COMBINED WASHING AND RINSING MACHINE Filed Dec. 4, 1957 INVENTOR ATTORNEYS,

Patented June 6, 1939 y UNITED STATES PATENT OFFICE COMBINED WASHING AND amsmc momma I Louis De Marco, Cleveland, Ohio Application December 4, 1937. Serial No. 178,116 6 Claims. (01. oa -s3) parts shown in the drawing hereof, wherein Fig.

1 represents a central vertical sectional view through the upper portion of a washing machine embodying my invention and Fig. 2. a' plan view of the machine shown in Fig. 1.

Describing first the construction shown in Figs. 1 and 2, I denotes the tub, the same having a bottom 2 and a supporting base 3, which may be of any standard construction. 4 denotes a hollow standard which is secured at its lower end to the bottom 2 as by means of a nut5, there being a washer 8 interposed between the said nut and the portion of the bottom surrounding'an opening 12a therethrough. A

1 denotes the housing for the mechanism which'drives the shaft 8, the latter having a squared upper end 9 received within a Cortespondingly shaped socket I! in the top of the rotor body III, the said'body being provided with the usual blades ll.- l2 denotes a bearing which is interposed between the upper portion of the shaft and the standard 4, and I3 a similar bearing which is interposed between the standard and the lower portion of the rotor body. V

The construction and arrangement of the foregoing parts are those used in a well-known type of standard washing machine and need no further description. v r

In order to convert the machine thus shown and described into an efiective rinsing'machine, 40 I have providedthe following construction: l4 denotes a cover having a central opening it by means of which it may be set down within the tub, below the top of the rotor body. This cover is provided with openings IQ for the passage of the rinsing water and with a gasket l'l set within an annular channel I! formed within the outer periphery of the cover, thereby to insure a substantially leak-proof engagement between the cover and the inner wall of the tub and to serve as a bumper to prevent marring the said wall.

The cover issupported in proper relation below the top of the standard 4 by means of locking means carried by ribs l9 preterably integral with the cover and extending upwardly and outward- 1y from the central opening l5. As shown, these ribs comprise each a widened top connected intermediate its inner and outer ends to the body of the cover by a-web 24. The webs of the ribs may be considerably shorter than the tops there of, thereby to provide large openings 2| through which the water flowing through the openings I may be delivered freely to the outlet. Pivoted to the upper ends of the ribs I! are the swinging supports 22 for the latches .22, the latches being pivoted to the lower ends of the members 22 and adapted to engage beneath an outturned flange 24 at the top of the tub. v

25 denotes a waste spout extending along the outer side of the tub and having its upper widened end 25* located immediately above the cover I4. I

26 denotes a valve body which is secured to the bottom of the tub and the portion of the side adjacent thereto, as by rivets 2". 21 denotes a rotary plugmounted within the valve body and The operation of the combined washing andrinsing machine thus far described will be readily understood. The water for washing the.

clothes or other articles may be placed in the tub in the usual manner, or supplied through the pipe 29 which may, it desired, be connected with both the hot and cold water pipes of the house. When the tub is filled for washing purposes, the valve 21 will be in its cut-oi! position. After the tub has been filled, the soap will be added to the water therein, and the rotor II- will be operated in the usual manner to agitate the articles in the tubl At the end of the washing operation, the valve 21 will be turned so as to drain the water from the tub, after which it will be turned to the position shown in full lines in Fig. 1, and water from the pipe 29 will be supplied to the tub while the rotor is operating. This will enable water to pass in contact with and through the articles that have been washed while the latter are being agitated by the rotor; and the soap and any sedi-' ment that may remain in these articles will be the openings in the cover l4 and being delivered through the waste pipe 25. The openings it are preferably upwardly tapered or frusto conical, as shown, whereby to prevent the collection of soap about the edges of the openings thereby to ia-' cilitate the discharge of the soapy water therethrough.

The cover is provided with radially extending ribs I l M projecting downwardly from th lower surface thereof. These ribs serve the double function of preventing the articles from being forced into engagement with the bottom of the cover and clogging the opening it as well as cooperating with the rotor in effecting speedy removal of soap and sediment from! the said article. o

It will benoted that the cover and the 'overflow outlet 25 are located below the top of the standard it. This enables the rinsing operation to be performed without the liability of the water rising to and overflowing the top of the standard and being delivered therethrough into the'mechanism which operates the rotor.

The embodiment of my invention just discussed is applicable to existing washing machines, without any material alteration in the tubs thereof.

It will now be clear that I have provided a combined washing and rinsing machine which will accomplish the objects of the invention as hereinbefore stated.

Having thus described my invention, what I claim is? 1. A combined washing and rinsing machine comprising a tub, a central standard projecting upwardly from the central portion of the bottom of said tub, a rotor having a body surrounding the said standard and extending thereabove, a shaft mounted within the standard and extending through and beyond the upper end thereof and connected with the rotor body, means for rotating the said shaft, connections 'for supplying water under pressure to the lower portion of the said tub, there being an overflow for the water so supplied located below the top of the said standard, and a perforated cover supported by said tub and disposed below the overflow and having a central opening for the reception of the upper portion of the rotor body. I

2. In the combined washing and rinsing machine recited in claim 1, the cover having a gasket in the outer peripheryl thereof engaging the inner wall of the tub.

3. In the combination recited in claim 1, the

cover being provided with ribs extending upwardly and outwardly irom the central opening thereof, the upper end of the tub being provided with an outwardly projecting flange, and locking devices carried by the upper and outer ends of the said ribs and adapted to be removably engaged beneath the said flange.

4. A combined washing and rinsing machine comprising a tub having an overflow, a rotor provided with agltatingmeans and located within the said tub, a cover located below the said overflow and above the agitating means and having openings therethrough, means for operating the said rotor, and connections for supplying water under pressure to the lower portion of the said tub.

5. In the combined washing and rinsing machine recited in claim 4, the cover being provided with ribs projecting downwardly from the bottom thereof.

6. In the combined washing and rinsing machine recited in claim 1, the cover being provided with ribs proiectingdownwardly from the lower surface thereof.

LOUIS DE MARCO.
