WASHING AND DRYING MACHINE.

Application filed 0ctober 2 1, 1920. Serial No. 418,570.

This invention relates to combination washing and wringing machines, its general Object being to provide a machine in which the clothes may be washed and wrung by centrifugal force without removing the clothes from the container, by swinging the container to different positions.

Another object is to provide a machine which has a stationary outer casing which encloses the container in both its washing and wringing positions, thus preventing the 'splashing of water outside the machine at i all .times. 2

Another object is topro'vide a mechanism for swinging and driving the container which is disposed entirely on the under side of the stationary casing so that it will not interfere with the operator.

Other objects are: To provide a common 7 means for. supporting and rotating the container when 1n the wringing position; to provide a common means for operating the container in both its washing and wringing position; to provide bevel geanfor operating the container in'both washing and wringing positions and whic remains meshed with its driving gear when the container is swung to different positions; to provide a container with telescopic sections so that more space may be provided for the clothes during the washing operation. 2

Other objects and those relating to economies of manufacture and simplicity and lightness of construction will appear later as I proceed with a detailed description '0 that particular embodiment of my invention which for the purposes of illustration I have shown in the accompanying drawings, in'whichv Figure I is a vertical section through the center of the clothes container when the same is in the wringing position. Figure II is a vertical section on line 2-2 of Figure I but showing the container in the washing position. V

1 represents the stationary outer casing of the machine which is constructed to comin FiguresI' and II. The lower portion 2 of the casing is filled with water to the desired level dependent upon the amount of clothes to be washed and preferably has a drain cock at its lowest point for draining purposes. The ent re outer casing is preferably made of sheet metal and rigidly supported upon a frame structure 3. The

clothes container 4 is cylindrical in shape and is made of some pervious material such as perforated sheetmetal and is supported at itscenter when in the wringingposition by the'vertica-l shaft 5. The shaft 5 is supported at its lower end by a collar 6 bearing upon the hollow member 7 which is pivotally supported upon the central part 9 ofthe stationary outer casing. One end of hollow member 7 has an internally threaded member 10 welded to it as shown in Figure VI, the outer cylindrical surface of member 10 having a bearing 11 on the part 9. The other end of member. 7 is supported by the shaft 8 which has a bearing 12 on the part 9. Fitting within member 10, is the exf ternally threaded nut 13 with wide pitched threads fitting those of the member 10.-

Shaft 8 runs through the center of nut 13 and has a collar 14 fitting within a groove in nut 13 so that shaft 8 partakes of any lateral movement of nut 13. The bevel gear- 15 is splined upon shaft8 to allowlateralmovement of the shaft, and intermeshes with bevel gear .16 which is keyed upon the shaft 5. Gear 16 also has a bearing upon member 7 to hold shaft 5 in place during the washing operation:

During the wrmgmgoperation shaft 8 is driven through the train of gears 17, 18, 19,

and 20 as clearly shown in FigureI. Shaft 21 to which gear 20 is keyed is driven by the electric motor 22 through the clutch 23. The hollow member 7 is held in its wringing position by the catch 24 extending through the stationary part 9 into a hole 80 fork 27 which is also rigidly attached to member 25,. Thus it is seen that clutch 23 is disengaged whenever the catch 24 is withdrawn, so that it will be impossible to tip' the clothes container 4 from one position to the other while it is connected to the power source 22. However, by withdrawing handle 26 only a short distance clutch 23 may be disengaged without releasing the catch 24.

In starting the washing operationthema-' chine parts will be in the position shown in Figure I. The cover 30 is removed and the articles to be washed put into the container 4. The cooperating and telescoping closure 31 of the container is now inserted to its position. This member 31 forms an extension to the cylindrical part of the container and also provides one end portion to hold the clothes from falling out during the washing operation. The member 3.1 is rigidly attached to the container 4 by the extensions 32 ,(see Figure III) which fit snu ly into recesses 33 (see Figure I) provi ed therefor. The inner surface of both the con tainer and cooperating closure member are provided with longitudinally extending vanes or lifters 34, which serve to carry up the clothes from the bottom and drop them again through the water and suds. The recesses 33 are preferably formed where the vanes 34 are attached to the cylindrical portion, as shown in Figures I and H. The

- portion 31 being firmly in position, catch 24 is withdrawn by handle 26 and the clothes container tipped over to the washing position. A trunnion 35 rigidly secured to portion 31 falls into the stationary bearing 36 and thus the outer end of thecontainer is supported during the washing operation. The inner end is supported by its attachment to shaft 5 in such a manner as to allow for a slight disalignment in order to obtain exact balance of the cage when rotated at high speed for dr ing. This is accomplished by providing a gall and socket connection between shaft 5 and the container. Shaft 5 has the ball 40 and the center piece 41 of the contamer 4 has the socket 42 which has a slightly greater radius'than ball 40 and therefore allows a slight rocking of the container upon the ball 40. The projections 43 on the ball 40 however, fit into correspond- 7 ing grooves in the socket 42 which are deep enough to permit the above described rockmg motlon but yet not disengage the clutch connection. The ball 40 is held up into the socket by the three pivoted catches 44 (see Figures I and IV). These pivoted catches drop down by gravity when the cap 45 is withdrawn and thus allow the ball to be inserted. The cap 45 is then screwed on and presses against one arm of each of the pivoted catches '44, thus holding them up against the conical bottom of ball 44. The above described structure permits a slight rocking motion of the clothes containerbut gives a rotary driving connection at all times. lVhen the container is tipped over to the washing position the hollow member 7 together with member 10 is revolved about 90 degrees. The internal threads ofmember 10 engaging the external threads of 'nut 13 cause the nut 13 to be shifted bodily to the right as viewed in Figure I. On account of the collar 14 the entire shaft 8 is shifted to the right also, thus bringing clutch into engagement, and causing driving connection between shaft 8 and the stub shaft 60 of the reversing mechanism 51. The nut 13 is prevented from rotating by the yoke lever 52 which engages two diametrically opposed pins 53 on the nut 13. The yoke lever 52 is opposite end is forked and engages a collar 55 keyed to the shaft 56. Therefore when the nut 13 shifted to the right the lever 52 shifts the shaft 56 to the left together with the gears 18, 19, and 57 keyed thereto. This motion will disengage gear 18, shift gear'19 along the long gear 20 without disengagement, and engage gear 57 with the gear 58, which isjkeyed to the driving shaft 59 of the reversing mechanism 51. of this reversing mechanism are not shown as the same'are well known to those skilled in the mechanical arts and it is not thought necessary to illustrate any particular type here. Its operation is such that when shaft 59 is rotated continuously in one direction the shaft 60 is first rotated several revolu- The details pivotedon the stationary pin 54 and its tions in one direction and then the same tric connections for-the motor: being made, the container will now be rotated several revolutions in one direction and then several revolutions in the other,'this operation being continued as long as may be required to clean the clothes. To stop this operation the handle 26 is pulled out, thus disengaging clutch 23. The container may now be turned up to the wringing position. Toaid in thus raising the contalner a small Windlass 61 operated by the hand crank 62 may be provided, the cable 63 passing over a guide pulley 64 and hooked or fastened'onto some portion of the container, such as one of the corresponds to the washing position. Elecmoved and the operationrepeated with another batch of clothes.

By my invention it is not necessary to drain off the water in order to wring the clothes with the same container in which they were washed, Moreover the entire operating mechanism is simpler and lighter than those heretofore used.
