950,069. Patented Feb.22,1910.



Specification of Letters Patent.

Application filed April 9, 1909.

Patented Feb. 22, 1910.

Serial No. 488,989.

, T '0 all whom it may concern:

Be it known that I, HARRY E. FARRAR, a citizen of the United States, residing at Jackson, in the county of Jackson and State of Ohio, have invented a new and useful VVashing-Machine, of which the following is a specification.

This invention relates to washing machines and its object is to provide a simple device of this character which is durable in construction, can be readily operated and which will efiiciently clean the fabrics operated upon.

Another object is to provide a machine of this type designed to force water back and forth through the fabrics and thus quickly clean them without the necessity of rubbing them.

With these and other objects in View the invention consists of novel details of construction and combination of parts hereinafter more fully described and as pointed out in the claims.

In the accompanying drawings the preferred form of the invention has been shown.

Inthe drawings Figure 1 is a perspective view of a machine constructed in accordance with the present invention. Fig. 2 is an end elevation thereof, a portion of one of the cylinders being broken away.

Referring to the figures by characters of reference, 1 designates the base member of the supporting frame of the machine, said member being provided at each end with an upstanding arm 2, the two arms having alining inwardly directed extensions 3 at their upper ends to which are bolted or otherwise secured the downwardly extending terminal portions of parallel bars 4 which bars consti tute the top of the frame. Hoops or bands 5 are secured to the sides of the arms 2 adjacent the upper and lower ends thereof, these hoops or bands being disposed about the upper and lower portions of the cylinders 6. The cylinders are open at their lower ends and each of them has a piston 7 fitted air tight therein, each piston rod 8 being extended through an opening 9 formed within the movable cover 10 of the cylinder.

Extending through the middle portions of the bars 4 is a pivot bolt 11 on which is mounted an actuating lever 12, there being a handle 13 at the upper end of the lever while the lower end thereof is pivotally connected to parallel strips 14, the terminals of which are connected to the short downward extending arms 15 of opposed bell crank levers 16. These levers are pivotally mounted between the bars 4 on opposite sides of the lever 12 and the long arms 17 thereof extend beyond the downwardly projecting portions of the bars and are pivotally connected to the cross bars 18. These connecting bars have yoke like middle portions which engage the arms 17 and the terminals of the rods are pivotally attached to the piston rod 8 adjacent thereto.

The arm 19 is bolted or otherwise secured to one of the bars 4 and has a laterally extending handle 20 at its upper end. This arm and handle are fixed with relation to the bars 4 and constitute means whereby the mechanism described can be held stationary while the lever 12 is being actuated.

When it is desired to use the machine herein described it is placed within a tub of water or other receptacle containing soapy water and the fabric to be cleaned and is held steady by means of the handle 20.

The lever 12 is oscillated upon its pivot 11 and the strips 14 will cause the long arm 17 of the two bell crank levers to alternately elevate and depress the pistons, located at the two ends of the machine. During the up strokes of the pistons the water contained within the receptacle will be caused to flow through the fabrics and up into the cylinder 6 while during the reverse stroke of the pistons the water will be forced outwardly through the fabrics. It will thus be seen that a circulation of water will be established back and forth through the fabrics and said fabrics will be cleaned without the necessity of rubbing them.

It will of course be understood that various changes may be made in the construction and arrangement of parts without departing from the spirit or sacrificing any of the advantages of the invention.

What is claimed is 1. A washing machine comprising a frame, cylinders connected thereto and open at their lower ends, pistons mounted to reciprocate within the cylinders, opposed bell crank levers pivotally mounted upon the frame adjacent to the pistons, an actuating lever pivotally mounted upon the frame, and connections between said lever and the bell crank levers.

2. In a washing machine the combination with a frame, cylinders connected thereto and open at their lower ends, pistons mounted to engage Within the cylinders, a handle upon the frame and fixed With relation thereto, an actuating lever mounted upon the frame adjacent the handle and fimeans operated by said lever for reciprocating the pistons.

.upon the arms, cylinders engaged and retained by the bands, said cylinders being open at thebottoin pistons mounted to reeiprocate Within the cylinders, an actuating lever pivota'lly mounted between the bars,

means for transmitting motion therefrom to the piston, and a fixed handle extending from one of the bars.

In testimony that I claim the foregoing as my own, I have-hereto affixed my signature in the presence of tWo Witnesses.
