To all whom it may concern.:

Be it known that I, JOHN MOUNTGOMERY COLLINS, engineer, a subject of the Queen of Great Britain, and a resident of the city of Glasgow, Scotland, have invented certain new and useful Improvements in and Connected with Machinery for Dyeing and Scouring Yarn, (for which a British patent has been granted, No.14,507, dated August 11, 1892,) of which the following is a specification. This invention relates to machinery for dye lng and scouring yarn, and it has for its ob- Ject to make a simple,lcheap, and effective machine for that purpose.

In order that my said invention may be properly understood, I have hereunto appended three explanatory sheets of drawings, wherein- Figure 1 is a front elevation of the machine. Fig. 2 is an elevation of one end of the machine and Fig. 3 is an elevation of the other end. Figs. 4, 5, 6, 7, 8, 9 and 10V are detail views. Fig. 11 is a side view of the driving wheel of the friction gear. Fig. 12 is a plan view of the yarn carrying poles. Fig. 13 is a side view of the central supporting carrier or plate. Fig. 14 is a section of the plate or carrier on the line :z3- Fig. 13. Fig. 15 is a front View; Fig. 16 a longitudinal section on the line g/-y (Fig. 15) and Fig. 17 isa side elevation of the ferrule for the ends of the Fig. 18 is a front view and Fig. 19 a side elevation of a socket spindle. Fig. 20 is a front view and Fig. 21 aside elevation of a dierent construction of ferrule for one end of a pole; and Figs. 22 and 23 are, respectively, front and side views of a ferrule for the opposite end of the pole. Fig. 24 is a section of the friction driving gear for revolving the poles of the machine. Fig. 25 is a side view of the driving wheel of the friction gear.

Reference is made to the drawings whereon the same reference letters wherever repeated indicate similar or like parts.

The machine consists of a dye vat or vessel a, on the ends of which are fitted two vertical frames b, c. The frames support, in bearings, a horizontal shaft d, which extends the full length of the machine and has on it two sprocket/or chain wheels d d2. Passed over the chain wheels are chains e e', which are connected to two bars f one at each side of the machine. The bars f are fitted in carriers g, g', which slide in slots h, h, h', h', ln the vertical frames b, c. The carriers g are made with bearings in them through which pass spindles t' having sockets t" on their inner ends (see also Figs. 18 and 19). Fitted in these sockets, of which there are, preferably, three in each carrier g, one on each spindle t', are the left hand ends of the yarn carrying poles which are hereinafter more particularly described. Fitted on each setof spindles t are pinion wheels lc which gear with one another. The central pinion of each set also gears with a cog wheel lo (Figs. 1 and 24) which is mounted loosely on a spindle 7c3 (Fig. 24) fitted in each carrier g. Two ratchet wheels l, Z (see also Figs. 5 and 9), which are pinned together, are also fitted loosely on the spindle k3. The ratchet wheels have their teeth cut in opposite directions. A cog wheel m (see also Figs. 4 and 9) is fitted loosely on the outer end of each spindle 7c3, and these cog wheels gear with vertical racks -m carried in brackets m on the frame b..

Mounted on a stud fitted at the back of each wheel mis a double pawl n (see front and side views, Figs. 7, and 8) the one arm n" of which catches in the ratchet teeth of the ratchet wheel Z, while the other arm n2 catches in the teeth of the other ratchet wheel Z.

A stud n3 (see Figs. 6, 7, and 8) on the pawl n passes through a slot n4 in the wheel mand is capable of being moved backward and forward therein so as to change the action of the pawls. To keep the stud n3 in its various positions a spring 0 is used. This spring is pinned to the front of the wheel m and is bent as shown at Fig. 4, so that its end,.which has a wave-shaped head of with a cut or recess o2 in the crest of the wave, bears against the stud n3. When the stud n3 is placed in the recess o2 (as shown at Fig. 6) the pawls are thrown out of gear, Whereas, if the stud is moved along theinclined plane at one side or other of the head, one or other of the arms n', n2, of the pawl, is thrown into gear with one or other of the ratchet wheels l, Z.

The overhead shaft d and chain wheels d', d2, are caused t0 partially turn backward and IOC forward so as to alternately, raise and lower the carriers. g, g', with their gearing and the yarn carrying rollers j, into and out of the dye vat or vessel d, by means of a crank p which is connected by a lever p to one end of a second leverp2 which latter is fulcrumed, at its other end, p3 in a bracket p4 fitted on the right hand end of the dye vat a.. (See Fig. 3.) The lever p2 has on it a studp5 (see Fig. 10) which is provided with a small friction roller. The roller on the stud runs in the groove q of the heart-shaped cam g which is carried on'a short shaft r. The cam shaft y7 has also on it a toothed wheel r which gears with and is turned bya worm Wheel/112 keyed on a shaft s which is carried in bearings s' s2. The shaft s is revolved by means of band pulleys t. v Y

t is a bearing bracket for the outer end of the shaft fr.

t2 is the bearing for the inner end.

u are stays.

y 'y' represent hanks of yarn. To lift the yarn out of the vat at any time, the cross shafts fv, o are provided. These shafts are carried in bearings in each frame b, c and are capable of being revolved by means of a long overhead shaft fw, which has worms w' at each end. These worms gear with pinions w2 on the shafts c, fu'. Fitted on the shaft w is a grooved pulley w3 on which is fitted an endless rope 104.

are drums or barrels fitted on the cross shafts 1;,Uand fitted to these drums are four chains a2 two at each end of the machine. These chains are provided with hooks at their lower extremities, which, when it is desired to lift the yarn out of the vat, are caught on the barsf and, then, by pulling the rope 104 and turning the wheel w3, the drums are caused to revolve and wind up the chains, so raising the barsf, and the four carriers g, g with their yarn carrying rollers up out of the Vat. WVhen it is not desired to raise the yarn up out of the vat the chains 0c are slung, as shown, on to the stays u. j

Instead of making the polesj, in one piece as usual, they are, under this invention, made in two or more parts 7" j2 as shown at Figs. 1 and 12. The ends of each part or half pole are provided with ferrulesjs, which are shown to an enlarged scale at Figs. 15, 16, and 17. These ferrules which are, or may be, hollow so as to t on the ends of the poles,are made with recesses,b at each side and at right angles to the recesses, a solid bridge piece b2 is eft.

b3 b4 are two raised parts or projections. With this construction of ferrule no matter how the poles are turned about or interchanged the ferrules b will always lock into each other as the projections b3 b4 can always be fitted into the recesses b. Then the ferrules are locked together the projections b3 b4, of one ferrule, catch on and hold against the bridge piece b2 of the other and vice versa.

The left hand or driving ends of the poles j are fitted into the socket spindles t'. These spindles, as shown to an enlarged scale at Figs. 1S and 19, are made, in their socket part i', with a central raised projection c' and four recesses c2 which appear in plan, see Fig. 18, somewhat like a St. Georges cross.

c3 are triangular shaped projections left in .the metal. As will be seen no matter how the poles are shifted about or interchanged the projections b3 b4 of the ferrules will always lock into two of the recesses c2 and the central projections c of the socket spindles will always lock into the central space left between the projections b3, b4,of the ferrules.

Figs. 2O to 23 show modified constructions of ferrules. The ferrule a2 Figs. 2O and 2l is 'fitted on one end of a half pole and the fer'- rule 0,3 Figs. 22 and 23 on the other end. The ferrule co2 is made with a central projection co4 and the ferrule a3 with a corresponding recess d5. When the half poles are locked together the projection on one part tits into the recess of the other. driving spindles would also, in this case, be made with central ribs or projections which would lock or key into the recesses of the ferrules. This construction of ferrule is not so good as the construction hereinbefore described as the poles can only be locked to- The sockets of the gether in one way t'. e., when the ferrule a of 95 one pole comes opposite the ferrule of a,s of another. Should the poles be so turned about that the ferrule a2 (or as) of one pole,

comes opposite the ferrule a2 (or as) of another, then, of course, they will not lock together.

The sectional poles, of which there are, preferably, three sets'at each side of the ma.- chine, are supported at either end by the carriers g, g which slide up and down in the side frames b, c of the machine and in the center by supporting carriers g2.

The carriers, g, g', g2, are connected t0- gether by the longitudinal bar f. The ceutral carrier g2 may be made with a. sleeve ga through which the bar f passes. The carrier g2 may be capable of sliding on the bar, so as to suit different lengths of sectional poles, and be clamped in place by means of pinching screws g4. Stays g5 may connect the plate g2 with the lifting chain collars h2. The central carrier g2 has three holes g6 (see Fig. 13) for the reception of the abutting ends of the half poles which are so fitted together that thc ferrules interlock within these holes. The end carrier g has also three holes or sockets for the reception of the ferrules lat the ends of the half poles jz. The ferrules at the driving ends of the half poles j' are fitted in the socket spindles 11, which pass through and revolve in backwardly extending bearings jls (see Fig. 12) cast on the carrier g. Trough shaped guards j (see Fig. 13) maybe cast on the plates g, g', g2, just below the holes or bearings as the case may be. Projections j may be cast on the plate gto guide it in its vertical movements within the slot of the frame c. `The central bearingj1s of the plate g'serves in conjunction with the bearing l* of IIG- the spindle k3 of the friction gear (see Fig. 24) as a guide for that plate as it moves up and down in the slot of the frame b.

m2 (Figs. 1, 13, and 14) are hollow brass or other rods for keeping the yarn stretched. These rods are fitted to snugs m3 (Fig. 14) on extension plates m4 attached to the guide plates g, g', g2. The rods are locked tothe plates by means of pins m5 which are passed through holes in the ends of the rods and in the snugs. The rods have holes 'm6 at one end for the purpose of allowing the dye liquor to circulate through them.

The action of the machine is as follows:- The revolutions of the shaft s, operate the cog wheel r and cam q, and this cam, as it revolves, gives an oscillating motion to the levers 192,19', and crank p, as a consequence the chain wheels d', d2, from which are suspended the two sets of sectional poles j with their banks of yarn, are partially revolved backward and forward. As the setsof poles are so suspended by the chains e, e', passing over the wheels d', d2, that they balance each other, it follows, that at each partial turn of the wheels d', d2, in one direction the yarn at one side of the machine will be lowered or dipped into the dye liquor, while the yarn at the other side, will be raised up out of or partially out of the dye liquor; when the wheels partially turn in the opposite direction, the d1 pping action is reversed.

I t will bev seen that with this machine the action is continuous, the yarn at one side being dipped while that at the other is being lifted up and vice versa.

As the carriers g and g are raised and lowered the cog wheels m, run up and down the racks m', and, as a consequence, are revolved. The revolutions of the wheels m, cause, according as the pin n3, is placed to one side or the other of the niche or recess o2 in the head o of the spring o, one or other of the arms of the pawl n to gear with and revolve one or other of the ratchets Z, l. The revolutions of the ratchets cause the cog wheel k to revolve and through it also the train of pinions k. The revolving motion of the pinions is communicated by the spindles t' and sockets i to the poles jon which the yarn is hung. When the arm n on the paw] yn is made to gear with the ratchetl the pinions lo and poles j are made to revolve in one direction, while,when the arm n2 is made to gear with the ratchet Z the pinions and poles are revolved in the opposite direction.

It is sometimes desirableto revolve the poles, for a short period, very quickly. This can be etected by moving the pin n3 into the recess 02 so as to throw the arms of the pawl n out of gear, when this has been done a handle ,a (see dotted lines Fig. 1) is fitted on the squared cuter endof one of the spindles t' and the train of pinions quickly revolved by hand.

As it is possible that the yarn lmay sometimes be caught and held when being turned, and as it is, when so caught likely to break poles.

some part of the machinery I provide a friction driving gear to, in such cases, turn without moving the poles or unduly straining the yarn. vThe gearis shown at 'Figs 24 and 11.

It consists of the wheel m which is made with a hollow boss m7 through which passes a tightening screw m8. This screw works in the spindle 7c3. Interposed between the ratchets Zand Z and the tooth driving wheel la are two leather or other soft washers o4 o5 and a metal washer o6. The wheel mis revolved as it travels up and down the rack m as hereinbefore explained and the wheel la drives the train of pinion wheels k for revolving the As all the gear is loose on the spindle k3 it follows, as a consequence, that by slackening the screw m8 the friction between the wheel lo and washer 05 can beso reduced that said wheel lo will not be turned orbe turned with very little power by the main4 driving wheel m and also if the screw m8 is tightened up the friction and power will be increased. By turning the screw m8 the gear can be so adjusted that should the yarn catch the wheel lo will slip and not be turned by the wheel fm. The poles j ,7'2 may be covered or cased with brass or other suitable metal.

For the purpose of preventing the banks of yarn, when being turned on the poles, from coming in contact with the carriers g, g', g2,

short cross bars or guards 112 made of wood or metal are fitted in brackets v3 cast on or secured to the carriers. These rods prevent the yarn working to the ends of the poles. Of course, if so desired, each pole j may be made in three or more sections, and, in this case, a corresponding number of supporting carriers g2 would be litted on the bars f.

The vat a may be divided longitudinally into two compartments by a partition, and, in this case, one compartment may contain a dierent dyeing liquor from the other, so that the yarn at one sidemay be dyed a dierent color or shade from that at the other.

The complete machine and vat a may be mounted on wheels if so desired, for convenience in moving it from one part of the dye house to another.

By making the machine with two sets of susper ded balanced poles the cost of construction is reduced, less power is required to drive the machine, the yarn is dipped oftener, and the machine does not require to be made so strong or so heavy as at present. The action is also continuous, for, when the yarn on one side is being raised out of the liquor in the vat the yarn at the other side is being dipped.

Having now fully described my invention, what I claim, and desire to secure by Letters Patent, is Y 1. In yarn dyeing and scouring machines the combination with a vat, of two side frames fitted to the ends thereof and supporting an overhead shaft with pulleys thereon and chains passing over said pulleys from which a set of yarn carrying poles is suspended at IOO IIC
