WASHING MACHINE.

Application filed August 28, 1920. Seried No. 406,623.

To all 11:71 am i1: may concern:

Be it known that I. Ror AfReniNuo, a

particular regard to machinesof this type 15 designed for domestic use. It willbe understood, however, that such improvements are not necessarily limited to any particular size of machine, and that they may be used in connection with other machinesinvolving a similar mode of operation. One object of the invention is to provide amachine of the type in question, in which the water or other cleansing liquid may becaused to pass and repass through the articles being washed. A

further object is to adapt the machine for I the reception of a varying quantity of such articles and still secure thorough cleansing action; still another object is to render the machine simple in construction and easy to operate, a minimum amount of power being requisite. r

To the accomplishment of the foregoing and related ends, the invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims, the annexed drawing and the following description setting forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but 40 the principle of the invention may be used.'

In said annexed drawing Fig. 1 is a central vertical section of a washing machine embodying my present improvements; Fig. 2 is a transverse section of such machine taken on the plane-indi cated by the line 2-2, Fig. 1; Fig- 3 is a broken perspective view of a portion of the container in which the articles being washed are placed; Fig. 4 is a. similar broken per- .spective view of a portion of a retainingv member that co-operates with said container; and Fig. 5 is, a broken side elevation 1 of the motor and driving connections whereby the machine is operated.

one of various mechanical forms in which The tub or main container 1 is of substantial construction and of general cylindrical form, with its axis vertical. Said tub is preferably of greater height than diameter, and while shown with its upper end open, a removable cover may be provided if desired, as also suitable connections (not shown) for supplying liquid to its interior,

and for draining such liquid therefrom, The tub rests on a suitable frame 2, which also serves to support the motor 3, and the shaft 4;, which is driven by said motor, is in turn connected with the movable part of the machine, as-will be presently explained.

Supportedv within the tub or container 1,

by means of rods 6, vertically movable" in suitable bearings 7, is an open-ended container or basket 8. The side wall of this basket is preferably made of sheet nietal bent to cylindrical form and fitting snugly within the tub, said wall beingformed with outwardly directed flanges to insureth s, and beingalso formed with an inwardly directed flange 9 adapted to receive and sup-- port a circular screen 10. The latter may be lifted out of the basket when it is desired to gain access to the bottom of the tub for the purpose of scrubbing the latter. and while such screen is preferably made of wire, woven to form a net, it may consist of a perforated sheet metal plate or other equivalent coi'istruction. At spaced intervals about its circumference, the side wall of the basket is provided with inwardly directed vertically extending corrugations 12' shown in detail in Fig. 3, such corrugations being cut away at corresponding distances from the bottom of the container to leave recesses or slots 13. A second screen 14-, similar to bottom member 10, is provided, said screen being likewise fitted to the interior of the basket, and. having a series of recesses '15 in its circum ference corresponding in. location with the corrugations 12 (see Fig. 4). Accordingly, by aligning such recesses 15 with the corrugations 12, this screen 14 may be dropped in the basket.- to any desired height above said bottom screen 10, and their, upon slightly rotating the same so as to bring the recesses out of alignment with the corrugations, the screen will be firmly held atthc, selected elevation.

I may also" employ more-than one such screen 14, two being shown in Fig. 1 by way of illustration, so as to divide up the basket bent outwardly to" enter suitable hearingsin .the corresponding ends of the bars 17. Intel-posed between the bearings 7 in which the rods (5 are slidably held, as previously described, and adjustable collars 19 screwthreadedly engaged on said rods, are compression springs 20 which are designed to partially support the load of the basket and oflthe articles carried therein.

The operation of the machine may now be briefly set forth. The articles to be washed are evenly distributed in the basket between the screen 10 and the screen 14, and the latter thereupon secured in place at the proper level to hold such articles in desired more or less compact form; or where two or more screens 14 are employed the proper portion of such articles are placed between these, as we'll. Thereupon the tub I is filled with Water or other cleansing liquid to the proper height, and the basket is" then reciprocated up and down by rotating the shaft 4 through the medium of motor 3, the upward movement being assisted by the resiliency of springs 20. Due to the fact that the side wall of the basket fits closely the interior of the tub, the water in'the latter is caused to pass and repass through the articles held in said basket between the lower screen 10 and the upper screen 14. The rate of reciprocation may of course be varied to suit the character of the articles and the rate at which it is desired to force such cleansing liquid through such articles.

Other modes of applying the principle of my invention may be employed'instead of theone explained, change being made as regards the mechanism herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

basket when it I therefore particularly point out and distinctly claim as my invention 1. In a machineofthe character described,

the combination of a-cylindrical tub supported with axis vertical; anopen-ended 0y ialign with the corrugations in said basket,

whereby upon rotation said screen may be secured ina selected corrugations.

2. In a machine of the character described, the combination of a' cylindrical tub supported with axis vertical; an open-ended cylindrical basket within said tub for containseries of slots in such ing the articles to be cleansed; perforatedclosuresfor the top and bottom of said basket; rods vertically reciprocably secured to the sides of said tub and supporting said basket; resilient means associated with said rods; adjustable means co-acting with said resilient means to act as a buffer for said approaches its downward limit of motion. 7 i

3. In a machine of thecharacter described, the combination of a cylindrical tub supported with axis vertical; an open-ended cylindrical basket within said'tub for containing the articles tobe cleansed; perforated closures for the top and bottom of said hasket; vertical hearings attached tothe upper edge of said tub; rods vertically reciprocable in said bearings and attached attheir lower ends to said basket for supporting and moving the latter; adjustable collars on said rods above said bearings; and compression springs-interposed between said collars.
