WASHING MACHINE.

Applieationled November 24, 1924. Serial' No. 751,768.

To all whom z't may concern.'

Be it known that We, CHARLES A. XAR- DELL, a citizen of the United States, residing in Utica, county of Oneida, and State of New York, and MORRIS F. JONES, a citizen of the United States, residing in the city of Utica, county of Oneida, and State of New York, have invented new and useful `Improvements in Washing Machines,y of which the' followingis av specification.

This invention relates to washing machines. In such machines the agitation of the clothes produces a repeated shock or blow upon the machine This is especially true in that type of washing machine in which the clothes-0r other material being washed is subjected to a tumbling action, being repeatedly lifted from the washing or cleanslng liquid and allowed to tumble or drop back into the same. As the wet clothes are of consider-able weight, the Shocky or blow is considerable. In prior machines, this shock or blow produces a continual vibration or .movement of the machine and a pounding action upon the floor upon which the machine is supported. A similar objection exists to a certain degree in most of the usual 4types of washing machines as a resultof the agitation of the material being washed.

This invention also relates to washing machines which are provided with centrifugal extractors or wringers. In that type of machine, avery violent vibration of the machine occurs when the extractor basket which supports the material being treated vis even slightly unbalanced, as by the uneven distribution of the loads'which are placed in the basket, the usual speed of rotation of the basket during the wrin ing or extracting operation being very hig for example 600 revolutions per minute or more. The vibration of the extractor basket is communicated to the body of the machine; and in priorl machines of this type the vibration tends to cause the machine to move violently around the floor.4 .Where the machines are designed for washing and' centrifugal wringing or drying, they have the objectionable pounding and vibratory action incidental to both of these operations.

This invention has for its princi al object to overcome the diliiculties or obJections referredto. Other objects, features and advantages will appear more fully in the following detailed specification and appended claims.

This application is a continuation in part of an application Ser. No. 675,909, filed N0- Vember 20, 1923. Y'

The accompanying drawings forming a part of this specification illustrate a machine containing one embodiment of my invcntion.

ln the drawings,

Fig. 1 is a vertical cross-sectional view of the machine showing the basket for supporting` the clothes or other material in position for the washing operation.

Fig. 2 is a like view showing the basket in posstion for the wringing operation.

Fig. 3 is a view taken on the line 3 3 of Fig. l.

Fig. 3n is a plan view of a portion of the driving mechanism. y

.Referring to the drawings, a tank or container 1 adapted to hold water or other cleansing liquid is provided with an upper washing and wringing chamber 2 in which the perforated basket 3 is supported. The tank 1 has a removable cover 1. The tank or container 1 thus acts as a casing for the basket 3. The chamber 2 has a liquid-tight bottom 4 beneath which is a chamber 5 containing the driving` mechanismfor the central operating shaft 6. The bottom 7 of the chamber 5 is secured to a suitable stabilizing support which will be described more fully hereinafter.

.standard or pedestal 9 in which the shaft 6 has a suitable bearing, said shaft being provided below the bottom 4 with a pulley 10 which may be -driven from any suitable drivingfmeans, 'such as electric motor 10', by the belt l1. This belt may be maintained at a suitable tension by the belt tightener 13 pivoted at '13 and held yieldingly in engagement with the belt 11 by spring 132. The motor shaft may be provided with a suitable clutch 102, such, for example, as shown in application for Letters Patent of the United States of Charles A. Xardell, Ser. No. 735,111, vfiled Aug. 30th, 1924, to cause the washing mechanism to be automatically clutched' to themotor shaft when the latter' `has attained a desired speed. The vertically arranged shaft of the driving motor (-10), extends upwardly through an op'ening (7') in the bottom wall (7) of the container (1). This opening is sufficiently large to permit tilting movement of the container (1) relative to the base or support in all directions, without interference from the shaft of the driving motor. A liquid-tight joint is formed between the bottom of the hollow standard or pedestal 9 and the bottom 4. To this end a gasket 12 of leather, rubber or other suitable material may be secured between the said standard and bottom.

To permit the shaft- 6 to be detachably connected with the basket 3, the said shaft is provided at its upper end with a socket 14 of irregular cross-section, for example, hexagonal, and the lower end 'ofthe shaft 15 secured to the bottom of the basketcoaxially therewith is of a corresponding irregular cross-section and adapted to lit into said socket. The shaft 15 is fitted to slide in a t-runnion sleeve 16 for al purpose which will be hereinafter described. f

The shaft 6 when connected with the shaft 15 through the socket 14 serves as a means for rotating the basket at a high speedy for the wringing operation.

To provide means for rotating the basket at a slower speed during the washing op? eration, the shaft 6 has secured thereto a worm 17 meshing with the worm wheel 18 on a horizontal shaft 19 journaled in the standard 9. The shaft 19 is provided with a' helical gear 23 meshinug with a similar helical gear 22on an inclined shaft- 24 supported by the standard 9. The inclined shaft 24 is provided with a socket 26 of the same cross-section as the shaft 15, so that the latter shaft may be operatively connected with said shaft 24. When it is desired to shift the basket from either of its operative positions- (that is, the positions for washing and wringing) to the other, the basket is lifted so as to disengage the shaft 15 from the socket 14 or 26 whereupon the basket and the shaft-15 secured thereto are tilted about the horizontal axis 16 of the trunnion 16 to a position withthe shaft 15 1n alignment with the desired socket after whichmthe basket is lowered ato cause the clutching of the shaft 15 with the socket. The' shaft 15 may thus be operatively connected either with the socket 26 to be driven about an axis at anl acute angle to the vertical at a relatively slow speed for washing or with the socket 14 to be driven about an upright axis at a relatively high i speed for drying. In the device shown the basketis rotated in a single direction during the washing operation, but by suitable mechanism (not shown) the basket may be oscillated or reciprocated about its axis during the washing operation.

When the basket is in the washing position it dips intp the washing or cleansing fluid as shown in Fig. 1, its axis of rotation being inclined or at an acute angle to the vertical.A The basket is provided with vanes or wings 3 which serve, upon the rotation of the basket during the washing operation, to repeatedly move the clothes through and lift the same out of the washing liquid and thereupon to permit them to fall or drop back into the washing liquid, the clothes being agitated by a tumbling action. During the drying operation the basket 3 as shown in Fig. 2 is arranged entirely above the water or other cleansing liquid in the tank 1, the moisture being extracted from the material in the basket by centrifugal action.

For eliminating the above mentioned objectionable effects of the shocks from the tumbling clothes and of the vibration resulting from unbalanced condition of the basket, I provide a shock eliminatingsupport upon which the tank or container is yieldably supported. This support, as shown,comprises a spider28, the arms of which are secured to'the bottom 7 of the tank or casing 1, as by brackets 29. The

.hub or central part of the spider has a universal or ball and socket connection 30 with a supporting base 31. The base may be formed with a number of legs arranged to rest on the floor. As shown the base has the same number of legs as the spider has arms.

The tank or container 1 is thus supported for universal movement at a single point 30 below the bottom thereof and in line with the axis of rotation o the shaft 6. To the brackets 29 are conne 'ted the upper ends of spiral tension springs 32, the lower ends of which are adjustably attached to the legs of the base by means of bolts 33 Vpassing through thea legs and having nuts on their lower ends bearing against the under side of the legs. The springs 32 serve to yieldingly hold the tank or container 1 and the parts connected thereto in proper relation to the base 31. By adjustment of the tension of the said springs by means of the bolts 33,

the resistance of the springs'32 to the'movement ofthe tank 1 with respectto the base may be varied to rovide for the varying loads in the machlne and also to equalize the tension of the springs.

While the shocks or blows resulting from the dropping of the clothes or other material durlng the washing operation are transmitted to the casing 1, the latter is -yieldable with respect to the base 3,1, and

`theshocks or blows are absorbed or eliminated so as notto cause an objectionablel pounding or movement of the machine on the floor. In the wringing operation the r rapidly rotating basket and the tank 1 are movable laterally about the jpint 30-and there is no objectionable vibration'of the base 31 due to unbalanced condition of the rotating basket, the tank or lcontainer being permitted to have a. balancing circulatory or gyratory movement very much like the movement of a spinning'top. During this movement of the v`tank relatively to the base, the belt tightener moves automatically to maintain an effective driving connection between the motor (which, as shown, is carried by the base 31) and the mechanism carried by the tank. y
