24 Claims.

This invention relates to fabric cleansing machines and has for its object the provision of a machine of utmost simplicity, economy, and compactness, capable of performing washing and extracting operations by hand-power and operating with a minimum amount of liquid. This machineis designed with special reference to drycleaning operatioiisbut is likewise useful for performing small washings with soap and water as the cleansing medium.

In the drawings accompanying and forming a part of this application I have illustrated a preferred embodiment of my invention, wherein Fig. 1 is a sectional view showing the device arranged for the washing or cleansing operation; Fig. 2 is a similar view showing the device arranged for the extracting operation; Fig. 3 is a vertical, sectional view corresponding to the line 33 of Fig. 2; Fig. 4 is a perspective view of the device 2 arranged as shown in Fig. 1 but with the cover removed; Fig. 5 is a perspective view showing the machine adjusted as illustrated in Fig. 2 but with the cover removed; Fig. 6 is taken on the line 6-6 of Fig. 3 and is a detail view of one of the brackets showing the arrangement of the operating and suspending mechanism; Fig. 7 is a sectional view of a modified form of crank driving means; and Fig. 8 is a detail sectional view of the crank clutch corresponding to line 8-8 of Fig. 3.

Describing the parts by reference characters, my improved washing machine comprises a liquid-holding casing I, a clothes-container 2, a cover 3, and a supporting frame 4, in conjunction with certain gearing and connecting and agitating devices. The casing I can be described as approximately kettle-shaped, namely substantially hemispherical with its bottom-part merging into a spherical portion; excepting that the bottom-part is introverted somewhat eccentrical- 1y as illustrated at 5, this being in its simplest form, essentially a large dent which is provided for a purpose to be hereafter.described. The frame 4 is made with 'a bottom-part 6 to rest on a table, and is form-ed at each side with an upstanding bracket'l closely embracing the casing and preferably of somewhat spherical contour so as both to produce added strength and to embrace the casing closely as illustrated in Fig. 3. Each of the brackets is provided at its upper end with a pivot element 8 operatively connected to the casing so that the casing .is mounted to swing upon a horizontal axis.

The clothes-container 2 consists of a foraminous basket, also partly of spherical contour, slightly smaller in diameter than the casing.

This basket comprises approximately that portion of a spherical surface extending from near its equator to about two-thirds of the distance to one pole where it is formed with a rolled rim to defining a working opening. At the end opposite 5 to this opening the wall of the container is turned more abruptly inward to form a perforated web I l which is tightly joined to the peripheral flange. l2 of a dished plate l3 carried by the hub l4.

Rigidly carried by the casing l is a bearing 1 sleeve IS in which is rotatably mounted a shaft It to which the hub I4 is tightly secured. Preferably the end of the shaft and the interior of the hub are tapered and squared or otherwise furnished with interfitting driving connections, 15 and I have here shown the hub as secured to the shaft by an axial screw l1 tapped into the shaft and having a hemispherical fluted head l8 press ing on the hub. The sleeve I5 is perpendicular to the axis defined by the pivots 8-8 but is oblique to the plane defined by the rim of the casing with the result that one side of the container always prdjects outside of this rim while the otherside of the container always projects inside of this 'rim. As a consequence of this arrangement, when the casing I is tipped in one direction as shown in Fig. 1, one side of the container dips into a quantity of detergent liquid 2| with which the casing is supplied, while if the casing be tipped in the opposite direction as shown in Fig.2, the container is brought entirely above the level of this liquid, without causing the liquid to overrun the rim of thecasing in either direction. The in-' trovert or dent 5 is located close to that part of the container which dips beneath the rim of the casing, thus raising the level of the liquid relative to the container when the latter occupies its washing position as shown in Fig. 1, while lowering the level of the liquid relative to the container when the latter occupies its extracting position shown in Fig. 2. The eccentric position of this liquid-well has therefore the double advantage of modifying the height of the liquid in bothpositions of the casing, and also of reducing the tendency of the liquid to'spatter 4 or whirl during the extracting movement of the, container.

Projecting from opposite sides of the sleeve 15 are legs 22 and 23, respectively, suitably secured to the wall of the casing, and rigid with said sleeve at one side of the plane defined by these legs is a bracket 24 terminating in a threaded boss 25 perpendicular to the sleeve I5 and spaced therefrom. Threaded in the boss 25 is a horizontal bearing tube 26 having its extremity projecting through an aperture in the wall of the casing, and clamped thereto by gaskets 2i and nuts 28. Journalled in the sleeve 26 is a drive shaft 30 having. at its inner end a bevel-gear 3! which meshes with a companion bevel-gear 32 carried by and here indeed formed integrally with the hub l4. To hold the shaft it in place and to withstand the thrust of these gears the shaft is provided at its lower end with a circular metal disk 33 which overlaps slightly the end of the sleeve, which in turn is provided with a closure-cap 34 provided with a thrust-bearing such as the anti-friction ball 35.

The extremity of the shaft 30 projects through an arcuate slot 36 in the corresponding bracket 1, the bracket being formed with an enlargement 31 at one side for this purpose. Movably carried by the bracket 7 is a suitable catch for holding the shaft 30 in one or the other end of said slot 36. Said catch in the present embodiment consists of a metal plate 45 slotted at 46 for slidable mounting on rivets 41 and having a tongue portion 48 adapted to project at one side or the other of the shaft 30 according to which end of the slot 36 it occupies, thereby preventing the casing from being rocked to its other position.

A crank attachment is carried at the end of the shaft 30 by means of which the container can be either oscillated or rotated, the crank quickly coming to rest after the rotation of the container has been carried on for the desired length of time. In this part of the machine a metal'hub 50 is attached to the shaft 30 by a set screw 5| said hub having a reduced portion to which is applied a series of flat washers 52, 53, 54, all secured together by upsetting the end of the hub.

Loosely joumaled on the projecting end of the shaft is a second hub held against removal by a screw 56, and having riveted thereto a crank handle 51 and a pressed steel cup 58. The mouth of this cup closely surrounds the washer 52 which is circular and constitutes a backing plate; the periphery of the washer 53 is formed with a plurality of notches 59 having their bottoms all inclined in the same circumferential direction. Clutch balls 60 are located in the various notches in a position to engage the interior of the cup 58. A hand grip 6| pivoted for movement to the dotted line position shown, is carried by the end of the handle 51, and a longitudinally shiftable bolt 62 mounted in an eccentric boss 63 enables the crank to be attached rigidly-to the shaft 30, the washer 53 being formed with a plurality of apertures 64 for the reception of this bolt.

It will be seen that when this bolt is pushed inwardly to engage one of these apertures the container can be oscillated and this operation ing connection with the cup 58. Practically with this device it is sufficient, after setting the easing in a position to bring the container upright, to crank vigorously for a few moments until the desired speed is attained and then allow the motion to die away gradually whereupon it will be found that the fabric contents have been sufiiciently extracted.

As previously stated the washing operation may be effected by slowly turning the crank for a period of time depending upon the condition of the articles being cleaned. At the termination of the washing operation the speed of rotation 5 of the clothes container may be increased so as to distribute the clothes uniformly about the inner periphery of the container and the container may then be shifted to the vertical position shown in Figs. 2 and 5 without stopping the rotation of 10 the container whereupon the machine is ready for the extracting operation with the clothes uniformly distributed in the container so that it is substantially balanced.

The cover 2 is also made of spherical contour l5 and is provided with a depending flange portion 50 fitting inside the casing in liquid-shedding relation.

Suitable agitating provisions are furnished inside the container, the same preferably consist- 20 ing of one or more 'metal grids 5| as shown in Figs. 1 and 2, rigidly mounted in place and preferably having apertures of sufficient size to facilitate movement of the blades through the liquid but to compel all articles of clothing to move 25 therewith.

Due to the peculiar shape of the casing and its peculiar relation to the container the washing or cleansing operation can be effected with a minimum quantity of liquid. The casing being in- 30 clined to the position shown in Figs. 1 and 4, the shaft 30 is operated to impart a washing movement to the container, either oscillation or slow rotation as may be desired. With the cranklever construction, shown in Fig. '7 this is best accomplished with the handle 42 set radially as shown in dotted lines in Fig. 7, although it is possible to use the handle in the crank position shown in full lines therein, and it is possible, if the operator desires, to operate the device by 40 continuous rotation instead of by rocking. When sufl'icientwashing or cleansing action has been effected the casing is inclined in the opposite direction as shown in Figs. 2 and 5, and the handle,

now in the crank position shown in full lines in 45 dry-cleansing liquid not less than one quart nor 55 more than three quarts. Due to the small size it is easy to secure a speed of 300 to 500 R. P. M. for extracting, which is sufficient to recover much the greatest part of the dry-cleansing fluid. thereby making the device very economical. Due 60 to the friction connection between the handle and the drive-shaft, injuries due to the whirling shaft are avoided. The device is not, of course, limited to dry-cleansing fluid but soap and water can equally well be used therein for other types of 65 washing. The shaft 30 is located above the surface of the liquid in the casing thus avoiding leakage around the shaft. One way this can be assured is by locating the shaft at a level above that of the lower portion of the inclined working opening. The location of the gears inside the casing and beneath the container shields them from danger of committing injury upon the operator or on the hands of children, dispenses with the need of special housings, and enables them to be lubricated directly by the detergent fluid, the die-casting alloys from which they are preferably made being satisfactorily lubricated by most dry-cleaning fluids and by most soaps and soap powders while at the same time being free from the production of cloth-staining'products.

In Fig. 7 I have illustrated the modified crank attachment in which the end of the shaft 30 is furnished with a suitable operating lever'38 here clamped against a flange 35 on the shaft by means of a spring-washer 40 and an adjustable nut 4| to produce a friction-connection. Carried by the outer end of this arm is a hand-grip 42 for either rotating or rocking the container.
