- the clutch is of the type commonly used in punching machines and is therefore not described herein in detail. It is so set that it releases the crank shaft P23 on each revolution when the crank P10 and piston P22 are at their lowest points. Consequently, whenever the controlling lever P37 is raised, the pump makes one complete comprec sion stroke, one complete intake stroke, and then stops.

Application September 15, 1925, Serial No. 56,420. Renewed July 28, 1931 18 Claims.
This invention relates to apparatus for impregnating parts of an absorbent mass with a liquid, and more particularly to apparatus for spotting yarn by dyeing portions of a wound mass of i the yarn.
Machines for carrying out the method of dyeing masses of yarn or other absorbent material, by injecting limited quantities of dye into predetermined portions thereof, are described and claimed in my co pending applications Serial. No.
-tendant upon manual operation and to reduce the labor cost of yarn spotting. Specific objects the invention are to provide in a machine for dyeing an absorbent means for making simultaneous injections of dye at a plurality of pol s of the mass under equal pressures, means for adjusting the pressure under which the dye is injected, means for supplying dye automatically when the mass iu in position to he dyed, automatic means for indexing or successively setting different portions of the mass in position to be dyed, and automatic means for stopping the machine when the dyeing of 'a predetermined part or" the mass has been completed.

The yarn spotting machine illustrated in the drawings has a frame comprising a plate B supported on legs B1 and B2. On the plate are mounted a pump P, having a dye reservoir T conerected therewith, and a work-holder W. Under the plate B is suspended the driving mechanism which includes a main driving shaft S (on one end of which is mounted the continuously driven which may be connected with the driving shaft through gears P34 and P35, a clutch P33, and a cam wheel. W 25 for operating the work-holder W which is mounted in alinement with the crank shaft P23 but is independently driven from the main shaft. During the operation of the machine a cone C of yarn is supported on the workholdcr W and is moved thereby so as to bring successive portions of its surface adjacent to a bank of injectors J mounted on one side of the casing of the pump P. As successive portions of the injectors.
this conduit.
1 on crank shaft P23.
' automatically operated to withdraw dye from the reservoir T and force it into the cone through A curved plate A hinged to the plate B serves as a guard for enclosing the driving mechanism.
The pump P has a vertical cylinder P1 whose bore P5 is closed at its upper end by a cylinder head P3. In the lower end of the bore is a piston P22 which is reciprocated on rotation of the crank shaft P23 by means of a crank P and. a connecting rod P24. Leakage around the piston is prevented by a packing ring PS0. The inlet opening P8 of the pump is located slightly below the upper end of the pump cylinder and is connected with the dye reservoir T by means of a conduit PS containing a ball check valve P7 to prevent the return of dye to the tank through The pump outlet is controlled by the slide valve members P20 and P21 mounted on a valve stem P25 located in projection P66 at one side of the pump cylinder. The valve stem P25 is reciprocated by means of an eccentric P28 Outlet openings P and P16 in the wall of the pump cylinder communicate through an intermediate vertical bore P13, the horizontal passages P17 and P18, and the vertical passages J13 with a bank of outlet openings P50 arranged in two vertical rows in the outer wall of the valve casing. Each opening is threaded for the insertion of an injector J (hereinafter described) or a plug J17. The passages P17 and P18 are normally closed by the valve members P20 and P21, but are simultaneously opened when the cut out portions P26 and P27 in the valve stem register with them.
It is apparent that on each down stroke of the piston P22 the pump cylinder will be filled with dye from the reservoir T up to the level of the top of the intake opening P8, and that on the up or compression stroke of the piston the dye in the cylinder and the air trapped in the upper portion ofthe cylinder will be placed under pres sure and forcibly delivered to the injectors J in the outlet openings P50 when the valves P20 and P21 open the passages P17 and P18. The eccentric P28 is so positioned with respect to the crank P10 that the pump outlets are opened during the latter part of the compression stroke of the piston.
In order that the quantity of dye ejected from the pump on each compression stroke may be V J varied, the valve stem P is connected with the eccentric strap surrounding the eccentric P28 by means of a turn-buckle P29. The adjustment of this turn-buckle determines the exact point in the compression stroke of the piston at which the slide valves will open. The setting of the turnbuckle is indicated by a pointer P30 secured to the slide valve on a scale P31 on the slide valve casing.
i In order that the pressure under which the dye is supplied to the injectors may be varied, the pump cylinder is'connected to the dye tank T by means of a by-pass or a relief conduit P44 containing an'adjustable valve P41. As the pump is mechanically driven so that each compression stroke of the piston is'made at the same speed, the pressure which will be obtained in the pump cylinder at each compression stroke is determined by the setting of the valve P41. Since the passages P17 and P18 are simultaneously opened by the slide valves P20 and P21, the pressure developed in the cylinder is simultaneously applied to all the outlet openings and to all the injectors J which may be mounted therein.
In order that the pump may be automatically operated whenever the cone of yarn C is in position to be dyed, the pump crank shaft P23 is con nected to the gear P35 continuously driven by the gear PS4. on the drive shaft S by means of the clutch P33 which causes the crank shaft P23 to make one complete revolution on each raising of the controlling rod P37 of the clutch. The clutch is of the type commonly used in punching machines and is therefore not described herein in detail. It is so set that it releases the crank shaft P23 on each revolution when the crank P10 and piston P22 are at their lowest points. Consequently, whenever the controlling lever P37 is raised, the pump makes one complete comprec sion stroke, one complete intake stroke, and then stops.
To facilitate changing the dye used. in the machine and to prevent liquid from standing in the machine when it is not in use, a valve controlled drain-pipe P47, communicating with the bottom of the bore P13, is provided. Through this pipe any liquid which, after the use of the machine, remains in the pump cylinder bore P5, in the passages connecting this bore with the injectors. or in the tank T, may be drained out.
The dye reservoir T is provided with a cushion ring T2 for supporting a bottle of dye in inverted position and providing a liquid seal for retaining the dye in the bottle and maintaining a con stant dye level in the reservoir T. Besides facilitating the changing of the dye, this arrangement has the advantage of keeping the ingredients of the dye well mixed as the dye in the bottle is agitated by the bubbles of air which pass up into it whenever dye is drawn from the tank T.
The injectors J, of which any desired number maybe inserted in the apertures or outlet openings P50, may consist merely of nozzles, that is, devices providing openings through which liquid may be discharged in a predetermined direction. The specific injectors shown in the drawings con-- tain in addition to such nozzles, means for opening narrow passages into the mass of yarn.
As shown in the drawings, each injector comprises a nozzle J1 and a needle J2 fixed in. the discharge opening of the nozzle. The nozzle J1 has a body J3, on the rear end of which is a threaded stem J4 which is screwed into one of the apertures P50. The body J3 contains an axial bore J5, which is the intake opening of the nozzle, and is also provided with a flanged portion J6 adapted to seat against the side of the projection P66 of cylinder P1. The outer portion of axial bore J5 is enlarged to receive the chuck J7 containing an axial bore J S which forms the discharge opening of the nozzle. The
chuck J7 is held in place by a nut J9 screwed on the front end of the body and engaging the chuck in such manner as to force the conical part J10 against a conical seat in the body. The outer end of the chuck is tapered so that when the needle J2 is inserted into a mass of yarn that portion of the chuck will also be introduced into the mass to prevent the injected liquid from spreading over the surface of the mass. In operative position the outer face 01' flanged end of nut J9 rests firmly against the surface of the yarn to further prevent undesirable spreading of the injected dye.
The needle J2 has its rear end inserted in the axial bore J8 of the chuck J7, being so retairled by screwing the nut J9 inwardly to concone of yarn which is toward the i1 tract the chuck. Since the shaft of the needle is of uniform diameter it may be gripped at any point by the chuck. Consequently the di tance which the needle projects beyond the nut J9 may adjusted to allow for the desired penetration of the needle into an absorbent mass.
Th needle J2 terminates in a point J11, the apex of which is on the axis of the needle. tending substantially the entire length of the needle and communicating with the discharge opening J is an open longitudinal groove J12 which is adapted to permit lateral egress there from throughout substantially the entire length of the portion of the needle projecting beyond the end J3 of the chuck J7. By varying the arrangement of the injectors and the plugs J17 in the apertures P50, the needles J2 are caused to be inserted in different portions of the cone of yarn, as shown in Figs. 12 and 13.
The mass of absorbent material to be dyed is supported in'such manner that the injector needies J2 will enter the mass substantially simultaneously and to the depth, so that all the parts of the mass with which the needles are in contact will be operated upon the same time and in the same manner. This mode of operation coupled with the fact that the dye is forced through all the injector needles simultaneously under the pressure assures uni" formity of result. The mass of absorbent material to be dyed, Whether yarn or otherwise, may have any convenient form, but is herein shown as a wound mass of yarn of frustro-conical form, indicated at C, and conventionally termed a cone of yarn.
The cone of yarn is supported on a coneshaped form or mandrel W3 mounted on an upright shaft W1 positioned equidistant from the two vertical rows of injector needles. The shaft W1 is inclined toward the injector needles so as to present the yarn surface C1 perpendicularly to them. a result of this arrangement the vertical rows of injector needles are equidistant from the points on the yarn surface C1 corresponding to or opposite them, thus assurlug simultaneous penetration of the yarn mass by the injector needles. The mandrel W3 is provided near its bottom with a roughened surwe which serves to grip the core on. which the yarn is wound to prevent rotation of the core about the mandrel. upper portion of the mandrel is covered by a wooden form which is held in place by a screw W5. T mandrel is detachably secured to the shaft W1 by means of a set screw W6.
The mandrel W3 which cons ti, support or work holder is lYlGll l to more to pump to hi i yarn C -ato and out of cative 1 injector use as J2 the cone of operative n with the injector l latter are re flanged ends of the nuts 0 yarn, and the or 1' tion, the pump is through he needles into in Figs. 12 13. mandrel or y is also mounted to cause the surface 01 or eetor needles to move transversely of the needles so that a fresh portion of the yarn mass may be positioned opposite the needles. In order that the yarn surface C1 may be moved transversely of the axes of the injector needles J2, the shaft W1 which supports the mandrel W3 and the cone of yarn is rotatably mounted in the inclined bearing W2 formed in the standard W7.
The yarn support W3 is moved into and out of operative relation with the injector needles by means of the cam wheel W25 which is loosely mounted on one end of the shaft P23 and on stud W9 extending inwardly from one of the legs B2. In the periphery of the cam W25 is a groove W14 in which travels a roller W13 mounted on a stud W12 depending from the under side of a carriage W8 on which the standard W7 is supported and to which it is adjustably secured by the cap screws W69. The carriage W8 is slidably mounted on the plate B and is guided in its inand-out movement-s relatively to the injectors by the guides W11 rising from the plate B. The cam groove W14 is of such shape that as the cam wheel W25 makes one complete rotation, the cone of yarn is moved into contact with the injector needles and withdrawn therefrom. When the'cone of yarn has been moved into contact with the injector needles, it is held in that position to permit the dye to be injected into the yarn mass. For this purpose the cam groove W14 is provided with-a dwell W which extends around substantiallyone-quarter of the periphery of the cam wheel W25.
The cam wheel W is driven from the main shaft S:--a pinion W48 fixed on the shaft S meshes with a gear W49 connected with a clutch W43 mounted on a shaft W52 journaled in brackets depending from the plate B. On one end of the shaft W52 is fixed a pinion W44 which drives a gear Wet secured to the inner end of the cam wheel W25. The clutch W43 is of the same construction and mode of operation as the clutch P33. When the clutch controlling rod W62 is raised the clutch W43 operates to communicate the rotation of the gear W 49 through the shaft W52 to the cam wheel W25. The clutch W43 is manually closed at the beginning of the operation of the machine by means of the handle W51 fixed on the forward end of a rod W 59 mounted transversely under the plate B. The rod W is operatively connected with the clutch controlling rod W62 through the arms W27. To insure in-' stantaneous stopping of the rotation of the shaf W52 when the clutch W43 is opened by the depression of the rod W62, a spring-pressed plunger W55 acts as a brake on the disk W56 fixed on the shaft W52.
While the dwell W10 'of the cam groove W14 is in engagement with the roller W13 holding the cone of yarn in contact with the injector needles J2, the piston P22 is actuated to force the dye through the injector needles and into the yarn mass. For this purpose a cam surface W 57 formed on one of the sides of the dwell groove W10 is adapted to engage with a roll W58 carried 7 by the lower end of an W56 fixed on one end of a rod W59 journaled in the machine frame and extending longitudinally under the plate B. On the other end of the rod W59 is fixed an arm W60 pivotally connected by the link W46 and lever such that the crank shaft P23 makes four revolutions while the cam wheel W25 makes one revolution. Consequently when the clutch P33 is operated to connect the crank shaft P23 with the main shaft S by reason of the oscillation of the rod W59 through the engagement of the roller W58 by the cam surface W57, the crank shaft P23 makes one complete revolution to actuate the piston P22 and the valve stem P25 while thedwell W10 of the cam groove W14 is in engagement with the roller W13 holding the cone of yarn in contact with the injector needles.
The yarn support W3 is rotated or indexed to position fresh portions of the yarn surface opposite the injector needles by means of a ratchet wheel W15 secured to the lower end of the inclined shaft W1 and resting on the inclined surface W29 which forms the bottom of a ratchet housing in the top of the standard W7. A cover W22 secured to the top of the standard W7 completes the housing in which the ratchet W15 is located. The ratchet W15 is actuated by means of a pawl W20 pivoted in the cutaway middle portion of a rod W19 slidingly received in a sleeve W18 located on one side of the standard W7. A leaf spring W21 secured to the rod W19 presses the pawl W20 into engagement with the teeth W41. A spring-pressed plunger W23 housed in the plate W22 acts as a brake on the ratchet W15.
When the carriage W8 is moved forward toward the pump P to bring the cone of yarn in contact with the, injectors, the forward end of the rod W19 encounters an adjustable stop W26 threaded in the upper end of an upright W24 rising from the plate B. The engagement between the forward end of the rod W19 and the stop W26 arrests the forward movement of the rod W19 while the carriage W8 is completing its travel to bring the cone of yarn into full operative relation with the injector needles. This additional forward travel of the carriage W8 and the parts connected with it while the rod W19 is arrested causes the next succeeding tooth on the ratchet W15 to be brought into engagement with the pawl W20. On the return movement of the carriage W8 and the parts connected with its rear end of the rod W19 encounters a stop screw W28 mounted in a bracket W27 secured to the end of the plate B. The rear end of the rod W19 encounters the stop W23 before the carriage W8 completes its return travel from the pump. The further outward travel of the carriage W3 and the parts connected with it while the rod W19 is arrested causes the pawl W20 to turn the ratchet W15, whereby the cone of yarn is indexed through an arc corresponding to the angular distance between the ratchet teeth W41. If it is desired to vary the circumferential distance between the spots to be dyed in the cone of yarn, the number of ratchet'teeth W41 will be varied accordingly.
When the machine is set in operation by turning the handle W15 in a clockwise direction to lift the rod W62 which controls the clutch W43, the machine continues to run (unless manually interrupted as hereinafter explained) until the yarn dyeing operation is completed. To hold the clutch controlling rod W62 raised to maintain the machine in operation the upper end of the rod W62 is loosely connected with one end of a bar W53 pivotally mounted in the upright W54 rising from the plate B. The other end of the bar W53 is adapted to be held depressed, to keep the rod W62 raised, by the lower end of a lever W30 pivoted in the upright standards W32. The compression spring W33 acting on the upper end of the lever W30 tends to force the lower end thereof toward the bar W53. A handle W31 secured to the upper end of the lever W30 provides means whereby the bar W53 may be released to stop the machine at any desired point in its cycle of operations.
The bar W53 is automatically released to stop the machine, when the dyeing operation of the whole cone has been completed, by the engagement of a block W38 with the plate W34 secured to the upper end of the lever W 30 while the cone of yarn is being retracted on the completion of the dyeing operation. The block W38 is pivotally mounted on the outer end of a rod W36 slidingly supportedin a sleeve W35 mounted on the plate W22. A leaf spring W39 yieldingly holds the block W38 in its normal position. On the inner end of the rod W36 is a bevel faced block W37 which is spring pressed into the path of rotation of the bevel face pin W17 projecting radially from a collar W16 fixed on the shaft W1 and resting on the center of the ratchet wheel W15. A pin W41 projecting upwardly from the rod W36 travels in the slot W42 in the sleeve W35 and thereby prevents the rod W36 and the blocks W32 and W38 from turning.
When the cone of yarn to be dyed is placed on the yarn support the radial pin W17 occupies a position immediately beyond the block W37, that is to say, immediately to the left of the block W37, viewing Fig. 1. The yarn support rotates in a counter clockwise direction so that when the last undyed portion of the cone of yarn is opposite the injector needles the bevelled face of the pin W17 is in contact with the bevelled face of the block W 3'2, thereby holding the block W38 in position to strike the outer curved end of the plate W34 as the yarn support moves toward the injector needles. When the bevelled face of the block W 33 strikes the plate W34 the spring W39 yields and permits the bevelled face of the block W38 to travel past and in contact with the plate W34 without actuating the lever W30. As the yarn support completes its inward movement towards the injector needles the block W38 passes beyond the inner end of the plate W34. The spring W39 thereupon restores the block W38 to its normal position. Then as the yarn support is retracted after the dyeing operation, the straight face of the block W33 encounters the inner curved end of the plate W34 and forces it and the upper end of the lever W30 outwardly against the action of the spring W33, thereby disengaging the lower end of the lever W30 from the bar W53 and permitting the spring W47 to depress the clutch controlling rod W62 and stop the machine.
The mode of operation of the improved yarn spotting machine may be briefly recapitulated as follows:The desired arrangement of the injector needles J2 is effected by inserting the needles in the appropriate apertures P50. The unoccupied apertures are then closed by the plugs J 17. The pressure under which the dye is to be forced through the injector needles into the yarn mass is controlled by regulating the valve P41 in the by-pass P44. The quantity of dye to be injected through the needles into the yarn mass is determined by the position of the openings P26 and P27 in the valve stem P25 relatively to the piston P22. The positions of these various parts having been determined experimentally the cone of yarn C to be dyed is placed on the yarn support W3, the straight face of pin W17 resting against the straight face of block W37, as shown in Fig. 1. The operator then starts the machine by turning the handle W51 in a clockwise direction to lift the clutch controlling rod W62 to permit the clutch W43 to connect the constantly rotating gear W49 with the cam wheel W25. The upward movement of the rod W62 depresses the outer end of the bar W53 so that the spring W33 may force the lower end of the lever W30 into engagement therewith to hold the rod W52 raised throughout the yarn dyeing operation. The rotation of the cam wheel W causes the carriage W 8 and the cone of i yarn mounted thereon to be moved toward and retracted from the injector needles J2. While the dwell W10 of the cam groove W14 is in. en gagement withthe roller W13 the cone of yarn is held in operative relation with the injector needles to permit the dye to be injected into the yarn mass. During the time that the roller W13 is in the dwell part W10 of the cam groove W14 the cam surface W57 connected therewith moves into engagement with the roll W58 to oscillate the rod W59 to operate the clutch P33 and there by set in operation the crank shaft P23 to actuatethe piston P22 and the valve stem P25. As the carriage W8 completes its in-andout movement toward and from the injector needles, the sliding rod W19 causes the pawl W20 to turn cone of yarn by its operative en agement with the teeth Wal of the ratchet wheel W15 By the time that the last undyed portion of the cone of yarn has been positioned opposite the injector needles the radial pin W17 has moved into en gagement with the block W37 thereby moving and holding the block W38 in position to engage with the plate W34. On this forward movement of the cone of the block slides over the plate W34 inoperatively. As the cone of yarn is retracted from the injector needles for the last time the straigh side of the block W38 encounters the inner end of the plate W534, and forces it and the upper end of the lever W outwardly, thereby disengaging the lower'end of the lever from the outer end of the bar W 53 and permitting the spring W47 todepress the clutch controlling rod W62 and stop the machine.
