To all whom it may cone-em Be it known that LAN'roN C. SoHMnLznR,

born in Hungary of Hungarian parents, now believing myself to be a citizen of that 5 country, and having formally declared my intentions of becoming a citizen of the United States of America, in conformance with the United States immigration laws, and now residing at Springfield, in the l county of Hampden and State of Massachusetts, United States of America, have invented certain new and useful Improvements in Washing Machines, of which the following is a specification. v

This invention relates to Washing machines, and more particularly 'to machines for washing and rinsing or sterilizing drinking glasses, dishes and like articles.

An object of the invention is to provide, 2 in a washing machine, 'mechanism which may be manually set in motion to-start the washing operation and which thereafter automatically stops such operation and then starts and stops the rinsing operation, there- 2 by automatically limiting the duration of each operation to predetermined intervals. Another ob'ect of the invention is to provide in a was ing machine, pumping means for the washing-and rinsing water, of a motor to drive said means, the motor being a water motor and characterized in that it uses the water subsequently forced by the pumping means. Thus, no extra costfor motive power is necessary.

Another object of the invention is to provide in combination with a single means for supplying water to the machine, a feeding device to supply soap or the like to the water in said means during a predetermined indo terval and to later cut off the supply of soap, so that both washing and rinsing water may be fed through the same means.

A further object of the invention is to provide in a washing machine generally im- 5 proved mechanical structure.

Other objects and advantages will appear in the following description andin the illustrative embodiment of the invention in the accompanying drawings, in which Fi 1 is a front elevational view of a washlng machine embodying the invention;

Fig. 2 is a side elevational view thereof,

partly in section;

eferring to these drawings; the machine includes a casing A su ported by a suitable.

frame F. Casing A a ords a washing compartment C, access to which is had by the opening of a door D. The latter is hinged along its lower edge and' opens to a horizontal position,'as indicated by dotted lines in Fig. 2, in which position the door forms a shelf to receive the basket B of wire mesh, A

within which the articles to be washed are placed. The-basket B is. arranged between and supported by a pair of lazy-tongs 10, being fastened to the outer end upright links 11 thereof and being supported b the lower series of pivot pins 12. Each azytong 10 is secured at its other end to the rear wall of casing A. Consequently, the basket B is supported for substantially horizontal sliding movement and may readily be pulled outwardly from the compartment G into an accessible position in which it overlies door D. The basket B, however, is, obviously,

held against removal from the m'achine.

- Within the compartment C are a plurality I of nozzles 13 arrangedin upper and lower sets, so asto direct water from above and below-the basket B. The nozzles 13 may be of anysuitable type and are connnectedat I slpaced intervals to and along pipes 14. here are, of course, a plurality of pipes 14 extending across the casing, but, inasmuch as the present invention. is not primarily concerned with the construction and arrangement of the nozzles, detailed description and illustration'thereof is unnecessary I to an understanding of the invention.'-'It will suffice to state that there are a large numher of nozzles arranged in upper and lower sets and that both sets are supplied with water from a common pipe 15, which extends downwardly below casing A for connection to mechanism arranged therebelow and supublv mounted and this screw is driven from the shaft 19 of rotor a" by a chain 20 and suitable sprockets. As shown in Fig. 1, the screw shaft 18" is driven at much higher speed than the rotor 1' and thus the water,

after leaving the water motor, is increased in velocity before being delivered into the described pipe 15.

The outlet end of casing 17 is not, however, connected directly to pipe 15. Rather, there is interposed between these'elements a casing 21, which is best shown in Fig. 3. The lower part of casing 21 afi'ords communication at all times between the casing 17 and pipe 15. In the upper part of casing '21, however, there is provided a tubular basket 22 of wire mesh, within which soap, preferably in cake form, may be placed, as indicatedat s. The basket 22 has a solid bottom plate 23, which is formed to coa'ct with parts of casing 21 to act as a valve and close ed the upper from the lower part of the casing. That is, with the parts positioned, as shown in Fig. 3, water passing from easing 17 to pipe 15 will not acquire any soap, but when basket 22 is lowered into the lower part of the casing the water from casing 17 will necessarily pass through basket 22 and dissolve some of the soap .9, which will then be carried in suspension into and through the pipe 15 to the nozzles 13.. The basket 22 is supported by a rod 24 which is slidably mounted'in casing 21 and emerges from the upper end thereof through a suitable stufling box, indicated conventionally at 25. Rod 24 has a collar 26 on its lower end and, between such collar and' the valve plate 23, is interposed a spring 27. Thus, the movement of rod 24, which is of fixed degree as will appear, may be made greater than that necessary to seat the valve plate 23, the excess movement being permitted by the interposed spring 27. This arrangement insures that the valve plate 23 will always seat even after an appreciable degree of wear has occurred between the coacting parts.

The inlet pipe 16 is connected to a valve- .28 and from this valve a main inlet pipe 29 extends to a suitable supply of hot water (not shown) Valve 28 is of the well-known self-closing type and has been illustrated merely in conventional form. The valve in cludes a stem 30 ('Fig. 6) carrying on its upper end an eccentric strap 31. ,An eccentric 32 is mounted within this strap and fixed to a shaft 33 mounted in and between spaced lugs 34. A long lever 35 hasa forked end to straddle lugs 34 and the shaft 33 is fixed in 'such forked end. Therefore, an upward swinging movement of lever 35 will turn eccentric 32 and open the valve. ofthe lever, when released, combined with the usual self-closing spring in the valve will insure an automatic closing of the latter.

The lever 35 is adapted to engage in "a radialnotch 36 (Fig. 5) formed in a disk 37 and when in such notch, the valve 28 is closed. The disk 37 is rotated from the shaft 19 through the intermediary of a gear redueing mechanism which is represented conventionally at R in Fig. 2. The arrangement is such that disk 37 revolves at very slow speed and makes one revolution only duringthe interval necessary to perform both the washing and the rinsing operation. This interval may be gauged as desired by the mechanism R and may, for example, be one minute or .some such relatively small interval. In one face of disk 37 there is provided a cam path 38 which is arranged to actuate a lever39 pivoted intermediate its ends at 40 and connected at its free end to the described stem 24 of the soap container. vThe cam path 38 is so designed as to hold stem 24 in lifted The weight position when disk 37 is at rest and, shortly after the disk revolves, to lower stem 24 and hold it lowered fora predetermined interval and thereafter to raise the stem before the one revolution of disk 37 is completed and hold it in "raised position-for a redetermined interval.

' In operation, after the articles to be washed have been placed in basket B and the basket pushed into casing A and door D closed, the operator merely lifts lever 35. This simultaneously opens valve 28 and releases disk 37 for rotation. Upon the.open-' ing of valve 28, water immediately passes to motor M and the motor causes disk 37 to revolve. A release of lever 35 thenallows lever 35 to drop upon the periphery of disk 37, which prevents valve 28 from closing. Then the water used by gnotor M is. discharged in casing 17 .and then propelled at increased speed by screw 18. The ,water is discharged-into pipe 15' through the casing 21 and, the cam 38 having lowered the soap containing basket 22, the water, being hot, dissolves some soap and carries it in suspension into the compartment C. After the elapse of a predetermined time, the cam 38 raises stem 24 until valve plate 23 seats and thereafter clean hot water is forced through. the nozzles 13 into compartment Cto efiect' ing I ter dropping into the notch to prevent fu'rther rotation of disk. 37 and at the same time closing valve 28. v
