on line 3-3, Figure 1, showing the details of the Figure 3. metal base member 6, and a die-cast apertured bo metal top plate 1. Supporting legs 6 having casters 6* are attached to the base member 6.

A water supply hose 8, may connect the machine with hot and cold water supply lines. The top plate 1, supports a. combined valve, strainer and spray nozzle structure 40. The valve and spray nozzle are arranged so that the water supplied by the hose 8, may be controlled and directed into either the washing container I, or the extractor basket 4.

The machine is provided with a pump II, the outlet of which is connected to a drain hose l2, that terminates in a gooseneck l3. The gooseneck is connected to the hose by a swivel coupling l4, and is provided for the purpose of holding the hose in position to discharge into the washer tub or elsewhere as desired. The extractor tub 2, is directly connected to the pump inlet and is continually drained by the pump during the operation of the machine. The draining of the washer tub 2, is under control of a valve l having an operating handle l6. The valve l5 has its inlet port connected to a drain opening of the washer tub and its outlet port is connected to the inlet of the pump II by means of a hose connection l5.

The top plate 1, is provided with openings l1 and i8, which register with the washer and extractor tubs, respectively. A removable cover (not shown) is provided for the tub opening l1. A cover 28, is pivotally supported in the top plate 1 on a horizontal axis adjacent to the opening 38. The opening and closing of the cover 28 stops and starts the rotation of the extractor basket 5. This control of the extractor basket is accomplished'by means of a cam 2|, which is integrally brake is automatically released, and the extractor basket is connected in driven relation with its driving mechanism.

The water and clothes contained in the washer tub are given a vortex movement by the to and fro rotation of the agitator 3, and in this manner the clothes are quickly and effectively washed.

The top plate 1 is formed with an opening 22, for receiving the gooseneck [3, of the drain hose. As best shown in Figure 2, this hole terminates in a curved lip 23, which acts as a sort of a guard or trap to prevent water escaping from the tub when the agitator is working and when the gooseneck is not in the hole. cates with the interior of the tub I at its upper part.

The water supply conduit 8 is connected by means of a coupling 24, to the portion of the L-shaped fitting 26, which extends from the side of the machine. The fitting 26 is connected at its opposite end to the top plate 1 of the machine, by means of a lock nut 26, which engages with the threaded end portion of the fitting, whereby to secure it in place on the top plate 1. The lock nut 26 also serves to hold a sleeve 21 in position in the fitting 25.

The sleeve 21 is of tapered construction and has a pair of spaced ports or

openings

28 and 30, for communication with the fitting 25. A hollow tapered valve plug 3i is journaled in the The hole 28 communimember 21. The plug has a port 32, which can be brought into registry with either of the ports of the member 21, and thus provide for fluid flow through the valve. The plug 3| is held in sealing relation with the member 21, by means of a nut 33 and washer 34, which are secured to'the threaded end portion 36 of the plug.

An integrally formed nozzle 36 and operating 'handle 31 are fixedly secured to the plug member 3i by means of a threaded rod 38 and a cooperating wing nut 48. The rod 38 is in threaded engagement with the lower end of the plug 3|, while the wing nut 48 engages the upper threaded end of such rod. A glass cover 4| is interposed between the wing nut 48 and the inlet end of the nozzle. A filter or screen 42 is held in place by the cover 4| over the inlet opening of the nozzle 36, for the purpose of preventing solid particles of dirt and foreign material from passing through the nozzle and staining the clothes. The screen 42 also serves to hold the water soluble pellets 43, which are formed from a suitable disinfecting material, and which are used to sterilize the clothes in the extractor basket. The nozzle, valve, and associated elements may for convenience be termed a spin-rinse device by reason of the fact that they may be used to rinse the clothes during the spinning or extracting operation of the extractor-container.

In Figures 1, 3, and 6, the valve parts are shown in the position they occupy when water is being discharged into the washer tub. When the handle is rotated so as to bring the nozzle over the opening of the extractor-basket, the valve plug port 32 registers with the small port 28 of the sleeve 21, and a limited flow of water is discharged into the extractor tub for the purpose of rinsing and sterilizing the clothes contained therein, during the rotation of the extractor basket. When the cover 28 is in its closed position, as shown in Figures 6a and 12, the underside of the cover is spaced above the top plate 1 a sufiicient distance to permit the nozzle 36 to be freely moved beneath the same by way of the opening between the top plate and the up-turned edge of the cover which is nearest to the nozzle when the cover is in its closed position.

The amount 01' water discharged into the extractor durlng the spin-rinsing operation is limited by the size of the valve port 28, so as to be slightly less than the maximum flow, the pump ii is able to handle. In directing the nozzle 36 to either 01' the compartments of the machine, the port 32 is brought into registry with one or the other of the

ports

28 or 30. When the end of the nozzle overlies the portion of the top plate 1, which separates its opening l1 and I8, the valve ports are in a closed position and no water flows through the nozzle 36.

The

ports

28 and 30, as is best shown in Figures 4, 5 and 6, are arranged to supply water to the washer and extractor tubs at different and predetermined rates of flow in accordance with the operations performed in such tubs. By referring to the drawings, it will be seen that water is supplied to the washer tub by way of the relatively large valve port 30 and water is supplied to the extractor tub by way of the relatively small valve port 28. Water is supplied to the washer tub largelyfor the purpose of filling the same and replenishing the contents thereof and the relatively large port 30 is provided in the valve so that these operations may be performed as quickly as possible. The capaci of the pump and the rate at which water will flow through a batch of clothes in the extfactor'basket, make it advisable to restrict the flow of water during the rinsing operation and this result is accomplished by the use of a valve port 28 which is considerably smaller than the port 30.

The nozzle 36 is provided at its outer end with a downwardly directed slotted discharge outlet 44 which extends through the end wall of the nozzle ure 3 the valve'passageways 4'| communicate with a'chamber above the screen 42 as in the form of the device shown in Figure 6. In the case of the device shown in Figure 3, however, the cover 4| is replacedby a compartmental container 48 for the reception of materials to be supplied to the water discharged from the nozzle as for example blui'ng crystals 50 and crystals 5| of a water softening compound. x

The container 48 is threaded onto the end of the rod 38 in the same manner as is the wing nut 40 and it serves to clamp a short cylindrical sleeve 52 against thescreen 42 to removably secure the screen in place. 'Predetermined and measured quantities of the crystals in the container may be fed into the chamber above the screen 42 by means ofthe

valves

53 and 54 which have operatingplunger handles 55 and 56 projecting above thetop of the container 48. The discharging of measured quantities of crystals from the container 48 is made possible by reason of the peculiar configuration of the valves 53and 54 which have annular recesses intermediate their ends so that when the valve is quickly depressed the amount of material equal'to the quantity of material in such recesses will-be discharged into the chamber above the screen 42;

By reason of the arrangement just described, when the nozle 36 is discharging into the washer tub, water softening materials can be added to the wash tub water by depressing the plunger handle 56 and when the nozzle is discharging into the extractor basket, bluing materials can be added to the rinse water by simply depressing the plunger handle 55.

The spin-rinse device just described makes it possible to perform all of the customary washing and rinsing operations on the clothes without removing the clothes from the machine. In addition to these advantages, the spin-rinse device permits the use of scalding hot water and disinfectants to sterilize the clothes.

In the modified forms of spin-rinse devices shown in Figures '7 to 11 inclusive, like numerals refer to like parts of the devices earlier described. These modifications relate in general to modifications of the strainer and the means provided for its securement, as well as the construction of the valve member, nozzle and handle as illustrated in the device shown in Figure 10;

Referring now to the modified form of device shown in Figure 7, the rod 38 is replaced by a screw 38 which is threadedly engaged in the lower part of the valve plug 3 i as in the form of device earlierdescribed. The head-of the screw 38 is received in and engages with an apertured the device.

spider 6| which bridges the passageway 60 formed in the upper part of the casting whichforms the handle and nozzle'of the device.

The passageway 60 communicates with the passageway formed in the nozzle 36 and interposed between these passageways there is provided a filter screen 62 which supports an annular filter 63 which may be in the form of a loosely interlaced fibrous material. The filter thus formed is removably held in place in the device by means of a quickly detachable cap 64 having grooved or channeled portions which receive andengage with the ends of the pins or screws 55 of the handle and nozzle part of the device. A packing ring 66 prevents the escape of water at this point,

In the form of the device shown in Figure 8 the strainer is held in place in a similar manner. The cap, however, is in the form of an annular metal ring 68 having an'inturned upper edge which engages the outer edge of a glass cap 10 and beneath which there is provided a suitable packing washer I I. This form of cap is secured to the device by the pins or screws 65 in the same manner as for the cap used in connection with the device shown in Figure 7.

In the form of the device shown in Figure 9 a glass cap 12 is provided for holding the filter in place. This filter is of slightly difierent form in that the screen has an upraised part I3 which extends across the passageway 50. The handle 74 of the device is pivoted at 75 to. the discharge nozzle so that it may be moved between the full line and dotted line positions shown in Figure 9. A ring 16 formed in the handle defines an annular opening for the reception of the glass cover 12.

Opposite to the pivot 15 there is provided a latch member I! which is pivoted to the handle at 18 and which has a catch which engages the lower marginal edge of the casting forming the nozzle part of the device. The latch is held in its engaged position by means of a spring M. A.

suitable packing washer 82 is provided to prevent the escape of liquid from around the edge of the cap 12.

In the form of the device shown in Figure 10 a valve plug 3P having a port 3'4. is integrally formed with the handle and discharge nozzle of By reason of this arrangement the holding rod 38 or screw 38 may be dispensed with as the valve parts are held together by means of the nut 33 which engages the threaded end part 35 of the valve plug. A screen 83 is fitted over the top end of the passageway formed in the valve plug part 31 A glass cover 84 having a packing washer 85 is fixedly secured to the device by means of a split metal washer 86 which is spun over the lower edge part of the cap.

In this form of the device several of the parts are eliminated and a generally simplified device 4 may be provided if cost becomes a factor of sufficient importance to offset the features of accessibility and facility for cleaning as'iliustratd in some of the other forms of the invention.

Furthermore it is to be understood that the particular forms of apparatus shown and described. and the particular procedure set forth are presented for purposes of explanation and that, various modifications of said apparatus and procedure can be made without departure from this invention as described in the appended claims.
