IMPROVBD WASHING-MACHINE. Y

To ALL WHOM IT MAY ooNoERN: A p

Beit known that I, JOHNVF. CHAMBERS, of Calistoga, county of Napa, State of California, have invented an Improved Washingfldachineyand I do hereby declare the following description and accompanying drawings are suiiicient to enable any person skilled in' the art or science to which it most nearly appertains to make and use my said invention or improvements without further invention or experiment. v i y The objectof my invention is to provide an improvedl washing-machine, so constructed that, by means of Awooden teeth, clothes, 8vo., may be rubbed upon a yielding corrugated metallic surface, in imitationof the rubbing upon a common wash-board by hand. l v

In order to accomplish this, I employ a square or oblong box, having a concave corrugated zinc bottom,

with a centre-piece of. Wood or other material, made smooth. The 'beating or rubbngapparatus*consists/of three or more boards, s'et edgewi'se in the box. The lower edges of the boardsV are slightly rounded, with a plane in the centre, and are pro'vided with teeth, which are made in opposite directions to the plane, similar to y sawltectln These beaters are suspended by an axle, which passesthrough upright standards, and has its bearlings ou the sides of the box, and are operated by ari-eccentric driving-shaft, having its bearings in standards.

To more fully explain my invention, reference is had to the accompanying drawings forming a part of thisv specification,- of which- Figure 1 is a side sectional elevation.

Figure 2 is a plan.

Similar letters of reference in each of the gures indicate like parts.

A representsA the box or tub of my machine, which may be constructed of wood or metal. If made of wood it should have a metal-lined b'ottom, B. The bottom, of the box is made concave bytwo pieces of corrugated metal or zinc, C C, similar to` the cerrugations of the common zinc washing-boards. These pieces are separated by a plane, D, which may be of wood, and attached to the bottom of the box. The pieces of zinc are unsupported' from behind, except as the' two ends are attached to the box, by which means elasticity or a yielding is had, which prevents the clothes from clogging. The beaters or rubbers E E E consist of boards 'set edgewise, with faces slightly rounded, and have teeth, F F F, cut'on them, similar to saw-teeth, but in opposite directions to their.` centres, which arel planes. These beaters are separated by standards, Gr G, to which I `they are attached. They are suspended by an axle, H, passing' through the standards, which has its bearings upon the sides of the box, so arranged that thebeatercan be easily removed 4from the bearing. Above, the axle is attached by a pin and arm,.ha.ving a band attached toit, which passes around an eccentric, I. A shaft, J, passes through this eccentric, having its bearings in standards attached to the sides of the box, with avdrivingwheel, K, at one end, and a crank or pulley, I1, at the other.

`The operation of my machine, so far as I have described it, is as follows,l to wit: Water, with soap or other compounds-employed in washing, is placed yin the box, and thefclothes introduced at4 either end, but should not be placed under the beaters, as these only are intended to serve to turn the fabrics over, and press orrub them against the corrugated are of the circle, having the same efect upon the pieces as if the hands were employed in washing with a common zinc-lined washboard.A The beaters are suspended in such a manner relative to the concavity that as the stroke is commenced from the plane or centre, the beatersarevery near the 'corrugations, and as they asce'nd'to the top, the space increases, the objectbeing to lessen the power necessary to operate the machine, as well as to carry the clothes up to the top of the water in the machine at each end of the stroke.

" Td draw the pieces back as each stroke is made, I employ curved wires, M M, with continuous ends attached,

whichare bent downward'so as to carry the clothes down with them, as the beaters move to and fro, as actu# ""`a`t`ed^by `eccentric in turning the driving-shaft. By this means the pieces are kept constantly turning, the beaters nbbilng them at thepward strokeat each end of the machine, and allowingthem to rise by disengage ment ea the centres of the corrugations.` 1 V `w `ger, N, vis attached to one end of the machinefor wringing the fabrics for drying, previous to which, Wever, thc beaters may be removed or elevated. I

Foif'hating `theneeessary water for boiling the clothes, I employ a furnace, O, which hasa heating-surface bou'tfth size of the bottom of the machine. This furnace has a irefbox, P, at vone end, and a iue, P',

leading from it. Adair-chamber, R, passes longitudinally throughthe furnace, and a removable cover, S, is placed at the rear end ofthe furnace.. i

The construction of the furnace may be varied to accommodate the size and shape of the machine, b ox, or tub. After the clothes have been suiciently washed they are passed through the wringer N, which is placed at one end of the machine, and the clothes hung out to dry, when the machine is removed from the furnace and the remaining fire or heat is used for heating the sad-irons, preparatory to ironing. A

By this means great economy is had in washing and ironing fabrics, and the heat and steam in dwellings be avoided, as the whole may be used out of doors.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is The combination of the toothed beaters or rubbers E E with the yielding corrugated metallic bottom C C,l constructed and operating substantially as described.

In witness whereof, I have hereunto set my hand and seal.
