WASHING-MACHINE POUNDER.

Specification of Letters Patent.

Patented Apr. 29, 1919.

Application filed February 10, 1916. Serial No. 77,477.

To all "whom. it may concern Be it known that I, LOUIS E. Draw, a citizen of the United States, residing at the city of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Washing-Machine Pounders, of-which the following is a specification.

My present invention refers more particularly to pounders for washing machines, and while the same can be operated by hand, I usually use the same in connection with washing machines, using the same as a dasher. One fornr of washing machine in connection with which I may use my inven tion is shown in Patent No. 1,073,075.

The various features of this invention and their particular advantages will readily become apparent from the following specification and claim.

In the accompanying drawing forming part of this specification,

Figure 1, is a plan view of the dasher or agitator,

Fig. 2, is a section on line -at of F ig. 1,

Fig. 3, is a plan view of a fragmentary part of the dasher, and

Fi g. i is a plan view of a detached part of the dasher.

In the drawing 7 is the Working member or shaft to which is attached in any suitable manner, the vacuum dasher or agitator 8.

The shaft 7 carries at its lower extremity the vacuum dasher 8, which I will now describe. The dasher 8 is formed of a conical or funnel shaped hood 25. This hood is supported on and connected to a spider or tripod casting formed of three outwardly and downwardly extending arms or ribs 26, diverging from a common base plate 27 made integral therewith, and through which plate passes a central hole or orifice 28, around which, on the upper side of said base plate 27, I form or place a number of protuberances or projections 29 within which is formed the valve seat 30.

The arms 26 of the spider just described form a riblike construction within the hood 25 and at their extremities near the peripheral edge of the hood, they extend downward perpendicularly beyond the hood edge or bottom forming agitators 31, outside of the hood ribs or arms 26, within the hood. The hood 25 and arms 26 are held together at points 32 by riveting, or any other means.

The valve is formed of a sphere or marble 33 and rests on the valve seat 30 at the mouth of the orifice 28, surrounded by the protuberances 29 which guide the valve 33 and keep it in limitation.

At the top of the hood 25 on its inside, I place a conical flange 34, in which I place port holes 35, in the present instance I use two, but I may use any number; these port holes also pass through the hood 25.

The conical flange 3% is tapped out at the top and screw-threaded, so that the screwthreaded extremity of shaft 7 can be screwed into the said conical flange, the hood 25 being cut away at its top to admit the shaft 7 to reach the flange as shown. On the outside of the hood 25, at its top where the shaft 7 passes through it, I secure a lock nut 36 onto the shaft 7, preferably screwing it in position. This lock nut 36, it will be noted, has a flaring rim or flange 38, which makes said lock nut of practically the same contour as the conical flange 34, so that said lock nut with its flaring flange 38 and the flange 34 fit, respectively, on the outside and inside of the funnel shaped hood 25 at its apex, holding it between them and in place against displacement by rivet connection 37. Thus it will be seen that the conical flange and lock nut form a bearing for the shaft 7 and thus also support it and hold the dasher 8 firmly upon said shaft and also firmly connect the parts of the dasher, at the top, making a firm, simple and efficient connection and combination of parts.

A space or pocket 50 is formed between the conical flange 34: and the top of the plate 27.

It will be understood that while I show only three arms 26 and agitators 31, I may use as many as I find expedient and I may make them of any shape. The hood 25 may be of any shape or contour, but I prefer the form herein shown and described, and the valve construction may be altered to suit any operating mechanism other than herein refered to above.

When the pounder is turned to the right and left in the clothes, the ribs 26 and agitators 31 are brought in contact with the clothes and stir them thoroughly, and as the pounder is moved up and down, the downward motion forces the water, fumes and the like, to pass up through the orifices 28, the force lifting the valve 33 off of its seat 30, the matter then passing into the space 50 and out through the port holes 35,

and when the shaft 7 and dasher 8 are moving upward the valve 33 is pulled down on its seat 30 thus creating avacuum or suction in the dasher which sucks and pulls out the dirt and extraneous matter in the clothes, also lifting them; this upward and downward motion being repeated as the dasher is alternately revolved to the right and left lifts and turns and moves the clothes in a thorough manner, thus producing highly desirable results in the Washing of the clothes.

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

In a washing machine pounder, a body part forming a hood, a plate therein near the top of said hood and spaced therefrom, a valve seat in said plate, said valve seat surrounded by spaced protuberances, a number of port holes in said hood above said plate, a sphere for said valve seat capable of movingon and oil thereof, a number of diverging agitating ribs in the inner side of said hood, said ribs extending into the hood and vertically downward beyond the edge of the hood,uthe lower peripheral edge of the hood extendin laterally beyond the vertical ends of the ri s.

Witness my hand at Cincinnati, Ohio, February 8th 1916.
