To a/ZZ whom t may concern:

'Be it known that we, AUGUST GEAEMIGER, a citizen of the Republic of Switzerland,and a resident of Cheetham, and WlLLIAM THOMAS VHITEHEAD,a subject of the Queen of Great Britain, and a resident of Radcliffe, Manchester, in the county of Lancaster, England, have invented new and useful improvements in machines for dyeing, bleaching, and otherro wise treating yarn in cop or other compact form, of which the following is a specification.

The invention has been patented in England to ourselves and others, No. 9,692, dated i5 June 12, 1889.

Our invention relates to improvements in machines for dyeing, bleaching or otherwise treating yarn in cop or other compact form and is of general applicability to machines zo in which an intermittent rotary cop carrier in conjunction With'a carrier body is employed in a liquor tank, and in Which the cops to be dyed or otherwise treated are placed on perforated injection tubes or spindles and the liquor is drawn or forced through the same by suitable means; and the objects of our improvements are, irst, to reduce fric tion between the cop carrier and carrier bod y and to increase the capacity-of the machine; 3o second, to provide means 'whereby the liquor left in the cops from boiling or mordanting can be extracted; third, to separate the air and liquor extracted from the cops by the preliminary exhaustion chamber so as to prevent the liquor from entering the air pu'mp and'to effect the return of the same into the tank free of air; fourth, to provide means whereby the machiue,on being set in motion by the attendant, automatically opens the 4o vacuum valve in connection with the preliminary exhaustion chamber and air pump, closes the same and stops the machine to permit the substitution and desired treatment of the cops; fifth, to provide means whereby the liquor is automatically supplied to the tank in certain quantities according to the number or weight of cops to be treated. We attain these objects by the mechanism illustrated in the accompanying four sheets of 5o drawings, in which Figure l, Sheet I., is a vertical section through A-B Fig. 3, Sheet Il. Fig. lX is a detached side and front View ofone of the cams on the cop carrier operating the lever arm in connection with the vacuum valve mechanism; Fig. 2, a side View of the vacuum valve detached and Fig. 3, Sheet II., a plan partly in section ot' a machine With a double disk cop carrier. Fig. 4, Sheet III., is a section through C-D Fig. 5, Sheet IV., and the 6o iat-ter a side view with liquor tank in section, and Fig. 6, Sheet IV, a longitudinal section through E-F Fig. 4, Sheet III., of a Vmachine with a cylindrical cop carrier.

Referring to Figs. l, 2 and 3, Sheets I and II, a is the liquor tank, b, b the cop carrier, c the carrier body, d the cop carrier axis, e the liquor pump of the machine.

In the tank a is employed a cop carrier, consisting of two disks b, b', suitably fixed on the axis CZ mounted in bearings a and intermittently rotated by means of spur wheel gearingf,f,f2, shafts fS and f4 and clutch f5, 75-

from the driving shaft f6 through chain f7,

sprocket wheels f8 and ft. In conjunction with the said two carrier disks 19,5, a central stationary carrier body c, bolted to the liquor tank @,is ground or by means of rubber rings 8o c fitted air tight between/the inner faces of the disks b, b. The outer faces of the carrier disksb, b are respectivelyA formed with four cop tube hole or nipple groups g', g2, g3, and g4, Which serve to receive the perforated injection tubes g on which the cops g5 to be treated are placed.

The carrier body c is formed with four chambers 71.', h2, h3, h4,.which on the intermittent rotation of the cop carrier b,b,come suc- 9o cessively into communication with each of the four groups of cop lube holes or nipples g', g2, g3, and g4, so as to permit in chamber h substitution and liquor (from boiling or mordanting) extraction, chambers h2 and h3, 95 saturation and impregnation, and chamber h4 liquor extraction of the cops.

To the top of the carrier body c is connected a pipe t', which is in connection With a pump and communicates with the chamber h, by Ioo means of which the liquor left in the cops from boiling or mordanting, (which heretofore had to be recovered) can be removed in the same machine in which they are dyed, the chamber h thus serving as a primary liquor exhaustion chamber. The carrier body c, below the liquor level in the tank a, is formed with a cavity lo, having two ports la', 7a2 leadin g respectively to the saturation and impregnation chambers h2 and h3 and the pipe lconnected thereto leading to the liquor pump e so as to subject four cop groups silnultaneously to saturation and impregnation, the liquorbeing returned into the tank a by the pump e through the pipe l.

Between the saturation and impregnation chamber h3 and the liquor extraction chamber h4, an inlet pipe m connected to a pump, not shown, is fitted thereto, which communicates wit-h a port m leadingpto the liquor extraction chamber h4.

Between the primary liquor extraction chamber 72, and the saturation and impregnation chamber h2, the preliminary or air exhaustion chamber h having ports n, is formed, which are equal in number to and in communication with the circular rows of cop tube holes or nipples in the carrier disks b, b. To the said preliminary or airexhaustion chamber h, is connected an inlet pipe n', n2 furnished with a tap 'n3 leading to an air pump, not shown,

whichv tap n3 serves to cut off .the respective connection as desired for certain colors. Into this pipe u and n2 we insert an air and liquor separator, consisting of a cylinder or casing o provided at the top and bottom respectively with air and liquor valves 0 and 02 formed on the rod oB and held against their seatings by means of a spring 04. These valves o', o2 are automatically opened, the moment before the preliminary extraction of liquor or air exhaustion from the cops takes place, by means of one or more cams p fixed to the carrier disk b operating a bell crank lever p connected by means of a rod p2 to the forked lever q pivoted to the cylinder or casing o and embracing the valve rod 08.

The side of the cylinder or casing o near the tap n3 of the preliminary exhaustion chamber h, is furnished with a chamber q which is in communication therewith and the pipo n and furnished with a perforated division plate q2, preferably concave, against which the air on rushing from the preliminary exhaustion chamber h strikes, so as to cause any liquor which it may contain to separate therefrom and descend into'the lower part and the air to ascend into the upper part of the said cylinder 0, from which the air is permitted to escape, and the liquor returned into the tank a on the valves o', o2 being opened as aforesaid.

The pipe n2 between the cylinder or casing o is provided with the vacuum valve 'n4 by means of which communication is established and cut off as required between the air pump and preliminary extractor 71., automatically as follows: In connection with the clutch f5 a shipping rod fr is employed which when pushed forward by the attendant throws the clutch f5 in gear and sets the machine in mo'- tion, the part of the clutch f5 which otherwise revolves loosely on the shaft f3 being formed with a sprocket wheel f9 to which motion is transmitted from the sprocket wheel f8 on the shaft f6 by means of the chain f7.

The shipping rod r is furnished on its upper side with a projection fr bearing against a lever r2 suspended from the casing of the vacuum valve n4 and'bearing against the stem of the latter. Below the shipping rod ris positioned alever arm t pivoted to a bracket r3, bolted to the' tank a, which lever arm t, is under the influence of a spring t Fig.` 3 and operated upon intermittently by four cams 152 which operate respectively in connection with each cop group g, g2, g3, g4. When the carrier disks b, b are at rest, the vacuum valve n4 is closed andthe free end of the leverarm t, on the point of the cam t2 belonging to the cop group next thereto, while a projection r4, provided on' the under side of the shipping rod r, bears against the front edge of the lever arm t.

When it is desired to commence the rotation of the carrier disks b, b', the free end of the shipping rod r is raised a little, so as to free the lever armtfrom the projection r4 and afterward pushed forward causing the projection 'r' to depress the lever r2 and the latter the stem of the vacuum valve n4 thus opening the valve 'n4 and the shipping rod r at the same time throws the clutch f5 in gear. The free end of the lever arm tis then caused to move down the incline of the respective cam t2 toward the disk Z), which causes the projection r4 to leave the upper side of the lever arm t, drop and position itself again against the front edge of the latter. During the rotation of the carrier disks b b', the vacuum valve n4 remains open until one of the series of cop groups has passed the preliminary exhaustion chamber h. The cam t2 of the next cop group then comes into contact with the arm t, moves it outward and causes the latter to draw with it the shipping rod rand thus close the vacuum valve n4, throw the clutch f5 out of gear and thereby stop the machine.

The liquor in the tank a is automatically replenished by means of a charging vessel uV which is in communication with the same, by means of the pipe u and with a liquor reservoir not shown, by means of the pipe u2. The charging vessel u at its lower extremity is formed with a port us which is in communication with a two way tap o having attached to its spindle a weighted lever o and slot le. ver o2 the latter being connected to a sliding rod o3 which is acted upon by one or more camsp fixed to the cop carrier disk b and establishes communication between the charging vessel u and the liquor tank a.. The cam p may be vmade adjustable in length so as to retain the communication, between the liquor tank a and the charging vessel u, open any desired period, thus supplying more or IOO IIO

less liquor to the tank a as may be required for' the number or weight of cops to be treated and to keep the liquor in the tank a always at the same level. When the cam p leaves the rod o3 the weighted lever o turns the tap t; and establishes communication between the liquor reservoir and the charging Vessel u, which latter is formed at the top with an air hole s and ball valve s which floats in a cage s2 on the liquor and closes the air hole s when the charging vessel u is full.

In order to diminish friction and insure always a good joint between the cop carrier b and its bodyc in a cylindrical machine, see Figs. 4, 5, and 6, Sheets III and IV, we form the carrier body c so as to constitute one end of the cop carrier b, against which the latter rotates, in lieu of inside the same. This carrier body c is formed with segmental chambers h, h2, h3, h4 for effecting substitution, preliminary extraction, saturation, impregnation and liquor extraction of cops similar as hereinbefore described, each chamber being respectively in communication with the conduits n', k2, m.

In lieu of forming the cop tube holes or nipples in the cop carrier bin groups, we form the same in rows, at equal distances apart, all round the periphery of the cop carrier b, a separate segmental cavity w being formed in the carrier body c for each row instead of for a series thereof, which greatlyincreases the capacity of the machine and causes the cops to be treated more effectually and uniformly.

The cop carrier b and its body c are suitably xed onto the axis d vand made adjustable thereon against each other by means of nuts d and to insure an air tight t between the same, the respective surfaces are ground together or furnished with rubber rings. l

Referring more particularly to Figs. l and 2, the operation of the machine is as follows: After the tank has been supplied with liquor, and assuming the nipple groups g', g2, g3,

` g4, on the carrier b, b are positioned respectively opposite the chambers Ik', h2, h3, h4, in the carrier body c, the nipple groups g are supplied with cops g5 previously mordanted, and the superfluous mordant extracted from the respective cops g5 by means of a suction pump (not shown) and the pipe t' connected thereto and the chamber h', which latter then communicates with the nipple and cop groups g. After the extraction of the mordant, as described, the cop carrier l), b', is set in rotation, by pushing the lever o* forward which throws in gear the clutch f5. Power is transmitted through the chain f7, wheels fifi and gearsf, f', to the disks b and b', until the cam t2 of the nipple and cop groups g', comes into contact with and moves the lever t and the latter the shipping rod r outward, `so as to throw the clutch f5 out of gear and thus limit the rotation of the cop carrier b, b lto aquarter of a revolution. At the commencement ofthe rotation of the cop carrier b, b the valve n, which when the machine is at rest is closed, is opened through the mediums r', r2 and thereby communication established, by way of tap n3, pipes n', 'n2 and vessel 0, between the vacuum pump (not shown) and the preliminary extraction chamber' h. During this first quarter of a revolution of the cop carrier b, b', each radial row of its perforations is successivelybrought in communication with the ports 'n leading to the preliminary exhaustion chamberh and thus the nipple and cop groups g', fora short period subjected to the action of a vacuum pump (not shown) for the purpose of emptying the same of air previous to being saturated and impregnated. On the completion of the first quarter of a revolution of the cop carrier b, b which takes place automatically as described,its nipple groups g2, Will be positioned opposite the mordant eX- traction chamber 7L and its nipple and cop groups g opposite the saturation and impregnation chamber h2.' The nipple groups g2 are then supplied with mordanted cops g5 and the superfluous mordant extracted therefrom as described, while the cops g5 of the nipple group g are subjected to the action of the liquor pump e, which draws the liquor from the tank a, through the same into the saturation and impregnation chamber h2, and through port 7s', cavity k, pipes Z and Z back into the tank 0,. After a sufficient period the cop carrier b, b is rotated for a second quarter of a revolution during which the cops g5 of the nipple groups g2 are subjected to the action of the Vacuum pump (not shown) in the manner as hereinbefore described. On the completion of the second quarter of a revolution of the cop carrier b, b the nipple groups g4 and nipple and cop groups g2 and g are respectively positioned opposite the mordant extraction chamber h, saturation and impregnation chambers h2 and h3. The nipple groups g3 are then supplied with mordanted cops g5 and the superfluous mordant extracted therefrom, while the cops g5 of the nipple groups g2 and g are subjected to the action of the liquor pump c, as previously described, thecops g5 of the nipple groups g' thus receiving a second saturation and impregnation. After a second period the rotation of the cop carrier b, b is continued for a third quarter of a revolution, during which the cops g5 of the nipple groups g4 are subjected to the action of the vacuum pump (not shown) in the manner described. On the completion of the third quarter of a revolution of the cop carrier l), b the nipple groups g3 and nipple and cop groups g4, g2 and g are .respectively positioned opposite the mordant extraction chamber h', saturation and impregnation chambers h2 and h3, and dye liquor extraction chamber h4. The nipple groups g3 are then supplied with mordanted cops g5 and the superfluous mordant extracted therefrom, while the cops g5 of the nipple groups g4 and q2 are subjected to the action of the liquor pump e, as previously described, the cops g5 of' the IOO nipple groups g2 thus receiving a second saturation and impregnation. The cops g5 of the 'nipplegroups g in the meantime are subjected to the action of a suction pump (not shown), which is in communication with the chamber h4 by means of thepipe m and port m', for the purpose of .extracting therefrom the superfluous dye,'which completes the dyeing of the cop groups g. After a third period, the rotation of the cop carrier 19,5 is continued for the remaining quarter of a revolution, f during which the cops g5 of the nipple group g'3 are subjected to the action of the vacuum pump (not shown) in the manner described. On the completion of the fourth quarter of a revolution of the cop carrier b, b', the nipple and cop groups g have arrived at their starting poi-nt, viz., the mordant extraction chamber h', where the dyed cops g5, are substituted for mordanted ones, While the nipple and cop groups g3, g4 and g2 are respectively positioned opposite the saturation and impregnation chambers h2 and h3 and dye extraction chamber h4, and the cops g thereof are subjected to the action of pumps as hereinbefore described.
