WASHING AND WRINGING MACHINE Application med september 29, 1922. serial No. 591,401.

To all whom t may concern.'

Be -it known that I, FREDERICK A. BARNES, a citizen of the United States, residing at Cleveland, in the county o f Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Washing and Wringing Machines, of which the following is a specification.

The present invention relates to power driven washing and wringing machines and,

particularly to washing and ringing machines of the type wherein the washing'is performed by one or moresuction cups or bells which are reciprocated vertically and at the same time given a step by step rotary motion around the tub containing the material to be washed, and the wringing is performed by a suitable wringer which may be carried by the frame of the machine. The washing mechanism and the wrmger are usualljy driven by a small electric motor Vand my' invention relates particularly to a machine so driven, but it will be understood that it is not necessarily limited thereto, nor is it as to certain aspects limited to the specific type of washing mechanism referred to above.

The' object of'my invention is to provide an improved washing and wringing machine and for al consideration of what I believe to be novel and my invention, attention is directed to the accompanying description and the claims appended thereto.

Infthe drawing, Fig. 1 is' a verticall sectional view of a machine embodying my invention. the section being taken on line 1 1,

Fig. 1: Fig. 6 is an enlarged detail view of certain parts, and Fig. 7 is a sectional view taken on line 7 7, Fig. l.

Referring to the drawing, 10 indicates a housing or' easing which is entirely closed and which contains the operating mechanism of the' machine. In the ltop of housing 10 is a largeiu opening 11 of somewhat ir' regular outline as shown in Fig. 2 and a smaller' circular opening 12. Opening l1 is defined by an upwardly-projecting neck 13 surrounded by a Harige 14 having a flat to surface. Housing 10 is provided at one l si el and adjacent its top with an outwardlyprojecting portion 108 having an opening 15 in its topwall defined by a thickened sleeve 16. Opposite opening 15 the bottom wall of portion 10al is provided with a thickened section 17 in which is a recess 18. Directly beneath thickened section 17 is a leg 19 of the machine. Leg 19 is formed integral with the bottom ;wall of portion 10il and thickened section 17 and is joined to the main housing wall by webs 20. Journaled in recess 18 is a stub shaft 21 which carries a worm wheel .22. Stub shaft 21 has an axial opening in which is fastened the lower `end of a. vertically-extending wrin r shaft `the lower end of a stationary shaft 26, the

end of the shaft having threaded enga ement with the bottom of the socket as in i-` cated at 26B. Mounted on shaft 26 is a sleeve or shaft 27 which extends thel entire length of the shaft and is adapted to turn thereon,

the sleeve being held between the top surface of pedestal 25 and a head' 28 on shaft 26. On the lower end of sleeve 27 is a eylindrical-cam 29 which is preferably formed integral therewith 'and has a continuous outwardly-facing groove 30 which forms a cam track. On sleeve 27 just above cam 29 is av sliding clutch member 31. It is keyed to the sleeve so itturns therewith and can move vertically on the sleeve between a lower shoulder 32 and the under surface of a worm wheel 33. Worm wheel 33 rests against a shoulder 34 on sleeve 27 and can turn freely thereon. Clutch member 31 h s one or more upwardly-projecting. vpins 3 adapted to enter openings 35a in the web of worm wheel 33. When in the position shown in Fig. 1 of the drawing it will beseen that the clutch member connects worm wheel 33 to sleeve 27 while when the clutch member is moved downward againstshoulder 32, pins 35 are withdrawn from openings 35'i and the worm wheel can/turn freely on sleeve 27. Keyed to sleeve 27 above worm wheel 33 is a hub 36 having a locking segment 37 and anarm 38 which carries an actuating pin 39.

At the right hand side of housing 10 and in line with smaller openingV 12, the housing wall is shaped to provide a vertically-extending guideway 4() which is nearly a complete circle in cross section as shown in Fig. 5, there being a vertically-extending slot 41 which faces toward the center of the housing. In the inner surface of guideway are a number of spaced verticallyextend ing keyways 42 which terminate short of the top of the guideway as indicated at 43. At its upper end guideway 40 is provided with an enlarged head 44 which provides a shoulder 45 and mounted in head 44 and on shoulder 45 is a hub 46 to which is fixed a stop index wheel 47. Hub 46 can turn freely in head 44 and is provided on its inner surface with keyways 48 of the same size and number as keyways 42. Stop indexwheel 47'is provided in its periphery with spaced actuating slots 49 adapted to be engaged by actuating pin- 3.() and with locking grooves 50 adapted to .receive locking segment 37 Slots 49 have the same angular spacing as do keyways 42 and 4,8.

Projecting into housing 10 through smaller opening 12 is a plunger rod 51 having a collar 52 pinned to its lower end which collar serves as a support for a-sleeve 53 mounted on the plunger rod. At its lower end sleeve 53 is provided with integral keys 54 which'l slide in keyways 42 and with a pin 55 which projects through slot 41 and carries a roller 56 which runs in cam groove 30. Pinnedto plunger rod 51' just above sleeve 53- is an indexing collar 57 having integral keys 58 which run in keyways 42 and are adaptedto enter keyways 48. Sleeve 53 is held between . collars 52 and 57 so it cannot move vertically relatively to rod 51, thev ro'd being, however, free. to turn in sleeve 53. Opening 12 is provided with a suitable stuiiing box for rod 51, the same being shown as comprising a plug 59 which 1 .ts opening 12 and is4 provided with ya counterbored opening into which screws a nipple 6() for compressing a gasket 61 around rod 51. Both the plug and the nipple have flanges which serve-to divertany 5;) water which may fall on theln so as to prevent 'its entering housing 10.l

Housing 10 is shaped'to provideV a projecting portion 62 to accommodate wheel 47 an'd just below this is a cylindrical extension 6.3 having a--flange 64 to which is bolted a flange' 65 on the casing of an elecl tric motor 66. Between flanges 64 and 65 is an insulating ring v67 and surrounding the fastening bolts 68 are' insulating sleeves 69 so that the motor casing is entirely insulated from housing 10. insulating ring 67 is provided with an extension 67 which forms a dam to keep oil from getting to the ,moton In extension 63 is a web 70 which forms a support for a bearin0-71 and on the opposite side of the housmg is a seciaosee ond support 72 for a bearing 73. Web 70 is provided with a drain opening 70a. Mounted Lin bearings 71 and 73 is a shaft 74 which is connected to the shaft of motor 66 by a slip coupling 75. Slip coupling 75 may be of any suitable structure and is preferably insulated from shaft 74. Its function is. to protect the motor and the machine by slipping in case of overload onl'the machine. Mounted on shaft 74 is a worm 76 which meshes with worm wheel and a worm 77 which meshes with worm wheel 22. Formed integral with worm 76 is a lthrust collar 78, between which and a ring 79 which loosely surrounds shaft 74, are balls 80. Ring 79 binds against the end of bearing 7 3 so that the ring is held from turning. This forms a ball thrust bearing to take the axial thrust of shaft 74.

Formed integral with housing 10 are two 1 radially-extending arms 81 at the outer ends .of lwhich are supporting legs 82 preferably formed intgeral with arms 81. There are -thus provided three legs `for the machine spaced 120o apart. Arms 81 are each provided with pads 83 which lie in the same horizontal plane as does flange 14 and resting on these pads and flange 14 is a circular cover plate- 84 having a downwardly turned, rolled edge 85. Cover plate 84 is fastened to pads 83 by bolts 86-and to flange 14 by a ring 87 which conforms to the outline of opening 11 and is fastened in place by bolts 88. This serves to form a tight cover for opening 11 to prevent the entrance of any Vwater into housing 10. Cover plate 84 has an opening 89 in it to li, hten` the structure. ing 15 is a frame tube or post 90 and over each' leg 82 is a frame tube or post 91. The upper ends of the frame tubes 9() and 91 serveA to support a top ring 93, which is attached to them in any suitable manner. The lower ends of tubes or posts and 91 are suitablv attached to the rolled edge 85 of plate 84. The tubes or posts 90 and 91, top ring 93 and cover plate 84 thus Fixed at its lower end in openform a frame in which tub 94 is mounted.

``Wringer shaft 23 extends throughv tube 90 vtop of tube 90 so it may swing in a horizontal plane and will be provided with a .suitable reversing gearing so it may be run 1n either.. direction, this being a 'known wringer arrangement.- It will be noted that v the wringer is mounted directly over leg 19 so ,it'has a firm support, the weight belng taken by housing 10. A

- Mounted in the frame formed by posts 90 and 91 and ring 93 is a tub 94 having a cover plate 95. Tub 94 rests on cover plate 84 and is fastened to 'it at its center by 'a tubular post 96. Post 96 has a flange 97 which rests on the bottom, of the tub and an extension 98 which projects through holes in the tub andcover plate and is threaded on its end .to receive a nut 99 to clamp the tub to the frame and the post i.in position. This arrangement serves to tirmly clamp the tub to housing and provides a tight joint at the point where post 96 passes through the bottom of the tub.

Plunger rod 51 extends up through post 96 and carries on its upper end a yoke 100. At the ends of the arms of yoke 100 'are mounted suction cups or bells 101 which di- 4 reetly perform the washingv operation in a well-'understood manner. At the upper end of post 96 is a suitable stuffing box 102 to prevent water from leaking down between the post and the plunger rod. On plunger rod 51 is a downwardly-sloping collar 103 which serves as a' Watershed to prevent water coming into contact with the top of nipple where plunger rod 51 passes through it. Collar 103 is located at such a point on rod 51 that when the plunger'rod is at the bottom of its stroke the collar standsjust above the top of the nipple. During the' upstroke of the plunger rod collar 103 passes up into post 96. Preferably plunger rod 51 is made in two parts threaded together as indicated at 104 iii Fig. 1 and water shed collar 103 is in the form of a washer held between the two parts ofthe plunger rod. It will be noted that at the point where the end of postl 96 passes through the cover plate the housing is. provided with a depression 96a which forms -a recess outside the housing for the reception of nut 99. By this arrangement the connection is brought outside the housing so that any leakage down around 'the plunger rod 51 will fall onto the top of the housing.v

Clutch inenlie'r 31 may be'operated-in any suitable manner lfor connecting sleeve 27` In the present instance' to worm wheel 33. it is shown as being provided with Van ani nular groove 105 which receives pins 106 on the vtorked end of a lever'arm 107. Lever arml 10T is fixied'tothe inner Aend of a shaft 108 ljournaled in hearing sleeves 109 in the fwall 'of housing 10.' )n the outer end ot j shaft 108 is lirzed, a lever arin 1*' 10 which at 'its free end hasA an angular-lyl turned' gear 'sector 111. It will be clear thathy raising and lowering the free -endvof arin 110 the'.l

clutch member will be thrown out' of and into engageniet with wornnwheel 433. `rFor actuating' -ardn'i 110 I provide a rod 112 hav-- ing gear teeth at its lower end which mesh with thefteeth on gear sector 111. Rodv 112 ing the wringer sha-ft 23.

extends up through adjacent. frame tube 91 and is provided at its upper end with asuitable .handle (not shown) for raisiiig'and lowering` v.the rod. To hold the clutch inem-` ber in in and out positions arm 81 .is provided with a downwardly-projecting web 113 having a hole in which a springpressed ball'114 is located `and lever arin 110 is provided with'a pad 115 having' two spaeedfshallow recesses 116 with Which balll 114 engages. This fo-rms a yielding means for holding the clutch lin eitherjof its two positions. Housing 10 contains a suitable supply of oil lfor lubricating the machine, the oil level being indicated at 117 in. Fig. 1.` Cam track 304 and the moving v-parts carried by the. lower end of plunger rod 51 dip into the oil during operation so they are directly lubricated. For carrying lubricant up to the worms and worm wheels any suitable means may be used. In the present instance shaft 74 is provided at its one end with an inipeller 118 which riuisl in a casing 119, closed y a cover plate 120. The suction opening of 'easing 119 'is' connected by a pipe 121- to the oil supply in housing 10. Connected to the discharge openingof casing 119 is a discharge pipe 122 which extends along the top' of shaft 74.4 The end of pipe 122 dis- S cl'iarges oil on worm 76 and Worm wheel 33 and the pipe is provided withone or. more holes 123l which discharge oil to worin. 77

been placed in tub 94, motor 66 is started by closing its ciicuitvthereby driving shaft 74.

Assuming thatclutch meinbe r\\31 Iis in out position worin wheel 33 will be turned idly on sleeve or shaft 27 by worm 76, and worm wheel 22 will-ble turned by Worin 77 thus drivy lVringer shaft 23 is driven continuously whenever the motor is running and may be connected to' the wringer4 mechanism (not shown) in a wellknown-inanner as already referred to. If clutch member31 is'now thro-wn to .in7 position, i. e., tothe position shown in Fig. 1,.

worm wheel 33 will be clutched to sleeve 27 .and will rotate itl on stationary shaftV 26'.

This will turn cylindrical cain 29 and as the cam groove 30 moves relatively 'to roller 56 plunger rod 51 will he raised and'lowe'red once for each ,revo lut.ior iv of the'cain. This impartsl reciprocating movement to suction cups orbells 101'.- Dining-"all enceptthe ex 4treme upper .limit of its reciprocatingmovenient` plunger rod 51? is positivelyheld from turning on fits `vertical axis bythe engagementlbetween the keys on indexing'eollar 57 and'keywa-y's 42.;- `*Sleeve 53 is lheld from turning byV the engagement-'between keys 54 and -keyways 42. VAlso stop index wheel y47 is .held stationary by locking' segment 37 ian V which lies in a groove` 50. When lunger rod 51 reaches the top of its stroket 1e keys on indexing collar 57 pass out. of keyways 42 and enter keyways 48 in ,hub 46. At this time locking segment 37 leaves the groove 50 in which it has been turning and actuating pin 39 engages the next adjacent slot 49 and turns wheel 47 an angular distance equal to the distance between slots 49. Locking segment 37 then engages in the next groove 50 to again lock the indexing wheel 47. At the time indexingv wheel 47' is being turned by pin 39, hub 46 is locked to plunger rod 51 by indexing collar 57 so that the turning of Wheel 47 effects a turning ofplunger rod 51 and suction cups or bells 101. Keyways `42 and,.48 and slots 49-have the same angular spacing so that keyways 42 and 48 are brought into alignment after each turning movement of wheel 47, and are locked there. 'Since pin 39 and segment 37 turn directly1 with cam 29, the suction cups 101 will be given a turning movement at the top of each stroke. The extent of. this movement depends on the angular spacing of keyways42 and'48 and slots 49. Preferably I employ v an odd number ofkeyways and slots so that the suction cups in being turned step by step will be brought dbwn'cach in dilferent places, the vertical paths taken by one cup during a complete revolution of the cups being midway between the vertical paths taken by the other cup. For example, in the present instance there being nine keyways 42 and 48 and nine slots 49, for oney cup 101 to be moved through 180 degrees to the yposition occupied .by the othercup, i. e., half way around, lwould require four4 and onehalf indexing movements which means of course, that on the fourth indexing movement it would be 20 degrees behind the position formerly occupied by the other cup and 0n the fifth indexing movement it would be 20 degrees beyond such position." This in sures that the suctioneups in their travel will cover the entire surface of the material beine washed.L y

With the above-described arrangement it will be seen that the suction cups are Dositively locked againstl turning movement during all their strokes except at the upper en d thereof when they are released and positively turned' through a definite angle. By this arrangement it is insured that the suction cups rare only turnedwvhen they are above the Water-line in the tub thereby doing away with the possibility of the cups setting .up a revolvlng of the clothes in the tub and wrapping of *the clothes around central post 96.

The use of a cylindrical cam for e'ecting.

reciprocation of the plunger mechanism is of advantage in that its use results in a very.

simple mechanism which is easy to build and not likely to get out of order. Also by shaping the cam variable speed can be impartedto the` suction cups during their lrciprocating movements. Forexample, the

the cups through the clothes, or it may beI shaped to vproduce other variations in speed suchas may be found desirable.

The provision of separate worms 76 and 77 for driving the washingmechanism and the wringer respectively is of advantage vin lthat `it provides for direct drive for the wringer shaft Q?) without the interposition 'of bevel gearing. This is important because the maximum power is used in operlating the wringer, 'the washing mechanism requiring but'a small amount of power in comparison with the Wringer.

It will be noted that all the operating n'iechanism for'the machine is entirely enclosed in housing 10 so it is protected and can be perfectly lubricated. There are no openings in the housing through ivhieh leakage of lubricant is likely to occur which permits of putting a supply of Voil directly in the bottom of the housing from whence it can be carried to all parts which are-subject to wear. The possibility of oil getting vto motor 66 is vprevented by dam 67"1 and any oil that gets into casing extension 63 can run out throuvh drain -opening 7 0a.V

The making of housing 10 andthe legs of the machine as one integral structure in which all the operating mechanism is enclosed and supported facilitates manufacture as with multiple spindle drills and similar quirement for any special fitting is elimiy nated. Also in this arrangement since all the operating parts are arranged in4 andcarried by the, housing which in turn is supported directly on the floor practically all the' Weight is taken off the frame of the machine, no parts being supported o'n the underside of the frame. All the reactions due to the moving parts are taken by -housing` 10 and not bythe tub or frame. In other words, instead of the supporting parts for the actuating mechanism being carried by the tub and frame, theyare all carried by a single housing which also supports the tub and frame. I

In assembling the machine, the housing 10 with its supporting legs, which together form a self-contained, self-supporting structure which can be handled as a unit is first;

machine is assembled therein, including the plunger rod 51. v-This portion of the machinemay be then tested as a unit and all the Ioperatingpar'ts properly adjusted. Fol.

lowing this, the frame which includes posts its true operating position.

90 and 91, top ring 93 and plate 8 4 and which has already been' assembled is put -into place and fastened vto lthe lop of the,l housing. And, last, the tub 0i is -put into the frame and fastened therein byputting't'ubular post -96 into place and fastening it by nut 99. Thus it 'will be seen thatthe machine comprises essentially'three parts or units, viz, the housing which is supported by the legs and which contains all the operating mechanism, the frame, and

thetub. This arrangement is important from a manufacturing standpoint 111 that it enables the operating mechanism to be assembled in the housing and tested without having to assemble the whole. washing machine. The arrangement also facilitates inspection and repair of the machine in that by removing the tub andthe frame, the operating mechanism is exposed and appears in In other words, the operating mechanism can be gotten at without having to remove any of it `from the machine.

It is important that no water be permitted to find its way into housing 10 as it would tend to emulsify with the oil thus reduring its lubricating qualities. The leakage of water into the housing around plunger rod 51 is prevented by water shed 103 and the ianges on plug 59' and nipple 60. Any water which leaks through stutiing'box 102 and runs down the plunger rod willy be deflected outwardly by the water shed and the flanges and run off the top of the hous- Iler'tain features disclosed in this application are not claimed herein as they form subject matter of and are claimed in the copending applicationv of George E. Randles, Serial N o. 591,400, led of even date herewith and whose assignee is the Foote-Burt Company.
