Specification of Letters Patent.

Patented June a, 1900.

Application filed October 16, 1906. Serial No. 389,033.

To all whom it may concern:

Be it known that I, Gnonon A. Pos'r, a citizen of the United States, and resident of Chicago, county of Cook, and State of Illinois, ave invented certain new and useful- Improvements in Washing Machines, of which the following is a specification and which are illustrated in the accompanying drawings, forming a art thereof. The invention re ates to machines fo washing clothing, and particularly to those of that type in which a receptacle adapted to be rap d y revolved is rovlded for the articles to be washed, an .a cleansing fluid is caused to permeate the contents of the reoepltacle by centrifugal force.

- he mvention contemplates a basin for containing the cleansing fluid, a clothes receptacle mounted for rotation within the basin and having ,a foraminous peripheral wall, and means for raisin the cleansing fluid from the floor of the basin to the interior of the receptacle. v

A feature of the invention provides for removing the fluid contents of the basin in order that the device may also be employed in the usual way as a centrifugal drying machine.

-from a base or floor 1 the shell 10 takes the form of a basin having The object of the invention is to provide means whereby clothing may be washed,

rinsed, blued and dried in a single machine without being handled between such operations.

is a central vertica section showing a machine constructed according to' the invention; Fig. 2 is a plan view, artly broken awa of the same machine; 1g. 3 is a sectional detail taken on the line 3-3 of Fig. 2; Fig. 4 is a sectional view on the line 4 4 of Fig. 1.

A cylindrical shell 10 is rovided for the operative parts of the machlne, andis prefera ly carried by standards, as 11, 11, rising plate 12. As shown,

av floor 13 which is downwardly incline toward its center and is provided with valved pipes, as 14, 15, for the introduction of the various fluids employed in treating the articles. to be cleansed, andwith a valved drain-opening 16. The side walls of the shell or basin are flanged inwardly at the top, as indicated at 17, and aremovable cover 18 is applied thereto. 1

A clothes rece tacle 19 is rotatablymodnted within the asin, being preferably se- In the accompanying drawings, Figure 1' cured to a shaft 20 which is stepped in the base plate at 21 and extends u wardly through the floor of the basin. As s own, a roller bearin 22 is provided for the shaft in the floor of tile basin, and a packing gland 23 is ap lied to one end of the bearing to prevent eakage. The side walls of the receptacle 19 are freely perforated, asindicated at 25, to permit the escape of water by centrifugal force, and the upper mar ins of its walls are flanged inwardly, as indicated at 26, to revent the contents of the race tacle from eing thrown over its sides. or driving the rece tacle a belt pulley 24 is preferably mounte on the shaft 20 below the basin.

Provision is made for the admission of water from the basin 10 to the receptacle 19 adjacent its axis of rotation. For this purpose there is shown a plurality of openings 27 formed in its floor, and for each opening there is preferably a lip 28 which projects downwardly at an angle from one ofthe side edges of the opening to form a chute for directing water from the basin through the openin to the interior of the receptacle. Prefera 1y, also, a stand-pipe 29 rises from the floor of the basin at its center for delivering water to the interior of the clothes receptacle 19. As shown, it is provided at its foot with a plurality of intake openings 30, and the floor of the receptacle 19 1s socketed, as indicated at 31 to fit over the head of the pipe and to provide a nozzle for the discharge of water from the pipe to the interior of the receptacle. This nozzle preferably comprises a plurality of pipes 32 which extend radially outwar and upward from the walls of the socket 31 and have their outer ends united by arin 33, which has a plurality of circumferential 'y arranged eduction ports 34.

An Archimedean screw 35 is mounted within the stand pipe 29 for raising water from the floor of the basin to the discharge openings 34 of the nozzle. As shown it is formed u on a sleeve 36 which incloscs a portion of t e shaft 20, and is firmly secured thereto by means of a cotter pin 37.

To arrest the circumferential movement of the water delivered from the side walls of the rotating receptacle 19, and to direct it toward the, center of the basin 10, a plurality of baffles 38 are formed. on 'the side walls of the basin. As shown tlfese liafllcs are continued along the floor of the basin to the stand pipe 29, and each joins the walls of. the stand pipe at the side of one of the openin 30 at its foot. Preferably that parteach of the baffles which extends along the floor of the basin is formed in a curve inclined to a radius of the basin, as indicated at 39, Fig. 2, and is provided with 19, while still ry, and the machine given a few revolutions at a high speed before any of the cleansing water is introduced in order that the clothing may become compacted against the side walls of the receptacle 19 Without tangling or tearing. Water for cleansing, rinsing and bluing the articles will then be introduced in succession through the valved pi es 14, 15, a suificient quantity being prefera ly employed in each case to fill the basin 10 to a depth adapted to cover the floor of the receptacle 19 when the ma- .is. still in motion.

chine is at rest. 'By means of the screw 35 Within the stand pipe 29 and the inclined lips 28, water will be delivered to the interior of the receptacle 19 when it is rapidly revolved, through the openings 34 and .27, respectively, and will be thrown by centrifuf gal force upon the clothin compacted against the peripheral wall of t e receptacle} On passing through the clothing, it will be delivered to the side walls of the basin through the openings 25 in the walls of the race tacle 19, and it will then be directed by the affles 38 to the center of the basin. From this point it willbe again drawn into. the receptacle by the Archimedean screw 35, and a continuous circulation of the fluid contents of the basin is thus maintained. After one or more of the washing operations have been completed-in the manner described, the clothing contained Within the receptacle 19 may"be thoroughly dried by opening the valve of the drain-pi e 16 while the machine he excess water held by the clothing will'then be thrown by centrifugal force a ainst the side walls of the basin from whic it may escape through the drain-pipe. 1;
