Application filed July 7, 1914. Serial No. 849,516.

To all whom it may concern:

Be it known that 1, WILLIAM P. Arman SON, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Automatic Ejector-Valves for Sumps; and I do hereby declare the following to be a full, clear, and exact description of the vention, 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 the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in sump operated valves and particularly to an automatic ejector-valve apparatus actuated by a float, means being provided whereby a vent is normally established to the atmosphere and which is closed during a fluid pressure discharge.

My invention comprises various details of construction and combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawingsand then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which:

Figure 1 is 'a vertical central sectional view showing the application of my ejector valve apparatus to a receiver tank. 2 is an enlarged detail view in elevation and partly in section, and Fig. 3 is a view in elevation of the detail construction shown in Fig. 2 in a plane taken at right angles thereto.

Reference now being had to the details of the drawings by letter, A designates a sump or receiver tank through an aperture in the top of which a float rod B is adapted to have a longitudinal movement, and C designates a float within the reservoir in the tank and E, E designates swinging check valves of the usual type and regulat ing the openings E in the lower portion of the tank.

Mounted upon the sump cover is a stand ard F, the upper end of which is forked and supports two valve casings H and I, the former of which contains a ball valve L which controls a vent aperture N in a partition which divides said casing H into two compartments, said valve being normally held to its seat by gravity, and a pipe P leads from the tank into the upper compartment of the casing H, while a pipe P communicates between the lower chamher in the same casing and the atmosphere. The casing I is of similar construction to the casing H, being divided into two compartments, and O designates a fluid pressure pipe which leads to and communicates with the upper compartment of said casing I, and Q, designates a pipe leading from the. lower compartment of the casing and communicates with the tank.

Pivotally mounted upon the standard F is a lever T to the long arm of which the upper end of the float rod is pivoted at T and valve raising rods S and S are pivoted to said lever, one upon either side of the pivotal point F and each rod passes through a suitably packed gland and has its upper end concaved and upon which the valves are adapted to rest.

One end of the lever T is slotted as at T to receive the laterally projecting end T upon the arm T of the angle lever T which latter is pivotally mounted upon a pivotal pin T carried by the standard W fastened to the sump cover. The long arm of the angle lever T has a weighted end X forming a trip in order to give the valve a quick opening and which also assists in lifting the ball from its seat against pres sure of the same.

The operation of my invention will be readily understood and is as follows :The parts being in their normal positions, the valve L will be held from its seat, allowing the sump or tank to vent to the atmosphere through the pipe 1?, the valve-regulated opening N and pipe P leading from the valve casing. As the liquid rises in the tank and with'it raising the float and when the float rises a suflicient height to cause the lever T to tilt, closing the vent valve and opening the fluid pressure regulating valve, the lever T will tilt upon its pivot, thus assisting in raising the fluid pressure valve, which normally is held seated by the pressure of the float thereon. As the fluid pressure valve unseats, the fluid will pass through the pipe 0, the casing I and pipe Q into the sump or tank, thus causing the contents of the latter to discharge. The parts resume their normal position when the float and rod lower, a reverse tilting movement to the lever T causing the weighted angle lever to tilt back to its normal position, thus seating the fluid pressure valve and unseating the vent valve to the atmosphere.

WVhat I claimto be new is 1. A sump valve apparatus comprising,

in combination with a sump tank, a fluid pressure casing and a vent caslng, each d1- Videdby an apertured partition into two compartments, valves regulating the apertures in said casing, stems movable each throughan end of the casing and'adapted to alternately raise the valves from their seats, a lever pivotally mounted upon the forked bracket member fastened thereto,

valve casings mounted upon the arms of said-'member, each casing havlng an apertured partition dividing the easing into two compartments, pipes leading one from each compartment, a valve regulating each opening in said partitions, stems movable one through the end of each casing and adapted to alternately raise the valves from their seats, a lever pivotally mounted upon said bracket member and having pivotal connections with said stems, one upon either side of the member, one end of said lever being slotted, a float movable through the top of the tank and having pivotal connection with said lever, a post secured to the top of the tank, an angle lever pivotally mounted upon said post, a hook projecting from one arm of the lever and movable Within said slot, and a weighted member upon the other end of the angle lever.

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