Be it known that I, ANTON C. Scnmnnzan, born ;in Hungary of Hungarian parents, now believing myself to bee. citizen of that formally declared my United States'of America in conformance with the United States immigration laws,

Springfield, in the State of Massachusetts, United States of America,.ha've in: vented certain new and useful Improvements in lVashing Machines, of which the following is a specification.

This invention relates to washing machines, and, more particularly, to machines and now residing at 10 county of Hampden and for washing and rinsing or sterilizing drinking glasses, dishes and other articles of'llke nature.

a washing machine, wherein washing and rinsing water may be delivered into the washing compartment of the machine through separate and independently con- 2 trolled means, and wherein timing mechanism is employed to actuate the'controlling device of each such means at properly timed intervals.

Another object of the invention is to provide in a machine of the classdescribed, a

driving means for the timing mechanism arranged to utilize some of rinsing water as motive power.

Another object of the invention is to proride a washing machine having a compartment in which water may be maintained at substantially ,a constant level, means connecting the lower portion of such compartment to the upper portion thereof, together with means in the nature of an injector to circulate such water.

Another object of the invention is to prov. vide in a washing machine automatic feeding means to periodically supply measured quantities of soap or the like thereto.

A further object of the invention is to provide in a washing machine generally improved mechanical structure.

. Other objects and advantages will appear in the following description and in the illustrative embodiment of theinvention in the accompanying drawings, in which- 'Fig. 1 is a front-elevational view of a washing machine embodying the invention;

Referring to these drawings: A represents the casing of the machine which affords a chamber or washing compartment C. A door D hinged along its lower edge at h affords access to compartment C and is mov- .able to a horizontal position, as shown by dotted lines in Fig. '2, to provide a shelf upon which the articles to be washed may be placed. Such articles are preferably" placed in a wire mesh tray or basket B (Fig. supported by a plurality of cross rods 1- on door at (Figs. 2 and 41), and th tray, after the articles have been assembled therein, may be pushed along the shelf forming door D into the compartment C. In the latter, and suitably supported from casing A as indicated, are two spaced angle iron tracks t along which the tray may be slid and thereafter supported for the -The washing and rinsing operations are accomplished by the use of the same twosets of nozzles, one set being located above and the other below the basket B. As shown in Fig. 4, a header pipe 11 is-supported along the rear wall of easing A and this pipe supplies all the nozzles of the lower set. There is a corresponding and similarly located header pipe 12 located above the basket B,

as indicated in dotted lines in Fig. 1. Connected to the header pipe 11 at suitable intervals therealong, and extending forwardly toward the front of casing A, are a plurality of nozzle pipes 13, the outer ends of which terminate closely adjacent the front wall of the casing and are capped, as indicated at 14. Removably connected to each pipe 13 at regularly spaced intervals therealong are a series of nozzles 15 which project upwardly therefrom. One of these nozzles is shown in Figs. 5 and 6 and. as indirate streams, which streams are directed at many different angles. The several nozzles are also spaced uniformly so as to cover the entire area of the compartment C beneath, or above. the basket B. The result is that there is no part of the basket B which is not reached by the streams from the nozzles and, in fact, the streams from adjacent noz zles overlap and the streams from one crisscross those from the next to insure that all parts of the basket B will be reached from many and widely varying angles. This arrangement is important as providing for effective washing and rinsing operations.

The header member 11 is connected, as shown in Fig. 4, to a pipe 19 which extends vertically along and outside the rear wall of casing A to positions above and below the compartment. C- (see, Fig. 1). At its upper end pipe 19 is connected to a check valve 20 (see also Fig. 9), and such valve permits water to enter, but not to leave the upper end of pipe 19. At its lower end pipe 19 is connected to a check valve 21 which likewise permits water to enter, but not to leave the lower end of the pipe and which may be of the same construction as the valve 20. The upper header pipe 12 is connected to pipe 19, in a manner similar to that in which header pipe .ll is connected, and at a point between the checkyalves. Through the check valve 21 the washing water is forced upwardly through pipe 19 to both sets of nozzles, and through the check valve 20 the rinsing water is forced downwardly through the pipe 19 to the same two sets of nozzles. There are separate, alternately operable, and automatically controlled means to deliver washing and rinsing Water to the pipe 19, as will appear.

The water, used forboth washing and rinsing, enters through a pipe 22 which is adapted for connection to a suitable supply of hot water. Pipe 22 extends downwardly and is connected through the bottom wall of casing A to the compartment C. A thermometer T may be provided in pipe 22, if desired. and a valve 23 is interposed in pipe 22 and normally is closed. but can be opened to fill the lower part of compartment C, when necessaryor desired. An overflow pipe'24, adapted for connection through pipe 25 to the sewer or other drain, provides for a substantially constant. level of water in compartment C. In the lower part of the latter is a screened outlet 26 through which water from compartment C may flow into an elbow-shaped casing 27, which is connected, as indicated, to the check valve 21. Mounted in casing 27, and in line with its outlet end, is a nozzle 28 and such nozzle is connected by a pipe 29 to a valve 30, (Fig. 3) mounted on the upper wall of casingA. The members 27 and 28 constitute an injector, operable by using water admitted into pipe 29 by valve 30 to force water, taken from the lower part of compartment C, through valve 21 and upwardly through pipe 19 to the nozzles 15. A regulating valve 31 is interposed in pipe 29 to control the flow to the injector 28 and to vary such flow as is necessary or desired.

The main inlet pipe 22, is connected above wardly through pipe 19 to both sets of nozzles.

Both valves 30 and 33 are similar and are of the well-known type which automatically close. As shown in detail in Fig. 8,

the valve 30 is formed with two chambers a and b separated by a partition 0 having an openingextending therethrough in which a valve (Z is normally seated. The valve (Z is carried at the lower end of a valve stem e which extends through a stutling box in the valve casing and is adapted to be lifted to open the valve. The valve is rendered selfclosing by means of a spring 7' which surrounds the valve stem between the valve and the inside of the valve casing. The valve 33 may be opened by a lever 36 which is pivoted at 37 to a bracket on casing A and is connected intermediate its ends to the stem of the valve. The valve 30 may be opened bv a similarly mounted lever 38 (Fig. The free ends of levers 36 and 38 rest upon cams 39 and 40, respectively, which cams are fixed upon a shaft 41. suitably sup )ortcd from the top wall of easing A. .onsequently, on rotation of shaft 41 in a clockwise direction (as viewed in Fig. 1) the lever 38 will be first lifted by cam 40 to open valve 30 and thereby permit the washing water to be forced into compartment (7 by the injector device described. Eventually, cam 40 will allow lever 38 to drop and close valve 30. About this time, preferably shortly before. cam 39 raises lever 36 and opens valve 33 to admit rinsing water into compartment C. The two valves 30 and 33 have a function in controlling the rotation of shaft 41 and it istherefore desired to have the latter open slightly before the former closes, merely to insure continued rotation of the shaft. Thetwo valves are,

From

pipes

29 and 35, two smaller pipes 45 and 46 extend upwardly and connect with a horizontal pipe-47 which in turn delivers j into a pipe 48 extending downwardly and tangentially into casing 43. A regulating valve 49 is preferably provided in pipe 48 to contr'ol'the flow ofwater to the water motor and thus the speed of the latter.

' vTo start the water motor, an operating crank 50 is loosely mounted on shaft 41 and is provided with a clutch element 51 which,

when crank 50 .is' moved inwardly, may enage a mating clutch element 52 fixed'on shaft 41 (Fig. 3). A spring 53 (Fig. 1) tends ,to hold crank 50 in the illustrated position, wherein it abuts a stop 54 on casing 43.

ing to rest in the illustrated position. Thus,

each of the valves 30 and 33 areautomati cally held open-for a predetermined interval.

Associated-with the casing A is an automatic means to supply measured quantities of soap or the like to the water in the lower part of easing A. Such means includes a container 58 for soap outlet end of container 58 communicates with a cylindrical casing 59 in which is rotatably mounted a pocketed feed wheel 60, 'which'is arranged to turn step by step and to carry measured charges of soap from the container and deliver them into and through a passage 61 into casing A. On one end of the shaft 62 of wheel is a toothed wheel 63 (Fig. 2) and above the latter is a crank pin 64, carried by a disk 65 fixed on the deshown by The crank 50 may, however, be moved downwardly against the tension of 53 until it abuts a second stop 55;

or the like, preferably in either powdered or liquid form. The

scribed shaft '41. The arrangement is such l that on each revolution of shaft 41, the pin 64 will engage the toothed h l 63 and whereby the feed wheel 60 is turned to empty one its pockets into the The actuation of the wheel 63 turn it one step,

The operation will largely appear, from the foregoing description and need only be briefly summarized. Having a suitable sup -ply of water, at the proper temperature as thermometer T, the lowerpart of easing A opening the valve 23. Having filled the casing to'the desired level and closed valve 23 and having placed the basket B within compartment 0 and closed door D, the operator pushes crank 50 inwardly to engage the clutch elements5l and 52 and then turns it clockwise until it strikes the stop 55. This is' filled to the desired level by effects an opening of valve 30 and admits water to'the rotor 42, which controls the timing cams 39 and 40. The cam 40 first opcrates and holds valve 30 open for apredetermined interval during which water, a large part of which is taken from the base of compartment C and therefore has soap or the like therein, is forced through the many nozzles to effectively washthe articles in basket 13. At or about the time that .valve 30 automatically closes, cam 39 comes into play and opens valve33 to admit clean hot water to the nozzles for the rinsing'function. The rinsing continues for a predetermined interval which is terminated by the automatic closing of valve 33. I v
