CORPORATION OF NEW YORK DYEING APPARATUS Application filed September 3, 1930. Serial No. 479,492.

This invention relates to apparatus for impregnating fibrous material with dye or other liquids by injection.

Injection dyeing apparatus and an in ection needle containing an open groove are the invention of Henry E. VanNess, described in his U. S. Patents Nos. 1,577,884, 1,734L,4L55, 1,584,335 and 1,606,196. The VanNess injection dyeing apparatus has been extensively used for carrying out the Vanr ess method of yarn spotting described in his Patent No. 1,456,344.

The principal. object of the present invention is to provide means for utilizing the VanNess injection apparatus for solid dyeing of a package of yarn. The invention provides an automatic machine for this purpose which has advantages over the ordinary apparatus for solid dyeing in eeonomizing the amount of dye used, avoiding a straining of the dye, and in facilitating perfectly even dyeing of the whole mass.

\Vhile the primary object of our invention is to produce a machine for solid dyeing,

5 several features of the invention may advantageously be used in yarn spotting machines.

In our invention, we have departed from the arrangement shown in the VanNess dyeing machine patents, Nos. 1.577884, 1,584,- 335 and 1,606,196, by providing for thrusting the injection needles into the mass of yarn by a movement of the needles instead of a movement of the mass. By this change, We are enabled to operate simultaneously upon different surfaces of the mass and in particular to thrust injection needles into opposite surfaces, thus dyeing a portion. of the mass twice as deep as that which can be dyed when the needles are stationary. This enables us to dye a wound mass by thrusting the injection needles into its opposite ends, which tends to rroduce more rapid and even dyeing than can be obtained by radially-positioned needles.

Another feature of our invention consists in completely confining the mass of yarn. during the injection. This enables us to apply an even pressure to the whole mass at the time of the injection, which tends to prol mote the evenness of the dyeing.

Our invention may best be understood from a detailed description of a practical dyeing machine involving ail the abovementioned features of our invention, as well as other features hereinafter referred to. Such a machine is illustrated in the accompanying drawings, in which:

Fig. 1 is a plan view of the machine;

Fig. 2 is an end elevation of the machine;

Fig. 3 is a front elevation of the machine;

Fig.4 is an enlarged section taken on the line 44 of Fig. 3;

Fig. 5 is an enlarged vertical section showing the injectors in operative relation with a mass of yarn supported in the workholder;

Fig. 6 is an enlarged plan view of the guideways;

Fig. 7 is an enlarged section showing the mechanism for imparting rotary movement to the injectors and the passageways leading from the rod to the injectors; and

Fig. 8 is an enlarged end elevation of the mechanism for imparting rotary movement to the injectors and showing the relative positions of the outlet openings.

The yarn dyeing machine illustrated in the drawings has a frame comprising a T- sha-ped table top or plate B supported on end frames B1, B2 at its front corners and a leg B3 at its rear corner. On the plate are mounted a fixed workholder W, and two sets of injectors J, having injecting needles J2, held in carriers J3 which are movable to thrust their needles J2 into a mass of yarn C in the holder W through different surfaces thereof. The injector carriers J 3 have surfaces which contact evenly with the surface of the yarn mass C into which the injector needles J2 are inserted, and the carriers J3 are so formed that they cooperate with the workholder W completely to enclose the mass of yarn C whentheir needles J 2 have been thrust into the mass.

In the form illustrated, the workholder W consistsof a horizontal open-ended cylindrical casing having afixed lower part VVQ vmounted on a pedestal W3 secured to the plate B and a hinged upper part or cover 4 which may be tipped back to permit the insertion of a mass of yarn C and locked in closed position by a spring latch 6 after the mass has been inserted. The injector carriers J3 have the form of discs fixed on the ends of rods J 4 slidably mounted in bear ings J6 secured to the plate B at opposite ends of the workholder YV with their axes aligned with that of the workholder, so that the carrier discs J3 may he moved axially towards and away from the open ends of the workholder 'W. The diameter of the carrier discs J3 is such that they just fit within the workholder so that they may cooperate with the workholder completely to enclose a cylindrical package of yarn C therein, as.

clearly shown in Fig. 5. The injectors J project from fiat surfaces of thecarrier discs J3 which correspond to the flat ends of a cylindrical yarn package C in the holder 1V, so that they come into complete contact with the ends of the package C when they are moved into the position shown in Fig. 5. The injectors illust 'ated consist of nozzles J7 and needles J2 having open grooves and are thus substantially like the injectors shown in Van Ness Patent No. 1,577 ,884. It is, however,not essential to use this specific form of injector. The machine provides for automatic oper ation of the injectors J to effect solid dyeing of a cylindrical yarn package C in the holder WV. Automatic power-driven means are provided for moving the injector carriers J3 simultaneously towards and away from the yarn C to thrust their needles J2 into the yarn G and withdraw them therefrom. WVith V the insertion and withdrawal means are combined means for causing an angular movement of the injector carriers J3 after each withdrawal, so as to insert the needles J2 successively into adjacent portions of the mass. \Vith the insertion and withdrawal means is combined also an automatic control for a power-driven pump P which is operated to force dye into the yarn C through the injectors J after each insertion of the injectors.

The means for causing the inward and outward movements of the injectors J comprises a power-driven pulley J8 on a longitudinal shaft J9 mounted in bearings J10 on the top of the plate B, and connected by bevel gears J 11 with a short transverse shaft J12 which,

through spur gears J14, J15, drives a countershaft J17, on which are fixed oppositely positioned eccentrics J18, whose straps J19 are connected by rods J21 with levers J22, whose lower ends are pivoted to the end frames at J24. The upper ends of these levers carry yokes J25 connected to cross-heads J 26 containing rotatable studs J27 which connect with the outer ends of the rods J 4 upon whose inner ends the injector carriers J3 are mounted so that oscillation of the levers J22 causes reciprocation of the rods J 4 and the injector carriers J3 on them. Manual movement of the injectors J is provided for by introducing a clutch J28 betweenthe driving pulley J8 and the shaft J 9, and providing a hand crank J29 on the countershaft J17.

T 0 permita dwell of the injector carriers J3 at the inner ends of their strokes, the studs J27 are connected to the rods J4 through springs J31 which serve to permit a slight inward movement of the upper ends of the levers J 2-2 after the inward movement of the rods J a has been stopped by contact of the injector carriers with the ends of the package of yarn C in the holder This inward movement of the power-driven levers J 22 during the dwell serves to compress the springs J31 and thus to cause them to urge the rods J4: and injector carriers J3 inward to compress the yarn package C confined by them and the workholder V7.

The means for causing an anguiar movement of each injector carrier J3, after the withdrawal of its needles J2 from the yarn mass C, includes a ratchet J34 secured to each injector carrier J3, and a pawl J 35 carried on a frame J36 rotatably mounted on the injector carrier J3 and having a detent J37 extending into a guide slot J38 which is shaped to cause a slight rotational movementof the frame J36 and pawl J35 during the latter part of the outward stroke of the injector carrier J3 after the needles J2 have been withdrawn from the yarn C.

The injector needles J2 in the two opposite carriers J3 are placed out of line with each other, in order that there may be no chance of bringing the points of any two needles J2 into contact with each other, in case the needles are inserted slightly more than half way into the mass C. T o preserve this spaced relation between the needles J2 of the two carriers J3, the guide slots J 38 are so arranged that the simultaneous angular movements of the carriers J3 which occur on each withdrawal are in the same direction, so that the rela ve position of the needles J2 of the two carriers J3 is not changed by such angular movements.

A power-driven pump P is utilized to force limited quantities of dye through the injectors J of the two carriers J3 under equal pressures on each insertion of the injectors. The pump P is driven by power applied to a constantly rotated pulley P2 at the rear of the machine. This pulley P2 is connected through a punch-press clutch P3 to a short transverse crankshaft P4 under the plate 13 at the rear of the machine. The crank P5 on this shaft is connected to the piston P6 of the pump P. The punchpress clutch P3, and consequently the operation of the pump P, is controlled by a cam P7 on the transverse countershaft J17, which engages rod P8 just as the needles J2 have entered the mass C to cause one complete rotation of the crankshaft P4 in which the pressure stroke of the pump P occurs during the dwell of the injectors J permitted by the resilient connection between the rod J-l and the levers J22, and while the springs J31 are applying pressure to the confined yarn mass C. The liquid discharged by the pump P is conducted through pipes P9 which enter the bearings J6 of the rods J4, and communicatewith the injectors J through bores J l0 in the injector carriers J3 and bores J ll in the rods J l. Such communication is provided by radial holes J42 in the rods which are positioned to communicate with the ends of the pipes P9 when the rods J4 have been moved inwardly and in any angular position of the rods.
