. 7 Claims. (Cl. 68-25) This invention relates to washing machines of the type wherein the clothes to be washed are placed in a rotatable cylinder or the equivalent normally partially submerged in water and which cylinder, with the clothes contained therein, may be moved to a position above the water and turned at a relatively high speed to effect centrifugal drying of the clothes, the principal ob- `iect being the provision of a washing machine of the type described that is simple in construction, economical to manufacture and efiicient in operation.

Objects of the invention include .the provision of a washing machine of the type described in which the washing cylinder or its equivalent is mounted for pivotal movement with respect to the co-operating tub and is arranged as a unit with driving mechanism therefor, the driving mechanism being so positioned and supported as to tend to counterbalance the weight of the washing cylinder and its contents; the provision of a washing machine of the type described including a tub and a bracket pivotally mounted thereon, the bracket rotatably supporting a shaft and the shaft in turn supporting the washing cylinder normally within the tub, the bracket also supporting a motor and means for connecting v mechanism; the provision oi a washer of tli'eftype described including an imperiorate member surrounding the washing cylinder in generally spaced relation with respect thereto and movable bodily with the washing cylinder .in its pivotable movement about the `axis of the aforementioned bracket; the provision of a construction as above described in which the guard is provided with an open corner whereby when the washing cylinder is. swung to a vertical position for wringing purposes the water discharged from the clothes in the cylinder is directed back into the tub; the provision oi.' a construction as above described in which the shaft which supports the washing cylipder projects through one end wall oi' the tub and such end wall is cut away to permit swing-` ing movement of the shaft therethrough, the guard Vfor the washing cylinder including an end wall `co-operating with the cut-away portion of the end wall o! the tub to seal the same against loss of water during washing operations; the provision of a construction. as above described in which the guard includes a side pivotally secured thereto and co-operating with the top edge oi' the tub when the washing cylinder is in its nor.- mal'washing position to close the top of the tub; the provision of a construction as above described in whichl the washing cylinder is provided with an open end to permit reception and discharge of clothes therethrough, together with a closure for the open end of the washing cylinder mounted on the guard and movable to and from operative relationshipwith respect tothe open end of the washing cylinder; the provision ofv a construction as above described in which the positioning of the closure for the open end of the washing cylinder is a 'condition precedent to placing the washing cylinder in a position for normal washing movement; the provision oi' a novel drive structure for the washing cylinder permitting the same to be driven at dierent rates of rotation for washing and wringing purposes: and the provision of a novel drive mechanismincluding speed change mechanism in the drive to the washing cylinder operated automatically as the washing cylinder is moved between horizontal and vertical positions to drive the cylinder at low g oi-.high speeds.

L: The above being among the objects of the present invention the same consists in certain novel features of' construction and combinations of parts to be hereinafter described with reference to the accompanying drawings, and then claimed. having the above and other objects in view.

Referring to the accompanying drawings it will be noted that the washing machine includes a tub indicated generally at I of more or less U-shape in transverse cross-sectiomhaving a front end wall I2 and a rear end wall I4. The tub is supported from the noorby means of a leg structure 'including-a sheet metal skirt I6 which surrounds the tub and is secured to the opposite side thereof along a line slightly below its center. The skirt 1s et the from; end or the tub is arrangedv m i nush relationship with respect to the forward end I2 but at the rear end it extends rearwardly of the rear wall I4 and is provided with tapered side extensions Il lying generally in the plane of the outer sides of the tub and provided with inwardly turned marginal flanges 20, best shown in Fig. 4, for stiftening purposes. Feet 22 are formed at the four corners of the skirt I6 adjacent the lower edge thereof. the legs 22 serving to iixedly support the tub I0 from a floor and preferably being provided with knobs, rollers, casters or the like 24 permitting the tub to be moved from place to place upon a floor. AdJa- -cer.t its forward end the tub I0 is provided with a. drain valve 26 in its bottom for the purpose of permitting the liquid contents of the tub to be drained therefrom in a conventional manner.

As best illustrated in Figs. 1 and 4 a relatively heavy bracket 30 is suitably xed as by riveting, welding, brazing, soldering or the like to the outer face of the rear Wall I4 of the tub IU, the bracket extending substantially the full width across such rear face and having a marginal forwardly turned ange portion 32 embracing the adjacent margin of the side and bottom walls oi" the tub I0, the bracket thus being rigidly and immovably secured to the tub. The bracket 30 isl bracket 38 rotatably suppcritherein a shaft 42` disposed with its axis in a` plane' perpendicular to the axis of the pin 40 and normally lying in a horizontal plane as illustrated in 1. The shaft 42 projects to a point interiorly of the tub III and, for the purpose of permitting such projecting end of the shaft 42 as well as parts to be hereinafter described and carried by the shaft 42 to be movedI therethroughthe rear wall I4 of the tub is cut Y away as best indicated'at 44 inFig'. 4 along a ho'rf form, it is preferably, and is so shown by way of illustration, in the form of a perforate washing cylinder 50 the 'righthand endwall 52 thereof, as

viewed in Fig. 1, is rigidly fixed to the ange of the hub 48. The opposite end of the washing cylinder 50 is inwardly flanged as at i4 a short distance so as to leave a circuler opening therein through which clothes may be introduced into the interior of the washing cylinder 50 and removed therefrom. The washing cylinder 50 is preferably provided interiorly thereof with a plurality of transverse vanes or bars 56 for the purpose of enabling greater agitation of the clothes during rotation of the cylinder 50 as will be readily understood by those skilled in the art.

The rear end of the bracket 38 is peripherally enlarged to form an annular flange 60 winch serves 'as a closure for the open end of, and to support, a housing or casing I2 nxed thereto. The housing i2 enclose; a second housing comprising a cup-shaped member 64 fixed against relative rotation to the righthand end of the shaft 42, and, a cover portion It provided with a hub which is iournaled inthe housing member 62 centrally thereof. The cover Il rotatably supports centrally thereof a sha'ftll, independent of the shaft 42, and which projects outwardly to the right, as viewed in Fig. 1, and there carries a driving pulley 18. As best brought out in Figs. 1 and 5 the shaft il has fixed to its inner end within the casing 64-66 an eccentric 12, and rotatably mounted upon the eccentric 'I2 is a spur gear 14. The inner face of the housing member 84 is formed to provide an internal gear I8 which lies in mesh with the spur gear 14. 'I'he above described arrangement forms a conventional form of gear reduction mechanism the reduction ratio of which is equal to the difference in number of teeth between the internal and the external gear divided by the number of teeth on the driving gear. In the present case it is assumed that the gear I4 will have twenty teeth and the gear II twenty-two teeth. giving a reduction ratio of one to ten.

In order to render the above described reduction gear mechanism inoperative when it is desired to drive the shaft 42 at the same speed as the shaft 68 the following mechanism is provided. The hub of the member 66 projects to the right past the end of the housing member 62 and such projecting end is axially notched as at 80 in Fig. l. A peripherally grooved sliding dog clutch member 82 is axially slidably but relatively nonrotatably mounted upon the righthand end of the shaft il and is provided with teeth 84 which are engageable with the notches 8l in the member 86 when the dog member is moved to the left, as viewecrm Fig. 1. when the dog clutch member l2 is in the position indicated with the teeth 84 out of engagement with the notches 8U, the shaft II may turn relatively to the housing 84-4 and consequently the .reduction gear mechanism is operative. However, if the dog clutch member 82 is shifted to the left to bring the teeth I4 into` engagement withthe notches 8l, then the shaft il and 1101181118` 64-88-'are locked together for equal rotationV Consequently in the latterposition of these parte the shafts se and u are kicked toeetnerrcrequai rotation and the washing cylinder 50 'will rtateatfthe' l there pivotally connected to one end of a rigid link B3 the opposite end of which is pivoted at 83' to one of the eyes 34 of the bracket 30 at a point spaced upwardly from the axis of the pin submergedY in the water f eXtent .-the Weight vertical position; as'

asoaom 40. The pivot point 83'vis so arranged that the teeth of the clog clutch member 82 are out of engagement with the notches "when the cylinder 50 is in horizontal positionbut are automatically brought into engagement therewith when the cylinder 6U is moved .to vertical position. 'I'his vis not only a convenience but also a safety feature as it prevents the cylinder El! from being turned at high speed when partially in the tub.

In4 order to drive the shaft 68 an electric motor 90 is mounted upon 'a suitable bracket 92 vformed 'integrally with the bracket 38 and is provided with a driving pulley 94 connected by a belt 86 with the pulley 10. The pulleys 94 and 10 afford an additional means whereby 'a further reduction in the drive between the motor -90 and the shaft 42 `may be obtained cylinder 50 and the designer. In the smaller sizes of washers adapted for the needs of the average small family, it will ordinarily be desirable to turn the washing cylinder 50 approximately 80 R. P. M. during washing operations and 800 R. P. M. during wringing operations. 'Thus where the electricy motor 80 is of the conventional type turning 1780 R. P. M. per minute the ratio between the pulleys and 9d will preferablybe a ylittle more than 2 to 1 where a gear. reduction mechanism oi the ratio described is used 'in conjunction therewith.

With the construction thus far described it will be understood that the bracket 28, which is pivoted at 40, carries the washing cylinder 50, the gear reduction mechanism described and the electric motor 90 and consequently all of these parte may be pivoted as a urlt about the axis o the shaft 5S. The bracket 3B preferably cooperates with the bracket 38 in such a manner that when the parts are swung to the position indicated in full lines in Fig. l, that is when the bra `et 38 is moved in a countercloclrwise direction or" rotation as viewed in Fig. l, downward movement of the bracket and parts supported thereby will be limited to a position in which the washing cylinder 50 is positioned with its axis substantially horizontal as indicated. In such position of the parts it will be apparent from an inspection of Fig. l that the weight of the motor 9|! and the gear reduction mechanism and driving means therefor are located primarily to the right of a vertical plane including the axis of the pivot pin 40 and consequently serve to counterbalance .to a greater or lesser or the washing cylinder 50 and any contents the;eof. Whenthis unit is swung to bring the axisof the washing cylinder into a in Fig. l, l't will `be understood that because of the fact the axis of the pivot pin 40 is below the axis o the shaft` 42when the unit is swung to vertical position the bulk of the weight will be to the right of the pivot pin 40 and consequently will tend to maintain the unit in vertical position. Contact of the a'nge 60 with the bracket 30 may be employed to limit movement of the unit about the shaft 40 in a clockwise direction as viewed in Fig. l. Additionally, it may be desirable, under certain conditions at least, to provide means for latching the unit in vertical position and in Fig. 6 one means for effecting this result is shown. This comprises a spring arm 200 fixed to the bracket 3l! and extending perillustrated in dotted lines yprojection 202 pendicularly outwardly therefrom, the free end being formed to provide an inwardly extending adapted to resiliently co-operate with a notch, such as 204, in the flange 60 o! the bracket 38 when the unit is swung to vertical position. `The arm 20d being formed ot spring material, the end |02 will automatically drop into the notch 204 when brought into matching relation therewith, and when it is desired to return the unit to normal horizontal position, a iirm pull on the unit will cause disengagement ot'lthe arm 200 and notch 204 to permit such movement;

It will be appreciated from the above `descrip- -jtionthar m operation, when it is desired townsh if desired. It will be understood that the speed of rotation of the shaft.

42 both in normal washing operation and wring.- ing operation may vary upon the size of the-` deslres of the individual g 'or the part some clothes or other articles,

terior thereof and it/is then returned lto vthe horizontal position indicated in :uu lines in Fig. `1, the dog clutch 82 being withdrawn from interengaging relation with respect to the notches 80 the'lower part of the tub l0 but to a. point below 'the'upper `edge of the cut-away portion 44 of the rear wall I4 of the tub. The motor 90 is then energized to cause it to drive the shaft 68,

' and the shaft es through the gear reduction mechanism described drives the shaft 42 and consequently rotates. the washing cylinder. The perforations in the cylinder 50 permit ready iiow of the water into and out o! the washing'cylinder and the bars 56 constantly turn the articles through the water and agitato them therein in order to effect the desired cleansing' thereof.

When the washing of the articles is completed,

then either one of two different steps may be followed. The lirst of these would be when the articles in the washing cylinder 60 constitute the entire wash, in which case the soapy water may be drained through the valve 26 and replaced by rinse water, whereupon further rotation of the washing cylinder may be effected to thoroughly rinse the articles. After the rinsing operation or in event there are more articles to be washed in the soapy water, the cylinder 50 is swung up into vertical position, the dog clutch member 82 being moved to lock out the gear reduction mechanism by such movement, and the cylinder 50 is then whirled at a relatively high speed to centrifugally discharge the water from the articles. Where it is the soapy water that is thus discharged fromthe articles being washed, they may be removed from the cylinder and accumulated until the entire washing is completed in the soapy water, after which the soapy water may be withdrawn from the tub and replaced by rinse water and all the articles then replaced in the washing cylinder 50 in desired 'sized lots triiugal drying step. In either eventit will be understood that when the cylinder 5U is movedv from horizontal -to vertical position it is not necessary to lift the water in the tub `vith the cylinder, as the only water which requires lifting will be that absorbed by the clothes, the .remainder simply running out of the cylinder and staying in the tub. Furthermore, during such movement of the cylinder, the clothes therein will tend to .fall to the bottom end of the cylinder Sil, thus lessening the amount of work required by the housewife in raising the cylinder and increasing the counterbalancing eiect of the motor and drive.

It will, of course, be understood that with the construction thus far described, during the cen- 68. soapy water is introduced into trifugal drying process the water would be discharged from the washing cylinder E without restraint and very little if any would be returned to the tub. In order to prevent this, as well as to provide certain other advantages in the construction described the mechanism includes the following additional parts. An imperforate sheet metal guard member |00 of substantially the same general cross-sectional conformation as the tub I0 is positioned within the tub |0 and in surrounding relationship with respect to the cylinder 50, it being of substantially although slightly greater length than the washing cylinder 50. The guard |00 at its upper edge is provided with an outwardly turned marginal flange overlies and which rests upon the upper outwardly fianged marginal edge of the tub I0 when in normal position for a washing operation. The guard |00 is open at its lefthand end as viewed in Fig. l, but is provided with a rear or righthand end wall |04 formed integrally therewith and which extends to the top thereof. This rear wall |04 is suitably xed in water tight relation to the ange |06 on the bracket 38 and when the washing cylinder 50 is in its normal horizontal washing position such rear wall |04 bears against the inner face of the rear wall 4 of the tub l0 and provides a water seal at this point to prevent`escape of water over the upper edge of the cut-away portion 44 of such rear wall |4. At its rear edge the wall |4 is provided at its opposite sides with an outwardly directed flange |08 and the tub |0 at each of its opposite sides is provided with an inwardly projecting co-operating flange ||0, lying to the left of the ange |08 as viewed in Fig. l, and in a position so that the co-operating flange |08 will bear against it when the cylinder 50 is in its normal horizontal washing position to provide a water seal along the sides of the tub. The flanges |08 extend downwardly to a point lying approximately in a horizontal planeincluding the axis of the pivot pin 40, so that there .will be no interference between the flanges |08 and ||0 when the washing cylinder 50 is swung upwardly into vertical position.

The upper side of the guard |00, when in horizontal position, is closed by a cover member ||2 pivotally secured to the rear wall |04 thereof. The cover ||2 which, of course, is imperforate, co-operates with the flange |02 around the upper edge of the guard |00 and with the upper edge of the tub |0 to also provide a closure for the tub |0 when the mechanism is in its normal washing position A handle I4 is preferably provided to aid in manipulating the cover ||2.

The guard |00 adjacent its lower righthand end as viewed in Fig. 1 is cut away as indicated at ||8 in Figs. l and 3 to provide an opening of relatively large size therein. When the tub is swung up into vertical position the opening ||6 is vertically within the opposite end walls of the tub |0 and materially below the upper edge of the tub I0. The guard |00 and its cover ||2 being imperforate, all water which is discharged from the washing cylinder 50 during a centrifugal wringing process is caught by the guard and its cover and drained downwardly by gravity therein and discharges through the opening ||6 back into the tub I0.

In order to close the open lefthand end of the cylinder 50, as viewed in Fig. 1, during a washing operation, the following mechanism is provided. A strap-like member is pivoted at |22 at one end to the open end of the guard |00 at |02 which the lower forward edge thereof as indicated in Fig. 1. The strap |20 extends outwardly and then upwardly from its pivot point |22 and its upper end is bent outwardly as at |24 so as to overlie the upper edge of the forward wall |2 of the tub |0. A circular closure member |26 is supported by posts 28 from the strap |20 in a position to close the open end of the cylinder 50. The size of the closure |26 and the length of the posts |28 are preferably such that the closure |26 is positioned with its periphery in relatively close but spaced relation with respect to the inner margins of the end wall 54 of the cylinder 50,l so as toV provide an effective closure for such open end of the washing cylinder but without setting up any rubbing friction. A handle |30 is preferably provided on the strap |20 to facilitate its manipulation with the cover |26.

It will be observed that because of the relation of the strap |20 with respect to the guard |00 and front wall I2 of the tub |0 it is necessary for the strap |20 and closure |26 to be in their normal operative positions before the washing cylinder 50 is placed in its normal washing position. When it is desired to introduce or remove clothes from the open end of the washing cylinder 50, the latter must be raised sufiiciently to permit the strap |20 and its closure member |26 to be swung outwardly away from the open end of the washing cylinder 50. It might be noted at this point that the cover ||2 for the guard |00 may be lifted away from the guard |00 while the washing cylinder 50 is in its horizontal position. this permitting the introduction of fresh water or the like into the tub |0 without necessitating moving the washing cylinder 50 to its vertical position.

It will be appreciated from the above descrip tion that with the exception of the various brackets, speed reducing mechanism, driving motor, etc., the construction of the washer of the present invention is such as to permit it to be fabricated substantially entirely from sheet metal, thus enabling it to be built at a minimum of cost. It will also be appreciated that the construction is unusually convenient for a housewife inasmuch as the clothes may be washed and wrung without Anecessitating their removal from the washing cylinder 50 and that because of the relative positioning of the driving and reduction mechanism with respect to the pivotal axis of the unit of which these elements are a part. the weight of the washing cylinder 50 and its contents is suiiiciently counterbalanced to permit the washing cyhnder to be swung from horizontal to vertical position and from vertical to horizontal position with a. minimum of effort. An additional feature is that because of the guard |00. the wash water between the guard |00 and the bottom of the tub I0 will be in a more or less quiescent state and will serve to trap dirt. lint and other materials washed out of the clothes and prevent their ready return to the bulk of the wash water between the guard |00 and the washing cylinder 50 and in the washing cylinder 50. At the same time the wash water in the tub is capable of freely flowlng through the ends of the guard |00 so as to obtain a desired circulation of the water in the washer. y
