Specification of Iletters Patent. Pateptdljec, 15, 1914;.

Application filed July 29, 1911., Serial No. 641,291.

The invention in its broadest scope aims as its primary object, to provide a washing machine, including a pair of levers, connected at their ends to the plunger rods, and crossing one another approximately at their. central portions and pivoted to. a single post. The levers have connections with the single crank shaft for oscillating the same, which in turn reciprocates the plunger rods including their plungers.

A feature of the invention is the provision of a novel form of plunger, which is approximately triangular in cross section and hollow, and provided with a flange, which renders the plungers approximately dished, so as to cup and pound the clothes.

scope of what is claimed.

The drawing discloses only one form of the present invention, but in practical fields this form may require certain alterations, to which the patentee is entitled, provided the alterations are comprehended in the The invention comprisesfurther features and combination of parts as hereinafter set forth, shown in the drawings and claimed.

In the drawings Figure 1 is a view in side elevation of a washing machine, embodying the features of the invention. Fig. 2 is a plan view. Fig. 3 is a sectional view on' line 33 of Fig. 2. Fig. 4 is a detail viewof one of the plungers. Fig; 5 is a sectional view through the plunger rod. Fig. 6 is a detail view of a modified form of the plunger,

Referring to the drawings 1 designates. the tub or receptacle, in which the clothes and the suds are placed. Hinged to the tub or receptacle. as at 2'is a lid 3, having a central post or standard-4. Rising vertically from the lid and adjacent the hinged portion of the lid are two standards 5. In

bearings of the standards .5 a crank shaft 6 having crank portions? isjournaled. A

brace8 connects the two standards 5. Journaled on one. end of the crank shaft is a hand wheel 9 including a handle 10, whereby .motion can be imparted to the crank shaft; -Oonnecting with the crank7 of-the shaft are links 11', which in turn are connected to' similar links '12 by the eyes 13, therebeing nuts threaded upon the links .12 on each side of eyes, for holding the links 11 and 12 in their relative position. The links 12 are pivotally connected to one end vofeach of the crossing levers 14, as at 15. At the point where the levers cross, they are pivoted upon separate pivots 16 on the post 4, as shown in Figs. 1 and 2. The post 4: forms a part, of the base'plate '17 which is bolted or otherwise secured at 18 to the lid 3.

Pivoted adjacent the free ends of the crossing levers as at 19 are plunger rods 20, which penetrate the lid 3 of the tub or receptable 1, as is shown in the sectional view.

The plunger rods 20 are'provided at their lower ends with plungers or pounders 21. These plungers or pounders are constructed of sheet metal, and are hollow as shown.

The bottoms 22 of the plungersor pounders are surrounded by flanges23, thus rendering the plungers cupped or dished, as shown, so that when the plungers are reciprocated the 1 clothes may be cupped'and pounded, and

when pounded, a vacuum is produced in the clothes. The plungers or pounders are con 'nected to the plunger rods, so asto have a dished or cupped portions of the plungers,

slight swivelled sway or motion, so that the I pounders or plungers will not strike the clothes at the same place.

wringer 24, is erected on thewashing ma-- chine, the purpose of which is apparent.

. In Fig. '6 .a different form of plunger or pounder 26 is shown,which may be substituted for those shown in Fig. 3.

Asthe crank shaft is rotated, the cross ing 'levers or walking beams are oscillated on their independent pivots, which in turn operate the plunger rods and their respective plungers. As the plungers are reciprocated vertically the suds or other cleaning Incidentally a substance are forced and drawn through the clothes,-which removes the dirt.

From the foregoing it will be evident that therehas been producedv a simple, novel and eflicient washing'fmachine, and one which hasnot only heen found to be practicable,

laloor. The invention having been set forth, What but one Which Will save a great deal of is claimed as new and useful is':

In a Washing machine, a tub, a lid, a post right angles to each other, apounder con- Witnesses nected to each end of piv0tally connected to the'levers and extending Y adapted to swing relative thereto with the post,

standards thereon.

and the parts mounted In testimony vvhereoif I ha ve signed my presence of name to this specification inthe two subscribing wltnesses.
