The Washer LB. includes airtime I that sup-ports lll l? of y Wil Q 1 9Q= ll-5 1 by means of brackets: l3. The tubulz has an agitatqr; L4 p si ioned; the ein, which ag tator in: cludes a tubular center portion 15 which is suitably journalled, andvertically positioned in the tubiand which has'a plurality of drainfhols it formed therein. 'Ifhe agitator I4 is suitably positioned for oscillatory movement in the tub I 2 and it has a stationary spray head ll mounted at its end by a tubular member ls which is positioned in the bore of the portion l5 and connests to a fluid supply source disclosedjhereinafter in more detail, cover l9fis'prqvided for the, tub l2, in order'to secure the cover in' 'position, any suitable means (not shown) may be provided for clamping the cover It 'removably o s ea on h frame h t he W6) 9 w b ain d in posi ion ven if appre i bl pressure is setup in the tulo and exerted thereon.
T n, t rm anfi p nsiblic cham r i lw thin the tub l2 for so eezing fluid from clqthes; or otherarticles in the tub, a rubber sleeve 23 is secured to the upperedge of the tub by flanges 24 en ag ng w t he tu edge an being folded back between the tub and the frame I I. A cl'amp ring M may be used also to eliminate any'possibi y of aka e albu the u per end of the sleeve 23; A frustru n -shaped member25 is ,secured to the inside of the base of the tub [.I in a removable manner, as by bolts 26, to position a lower end flange 2] of the sleeve' 2 3 in an annular recess 28 suitably formed in the tub l2.
The operation of the washer It} is automatically controlled by'a multi-section, hydraulically controlled valve 3]. The valve 3! may have a hot fluid inlet 32, a cold fluid inlet 33 a plurality of valve chambers 3.4, 35, 36 31 and 33; and a plurality of outlets 39, 4| 42 and. 43 formed therein. Waterfor other fluid supply lines 32 and 33 from the usual household supply pipes connect to the inlets 33 and 33 for supply of hot and cold fluid thereto If desired a hot and cold water mixing valve of manual or automatic type may be inco ora e i the upply n s 3 and 33. to give washing or rinse water of selected temperature." Often, however, the use of a special mixing valve is unnecessary as the washing water is employed at the temperature of the hot water supply in the household, particularly inasmuch as this temperature i's'often itself thermostatically controlled. A ball valve 44 is provided for each valve chamber and it is controlled by flngers lgi formed on disc-like members 4;!) which are'suitably secured to a flexible diaphragm member 45 mounted in and extending the length oi the valve 3!. Th'fingers'lfi are positioned in the valve3l for limited axial movement and may have packing means '(not shown) associated with them to prevent fluid leakage thereby. However, leakage of fluid from the chambers 35, 3%, and 31 is not serious since it merely serves to drain fluid from the tubular member l8 and the hydraulic motor. A plurality of control chambers M are formed in the valve 3| with one control chamber being associated with each of the valve chambers 3 35, 33, Si and 38. One extremity of each of the control chambers should be movable with relation to the remainder of the valve 3! and in this instance the diaphragm member ts is provided for such purpose, which member has individually movable sections in each control chamber. Conduits es in the valve 3! connect the inlet 33 to each of the control chambers 61 so that fliud will flow thereto and fill such chambers normally so as to move the diaphragm sections and the members it to their uppermost positions and retain the ball valves 44 on their seats in the valve chambers. For a purpose to be explained hereinafter, flow-restricting orifice members M are positioned in the conduits 5E.
The valve chamber 3 has an inlet conduit 51 connected thereto, which conduit connects to a tubular lint screen 52 removably telescoped into engagement with a drain 53 provided for the tub [2, while outlet 39 for such valve chamber connects to the main drain member 54. The valve chambers 35 and 36 connect to their common outlet ll which connects through conduit 55 to the tubular member 18 within the tub so that either hot or cold fluid can be introduced into the tub through the nozzle 17, when desired, but in some cases it may be desired to use only hot, or only cold fluid in which case one valve inlet and one valve chamber should be eliminated. Outlet 32 of the valve chamber 31 connects by conduit 56 to a suitable hydraulic motor 55 for driving the agitator is while the remaining valve outlet 53 connects by conduit 51 to a fluid pressure booster 58. The pressure booster, in turn, is connected to the enclosure 26 formed by the rubber sleeve 23 in the tub 12 by a conduit 55.
It should be observed that the valve 3! has a substantially axially directed chamber 5i therein which connects a second outlet opening 62 of the valve chamber 38 to the valve chamber 34 which is continually open through the outlet 39 to the drain 34. The ball valve is in the valve chamber 33 is adapted to seat on the outlet 62 when moved to its open position for flow of fluid from the inlet 53 to the outlet 43 and ultimately to the expansible chamber 29. However, when the ball valve is returned to its normal closed position fluid flow may, and does occur, by gravity, from the enclosure in the tub back through the booster 53, conduit 51, outlet 13, outlet 62, and chamber 55 to the drain 54.
While the present invention may be practiced with any conventional, or if desired with no, pressure booster in the fluid system used to expel fluid from clothes in the tub l2, a feature of the invention resides in use of the pressure booster 58 which automatically raises the line pressure to apply an appreciably increased force in the expansible chamber 2i In detail, the booster 53 includes an annular chamber 63 which has a suitable pressure member therein for dividing the member into two compartments, which member may comprise a pressure plate 64 that is carried on a flexible diaphragm 55, the edges of which are secured between flanges 63 formed on dished metal housings 63 and 63 used to make the chamber member 63. These flanges 63 may be secured together in any desired manner, for example, by bolts 66. The upper housing 53* of the booster 58 has a relatively small crosssectional area cylinder, or protuberance 6? formed thereon extending outwardly therefrom and it telescopically receives a similarly-shaped, apertured piston, or protuberance 68 formed on a plate 69 carried by the diaphragm 65 in fluidtight relation therewith. The member 63* has air vents 53 formed in its upper surface as the booster 58 is made to carry fluid only in its lower section, which fluid will flow through the telescoped cylinder 61 and piston 88 to the chamber 20. In order to permit flow to the cylinder 55 only when the pressure in the lower chamber section is greater than that in the cylinder 5?, and consequently that in the chamber 25, a ball valve 70 is received on a valve seat ll provided on the plate 54 in registry with the piston 68. The diaphragm 65 is apertured in the vicinity of the valve 19 so that fluid will flow through the valve into the cylinder 61, and a suitable seal ring 12 is provided on the outer end surface of the piston 58 to prevent fluid leaks from the cylinder and piston at the slidable connection therebetween. Fig. 3 clearly illustrates that the cylinder 6i and piston 68 are of relatively small area with relation to the diaphragm 85 so that when fluid is supplied to the pressure booster 58 it first pushes the ball valve Hi from its seat and flows through the cylinder 61, and through the conduit 59, which connects to the upper end of the cylinder 61, to the enclosure chamber 2% formed by the rubber sleeve 23. Such line pressure will then occasion fluid flow through the booster until the sleeve 23 is forced to the squeezing position and line pressure is built up behind the sleeve 23 in the tub i2.
During such flow of fluid to the expansible chamber 20 fluid in the tub drains from the tub [2 through the drain 53 and conduit 5| with some fluid flowing through the drain openings [5 down along or in the member l5 and back into the tub at the bottom thereof near the drain 53, as shown and explained in greater detail in my copending application, Serial No. 675,540, filed June 10, 1946, and entitled Automatic Washing Machine, now Patent No. 2,449,634, granted September 21, 1948.
As a greater compressive action on the clothes in the tub than that effected by line pressure is highly desirable in order to obtain more complete fluid elimination, the ball valve H3 automatically returns to its seat and prevents any further flow of fluid at line pressure through the valve when line pressure exists in the chamber 20. Fluid continues to flow to the pressure booster 58 due to the unequal areas on opposite sides of the diaphragm 65 exposed to line pressure. Such further flow of fluid to the pressure booster lifts the diaphragm 65 and effects relative movement of the piston 68 into the cylinder 6'! to increase the pressure exerted by the rubber sleeve 23 in expelling fluid from clothing in the tub I2. A conical return spring 73 may be positioned between the plate 69 and upper inner surface of the chamber 63 and a pin 14 is positioned in the bottom housing 63 to unseat the valve if! when the pressure supply is removed from the booster 5B and fluid has flowed from the bottom section of the chamber to drop the diaphragm to the lower part of the chamber.
The remaining outlet 42 in the valve 3! connects to the oscillatory hydraulic motor Bll for driving the agitator I4. The motor may comprise an annular housing 16 which has a shaft 11 j'ournalled therein and connected tothe agitator I 4 A vane- 18 is secured to the shaft I 'I' toform aradiall'y directed movablepartition member in the housing 16 while a pair of stationarily positi'oned partitionmembers'm are also provided in, and may be integral with, the housing. The partition-members-lsiform an obtuse angle in the housing 15 to define a Workchamber I51 therein. An inlet member 8I is positioned in. thehousing between the more closely positioned sides of the partitions. The inlet 8| has a pair of opposed chambers 82 formed integrally, or otherwise associated; with it while ports 83 formed. in. the partitions providepermanently open connections between the chambers 82 and the Work chamber I5. Then avalveshafttfl carrying spaced tandem valves 85 is provided in the housing; '85 for limited axial movement. to. control the how of fluid to and from the work chamber I5. through the-chambers 82. The valves 85 are constructed and: arranged to be moved to and from seats 86. on the inletBI so as to direct fluid: flow at one extremity of valve movement into one or the other of the chambers 82'. The valves85 also; cooperate withv and. arev moved with. relation to seats 81 formed on the; outer, or end walls of the chambers182. The valves 85 thus operate to open one of the chambers 82 for fluid input to the work chamber I5 between one partition member I9 andthevane 1:8 through the port 83 in such partition, while the port 83 in the other partition is then connected through its associated chamber 82 to the interior of the housing 16 between the adjacent walls of the partitions. Fluid within such portion of the housing 16 flows therefrom through a drain 88 to the main drain line 54..
The valve means of the motor 60 are controlled by suitable apparatus which is shown to be-lever arms 89' journalled in the housing 16 on shafts- SI. One end of each lever arm 89 is pivotally secured to an extremity of the shaft 84 while the other end of each lever has a pin 92 bearing thereon. The pins 92 are slidably positioned in bosses 93 and 94 formed in the partitions. I9 and on the housing IE, respectively. The pins 92 project into the work chamber I5 and the vane 18 strikes apin as it approaches a partition memher with the pin being moved by such vane until one-of the lever arms 89 is moved so as to. change the position of the valves 85 from one. extremity to another and reverse the flow of fluid under pressure to the work chamber. It is to be noted that the unequal areas of valves 85' and seats 36 and 8'! are important for the reasons that the. unequal areas insure positive seating of the valves 85 in either direction of movement, permit movement of the valves 85 and valve shaft 84 by pins 92 due to almost counterbalanced pressure on valves 85, and yet insure valve closing movement with a snap type of action.
As previously indicated, the control= chambers #1 of the valve 3| are normally full of fluid and this fluid retains the valves M in their closed positions; Automatic timer pilot valve: control means are provided to vary the positions of the sections of the diaphragm 36 so as to effect the desired sequence of washing operations at the proper time intervals. These meansv may comprise a housing It]! having a plurality of inletsm2 which are individually indicated by the letters which. has a plurality of. transversely directed" slotted. apertures I05, I06, I01, I08 and I09 formed 6, therein.- is journalled in': the housing; I I3 I: and. the apertures are adapted? to register; with; the". inlets I02 at. predetermined points of; rotation. of the drum m4- A. drain. conduitv I II: connects the interior of the drum; to the drain. 5&- so. that fluid will flow. from one of; the control chambers through a conduit I00 to the drum I04 and through: a: slotted. aperture" therein, when it registerswith aninlet opening I.il2,jto the drain H I.

Fig. 4 shows that there maybe a slight overlapping, of. the: drain opening with the rinse actions and, in general, it will be seen that the washing cycle can be set up on the timer control as. desiredfor any given Wash condition. Then the speed of drive. for the rotor drum may be manually'altere'd in any special manner to change the predetermined wash cycle.
A manually-adjustable shut-off valve 68 positioned. in the conduit 58. i usually employed in that by adjusting the valve the speed of the hydraulic motor til can be adjusted. This is important in that fineclothes. can be washed, at a slower agitating: speed than ordinary clothes. In fact, a Wide range of agitating speeds. are readily obtained.
If found advisable in certain installations, for example, farm use, an electric or other motor and pump can be incorporated with the apparatus in association with the supply lines 32 and 33 to provide a constant pressure fluid or water supply to the apparatus. This makes the apparatus independent of fluctuating or no water line pressure.
It will be noted that various features of the washer disclosed herein are suitable for use in other manners than that described since the pressure booster, motor, inulti-section valve, and the valve timer, may be used separately in other hydraulic apparatus. However, their combined action produces a relatively inexpensive automatic washer which has a minimum of parts and is adapted for a long period of use without any service requirement. Hence a dependable allhydraulic automatic Washer is provided and the objects of the invention are achieved.
