WASHING MACHINE.

Application filed October 29, 1924. Serial No. 746,552.

- Machines, of which the following is a speci fication.

My invention relates to washing machines.

The invention has special reference to a washing machine wherein the container or tub is adapted to be moved through a continuous uninterrupted circular course.

The invention includes the mounting of a tub upon a support below the bottom thereof, and eccentrically with respert to the axial center of a driving means, wherein the tub body may be driven in a continuous circular course about the center of said drivin means and to means for controlling the tu from turning upon its own'axis.

The invention also includes the support of a tub at an angle inclined towards an axial line extension from the driving means wherein line extensions through the axis of said driving means will intersect a point located above the bottom of the tub.

The invention also includes a special character of tub support located beneath the tub, and the relationing of the same respectively to a driving member and to the tub, whereby the tub may be driven in an uninterrupted circular course about an axial line extension from the driving means, and to compensating means in association with the driving means and the tub, to control the turning of the tub upon the axis of its support.

The invention also 'includes'modification of the defined structure wherein the means, herein shown, for controlling the turning of the tub with reference to its supporting axis, may be modified in a manner to permit the tub to turn throughout a limited arc of its circumference during the period that the tub body is turned throughout the course of a complete circle. 7

The invention also includes. a special frame or basket support for the tub, to permit the latter to,be readily separated or removed from such basket support.

The invention includes details of construction and special combination of-parts and functioning utility of the same to produce certain operative results, hereinafter more particularly specified and pointed out in the claims.

In the drawings, Fig. 1, is a side elevation of the machine, the dotted lines therein indicating variation with respect to positioning of movable parts in the course of operation of the machine.

Fig. 2, is a vertical sectional detailed View of related parts functioning in the driving action of the machine, taken on the line 33 of Fig. 3, and

Fig. 3, is a cross sectional view on the line 2-2 of Fig. 2, the dotted line shown therein, indicating relative travel course location of associated parts.

The applicant has knowledge of known art relating to washing machines wherein a tub is supported upon a traveling inclined disc and held against rotation when its disc support is rotated, the same being illustrated in the patent to Greenberg, 1,330,801,

dated February 17, 1920.

Referring, now particularly, to the framing support shown'in the drawings; 10 and 11 are respectively upper and lower ring members attached to vertical framing members 12. 13 is designed to indicate a partial top closure member, designed, in practice, to be provided with a central opening above the top of a tub, designed to be'supported in the framing. 14, is a diagrammatic showing intended to represent a gear housing and gear content, the latter comprisingsuch gear members as mayserve-to drive shaft 15, connected therewith, in a constant direction. 16, refers generally to a crank arm member attached to shaft 15, and with its upper portion fashioned with a circular opening 17, disposed in an inclined relation with respect to the vertical axis of shaft 15. 18, is a tubular sleeve member turnably seated in opening 17 in'sa-id crank arm member 16.

which includes a central hub member and ill) radial arm members 21, terminating at their viding what might be termed, a basket housing or support for a tub member 25. To the hub portion 20, of tub support member 19, is fixed a stub shaft or post 26, positioned on ajline through the central axis of 1 terin the tub and depending downwardly from hub member of said tub'support andprojecting through andin turnablefit relation'with tubular member 18, supported in conjunction with crank. arm member 16,

whereby, through relative engage'ment'ot hub member 20 of the. tub support with crank arm member 16, the former is supported from the latter. In the relation. of

support-from shaft 15, asabove indicated.

it will appear that the axial center of support for the tub, is at an inclined angle toward a line extension from the vertical,- axis of shaft 15, and that'such axial exten- Jsion lines. will intersect at a point above the bottom of the tub support, and also it will appear that with the rotation of shaft 15, the axial supporting center for the tub will be swung about driving shaft-'15, and

similarly the tub will be caused to describe a similar circular. course whereby, it thetub is maintained in fixed position with respect to a turning upon itsaaxial. center, that a point preferably within the confines 'of'the tub coinciding with the intersecting axial line extensions of driving shaft-15, and censhaft 26, for the. .tub will be sub stantlally stationary, and constitutes the pre- ' venting the tub fromturning upon its own axis 27, is a stationary gear member fashioned' with a sleeve portion 28, and perforated flange portion 29, the latter adapted to .be fixedly seated in conjunction with gear. case member 14; and 30, is a sleeve member interposed between said gear and shaft the. latter being) 15. 31, is a gear member fixed to the lower end of tub centering shaft 26,- and; 32, is an idle gear, journaled in boxing member 33, supported in conjunction 'th screw mem er 34, having threaded supp rt in conjunction with the body of crank arm member 16, said idle gear being oooperativel related to gear members 27, and 31. The himctioning effect of the provision of such gearmembers is, that as shaft15 is turned to c'auseshaft extension member 26, from the tub support to be moved'about driving shaft'15, said shaft extension mem her, through its gear connection with fixed x gear member 27, and a proper relative relationing asto diameter and tooth members. serves to exactly compensate for the general turning movement of the tub from shaft 15, whereby said tub will be maintained in a stationary position with respect to a vertical plane through its axis, and also with.

respect to a point coincident withthe inter-- section of axial line extensions from the the driven shaft to driving and tub supporting means, whereby a constantly progressive tipping of the tub into constantly varying plane positions is efi'ected.

I desire to note here that 'it is within my conception. that compensating gear members 27, and 31, may be'varied with respect to diameter or tooth'member, or both, to the end of efi'ecting only partial compensation for the revolving action of. the tub about-J line extension through the axes of shaft 15,

in its e-fl'ect without such compensating meansto changethe position of the tub with res set to the axes of its support, whereby, 1m er such modification of gear relation over that shown in the action. of causing the tub to travel through the course of a complete 'circle, the travel of the tub with respect to its axis will be less or more than through a course comprehending a com- 8 plete circle about said tub;

We. name this modification as to relative motions about the driving center and axiallyof the tub, merely to'in'dicate means that might-be adopted to effect approximation of the result attained by the specific means herein shown, but with no suggestion as to equivalency of result attained.
