UNITED STATES CHARLES I'. DOIBLE, OF WOLLASTON, MASSACHUSETTS.
DISHWASHING MACHINE.
Application filed Jul io,
To all whom it mag/ concern:
Be it known that I, CHARLES F. Donna, a citizen of the United States, residing at Wollaston, county of Norfolk, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Dish: washing Machines, of which the following is a specification.
This invention relates to dish washmg machine, and particularly to the water action thereof.
The object of 'my invention, generall stated, is to provide for a more thoroug and eflicient cleansing of the dishes than has heretofore been attained.
To this end, the dishes are supported in the u per portion of the tank and the washing fi uid is simultaneously projected upwardly past the dishes and downwardly thereupon in a revolving sheet whereby to uniformly cover and thoroughly cleanse both faces of the dishes.-
, In the embodiment of my invention illustrated in the present application, the upward and downward pro ection of the water over the dishes is accomplished by a rotary propeller and a rotary pump, respectively, which are both mounted within the tank for rotation about a common axis and in addition revolve as a unit over the tank bottom about an axis transverse to their axis of rotation whereby to project the water as a revolving sheet in a multitude of directions over the dishes. In this application the propeller and pum are simultaneously rotated and revolved y a motor located exteriorly of the tank.
In addition to its waterdistributive action during the washing operation, the rotary pump may be utilized to fill or empty the tank where no direct pipe conmotion to the water suppl and drain is available, thus reducing the installation cost of the machine by obviating the necessity for any expensive modification of existing plumbing facilities.
The construction and operation of my invention are described and shown in the accompanying ispecification and drawings and the characteristic features of novelty are particularly ointed out in the appended claims. Througliout the specification, and drawin s like reference characters are correspon ingly applied, and in the drawin Fig. 1 is a vertical longitudinal section 1922. Serial ire. 514,059.
delivery end of the discharge pipe from the rotary pump particularly showing the nozzle construction, and
Fig. 5 is a detail view at the delivery end of said pipe, particularly showing the swivel connection for the filling and draining hose. I I have indioated at 1 a base ring to which 18 connected a plurality of suitably braced legs 2 for supporting the tank 3 of the washer-at a proper elevation. Suspended within the tank above the water level and in super osed relation to ,each other are, respective y, a dish,rack 4,
a silver tray 5 and a tumbler basket 6.
Mounted exteriorly of the tank, preferably therebeneath, is an electric motor 7. The motor shaft 8 is separably connected by a universal joint 9 with a vertically disposed drive shaft 10. The shaft 10 extends through the tank bottom substantially axially thereof, the opening in the tank bottom being closed by a stuffing box 11, and within the tank is journaled in a bearing 12 resting upon the tank bottom.
Revoluble upon the bearing 12 as an axis is a rotor casting 12' comprising spaced bearing uprights 16 at one side of the axis of revolution and a pump-casing 19' at the other side of said axis. 4
J ournaled in said bearings 16 and in the pump casing is a horizontal shaft 13 which is rotated from the drive shaft 10 by intermeshing gears 14; and 15, respectively, on said shafts.
Fast on the shaft 13 between the bearings 16 are arms 18 carrying a pair of oppositely disposed water projecting blades or propellers 17 for projecting the water upwardly over the dishes in a revolving stream under the combined rotation and revolution of the shaft 13. The blades 17 are partially incurved deflector or apron 16 which extends in close proximity to said blades throughout substantially the lower quadrant of their movement and like the screen follows the revolution of the blades over the tank bottom. See Fig. 2. The bearings 16 are preferably connected by a pluralit of spaced longitudinally extendlng tie ro s 16'.
Fast on the shaft 13 within the pump casing 19' at the opposite side of the axis of revolution of said shaft is a bladed rotary piston 19. Water is admitted into the easing to said piston through an inlet pipe 20, the intake end of which is rovided with a removable screen 20, and-1s projected upwardly by said piston through the outlet 20 of the casing into a delivery pipe 20 which is preferably bent to pass upwardly through the superposed dish rack, silver tray and tumbler basket in substantially the longitudinal axis of the tank.
Fitted to the upperend of said pipe 20 is a discharge nozzle 21 which is provided with an elongated discharge port 22 adapted to project the water in a revolving sheet over the dishes as the casting 12' is revolved about a vertical axis over the tank bottom. (See Fig. 2.)
By in invention the water projecting blades 1 and the rotary pump piston 19 are simultaneously rotated about a horizontal axis (the shaft 13) and revolved as a unit about a vertical axis (the shaft 10) so i as to project the water both upwardly and downwardly and at multitudinous angles over the dishes.
The nozzle 21 is made detachable so that it may be removed and a hose 23 connected with the pipe 20 to permit the tank to be filled through the pump where there is no direct pipe connection to the water supply.
In order to adapt the pump for emptying the tank under similar conditions, I provide a swivel connection 24 (Fig. 5) which may be substituted for the nozzle 21 to which the hose 23 may be attached. With such connection when the pump is started to empty the tank, the swivel connection 24 permits the hose 23 to remain stationarv 'as the pump revolves over the tank bottom.
Preferably the hose 23 is led into the tank through a hole 25 (Fig. 1) in the hinged tank cover 26, said hole being normally closed by any suitable threaded cap (not shown).
Let into the bottom of a tank is a drain fitting 27 with which a sewer connection may be made if desired, and the tank will, of course, also have a filling connection.
As will be evident, the separable connection at Qpermits the shafts 8 and 10 to be disconnected and the rotor, propeller and pump to be bodily removed from the tank for purposes of cleaning or repair.
Various modifications in the construction and operation of my device may obviously be resorted to without departing from the spirit of my invention if within the limits of the appended claims.
What I therefore claim and desire to secure by Letters Patent is:
1. In a dish washing machine, a tank, means for supporting dishes therein, a rotary propeller and a rotarypump mounted within said tank, for simultaneous rotation about a common horizontal axis, and cffective to project water upwardly past and past and downwardly upon the dishes and means for revolving said propeller and pump about the vertical axis of the tank, to project the water against the dishes in a revolving sheet.
3. In a washing machine, a tank, means for supporting dishes therein, a rotor shaft journaled in said tank, a bladed propeller and a rotary pump mounted on said shaft at opposite sides of the vertical axis of the tank for projecting the water upwardly past and downwardly upon the dishes, and means whereby said shaft is simultaneously rotated and revolved about axes of rotation and revolution in relative angular disposition to each other to project the water against the dishes in a revolving sheet.
4. In a washin machine, a tank, means for supporting dis es therein, a rotor within said tank, a bladed propeller and a rotary pump carried by said rotor for projecting water upwardly past and downwardly upon the dishes, means for simultaneously rotating and revolving said propeller and pump about axes of rotation and revolution at right angles to each other to project the water against the dishes in a revolving sheet.
5. In a washin machine, a tank, means for supporting dis es therein, a rotor within said tank, a bladed ropellerand ajrotary pump carried by sald rotor for projecting water upwardly past and downwardly upon the dishes in a revolving sheet, and a motor mounted exteriorly of the tank for simultaneously rotating and revolving said propeller and pump about axes of rotation and revolution at right angles to each other.
6. In a washing machine, a tank, means for supporting dishes therein, a rotary pump within the tank having a discharge downwardly onto the dishes from a point above, and means for rotating and revolving said pump about axes of rotation and revolution in relative angular disposition t9 each other.
axis of the tank for projecting water upwardly past and downwardly upon the dishes in a revolving sheet, and a motor mounted exteriorly of the tank and operatively connected to said rotor for simultaneously rotating and revolving said shaft about axes of rotation and revolution at right angles to each other, said pump having a delivery pipe extending along the vertical axis of the tank and terminating in a downwardly directed discharge.
In testimony whereof I afiix my signature in presence of two Witnesses.
