- T all whom it may concem:

Be it known that I, ALFRED HAGBART WEIHE, civil engineer, citizen. of Norway, residing at Villa Skjonhaug, Baekkelaget, near (Jhristiania, Norway, have invented certain new and useful Improvements in a Combined Washing, Rinsing, and Wringing Machine, of which the following is a specification.

My invention relates to a combined washing-, rinsingand wringing-machine and is mainly characterized in this, that the washing agent is pressed through the clothes, etc, to be washed, without any stirring or rotation of these articles taking place. Suitably this is obtained by means of the centrifugal force, the clothes being placed in a fast revolving drum, at which the supply of the washing agent is arranged adjacent to the axis of rotation, whereas the outlet of the said washing agent is arranged at the periphery of the drum. By arranging a pumping device in connection with, the revolving drum it is possible to circulate the washing agent so that it perpetually is conducted back to the central axis of the drum. The employment of the centrifugal force for the washing also involves the advantage, that the machine may bedirectly used for the rinsing of the clothes and for the removal of humidity or moistness from the same. When rinsing it is only necessary to supply pure water to the drum instead of the washing agent, and when removing the dampness it is only necessary to turn off the supply of water or washing agent and to draw Off such quantities of water or washing agent as might beat hand in the apparatus.

From the above mentioned facts it is evident that the washing-machine here described is essentially advantageous in comparison with similar machines previously known. Firstly the clothes are spared to a far higher degree than in such washingmachines in which the clothes are stirred or rotated in the washing agent. Secondly the machine possesses the advantage that the clothes may be washed, rinsed and dried in a continuous row of operations without it even being necessary to remove the same from the drum. The invention therefore involves a more gentle treatment of the clothes and a cheaper washing of the same, than hitherto was possible.

The invention is shown in the accompanying drawings, in which:

Figure 1 is a vertical section through one construction of my machine.

Figure 2 is a vertical section through another construction.

In Figure 1 -1 denotes the outer machine container with the bottom 2- and the conical hood -3. -4- is the escape for the steam or vapour. The container is by means of-the bottom --5 divided into two compartments one above the other. The centre of the bottom 5 comprises a bear ing for a vertical shaft 6 in connection with packing and stuffing box -7-, intended to prevent the leaking of the Wash- 1n agent.

he shaft is further supported by a bearing 8 in connection with a bearing block 9, which is screwed or otherwise secured to the bottom 5. At the bottom -2 the shaft -6 is carried by a foot bearing 10, which preferably is constructed as an anti-friction bearing. The shaft 6 carries a belt pulley 11 and is driven by means of a belt -12, which is conducted through an opening 13- in the lower compartment of the container 1. The two compartment-s are made up of two separate bodies as shown in the drawing. In connection with the bottom 5 is arranged an outlet or discharge pipe -14 with .tapping cock 15-. To secure a tight connection a stufling-box 16 or the like is provided. 17- denotes radial vertical walls or partitions at the bottom of the upper compartment of the container,

which walls will prevent the washing agent in this part of the container from partaking in the rotation. Upon the shaft 6- a vane-wheel is arranged, which is open below and comprises a conical outer wall 18-, a nave -19- and substantially axial vanes 20-. Upon the vane-wheel a perforated cone 21 is placed, whose upper edge is connected to the shaft --6-- by a cover or lid --22, which is screwed upon the shaft. The cone 18 has an outer flange -23which is outwardly inclined and serves as a support for a tight bottom --2l-, to which at the periphery a perforated cylindrical wall -25- is connected, whose upper rim 26 is inwardly bent in order to reinforce the device and to prevent escape or waste of the washing agent.

The machine operates in the following manner:

The clothes or the like to be washed are placed in the cylinder 25 whereas the washing agent (lye-water, benzine or the like) is filled into the upper compartmentof the container 1--, so that it covers the lower edges of the vanes -20, but does not extend into the cylinder 25-. The machine is thereupon started. As soon as the velocity of rotation'has reached a certain limit, the washing agent will commence to rise alongside of the inner side of the cone 18 and will reachinto the cone 21. Through the holes in this the washing agent now by means of the centrifugal force will be forced through the clothes. The centrifugal force will further effect that the clothes are pressed against the inner wall of the cylinder 25. Through the holes in this the washing agent will now ass out into the outer container whereupon it will flow down. the inner wall of this and between the partitions -17- be carried back to the vane-wheel to be conveyed through the clothes anew. When the washing has lasted for a sufficient time, the rinsing may take place. To effect this the washing agent is discharged through the cook 15 and pure water is supplied. After the rinsing the water may easily be pressed out of the clothes by letting the machine work without supplying water to the same, simultaneously drawing off such water as might be present in the apparatus through the cock 15-'. Through the action of the centrifugal force the clothes are thus to a great degree relieved from moisture.

The construction shown in Figure 2 acts in the same manner as the one shown in Figure 1, but differs from the latter in this, that it is driven from above by means of the toothed gearings -27-, 28 and that the washing agent is carried back to ing agent from coming into contact with the shaft proper. In s construction the washing machine is combined with an arrangement for direct heating of the washing agent, the lower part of the machine being built up as a fire-place, from which the combustion products will pass underneath the bottom -5-.

It will be understood that the invention is not in any way restricted to the heating system here shown. The heating may be effected by means of steam, gas, electricity or oil and may be'carried out at 'a convenient place outside of the machine;

Having now described my invention, what I claim as new and desire to secure by Letters Patent is In a washing machine the combination with a container adapted to receive the washing agent, of a rotatable shaft passing through the center of said container, means for rotating said shaft, an inverted hollow cone secured to said shaft near the bottom of said container and formed with vanes inside, a perforated drum supported by the said cone, and an inverted hollow perforated second cone carried by the said first cone forming an extension thereof, the said first cone conveying the washing agent from the base of the said container to the second cone to be expelled therefrom by centrifugal force with uniform pressure into the said drum.

In testimony whereof I aflix my signature.
