This invention relates to washing machines, and more particularly to washin machines of the upright oscillator type, w erein the tub member is fashioned with a plu- 5 rality of blade or bafiie members upon the bottom thereof, the same being adapted to create a violent water action.

One of the objects of the invention is in the provision'of a washing machine of the upright oscillator type, the reciprocated tub member bein fashioned with a plurality of blade or ba e members upon the bottom thereof, the same being fashioned in a mannor to create a turbulent water action and therefore to cleanse the clothes content in a remarkably short time.

Another object is in the provision of a washing machine of the type wherein a tub member is reciprocated by power mechanism, said tub member being fashioned with wateraglitating means upon the bottom thereof, w

ereby the reciprocation of the tub and the action of the blades co-operate to cleanse the clothes in a very short t1me.

Still another object is in the provision of an upright tub member, power means for reciprocating same and blades disposed in the bottom of the tub, the side walls of the tub being free from obstruction, and a bafile disposed intermediate of the tub and projecting upwardly from the bottom thereof, providing not only a drain mechanism for the tub, but also means for preventing entangling of the clothes during the washing operation.

A further object is in the provision of an upright tub member, power means for reciprocating same, said tub member being provided with a plurality of spaced blade members upon the bottom thereof, said blades being raised a suflicient distance from the bottom to create a violent water action and being fashioned in a-manner to prevent excess wear upon the clothes during their violent reciprocation.

A still further object lies in the provision of an upright tub member, power means for reciprocating same, said tub member having bottom portion thereof said water-agitating water-agitating means,

.means being raised sufiiciently from the bottom thereof to create a violent water action,

and thereby cleanse the clothes content in a remarkably short time.

Other objects will appear in the following specification taken in coiihection with the annexed drawings, in which-- r Fig. 1 is a side elevation, partially in crosssection, showing in detail the arrangement of parts of the washin machine;

Referring to the drawings, in Fig. 1 there is shown in detail my upright oscillator type of washing machine, wherein a frame portion is shown at 10, securely attached, as at 11, to a supporting and housing portion 12, the same surrounding the tub and power means for the washer. Fixedly' attached to the lower endof the housing 12, as at13, are the plural leg portions 14, there being provided conventional connecting means 15 between same. A rim for the top of the housing 12 is shown at 16, the same being adapted to enclose a substantial part, of the upper end of the washing machine, or rather, the tub member thereof. Secured, as at 17, to the support or framing structure 10," is a bearing portion 18, of substantial length and disposed vertically, as may be clearly seen in Fig. 1. This elongated bearing portion 18 provides a.bearing surface both upon the inner and outer part of its up er surface.

secured in any suita therefor,

late 23 and the reach members lies in the efore mentioned friction elements 21. This frictional driving means provldes not onl 5 the driving connection between thetub and power means, but also a means for preventmg vibration during such reciprocation.

The tub is preferably constructed with the side wall curved inwardly as indicated at 32. Means for reciprocating the reach members 19 is provided in the pltman 26 the same being connected to the reach members at one end and having the pivotal connection 27 at its other end with a crank 28. Means for rotatin the crank 28 is rovided in a vert1- cal stu fixedly attached, as at 30, at its upper end. The vertical stub shaft is suitably supported in the supporting frame 10 at a point ad acent its upper end, and at ts bottom in a bearing 31 formed in a suitably arran ed gearin housing also attached to the housing 12 an sup ort 10. Means for rotating the vertical stu shaft is provided in the worm gear 33 and an adjacent worm 34. A conventional pulley 35 isattached to the dIlV- ing end of the worm and said pulley depends for its rotation upon a belt 35", the same emg driven by the conventional electric motor 36. The before mentioned downwardly pro ecting stem 25, which centers the tub 24, has an opening through its center portlon, as shown at 37, said portion openlng into a drain mechanism 38 adapted to carry off the water through the tub through the tube or outlet 39 to any point desired.

With respect to the tub 24, a plurality;J blades or bafiie's 40 are disposed upon he ottom of the tub, said blades being raised a substantial distance from the bottom thereof and adapted to create a violent disturbance of the water contents during reciprocation of the tub. These blades or bafiles operate in substantially the same manner as the blades upon a reci rocating disk in the well known t pe of was er, wherein the dolly ortion is disposed upon the bottom and the b des proect upwardly therefrom and are reciprocated in a manner to create a violent water action.

In the resent instance violent water action is not or y created by-the action of the u wardly' projectin b ades, but also by t e reciprocation of t e tub and it is apparent that the clothes content is continuously moved by the water action in a manner to yen shaft 29, to w ich said crank is cleanse same as well as to be agitated by the blades reci rocating with the tu The blad ends, as'shown at 41, to prevent excesslvc wear upon the clothes content during recip roc'ation. In Figs. 1 and 2 the blades are shown merging with the wall of the tub at positions approximately corres onding with the curved ortion 32, while t e inner ends are rounde and pro ect merely to a point adjacent the central portion of the tub. In other words, the outer extremities of the top ed es of said blades are curved upwardly the contiguous ortions of the side 0 the tub at positions he ow the lane of the upper end of said baflie mem r. The inner extremities of the top edges of the blades are extended downwardly to the bottom of the tub at positions spaced radially from said baiiie member. In these figures, a vertically disposed baflie or sleeve 42 either forms a part of, or is attached to, the bottom of the tub, the same operating to supportthe drain mechanism WhlCh comprises a drain plug or valve 43' adapted to seat in=a draina e aperture in the bottom of the tub, a vertical y disposed manually operated screw or lug member 45 attached to the upper end of member 44 and adapted, by manual movement to raise the dram plug from its seat and therefore permit the draining of the tub. Apertures 46 permit entrance of the water content in the tub to a 43". as. c

It might be said at this point that the baflie or sleeve 42 not only acts as a means for supporting the tub drain mechanism, but also as a centrally disposed member of relatively small diameter for preventing entangling of the clothes content during reciprocation of the tub, or rather during washing 0 oration.

In the remaining figures of the d r awin'gs, the washing machine structure and means for reciprocating the tub has not been changed, but merely the manner of battling the tub has been disclosed in various manners. For instance, in Figs. 3 and 4, the blades 40 do not merge with the side walls of the tub, but merely lie adjacent the bottom and merge with the stem 42.

In Figs. 5 and 6, the blades are exactly the same shape as those shown in Figs. 1 and 2 of the drawings, but the central stem has been removed and the drain opening has merely a threaded plug or valve 47 inserted therein. In this instance the draining of the tub is accomplished by removing the plug or valve 47.

In Figs. 7 and 8, the drain mechanism is pfovided in a conventional drain opening 48 and valve 49, said drain mechanism being disposed exteriorly of the tub and at such a point that the entire water content of the es 40 are rounded at their upper plug controlling member 44, and a I point about the drain plug or valve inwardly and gradually mer ed into r tub is adapted to be drained therefrom by merged at an intermediate point 50, as

shown in Fig. 8. In this instance, also, there is no centrally disposed, upwardly projecting bafile to prevent entangling of the clothes or to support a drain mechanism.

Having described in detail the washing machine, and particularly the bladed tub portion, it might be said that the reach members 19 are reciprocated in the manner described herein, the same being of well known construction and devised, in the first instance, by the present applicant.

Although the present tub is disclosed as being round, nevertheless itis obvious that a tub fashioned either substantially rectangular in shape or with plural side portions,

might similarly have disposed upon its bottom upwardly projecting blade members adapted to create a violent water action during reciprocation of the tub.

A removable cover is adapted to be placed upon the inwardly projecting ends 51 of the tub and it is apparent that the 'rim 16 may be removed and the tub portion manually removed by simple vertical lift. The side portions of the tub are flared slightly, as shown clearly at 52, and also the connection between the side portions and the bottom of the tub is an unobstructed curved portion 53. It is thought from the above that the operation of themachine will be clear, and that the reciprocation of the tub will also cause reciprocation of the blade portions to create a violent water action and therefore a quick cleansing of the clothes content. The clothes are adapted to move in the path of the water disturbed by the upwardly projecting blade portions, and by the reciprocation of the tub itself, such movement being aided to some extent by the curvature of the tub wall near the bottom thereof. Said curvature also aids in directing flow of waterto the drainage aperture in the bottom of the tub, so as to facilitate emptying of said tub.

What I claim is:

1; In a washin machine, a tub, a centrally located b e member of relatively small diameter extending upwardly from the bottom of the tub, and a plurahty of upstanding agitating blades extendin upwardly from the bottom of the tub an dlsposed radially with respect to said bafile member the outer extremities of the top ed es of sai blades being curved upwardly an inwardly and gradually merged into the contiguous portions of below the plane of the upper end of said bafile member.

2.In a washing machine, a tub, a centrall located befle member of relatively smal diameter'extending upwardly from the radially with respect to said baflle member,

bottom of the tub, and a plurality of up standing agitating blades extendm upwardfrom the bottom of the tub an disposed the inner extremities of the top edges of said blades being extended downwardly to the bot- ,tom of the tub at positions spaced radially from said batlle member, the outer extremities of the top edges of said blades being curved upwardly and inwardly and gradually merged into contlguous portions of the .sides of the tub at positions below the plane of the upper end of said bafile member.

3. In a washing machine, a tub having the lower portion of its side wall curvedinwardl and gradually merged into the bottom 0 the tub, a centrally located baflle member of relatively small diameter extending upwardly from the bottom of the tub, and a plurality of upstanding agitating blades also extending upwardly from the bottom of the. tub and disposed radially with respect to said bafile member, the outer extremities of the top edges of said blades being curved upwardly and inwardly and gradually merged into contiguous portions of the sides of the tub.
