The present invention relates to certain new and useful improvements in washing machines of that general type in which a clothes or fabric receiving drum is mounted so that it can be either brought into an upright position and rapidly rotated about a vertical axis to expel the moisture from the contents of the drum by centrifugal force, or tilted into a different position and moved 1 at a slower rate of speed for subjecting the contents of the drum to the action of a cleansing fluid or the like. 2 3 I Among the objects of the invention are to provide a washing machine of this charac ter which is so constructed that the clothes or fabric containing drum can be readily moved into the proper position for washing or drying and positively connected to the drive shaft in either positlon. 4 The invention further contemplates a washing machine of this character in which the clothes or fabrics to be treated can be successively subjected to the action of several fluids without bein removed from the drum. :5 For instance, clot es being washed can be washed and rinsed or washed, rinsed and blued without being handled or removed from thedrum.

The invention also contemplates a mounting for the drum in which the drum has a limited universal movement about its connection with the vertical drive shaft when it is in an upright position. This is adv'an-- tageous for the reason that it enables the operator to distribute the clothes evenly in the drum when placing them therein and also for the reason that when the drum is rapidly rotated the center of gravity of the drum and load therein can be brought over the axis of the verticaP shaft, thereby and has Serial No. 9 ,622.

For a full understanding of the invention reference is to be had to the following description and accompanying drawings, in which Figure 1 is a top plan view of a washing machine which is constructed in accordance with the invention, the clothes receiving drum being shown by full lines in an upright position and by dotted lines in a tilted position.

Corresponding and like parts are referred" to in the following description and indicated onall' of the views of the drawings by like" IGIEGI'GIICQ characters.

Referring to the drawings, the numeral '1 designates a tub which may be of any desired size and shape, although in the present instance it is circular in cross section. This tub into two separate compartments A and B. These compartments may contain dif-- ferent fluids with which it is desir d to treat the fabrics or clothes, and for was in P k poses one of the compartments woul orditures, since with a thin metal partition the upwardly at 6 to provide a conical thesaid partition and at the a pocket. The lower end of the heat would be quickly transferred from the hot fluid in one compartment to thecooler fluid in the other compartment.

The clothes receiving drum is circular in cross section and has the usual perforated walls. The bottom of the drum is pressed A drum shaft 7 is arranged at the axis of the drum. and projects downwardly within the conical pocket in the bottom of the drum. A transverse'partition 8extends across the pocket at an intermediate'point in the length thereof and the shaft 7 is firmly anchoredin x of the rum shaft terminates in a polygonal stud 9 which is adapted to engage either-a socket 10 at the upper end of a vertical drive shaftll, or one of the sockets 12 at the outer ends of the laterally inclined shafts 13, depending upon the position in which it is desired to support the drum. 1

The vertical drive shaft 11- is journaled within a'tubular-bearing 14 which extends upwardly at the center of the tub and is rigid v with the transverse partition 4. Power may be applied to the driveshaft in any suitable manner, and for this purpose the lower end of the drive shaft is shown as extending into the gear compartment 3 aDdPIOVIdGd wlth a pinion 15- meshing with a gear wheel'16,

the shaft 17 of the said gear wheel 16 extending downwardly'below the compartment 3 and be connected by a worm-gearing 18 with th d haft of an electric motor 19. This is merely a conventional way of driving the shaft and any other suitable mechanism may be employed for that purpose.

The upper end of the tubular bearing 14 terminates in an enlarged head 20 having which receive the inner ends of the lateral' shafts 13. The sockets 12 at the outer;

' ends of the lateral shafts are shown as journaled within bearings 21 formed in connection with a substantially semi-spherical gear casing 22. The lower edge of this gear casing 22 is flanged andsuitably connected to a plate 23 which is mounted upon the tubular hearing. The lateral-shafts 13 are provided with comparatively large gear wheels 24 which mesh with a smaller gear wheel 25,- WherebythelateraI shafts are driven from the vertical shaft but rotated at a slower rate of speed. The sockets 12 of the lateral shafts have the mouths thereof substantially flush with the exterior of the gear casing member 22 so that the polygonal stud!) of the drum pocket.

stud 9 of the drum shaft shaft can bereadily inserted in either of the sockets. A

The drum shaft 7 is provided at a point above the polygonal stud 9 with a circular plate 26 which is rigidly applied thereto, and

when the polygonal stud of the drum shaft 1s m engagement with the socket 10 of thevertical shaft this plate 26 is slightly spaced socket 10, although it fits the lateral sockets 12 with a fair degree of accuracy.

When it is desired to spin the drum about a.vert1cal axis for the purpose of centrifugally drying the content thereof, the polygonal stud of the drm shaft is placed in engagement with the upright socket 10 of the verticalshaft, whereby the drum shaft is supported in substantial alignment with the vertical shaft. The flange-or plate26 of the drum shaft is then just slightly spacedfrom the yieldable flange 27 of-the socket, and owing to the looseness of the stud within the socket the drum has a limited universal tilting movement about the joint. When the clothes are being placed in the drum thelatter will bear down on one side or the other according to the disposition of the weight of the clothes and the operatoris thus enabled to obtain an approximately uniform di'stribution of the clothes. After the clothes have been placed in the drum and the latter is caused to be spun at a high rate of speed the loose joint between the drum shaft and the drive shaft permits the drum to assume the proper position to bring the center of gravity of the drum and load on the axis of the vertical shaft so that the drum can spin without excessive 'vibrationor undue strain upon the shaft and bearing. It will be observed that the lower end of the drum shaft 7 terminates within theconical pocket and above the bottom of the, drum, so that the point of. support is as high withimthe drum as possible,

thereby. obtaining greater steadiness in the mounting of the drum.

When it is desired to subject the contents of the drum to the action of the fluid in one of the compartments of the tub, the drum is bodily lifted until the lower end of the drum shaft is disengaged from the upright socket 10, afterwhich thedrum is tilted downwardly intoan angular position until a portion of the periphery thereof is submerged in the fluid of the compartment and the poly onal can be move into the socket 12 of the corresponding lateral shaft 13. V In order-to facilitate the shifting of the position of the drum a guide plate is arranged over the top of the gear casing 22.

\ The guide plate is substantially semispheri cal in shape and the peripheral edges thereof are provided with a flange which is secured to the gear casing. The top of the guide plate is formed with a clearance openthe same. Guide. slots 32 are formed in the guide plate and extend radially from the clearance opening 31 toward the sockets 12 of the lateral shafts. An outwardly projecting rest 33 is provided at the end of. each of the guide slots 32. When thelower-end of the drum shaft 7 is lifted out of the socket 10 of the vertical shaft it .can be moved laterally into one of the slots 32 of the guide plate, the flange or plate 26 of the drum shaft engaging the top of the guide plate and sliding over the same. The drum can then be moved in the direction of the guide slot-32 until, the flange 26 of the drum shaft en'- gages the rest 33 at the end of the guide slot. The drum may be handled or tilted so that the drum shaft is then inclined with respect to the lateral shaft, and with the flange 26 of the drum shaft supported by the rest 33 the polygonal head at the end of the drum shaft can be brought into registry with the socket 12 of the lateral shaft,- whereupon the drum can be slightly lifted to bring the drum shaft into alignment with the lateral shaft and given a shove to move the polygonal head into the socket. In order to permit this action clearance openings 34 are provided at the ends of the guide slots, said clearance openings being sufliciently large to admit of the free passage of theflange 26 of the drum shaft therethrough. It will also be observed that the formation of the guide. plate is such 1 that the marginal portions. thereof are brought closer to the top of the gear casing than the central portion thereof. Where the tub is formed with two compartments, such as that shown by Figures '1 and 2, the guide plate will be provided with two of the guide slots 32, as shown by Figure 6, there being one ofthe guide slots for each of the compartments. Should the tub be subdivided into three compartments the guide plate would be provided with three of the guide slots 32,as shown by Figure 7, there being one of the guide slots for each of the tub compartments.

A drain plate 35 is provided for covering all of the tub compartments with the exception of" the one that is in use.- The drain plate is pivotally mounted upon the upper end of the tubular bearing 14 and is provided with a handle 36 by means of which it can be swung around within the tub into the desired position. The drain plate is inclined downwardly toward the free edge thereof so trifugaldryer the fluid which is expelled thereby from the clothes will be drained back into the compartment from which it was taken. A

A modification isshown by Figure 8 in which the lateral shafts 13 are horizontally disposed instead of being arranged at an inclination to the horizontal as shown by Figures 2 and 3. The inner ends of the hori zontal shafts are journaled in the enlarged that when the drum is being used as a cen- I head 20 of the tubular bearing 14, the

outer ends of the horizontal shafts terminating in sockets whichare journaled in bearmgs 21 in the gear casing 22". The

horizontal shafts are provided with-gears 37 which mesh with a gear 38 on a tubular, upright shaft 39. The drum shaft 7 may extend entirely through the drum so that when the drum is moved downwardl to bring the drum shaft into horizontal position the outer end of the shaft will engage a seat 40 on the walls of the tub to assist in supporting the drum. The polygonal stud 9 at the end of the drum shaft 7 is adapted to be engaged with thesockets of the respective shafts, ust as in the previously described construction. The guide plate 29 which is arranged over the gear casing 22 operates exactly as previously described to assist in bringing the polygonal stud of the drumshaft into engagenient with the sockets 12 of the horizontal shafts. When the drum is swung upwardly with the drum shaft in a vertical position it can be spun rapidly to expel moisture from the contents thereof by centrifugal action, while when the drum is moved downwardly to bring the axis thereof into-a horizontal position the outer end of the drum shaft is supported by the seat 40 and the drum is rotated at a comparatively slow .1

speed. The change in the speed at which the drive shaft is driven may be caused auto-" stop member such as a pin 44. The spiral spring'normally tends to slide the pinion 42' upwardly into the full line position shown by Figure 8. Theupeprv end of the gear shifting rod 41 then projects into the base of the socket 10 so' that it will beengaged by the polygonal stud 9 of the drum shaft and pushed downwardly thereby if the drum is moved upwardly with the axis ahereof in a vertical position. When the. gear shifting rod is thuspushed downwar .y the pinion and is interposed between the pinion and a 42 is moved into the position indicated by dotted lines on Figure 8. When the pinion 42 is at the lower limit of its movement it engages a suitable gear member 45, while when it is at the upper limit of its movement it engages a gear member 46. These gear mem- "bers may be driven from any suitable source of power, and the'gear member 45 operates to revolve the'vertical shaft at ahigh rate .of speed, while the gear member 46 operates stud 9 is withdrawn from the socket 10 preparatory to swinging the drum downwardly.

1 The drum-is provided with a suitable cover 46 which fits in a suitable seat at the mouthof the drum. Anyi suitable means may be provided for securing the cover'in position, and in the present instance jthecover is shown as provided at one side. thereof with a tongue 47 which interlocks with a suitable opening at the mouth of'thedrum,

The triangular baflle plates and conical projection in the center of the drum thus cooperate with each other to cleansing of the bring about an effective clothes. In all forms of the inventionthe .drum is adapted to be detachably, connected with either a vertical shaft or a lateral shaft, being driven at a high rate of speed for centrifu- 'gally drying the contents thereof when it is connected to the vertical shaft, and being driven at a comparatively slow rate of speed 4 while connected to the lateral shaft. a por tion of the periphery-of the drum being submergedin a fluidsinione of the tub compart ments so that the contentsfof' the drum will be subjected to the action of .the said fluid whenthe drum is in the latter position.
