PATENT OFFICE.

The subject of the present invention forms a machine in which the under constant Feeding the fabric to be treated washed, pulled, cut during its passage and it is crushed and the same after he has been from the water with which he is been treated, separated, finished.

On the accompanying drawing is

Fig. Ι a side view respectively. an image of the whole machine,

Fig. 2 is a longitudinal section through the same and

3 shows a cross section through the same at the location of the closure opening.

The housing α α consists of the two parts a ¹ and α ² , which are connected to one another in such a way that the upper part a ¹ can be removed if necessary. In the head and rear wall two bearing bushes bb ^{1 are} prepared, in which the shaft of the conical shredding roller (knife roller) c is mounted, which on its surface with triangular shaped ribs c ¹ and the associated, leaning against them rubbers or knives c ² made of solid leather or some other suitable material. The aforementioned blades are wound around the roller in a helical manner.

The bottom part of the housing is provided at its end adjoining the upper part with a groove a ³ into which the rust-shaped, semicircular ribs a ^h (Figs. 2 and 3) are inserted.

A sieve d rests on this grate, the meshes of which are so fine that any loss of paper stock is avoided, but still allows water to flow through.

The upper semicircular part of the housing a ¹ lies with its flange a ⁶ sitting on the edge on the flange a '\ sitting on the lower part α ² both are held together by means of screw bolts. Here, the edge of the upper half of the housing lies on the grate α ⁵ provided with the sieve d and fixes these two unchangeably.

The rear, wider end of the knife roller c is provided with a row of blades c ³ c ⁴ , one of which alternately one (here c ³ ) is so long that it comes close to the sieve d when it is turned.

The other blades c ⁴ are kept shorter and only protrude to a little over the circumference of the conical roller c .

The upper housing half a ¹ is further away from the roller and the knives sitting on it than the sides, so that a chamber a ^s (FIG. 2) is formed. A second chamber a ^{9 is} formed around the blades c ³ c ^{4 by} a partition a ^{w which} is almost round in the interior and extends to the sieve d.

The wall α ¹⁰ prevents the paper stock from entering the chamber α ⁸ into the chamber α ⁹ , while the lower part occupied by the sieve d remains free, so that the sieve

paper stock sliding along can come into contact with the blades c ³ c ⁴ .

The paper stock mixed with a sufficient quantity of water is introduced through the opening a ¹¹ on the narrow part of the housing, is grasped, torn and comminuted by the roller c with the ribs and knives c ¹ c ^2. Here, however, the further upper part of the housing, the chamber a ^s , should always be well supplied with water. For this purpose, located in the vicinity of the above-mentioned intermediate wall a ¹⁰ in the upper part of the housing a second opening α ¹² through which the substance is amply supplied ^r ater W before the same c in the chamber a ⁹ into contact with the blades ³ c * occurs.

To prevent stones, lime and sand particles, which might still be in the paper stock introduced through opening a ¹¹ , from getting between the sieve and knife, a collecting space a ¹³ for these heavy parts is arranged immediately under the aforementioned opening a ¹¹ lower closure plate is set up removable a ^u (Fig. ι and 2). The bottom a ^u can also be set up in such a way that it opens or opens automatically under the pressure and weight of a larger object. pops up. The material is now gradually pressed by the conical roller c and its ribs c ¹ and knives c ² along the sieve d , torn and shredded between this and the knives and finally conveyed into the chamber a ⁹ , where it is carried by the blades c ^s c ⁴ grasped, pressed again all around against the sieve and then conveyed outward through opening a ¹⁶ (Fig. 1 and. 3).

The blades c ³ c ⁴ are not attached radially, but slightly tangentially on the shaft of the knife roller (Fig. 3); the smallest of these blades is still somewhat larger than the radius of the knife roller (cf. c ⁴ in FIG. 3). The aim of this inclined arrangement of the blades is that the paper stock is always thrown or thrown against the wire in one direction. is pressed in order to remove the water as possible from the finished torn material and to make it easier for the blades to be thrown out through the opening a ^K. The lower part a ^{1 of} the housing is bulged downwards and prepared with an opening α ¹⁶ for the discharge of the water coming out of the sieve d.

Claims (2)

Patent Claims: 1. A machine for washing and preparing BEZW. Shredding of paper stock, characterized by a conical roller (c) provided with ribs (c ¹ ) and knife (c ² ) made of a suitable material (e.g. leather, rubber, sheet steel, etc.) in a closed housing (a ) with corresponding openings for the introduction of paper stock (a ¹¹ ) and water (a ¹ "), the lower part (a?) of which carries a sieve (d) lying on semicircular ribs (a ⁶ ) , on which the paper stock is passed through the knife ( c ¹ ) is processed while the excess water can drain through the sieve. 2. In the machine marked under! At the front end of the housing (a) the arrangement of a collecting chamber (a ¹³ ) for receiving the parts contaminating the substance (stones, sand, etc.), while at the rear end a partition (a ^w ) a chamber (a ⁹ ) is divided, in which the processed material is grasped by paddles (c ³ c ^ J sitting tangentially on the main shaft), freed from the water and conveyed out of the machine as finished material. 1 sheet of drawings.
