, k 13 Claims This invention relates to washing machines of the type in which the clothes container is a drum, or in the general form of a: drum,'or hydrowheel, movable about an axis in the casing in 5 which a cleaning fluid is placed to a given level,
and has for its object a means, or an arrangement of the drum and the casing, which means, during movement of the drum about its axis, causes the fluid to be carried around the drum, and in addition forced radially inward through the perforated wall of the drum into-the interior thereof from the space between the drum and "f the casing. Y
The cleaning fluid used in a washing operation isfilled into the casing to a level' considerably below the axis of the container, thereby providing a relatively low level of cleaning fluid within the casin'g.- It will be seen, therefore, that'less cleaning fluid is required in the present machine as compared to washing machines now on the market using a relativelyhigh level of cleaning fluid which extends substantially to the axis of the container and consequently requiring the use of considerably more cleaning fluid in order to fill thewashing machine to substantially the axis of rotation ofthe container. In the present washing machinethe use ofless cleaning fluid results in considerable savings of water, detergents and other cleaning fluids, but due to the characteristics of the machine the clothes or other material therein are thoroughly cleansed,
- in a minimum amount of time.
reticulated, and means for causing the fl uid to be forced inward into the drum while being car: ried through the space around the drum during the movement of the drum about its axis.
The washing fluid maybe water, with or with- 5 out soap, or chemicals, or a dry cleaning solvent. The casing is preferably in the general form of a complete cylinder and preferably arranged with its axis extending horizontally.
l designates the stationary, cylindrical, hori- 10 zontal casing mounted on a; suitable base 2.
3 is the clothes container, drum, cage, or hyi dro-wheel, mounted in the casing to move about a horizontal axis A. During the washing opera- 1 'Ilhe invention consists in the novel features and in e combinations and constructions here- 35- inafter set forth and claimed.
.In describing this invention, reference is had to the accompanying drawings inwhiclr like 40 Figure 1 is a. perspective view, partly in section,
of a washing machine embodying this invention.
Figure 2 is an enlarged,- transverse, sectional vlew'through the clothes container drum, or hy- *dro-wheel, the casing and contiguous parts ofthe base ofthe machine being 1.50 shown.
I Flgures3and4areviewssimilartol igure-2 of other embodiments of the invention shown in Figure 2.
Insofar as this invention is concerned, the m- 50 chine comprises a casing for receivinga washing fluid, solvent etc., to a given level by partly submerging the clothes in the container, or drum,
with a space around the drum between it and the casing, the drum being rotatable about an ,tion, the drum isoscillated aboutits axis, or 15 moved several times in one direction about its axis, and then several times in the other direction, this turning first in one and then in the other direction being repeated throughout the washing period, or operation. The drum 3, or 20 at least the circumferential wall thereof, is fo-' raminous, or formed with slots or perforations, and the term perforated is used in its general sense, and intended to comprehend any open work, or mesh, constructiom wherein thewall 25 of thedrum permitsthefluid topassasfreelyas possible. therethrough. As here shown, the drum is formed of sheet metal having perforations 5 therethrough located close together. The perforated cylindrical wall of the drum is also 30 formed with inwardly extending hollow perforated ribs, or buckets 3 which facilitate the lifting and tumbling of the clothes during the movement oithe drum about its axis. The ribs 7 extend lengthwise of the drum from end to end 88 'and the space between the hollow walls thereof open through the periphery of the cylindrical wall forming an inlet for a copious supply of fluid lifted or circulated up through the passages on opposite sides of the drum. 4 The ribs or buckets 4o also'provide means whereby the cleaning fluid is forced therethrough directLv-upon the clothes or other material in the drum. The drum is also formed with peripheral blades or paddles I which act to carry, or pump, the fluid upward from the bottom portion of the casing around the drum, as the drum moves in one direction or the other. about its axis.
' The forcing of fluid radially inward into the drum through the foraminous perforated, or reticulated, wall of the drum as the fluid is carried, or pumped, upward around the drum by w the movement of the drum about its axis, includes meansasawallofthecasinglocatednearerthe 5: axis and being ioraminous, tar-perforated, or} of the drum than the. remainder of the casing, so that it restricts the passage of the fluid through the space around the container on one side, as the upper side of the drum, so that due to the restriction, the fluid is forced, or squeezed, radially inward to the drum against the centrifugal force imparted to the fluid. The pressure of the fluid is greatly increased by the pumping action of the drum, due to the paddles 7.
In the construction shown in Figure 2, the restricted passages 8 are provided on opposite sides of the drum by the upper portion 9 of th cylindrical wall of the casing being located nearer the axis A of the drum than the remainder, of said wall of the casing, and this is accomplished by mounting the drum with its axis A eccentric to and above the axis B of the cylindrical casing.
In Figure 3, the drum is mounted concentric with the axis of the casing, but the restriction of the passages 8 is efiected by providing an arcuate wall, partition or plate Ill around the upper side of the drum, the center of the arc of this partition or plate being below tlfe common axis of the casing and the drum.
In Figure 4, a bafiie, or partition H is shown in the casing above the drum to restrict the passages 8, this bailie, or partition being shown as a fiat plate located in the chord of an arc of the curve of the casing.
Also, as shown in Figure 4, the means for forcing the fluid radially inward into the drum may-comprise, or include, a series of deflectors l2, l3, l4, 15, secured to the wall of the casing on opposite sides of a vertical plane containing the axis, or axes, of the drum and casing, the inner edge of each deflector terminating nearer the periphery'of the drum than the preceding deflector of the series from the lowermost deflector l2 of each series toward the uppermost deflector Hi.
The casing is here shown as formed with an axial loading and unloading door l6 which is alined with an axial door, or door opening in one head of the drum. The drum is supported in the casing and actuated in any suitable manner. Neither the door, nor the supporting and actuating mechanism of the drum, form part of this invention.
In any form of the invention; during the rotation of the clothes container, the fluid is carried from the lower portion of the casing l upwardly above the normal level of the fluid into one or the other of the contracting passages where it is forced or squeezed radially through the perforated periphery of the container into the container and onto the clothes, this forcing-in operation taking place for the most part in the upper portion of the container, adjacent to where it runs closest to the top wall of the casing.
In operation, the fluid is filled into the lower portion of the casing to a level L, a considerable distance below the axis of the container. 'During movement of the drum about its axis, the fluid is carried from the lower, or sump portion of the casing up one or the other of the passages 8, and during its movement through either of these passages is forced inward through the perforations of the casing, due to the restriction of these passages at the upper portion of the'casing. lightzis invention, the washing operation is gre 1y facilitated due to the forcing action of the d radially inward directly upon the clothes or other material in the drum.
