DISH-WASHING MACHINE.
Application filed To all whom it may concern:
Be it known that I, EVEN citizen of the United States,
J. Roman, a
is a specificatlon.
This invention relates to certain new and useful improvements in machines particularly adapted for cleansing, washing or r1ns ing objects, such as dishes by spraymg a suitable liquid medium thereover, and has for its object to provide a machine for the purpose which will be efficient anl satisfactory and in which the medium employed, such as water will be thrown with force and continually from all directions upon and over the dishes in the machine. In accomplishing this I provide a washing tank and reticulate receptacle for the dishes removably positioned in the washing tank, together with means for rotating a body of water in the g said water to move upward and radially inward in a multiplicity of streams or sheets upon and around the dishes in the receptacle.
The full objects andadvantages of my invention will appear in connection with the detailed description thereof and are particularly pointed out in the claims.
In the drawings, illustrating the application of my invention in one form,
Figure 1 is a side elevation of an apparatus embodying my operation showing the platform cover extended. Fig. 2 is a plan view of the parts shown in Fig. 1, the dish receptacle being in position in the tank. Fig. 3 is a section on on line 33 of Fig. 2. Fig. 4 is a sectional plan of the tank only showing diagrammatically the manner in which the water is thrown over and around the dishes.
Any kind of a frame may be employed to support my mechanism, such, for example, as a series of posts 10 and tie pieces 11, a top 12 being ri idly secured to the tops of the posts 10. he top 12has the major portion thereof out out in a circular opening through which extend the walls of a tank 13, said tank bein g preferably cylindrical in. cross sectionhe top 12 has a metal cover 14 which may be otherwise to the top peripheral margin of the tank 13. A plurality of angle pieces 15 Specification of Letters Patent.
October 22, 1914, Serial No. 867,952. Renewed February 18, me.
residing at 'Minneapolis, in the county of Hennepm and an enlarged scale taken secured by solder or Patented ug. 3, 1920.
Serial No. 79,197.
are secured vertically to the inner walls of the tank 13, portions of said angle pieces extending inwardly radially and providing a plurality "of abutments breaking the continuity of the cylindrical surface of the interior of the tank. A peripheral flange ring 16 is secured to the inside of the tank 13 and upon the tops of the angle pieces 15. It is to be noted that the angle pieces 15 do 'not extend to the bottom of the tank 13 but are spaced at their lower ends from said bottom a suitable distance, as clearly indicated in Fig. 3.
A reticulate basket 17 is formed, preferably of wire netting material, havin an exceedingly large mesh and is secure at the top by a ring 18 provided with a peripheral flange 19. Handles 20 secured to the inside of ring 19 provide convenient means for handling the basket 17, which may be set within the tank 13 and held in proper position by engagement of the flange 19 of the basket with the flange 16 inside of the tank. When so held the bottom of the basket 17 will be spaced above the bottom of the tank to approximately the same extent as the ends of the radial strips'l5. The basket 17 is for the reception of'the dishes or other articles, which may be placed therein either when the basket has been removed and taken away from the machine, as to the diningroom-table, or when the basket is upon the shelf 25 formed by the cover of the machine, as indicated in Fig. 1. This cover is hinged at 21 to the top 12 and folding braces 22 are provided for holding the cover in extended position to form a shelf, as indicated in Fig. 1. The brace comprises the brace member 22 proper, hinged at 23 to a bracket 24 fast on the side of the uprights 10, said member 22 being pivotally connected to a link support 26, which, 'in turn, is pivoted to a link support 27 pivotally connected at 28 with the uprights 10.
The portion of the tank below the reticulate basket 17when the same is in'position in the machine isfor the reception of the washing water, which has a normal operative level, indicated by a dotted line at 29.
'Operative within this body of water beextends through the center of the tank 13, a stuffing nut 33 is threaded upon the lower extended end of the plug 32 and seals the bearin against leakage. The shaft 31 is journa ed at its lower end in a yoke 34 secured to the bottom of tank 13. The shaft 31 has thereon a bevel pinion 35 meshing with a bevel gear 36 on a crank-shaft 37, which may bemanually operated by hand crank 38. The shaft 31 also has thereon a pulley 39 by which shaft 31 may be driven through a belt 40 and pulley 41 from an electric motor 42 or from any other prime mover. Where the electric motor is employed, contact may be effected for driving the motor by means of a foot lever 43 on a shaft 44 journaled in uprights 10,-said foot lever being held in normal position to break the circuit by means of a spring 45 and operating through a contact piece 46 to close the circuit when the lever is depressed.
The operation of my machine will now be described. The dishes or other articles are placed in the basket 17, preferably being set so that the soiled surfaces, that is the insides of the various dishes, will be turned outwardly and in a position to drain, said soiled surfaces also should, as far as practicable, be slightly separated. The basket with the dishes therein is then placed in the tank 13 and the cover 25 is closed, a sufficient supply of hot soapy water being previously introduced within the tank 13. In this connection it may be noted that I provide a soap-container 47 upon an outside wall of the. tank 13, preferabl at an angle of the frame, where the form 0 is employed. This soap-container is provided with a removable cover 48 and communicates through a pipe 49 with the interior of tank 13, the pipe being controlled by a valve 50 which has its handle extending outside of the casing of the apparatus, as shown in Fig. 1. Liquid soap is employed in the container 47 which may be introduced. into tank 13 in the quantities desired by manipulation of valve 50. The basket having been placed in position as above indicated, and the cover closed, the paddles 30 are rotated at the desired speed either by the crank handle 38, the motor 42, or some other prime mover. The rotation of the paddle 30 will correspondingly rotate or' whirl the body of water in the bottom of the tank about a center corresponding to the center of shaft 31. Centrifugal force will tend to move said body of water outwardly, and, being mobile, to rise at the outer. periphery alon the inner walls of the tank cylinder 13. his raising action may also be slightly facilitated by turning the paddles 30 somewhat rearwardly from the direction of movement, as indicated in Fig. 4. The whirling and rising outer rim of water engages the bottoms of the ra ial pieces frame shown 15. The reaction of this engagement against said radial pieces at the junction thereof withthe cylinder Wall causes the water to spread along saidradial pieces and due to the abrupt surfaces with which the radial pieces are provided to moveabruptly and forcefully inwardly in a radial sheet the force being proportional to the rate of revolution of the paddle 30 and of the body of water at the bottom of the tank. Each of the radial pieces 15 has the effect of causing a sheet of water to move inwardly, so that as the paddles are turned a multiplicity of sheets of water are moving 'inwardly and upwardly, passing upon the surfaces of and through the dlshes in the basket 17 and returning therefrom to the body of water at the bottom of the tank. From this operation the water in the tank may be driven over and through the dishes and upon all the surfaces thereof many times in a few minutes of turning of the paddles 30. It is to be borne in mind that the soapy water is boiling hot and is thrown upon the dishes from every angle. The result of this operation is to thoroughly dissolve and remove all of the extraneous'matter clinging to the dishes so that after a comparatively brief turning of the paddles 30 there will be nothing left clinging to the dishes excepting soapy water. The Water in the tank 13 is then drawn off from the spigot 51 in the bottom thereof, which may be, if desired, permanentl connected with :the houseplumbing. hen clean hot water, preferably at boiling temperature, is added to the tank and the paddles 30 rotate again which thoroughly rinses the dishes. This water can be drawn off and the cover removed and the dishes in the basket 17 will quickly steam dry from their own heat.
It will be apparent, therefore, that I provide a simple and eflicient washing" apparatus. When the dishes or other articles to be washed are so arranged that the surfaces all drain, it will be apparent that the washing mixture, moving as it does radiall inward and upward, must contact with al 3 insures that all grease and dirt removed in the washing of the articles will also be rinsed out of tank 13, so that the machine itself is always clean and sanitary.
Iclaim: 1. A dishwashing machine comprising a tank, a series of bafile members secured to the walls of the tank and extending perpendicular to the bottom thereof throughout their length but having their lower ends spaced from the bottom of the tank, a reticnlate receptacle held inside of said bafiles within the tank and spaced from the bottom of the tank, and means for rotating a body of water in the space below the receptacle and the ends of said loafie members.
2. A dishwashing machine comprising a cylindrical tank, a plurality of vert1cal plates extending radially inwardly from the inner wall of the tank and having their lower ends spaced from the bottom of the tank, a reticnlate receptacle for dishes re-= rnovaloly held inside of said plates in the tank with its bottom in approximately the plane of the bottoms er the plates, and means for rotating a body of water at the bottom of the tank beneath said receptacle and plates.
3. A dishwashing machine comprising a cylindrical tank a plurality of plates e the tank with its bottom tending radially inwardly from the inner wall of the tank and having their lower ends spaced from the bottom of the tank, a reticulate receptacle for dishes removably held in in approximately the plane of the loottoms of the plates a double-bladed paddle journaled at the center of the tank and having the blades extended beneath the receptacle and the plates close to the inner wall-of the tank, and means for rotating the paddle.
In testimony whereof I allix my signature in presence of two witnesses EVEN J, ROHNE,
