Application filedOctober 4, 1909, Serial No. 520,988; Renewed January 21, 1915. Serial No; 3,632. I

To all whom it may concern Be it known thatI, FRANK W. BnARnsLnx a citizen of the United States, and a resident offNew York, Richmond borough, in V 'plpe 3", to the end that cleansing fluid the county of Richmond and Stateof New York, have invented certain new and useful Improvements in Dish-Washing Machines, which improvements are fully set forth in the following specification.

This invention relates to improvements in constructions of that-class commonly known .as dish-washing, machines, the same being availed of for subjecting dishes and analo-' gous' utensils to a' cleansing operation. I The object of this invention is to provlde a machine of the character above indicated which shall be simple and comparatively in expensive as regardsconstruction; durable, efiicient andireliable in practical service; convenle'nt 1n its application to practical purposes; and which shall possess certain Well-' defined advantages over prior analogous constructions 1, v

The invention consists 1n the novelcombinations, parts and details whereby, to

gether with the novel disposition andrelative arrangement of said parts,"the atta1nment of the foregoing object is rendered practicable, all of which will be 'more' specificallyireferred to hereinafter and set forth in the appended claims.

The invention is clearly illustrated the accompanying drawings, wherein similar reference-numerals denote corresponding parts throughout the several views, as to which: v

Figurel is a plan view of a dish-washing machine embodying my said improvements. Fig. 2 is a vertical section of same, as along the line wa2 of Fig. LFig. 3 is a side elevation ofa ,fragme'nt'thereof. Fig. 4 is a transverse section, as along the line y g of Fig. 3. Fig.- 5 is an enlarged detail View showing, in front'el'evationand detached, one of the pendent dish-containers made use of. Fig. 6 is a central, vertical, trans verse section of the construction shown in Fig. '5, and Fig. 7 is a plan view thereof.

In carrying out my invention, reference being had'to-theacc'ompanying drawings, I

make use of a main tank 2, adapted to contain a suitable quantity of cleansing fluid, and preferably divided, as by means of a sprocket-wheels 3 of spindles transverse partition. wall 2", into a washing,

compartment 2 anda rinsing compartment 2- The washing compartment 2" is also provided, by preference, with an overflow may be continuously introduced therein. further make use of a flexible, endless con- ,veyer to which there is pivotally attached a thereto pivotally attached, into and out of the bath of cleansing fluid contained in said tank. Specifically, I- make use of opposite, endless sprocket-chains,

tical planes, the former .on a system 0 like system of sprocket-wheels 3". The sprocket-wheels 3" are mounted, respectively, on-spindles 4, rotating in bracket-- bearings 4', attached to the tank2, ataone side thereof, and the sprocket-wheels '3' are correspondingly. mounted on similar spindles 4", rotating in similar bearings 4", attached to saidtank at the opposite side thereof. i

It is essential that the chains 3, 3', move in unison in the practical operation of the machine, and this notwithstanding each op- 3,v 3', suitably; spaced apart, and operating in parallel verf- 70 and the latter on a erates on its own distinct system of sprocket- 1 wheels. Therefore, I'provide, for the purpose stated, positive driving mechanism,

which is here shown as comprlsing a main "shaft 5, rotatably arranged transversely of the tank 2, atthe forward. end thereof, con- 'sidered with respect to the direction of movement of the general rotating parts the machine, and as in bearings 5' attached to said tank 'exteriorly thereof; sprocket-wheels 5", 5,firmly mounted on said main shaft sprocket-wheels 6, 7, firmly mounted, the former on one of the spindles 4, outside of the tank2, said spindle being extended to 'this end, outwardly through and somewhat beyond the adjacent "side-wallof saidtank, and. the'latter correspondingly mounted on one of the spindles 4, extended, to this end, outwardly through and somewhat beyond the opposite side-wall of said tank, and be ing, by preference, that one of the system 4 which is arranged in axial alinement with that one of the spindles 4, on p which the sprocket-wheel '6 is mounted; and

transmission chains 6, 7', operating, the former onethe sprocket-wheels 6, and

' tion indicated by the arrow 7 f in Fi 5',

the latter on the sprocket-wheels 5", 7, all

as clearly shown in the drawings. Hence,f.

upon shaft 5 being rotated, as in the direcand as through the medium of a pulley gfirmly'moun'ted thereon, and in connection,

as through the mediumof a belt 8,-with any appropriate source of power, its motion will be transmitted to the respective chains 3, 3',

of the washing compartment 2" and into j thev same being pivotally attached to saidconveyer and depending, by its own gravity and at all times, therefrom. Specifically, the dish-container aforenamed comprises a stirrup 8','pivotally attached to the chains.

through the medilllfl' of 1 the driving-mechanism parts above enumerated, to continu-;

'ously move the same in unison into and out and out of the rinsing compartment 2"; In connection with said conveyer I further make use of a noveldish-container, adapted to receive and contain dishes varying quite widely as to size, general contour or depth,

3,3, respec'tively, asat the points '9, 9'-','and

beingthus 'situated between the same and: pendulously depending therefrom; and an openwork basket, the latter rock'ably attaclied to said. stirrup.

.. I The basket aforenamed comprisesavertical back 8", which is provided at its upper, rear edge-portion, considered with reference to the'discharge endof said basket, with. a

' hook 8"-'-, the purpose ofwh ich will be made more apparent hereinafteria front wall 9",

attached to or formed integral with, saidback, and flared upwardly and awaythere:

from; and an" end-segment 9"., connecting" I said back and said front wall, atthe rear.

- edgBe-portions therepf,a1l as clearly indicated" igs. '5, 6 and 7 of the drawings.

The basket .aforehamed is preferably formed from--'sheet metal of appropriate th1ckness 1 ts back, front wall, end-segment and -bottom,= -being,-j respectively, provided I with a'mult'iplicityiof suitable openings, as

10, 'to the.end- -that. the fluidrused in the tank; '2 may s'u'rge freely, various directions, through the same, in the practical operation v ,of the machine; as a whole.

The backB is'projected downwardly at its forward, lower'edge-portion, to form 'a leg 10., terminating in; a forwardly rojeaiing foot 10"; and the-"stirrup 8' hasjan-arm 11, arranged: atright angles thereto along its bottom, -.an d toQ-thefront end of which," arm. the basket aforenamed is 'pivotally at- [passes through thejleg- 10 and the arm 11',-

tached, as means 'of 'a-pivot-'11' ,.which' the front endof the latter lapping alongside ofsaldleg to'permit this mode-of assembling the parts in question, said stirrup and the arm 11 constituting a general frame on which the dish-basket aforenamed'is mounted." The stirrup 8, is also provided at its top with a rearwardly projecting guide-arm 12, g

of movement of the basket aforenamed with respect to said stirrup, or, in other words,

the pivot 11"; and the hook 8"., hereinbe- 'having a curvature concentric with the axis 1 the foot 10 and arm i 11 cooperate to form a jointed counter-brace,-

which in turn cooperates with a vertical guide, consisting'ofopposite, upright guidemembers 12, 12", arranged at opposite sides of the course of movement of the conveyer aforenamed, and'at a suitable point 'therealong. The said guide-members now under consideration are, in this instance, disposed interiorlypf the tank 2,'at the rear end thereof, and are respectively held in position by means of suitable braces, 13, attached thereto and extended therefrom and attached to the adjacent "walls of said'tank, ';as. indicated'inthe drawingsz z I The function of the guide just referred tois totemporarily check any tendency. of the dish-container. :aforenamed, to pendulous movement .with' respect" to the "conveyer aforenamed, and during the dumping or forwardly rocking action of-said basket, as .on the pivot 11; and to facilitate the performance of this function, ,by" said guide, I

arrange theflupright, constituent members thereofat suitable points-toinsure a more or less-sliding engagement thereof, respectively', by the opposite ends of the counterbrace above referred to, and during an ample period.-within.which' the {dumping action of. the basket aforenamed'imay take j place;

Specifically,

1 1 o iguide. members-12., 12?, the onefwith' a 4 longitudinal'channel.'13,.a1id the other .with' a corresponding channel-13' and into which channels,' each bein suitably flared at one or both of its e ds, t e opposite endsof said counter-brace may" directly "enter,- where a I sl ding frictionj betweenthecounter-braceand said guide-members is not objectionable. I

prefer, however, to provide rollersl, 14,at the .opposite ends of the counter-brace aforenamed, which rollers may enter and roll along the channels 13 ,13' '-,'.respectively,. thereby minimizing: the. friction between" said counter-brace and the members 12, 12", in the practical operation of the machine as a whole.

'It is essential that. means he provided whereby, as the dish-container moves along named is caused with the conveyer,"and duri1 1g more or less of the time that said counter-brace is in "engagement with said guide, the basket aforeits dumping or forwardly rocking action; and to this-end I provide the member'12" with a cam-face 14:", located in the line of movement, with the dish-carrier, of the foot '10", or the roller 14' carried thereby, and accordingly within the channel of said niember.. Hence, as the conveyer moves along, the foot 10", or its roller 14', is brought into engagement with said cam-face, and to escape the same, as theconveyer continues to move along, thefoot 10" directly, or indirectly through the medium of the roller carried thereby, is c'aused,,by said cam-face,

' to rock downwardly on the pivot 11?, with the result that the basket aforenamed is caused to rock forwardlyon said pivot; and when said foot shall have relinquished its engagement with said cam-face, said basket, by reason of its own gravity, and by reason of its fulcrum, or axis of movement, being situated forwardly of its .center. of gravity, returns automatically toits normal, upright position within the stirrup 8. Hence, any dish contained within. said basket will, under the forwardly rocked condition thereof, move outwardlytherefrom, *by a sliding or rolling motion, depending on the general contour of. such dish, along the in-.

terior surface or surfaces of said basket with which the dish contacts when placed therein,

and enters any appropriate receptacle, as the trough 15; or, said dish, thus delivered from said basket, may be otherwise taken care of ting the back 85,

.wall 9", interiorly stated. 7. Shallow dishes,

as the user may elect.

To facilitate the delivery of the dish, as

above described, the basket aforenamed is provided with a delivery tongue 10 which may constitute an extension of the bottom thereof. I

To prevent binding of the deeper dishes, as cups,

back 8" and the wall 9", I provide the basket aforenamed with an interior ledge- 15, which may be formed by suitably cuting the material thereof inwardly, said ledge being preferably bowed somewhat downwardly. I- also prefer to provide duplicate ledges 15, at the back 8'? and front dishes of medium depth, as, cups may en age and slide or roll along both of said-1e ges, without any binding tendency between the same'and said back and said front wall, while still deeper dishes, as bowls, may correspondingly engage-and move along either of said ledges, when the basket is tilted as as plates, saucers, and the like, may rest "directly upon, .and correspondingly move along,

automatically to undergo rate of speed, the arbor 16,

at a muchgreater speed.

'bowls, and the like, between the or front wall 9", and bendl toward the other, whereby dashes the cleansingfluld 1n the a of thebasket, so that acting the bottom of said basket, under like conditions, all as in-' fluid contained with in the tank 2.

It is desirable, however, that there be provided, 'at a suitable. point along the course of movement of the conveyer within the bath 'of'cleansing fluid, means for agitating said cleansing fluid, and causing the same 'to forcibly surge through said dishcontainer, attached 'to said conveyer, and hence forcibly impinge against any dish contained in said dish-container. Accordingly, I provide a rotatable dasher 16, preferably of the general-form of a screw-propeller, the same being firmly mounted on an arbor 16, rotating in astufiing-box 16" arranged at the adjacent side-wall of the tank 2, said arbor, hence, projecting o'utwardly and somewhat beyond said side-wall, to admit of the mounting thereon of a pul- 17, which 'is in belt connection, as medium of a belt 17 witha pulley 17 fast on the main shaft 5, the diameters of the pulleys 17 17 being such that when said shaftis rotated at a given and hence the through the dasher 16, will turn appropri The dasher 16v 's s1tuated within the tank 2, and so that the conveyer aforenamed, with the dish-containeror dish-containers attached thereto, traverse the direct-acting face thereof; andfor further agitating the cleansing additional dasher 18, mounted on an arbor 18', working in a stuffing-box 18, said arbor '18 carrying a pulley 19, in belt connection with a pulley 19, also fast on shaft 5, the arbor, pulleys. and belt last referred to being, respectively, duplicates of the corresponding parts hereinbefore mentioned as being arranged between the shaft 5 and the dasher- 16, and relatively ingly.

The arbors 16, alinement, and the direct-acting fac es of the dashers carried thereby, are presented each each dasher, in operation, direction of the other; andthe conveyer moves along a course extending between said dashers, and hence traverses the directface of each. Accordingly, in .the practical operation of the machine as a whole, the cleansing fluid is dashed simultaneously in opposite directions against and through any dish-container, or dish-containers, carried by said; conveyer, with the res'ults'that'a corresponding application of the cleansing fluid is had on any'dish contained fluid, I-purpose to make use of an 18', are arranged in axial 1 in any dish-containertraversing the directacting faces of said dashers, the opposite sides or faces of said dish being accordingly cleansed at a single operation.

To enhance the efliciency of the dashers aforenamed, I purpose to provide the same with shields 19", 19", respectively, said shields bein attached, respectively, to the. opposite. si es of the tank 2, interiorly thereof, and so'as to house, each the upper portion of the dasher with which it coeperatesr 1 It is desirable that meansbe'provided for checking any tendency to pendulous action on the part'of'any' dish-container attached pivotally to the conveyer aforenamed, as the same enters and moves along the bath of cleansin fluid immediately agitated by the dashers 16, 18'; and with'a view to the attainment of this end, Ppurpose to make use of a guide conforming in all essential details to the guide hereinbefore referred to as'being located withinand at the rear end of the tank 2, or the dumping station along the circuit traversed by said conveyer.

- be located at any desired point along said to the adjacent. side-walls of the tank 2;

and each dishcontainer, attached to said conveyer, cooperates with said members 20, 20, so far as the guide constituted thereby performs its function of preventing pendulous movement on the part of-said dishcontainer, in the same manner as it coiiperates with the guide aforenamed. located at "the dumping station along the circuit traversed by said conveyer. It will be under stood that the circuit traversed by the. conveyer may be widely varied to suit the needs or requirements of the user, and further that the dumping station aforenamed lmay circuit.

In practice, the driving parts of the machine having been set in motion, th con-' veyer continuously moves on its respective systems of sprocket-wheels, and along a suitable circuit prescribed therefor, thereby carrying any dish-container attached thereto into the cleansing bath, preferably the compartment 2", .and between'and hence opposite the direct acting face of each of the dashers situated therein; thence out of said bath, and preferably into the rinsing bath contained'in the compartment 2"; thence out of saidrinsing bath to the dumping station' aforenamed, where the basket of said container is rocked forwardly as hereinb'efore described, to allow any disb. .contained in saiddish-container to move outwardly therefrom; and thence along a suitable 1 course to, and again into thewashlng bath,

a dish to be cleansed being placed in each empty container, byan attendant, as said containenmoves along the circuit of the.

conveyer above the tank 2.

It will be seen that my improved dish-.

washing machine is particularly well adapted for the purposes for which it is intended,

and further that the same may be modified to a considerable extent, particularly as regards the specific character of the guide or guides made use of for preventing pendulous movement as hereinbefore specified on the part of any dish-container or dish-com tainers attached to the conveyer, the specific character of "each of the dish-containers made use of, it being primarily essential that the same shall be pivotally attached to the dish-carrier, and desirable that the same .shall comprise arocking basket, and various minor details of the general construction,

without materially departing from the spiritand principle of my invention.
