WASHING-MACHINE.'

To all whom it may concern.:

Be it known that I, IVILLTAM lVIT'r, a citizen of the United States', residing at Ripon, in -the county of Fond du Lac and State of l/Visconsin, have invented certain new and useful Improvements in lashing- Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in'the art to which it appertains to make and use the, same.

This invention relates to improvements in washing machines.

The object of the invention is to provide a washing machine having a reciprocating.

pounder and means whereby the clothes to be Washed may beslowly brought beneath the pounder so that all parts of the clothes may be acted on and the .wash water thoroughly circulated therethrough.

\'Vith this and other objects in View, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be more fully described and particularly pointed out in the ap ended claims.

n the accompanying drawings Figure l is a vertical sectional View through a washlng machine constructed in accordance with the invention. Fig. 2 is a top plan view of the same. Fig. 3 is an enlarged vertical sectional view through the pounder.

In the embodiment of the invention I provide an outer tub l in which is revolubly mounted an inner smaller tub 2. The inner tub 2 is provided with a perforated wooden bottom 3 while the sides of the inner tub are preferably formed of galvanized metal.

On the bottom of the outertub 1 is arranged.

al centrally7 disposed bearing 4C which is adapted to be engaged by the bearing stud 5 on the lower side of inner tub whereby the latter is adapted to freely rotate in the outer tub and whereby said inner tub is held above the bottom of the outer tub to permitV the water in said outer tub to circulate through the perforated bottom of the inner tub.' Theouter tubis provided with a suitable cover 6 on which-is mounted the operating mechanism of the machine. Said mechanism` comprising a drive shaft 7 which is revolubly mounted in bearing brackets 8 on the cover 6 and has ixedly mounted on its inner end a short crank arm 9 with which is connected the lower end of a pitman rod 10 the upper end.of said pitman rod being Specification of Letters Patent. Patented Dec. 21, 1909. Application filed December 14, 19t-)8. Serial No. 467,406.

an outer frusto-conical outer section 15 and l an inner cylinder section 16. In the upper portion of the outer section 1 5 of the pounder is arranged'a ball valve 17 whereby a suction action is provided when the pounder is forced downwardly into engagement with the clothes which are placed for washing in thc inner tub 2. The suction action of the pounder serves to draw the waslrwater through the clothes thus thoroughly eliminating the dirt therefrom.

Secured in the center .of the inner tub is an upwardly projecting operating shaft 1S in the upper end of which is formed a locking notch 19 with ,which is adapted to be engaged the squared lower end of a short shaft 20 which is suitably mounted in the cover of the outer tub and has on its upper end a spur gear 21l whichy is operatively engaged by the spur pinion 22, also mounted in suitable bearings on the cover of the outer tub. The pinion 22 is connected to or forms a part of a beveled gear pinion 23 which is operatively engaged by the beveled gear pinion 24 on the drive shaft 7. By the ar rangementof the gears' hereinbeforede scribed the inner tub 2 will be slowly re volved .within the outer tub to bring the clothes in the inner tub under the pounder.

The operating gearing for the inner tub is preferably so arranged thatl the tub will be revolved once to every twenty-five revolutions of the drive shaft, or, in other words, the pounder will be reciprocated about twenty-five times while the tub is making one revolution..

Any suitable means may be applied to the drive shaft 7 to operate the same, said means being here shown in the form of a crank wheel whereby the parts are manually operated.

From the foregoing description, taken in connection with the accompanyingdrawings, the construction and operation of the invention will be readily understood with` out requiring a more extended explanation.

Various changes'in the form, proportion and the minor details of .construction may be resorted to without departing from the principle or sacricing any of the advantifgesofthis .invention 'as defined in the appended claim.4

Havingf thus described, and ascertained .i the nature `of my invention, what I claim as lnew and desire to secure by Letters-Patent,

A Washing machine of the class described,A

comprising an outer vessel, an inner vessel revolubly mounted therein, a vertical oper-l ating Vshaft connectedto the inner vessel, a cover' for the outer vessel, a stubshaft extending through the cover, a bearing plate on the cover','a gear at the outer end of said shaft, a horizontal drive shaft 'mounted upon the bearing platev above said gear, a gear connection between said gear. and the drive shaft, a; vertical plunger extending operating `through the'cover, a guide mounted upon the cover for-'the plunger, 'ap'ounder at the lower end on-the plunger, a crank connecf ltion between the plunger and drive. shaft' for reciprocating the pounder, and a Separable connection' between the stub shaft and. shaft, 'whereby the cover-'and the.

operating mechanism for ythe pounder and operating shaft vmay be removed .Wlthout removmgthe inner vessel.`

'In' .testimony lwhereof I have lhereunto set my hand'in-presence of. tWo subscribing--
