C. E. M COY WASHING MACHINE Original Filed Dec. :5, 1920 Patented Nov. 6, i923 air stars than @FFHQE WASHING TEACHINE.

Original application filed December 3, 1920, Serial No. 428,020. Divided and this application filed December 17, 1921.

To all whom it may concern Be it known that I, CHARLES E. MCCOY, citizen of the United States, residing at Logansport, in the county of Cass and State of Indiana, have invented certain newand useful Improvements in Washing Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to improvements in washing machines and this application is a division of my application No. 428,020 filed Dec. 3, 1920.

The primary object of the present invention is to furnish a light, strong, inexpensive pounder for use in pounder type washing machines.

Another Object of the present invention is to furnish an improved pounder formed generally of sheet metal and constructed to prevent tearing of the articles being washed.

Another object of the invention is to provide an improved pounder which may be readily cut from sheet metal and inexpensively assembled, so that the pounders may be manufactured in a factory where sheet metal articles are made.

With the foregoing objects outlined, and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawings and more particularly set forth in the appended claims.

Referring to the drawing:

Figure 1 is a perspective view of my improved pounder.

Fig. 2 is a side view of the same.

Fig. 3 is an end view.

In the drawing, 1 designates a plurality of sheet metal angle irons arranged in parallel relation but with their horizontal portions 2 directed in opposite directions. Connected to these angle irons are a plurality of channel shaped sheet metal crossbars 3, the longitudinal edges 4 of which are curled or bent backwardly on themselves to provide curved surfaces at the edges of the channel shaped members. Arranged in each of the channel shaped members is a lining bar 5 preferably of wood, and the lining bars and channel shaped members are Serial No. 523,008.

connected to the angle irons 1 preferably by means of bolts 6. Three channel shaped members are shown in the drawing but it is obvious that a greater or less number may be employed for different sized. machines.

In operation the pounder is reciprocated by means of a bar 7 and it functions to force the article being washed downwardly in the washing machine tank. During this operation, the water in the tank flows upwardly into the spaces 7 provided between the sides of the channel bars and the sides of the liner bars 5 and this water works longitudinally of the channel bars and finally is ejected at the ends of the channel bars. When the plunger is raised above the water surface in the tank, air is trapped in these spaces 7 and some of this air is carried beneath the water when the plunger descends, so that the present plunger functions similarly to the so-called vacuum plunger-s.

From the foregoing, I believe that those skilled in the art will readily understand the invention, and it is obvious that changes may be made in the details illustrated without departing from the spirit of the invention as expressed in the following claims.

What I claim and desire to secure by Letters Patent is:

1. A washing machine pounder comprising a series of parallel arranged open-endzed inverted channel-shaped bar s, liner bars substantially filling the channels of the channel-shaped bars and having their side walls spaced from the inner surfaces of the side walls of the channel-shaped bars, and means for securing said channelshaped bars together and said liner bars to the channel-shaped bars, the lower edges of the side walls of said bars having rounded surfaces to prevent tearing of materials being washed.

2. A washing machine pounder comprising a series of parallel arranged sheet metal inverted channel-shaped bars having diverging side walls, liner bars arranged, in the channels of the channel-shaped bars and having parallel side surfaces spaced from the inner surfaces of the side walls of the channel-shaped bars .to provide recesses, longitudinal bars arranged. at right angles to V 5 2 in which the edges of said side Walls of the channel-shaped bars and means connect ing said longitudinal bars, channel-shaped bars and liner bars together.

3. A'pounder ofthe kind defined by claim In testimony whereof I hereunto affix my signature in the presence of tWo Witnesses.
