REVOLVER COTTON-MERCEBIZING MACHINE.

Specification of Letters Patent.

Patented Sept. 10, 1912.

Application filed June a, 1909. serial No. 499,948.

To all whom it may concern:

Be-it known that 1, JOHANNES KLnInnwnrERs, manufacturer, :1 subject of the Klng of Prussia, residing at Krefeld, 1n the German Empire, have invented a new and useful Revolver Cotton-Mercerizing Machine, of which the following is a specification:

. My invention relates to improvements 1n revolver cotton mercerizing machines, according to which the revolver system for cotton mercerizing machines is arranged in horizontal position, around a vertical main axle.

A machine conforming to the present invention differs from all the known machines in the rollers being supported horizontally.

and all the driven ones converging to the center of the machine. The other rollers remaining parallel to the driven ones are mounted on crank shafts, and thereby all the rollers can be supported twice in a single common casing. By doing so the machine becomes as stable as necessary and the rollers are so secured that they are able to stand the tension necessary to the mercerization process without nipping or deflecting. The whole arrangement of the mechanism is also more simple, and the parts are more easily accessible.

With this new machine each single operation, the treatment with lye, the squeezing and washing, the taking up and 01f of the hanks takes place in the same horizontal plane, whereby the intermixture of the liquors is avoided. This arrangement has the further advantage of providing a treatment rated and used only for one purpose and not at one time for the treatment with lye and at another time with acid. The horizontal position of the hanks is of great efficiency in all operations as a large surface of the hanks is presented always to the lye without the rollers dipping too much in the lye, and without the lye being soiled by the lubricant of the rollers. In the vertical machines having rollers one above the other the lower roller has to be positioned entirely in the lye in order to dip the same amount of yarn, whereby the oil of the rollerbearings may spoil the lye. 1 A great advantage is also obtained at the washing period by the great surface the hanks present to the flowing water and thus this operation is very efficient. Another thing may also be mentioned here as it constitutes a main part of this invention. A special driving mecha nism for the revolver is not necessary according to the new arrangement, as the mechanism driving the rollers also turns the revolver at the end of each single operation automatically.

The object of the invention will more fully appear in the following specification taken in connection with the accompanying drawings, in which- Figure 1 is a vertical section on the line (u-a of Fig. 1, Fig. 2 is a vertical view in elevation, Fig. 3 is a plan view of cam disk 35, Fig. 4 is a plan view of the machine, Fig. 5 is a detail View of the squeezing apparatus, Fig. 6 is a detail view showing the roller adjusting mechanism, Fig. 7 is a front view of the mechanism shown in Fig. 6.

The machine is shown as having 6 pairs of rollers shown in Fig. 4 as 1-6. In this arrangement the treatment of the several hanks of yarn is carried out by a full revolution of the revolver. When the pair of rollers are at position 1 the treated material is taken off and the fresh charging occurs,

which is treated in the positions 2 and 3 with lye, and in position 4 the lye is removed from the cotton by squeezing it with rollers. Then in position 5 the yarn is'cleaned by means of washing in warm water and a neutralization follows in a bath mixed with sulfuric acid. In position 6 at first it is washed with cold water and then dried by squeezing rollers to such a degree, that after advancing to position 1 the material has become nearly dry and may be taken off.

To carry out the process of mercerization the cotton is placed upon a pair of horizontal rollers 7, 8, of which 7 is driven from the main shaft 9 and pulley 10 by means of the bevel gear wheels 11 and 12, the gears 13, 14, 15, 16 and the bevel gear wheel 17, which acts upon the six conical wheels 18, mounted on the shafts 19 of the rollers 7, see Fig. 1. The shafts 19 carrying the rollers 7 are supported in two bearings 21, 22 of the casing 20 inclosing also the shaft 23, which servesto turn the revolver after each operation of the rollers and therewith to change the-position of the same. The rollers 8 are driven by the rollers 7 throughthe tension of the cotton hanks only and, as the hanks vary in length, the distance between the rollers 7 and 8 has to be regulable. For this purpose the rollers 8 are pivotally mounted on crank shafts 24, the bearings 25 and 26 of which are fixed in the casing 20. Consequently if the revolver revolves, the rollers 7 and 8 move with it and remain at the same distance from one another.

To the journal 27 of each crank shaft 24 the hub of a lever 28 is fast to which in turn a lever 29 is pivotally mounted at 30, the lever 28 having an extension 31 projecting into the recess 32 of the forked lever 29 and guided by it, and connected by a set screw 33 loosely connected in the arm 28 and lever 29 to alter-the distance between both and thereby the distance between the roller 7 and 8 at the charging period. To thelever moving the roller 8 toward the roller 7 and then in the opposite direction. In the position 1 shown in the Fig; 4 the rollers 7 and 8 have their shortest distance because the roll 34 belonging to the respective lever 29 is in yum out-most'curve ofthe guiding disk 35;

taking off and feeding the cotton on to the rollers may be done easily. When the revolver is rotated and the 1 newly charged rollers 7 8 are approaching the position 2, the distance of the rollers becomes increased by lever 30 being forced inwardly by the roll 34 following the path of the curve in the cam disk to such a degree that the hanks have the required tension when the rollers have reached position 2. The cotton hanks having different lengths when fed .on to the rollers are requiring their adjustment and for this purpose the set screw 33 is used.

To bring the roller pairs in the difierent positions 16 and allow the necessary time to perform their respective functions the revolver is rotated intermittently by the following means: FrOm the main shaft 9, the gear 16 is driven by the intermediate gears 11, 12,13, 14 as hereinbefore described, and the conical wheel 17 connected with the gear by screws or other means engages the conical I wheels 18 operating the rollers 7. The shaft 23 and the casing 20 connected with it by a bolt 84 are rotated by thelgear 16 when released to do so because the rollers offer more resistance due to the great tension of the cotton hanks and therewith to the high axial pressure in the'bearings to their respective movement than the whole revolver, especially in view .of the fact that the casing or turn table 20 is provided with wheels 38 running on asuitable path 39 of the frame 40 which facilitates its movement. Therefore the turn table has to be locked when the rollers are in the operating position and this is done by a locking pin 41 in a casing 42 which released to the action of the spring 43 enters one of the six equidistant notches 44 provided in the casing 20 corresponding to the six diiferent positions of the rollers. To draw back the locking pin 41 out of the notches and of the way of the revolver, on the rod 45 of the locking pin 41 one end of a lever 46 is fixed, supported in a bracket 47 of the casing 42. From the main shaft 9 by means of a worm 48 and worm wheel 49 and the shaft 50, a cam disk 51 mounted thereon is driven, the cam 52 of which acts on the hooked end53 of the lever 46 thereby rocking it and removing the lockingpin 41 out of the notch 44, releasing the revolver to revolve until the locking pin enters the next notch or guide hole. After each revolution of the cam disk 51 the revolver makes of a revolution, the conical wheels driving the rollers 'Z are put in rest and the locking pin 41 rides idly upon the edge of the casing until it is caught again at the next guide hole 44 whereby the revolver is locked and the rollers rotating perform their proper function.

As mentioned hereinbefore the impregnation of the cotton hanks with lye is effected at position 2 and 3 of the rollers. As may be seen from Fig. 2' the tanks have to be lowered to allow the rollers to pass by each movement of therevolver. For this purpose the tank 85 is provided with a beveled surface 54, on which small wheels 55 n1ounted in advance of each roller set on the easing or turn table 20 move forward when the revolver revolves, thereby pressing the tank down and giving the roller pair the path free. The tank is held in and returned to its normal position by any suitable means. Arrangements in any well known manner are also made to lead back the used lye to the receiving tank while fresh lye flows in. Care is thus taken to secure suflicientimpregnation especially as allthe under part of the hanks is in the lye and, as already said, a large surface is presented to it. To press out the lye at position 4 a pinching or squeezing roller-63 is provided mounted on angle levers 64 (Fig. 5) the other ends of which are engaged by the rods 65 surrounded by compression springs 66, one end of which bear against brackets 67, the other against collars 68 on the rods. Any lye remainingin the, cotton hanks is removed by washing in warm water at position 6, whereas at position 5 a further washing and the neutralization bytreating with acid occurs. Flowing 78 described heretofore.

in of the washing liquids has to be regu-- lated and this is done by the curved cam disk 51 (Fig. 4), having curved grooves 69 by which the levers 70 and 71 are operated. The lever 70 forms a bell crank lever with the two-armed lever 72, the arms of which are connected with links 73 and 74 with the levers 75 and 7 6', controlling in a well known manner the valves 77' and 78. These valves govern the inflow of the liquids to the pipes 7 9 and 80 of which pipe 7 9 leads warm water and the pipe 80 acid for neutralization. The cotton hanks having reached position 6 are again washed, but with cold water the inlet valve 81 being controlled in the same manner through the cam disk 51 by the lever 71 as the valves 77 and From the pipe 83 the cotton hanks become watered and thoroughly washed and then dried by, a squeezing device like at position 4 (see' Fig. 5).

It is obvious, that another pair of rollers may be interposed between the fourth and fifth roller pair, where the cotton hanks may be pinched or squeezed again and at the same time damped or steamed by water. In this manner the lye is extracted in the highest possible degree. this purpose may be arranged as at 5 or 6.
