The invention may best be understood by a detailed description of a practical machine embodying it. Such a machine is shown in the accompanying drawings, in which Fig. 1 is a plan view with the b'ase plate partly broken away;

Fig. 2 is an enlarged longitudinal section taken on the line 2-'2.of Fig. 1;

Fig. 3 is a horizontal section taken on the line 33 of Fig.4.; and t I Fig. 4 is a transverse section on the linea -4 of Fi 1. I Y

Th machine shown has a base plate B which ma be supported at about the height j '26 of-an or inary work bench by means not shown in the drawings. On the base plate B is mounted a pumping deviceP and a work holder W. In the operation of the machine, the pumping device draws difierent' colored dyes from a plurality of separate reservoirs,

T, T, T, T, and forces limited quantities of the difi'erent colored dyes into separate portions of a cone of am on the work holder W'.

'Therpumping. evice P includes a cylinder 3 block P containing a plurality of vertical, bores P, P P P all of WhlCh are closed at their lower ends except for small drain openings P, communicating with valve-controlled drain pipes P extending through an opening'in the plate B. The pistons P, P P, P of the pumping device are driven from a shaft P mounted on the lower side of the plate B and driven thro. gh a pumping press clutch so that it may be given a single revolution when desired by the operator. n the shaft P is a crank P connected by means of a connecting rod P to the free end of a lever P fulcrumed on a bracket, P mounted on the cylinder block P The lever P" is connected by alink P to a slide P" mounted on a vertical rod P, which isslidable in two bearin s P formed on the cylinder block P The plstons are connected with the slide P so as to be reciprocated thereby.

The length of the stroke of the slide. P may be varied by attaching the up er end of the connecting rod P in any one .o the number of holes P in the lever P. The lengths -of the strokes of the individual pistons may also be adjusted. In the form illustrated, the pistons P and P are directly connected to the slide P, so that their strokes are the same lengph as that'of the slide, while the pistons P, are connected to the slide in: such away as to allow for a-regulatable amount of lost motion. For this urp'ose, the iston rods P ofthe pistons P, are slida le in holes in the slide P and are provided with fixed collars P below the slide, and adjustable collars P and P 'above the slide. It is a parent from this arrangement that the stro e of the piston P is less than the stroke of the slide P by the amount by which the distance between its collars P and P exceeds the thickness of the slide. Thus with the adjustment shown in Fig. 4, the piston P has a stroke shorter than'that of the pistons P and P, which move with the slide, and longer than that of the piston P.

. The inlet openings P 3 P P P of the cylinders are connected by pi es 1? to the separate dye reservoirs T, T", T which may be located below the plate B. glach of the pipes P contains a check valve An outlet opening P located near the bottom of each cylinder, communicates directly with one of a plurality of injectors J, J, J J d attached to one side of the cylinder block.

Each injector comprises a double nozzle J and two needles J 2 fixed in the discharge openings of the nozzle. The nozzle J has a body J 3 on the rear end of which is a threaded stem J which is screwed into anip'ple J 5 attached to the cylinder block P over one of the outlet openings P The stem J con- ..tains a nozzle bore J 6 which is the intake opening of the nozzle J In an enlarged bore in the front portion of the body J 3 is located 3. Chuck J containing two longitudinal bores J whose outer ends form the discharge openings in the nozzle J To permit com ression of the inner portions of the bores J 1n order to grip the needles therein, the rear portion of the chuck contains a diametrical slit J at the inner end of which is a transverse bore J extending across the two bores J and a transverse slit J The chuck J is retained in the body J 3 by a nut J which is screwed on the front end of the body and engages the chuck J so as to force the conical inner end J of the chuck against a conical seat in the body. The chuck J has at its outer end a projection J which is thrust intothe mass to be dyed when the mass is brought into operative relation with the injector. On the outer end of the nut J is an annular projection J lying some. distance behind the outer end of the projection J Each of the needles J has a solid rear end portion J which is clamped in the inner portions upon the bores J by screwing the nut J inward. As the shaft of the needle is of uniform diameter, it may be gripped at any point by the chuck, so that the distance which it projects beyond the end of the projection J may be varied. The needle has a pointed front end whose apex J is its axis. The needle contains an open longitudinal groove J 21 which extends from the portion of the needle crossing the bore 13 as nearly as possible to its apex J The work holder WV comprises a carriage -W carrying a standard W in which a shaft W is rotatably mounted. On one end of the shaft W is a cone holder W adapted to carry a cone of yarn C by engagement with the card-board core C on which such a cone is ordinarily wound.

The carriage Vv is reciprocatable in directions parallelto the needles J J and adj ustable transversely to the needles. The carriage is slidably mounted on rods VV fixed on a'frame V which is mounted on a transverse rod adjustably secured in standards VV projecting up from the plate B. A shaft WV rotatably mounted in similar standards W assists in supporting the frame Y9 and provides for reciprocating the carriage V on the rods For this purpose, the shaft W fiis provided with a gear W meshing with a rack l/ 15 on the bottom of the carriage. A handle W is provided for turning the shaft The shaft W and the cone holder W are colors. After a cone has been placed on the cone holder \V, the carriage is moved towards the injectors by turning the handle V until its movement is arrested by an adjustable stop W. This causes the needles of each injector to penetrate the yarn. The slide P is then given. a single reciprocatory movement which forces the different colored dyes previously drawn into the bores of the cylinde'r block through the separate injectors into the portions of the cone immediately surrounding the needles of each injector. The carriage W is then returned to the position shown in Fig. 1, the pawl and ratchet W", VV' causing a slight rotation of the cone C during the latter part of this movement. The operation is then repeated until four separate zones C C (1 C, each extending completely around the cone and extending from its outer to its inner surface, have been saturated with the four differently colored dyes. I

Substantially uniform saturation of the yarn in each of the four zones and uniform Width of the four zones is secured by forcing a greater quantity of liquid into the zones which are of larger diameter and consequently of larger volume. The quantity of dye injected into each zone of the cone is measured'by the volume of the portion of one of the bores below its piston when the piston is at the upper end of its stroke. From the connections between the pistons and the slide P already described, and the setting of the collars P and P of the pistons P, P, it is apparent that the smallest quantity of dye is injected into the zone C nearest the smaller end of the cone. A larger quantity is injected into the zone C while still larger quantities are injected into the zones (1 and C This arrangement has proved satisfactory in practice, but it is apparent that, if desired, the machine may be arranged to inject different quantities of it into the zones C and C by connecting the piston P to the slide P in the same way as that in which the pistons P and P are connected thereto.
