THEODORE C. DOREDANT AND HENRY P. LPFEFFER, OF NEW ORLEANS, LOUISIANA.

FLUSH TANK.

Application filed October 5, 1823. Serial No. 866,762.

To all whom it may concern:

Be it known that we, THEODORE CHARLES DOREDANT and HENRY PHILIP PFEFFER, citizens of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Improvements in Flush Tanks, of which the following is a specification.

This invention relates to improvements in flush tanks, .the general object of the inven tion being to provide a siphon discharge for the tank with manually operated means for permitting the water level to rise to begin the siphon operation.

Another object of the invention is to so arrange the parts that the water level is normally held at a point just below the point where it will start the siphon action.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing our invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is a sectional view through a tank supplied with our invention and showing the parts in normal position.

Figure 2 is a similar View with the tank empty.

Figure 3 is a similar view with the parts in a position where the siphon action is just beginning.

Figure 4, is a detail view of the actuating means.

Figure 5 is a sectional view taken on line 5-5 of Figure 4.

In these views 1 indicates the tank and 2 the discharge pipe which is provided with a goose neck upper end for providing a siphon. The inlet pipe is shown at 4 and the flow of water from this inlet pipe is controlled by a valve 5. An arm 6 is connected with the stem of the valve and this arm is connected with one end of a channelshaped member 7. A block 8 is pivotally arranged in the other end of the channelshaped member and the rod 9 to which the float 10 is connected is attached to this block. A bar 11 is pivoted in the channelshaped member and this bar when in the member will engage the block and hold the same against tilting movement. A handle 12 is connected to a ring 13 in the bar by the links 14 so that when the handle is pushed down the bar will be lifted so as to free the block 8 and thus permit the float 10 to rise upon the pressure of the water in the tank, and the channel-shaped member 7 will drop under the action of gravity and the pressure of the water against the valve and this downward movement of the channel-shaped member will open the valve 5 so that more water will flow into the tank until the goose neck pipe 3 is covered and thus the siphon action will begin so that the water is discharged from the tank. As the water level descends the float 10 will drop and thus pull the block from under the bar and thus cause the bar to drop back into the channel-shaped member. When the siphon action ceases, due to the uncovering of the ends of the siphon pipe, the water will begin to rise in the tank until the parts are in the position shown in Figure 1 when the valve will close and no more water will enter until the handle is again operated.

The handle 12 is substantially lighter in weight than the bar 11 and its associated parts, and therefore when the parts are in the position as shown in Figure 2 of the drawings, the weight of the handle will in no way effect the movement of the bar 11, but will move under the influence of the weight of the parts as shown in Figures 2 and 3, while the normal position of the handle and parts are shown in Figure 1.

From the above it will be seen that we have produced a flush tank which requires no discharge valve for holding the water in the tank as the only valve used in the-device is the inlet valve.

It is thought fro-1n the foregoing tion that the advantages and novel features of our invention will be readily apparent.

We desire it to be understood that we may make changes in the construction and in the combinationand arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What we claim is A flush tank comprising a siphon discharge pipe, an inlet pipe, a valve thereon,

descripa channel-shaped member connected With the valve stem, a block pivotally arranged in the channelshaped member, a float having its rod connected with said block, a bar pivoted in the channel-shaped member and when therein preventing movement of the block a handle and means for connecting the same With the bar to raise the same out of the channel-shaped member to permit movement of the block by the float. 10

In testimony whereof We aflix our signatures.

THEODORE G. DOREDANT. HENRY P. PFEFFER.
