Letters Patent No. 84,005, dated November 10, 1868.

IMPRovnD risentire-MACHINE.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, Osuna SoHmrMnL, of Chemnitz, in the Kingdom of Saxony, have invented a new and useful Improvement in \VashinglVIachines 5 and I do hereby declare the following-to be a full, clear, and exact description thereof, which will enable thoseskilled in the'art to make and use the same, reference being had to the accompanying drawing, forming-part of this specification, in which drawing- Figure 1 represents a longitudinal vertical section of this invention.

Figure 2 is a transverse section thereof.

Similar' letters indicate corresponding parts.

This invention relates to an improvement in washing-machines, of that class in which two or morebeat ers are used, whichworh in segmental tub, and to which an oscillating motion is imparted in opposite directions, by levers, cranks, or other equivalent means.

My present improvements consist, first, in the arrangement of flexible aprons over the oscillating beaters, iii such a manner that the clothes to be washedare prevented from lodging ou the beaters; second, in a double crank, extending from the driving-shaft in opposite directions, and having its wrists work in sliding boxes, attached to the beaters, whereby the beaters are suitably oscillated. A

A represents a tub, made of wood or any other suit able material, with a segmental bottom, forming a por tion of a circle, described from the centre of the rock- Ashaft C, from which the beaters B are suspended.

Said rock-shaft has its bearings in two standards, D, which rise from the sides of the tub, and the ends of the tub form abutments, against which the clothes to be washed are pressed bythe action of the beaters.

The beaters are arranged side by side, and they receivean oscillating motion in opposite directions by the action of cranks, levers, or other' equivalent mechanism In the drawing I have shown two cranks, E, which extend from the driving-shaft F in opposite directions,

and the wrists of which work in wooden boxes, a, fitted v into slots in the arms of the beaters, and so arrangedv that they can easily slide up'and down in said slots, as the motion of the cranks may require. -I use, by preference, wooden boxes, as they do not require any oiling, which would interfere with the success of the washing-operation.

The shaft F is revolved by handA or any other power, and, as the beaters oscillate in the tub, the clothes to be Washed are repeatedly compressedbetween the ends of said beaters and the ends of the tub, the clothes being about equally dividedbetweenthe boxes or receptacles formed between said ends and the beaters.

These boxes are covered up by dash-boards b and i doors c, and through these doors the clothes to be washed kare introduced or removed.

,At the inner endsof said boxes, on either side of the shaft, Vare arranged two aprons, d, of leather or other ilexible material. These aprons Vhang down over the beaters, and if a piece of cloth lodges on one of the beaters, and said beater recedes,4 the apron prevents said piece from being carried back, and sweeps it off from the back of the beater, so that all the clothes contained in the tub will be exposed to the uniform action of the beaters.

The bottom of the tub A is provided with, a series of longitudinal grooves, @,and into these grooves are fitted the tongues f, which project from the lower convex surfaces ofthe beaters, so that the clothes are effectually prevented from catching under' said beaters.

The water is admitted to the tub through a pipe, g, from which extend two branch-pipes, h, Vacross said tub. These branch-pipes are perforated throughout their entire length with a number of holes, through which the water discharges. v

The operation is as follows:

The clothes to be washed are divided into'the two boxes at the ends ofthe tub A, a small quantity of soapsuds is added, the doors c are closed, and hot water is admitted through the pipes g Il.. The beaters are then set in motion, and by their action the clothes are repeatedly squeezed and turned, until the dirt is almost entirely removed therefrom. y

During this operation the heat of the water is confined in the ends of the tub by the doors c and aprons d.

The doors care then thrown open, one piece of cloth after the other is inspected, and, if required, soap is applied to such spots as do not appear clean, and then the beating-operationis repeated until all the dirt has been removed; or, instead of this soaping-pro cess, the clothes maybe subjected to thel action of steam.

For greater convenience in `removing the clothes from the tub, I propose to make additional doors in the sides thereof. A

n After the clothes have been taken from the tub, I rinse them iu a suitable apparatus, such as commonly used for washing wool.

I do not claim as my invention the reciprocating beaters, such' having been used heretofore; but having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is

v 1. The aprons d, in combinatioi'with the beatersB and tub A, substantially as and for the piu'pose described.

2. vThe double crank E and sliding boxes a, in combination with the suspended beaters'B, substantially as and for the purpose described.

This specification signed by me, this 21st day of August, 1868.
