Application filed February 28, 1905. Serial No. 247,7/ i' T 0 1f/ZZ w/tom/ it T11/(ty concern:

Be it known that we, PHILIP VooRHnEs and HENRY JOHN TRAH, citizens of the United States, and residents of Logansport, in the county of Cass and State of Indiana, have invented a new and Improved Controlling- Valve, of which the following is a full, clear, and exact description.

Our invention relates to valves for controlling the flow through various conduits, it being particularly applicable to the rain-water conductors of buildings. Its principal object is to provide means for directing to waste the first flow through the conductorv at the beginning of a rainfall, this being liable to be fouled by dirt accumulated upon the roof and in the glitters, and then automatically delivering a succeeding flow to the cistern or other container which is to receive it.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a broken side elevation of one embodiment of our invention. Fig. 2 is a horizontal section on the line 2 2 of Fig. 1. Fig. 3 is a central transverse section through the cut-off or valve proper. Fig. 4 is a longitudinal section therethrough on the line 4 4 of Fig. 3, and Fig. 5 is a horizontal section taken above the lip of the controlling-conduit and showing another form of our invention.

A main conductor or conduit 10 is shown as terminating in branch conduits 11 and 12, which are to receive the waste and clean water, respectively. Mounted at the juncture of the conduits is a cut-off or valve 13, which is preferably generally trough-shaped and is so situated that when in one extreme position (that shown in full lines in Fig. 1 of the drawings) it directs the flow from the main conduit into the waste-conduit, while when in its opposite position(as is shown in dotted lines) it directs the discharge to the cleanwater conduit. The valve may be laterally reinforced at its center by adjacent double folds 14 14, formed by bending the material from which the valve is constructed, this being preferably sheet metal, first inwardlynntil it meets at the center and then outwardly, the folds lying in contact with one another.

The valve may be supported at one side by aA stud 15, which projects through the wall of the intersection of the conduits into an opening 16 at one side of the valve, while from the opposite side an arm 17, conveniently formed of Wire, first extends through two openings 18 18, which serve to fix the arm in place, then outwardly at 19 through an opening in the conduit-wall, and finally downwardly at 20, substantially parallel to the waste-conduit, to furnish a lever-arm weighted at its lower end 21. Connected to the arm 17 is an arm 22, extending upon the opposite side of the fulcrum of the lever, first encircling the portion 20 of the first-named arm at 23, then extending along the arm and being again bent to surround the portion 19 at 24, and finally projecting upwardly, where it terminates in an eye 25, the function of which will be hereinafter stated. Extending into the interior of the main conduit from one side is a lip 26, having an inclined upper edge at 27, which is shown as covered by a screen 2S. From the lower portion of this lip through the conduit opens a controlling-conduit 29, which projects downwardly substantially parallel to the main conduit, it lying within a vessel or receiver 30, which is movably mounted upon guides 31, carried by the main conduit, the connection between the receiver and guides being by means of pairs of eyes 32, fixed at each side of the receiver. Through the bottom of the receiver is a contracted outflow-opening 33 of considerably less area than that of the controlling-conduit, this opening leading into a spout or pipe 34, having its extremity lying within an elongated recess 35, which extends longitudinally of the main conduit and opens into the intersection of the conduits above the valve. The recess may be protected at its opposite sides by flanges 36 36, which tend to prevent wind from blowing the flowing water out of the recess. Along the inner side of the receiver, extending from top to bottom, is a passage 37, into which an overflow-opening 38 leads from a point near the top of the receiver. This overflow-opening, in connection with the opening 33,is sufficient to conduct the entire discharge through the controlling-pipe from the receiver into the recess 35, which leads it into the conduits. The receiver is supported by a link 39, connecting an eye 40, fixed to its lower extremity, with the eye 25 upon the lever-arm 22.

At times when there is no rainfall, and therefore no flow through the main conduit, the weight 21 is sufficient to hold the receiver in its extreme upward position and the valve tilted to deliver to the waste-conduit. Then at the beginning of a rain the first flow car- IIO rying the dirt from the roof will pass to the waste. A portion of it will be caught by the lip and directed into the receiver, the screen arresting any large particles of dirt and its inclined position serving to keep its meshes freed by the wash. This diverted portion of the flow enters the receiver and passes through the opening 33 into the spout and along the recess to the interior of the conduit, where it is directed by the valve with the main portion of the water into the waste. As the opening 33 is too small to permit the discharge of the controlling portion of the water as rapidly as it is introduced, it accumulates until it overbalances the weight and causes the receiver to descend, the spout traveling along the conduit-recess and the controlling-conduit being of such length that its discharge-opening remains within the receiver in all positions thereof. This movement of the receiver through the lever swings the valve upon its pivots until it assumes the position indicated by dotted lines in Fig. 1, when the entire quantity of water entering the main conduit passes into the branch conduit 12, the time of operation of the receiver being adjusted for any particular installation to eilect this movement of the valve after the water has become practically clean.

In the form of our invention illustrated in Fig. 5 the general operation is the same; but in this case instead of returning the controlling flow from the receiver to the conduits it is allowed to run to waste through the controlling-opening 41 in the bottom of the receiver and by overiiow at the top. Another arrangement of support of the receiver upon the lever is also shown, the upper arm having alined eyes 42 42, connected by an integral bail 43 and receiving oppositely-projecting trunnions 44.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 1. The combination with a main conduit having an elongated recess and a plurality of branch conduits, said recess opening into one of the conduits, of a valve associated with the juncture of the conduits, a movable receiver connected with the valve, and a pipe extending from the receiver into the recess.

2. The combination with a main conduit having an elongated recess and a plurality of branch conduits, said recess opening into one of the conduits, of iianges at opposite sides of the recess, a valve associated with the juncture of the conduits, a movable receiver connected with the valve, and a pipe extending Jfrom the receiver into the recess.

3. The combination with a main conduit having an elongated recess and a plurality of branch conduits, the said recess opening into one of the conduits, of a valve associated with the juncture of the conduits, a removable receiver connected with the valve, a pipe eX- tending from the receiver into the recess, a lip projecting forwardly from the wall of the main conduit, said main conduit having an opening in its wall within the lip, and a controlling-conduit leading from the opening to the receiver.

4. The combination with a main conduit and a plurality of branch conduits, of a valve associated with the juncture of the conduits, a movable receiver connected with the valve, a lip projecting inwardly from the wall of the main conduit and being provided with a downwardlyinclined edge, said main conduit having an opening in its wall within the lip, a screen supported upon the inclined edge of the lip, and a controlling-conduit leading from said opening to the receiver.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
