I 4 Claims.
My invention relates to washing machines, and particularly to that class in which a fan operated vacuum cleaning machine is used to agitate the washing liquid. Whereas in. the past, vacuum cleaning machines were used to operate reciprocating mechanisms which in turn agitated the washing liquid, it is my aim to directly circulate the air through the washing liquid, in a manner fully described below, thus providing an efcient method of ,washing clothes, dishes, etc.. without using any other moving parts than those already incorporated in the vacuum cleaning machine.
, It is an object of my invention toprovide an inexpensive washing device, thereby increasing the utility of the vacuum cleaning machine. It is a further object of my invention to provide a portable washing machine that can be placed upon a stove and the .water heated, that can readily be filled and drained,"that can be adjusted to vary the degree of agitation, and that can dry the clothes, all as substantially herelnaftershown and described. Other and further objects will hereafter appear. 4
In the accompanying drawings, Figure 1 is a transverse vertical section of my washing device showing the vacuum cleaning machine in position. Figure 2 is a plan view of the same without the vacuum cleaning machinein position to i more clearly disclose the construction.v Figures 3 and 5 are transverse vertical sections cfa. modiiication of the same. Figure 4 shows the application of the washing device where-the receptacle is replaced by an ordinary-tub. Figure 5 is a section' showing an application of my washing device.
The invention comprises a cylindrical receptacleor container I-,made of. suitable material to hold a quantity'of uid in which the articles to be cleansed are immersed.- and cover 2,
for closing this receptacle so as to make it prac-f tically air tight; this being accomplished byA means of clamping arrangements 4, l, 6, and 1; hereafter designated as the cover clamping device, compressing gasket 3 at convenient points along the periphery of the cover. In the cover.
clamping device, the semi-eliptical steel spring 5 is pivoted in stud 4 which -is secured to the cover by screw 1' through gasket 2 (cover is held tight against receptacle rim by additional force exerted when air is sucked from underside of'cover); the spring l is elongated bycam I, using rim 4I as a fulcrum, thereby compressing gasket l, between the' cover 2 and receptacle I. This means of tightly fastening the cover 2 to receptacle I is used to make possible the use oran (Cl. (S8-37) inexpensive cover and container. It is obvious that the clamping device will vary with the type of cover and container used, such changesin design cannot materially effect the workings of my Washing device. Attached to cover 2, is-suction head 9, which passes through hole 8 and is secured to cover 2, by means of locknut Il compressing gasket 32 thereby making the joint tight. Locknut l I is arranged with slots I2 thus providing a continuous passageway between the interior of the receptacle I, and opening 44 in suction head 9. Baiile plate I9 is secured to locknut I I, by means of a screw.
Centrally located at the bottom of the receptacle I is an inverted U,shaped ring, hereinafter referred to as the agitating ring 30 which isspaced from the bottom of the receptacle by means of legs or spacers 33 fastened or soldered to agitating ring 30. Threaded tube 29 is tightly secured to agitating ring 30 by means of set screw 3 and passes through receptacle (this set screw l arrangement makes it possible to facilitate cleaning recents cle and ring) through hole 21 and is i secured to the receptacle by means of locknuts 28 compressing gaskets 32'. `Threaded tube 29 is.
arranged to receive hose coupling 23 to which ilexiblehose or tube 25 is tightly connected. At the other end of hose 25 is fastened another hose coupling 23, both being interchangeable, to which is connected the air flow regulation or relief valve I8, which can be regulated by sliding of solid disc I9 about thumb screw 20 disclosing more or less of opening 49 in the air iiow regulator I8. The air now regulator is arranged with setscrews 22 and thumb screw 2l to it any diameter of vacuum cleaning machine discharge, the joint being made tight by means of gasket 24. The
suction end or nozzle 41 of the vacuum cleaning `machine is tightly secured to suction head 9 by means of thumb screwv I5 screwingy down on suction end 41 through clamp I6 which is pivoted to suction head 9 through bolts I1. Clamp I6 swings about I1 ymaking it easy to remove suction uum cleaning machine I4, after being operated, Without the dust bag, a short time to clear the machine of any latent dust is ready to be used in the washing cycle. 'Ihe suction nozzle 41 is placed on suction head 9 so that it completely cover." opening 44, then is clamped into position by means of thumb screws I5. Likewise, air ow 1 egulator I8 is tightly fastened into position by tightening thumb screw 2I, set screws the receptacle, approximately 1 inches.
22 being preset for the size of discharge opening. The washing machine is now readyfor use. The cover 2 is removed with the vacuum cleaning machine attached, the material to be cleansed is inserted in the receptacle and water added, either 4by pouring the'water over the open top of the receptacle I or else by means of flexible tube 25 to the height of the water line I0 in However, if too much water has been added the surplus can readily be drained by means of flexible tube 25, which when not in use is hooked on handle 34 by means of hose hook 26 to prevent draining of contents. The use of same tube for air ow and drainis fool-proof against draining while machine is in washing operation.
With receptacle I now filled with water and washing uid to the proper level cover 2 together with the attached 'vacuumv cleaning machine I4 is clamped into position through its clamping device and .flexible tube 25 is coupled to the air flow regulator I8 through coupling 23. The vacuum cleaning machine I4 is then started effecting the recirculation of air and steam in the following manner. Air andsteam is drawn from the upper portion of the receptacle I into the vacuum cleaning machine through suction head 9, and discharged through` opening 49 forcing the air and steam through air iiow regulator I8 down tube 25 and into the agitating ring 30, air then being forced out at varying points along its inside edge' 5I and outside edge 52, returning air and steam to the upper portion of receptacle I thru the washing fluid and contents. of the agitating ring 30 throws the material and washing uid toward the center of` receptacle I while the air leaving the inside edge 5I throws the material and washing fluid toward the receptacle wall, thereby lgiving a to and fro motion to the contents, in addition to the action of the air in its vertical travel, forcing soap -suds thru the material; this latter action thoroughly looses the dirt from pores of the material while the former Washes the dirt from the material and keeps it in suspension to be removed when the washing -liquid is thoroughly discarded. It is desirable to vary the force of this agitation, making it weaker for ne fabrics and stronger for heavier and coarses fabrics, and for vthis purpose the air flow regulator I8 was devised. The .operation of the air flow regulator is simple; thumb screw is unloosened allowing a lateral motion to valve disc I9, as this valve disc is slided to expose more of opening 49, less air reaches the agitating ring 30, passing less air through'the receptacle; likewise as less of the opening 49 is exposed, more air reaches the agivtating ring passing more air through the contents and the receptacle causing more agitation as described. Furthermore, when vacuum cleaning machines are too powerful, a vpressure is built up in theffan casing-which cannot beentirely relieved by the agitating ring 1n which case air and steam tend to leak out from other The air leaving the outside edge 52 sources, such as fan bearings, etc.; to avoid this the air ow regulator I8, can be used as a relief valve by adjusting valve disc I9, until any such leaks if present are eliminated. Baiile plate Il is used to avoid an excess of washing liquid from being carried over into the vacuum. cleaning machine. Y Y
I find that approximately 15 minutes, more or less, is required for a complete washing operation, depending upon the nature of the materials being washed, the cleansing agent used and whether hot or boiling water is used. The washing operation completed, the ilexible tube is disconnected from the vacuum cleaning machine, at the regulator end, and the water drained through 25, and rinse water added. The
rinsing operation is accomplished in the same manner as the washingv operation. The rinsing can be repeated as often as desired for best re' V sults, the vacuum cleaning machine being op-v lexcept that suction head 9 is arranged to be unscrewed from coupling 35 which is secured to cover 2 by means of locknut II and gasket 3'2. By this means air flow regulator I8 can be interchanged with suction head 9. With air flow regulator in newposition shown it becomes possible to damp dry the clothing as follows: Prior to the washing operation previously fully described, the coarsely woven wire disc 9B is secured to agitating ring 30 by means of screws 53. The introduction of this coarsely woven disc does not effect the washing operation as described. Likewise the material is trououghly washed, rinsed and water drained as fully scribed. The suction head 9 is then removed and replaced by air flow regulator I8 and the vacuum cleaning machine fastened to I8 by tightening thumb screw 2|, leaving suction nozzle 41 exposed to the atmosphere.' The valve disc I9 is kept in a closed position. Thervacuum cleaning machine is started, forcing dry air into the upper part of the receptacle I. 'Ihis air pressure compressed the clothes against wire disc 98 thereby forcing the water down and out through drain hose 25. Continued operation of the vacuum cleaning machine causes fresh dry air to pass through the material carrying the moisture along with it. The ldegree of drying depends entirely upon the temperature and quantity of air passed through the material.
As stated, Figure 4 'shows the application of theby an ordinary' tub. 'I'he arrangement of parts and principle of operation remain the same, ex-
cept rigid tube 39 replaces flexible tube 2l since draining is no longer a problem. with arrangements on tube 39 so that it rigidly keeps the agitating ring in position. Likewise, that the agitating ring must be increased in size and I find that for best results, the agitating ring shouldA be about one fifteenth the working volume: by working yvolume being meant the space occupied by the vwashing liquid and contents, the working volume never exceeding two thirds the total volux'ne of the container.
-cial type vacuum cleaner, I may utilize my gen-- 1 eralv structure of the cleaner or working portion with a motor blower or air circulating device especially built for the particular-receptacle and adapted to be mounted and connected to the cover thereof in lieu and in place of the blower portion of any commercial vacuum cleaner device.
What I claim and d sire to secure by United States Letters Patent is.:
1. A washing appliance adapted for combination with the blower portion of a vacuum cleaning device, comprising a washing receptacle, a cover for said receptacle, a suction chamber in said cover in communication with the receptacle, means for supporting said vacuum cleaning device by said cover and for connecting the suction nozzle of said vacuum cleaning device to saidy suction chamber, tubular means for connecting the discharge outlet of said vacuum cleaning device to an inlet in the lower portion of said receptacle. l
