GEORGE Bunsen KELLY, or CHARLES CITY, IOWA.

Application filed July 30,

My invention relates to improvements in washing machines, and the ob ect of my improvement is to furnish a removable water circulating device for and c( mloinat1on. with the tub of a washing Inach1ne, and 1n. which the tub is modified 1n'1ts construction to fully cooperate therewith, in the forced lavation of clothes in the tub without injury thereto and with a maximum effectiveness and rapidity of operation. N

This" object I have accomplished by the means. which are hereinafter described and claimed, and which are illustrated in the accompanying drawings, in which Flg: 1- 1s a central vertical section of a washing machine constructed according to my invention and with certain elements thereof in elevation. Fig. 2 is a fragmental top plan of the bottom part of the tub, showing the detachable apertured segment thereof. for discharging "the liquid contents of the tub. Fig. 3 is a horizontal section of the motor and propeller casing of the machine taken on thebroken line 33 of said Fig.1 looking downwardly. v My invention is not restricted to the precise construction and arrangement of parts herein shown and described, nor to the various details thereof, as the same may be modified or rearranged in various particulars without departing from the spirit and scope of my invention, one practical embodiment of which has been herein illustrated and described'without attempting to show all of the various forms andmodifications in which my invention might be embodied.

Referring first to said Fig. 1, the numeral 1 denotes a cup-shaped tub with open top closed by a removable closure 8, said tub 1 including an integral lateral motor and propeller casing 9 to receive the inner casing 26 of vertically elongated cylindrical form with closed end heads, the upper head being centrally 'apertured to receive the vertical; motor-shaft 34. The bottom part of the outer "1 casing 9 has a step-bearing cup 25in which is removably seated another bearing cup 33 .in line with and. stepping the lower end of said shaft 34. The open upper end ofthe outer casing part 9 may be closed by a removable closure member 10 aperture'd at 23' to receive therethrough the upper part'of the 3 rotary shaft 34,'a pinion 36 being'mounted thereon for use as a driving element in the H gearing combination of a wringer not shown.

The outer cylindrical casing 9 has in; its

WASHING MAGHIN E.

outer wall at the lower end thereof an outletport 42 covered by a diminished nipple 43 terminally exteriorly threaded to receive a threaded cap 44, and the latter may be removed for substitution of a hose coupling not shown, when it is desired to evacuate the liquid contents of the tub 1 after washing clothes. This port 42 and nipple 43 may preferably be positioned circumferentially nearer a port 41 of the casing 9 opposite, but is shown opposite the of illustration merely.

Onthesame side of the casing 9 as the lower port 41 and vertically above the latter is an inlet-port 20 which is separated from the port 41 by an interposed block 14 seated in a horizontal medial hollow 15 of the tub base with parallel side walls. movable merely as an expedient in the casting of the tub in a single piece, the block being separately cast and then mounted in the lower part of said hollow 15 to fit and close the latter. Said hollow 15 opens at the top screws 19 and being a flush portion of the port 41 for clearness This block is re- 1 s 1nner surface "of the tub. This plate 17 has numerous evenly distributed small discharge holes 18 in communication between the interior of the tub andsaid hollow 15 and the port 20 of said casing part9. In the bottom part of the tub body 11 is formed a radial horizontal passage 13 in communication with the port 41 of the inner casing 26 and casing 9. At its inner end the passage 13 is continued curvingly upwardly at 12' to open upwardly centrally intoihe bottom of the tub 1. The tub 1 may have an integral de ending and diminished central stem 2 wit a diminished end boss 4, the boss fitting into a cylindrical hollow 5 central in the top part of a widened base body 7. A solid shaft 3 is fixed in a central seat in the stem 2 to depend into a cylindrical beating hollow 6 in the base 7, so that the tub 1 may be rotated on the base. -The shaft 3'may, if desired, be fixed in the hollow 6 and loose in the central hollow of the stem 2.

The inner casing 26 has an upper cylindrical compartment in which is mounted an electric motor,,35 which drives the rotary v shaft the. shaftv depending centrall through a diminished part of the casing wit port 20, he hollow 15 and the holes 18 leading from the interior of the tub 1.

Within the lower casing part 32 and occupying its upper end an annular body 38 is centrally positioned spaced about the shaft 34 to provide an annular conical port 39 therethrough, and this body 38 is fixed upon a sleeve mounted fixedly upon the shaft 34 and depending to the bottom of the compartment 32 and carrying a number of propeller vanes 40 which are cyli-ndrically concaved vertically in the direction of rotation as indicated by the arrow. The inner casing 26 is preferably constructed with like fitted longitudinal halves, the approximated edges preferably having a sealing gasket 27 between them, and

the edges of these halves may be fastened to gether by any suitable means, such as pins inserted in registering holes 28 inserted from outside grooves. The annular body 38 serves as a fly-wheel upon said shaft 34.

The motor rotates the shaft 34 With its fly-wheel 38 and concave vanes 40'. Suction induced by the rapidly rotating vanes in the compartment 32'causes an indraft of water from the tub 1 into the compartment 32 by way of the small holes 18, hollow 15, port 20, apertures 31, fly-wheel hollow 39, and the vanes propel the water out of the inner casin compartment 32 by way of the port 41, and passage 13-12 centrally upward like a jet through the tub 1 and to penetrate the textiles in the tub, opening out their folds, and'in the eddying currents set up in and because of the cuping of the tub, the articles are carried around frictionally contacting with each other and the tub wall, until cleansed. This forced circulation of liquid is maintained a suitable length of time, and then the liquid may be evacuated from the machine, by coupling a hose to the threaded nipple 43, and

. thenby means of ahandled stem 24 fixed on the top of the casing 26 eccentrically, said stem traversing an arcuate slot in the cover part 10, partially rotating the casing 26 to bring its port 41 into communication with the port 42. The still rotating vanes 40 then drive the liquid in the tub by wayof said nipple, the passage 1312 being closed except for a slight interspace allowing complete issuance of the liquid in the said passage 1312.

When the cover part 10 is removed, the in ner casing 26 may be lifted out from the outer casing 9, to permit cleansing of the machine or the mechanisms in the casing 26, or for their repair. The tub 1 affords complete clearance, and amaximum filling capacity, and has no protuberances likely to injure the lightest fabrics.
