Patented in the German Empire on November 23, 1886. Longest duration: July 11, 1898.

At the under No. 25599 patented device for degreasing wool, those described below and in the enclosed Drawings shown changes and improvements attached, which to. refer to two different arrangements.

One of these arrangements, which is illustrated by FIGS. 1 to 4, relates to:

a) the use of prefabricated rollers, which squeeze the wool inside the degreasing bath, and

b) the use of rods hanging vertically on trusses, which are mechanically immersed in the liquid at one end of the degreasing water container and moved in the same for the purpose of slowly driving the wool towards the other end of the container ^x and lifted up here to bring them back to the front end.

The other arrangement, which is illustrated by FIG. 5, relates to a nesting of the containers designated in the main patent with EE ¹ and AA ¹ , as well as the use of divers swinging about horizontal axes, which. Dip the wool flakes flowing on the surface of the degreasing water into the latter itself.

These two arrangements are made in the same order in which they are listed above are described below.

From the first arrangement show:

Fig. Ι a longitudinal section of the main patents described container with constructive changes,

FIG. 2 shows a vertical section along line xy in FIG.

3 shows a basic outline of the container,

4 shows a container E with the parts G, BB ¹ and D mentioned in the main patents, as well as several innovations which contribute to completely degreasing the wool.

The modifications shown in FIGS and additions consist of the following:

The wheel G which dips the wool is followed by one or more pairs of pre-rollers, which are immersed in the degreasing bath, in order to remove the earthy and treacherous components. mainly found in the tips of the wool flakes, softening and causing them to fall down. The pressing device can consist of one or more hollow, canned or perforated or grooved metal rollers, which can also be formed from round or prismatic rods, or from perforated metal sheets, and are placed on one or more smooth or canned metal. Roll rollers made of wood, metal or some other hard material and act by their own weight.

Fig. 1 (and Fig. 3 in outline) shows the arrangement of three rollers cc ^l c ^l , of which

the upper c is perforated and rolls on the two lower smooth rollers cc ^1.

■ The pump F, the piston of which is driven by a lever system / and a washer F ¹ equipped with a crank, is located on the side of the tank.

Only the wheel G of the main patent is retained, and in order to move the wool in the containers, transverse and moving rods, which are provided with teeth and are immersed in the bath, are placed after the pref-rollers.

These rods D ¹ D ¹ D ¹ lie in incisions d equidistant from one another on LJ-shaped angle rails a of the container A and are slowly and periodically lifted and pushed away by the mechanism described below, thus bringing the wool to the exit point from the container . The rods Z) ¹ are then lifted onto a transport device carried by the struts E ¹ E ¹ and brought back again by this, whereupon one after the other is lowered again, so that they step back into the bath in front of the Prefswalzen and their Start the tour again.

The mechanism used here is as follows:

On each side of the container and the transport device rods F ₂ F ₂ F ₃ F _{3 are} attached, which perform a double movement by i. once through the cranks F ¹ F! /// the Xtra and the connecting rods J ^1/1/2/2/8 / back ³ such in the horizontal direction and forth, their DAF. The deflection is exactly the same as the distance of the rods D ¹ from one another when they are at rest (in the present case 20 cm), and then also 2. are moved up and down in the vertical direction. This latter. Movement is brought about by a mechanism which consists of eccentric lifting thumbs JJ , which act on horizontally lying rods MM , which in turn set the angle levers KK into action.

The latter are provided with rollers and periodically lift the rods F ₂ and by means of the vertical rods NN _{sitting on the rollers also lift the rods F 2} F ₀ at the same time . These rods F ₂ F ₂ are raised so high that they pass the toothed rods Z) ¹ over the incisions. Lift dd ^x to move it away and then return to its first position ^{under the bars D 1.} If one of the rods has arrived at the last incision at the exit from the bath, then it is through the forks O O, which by sitting on the rods F ₃ F ₃ and moving with them. Angle lever PP and connecting rods QQ are set in motion, lifted above the level of the upper transport device and placed on the associated rods F ₂ F ₂ . The. Rods D ^ D ₁ provided with teeth are then returned as a result of the to-and-fro movement of the upper transport device in the opposite direction as in the case of the lower transport device and then by means of a counterbalanced device. Device RR lowered onto the lower rods F ₃ F ₃ without bumps.

As soon as the upper rods F ₂ F _{2 have brought} the rods D ¹ to the end of the transport device, they place the last rod on a carrier Z, which is suspended from one end of a chain C guided over the roller r; at the other end of the chain there is a counterweight u. '

After the upper rod F _{2 has carried out} its movement forward, it begins its backward movement and runs the rod D ¹ on the. Carrier Z back, whose previous equilibrium is now disturbed by the weight of D ¹ and, as a result, in a guide attached to a strut X sinks down onto the angle rail α of the container E , where the rod D ¹ then falls from the rod F ₃ , which, while F _{2 made} its backward movement, made its forward movement, is recorded. Since the carrier Z sinks somewhat lower than the incision d of the lower rod F ₃ , the latter takes the rod D ¹ 'with it when it moves backwards. The thus lightened carrier Z rises again as a result of the weight u in order to pick up another rod Z) ¹ _{, which has meanwhile been supplied by F 2} , and to descend with it, whereupon the process described above is repeated. The movements of the rods D are thus intermittent, but always in the same direction; Furthermore, the teeth leading to the wool always remain immersed and only occur at the ends of the container respectively. from the bath. The wool fed to the cloths expands and lets all impurities fall down.

Another important improvement is the construction of the structure disclosed in Patents No. 25599 ^and No. , Which lead towels 31166 described the wool under the Prefswalzen. . ;

So far these cloths consisted of discs or sticks made of wood or metal, which fastened on straps made of leather or rubber or under each other "by metal ones Rings or hinges were connected. This feeding device is characterized by a special Metal mesh replaces, which ■ either consists of interlocking spiral windings

is formed and has the shape of a sleeve, or in the same way as that in the Paper making used metal mesh is made from copper wire.

The meshes of the wire mesh are made so tight that only the water seeps through can and the entire wool is brought under the press.

In order to supply the wool continuously and in small quantities at once to the outlet of the last container E , in which the degreasing of the wool is completed by means of cold water, the inventor uses the modifications described below and shown in FIG. 4 of the drawings.

A drain device L provided with a register is attached to the side of a vessel E of the main patent. The toothed or shoveled wheel G of the main patent is used to submerge the wool. The rear wall of the container E ends in its upper part in a valve T which is on a threshold. U runs out, which leads to the Prefswalzen BB ¹ and from there to the cloth D. The valve T serves to interrupt the flow momentarily and to restore it at a certain moment, and this happens because first after the outflow of the water the Prefswalzen while the door L ^{1 is} raised to. is to let the abfliefsen ^T W ater by L, blocked and läfst leak is then the water and wool to the Prefswalzen while the door is established L ^1, off to the at Abflufs L. lock.

As discussed in the descriptions of the above-cited patents, the paddled wheel G serves to facilitate the exit of the wool and bring it onto the towels. The door X ¹ is raised and lowered by a rotating disk K ¹ with the aid of a thumb h and a system of articulated levers W. If the thumb presses h on the lever arm /, JL ^{1 is} lowered and can only go up again when h is no longer in contact with Z. The outflow of water at L is interrupted by the falling of L} , which necessarily results in a rise in the water in the vessel. At the same time, when the thumb h presses against the arm Z and thereby blocks the water outlet at L , another thumb / j ¹ presses the lever arm Z ^{1 of} a system of levers and connecting rods F ¹ F ¹ , which is connected to the valve T in Connection stands and to. At the same time the threshold U closes and the valve T opens, through which the drain at L is closed. As long as the catch h ^{1 is} in contact with the end P , the valve T remains open, and the water set in motion by the wheels flows over the threshold U and brings the wool onto the cloth C ² , which is between the rollers BB ¹ and from here to the cloth D leads. As soon as a sufficient amount of wool has emerged from the container E , the door L ¹ opens due to the weight of the released levers, and the valve T, on which the system F ¹ F ¹ no longer acts, also falls back and closes new the threshold U.

The current carrying the wave with it ceases, and all that remains is the movement of the water resulting from an ordinary dishwasher. The excess water from fliefst by the weir of L.

By combining the opening and closing movements of L and T , flushing of any degree can be achieved without the aid of any mechanical lifting device. In order to lengthen the contact between the lugs hh ^l and the arms II ¹ , each lug can be guided in a coulisse made in the disc K ¹ and regulated so that it is more or less far from the center point of the disc and thereby the Duration of the contact with 11 \ and thus also the simultaneous closing of L ¹ and opening of T is regulated. .

If necessary, the position of the support points of the levers WW and V ¹ V ^{1 can also be} changed; Furthermore, in order ^{to accelerate the lifting of L 1} and the lowering of T after the contact between the lugs hh ¹ and the arms 11 ^{1 has} ceased, counterweights can be attached to the arm / and the valve T.

Listed in the second of the am'Eingange this specification assembly, which is illustrated by FIG. 5, the sink EE ¹ in the other washing water tank .A .A ¹ used.

In such a case, it is sufficient to provide the washbasin EE ^ at its entry point E with a few bores ο ο ¹ in order to keep the water level in it at a constant height, and the first amendment - patent no. Reservoir L listed as a novelty 31166 together with its communication tubes M and N are dispensable. In this case, too, the bottom of the basin EE ¹ can be continuous or perforated. GG ¹ wheels of the type described in the main patent are again used in the present case as the means for moving the wool.

Instead of the solid supports C and C ^{1 shown} in the previous patent specifications, on which the wholly or partly defatted wool is fed to the prefabricated rollers BB ^[ , an endless feed cloth C is drawn in the present case, which is around a at the bottom of the The roller mounted in the basin loops.

The most important part of the innovations illustrated in Fig. 5 is the arrangement of one or more diving handles Z, situated between the wheels GG ¹ , which are intended to immerse the wool flakes remaining on the surface of the degreasing liquid in the bath so that they are completely soaked.

The diving handle consists of a wooden or metal plate, which is included in the Wall of the basin horizontally mounted pegs or with a pin reaching through the latter Axis is connected.

If only one such diver's handle is arranged between the wheels G and G ¹ , it is sufficient to lengthen it to "bring about its oscillating movement beyond its pin and to connect it here to a load weight or to a spring to cause it to be placed horizontally" and to thereby connect it to situ irish so, that he from the excellent edge BEZW. blade ends of the rear wheel G ¹ hit and ¹ · thus is in verticale or at least turned into highly inclined position.

In most cases, however, it would be advisable to attach the pivot plate Z to an axis that extends through the side walls of the basin, which carries a lever on top of it and is forced to oscillate by means of an eccentric mounted on a rotating shaft or by other means.
