WASHING MACHINE.

' Application led December 8, 1917. Serial No. 206,285.

To all whom 'it may concern.'

Be it `known that I, GEORGE S. BLAKESLEE, a citizen of the United States, and a resident of Chicago, in the countyl of Cook and State of Illinois, have "invented certainl new and useful Improvementsl in Washing Machines, of which the following is a specification, reference being Jhad to the accom-v 20 position over the washing and rinsing tanks during the washing and rinsing operations, although certain features of the invention may be applied to other types of machine.

A machine of the gravity type is shown and described 1,360,716, granted tome Nov. 30, 1920.

The object of my invention is to provide certain improvements in power operated washing machines,.especially with respect to the mechanism for positioning vthe baskets in a machine of the gravity type; the mechanism for throwing the washing and rinsing water violently into contact'with the articles to be washedand the devices for controlling the operation thereof; and the construction of the shell or vcasing of thel machine; also to rovide improved means for rinsing the articles to be washed. This I accomplish as hereinafter described and as illustrated in the accompanying drawings. vWhat I regard as new will be set forth in the claims.

In the drawings, Fig. 1 is aside elevation of my improved machine;

Fig. 2 is a thereof;

Fig. 3 is a vertical cross-section on line 3-3 of Fig. 1;

Referring to the drawings,

7 indicates the shell or casing of the machine, whichis of suitable shape and d'imensions to enclose and support the various ported on legs 8. Said casing is best made parts of the apparatus, and is preferably supv of sheet metal, and the main body .thereoflv is rectangular in form, as shown/in Figs. 1 and 3. It is provided at its opposite ends jvith laterally extending aprons 9-10, and

with hoods 11-12 which extend over the aprons 9-10. respectively, andare hinged at 13-'-l4 to the upper part of the casing so tha-t they may be swung up out of the way, as illustrated in, dotted lines at the left in serves as a-Water receptacle, and is .provided with a transverse partition 15 which divides the interior thereof intowashing and rinsing compartments 16-17, respectively. Sui-table pipe connections., which need not be specifically described, are provided for supy plying the tanks 16--17 with Waterl and for regulating'- the level of t-he Water therein.

The ends of the easing above the apronsY 9-10 are open to permit of the passage longitudinally through the tank of wheeled basket'18,'shown in dotted lines in Fig. 2, and in 'fulllineslin Figl. These baskets are adapted to hold the dishes or other articles to be washed, and are adapted to run on tracks 19-20 which extend longitudinally through the casingand over the aprons 9-10, as shown in Figs. 2 and 3. Said tracks, which are preferably made of angle iron, are inclined downward from the 1nlet end A to the outlet end B ofthe mai chine, so .that the baskets are adapted to move by gravity through the machine from the inlet end-.tgAthe outlet end thereof. At the Alatter'endian up-turned stop 21 is prof vided to prevent the baskets from running olif the track at that end, as shown in Fig. 2. The baskets 18 are provided at their ends with inclined guides 22, as best shown in lFig. 2, the guidessof adjoining baskets bein adapted to register, so that they serve to ho d the baskets apart and also co-operate with the sliding gate hereinafter described, to roperly posit-ion the baskets in the was ing compartment.

23 indicates avertically-sliding gate which is mounted in the casing in line with the partition 15, with which it is adapted to cooperate to separate the washing com artment from the rinsing compartment a ove the level of the water in the tanks 16-17. Said gate is 'substantially counterbalanced by a counterbalance weight 24, which, in

' the construction shown, is connected to the vas.

gate above the casing by a flexible connection 25 which runs over pulleys 26-27, as best shown in Fig. 3. 'The gate 23 is raised and lowered by means of a controlling device which also controls the operation of various other parts of the machine, as will be hereinafter described. ln the construction illustrated this controllingl device is in the form of a lever 28 of the bell-crank type, the fulcrum 29 of which is adjacent to the inlet end of the machine, said, lever having an upwardly extending arm 30 which is provided with a handle 31 placed in position for convenient operation by the attendant who introduces the baskets into the machine. The other principal arm 32 of said lever is connected by a. link. 33 with a longitudinally movable rod 34 which is mounted at one side pf vthe casing in suitable brackets 35-36 and is connected by a horizontal arm 37 with the upper portion of the gate 23, asY shown in Fig. 3. Thus, by 'rocking the lever 28, the gate 23` may be raised and lowered.' To permit of the passage of the lower edge of said gate into contact with the partition 15, the tracks 19-20 are made in sections which are separated slightly at the center of the machine, as best shown in Fig. 2, so that when said gate is lowered it may pass between the adjoining ends of the track sections.

For the purpose of throwing the wash ing and rinsing water in the tanks 16-'17 violently into contact with the articles to be washed, ll provide .paddle 'wheels 38-39 Vwhich are mounted in the tanks itl-17, re-

spectively, and extend longitudinally thereof in such position that their blades dip into the water in said tanks. Said paddle wheels are mounted on a lngitudinally entending shaft 4:0 suitably journaled in the ends of the casing and connected by a flexible clutch or coupling l1 with the armature 'shaft l2 of an electric motor 43, which, in

theconstruction shown, is mounted @n pasaste suitable support tl at onel end of the machine. lPVhen the motor is in operation the shaft et() will be rotated, thereby rotating the paddle wheels and throwing the water in the washing and rinsing tanks upward, and

Asince the paddle Wheel shaft is connected directly to the armature Shaft of the motor,

said paddle wheels will be rotated at a high rate of speed, thereby causing a very pronounced and forcible distribution of the water `throughout the Washing and `rinsing compartments. This construction makes it practicable to employ much smaller paddle wheels than it has heretofore been expedient to' use. As best shown in Fig. 3, the paddle wheels are located substantially centrally under the path of the baskets 18 instead of at one side thereof, as has heretofore been-the practice, and consequently the machine may be made muchnarrower, and occupies considerably less space. lin order to properly direct the water thrown by the paddle wheels up against the contents of the baskets, vertically extending deflectors 45 are provided, in the form of plates which may 4paddle wheel 39, ll also provide for rinsing them a second time b-y spraying them with fresh hot water while they are passing out of thesrinsing compartment. For this purpose l provide a spraying pipe 46, which` in the construction shown, .extends trans? versely` ofthe machine below the "path of the baskets and adjacent to the outlet end of the rinsing compartment. This spray- 'ing pipe may, however, be 'placed above the baskets if desired. Said pipe is sup'- plied with hot water under pressure and it is perforated in such manner that the water will be discharged upon the contents of the basket in the rinsing compartment as it moves over said pipe. nected with a suitable source of suppl)7 of hot water, indicated by a pipe 47 in Fig. l, the supply of water admitted to the pipe 46 being controlled 'by a valve ,48 having a projecting plunger stem 49. This valve` in the form illustrated, is so` constructed that by pressing in the stem a9, the valve will be Said pipe is conopened and water admitted to the pipe d6.

' arm- 52 which is connected by a link 53 with valve shown is automatically opened to discharge rinsing water upon the contents of each basket as it moves out of the rinsing compartment will presently be described.

50 indicates a rock-shaft which extends transversely of the machine below the tracks 19-20 and adjacent to the outlet end of the rinsing compartment, as shown-in Fig. 2. Said shaft carries one or more stops 51 which are adapted to project up into the path of the baskets,vto position them in -the rinsing compartment, or to be folded down by the rocking of the shaft 50, out

of the way of the baskets to permit them to pass out of said compartment. Said rock-shaft is provided. at one end with an the arm 3() of the lever 28, the arrangement y., being such that when said lever is operated 51 out of operative position.

to raise the'gate 23, it also rocks the shaft 50 in such direction as to move the stop Then said lever is moved in the reverse direction, the gate 23 is moved down into boperative position, and the stop 51 is restored to the position shown in Fig. 2. At its otherendthe rock-shaft 50 carries another arm 54 which is connected by a link 55' with alever 56, as best shown in Fig. 4. 'Said lever is mounted upon a pivot 57, and is provided with an arm 58?which is 'adapted to bear upon 'the plunger stem 49. It will be evident from a comparison of Figs'. 1, 2 and 4 that when the lever 28 is moved in a clockwise direction, the shaft 50 will be rocked to move thestop 51 in a counterclockwise direction out of operative position. This movement of the rock-shaft 50 will rock the lever. 54 Iin a clockwise direc-tion as seen intthe illustration of Fig. 4; and

. consequently thelever 56 will'be actuated to press the plunger stern 49 in, or to the lett, thereby opening the valve 48 and discharging a spray of water from the pipe 46 upon the contents of the basket in the rinsing compartment. As soon as the stop 51 is movedv ont of operative position as l, described, the basketv in the rinsing comj the motor 43. For this purpose saidV 'lever partment will move by gravity out over the apron 10, passing over the pipe 46, sothat its contents will beV thoroughly sprayed by the water discharged from saidpipe. This water is maintained ata high temperature so that it e-vaporates quickly, and consequently the rinsedarticles dry almost instantly. i

In order to 'stop the paddle wheels whilelthis last rinsing isbeing eected, and also while a fresh basket vis) being introduced at the inlet end of the machine and the basket then in the washing compartment' ismovingv into the rinsingcompartment, the lever 28 is also arranged `to automatically start and stop is provided 'with an arm 59 from which portion 61 and laterally projecting lugs 62-63, as shown'in Figfl. Saidrod eX- tends through a guide bracket 64 and adjacent to a switch member 65 which controlsthe operation of the motor. It will be evident that when the rod moves longitudinally, the passage of the oset portion 61 through the guide-bracket 64 swings said The lugs 62-63 together rod laterally. form a recess 66 which is adapted to rec'eiye a portion, such as the handle, of the switch'member 65 when the rod 60 is moved laterally at the proper time. The arrangement is such that when the 4gate 23 is closed and the stop 51 is' in operative position, the switch member will be closed and the motor 43 in operation. At this time the lugs 62-63 will be in operative enga-gement .with the'switch member65, and consequently when thelever 28 .is operated to open the switch 23, the same operation will move the rod 60 downward, thereby opening the switch -and stopping the motor,

which also stops the paddle wheels 38--39. This occurs during the first part of the depends a swinging rod 6() havingan offset movement of the rodl 60. As such downv ward movement continues the offset portion will swing the rod 60 laterally so as to disengage it from the switch member 65,y and thereby permit said rod to continue its downward movement without further movement of said switch member. When the lever 28 is moved in the reverse direction, the rod 60 will not operatively engage and actuate the switch until its movement has been almost completed, and consequently lthe motor will not start until the gate 23 the machine, a basket ycon- .no

being sprayed from the pipe 46 into therinsing compartment. As soonl as ,the first basket has moved down into the washing compartment, the lever 28 is operated to lower-'the' gate '2.3, and the operation of said leverstartsthe motor, and. rocks theshaft v50 to turn the stop 51 into operative position and shut thepvalve 48l to cut 0E' the rinsing spray. The starting of the motor rotates the paddle wheels, and'consequently throws Washing and 'rinsing water ses to pass down into engagement with the par-V tition l5. The rinsing of the dishes byV means of the paddle wheel, and the subse quent rinsing by the spray mechanism, have already been described. 'lhe hingin'g of the hoods which extend over the aprons 9 1() permitting it to move through said casing.

-facilitates access to the interior of the casing. h
