Specification of Letters Patent.

Patented May 10, 1921.

Application filed June 15, 1920. Serial No. 389,183.

To all whom it may concem: v

Be it known that I, MICHAEL KRYGKI, a

I citizen of the United States, residing at Sacramento, county of Sacramento, State of California, have invented certain new and useful Improvements in Washing-Machines; and I do declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in washing machines of the type which may be either hand or power actuated, and wherein the fabrics are washed without being touched by the hands.

i The principal object of the invention is to provide a machine by means of which the fabrics will be subjected to both a rubbing action, similar tothat of a common corrugated wash board, and to the action of a vacuum, while being agitated at the same time.

By means of this device therefore I obtain a greater efficiency of operation and shortening of time necessary to launder a given quantity of articles, than can be had with the usual machines for the purpose.

Another object is to so arrange and construct the vital parts of the machine that a small bulk or articles will be washed as thoroughly as a large quantity, that is, they may be subjected to equal rubbing and vacuum pressures.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed. These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views:

Figure 1 is a sectional elevation of the machine. Fig. 2 is an enlarged section of a spring-bearing member. Fig. 3 is a sectional view of a vacuum plunger. Fig. 4 is a bottom plan view thereof.

Fig. 5 is a top plan view of a pawl and ratchet mechanism.

Referring now more particularly to the characters of reference on the drawings, the numeral 1 denotes a frame, of any suitable material, dimensions, and form of constructlon, on which is mounted a cylindrical tank 2 provided with a close fitting cover 3. Arms 4 project upwardly from the frame 1 on opposite sides of the tank and support bearings 5 for a crank shaft 6 having a pair of opposed crank-arms 6 thereon.

This. shaft passes through slots 7 in thecover 4, so that the latter may be removed. This shaft may be turned by a hand wheel 8,

or it may be operated from an electric motor or other source of power.

J ournaled on the cranks 6 and depending therefrom are sleeves 9 having rods 10 slidable therein, the rods being adapted to be moved lengthwise in the sleeves and tobe held in any desired position, as for instance by means of pins 11 projecting through the sleeves at one point and through any one of a number of holes 12 in the rods.

Secured to the outer ends of the rods are cone-shaped cups 13 each having a solid bottom piece 14 a certain distance from the rim of the cone. Substantially deep corrugations 15 extend outwardly from the bottom to the plane of the rim and from side to side thereof, the edges of the corru ations being rounded, as is also the rim. aid corrugations have a plurality of orifices 16 therein, while at certain points orifices 17 are cut through the bottom 14, the area of the'cone inclosed by the latter being otherwise airtight.

These cups are adapted to project somewhat into an open-topped tank 18 positioned .within the main tank and shorter than the same, and whose bottom is formed of widely spaced and heavy wire mesh 19, normally ratchet wheel 24 fixed thereon, which is engaged by a pawl 25 mounted on an arm 26 turnable on the shaft 20, and actuated by means of a rod 27 attached to the 'arm and extending to a bell-crank 28 fixed to the frame 1. From the other arm of said bellcrank a rod 29 extends upwardly to an eecentric 30 fixed to the crank shaft 6 outside the tank 2.

In operation, the cover 3 is first removed and the fabrics to be laundried placed inside the inner tank 18. The tank 2 is then partially filled with water, the cover replaced and the crank turned. This action alternately raises and lowers the cups 13, so that the latter press down on the fabrics, and also cause the latter to be pressed firmly against the wire bottom of the tank 18, subj ccting the fabrics to a wash-board action.

The corrugations in said cups expose an area to the fabrics considerably greater than could be had without their use, while at the same time their shape also subjects the fabrics to a wash-board action. Thus both the upper and lower strata of fabrics are subjected to a Washing action at the same time, the intermediate layers rubbing against each other and being agitated by the alternate sucking action of theplungers.

At the same time, with the revolution of the shaft 6, the small tank 18 is being constantly revolved by the intermittent action of the pawl and ratchet mechanism, thus further aiding the rubbing and agitating of the fabrics.

The fact that the tank 18' is springmounted, allows it to give somewhat when the downward pressure of the plungers 13 is transmitted to the fabrics.

When a few goods are to be laundried, the plungers are lowered in the sleeves 9, thus bringing them nearer to the bottom of the tank 18, and permitting the same pressure to be exerted on the fabrics as when the tank is full, when the plungers are of course raised on the rods.

From the foregoing description, it will be readily seen that I have produced such a device as substantially fulfils the objects of the invention as set forth herei i I While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to and do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention, what I claim as new and useful and desire to secure by Letters Patent is:

1. A washing machine comprisin a vertically positioned tank, an inner tank therein arranged to rotate, cups projecting into the inner tank and arranged for opposed vertical movement and means whereby the inner tank may have a limited amount of automatic vertical play without interrupting the rotation thereof.

2. A washing machine including an outer vertical tank, an inner tank, a spring cushioned shaft supporting the inner tank and projecting through the bottom of the outer tank with a water-tight fit, and means for rotating said inner tank irrespectivev of any vertical movement of saidshaft.

3. A Washin machine comprising a vertically positione tank, an inner tank therein arranged to rotate, a crank shaft arranged for,continuous rotation crossing the outer tank and above the same, said shaft having opposed cranks thereon, cups journaled on the cranks and depending into the inner tank, and means actuated from the crank shaft for imparting an intermittent rotary movement to the inner tank.

'In testimony whereof I aflix m si nature. MICHAEL It CKT.
