AUTOMATIC FLUSH-TANK.

PECIFIGATION formingpart of Letters Patent No. 543,776, dated July 30, 1895.

Application filed May 7, 1395. Serial No. 548,452- (No model.)

To all whom it may concern.-

Be it known that I, ARNOLD FREDRIOK MOLLRING, a citizen of the United States, residing at Nebraska City, in the county of Otoe and State of Nebraska, have invented certain new and useful Improvements in Automatic Flush-Tanks; and I do declare the following to be afull, 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, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in flush-tanks, and the special object of my invention is to produce a float-operated valve carried in a tank or cistern, the said valve regulating the flow of water from the tank into a sewer-pipe which is to be flushed as the float rises with the water in the cistern, the valve being located at the the adjustability of the device, so as to allow companying drawings, which, with the-letters agreater or less quantity of water to flow from the tank into the sewer-pipes to be cleaned out.

To these ends and to such others as the invention may pertain, the same consists further in the novel construction, combination, and adaptation of the parts, as will be hereinafter more fully described and then specifically defined in the appended claims.

I clearly illustrate my invention in the acon which the valve-operating levers are mounted.

E is a projecting portion of the said framework, and on its free end is secured the vertical rod G.

H is a lever pivoted at h to the main framework, and the forward end of said lever has an elongated slot through which the vertical rod G passes.

J is a float having a central tube K passing through the same, and k is a flanged end beneath the float .to the said tube, and upon which flange the lever H rests.

L is a collar having a thumb-screw for regulating the height to which the float is allowed to rise.

M is a lever having a weighted end m, and near the middle of the said lever is pivoted the rod'N, which carries at its lower end the valve 0.

0 is an arm acting as a fulcrum, to the upper end of which is pivoted the said lever M.

P is a lever pivoted near its longitudinal center to an upright portion of the framework by means of the pin p, the rear end of the said lever P being connected by means of the link Q to the lever M, the forward end on the lever P being pivoted to the upper end of the bar R, which carries a lug 'r'near its lower free end and on which lug the lever H is designed rest when the the valve 0 is locked shut, as 7 seen .in Fig. 2.

U is a lever pivoted on the pin h, and is designed to turn with the lever H, and U is a weighted upper end to the said lever. The lever T carries the lugs V and is pivoted to an extension of the framework at W, and X is a post carrying a lug X at its upper free end and against which the lever U abuts when opened.

The operation of the device is as follows: In Fig. 2 the valve is closed, and as the water raises the float the lever H rises with the float,

the lever U turns with the lever H until the said lever U strikes against the lug V, which releases the lug S and allows the lever P to drop, and through the latters connection with the lever M the valve is lowered or opened, allowing the water to escape through the sower-pipe. WVhen the water in the tank has lowered a sufficient distance, the float lowering with the water depresses the lever H, which in turn causes the forward end of the lever? to be depressed by means of the lever I-l bearing down on the lug r on the bar R, and the rear end of the lever I, carrying the lug S, to be raised in position to rest on the shoulder of the lever T as the latter is caused to turn forward when the lever U strikes against the lug V, thus securely locking the valve closed until the float is again raised by the rising of the water in the tank.

Having thus described my invention, what I claim to be new, and desire to secure by Letters Patent, is-- 1. In combination in a device for flushing sewer-pipes from a cistern, a sewer pipe having a Valve controlled aperture, a framework carried on said pipe, a vertical rod carried on a projecting portion of said framework, a float vertically adjustable on said rod, a lever II pivoted to the frame work, its free end carried by said float, a lever U pivoted so as to turn with the said lever H, and designed, to cause a valve in the sewer pipe to be opened, as the float rises, substantially as shown and described.

2. In combination, a sewer pipe located in connection with a cistern, an aperture therein a valve (J regulating the same, the lever II pivoted to aframework held to said pipe, the rod G vertically secured to said framework, a float J having a central tube K which rides on said rod, a flange 70 on the tube K on which flange the slotted end of the lever II is adapted to rest and to be raised and lowered by the float, and means for automatically opening and closing the said valve as the float is raised and lowered, substantially as shown and described.

3. In combination, the sewer pipe, a valve seated in an aperture therein, a framework D, lever H pivoted to a portion thereof, a vertical rod G float J tube K having a flanged lower end, the forward free end of the lever II slotted and resting on said flange, the lever U adapted to turn with the lever II, the lever M pivoted to a fulcrum a rod N connecting said lever M to the valve 0, the lever P pivoted to the framework and connected by link Q, to lever M, the anchor lever T carrying lugs V, a shoulder on said lever 'l, a lug on lever l, and the bar R pivoted to the free end of the lever P, and a lug r at the lower free end of bar It on which lever H is designed to rest, all combined to operate substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
