Application filed March 20, 1919. Serial No. 283,722.

To all whom it may concern:

Be it known that I, Gnonor. S. BLAKEsLn-n a citizen of the United States, and a. resident of Chica o, in the county of Cookand State of Illinois, have invented certain new and useful Improvements in Washing Machines, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to machines for washing dishes and similar articles, and has for its object to provide a comparatively small, compact and cheap machine suitable for use in situations where large and expensive machines are. not required. a I accomplish this object as illustrated in the accompanying drawings and as hereinafter described. What I regard as new is set forth in the claims.

In the drawings,-

Fig. 1 is a side elevation of my improved machine, certain parts being broken away;

Fig. 2 is a plan view thereof, part of the housing being broken away;

Fig. 3 is an enlarged detail, being a partial vertical section on line 33 of Fig. 2;

Fig. 4 is a side elevation, partly broken away, showing a modified arrangement; and

Fig. 5 is an enlarged perspective view showing the mechanism for controlling the operation of the rinsing device which may be used in connection with either of the forms illustrated in Figs. 1 and 4.

Referring to the drawings,-6 indicates the housing of the machine which is pro: vided with an opening 7 at one end, as best shown in Figs. 1 and 5. The opposite end of the housing is closed and the articles to be washed are placed in containers or baskets 8 which are introduced into and removed from the machine through the opening 7. The lower portion of the housing 6 forms a tank 9 adapted to contain wash water, and the baskets 8' are supported as they are moved into or withdrawn from the machine on rails 10 which extend through the opening? and back to the inner end of the housing, said rails bein inclined downwardly toward the inner en of the housing, as shown in Figs. 1 and 4. The housing is preferably about twice as long as the baskets 8, and in, order that the baskets ma be conveniently handled they are provi ed at one end with a rod or handle 11 long enough to extend out beyond the housing when the basket is in its innermost position, as best shown in Fi 1. Preferably the baskets are provided wit wheels so that they run easily on the rails 10, but if desired they may be arranged to slide on said rails.

12 indicates a drain pipe connectin with the lower portion ofthe tank 9 an leading to a discharge pipe 13, and 14 indicates an overflow pipe connected'with the tank 9; The overflow at the desired water level. p pe 14 also connects with the dischar e pipe 13, and if desired it may be made a {ustable in any convenient way so thatthe evel of the water in the tank 9 may be varied. 15 indicates a door in the upper portion of the housing 6 at one side there of, so-that access may be conveniently had to the interior of the housing near its inner end. This door is kept closed except when some emergency makes it necessary for the operator to have access to the inner end of the housing.

At the inner end of the housing I provide means such as a paddle wheel for throwing water from the tank 9 violently upon the articles to be washed. In the construction shown in Figs. 1' and 2 I have shown for this purpose a paddle wheel 16' mounted in a lateral extension 17 of the housing 6 upon a shaft 18. This shaft is provided with a gear 19 which meshes with a pinion 20 mounted on a shaft 21 which carries a pulley 22. This pulley is driven by a belt 23 which runs over a pulley 24 mounted on the armature shaft 25 of a motor 26, which, as shown in Fig. 1, is mounted on the housing 6. The paddle wheel 16 dips, into the water in the tank 9 and by its rotation takes up the water and throws it violently upon the articles in the basket 8 when said basket is in its innermost po sition shown in Figs. 1 and 2. In Fig. 4 I have shown a mo ifiecb arrangement comrising a paddle wheel 27 which is mounted in the tank 9 below the rails 10 and adp is normally from the tank is thrown by the paddle wheel 27 up against and through the articles in the basket instead of being thrown down upon them as is the ease in the construction first described. This modification is only generically included in this application, as specificially it forms a art of my copending application, Serial 0. 337,001, filed November 10, 1919.

F or rinsing the articles after they have been washed I provide a pipe 33 which connects with a head 34 secured on top of the housing and extending across the same near its outer or open end. The head 34 is provided at its under side with perfora-' tions 35 which register with a transverse slot 36 in the top of the housing, as shown in Fig. 3. By this construction, when water under pressure is admitted to the head 34 it will be sprayed downwardly into the housing adjacent to the opening 7 thereof. By this arrangement, after the dishes contained in the basket 8 have been washed at the inner end of the housing the basket is partly drawn outuntil it underlies the head 34 when its contents are rinsed by the Water discharged from said head. It is desirable that the rinsing'operation be antomatically performed as the basket is drawn out, and be continued as long as any part of the basket remains within the housmg; also that the rinsing apparatus remain inoperative when a basket is introduced into the machine and while thewashing operation is being performed. For this purpose I provide the mechanism best shown in Fig. 5. Referring particularly to said figure, 37 indicates a hot water supply pipe WhlCh connects with the pipe 33, a valve 38 being interposed between said pipes. 39 indicates the valve stem of said valve which held projected by a spring (not shown). 40 indicates a lever mounted on a pivot 41 carried by a bracket 42 preferably secured on the body of the valve 38, said lever having an arm 43 which extends over the valve stem 39 and operates when the lever 40 is rocked in a counterclockwise direction as viewed in Fig. 5 to depress the valve stem 39 and open the valve, thereby admitting water from the pipe 37 to the head 34. -The opposite armof the lever 40 is connected to a rod 44 mounted in a bracket 45secured to the side "of the housing 6 as shown. '47 indicates an adjustable block carried by the rod 44 and having a pin 48 at its under side. 49 indicates a vertically dlsposed shaftmounted in brackets 50 secured to the side of the casing 6. At its upper end-said shaft carries a crank 51 to which is connected, a bar 52having its rear portion slotted, as shown at 53 in said gure. Said slot is adapted to receive the pm 48 which slides freely therein. 54 indicates a spring connected at one end with of the basket as it is moved into or out of the housing. It will be apparent that when a basket is moved into the housing it will engage the arm 55 and rock the shaft 49 in a clockwise direction, as viewed in Fig. 5, thereby moving the bar 52 endwise to the left. This, however, will not open the valve 30 because the slot 53 will permit the bar 52 to move independently of the block 47. When the basket passes beyond the arm 55 the spring 54 will restore the parts to the position shown in said figure so that the arm 55 will be in position to intercept the basket when it is withdrawn from the machine. Upon the withdrawal of the basket it will again engage said arm and will rock the shaft 49 in the opposite direction there by moving the bar 52 endwise to the right. The unslotted portion of said bar will therefore bear against the pin 48 and consequently will move the rod 44 endwise to the right, rocking the,lever 40 and opening the valve 38, thereby discharging rinsing water upon the articles contained in the basket. This will continue as long as any portion of the basket remains in t-he'machine, since the arm 55 will not be permitted to return to its normal position until after the basket clears it. When the arm 55 is released by the withdrawal of the basket said arm is restored to its normal position shown in Fig. 5 by the spring in the valve 38 which projects the stem 39 and thereby rocks the lever 40 in a clockwise direction, moving the arm 44 to the left until it reaches the position shown in said figure. This movement of the rod 44 moves the slotted bar 52 correspondingly through the block 47, the pin 48 of which then lies in the inner end of the slot 53. By this construction the introduction of a basket into the machine does not operate the rinsing mechanism, but such mechanism is operated when the basket is withdrawn.

57 indicates a guard for the lower end of the shaft 49. 58 indicates an inclined tray or' apron which extends out from the opening' 7 and serves to return to the tank 9 any water that may splash out through said opening. 59 indicates a hot water pipe which leads to the tank 9 and is connected with the pipe 37 which leads to the valve 38. 60 indicates a cold water pipe which also leads to the tank 9.
