. Be it known thetiI, CHARLES F. STAPLES, a citizen of the United Stetes. residing et .Detroit7 county of Wayne, State of Michian, have invented a. certain new and useful mprovement in Washing M22/shines, and declare the followin to be e full, clear, end fgthe seine, euch es wiil enable others skilled .in the nrt to` which it pertains to make and use the sinne, reference being hadto the yeccempenying drawings, which 'forme part of this specification;

- y invention relates to Washing machines.' The objectis to provide a. unitary washer and centrifugal dryer ofsimple, inexpensivev construction adapted for concurrent operethereof.

. partly in section of carried b tion lfrom the same source of power supply. A further object is to provide, in combinetion with a vacuum cup type of washing machine, a centrifugal drying basket adapted for rotation concurrently ofthe washer and driven by the same power. im ulses. v

further object is to mach-ine in which the -basket superimposes provide e washing centrifugal-drying the washing vat and 'is' driven by .the-mein drive shaft which extends through the vat and' from which shaft is likewise driven the Washing element ccnteined in the vat.

A further object is to provide a' washing machine having a centrifugal drying basket /superirnposing that portion of the vatin which the washing elements are disposed and adapted to 'discharge independently These and other objects, together with details'of construction will more fully appear from the following description, appended claims end the accompanying drawings, in which:

Potioned Keyed on the motor shaft e2 is e' driving gear-''. med by 'the niain drive shaft or .ep-indie g, which spindle extends upwmdly through thehottoin oi the vet.

Sleeved on thehousing h for rotation is e crosenrrn m held upwardly hy means of the tension sprin n, which spring is sup` portedby a shoul er ft2 formed on the heusing. This crees-arm carries at its extremi- A cam member o is secured to the drive shaft g to rotetetherevvith and is likewise secured to the bottom of the centrifugelbasket z forming e support therefor. The 'shape of this cam member is shown in Figs. l `sind 5. This cem engages the hub m2 of the cross-arm `m in such e manner that as the cani is rotated the cross-arn1 is depressed against the resistance of the spring n, producing a vertical reciprocation of. the crosserin concurrently with the rotation of the dryer.

To produce roteticin' of the crossnrin concurrently with its vertical reciprccation, the benrin face of the passage-Way through the hub 0% the cross-arm is provided with a zigzag groove g formed as shown in Fi 4 which is en elevation of the interior sur are of the hub rolled out Het. A pin p is secured to the houeing 7L upon which the hub is journaled and is adapted to travel in this zigzag groove g' as the crosearm. is .vertice-ily reciproceted. .The travel of this pin in the groove g during the reclprocation of the cross-umn produces rottion of the cross-v erm. It is apparent that the relative position of the Geer engegee geer g2 which is cerggrocve and pin might he reversed,-

.shaft for rotation therewith, a rotatable the pin being carried by the crosssarm and "the grooveformed in the shaft. The bevel of the zigzag groove is such at the apiece of the groove as to throw the pin off center as the cross-arm comes to the end of its stroke so that the crossarm will travel continuously forward in a given direction.

In the operation .of the machine, it will be seen that" the cross-arm carrying the vacuum cups will rotate and reciprocate concurrently with the rotation of the drying' basket.

What-I claim is:

1. In a washing machine, the combination of a vat, a driving shaft extending upwardly through the bottom of the vat a centrifugal drying basket positioned in the upper porn tion of the lvat and Amounted upon the drive reciprocating washing element mounted l.within said vat below said basket, spring means exerting. an upward yielding pressure onsaid washing element, Ia cam member carried by Said basket engaging said wash ing element and adapted to co-operate with the spring lmeans' to reciprocate the washing element as the basket is rotated, and means v eter enlarged beyond the; diameterof the lower portion and provided with an independent discharge outlet, a drive shaft ex tending through the bottom of said vat, and a drying basket mounted for rotation in the enlarged upper portion of the vat and perforated to drain in .such enlarged upper portion only.

3. In a washing machine, in, combination, a cylindrical vat having an upper portion of a diameter enlarged over the lower portion, a drive shaft extending upwardly through the bottom of the vat, a perforate drying basket positioned in the up er portion of.

the vat and mounted upon t e drive shaft for rotation therewith said drying basket be ing of a greater diameter than the diameter a'cylindrieal vat, a drive shaft extending through the bottom thereof, a centrifugal drying basket positioned in the upper portion of said vat and mounted upon Said drive shaft to rotate therewith, a housingsurrounding said drive shaft, va washingl element meunted upon said housing for rota- Tage said washing element vto rotate the same tion and reeiprocation, spring ,means adapti ed to normally support said washingielement in theuppermost position in said housing.`

and a'cam member rotatable with the drive shaft adapted to force the washing element downwardly against the resistance of said spring means once for each complete rotation of the shaft.

In testimony whereof, sign this speci# fication.
