DISH-WASHING MACHINE.

,sp-puma@ med im 1o,

Be it known that I, ROBERT H. SUNKLE, a citizen ofl the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented new and useful Improvements in Dish-VVashing Machines, of. which the following is a specification.

The invention relates toan improvement in dish-washing machines wherein dishes or the like. are subjected'to a rapid movement in a body of water or other cleansing fluid.

The main object yof the resent invention .is the provision of means or subjecting the dishes to a rapid reciprocatory movement within a suitable vessel and adapting/said means for similar operation in connection with a rinsing-tank, whereby the dishes may be thoroughly cleansed and rinsed without handling.

A further object of the invention is to adapt the operatingmeans for travel from the cleansing-tank to the rinsing-tank and from the latter to a table or support upon which the dishes may be deposited for drainmg.

With these objects in View the invention consists in certain details of construction and combinations of parts which will first be described in the following specification and then pointed out in the claims.`

The preferred embodiment of details of the structure are clearly illustrated in the accompanying drawings in two sheets, in which- Figure 1 is a view in side elevation of a dish-washer constructed in accordance with my invention. Fig. 2 is a longitudinal section, partly in elevation, of the same, the operating mechanism being omitted. Fig. 3 is a top plan view, and FiU. v4 is an enlarged broken side elevation,`ilzfustrating particuarly the. operative mechanism. Fig. 5 is a bro en view in elevation, partly in section, showing the connection between the plunger and the basket-supporting arm.

v Referring to the drawings, wherein like parts are indicated by like reference-numerals throughout the several views, my improved dish-washing machine includes tanks 1. and 2 and a ta le 3 for receiving the cleansed dishes, all of which parts may be of any preferred size and are arranged in alinement longitudinally of the machine. The tanks 1 and 2 and the table 3 are sup orted5 in a framework including side bars an bars, said tanks and tab e being constructed practically of a single strip of .materiah Vas g Specication of Letters Patent.A

The upper ends of the tanks 1 and 2 are bent laterally to provide what are termed .dri tables"` 4 and 5 respectively, the surfaces o which tables are tinuation of the receiving-table. The driptables and receivingtable which are disposedin alinement longitudinally of the machine have an edge flange 6 projecting above the respective surfaces and a similar edge flange 9, transverse anges 7 and 8 dividing the respective tables, as clearly shown in Fig. 3. The flange 9 is arranged for service asa track for supporting the movable parts of the' machine, as will later appear.. -As thus described, each of the drip-tables and receivingtable is guarded by edge flanges on foui' sides, and the drip-.tables are respectively formed with centrally-disposed openings coincident with the open ends of the cleansing and rinsing tank. As said tables are practically square in plan, considerable surface is prorespective tanks and within the edge flanges,` `said surface servin to direct any water escaping from the tan sin the operation of the machine b'ack into its proper tank, as will be obvious. The fiange 9 provides the ,upper and will be hereinafter referred to as track 9. In connection with this track 9a lower track 10 is secured in vertical alinement the frame-bars.' he tracks extend longitudinally throughout the length of the machine and are designed to provide for the, movement of the operating mechanism hereinafter described.'

The operating mechanism comprises a carriage 11, preferably including three vertically arranged parallel bars 13, 14, and 15 and 'transverse bars 16 joining thevertical bars near their respective ends. The u per ends of each of the vertical bars is provi ed with a flanged wheel 17, designed to engage the upper track 9, while the lower ends of these bars are similarly provided with a lian ed wheel 18 to engage-the lower track 10.. T e wheels 17 and' 18 'are perferably positioned on the to the machine, whereby said carriage maybe moved longitudinally of the machine without obstruction.

low construction, thereby adapte to receive a square plunger 19, formed on the face next track for the movable parts of the machiney inner side ofthe vertical bars with relation' The central bar 14 of the carria e is` of holin alinement with and form, in effect, a convided, surrounding the open mouths of the "therewith, being referably fixed to one of f lIO the vertical bar with a series of transversely-arranged cog-teeth 20. An operating-lever 21 is pivotally mounted on the vertical bar 15 ofthe carriage and provided forward of its pivotal connection with a segment 22, formed on its curved edge with a series of cog-teeth 23, designed to.` projectI through an opening 24, formed in the proximate side of the bar 14 and meshing with the teeth on the plunger 19, whereb to vertically reciprocate said plunger in t e movevmal position the tanks 1 or 2. At its free end the arm 27 is provided with a dependin sup ort 2,8, having a hook 29 at its lower en to etachably receive the eye of a bail 30, connected to a wire or perforate dish-basket 31. The basket is preferably somewhat less in diameter than the diameter of the tanks,

` whereby to provide for the reception of a sufiicient quantity of water within the tank to completely envelop the basket in o eration. The sleeve 26 is provided with a lato -pin 32,

l having its operative end projecting throu h an opening 33, formed in the sleeve. T e operative end of the latch-pin is designed to .engage in one of a series of depressions 34,

formed in a row circumferential of the reduced end of the plunger 19,` whereby to secure the arm 27 in adjusted position with relation to the plunger. The sleeve 26 is also rovided with a handle 35, extending thererom in a direction opposite to that of the arm 27 to'provide for convenient revolution ofthe arm when desired. Itis also desirable to provide means for operating the plunger independent of the lever 21, in orderto adapt the machine for use in situations precluding the use of said lever.` I provide this means by mounting a metallic arm or casting 36 at one side of the upper end of the bar 14, the castinT projecting laterally of said bar and toward the barl. The outer end of the casting is formed withan elongated slot 37 ,i

' having bearing depressions 38 39 at opposite ends thereof. ,A stub-shaft 41, carrying a Apinion 42 and a crank 43, is mounted in the casting, being of a size to iit snugly within the bearing depressions 38 or 39 and .headed at one en" to prevent disconnection from the.

casting. The teeth of the pinion 42 are designed to intermesh with the teeth 20 on the plunger, whereby revolution of the stub-` is out of mesh with the teeth ofthe plunger,

and said plunger may be operated solely by the lever 21. It is to be understood, of course, that in the operation of the plunger by the pinion 42 `the lever 21 is swung to vertical position to Wholly disengage its teeth 23 from the teeth ofthe plunger, as clearly shown in Fig. 1. A dog 44 is pivotally supported on the casting 36 in such position that its operative end may when desired be en'- gaged with the teeth 20 of the plunger 19 to support said yplunger in the desired elevated position.

The eiiiciency of the machine is increased by heating the contents of the cleansing-tank and rinsing-tank, and to this end I mount' burners 45 beneath said tanks, which may be of any suitable type' and are simply designed toheat the contents ofthe tank. Dischargepipes 46 communicate with each of the tanks through its bottom and preferably lead to a suitable sewerage-discharge, thus providing for the convenient draining of the tanks when not in use or when it is desired to replenish the iuid.

Assuming the parts constructed and arranged as described, the o eration of my improved dish-washing mac ine is as follows: The dishesl to be cleansed are placed in the basket 31 (andthe latter hung or supported on the hook-sup ort of part 28. f The arm 27 is revolved unti the basket is centrally located above the central tank 1, it being understood that the carriage 12 has been pre- TOO viously moved longitudinally of the tracks to position it directly opposite the tank 1. The arm 27 is locked in position through the medium of a latch-pin 32 to support the basket centrally above the kcleansing-tank and the plunger 19 ra 'idly reciprocated through operation ofthe ever 21 or crank 43, asmay be preferred, thus subjecting the dishes in the asket to the cleansingy influence of the fluid within the tank 1 in an obvious manner. After the dishes are thoroughly cleansed the carriage is moved longitudinally of the tracks to position the basket 31 above the rinsing-tank 2, Where the operationdescribed is repeated, to thoroughly rinse the dishes. The carriage is then moved longitudinally-.of the tracks to position the basket above the draining-tableand the plunger lowered to depositthe basket with its contained dishes upon the-table.

Itiswhollyobvious that from the initial handling of the dishes to place. them in the basket 31 no further direct contact therewith is' necessary, as all essential positions ofthe dish-basket may be obtained through a longitudinal movement of the carriage or theA the lever 21 or crank 43.

The apparatus in its described details of structure is simple and cheap in manufacture, though thoroughly efficient iii use, and l wish it understood that I do not limit myself to the precise details shown and described, as various changes and modifications thereof may be resorted to without departing from the spirit of my invention.

Having thus described the invention, what is claimed as new is 1. A dish-washing machine comprising a plurality of tanks, a framework for supporting said tanks, a carriage movable longitudinally of the framework, a plungerl mounted for reciprocation in the carriage, and an arm carried by the plunger and arranged above the tanks.,
