4 Specification of Letters Patent.

Application'filed September 2, 1909. Serial No. 515,843.

Patented Dec. 28, 1909.

To all whom it may concern.

Be it known that l, .-'-u.-'ous'ros W. SI-IANK, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in VVashing-B'Iachines, of which the following is a specification, reference being had therein to the accompanying drawings.

'12 on the'underside of the plate 9 just clear the bottom of the casing when the plate is This invention chines and more especially to certain features thereof insuring great efliciency, together with simplicity and durability of construction.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure l is a view in vertical section of a washing machine embodying features of the invention. Fig. 2 is a View in detail of a spider. Fig. 3 is a bottom plan view of a suction plate. Fig. 4 is a View of a modified form of driving means. -Fig.5 is a plan view in detail of the spider.

Referring to the drawings, an outer casing or vessel 1 preferably of the proportion of an ordinary washtub, has a IOl'l'lOVtlblC cover 2, detachablyfastened by suitable means, as hinge straps 3 engaging staples 4c. The casing is lined by a cage consisting of an upper ring 5, a lower ring 6, and rollers 7 journalod in spaced relation in suitable bearing apertures in the rings, three or more of the rolls being tastened'by screws 8 or the like to act as stay rods in holding the parts together and thus permitting the bodily removal of the cage which the rings and rollers form.

A suction plate 9 or circular apertured disk, has a central bearii'ig boss 10 adapted to he stepped on a stud l1 centrally secured on the casing bottom, of su'iiicicnt length to hold the plate at an interval above the bottom. Blades or radially disposed ribs in place. Pins 13 or like means for engaging clothes project. from the upper face of the plate.

A short. shait H with collar 1:) is rcmov-- ably journaled in a washer l6 and aperture in the cover 2 in alineinent with the stud 11.

relates to washing niaspider have Its upper end is squared, splincd or otherwise adapted for non-rotatably engaging a suitable crank 26. lts lower end is adapted to be inserted in the socket of the hub 17 of a spider and held there by a trmnsversc pin 18 or the like. Radial arms 19 on the stirrers 20 extending therefrom downwardly to engage clothes placed on i the plate. Preferably the stirrers are down bent Wire loops whose ends are clamped in grooves of the spider arms by a top plate 21 secured by screws 22 or the like.

In operation, clothes are placed on the suction plate and covered with water. The cover is then clampeddown with the stirrers extending into the bundle of clothes. By turning the crank around or swinging it back and forth, the clothes are likewise revolved and carry with them the plate. The paddles on the underside of this throw the water out and up between the rollerswhich keep the clothes away from the wall and give free passage to the water. This action draws or sucks the water above the plate down through the plate apertures and through the clothes. At the same time the clothes are given a twisting wringing motion as the handle is turned first one Way and then the other, the plate being momentarily retarded. In practice, it is found that the dirt from the clothes does not remain in suspension butts in great measure trapped by the plate and kept in the bottom of the machine below the clothes. The plate may be rigidly connected to the crank by a coupling shaft 23.as shown in Fig. 4. Likewise the rollers or cage may be replaced by vertical flutes or corrugations 24 in the tub sides indicated in said Fig. 4.

Obviously, changes in the details of construction may be made without departing from the spirit; of the invention, and I do notv care to limit myself to any particular form or arrangement of parts.

What .I claim as my invention is A. washing machine comprising an outer.

, upper ring, a lower ring and rollers in spaced relation journaled at each end in the rmgs, a prank shaft retatably securedo'n the cover i1 axial elinement Wlth the suction 'plate, a crank zietachably secured onthe upper end and stirring members on the lower end extendmg toward the plate, a spider with radial arms, detachably secured on the lower efed. of the shaft and wire 100p stlrrers secured on the splder arms. v 19 In testimony whereof I efiix my slgne'txire in presence of two witnesses.
