Specification 01' Letters Patent.
Patented Feb. 22, 1916.
Application filed. March 27, 1914. Serial No. 827,649.
To all whom it may concern:
Be it known that I, JOHN P. DORAU, a citizen of the United States, residing at Jefferson, in the county of Jefferson and State of Wisconsin, have invented a new and useful Clothes-Founder; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to clothes pounders and the like. It is a device to facilitate the washing of clothes in the tub, being capable of performing the maximum amount of work with the minimum expenditure of energy. IVhile designed to give the greatest strength in the simplest mechanical struc' ture, it can be easily and cheaply made and will, therefore, more universally commend itself. The pattern herewith illustrated is thought to embody the'most eflicient design. Nevertheless, the inventor reserves the right to make any changes or alterations that are not foreign to his appended claim.
In the drawings :'Figure l is a planview of the improved clothes pounder. Fig. 2 is a section on the line 2-2 of Fig. 1. Fig. 3 is a sectional view on line 33 of Fig. 2. Fig. 4 is a sectional view on line 4- of Fig. 2.
The device consists essentially of the air' chamber '1 having the side walls 2 and the top plate 8. The cylindrical rib 4 runs around the entire lower edge of the walls 2 and besides giving added strength to the chamber 1 forms a rounded edge that will not tear or mar the clothes.
The air chamber is so shaped that it has its greatest width and therefore its greatest volume at points remote from the center and when it is remembered that the greater bulk of clothes is away from the center of the tub, the advantage of this increased volume is readily apparent. I
In Fig. 1 the relative proportions of the pounder and tub are shown, the tub being designated by the letter T.
A casting 5 serves as a support for the air chamber to which it is secured by the screws 6. This casting also carries the operating handle 7, the pin 8 serving to hold said handle in position. 1
A check valve is included in the design of the casting 5, the air inlet 9 leading to the ball valve 10 and the air outlet 11 into the air chamber 1.
The pounder is operated by imparting to it a reciprocating motion and at the same time an intermittent rotary motion and this may be done either by machinery or by hand.
If a machine is used, any conventional forms of combining a constant reciprocatlng motlon with an mtermittent rotary motion may be employed.
on valve 10 is released and equilibrium is restored by the inrush of air through the inlet 9. The repetition of these movements followed by the condensation and rarefaction of the air very quickly rids the clothes of all dirt without the harmful effects which I invariably follow scrubbing.
The invention having been set forth, what is claimed as new and useful is I A valve structure for a reciprocating casing, comprising a casting extending through the upper wall of the casing and depending below the wall, a duct formed in the-casting and passing from the upper surface thereof downward in the casting to a substantially elbow turn and provided with a valve seat adjacent to the'termination of the elbow turn, said duct then extending upwardly substantially parallel with its downwardly value seat being larger in diameter than the right-angled outlet opening, said upwardly extending portion immediately abovethe extending portion and terminating in "a valve seat and the first part of the. duct,
and a ball valve cooperatingwith the seat.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
