To all 'who/m t may concern:

Be it known that I, ROMUALD J. KARA- sINsKI, a citizen of the United States, residing at Philadelphia, county of Philadelphia, State of Pennsylvania, have invented a new and useful Washing and Drying Machine, of which the following is a specification.

My present invention comprehends a novel construction and arrangement of a combined washing and drying machine, wherein the washing, rinsing, bluing and drying are accomplished by centrifugal action created by a novel distributor and basket revolving at a desired speed, without rendering it necessary to remove the clothes from the machine. l

It further comprehends a novel construction and arrangement of driving mechanism to effect the revolution of the basket and distributor and also of liquid feeding means.

t further comprehends a novel .construction and arrangement of a wash containing basket, novel means for mounting it, and a novel construction and arrangement of a distributor, disposed within the basket and revolving in unison t therewith.

It further comprehends a novel construction and arrangement of shock absorbing means.

Other novel features of construction and advantages will hereinafter more clearly appear in the detailed description and the appended claims.

For the purpose ofillustrating the invention, l have shown the accompanying drawing ai typical embodiment of it, which, in practice, will give reliable and satisfactory results. It is however to be understood that this embodiment is typical only, and that the various instrumentalities of which my invention consists can be variously arranged and organized, and that the invention is not limited to the precise arrangement and organization of these instrumentalities as herein set forth.

Figure 1 represents, in sectional elevation, a washing and drying machine embodying my invention Figure 2 represents a section on line 2-2 of Figure 1.

Figure 3 represents a perspective view of a ball container and its balls, in detached position.-

Similar numerals of reference indicate corresponding parts.

Referring to the drawings :r

1 designates a washing and drying ma-l supporting standards or legs 2 which at their lower ends are flanged and connected 1n any desired manner to a bottom plate 3 which preferably is in the form of a spider. 'I his bottom plate 3 is provided with apertures 4 preferably disposed beneath the ianges of the standards 2, and these apertures form sockets to receive the Shanks of elastic or resilient cushions 5- which are preferably made of rubber and are. recessed at the bottom, as indicated at 6. These cushions 5 rest on the depressed top portions 7 of slides 8 which are preferably formed from sheet metal, and are provided at their bottoms with an annular flange 9, to the bottom of which is connected in any desired manner a ring 10 of leather, fibre or any other desired material which will prevent injury to the floor on which the washing machine is placed.

The standards 2 at their upper ends are flanged to form-a support for a plate 11, which is secured thereto by means of fastening devices 12. The central portion of the plate 11 is deflected downwardly as indicated at 13, and at its lower portion` it has a bushing 14 secured within it. 15 desl ignates a container to receive the cleansing liquid, and the bottom 15' of this container is supported on the plate 11 and secured thereto b v means of the fastening devices 12. 16 designates an inner housing. which is flanged at its bottom in order to receive fastening devices 17 which pass through the plate 11, and through the bottom 15 of the container 15. The housing 16, intermediate its top and bottom, is provided with an inwardly directed flange 18, to which is connected the flange of a sleeve 19 by means of fastening devices 2O in such a manner as to form a water tight joint. At the upper end portion of the inner housing 16, a bushing 21 is provided to receive the lower vend of a sleeve 22, the upper end of which is provided with an outwardly extendin flange which is secured to the bottom of t e wash containing basket 23 by means of fastening devices 24. The cleansingfluid is indicated at 25. and is raised by means of a pump 26 of any de sired or conventional type, which raises the duit 27, which preferably flares at its discharge end and discharges into the chamber 28 from whence it rises through the passage 29 into the distributor 30. This distributor 30 is preferably formed from sheet metal and has an imperforate top and bot tom. The bottom is centrally cut away and is secured by means of fastening devices 24 to the bottom of the wash containin basket 23 and also to a spider 3l. The spi er 31 is keyed or otherwise connected with the upper end of a shaft 32, so that it will revolve in unison therewith, but can with the basket be lifted oill when desired. The distributor 30 is provided with perforations 33 in its side wall, so that the water will impinge against the clothes or wash 34 disposed within the basket 23, and, after it passes through the wash, it passes through the perforations 35 in the outer Wall of the basket 23, as clearly illustrated in the drawing. The bottom of the wash containing basket 23 is substantially fiat at its periph- -eral portion as at 36, and it then merges into an upwardly deflected central portion 37. rlhe side wall of the basket 23 is preferably deflected inwardly at its upper portion as at 38. The container 15 is provided with a removable cover 39. The shaft 32, which eects the revolution of the distributor 30 and the wash containing basket 23, is supported at its lower end by a step bearing carried bythe bottom plate 3, and it preferably rests on a single ball 41. If desired, the lower end of the shaft 32 may be recessed to receive a portion of the ball 41.

The driving mechanism.

42 designates a motor of any desired or conventional type, and preferably an electric motor which is carried by the bottom plate 3. The shaft of the motor' 42 has connected with it a friction wheel 43.

A friction disc 44 is keyed to the shaft 32 so that it is capable of relative longitudinal movement with respect to such shaft. 45 designates a spring the lower end of which abuts against a sleeve 46, the downward movement of which is prevented by means of a pin 47. The upper end of the spring 45 bears against a centrifugally controlled friction member 48, in the form of a disc having the radial channels 49 which receive the balls 50 which are in frictional engagement with the bottom face of the friction disc 44. .The outer peripheral portion of the member 48 is upwardly deiected as at 51, and its downward movement is limited by a stop ring 52 secured to the friction disc 44. The friction wheel 43 is also in frictional engagement with a friction disc 53 which is fixed to a pump shaft 54. 55 designates a spring, one end of which bears against the friction disc 53, and its upper ends bear against a sleeve 56, the upward movement of which is limited by a bearing bushing 57. The friction disc 53 is grooved to receive the forked end of the lever 58 fulcrumed at 59. This lever 59 has connected to it an operating rod or bar 60 which is provided' with a grasping portion and with a headed lug 6l, which latter is adapted to engage with a strap 62, carried by the casing or container' 15. The `container 15 is provided with a discharge port 63 which is controlled by a valve 64, to which is connected an operating rod 65 which is slidable between the inner wall of the container 15 and the guides 66 within the container.

The operation of my novel combined washing and drying machine will now be apparent to those skilled in this art and as follows:

I will first describe the washing operation. The wash is placed within tie wash containing basket 23, and is substantially uniformly distributed within the basket in proximity to the side walls as shown in Fi ure 1. Assuming now that the clothes to e washed are in the basket, the motor 42 is started, whereupon the friction discs 44 and 53 will be driven, as is apparent. The springv 45 has only 7suthcient pressureto retain the friction disc 44 in frictional engagement with the driving friction wheel 43, so that a certain amount of slippage can take place when the machine starts. The friction disc 44 is keyed to the shaft 32, and, as the speed of the shaft increases, the balls 50 due to centrifugal action will travel outwardly thereby increasing the pressure of i the spring 45 and the frictional engagement of the disc 44 with the wheel 43. As (the shaft 32 is connected to the wash basket 23 by means of the spider 31, and as the distributor 30 is also connected to the spider 31 of the wash basket 23, it will be apparent that the distributor and wash basket will re` volve in unison with the revolution of the shaft 32.

The friction wheel 43 is also in frictional engagement with the disc 53 to effect 'the drive of the shaft 54 and thereby of the pump 26, so that the cleansing liquid will pass through the conduit 27 into the chamber 28 and therefrom through the passage 29 into the chamber of the distributor 30. The cleansing liquid, due tothe revolution of distributor 30 and the centrifugal action created, causes the cleansing liquid to pass through the perforations 33 and implnge against and pass through the clothes 34 within the basket 23, thence through the ports 35 in the basket 23, returning to the source of supply 25 within the container l5.

In devices of this character in which the washing action is effected by centrifugal action of the cleansing liquid a large volume n Aof soap fo is present, and, `in order to p evengt such soapl foam from covering the r orations of t e basket 23, the bottom w 37 of such basket is upwardl deected inorder to provide an enlarged c amber between the level of cleansing liquid in the container 15, andthe bottom of the basket. The bottom wall of the basket is .preferably imperforate.

he soon as the clothes have been properly washed, the operator moves downwardly the rod or bar 30 in order to disengage the friction disc 53 from the driving friction wheel t3, which sto s the pump 26. The friction ving wheel 43 is now only driving the friction disc 44, and the drying or extractr g of the wash now takes place.

"i it wash basket is positioned above the permanent level of the cleansing liquid 25, so that the A water does not interfere with the revolution of the basket. lt is not necema to drain ed the water before the extracting actually takes place, and the same cleansing duid can be used for a number of diderent washes, if desired.

lf the operator desires to rinse the clothes before extracting without removing them from the basket 23, the cleansing liquid 25 is drawn ed, and rinsing water placed in the container 15. Ylhe pump is operated to cause the water to pass through the distributor, and from the distributor through the clothes, due to centrifugal action, and

- the proper rinsi action will be edected.

titl

The :in is nent disconnected, and the clothes extracted as before explained.

llf the clothes are to be blued, they are blu in the bluing water in the same manner as the rinsing operation is e'ected.

lt will be apparent from the foregoing that in m resent invention l utilize the centrifual flirce created by the distributor and beset revolving at a high speed, to wash, rinse, and dry the clothes without remog them from the basket.

Special attention is directed to the novel construction and function of the distributor.

s distributor is rovided with an enlarged annular cham er, which, due to the centrifugal action created, is edective to reduce the amount of horse power which it is necessary to employ to drive the pump, so that a motor of minimum horse power can be employed.

l do not employ the pressure created by the water pump to cause the water to impings against the clothes. 'lhe function of the water pump is to cause the water to be raised, so that, due to the centrifugal action, Siphon action and the pump combined, a continuous supply of water will be maintained within the distributor 30. 'lhe discharge of the cleansing liquid within the distributor 30 is edected solely by centrifugal action due to the distributor revolving at a high speed andthe diameter of the sup Y l chamber within the distributor. The v tributor also serves as a gauge for the placing of the clothes in the basket. rl`he clothes are placed between the side walls of the basket and the distributor so that they will be substantially uniformly arranged within the basket, and abnormal or excessive vibracontact with the shaft 32 due to the provi-- sion of the sleeve 19 and the cup shaped cap member 67 so that it is not necessary to employ a shaft which is non-oxidizable.

'lhe machine is supported so that it will absorb the shocks due to the vibration. "lo

accomplish this result l employ the resilient or elastic cushions 5, which center themselves in the depressed top faces 7 of the slides 8.

Attention is also directed to the novel means employed to automatically increase the spring pressure on the friction disc 44 as the speed of the shaft 32 increases, so that any excessive load will be taken up gradually enough to reduce the load upon .the motor in starting and thus prevents overload of the motor.

rllhe friction losses which have heretofore been present in devices of this character have been materially reduced with a consequent reduction in horse power consumed in driving the motor.

The perforated wash basket 23 is supported at the upper end of the shaft 32, and this shaft at its lower end is journalled in an antifriction step bearing. The basket is guided in the inner housing, and the shaft also has a bearing in the plate connected with the bottom of the container. rlhe shaft, so to speak, is floating.

The shock absorbing members 5 are free to adjust themselves on the slides 8 when the machine is in operation.

rlhe shaft 32 is supported and guided in such a manner that the necessity of employing a packing gland is eliminated.

lt will now be apparent that l have devised a new and useful washing and drying machine apparatus which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while l have, in the present instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that this embodiment is susceptible of modification in various particulars without departing hom litt@ lill@ ree the spirit or scope of theV invention or sacrificing any of its advantages.
