upon on forcing the handle downward it, will coact with the links gend z' in an ob vious manner to put the gasket Z7 under compression and so seal the joint between the boiler and cover. The bearing points for the ends z" for the link i are so arran ed as to be somewhat inward of the bearing points g2 of the link g so that they will auto-- matically retain that position until the free end of the lever h is moved outward aGain.

Secured upon the flat portion da of: the cover, as by screws k, is a substantial baseplate y'. This plate forms the base for an upright supporting structure constructed as follows: Z is an upright which stands in a vertical plane coincident with the lon itudinal axis of the boiler. It is forme by a strip of metal bent transversely at about its mid-.length so that the legor portion Z at one side of the bend when the upright is arranged inverted on the base- `late stands inclined and the portion Z2 at t e other side of the bend stands vertically, said portions having their ends Z3 bent off' to form feet and secured by screws m to the plate n is another upright formed of a strip of metal bent also at its mid-portion into substantially inverted V-shaped form, the same straddling and bearing down on the upright Z, its portions n being riveted to Vfthewall d of the cover and projecting therefrom at fn?. Two of the aforesaid clamping means are arranged on the boiler a so that the links i thereof are adapted `to be operatively engaged with the ends n2 the same as the linkse: of the other clampsare engaged with the lugs e. `Vihere the uprights Z and 'n intersect they are formed with a bearing 0 (Fig. 3).

A pounder or agitato-r is adapted to be reciprocated vertically, the same including a stem p arranged to slide in the bearing o and penetrating the cover and the plate j and a pounder proper p which is concavoconvex in form, simulating the shape of the pointed end portion of an g, and is secured vat its apex to the lower end of the stem p so that its open-side is downward. My object is to agitate the water as much as Vpossible, and to this end I provide a pounder proper Whose suction on the up stroke will lift the water to the maximum extent; I have found that. if the device is formed substantially as I have specified it will accomplish this object.

The vertical portion Z2 of the upright Z is formed with holes q and g,'one above the other. The hole g' forms a bearing for a short shaft 'r on the inner end of which is fixed a pinion s and on the other end a friction-wheel t. The other hole g has fixed therein a stud u on which is journaled a gear o in mesh with the pinion s. On the stem p `is adjustably secured a collar fw which is pivotally connected with an eccentric pivot .fr on the gear wheel by a pitman y. This means for reciprocating vertically the pounder or agitator may be driven by a motor a which may be removably mounted in rests a on the cover and the shaft of which carries a grooved friction wheel z2 which is below the wheel t and is held in frictional contact therewith by the weight of the motor.

The cover is equipped with substantial handles 2.

In order to allow the steam to escape from the housing formed by the boiler and cover when the latter is clamped down in sealing relation to the former at the time the apparatus is in use I provide in the cover vents 3 preferably having upstanding venttubes 4, and in order to keep the water from spilling out of these vents, as an incident of the agitating thereof caused by the pounder and the boiling process, I provide a U-shaped baie plate 5 which is arranged opposite and under each vent 3 and secured to the cover.

So far as I am aware it is new in washing machines to provide as a supporting structure for means for actuating the agitator inverted bifurcated uprights arranged in planes crossing each other and one bearing down on the other and means to connect the lower ends of said uprights to the housing of the machine. In the construction herein actually set forth one of the uprights is mounted on the cover and the otherY the one Vwhich straddles the first) is adapted to be directl connected at its said ends to the receptac e, the supporting structure being thus substantially braced by being anchored to the then-wei hted boiler itself. Moreover. at this time t e gasket plays a part both in forming a seal and as a yielding medium to assume the compressing force exerted by the receptacle and supporting structure. By forming the upright Z with a substantially `vertical portion Z2 it is well adapted for the mounting of the gearing, while its portion 7, serves as a brace for the portion Z2, the upright as a whole, when formed as described, being a simple, inexpensive and durable means in which to guide the agitator and mount the gearin Having thus uIly described my invention. what I claim as new and desire to secure by Letters Patent is 1. Aywashing machine including, in cornbination, with ahousing comprising a re ceptacle and a cover therefor, inverted bent uprights forming a supporting structure and arranged in planes crossing each other and one straddlinar and bearing down on the other, the latter upright being mounted on the cover, means to detachablv clamp the first-named upright to said receptacle, an agitator projecting into the housing, and means on said structure to actuate the agitator.-

2. A Washing machine including, in eomhination with a housing comprising a reeeptahle and a Cover therefon an upright upon the housing above the Cover and oonaieting of a Strip ot meta] bent transversely of its length and having the portions on opposite sides of its hond extending downwa rdly from the hond one substantially vertically and the other at an incline. means to Connect the lower ends of Said portions to the housing', agitating means extending through the cover and having a bearing in the upright at the bend therein, and means arranged on the vertical portion of the Strip for actuating the agitator.

3. A Washing machine including, in oombination With a housing comprising a receptacle and a cover therefor, inverted bent uprights forming a Supporting structure and arranged in planes crossing each other and one straddling and bearin down on the other.y the latter upright belng mounted on the cover and consisting of a metal Strip bent transversely of its length and havin;lr ihe portions on oppositie sides of its bend extending downwardly from the loend one, Substantially vertically and the other at an incline, means to detaehably clamp the firstnamed upright to the receptacle, agitating means extendinfgi` through the cover and having a hearing in said structure, and means arranged in the vertical portion of said strip for actuating the agitator,

In testimony whereof I ax my Si gnature.

WILLIAM WI RTZ.
