DYEING APPARATUS.

Application filed Apri1 8, 1926. Serial No. 100,486.

This invention relates to dyeing apparatus and the like, and aims to provide means for impregnating predetermined parts of an ab-.

sorbent mass in the liquid.

A particular object of the invention is to provide a machine for spotting yarn while the yarn is wound in a mass of the type customarily known as a cone of yarn.

A device embodying the invention is especially adapted for impregnating predetermined parts of a cone of yarn with a. liquid such as water or an aqueous dyeing solution which does not spread readily in fibrous material, although certain features of the invention may be applied also when 'a rapidly spreading liquid such an alcohol dyeing solution is used.

' Particular objects of the invention'are to inject liquid simultaneously at closely spaced points of the portion of the mass to be dyed, to inject liquid into separated portions of the mass in such manner that a portion of larger volume receives more liquid than a portion of less volume, and to insure the penetration of a substantial amount of the liquid into the part of the mass close to the core on which it is wound. In addition the invention provides an improved holder for a cone of yarn.

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. l is a plan view;

Fig. 2

provided with. a base plate B which may be supported at about the height of an ordinary work bench by means not shown in the drawings. On the plate B are mounted a pump P and a. workholder W. In the opis a side elevation of the pump showing parts sectioned on the line 2-2 of eration of the machine the pump draws liquid from a reservoir, .not shown in the drawings, and forces it into predetermined portions of a cone of yarn on the work-holder through injectors J, J mounted on a header H fixed to the cylinder of the pump.

The pump P has a vertical cylinder P whose bore 1 is closed at its lower end by a plug P- containing a drain opening P communicating with the valve controlled drain pipe P extending through the plate B. The piston P of the pump is driven from a shaft P mounted on the lower side of the plate 15 and driven through a punching press clutch so that it ma be given a single revolution when desired y the operator. The piston is connected 'with'a crank P on the shaft P by meansmf a lever P and a connecting rod P 9. The rod P may be attached at different points of the lever P to vary the length of the stroke of the piston.

The inlet opening P of the pump cylin- \der is controlled by a check valve P which may be located in an intake pipe P connected to the opening P The. intake pipe P leads from a reservoir for the liquid dye (not shown) which may be located below the platejB.

The outlet opening P of the pump cylinder communicates directly with the header H which is mounted on the cylinder.

The header H contains two crossingbores H H (lne end of the bore H communicateswith the discharge opening 1? of the pump while the other end is closed by a plug H. A. check valve H seated in the bore H prevents the returnof liquid from the header to the pump during the up-stroke of the piston to the pump. The ends of the bore H are closed by plu s H", H, the latter of which is adjustable or a purpose hereinafter explained. The bore H is rovided with two lateral openings H H in which are mounted the injectors J and J.

The injector. J comprises a triple nozzleagainst the front surface of the header H. In an enlarged bore in the front portion of the body J is located a chuck J containing three longitudinal bores J whose outer ends form the discharge openings of the nozzle J To permit contraction of the inner portions of the bores J in 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 three bores J, and transverse slits J. The chuck J is retained in the body J 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 three projecting collars J" which are thrust into the 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 ends of the collars J Each of the needles J has a solid rear end portion J which is clamped in the inner portion of one of the bores J of the chuck 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 its collar J" may be varied.

The needle J has a pointed front, whose apex J is on the axis of the needle. The needle contains an open longitudinal groove J which extends from the portion of the needle crossing the bore J, as nearly as possible to the apex J The injector J is identical with the injector J except that in the form shown its needles J have axial bores J extending through their rear portions J instead of having solid rear portions like the nee dies J The injector needles which have been described are not claimed herein as they form the subject matter of my divisional ap lication, filed March 14, 1927, Serial %o. 175,081.

The work holder W comprises a carriage 'W carrying a standard W in which a shaft W is rotatably mounted. 0n one end of the shaft W is a cone holder WV adapted to carry a cone of yarn C by engagement with the card-board core 0 on which such a cone is ordinarily wound.

' The cone holder W engages the core C of a cone of yarn only near its ends, thus leavinga free space inside the core. The cone holder has a rod W of materially less diameter than thecore C of a cone of yarn.

carrying at its outer end an adjustable plunger W having a frusto-conical head W for engaging the core of such a cone at or near its smaller end. -At the inner end of the rod answer W is a gripping member W for engaging the larger end of the core. The member W has a threaded outer surface which forms a corresponding thread in the inner surface of the card-board core C when the core is screwed upon it.

The cone holder which has been described is not claimed herein as it forms the subject matter of my divisional application, filed March 14, 1927, Serial No. 175,082.

The carriage W is reciprocable in directions parallel tothe needles J J and adjustable transversely to the needles. The carriage is slidably mounted on rods W fixed on a frame W which is mounted on a transverse rod W adjustably secured in standards i 11 projecting up from the plate B: A shaft W rotatably mounted in similar standards W assists in'supporting the frame W and provides for reciprocating the carriage W on the rods W For this purpose the shaft W is provided with a gear W meshing with a rack W on the bottom of the carriage. A handle W is provided for turning the shaft W The shaft W and the cone holder W are rotated through a small are at each reciprocation of the carriage by means of a ratchet wheel W'" fixed on the shaft W and a pawl W carried by a bar W fixed to the outer ends of the rods .W Further rotation of the shaft W may be obtained by turning a hand wheel W also fixed on the shaft W.

In the use of the machine, the carriage W is first retracted to the position shown in Fig. 1 and a cone of yarn O is mounted on the cone holder W N has been adjusted in accordance with the length of the cones to be dyed, a cone may be mounted on the cone holder very quickly and easily as it is necessary only to slip its core .over the rod W and then screw the larger end of the core upon the threaded member W until the inner end of the core is brought into firm contact with the head W. The carriage is then moved towards the injectors by turning the handle W until its movement is arrested by an adjustable stop W This causes the neodles J J to penetrate the yarn and forces the collars J into the outer portionof the yarn so as, to compress it above the outer ends of the needles, as shown in Fig. 3. The piston P of the pump is then given a single reciprocatory movement which forces liquid previously drawn into the cylinder of the pump through the header H and the injectors J, J into the portion of the cone of yarn immediately surrounding the needles of the two injectors. The carriage W is then returned to the position shown in Fig. 1. The pawl and ratchet WV, W cause aslight rotation of the cone C during the latter part of this movement. The operation is then repeated until two separated zones C C of the cone of yarn are completely saturated with the dyeing soly spaced points, so that the dyeing may be effected by means of the solution which does not spread readily, for example, an aqueous dyeing solution. Such a solution may be evenly distributed throughout the depth of the mass. This is accomplished by the compression of the outer portion of the mass surrounding the needles by means of the collars J which prevents an excess of liquid in the outer portion of the mass, and by extending the needles so that the outer ends of their grooves J reach substantially to the surface of the core of the mass. To accomplish this it may be necessary tolet the needles project so far that their apexes J enter the core C as shown in Fig. 4, or

pierce the core, as shown in Fig. 3. This can be done without injury to the needles, owing to the fact that the cone holder W leaves a free space within the core into which the points of the needles may project.

A substantially-uniform saturation of the yarn in the two zones dyed is obtained by forcing a greater quantity of liquid into the zone C which has a larger diameter and consequently a larger volume than the zone C The difference in the quantities injected into the two zones is obtained by giving the liquid a freer passage to the grooves of the needles J than to those'of the needles J It will be noted that the liquid may enter the grooves of the needles J directly through the axial bores J 22 in the rear ends of these needles, while to enter the grooves of the needles J the liquid must pass through the slot J" in the chuck so as to enter the grooves J 21 through the transverse bore J. The flow of liquid to the injector J may be further restricted to the exact extent desired by means of the adjustable plug 'H, as clearly indicated in Fig. 4.
