PATENT THOMAS O. DILL, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO THE T. C. DILL MACHINE COMPANY, OF SAME PLACE.,

APPARATUS `FOR DYEING.

SPECIFICATION forming part of Letters Patent No. 586,117, dated July 13, 1897. Application filed March Z8, 1896. Serial No. 585,226. (No model.)

To all whom it may concern.:

Beit known that I, THOMAS O. DILL, a citizen of the United States, residingin Philadelphia,Pennsylvaniaiave invented certain Improvements in Dyeing-Machines, of which the following is a specification.

The object of my invention is to construct a dyeing-machine to which can be applied the ordinary vat now in common use and in which the vat is entirely independent of the agitating and lifting mechanism.

A further object of my invention is to so construct the mechanism that the yarn can be raised vertically out of the vat and then carried over to one side thereof and suspended, so that the operator may remove the dyed skeins and load the sticks with yarn to be dyed; anda still further object is to so construct the mechanism that the machine will be automaticthat is, after the sticks are loaded the machine will automatically carry the yarn into the vat, agitate it therein for a certain length of time, then lift it out of the vat and suspend it at one side until thrown into gear again by the operatorwhereby the machines can be set by the man in charge to the length of time required for a certain dye or a certain yarn, so that the mistakes due to the carelessness and inattention of the hands in the dye-house are entirely avoided.

In the accompanying drawings, Figure l is a side view of my improved dyeingmachine Fig. 2 is a plan view. Fig. 3 is a longitudinal sectional view of the vat with the mechanism in elevation. Fig. 4 is a side view, partly in section, showing the dyeing-frame suspended at one side of the vat. Fig, 5 is a side view, drawn to an enlarged scale, of the pawl-and-ratchet mechanism. Fig. 6 is a View looking in the direction of the arrow, Fig. 5. Fig. 'F is a side view of the pawl-andratchet mechanism, showing the pawls in dif? ferent positions. Fig. 8 is a sectional view of the pawl-and-ratchet mechanism. Fig. 9 is a diagram view of the pawl-and-ratchet mechanism. Fig. 10, Sheetl, is a perspective view of the ratchet-wheel- Fig. 1l ,Sheet 4, is a detail view showing the method of clamping the sticks to the yarn-frame. Figs.

l2 and 13, Sheet 5, and Fig. 14, Sheet l, are views of details of the invention.

A is the base, made in the present instance of planks, and mounted on this base is the vatA,cont-ainingthedyeingliquid. Secured to the base at each side of the vat are frames A2, carrying the mechanism by which the yarn is suspended and agitated.

B is the driving-sleeve, loose on the shaft B and clutched thereto by the clutch mechanism B2, which is operated by the lever B3. (Shown clearly in Fig. 3.) On the sleeve B is a sprocket-wheelb, around which passes the drive-chain. On the shaft B is a pinion b', engaging with a gear-wheel h2 0n the eccentric-shaft B4. This eccentric-shaft carries two eccentrics c c', adapted to sockets in the eccentric-rods O and C', respectively.

The eccentric-rod O is connected to an arm d of a hell-crank lever D, while the eccentricrod C is connected to an arm d of a bell-crank lever D. Both bell-crank levers are loosely hung on the shaft E, which is adapted to bearings in the frame A2. This shaft E extends across to the frame A2 on the opposite side of the vat and is adapted to the bearings therein.

On the shaft E at each side of the vat is an arm F. These arms are keyed to the shaft and are pivot-ed at f to arms F, which support the yarn-frame.

Pivoted to the arm F at j", some distance above the pivot f, is a bar F2, which is slotted at f2 to allow for the free movement of a pin ,f2 on the arm F, and on the end of the bar F2 is a pin f4, adapted to a camway a in a block a', secured to the frame A2, so that when the arm F lifts the yarn-frame it will removethe yarn-frame from the vat'in a vertical line untilthe yarn is clear of the vat, andthen it will swing it over to one side, as indicated in Fig. 4.

The arms F and bar F2, as well as lthe mechanism connected therewith, are dupli cated on the opposite side of the machine, and one set 0f arms works in unison with the other.

It will be noticed that while the arms are duplicated the mechanism for operating the that all the intricate mechanism is at one place and within easy reach of the man in charge of the machine.

ln some instances the shaft E may be lengthened and a second shaft maybe placed alongside of the vat shown, and a duplicate set of arms can be mounted on the shaft, so that two or more dye-vats and yarn-frames may be used at the same time.

Keyed to the shaft E is a double ratchetwheel G, (shown clearly in Fig. 10,) and engaging with the ratchet-teeth of this wheel are pawls carried by the bell-crank levers D D', one set of pawls acting to agitate the yarn in the dye-vat, while the other set of pawls act in conjunction with the iirst set to remove the yarn-frames from the vat and to carry them into the vat.

Referring to Fig. lO, the ratchet-wheel G has a double row of teeth on its periphery. On one row there are two sets of teeth g2 g3, beveled in opposite directions, so that the pawl that engages one set of teeth will move the wheel in one direction and the pawl engaging the other set of teeth will turn the wheel in the opposite direction. Between the two sets of teeth is a space g4, which allows the pawl e to simply work in a given space without imparting motion to the wheel. The teeth on the opposite side are arranged in substantially the same manner, and at the end of one set of teeth is a stop or lug d4, beneath which the pawl d3 rests, thus preventing it from lifting when the pawl d3 has reached the limit of movement.

The pawls d2 and d3, as shown in Fig. 8, are carried by the bell-crank lever D' and engage with the ratchet-teeth g on the wheel G, Fig. l0, and when the shifting arm H is in the position shown in Fig. 8, as well as in Fig. l, both pawls d2 and d3 engage the teeth g on the wheel G in such a manner that the wheel will vibrate with the movement of the eccentric c', rod C', and bell-crank lever D'. This movement will be conveyed to the yarnframes in the vat through the shaft E and arms F F' and bar F2, so that the yarn-frames Will be raised and lowered during a given number of revolutions of the main shaft, as dictated by the time-wheel I, described in detail hereinafter.

The time-wheel is mounted on a stud t', which is screw-threaded, so that when the time-wheel I turns it is moved forward on the stud, and on the time-wheel is a lug i', which when the wheel is full out, as indicated in Fig. 6, will rest in the path of a lug 72, on the shifting arm H. This shifting arm is pivoted at 7L' to the bell-crank lever D', as indicated in Fig. 8, and has two toes h2 h3, which project one on one side of the arm and the other on the opposite side. The toe h2, when the arm is in the position shown in Fig. 8, rests upon one end of a weight J, pivoted at j to the pawl cl2, while when the arm is shifted to the position shown in Fig. 7 the toe h3 rests upon one end of the weight J pivoted at j' to the pawl d3.

Carried by the bell-crank lever D, Fig. 5, are two pawls e e', one pivot-ed on one side of the lever and the other on the opposite side. The pawl e engages with the teeth g2 on the ratchet-wheel G, and the pawl e' engages with the teeth g3 on said wheel, and on the back of the pawl e is a pin e2, which rests in a camgroove jz in the weight J, and on the back of the pawl e' is a pin e3, resting in a camgroove js in the weight J It will be noticed on referring to the perspective view, Fig. l, that the weights J J' have cam-grooves formed by projecting portionsj2j4, so that when the pin of the pawl c enters the cam-groove its bearing upon the surface j* will tend to hold the pawl e out of gear with the ratchet Gwhen the shifter-arm H is in the position shown in Fig. 5, so that the pawl e will simply work in the space g4 in the wheel G without imparting motion to the wheel, while the pawl e' will ride upon the cam-surfacej5 and will be lifted clear of the teeth of the wheel G, so that both pawls c e' are out of gear. The pawls are in this position when the yarn-frame is simply agitated in the liquid, motion being imparted to the wheel G and its shaft E through the pawls Z2 and d3, which are engaged with the wheel, as shown clearly in Fig. 8.

Hung to the bell-crank lever D', at 712, is a weighted pawl I', which engages with the ratchet-teeth on the time-wheel Iland feeds the time-wheel forward at each forward movement of the lever.

A weighted detent-pawl I2, (see Fig. 5,) pivoted to the frame of the machine at 3, prevents the return of the time-wheel, so that the time-wheel will feed forward during a certain period until its lug i" crosses the path of the lug 71. on the shifting lever H, when the said lug will come into contact with the lug on the time-wheel, and, as the time-wheel is adapted to kfixed bearings, the arm H will be shifted from the position shown in Fig. S to the position shown in Fig. 7, releasing the weight J and acting upon the weight J so that the pawls d3 and e' will be in engagement with their respective teeth on the wheel G and first one pawl will act and then the other to elevate the yarn-frame out of the liquid in a straight line x above the vat, as shown in Fig. et. At the point x the chain f5, which is attached to the shifting lever and is hooked to one of the elevating-arms, is drawn taut and the shifter will release the clutch and stop the machine, so that the yarn can drain into the tulo, and at this point the dyer can sample the yarn, if necessary.

The above movement will continue if the chain is detached until the pivot of the yarnframe is at the point Fig. 4. Then the pawls c and d2, which heretofore have simply acted as followers for the pawls e' and d3, come into play and allow the yarn-frame to lower a IOO IIO

tooth at a timeuntil the lug d4, Fig. 9, locks the pawl js, which will stop this portion of the machine. j

It will be seen by the above description that two of thepawls will lock one of the bellcrank levers to the wheel G and its shaft E, so that the yarn-frame will be simply agitated in the liquid,while two cams on one side,when the shifting arm is thrown, will raise the yarn-frame outof the liquid andcarry it to a point directly above the mechanism, and as soon as the frame passes over the center the other pawls willfallow the frame to lower to a position at theside of the vat within easy reach of the operator.

The top section M of the yarncarrying frame consists of a longitudinal bar m and cross-bar fm', and on the end of the longitudinal bar are pins m2, with which engage the arms F at each side of t-he vat. The ends of the arms Fare slotted, forming mouths for the reception of the pins, and each mouth is flared, so that the pin will readily enter, and they open to one side, as indicated in Fig. l, so that when the mechanism commences to elevate the yarn-frame the yarn is gradually turned, so as to `prevent the yarn-frame becoming disengaged. To prevent any lateral displacement,the ends of the pin are headed at one side, as indicated at Fig. 14, andrest back of projections on the lower jaw of the mouth, Fig. l.

Suspended from the section M of the yarnframe by screw-rods p p, one set at each side of the machine, are recessed bars p', adapted to receive the sticks s, carrying the skeins of yarn. Mounted above the bar p is a clampplate p2, which locks the stick to the bar by turning the nuts p3 on a screw-rod lo, Fig. 4:. A plate p4 at each side prevents the longitu dinaldisplacement of the sticks.

The bar p can be moved to and4 from the section M of the carrying-frame by means of a nut p5 on the screw-rod p, the nut p5 resting on'the cross-bar m of the section M.

Hung in the lower portion of each series of skeins is a stick s', and these sticks are held together by the lower section M of the yarn-frame, which simply consists of two recessed bars t and t', hinged together at t2, Fig. ll, and adapted to receive the ends of the sticks s. A screw s3 and nut s4 lock the bars to the stick, as clearly indicated in Fig. 3.

Secured to each side of the tank, near the bottom, are brackets a2, on which the section M' rests during a portion of the stroke of the yarn-frame as it is agitated, so that, as indicated in Fig. 3, when the yarn-frame is lowered the upper sticks s leave the yarn, allowing the dye liquor to gain access to the space between the yarn and the stick, and the yarn will pass away from the lower stick s' when the lower portion of the yarnframe is stopped by the brackets on the back, so that the liquor will gain access to the portion of yarn below the sticks. Thus the yarn is thoroughly impregnated with the dye liquor, all portions of the yarn being subjected to the liquor at each movement of the mechanism, and as the yarn is perfectly free during certain portions of the time that it is in the liquor it will not kink; but when removed from the liquor it is completely under control, being held by the two sections of the frame.

When the yarn is raised sufficiently clear of the vat, the clamp-bars t t can be removed from the sticks s and can be supported on the vat in any suitable manner until a new batch of yarn is adjusted on the upper frame and the sticks inserted within the skeins, after which the clamps can be secured to the lower sticks. It will thus be seen that the machine is automatic to a certain extent, can be readily applied to any length of vat, and the vat can be readily removed from the machine without disengaging any of the mechanism.

While I have illustrated my invention in connection with a machine for dyeing yarn, it will be understood that it may be used in connection with machines in which a vat is used and in which material is to be subjected to treatment of liquid in the bath and agitated under treatment-eas, for instance, machines for washing yarn, machines for pickling metallic plates prior to plating them with tin or other metal, duc; but my invention is especially applicable for use in machines for dyeing yarn.
