My invention relates primarily to dishwashing machines, and particularly todishwashingma-v chines of the type designed for domestic use,
although many features of the same are equally 5 applicable to clothes-washing and other hydraulic machines. The main objects of the invention are the provision of new and improved mechanism for controlling, transferring and directing the liquid, and for producing the necessary mechanical movements employed in this type of machine; the provision of a new and improved mounting vand disposition of pump and motor; the provision of operating-mechanism constructed as a unit and attachable and detachable as a whole to the remainder of the mechanism; the provision of a new arrangement of motor pump and driving-mechanismitke provision of new and improved arrangements for evacuating and draining the machine; while further objects and advantages of the inventionwill become apparent as the description proceeds. In the drawings accompanying this specification and forming a part of this application I have shown, for purposes of il1ustration, one form which my invention may assume. In these drawings: v

The embodiment of my invention herein shown comprises a tub or leasing 11 mounted in a carriage 12 comprising four legs 13,. toA which the Figure 2 is a perspective view of the basket employed with this embodiment of my invention Figure 6 is a longitudinal vertical sectionall Figure 8 is an enlarged sectional view showing provided to facilitate movement of the dishwashing machine from place to place.
In the embodiment of my invention herein shown the tub 11 comprises a sheet metal section 17 provided with upwardly and outwardly eX- 30 tending portions 18 forminggfthe bottom Vof the tub 11, and with vertical portions 19 risingl from the upper edges of the bottom forming portions 18 and forming the sides of the tub 11; sheet metal end members 20 closing the ends ofthe 65 trough so. formed; extensions of the side walls 19 and end walls 20 bent to form an inner flange' 21 adapted to support a cover 22 closing the topof the tub 11, and an outer ilange 23 adapted to support an annular top section 24 resting 70 directly on the outer ange 23, provided with a depending rim 25 arranged to be inserted between the vertical portion of the outer ilange 23 andthe depending flange 26 of the cover 22, and
carrying along its lateral edges top extensions 27 75l provided for supporting the articles to be washed and formed from a plurality of wire members 33 carried by two hubs 34 positionedat the two ends of the basket 32 and arranged to support vthe basket 32 from the end walls 20 of the tub 11 90 by engagement one with an extension 35 pro jecting from a stud 36 fixed to one end wall 20 of the tub 11 and elongated to cooperate with the elongated slot 37 of that hub 34 to prevent rotation 'of the basket' 32, and the other by en- 5 .gagement with an extension 38 projectingl from the hollow member 39 here shown as rotatably' mounted in a bearing 40 carried by the other end wall 20 of the tubll.
Also mounted within the tub 11 is an emitting means provided for discharging washingctluid upon. the articles to be washed and herein shown as comprising a pipe 44 carried by the hollow member 39 and swinging in the space between the basket and the end wall of the casing, a also comprising longitudianl perforated pipes 41 projecting from and--carried by the pipe 44 and movable in an orbit about the basket. The
bore' 45 of'the member 39.communicates'with 1lo Mounted within the tub 11 is a basket 32 85 tom 50, secured together at their rear ends by a cross member 51, and secured `together at their forward ends by a cross member 52 normally closing an aperture 53 through which the screen unit 48 may be withdrawn, and removably held in position closing the opening 53 by means of a latch 54 engaging a Suitable cam surface 55 on the screen 'handle 56; and the means for removing fluid from the tub 11 comprises an outlet duct 61 communicating with a sump or trough 57 with which the -base of the tub 11 is formed-below the screen unit 48 and therefore in position to receive the fluid \of the tub 1l only after the solid matter has been removed therefrom-by the screen unit .48. 'I'his screen is substantially horizontal and ofconsiderable area to prevent clogging, the screen-bottom being spaced suflciently-below the tops of the side members to afford-room for the collection of Waste, and the sides of the tub have sloping ledges which overlap the sides of the screen so as to deliver all such waste material onto the screen.
My invention'also provides means for moving the tubes 41 orbitally about the basket 32 to cause the washing fluid to impinge on the dishes from all directions, and means for pumping the washing fluid from the outlet duct -61 either back through the tubes 4l or out through a discharge duct 58. In the embodiment of my invention herein shown the pump 59 is of the centrifugal type having its inlet 60 connected by means of a duct 61 to the sump 57 of the tub 11, operated by means of a vertical shaft 62 directly connected vto the armature shaft 63 of an electric motor 64, and having its outlet 65 connected by means of a duct 66 to a valve chamber 67 opening on one side through a port 91 into thedischarge duct 58, and opening on the other side through a port 92 into a pressure duct 68 leading to the chamber 46 of the' bearing 40 to thus connect the outlet 65 of the pump 59 through the aperture 45 of the movable` member 39 to the cross duct 44 andthe tubes 41. The ow of the uid from the valvechamber 67 through the ports 91 and 92 is controlled by a valve disc 69 operable from a handle 70 through a stem 71 into a lower position closing the port 91 and connecting the outlet 65 of the pump 59 to the pressure duct 68, or an upper pvsition closing the port 92 and connecting the outlet 65 to the discharge duct 58, or to an intermediate position opening both ports' 91 and 92 to drain everything into the discharge duct 58. Rotation of the tubes is effected by a gear 72 operated by a worm 73 carried by the pump shaft 62 and operating a shaft 74 extending into the tub 11 and carrying on its inner end a `pinion 75 meshing with a gear 76 secured to the rotating member 39 and therefore effective to rotate said member 39 and cross duct 44, and with them, to rotate the tubes 41 about the basket 32.
The pump in'let 60 isextended vertically upward in the form of a hollow sleeve which -rises suiciently above water level to avoid the necessity for any packing gland. A The upper end of this sleeve is enlarged at one side to form a casing 96 for the gear 72` and its friction gland, the face of said casing being .closed by a movable cover. 97. This brings the casing 96.c1osely adjacent to the bearing 40 and I preferably, therefore, cast the two integral one with the other; indeed Il find it preferable to provide a single unitary frame for the entire operating mechanism, this frame in the present embodiment comprising two upright hollow members 68 and 95, the bearing 40 and gear case 96, the pump chamber and its outlet pipe, 66, the valve chamber 67 and the motor seat 98. Ob-
viously this frame could be made in a great many forms but inthe present embodiment it defines substantially an open rectangle surrounding the garbage drawer cross member 52 and is secured in place by the bolts 77, 78, and 79, the last named serving to connect the pump inlet 60 to the duct 61. The trunnion 39 is inserted into the bearing 40 after Athe latter has been secured to the tub wall and is secured in position by means of a bolt 80 extending through the rotatable member 39 into a.l cooperatingly screw-threaded aperture 81 in the remote end of the bearing 40,; and I drive the shaft 74 rotating the tubes 41 through an impositive connection herein shown as comprising a fric- 10 tion member 82 splined to the shaft 74 and urged into frictional engagement with the gear 72 bymeans of a spring 83 compressed between the friction member 82 and an adjustable abutment 84 carried by the end of the shaft 74.
While thedischarge duct employed with the embodiment of my invention herein shown may be of any suitable construction I prefer to provide this discharge duct with a U-shaped rigid terminal 85 adapted to hook over the edge of a sink or tub, or over the rim of a hollow inlet member- 86 communicating with the interioriof the tub l1 to return -into the tub 11 any fluid inadvertently flowing into the` discharge duct 58, and to form this terminal 85 to hook over at any angle by connecting this terminal 85 to the remainder of the discharge duct 58- by means of a swivel connection more particularly shown in figure 8 and comprising a sleeve J .87 screw-threadedly united to a plug 88 unitary with the body of the discharge duct 58, and swivelly connected to the terminal 85 by means lof an inwardly extending flange 89 overlying an outwardlyextending flange 90 carried by the terminal 85. .A
The operation of the motor 64 may be controlled by a suitable electric switch 94.
From the foregoing" description it will be 0bvious to those skilled in the art that I have provided a dishwashing machine wherein washing and rinsing operations can be performed with a minimum amount of fluid, wherein the table refuse mechanism is driven by a single motor, and carried -in ,a single frame'readily removable from .the tub as a unit, and wherein no packing is required about the pump operating shaft, or about the driving shaft which extends through the liquid.
At. the same time it will also be obvious to those skilled, in'` the art that the embodiment of myv invention herein shown and described comprises advantages other than'those specifically pointed out or suggested herein, and also that the particular embodiment of my invention herein shown and described may be variously changed and modified without departing from the spirit of my invention or sacrificing the advantages thereof, and it willtherefore be understood that the disclosure herein is illustrative only, land ythat my invention is not limited thereto.
