Fig. 11 is a fragmentary detail view of the switch .and switch operating device shown in a different position from that indicated in Fig. 1. f

The numeral 12 indicates a rectangular skeleton frame in which a sheet metal water tank 13 is mounted and held in an elevated position. The ends of the tank 1 3 a're flat and parallel, and the body'thereof in longitudinal vertical section is in the form of 'an ovoid with itsapex at the bottom of said tank. To afford access to the interior of the tank 13, the segmental top section thereof, above the frame 12, is made displaceable. Extending'transversely through the tank 13 at the axis of the segmental top section thereof is a horizontal Shaft 14 journaled in bearings 15 on the lower body section of said tank.

A receiving opening 16 is formed in the than the receiving opening 16, for a pur' pose that will presently appear. Receiving and delivery tables 18 and 19, respectively, are hinged at 20 to the frame 12 at the lower edges of the openings 16 and 17 respectively, i

for outward and downward swinging movementand are held raised by releasable braces i 21. It will benoted that the inner edge portio'ns of the tables 18 andl19, when raised,

extend slightly into the-tank 13 through the openings 16 and 17, respectively, for a purpose that will hereinafter appear. `In View of the different elevations of the openings 16 and 17, the tables 18 and 19 are, of course, correspondingly located in respect to each other Aand, the water line in the tank 13 is just below the receiving opening 16.

A n agitator in the form of a propeller 22 is mounted to rotate about a vertical axis at the bottom of the'tank 13 at the transverse center thereof. Said propeller 22 has a depending shaft 23 jounaledto a water-tight bearing y24: on the underside of the tank 13 and'said shaft is also journaled in the top i 'and bottom members of a housing 25 secured to a shelf 26 on the frame 12. A. worm gear 27'is secured to the intermediate portion of the shaft 23 and meshes with a worm 28 on a horizontal shaft 29 journaled in bearings -on the'ends of the housing'25. Said shaft 29 extends parallel to the shaft 14 and' is conr nectedb a, universal joint 30 to the armature sha `31 ofan electric motor `32 mounted on the shelf 26.

Formed with' the tank 13, on the back thereof, is a narrow, but deep, overflow'compartment 3 3 which extends substantially the full .width of said tank.A The to of the comj partment 33 is -just below the elivery table` raised. A large waste pipe 34 leads from'l the bottom of Vthe overllow compartment 33. lIn the back of the tank 13, just above the water level is a narrow opening 35 which extends :substantially the full width'of the tank 13. The' purpose of this opening is for the overaw ef the washing water from the 19 and is closed thereby when said tablev is' tank 13 to the compartment 33 and for the discharge of the rinsing water into said coml arms 36 of each integrally formed pai'rlare edgewise spacedin vertical planes and located on opposite sides of'the shaft 14, so that when in horizontal position, said arms are substantially yat the vertical center of the delivery openings 17 and l18, respectively. The arms 36 of each laterally spaced pair are, ofl course, in theI same plane. In each arm 36 is formed a rectangular slot 37 which extends substantially the full length thereof.

A. cross-head 38 is slidably mounted in each slot 37, and is provided with an antifriction'roller 39 arranged to run on opposite longitudinal edges of the arm 36 at said slot. The cross-heads 38 have outer side plates which overlap the arms 36 attheir slots 37, and hold said cross-heads for straight line sliding movement on said arms and against lateral inward movement.


Trams 40'areprovided for controlling the movements of the cross-heads 38 and cause the same to maintain constant relation t6- the contour of the ovoid formation'of the tank 13. Eaach tram 40 comprises a stem 41 having on' its outer end a bifurcated head 42 in which is journaled a roller 43. The inner ends of the stems 41 extend into recesses in the outer ends of the cross-heads 38 and are connected to said cross-heads b trunnions 44. The stems 41 extend long1- tudinally through the slots 37 land work between antifriction rollers 45 in the apertured outer ends of the-arms 36. The rollers 43 of the trams 40 are arranged to run on lat track rails 46 secured to the tank 13 at the ends thereof, and follow the contour vof the .ovpid formation of said tank. The heads 42 of the trams are arranged to engage the outer ends of the arms 36 as stops to limit the'inward slidingmovement of the cross- .heads 38. Duringthe` travel of the arms 36 when below their horizontal positions, the trams 40 are projected under the action of gravity, and this movement is controlled by the rollers 43 on the track rails 46.

For each laterally spaced pair of arms 36 is a relatively heavy pivotally mounted f gravity-suspendedv U-shaped track-carrying bar 47, the arms of which are rigidly secured to .the trunnions 44, 'which vsupport said bar for horizontal swinging movement. A. pair'of 4basket-carrying track rails 48 are rigidly Nsecured in horizontal positions to the arms of l each U-shaped bar 47. The track rails 48 of each pair are in the form of angles,the vertical anges ofwhich are'turned upward and vthe horizontal flanges lof which are extended toward each other.

flanges. Rigidly secured to eaclr keeper 49 4 is a weighted arm 50 pivoted at the backs of the vertical flanges of the track rails 48.

Tliese' weighted arms 50 are arranged to yieldingly `hold the keepers .49 operative, as best slviown in Figs. 6 and 8, and the horizontal members of said keepers engage @the horizontal flanges of the track rails 48 as stops to limit the lifting movement of said keepers bythe weighted arms 50. By pressing down on the keepers 49 against the action of the weighted arms 50, said keepers may be Gmoved below. the upper faces of the horizontal fianges of the track rails 48 so vthat said track rails are unobstructed, for a purpose that will presently appear.- At the time the keepers 49 are moved .below the track'rails 48, the weighted arms 50 are I moved beyond dead centers and the horizontal members of said keepers engage said.

track rails as stops, andthereby hold said keepers inoperative, as shown by in Fig, 8.

Awire dish-holding basket 51 is removably mounted ony and suspended between each air of track rails 48, and is designed vto in ividually hold dishes y, as best shown in Fig. 2. When the baskets 51 are, placed oken linesk on the track rails 48,1'the vertical ianges of said rails hold said baskets against endwise shifting movement and the keepers 49 hold said baskets' against lateral shifting movement. These dishiholding baskets 51 may be supported orreither table 18 or 19 and freely moved through either opening 16 or 17 in the tank 13.- The@ shaft 14 is driven to slowly rotate the arms 36 from the shaft 23, driven from the 1motor 32, by a sprocket chain 52 which runs'over enlarge sprocket wheel 53Zrigilly secured to theright-hand end of said shaft, outward of the tank 13, and a relatively small sprocket wheel 54 on the outer member of a two-part shaft 55,

which extends parallel to the shaft 29 and is journalled in a bearing 56 on the frame 12:

The inner member of the shaft 55 is journaled in the housing25 and is provided with a beveled gear .57 which meshes with a beveled'gear 58 on theshaft 23. The memo bers of the shaft 55 may be connected and disconnected, at will, by a clutch 59, the

movable member of. which is provided with a shipper collar. To' this shipperjcollar is applied a laterally movable shipper lever 60 having, a cross rod 61 slidably mounted in lbearings l62 on the front of the frame 12.

',At the bottom of the tank 13 is a valveequipped drain pipe 63 through which the washing water in the tank `-1.55 may be drained from said tank.

The arms 36 are rotated in the direction of the arrow marked on Fig. `3 from a positiony inwhich the basket 51 atv the opening 16 is carried thereby downward through the body of the Water in'thetank 13 and then upward and out of the Water on theopposite side of said tank andl positioned' in front of the opening 17. At this same time the other basket 51, at the opening 17, is moved above the Water and positione'din lfront of the opening 16.` l During this movementof the baskets 51, the sameare held from turning by the turning of the trunnions 44 in the cross-heads 38, under the action rof the heavy U-shaped bars 47 and the suspension of said baskets'below said trunnions.

'Aftera basket 51 has been lifted from the washing Water during vits travelling .movement, the vdishes y are rinsedby clean, hot Water in a novel manner Whichvincludes upper and llower nozzle pipes 64 and 65, respectively, arranged to` spray toward each other, as' indicated by the arrows, asbestv shown in Fig. 3. '-These nozzle pipes 64 and 65 eX- tend parallel-to theshaft 14, and project outward throughsegmental open slots 66 and 67, respectively, in the Vright-hand end of the' tank 13. Said nozzle pipes 64 and 65 are inthe form of laterals on an'upright oscillatory Water pipe 68, the lower end of which ,is extended laterally and `jo'urnaled in a water-tight bearing 69 o n the discharge end of a hotwater supplypipe. 70 leading from any suitable source yotsup'ply under pressure.. 1 l

interposed in the Water supply pipe'70 isa, rotary valver 71 having a crank arm 72 yconnected by'a'llinkv 73v to the long end of a lever 74 intermediately. pivoted to a part on the frame '12.' `The-short. end of the lever is -p'rovidedlwith a cam'groove 75 in 'which isV a cam `pin 76 on al clamp 77 applied.

to the oscillatoryy water pipe 68. The action ofthe cain'pin 76 onthe cam ,groove 75 in the lever74, duringthe' oscillation of the y water' pipeV 68,'1is v`such as to operate said 'levert and intermittentlyl open and close the valve 71 in timed relation to the.y oscillations ofsaid pipe. Normally, vthe pipe 68 is positioned, as i indicated l'in Fig. 3, Wit-h the nozzle pipes 64 and 65 outside of the tank13, and at which timefthe valve `71 is closed.

During the' movement of these nozzle pipes 64 and 65 'to the inner'ends ofthe slots 66 and 67 and their return, the valve 71 is open sothat rinsingkwaterisdischarged from said *f nozzlev pipes. n,

Theoscillat'oryI Water pipe 68 isv yieldingly held in its inoperative position ,as shown by full linesin Fig. 3, by av weight 78 adjustably mounted on 'a radiallyfexte'nded arm 7 9 rigidly` secured tothe clamp77. jA strap 80 is secured to theftank 13, across the open outer end of the lslot66 to be engaged by the nozzle pipe 64l as a stop to limit the outward swinging movement of the .oscillatory pipe 68, under the action of the Weight 78. 1

To move the Waterpipe 68 from its inoper` ative position as shown by full lines in Fig. 3`to its innermost position, as shown by full lines in Fig. 4, and then release 'the same,

there is provided an upright lever 81 inter-l mediately pivoted at 82 to the right-hand end of the tank 13. The lower end of this lever 81v is connected by a link 83 to the clamp 77 and its upper end has a cam finger 84 arranged to be alternately engaged by a pair of cam lugs 85 on certain of the arms of the sprocket Wheel 53, and which lugs 65 during their spraying action to' rinse the: I

dishes y in said basket.

To collect the rinsing water from the nozzle pipes 64 and 65, and discharge the same.

there is provided a concavo-conve'i drain board 86 hinged at 87 to the tank 13 and extends into said tank throughthe overow opening 35. This drain board 86 is arranged for vertical swinging movement from ay position, in which it hangs down in washing p Water in the tank 13 andrests in an inoperative position against the inner Wall of saidA tank, to an operative position, as shown by full lines in Fig. 3, in which it is in an inclined position above they Water line On the ends of the drain board 86 are shallow anges 88 Which hold the rinsing Water thereon.

To raise the drain board 86 to an operative position in timed relation to the moivement of one of the baskets 51 out' of the Washing water to a rinsing position, there is secured to one end of the hinge rod of said drain board a-.crank-acting cam arm 89. This cam arm 89 is arranged to be engaged by one end of alever 90 intermediately secured to the left-hand end of the shaft 14. Once durin each half rotation of said shaft, the drainoard 86 is lifted to an operative position and thus held during each rinsing action and then said 'arm is released to permitthe drain board 86 to return by operative position in the Washing Water.

This drain board 86 also Vperforms another important function in that it acts as a skimmer to lift solids'from the Washing Water and discharges the same through the opening 35 into the-overflow compartment 33. During the lifting movement of the `drain board 86, there will be suiiicient Washing Water thereon y to carry with it the solids and discharge the gravity to an inlio Furthermore, the rinsing water will also carry' oi any solids remalning on the drain board 86. g

To sotart and stop the motor 32when the baskets 51 are in loadin and unloading positions, there is rovi ed an automatic switch-operating' device that is automatically operated to open the switch and manually released to automatically close the switch. This device includes a double switch 91 mounted on the frame 12 and electrically connected by wires 92 to the motor 32. Said switch .91 is alternately opened and closed by an oscillatory fork 93 pivoted to` said frame with its lprongs embracing the switch to engage the diametrically opposite push buttonsr thereof, asbest shown 1n Fig. 11 A coil spring 94, attached to the fork and anchored to the frame 12, is under strain to move said orkA into a position to open the switch 91, as Vshown in Fig. 1. To oscillate the fork 93 a ainstthe tension of the spring 94 and there y close the switch 91, there 1s mounted in a pair of aligned. ears 95 on the fork-93, a flat stop platehaving on its outer end a finger piece 96. This stop plate 96 is held by a coil lspring 97 projected in the path of movement of the lever 90 to be engaged thereby once during each half rotation of said lever, or in other words, to be alternately engaged by the ends of said lever. At the time the stop plate 96 is engaged by the lever 90, the fork 93 is oscillated against the tension ofV its spring l94 and thereby operates the switch to sto the motor, as shown in Fig. 11,'with the askets 51 op site the opemngs 16 and 17 in the tank 13.'

To close the switch 91 and thereby start the motor 32,'the stop plate 96 is manually operated against the tension of itsv spring 97 to release the fork 93, held by the lever 90, and fork an' therebyclose the switch 91. 1

'-1 Operation.

The operation washing and rinsingmachine may be briey described as 'followst vIt may i that the machine idle with the clutch 59 released, .the a s 36 positioned with the basket-carrying tracks 48 in horizontal posiin inoperative tions in which one pair thereof ids opposite the opening 16 andthe other pairthereof is opposite the opening 17, as shownin Fig. 3, withv the nozzle pipes 64 and 65 held positions outside of the tank 13 by the weight 78, fasshown by broken lines in Fig. 3, with the'valve 71 closed and the switch 91 held closed by the fork 93 which in turn is held'by the lever 90 against the action of the sprino 94. Itmay also` be assumed that the drain pipe' 63f is closed filled )with hotr water up to and the tank 13 the water 'line w' and`containing the necessary amount fof washing powder.'

from has just been connected to the inner section,

rmit its spring 94 to oscillate saidv of the above described dish be assumed i32, and drive the propeller 22 to agitate the water inthe tank 13 and mix the washing powder therewith' to produce suds. The basket 51 at the opening 16 is then removed and filled with dishes to be washed. The filled basket 51 is then placed on the receiving table 18 in its proper relation to the adjacent track rails 48, and the outer keepers 49 are moved into inoperative positions and held b their arms 50. Said basket 51 'is then s id from the table 18 into the tank 13 through rthe opening 16 and over the track rails 48 and the keepers 49 are closed. It is important that the extension of the table into the tank 13 kee s the filled basket 51 out of contact with the rails 48 before said sor basket' is lowered thereon in order not to tip said rails, which are gravity? held. In fillin the basket 51, the o erator so places the dishes that the load wi l be quite evenly and thereby rotate the arms 36 by means4 of the driving connections 52, 53 and 54 the outer section of the shaft 55, which of said shaft by the clutch -59.

During the rotation of the arms 36, the

filled Abasket 51 .is carried downward into the water and then out of the same on the opposite sidevo the tank 13. During thismovement'of the filled basket 51 through the water, the respective trams 40,' acting on their cross-heads 38, permit the basket to travel away and thereby enter the water to substantially i-ts full depth. Due to fthe peculiar shape of the tank 13, a minimum amount of Awater is required to'ill the same and hence'a relafrom the axis of the shaft 14 A tively small quantity of the washing powderl is required.

of the shaft 15 per-mits said basket to travel hence'- has the same eect Water.

v This mounting of lthe basketl `51 for movemept'toward and from theaxis The propeller 22, due to its location at the bottom of the .tank 13 and the opera` tionof its blades close tothe relativelyvsteep front and back wallsof said tank, notonly sets up a whirling motionofthe 'waterin said tank, but forces the water in opposite directions up the front and rear walls of theN tank 13, and thereby causes the same to break and `fallback into the cente of the tank 13 over the propeller 22. It will thus be seen that during the movement ofthe filled basket 51 through the,washing water, said un. l a greater distance v through the water and A as a large body of water is forcedv through the basket and around the dishes in all directions which thoroughly and quickly cleanses the same,

When the filled basket 51 is opposite the drain board 68 during its movement out of the water, the cam arm `9 is engaged by one eId of the lever 90 and operated to cause said drain board to follow 51 out-of the water and be held in an operative positionrunder said basket. -During this same time, the cam finger 84 on the lever 8l' is engaged by one of the cam lugs 85 and the said lever operated to swing the water pipe 68 inward and thereby carry the nozzle pipes 64 and 65 into the tank 13 at the time the filled basket is between the same. -As the water pipe 68 swings inward, the valve 71 is opened by the connections 72, 73 and 74 under the action of the cam pin valve.71, a spraying action is set vup by the nozzle pipes`64 and 65 in which jets of hot water, under pressure, are directed onto the dishes in the filled baskets 51 from the top and the bottom of said baskets and at various different angles during the travel of said nozzle pipes. It will thus be'seen that the dishes in the filled baskets 51 are thoroughly and quickly rinsed with hot water., v

At the time the cam lug moves out of engagement with the cam finger 84 Vandl releases the lever 8,1, the weight 78 returns the water pipe 68 to a normal position. in which the nozzle pipes 64 and 65 are again positioned outside of the tank 13. When the arms 36 have made one-half rotation, the lever engages the stop plate 96 and thereby rocks the fork 93 which operates the switch 91 and closes thesame to stop the motor 32. At the completion of this onehalf rotation of the arms 36, the filled basket 51, which has just been rinsed, is positioned directly opposite the opening17- and the empty basket 51 is directly opposite the opening 16. The outerfkeepers 49, holding the filled basket 51, are now turned into inoperative positions and the basket filled with rinsed dishes is drawn from the track rails 48 onto the delivery table 19, which projects into the tank 13, 'and through the opening 17. At the timethe'filled basket 51 is revmoved from the opening 17, the empty basket 5 1 is so positioned that the same mayV be removed through the opening 16 and filled with dishes to be washed.

The above described machine is so designed. that the same may be placed in various different positionsin respect to wall space as either side thereof may be turned against a wall without interfering with the operation of the machine, and in case there is not suflicient room for the use of the delivery opening 17 the basket of rinsed dishes may be carried on' around in ,the/machine the filled basket 76. With the opening of theand removed through the opening 16. The q constructiony and action of the machine is such that an electric motor of small horse power may be used to operate the same. The novel and efficient manner in which the dishes are -rinsed requires the use of very little water.

It will be noted that the clutch 59 is so arrangedv that the baskets may be operated or stopped while rthe agitator is in operation without effecting the action thereof. This A arrangement of the clutch 59 is' highly important in that in casethe dishes longer time in which to cleanse the same than that during a continuous travel through the water, said clutch may be operated to stop require a l the driving connections to the shaft 14 While is in the washing water the dishes to soak.
