Dec. l5, 1931. E. FREUND SQUEEZING MACHINE Fyiled Dec. 12. 1928 Patented Dec. 15, 1931 PATENT OFFICE EDWIN FREUND, OF VIENNA, AUSTRIA SQUEEZING MACHINE Application led December 12, 1988, Serial No. 325,434, and in Austria December 14, 1927.

This invention relates to improvements in machines for dyeing, impregnating, kneading, and mixing or intimately and evenly compounding by the process of alternately turning and squeezing the materials to be l treated.

Ihe machine comprises a vessel, preferably with two sides parallel to each other, a rocking shaft placed at right anglesto them, a

vane worked by the said rocking shaft alternately towards and away from a plate which stands also at right angles to the said sides of the vessel and is called the butt; a narrow, essentially horizontal ledge at the bottom of the butt and on that side of it which faces the vane and a bottom forming a continuation of the ledge but shaped in accordance with the path swept by the bottom edge of the vane, preferably in such a way that the 2o gap between the bottom edge of the vane and the bottom widens as the vane moves nearer to the butt.

The vane, the bottom and the butt are advantageously made of screen-like materials easily pervadable by liquids.

The faces of the sides of the vane and of its bottom edge are, with advantage, bent forward a little in order to move the material to be treated away from the gaps at the sides of the vane and below, so as not to be caught between vane and sides of the vessel, or vane and bottom.

These forward bent portions and the adjoining ones are free from projections, such :5 as forinstance corrugations which would interfere with the scavenging action of the forward bent wings and bottom lip of the vane.-

The action of the machine will be fully understood by referring to the drawings, wherein Figure 1 is avertical section of the machine, and Figure 2 is a top plan view thereof. f

The parts are indicated by the following -1 5 numbers: The vessel with 1; the covers ofthe charging orts with 2, said covers being v shown in ll. and dotted lines in.l Figure 1;

a pan for placing the goods in after treatment with 3, said pani, forming a loose cover for the center of the evessel 1. The two bottoms are indicated bythe numerals 4 and 5; the butts by 6 and'7 the ledges by 8 and 9; the rocking shaft by 10; the vanes by' 11, said vanes havino forward bent wings 12, 13, 14 andl); and bent bottom lips 16 and 17. The rocking shaft has acrank 18 anda countershaft 19 is also provided which has a crank 2O.y Cranks 18 and 2O are joined by aconnecting rod 21. "The bundles of material treated between the vanes and the butts of the machine are indicated by 22 and 23 and the numerals 24 and 25 represent the bearings of the rocking shaft. The vanes 11 are fixed on arms 26 and 27.

turn stroke said bundle topples over the lefthand side edge of the ledge 9 into the position in which bundle 23 isshown. On the next forward stroke the left-hand side vvane 11 strikes first that side of the bundle 23 which was originally on top and pushes the same up the bottom 4 until it touches butt 6 and squeezes it the-n into a new lump of similar shape as before. While the vane is away from the butt the bundle has time to get well soaked with suds with which the vessel is filled up to the proper level. During the return stroke of the vane theisuds and any matter that has been dissolved by it is squeezed out again and portions of the cloth are shoved pasteach other, rubbing off soft matter adhering. When this action has been repeated a certainnumber of times all dissolvable matter has been pa'sid'i'tb the suds.

The eicienc of the machine is considerably inereased y perforating the supporting surfaces of the bottoms 4 and 5, the butts 6 and '7, and the vanes 11, so that soiled liquid v is quickly carried away through said bottoms and a more thorough circulation of the liquid etl'ected through the butts and vanes. To this end, the central portions of the vanes 11 are provided with perforations 28, while the wings 12 and 13 are formed with the perforations 30. Similar perforations 31 and 32 are provided in the bottoms 4 and 5 and the butts (S and 7, respectively.

It will be seen -from Figure l that the lips orfaces 16 and 17'of the bottom portions of the vanos 11 each form an acute angle with a plane extending through the bottom edge of the lip and the axis of the shaft 10, as indicated by the dot and dash line 33. Also, the faces of the wings 12 and 13 form acute angles with a plane extending vertically and transversely through the shaft 10, said plane being indicated by the dot and dash line 35 in Figure 2 and the acute angles being designated by the numerals 36 and 37.

Dyeing processes are carried on in a similar way except that the coloring mattei' is carried into the material to be dyed.

What is claimed is:

1. A squeezing machine comprising a vessel, a rocking shaft, a vane movable to and fro by the said shaft, a butt facing the vane,

a. bottom shaped in accordance with the path swept by the said vane and an essentially horizontal ledge placed between the butt end of the bottom and thebutt.

Q. A squeezing machine comprising a vessel, a rocking shaft, a vane movable to and fro by the said shaft, a butt facing the vane, a bottom shaped in accordance with the path swept by the bottom edge of the vane, an essentially horizontal ledge placed between the butt end of the bottom and the butt, the vane in its foremost positiony including withy the butt and the ledge a wedge-shaped space, the center of gravity of which lies on the vane side of a vertical plane passing through said ledge.

3. A squeezing machine comprising a vessel, a rocking shaft, a vane movable to and fro by thesaid shaft, a butt facing the vane,

' a bottom shaped in accordance with the path swept by the said vane, an essentially horizontal ledge placed between the butt end of the bottom and the butt, the face of the lower part of the vane forming an acute angle with a plane extending through its bottom edge and through the axis of the rocking shaft.

4. A squeezing machine comprising a vessel, a rocking shaft, a vane having Wings and being movable to and fr0 by the said shaft, a butt facing the vane, a bottom shaped in accordance with the path swept by the said vane, an essentially horizontal ledge placed between the butt end of the bottom and the' butt, the faces of the wings `of the vane in- 5. A squeezing machine comprising a vessel, a rocking shaft, a vane movable to and fro by the said shaft and having wings, a butt facing the vane, a. bottom shaped in accordance with the path swept by the said vane, an essentially horizontal ledge placed between the butt end of the bottom and the butt, the face of the bottom part of the vane forming an acute angle with a plane extending through its bottom edge and through the axis of the rocking shaft, and the faces of the wings of the vane including acute angles with a plane extending vertically through the axis of the rocking shaft and situated between the wings of the vane.

6. A squeezing machine comprising a vessel. a rocking shaft, a. vane movable to and fro by the said shaft, a butt facing the vane, a bottom shaped in accordance with the path swept by the said vane, an essentially horizontal ledge placed between the butt end of the bottom and the butt, and means to removably mount said butt in the vessel.

In testimonywhereof I have signed my l name to this specification.
