Application filed June 1, 1911.

Specification of Letters Patent.

Patented Feb. 27, 1912.

Serial No. 630,550.

To all whom it may concern:

Be it known that I, JOHN B. PRUDEN, a citizen of the United States, and a resident of Quanah, in the county of Hardeman and State of Texas, have invented certain new and useful Improvements in Gut-Otis, of which the following is a specification.

This invention is an improvement in cutofl's for water pipes, having for an object to provide a novel construction to control the supply of water discharged from a roof so that a given amount of the water may be conducted to a sewer or other oif-take until the roof has been washed, and the balance of the water be deflected into a cistern or other reservoir; and the invention consists in certain novel constructions and combinations of parts as will be hereinafter described and claimed.

In the drawing Figure 1 is a vertical longitudinal section and Fig. 2 is a front elevation, partly in section, of a cut-off embodying my invention. Fig. 3 is a side elevation of a portion of the apparatus. Fig. 4: is a cross section on about line 4:4 of Fig. 3.

In carrying out the invention, the water pipe A has a branch B and a valve C is pivoted at C and may be adjusted to the full line position shown in Fig. 1 to permit the water to pass down through the pipe A, or to the dotted line position indicated in Fig. 1, to deflect the water through the branch B. To this valve is fixed a depending lever G by which the valve may be operated and a weight C connected with the valve, operates to adjust the valve automatically to the dotted line position shown in Fig. 1, when the lever C? is released by the detent mechanism presently described. This detent mechanism includes a catch D pivoted at D and having an arm D with a seat D to engage the pin C at the end of the lever C and the lever D has a handle extension D beyond the seat D for convenience in manipulating the said lever. The catch D also has a bail-shaped portion D provided with an arm D engaging with the edge of a mutilated wheel E in a train of gears F driven by a water wheel G, whose blades G are operated upon by the water passing through the water pipe. The wheel E has a notch E into which the pin D on the arm D may pass to permit the catch D to drop and release the lever C when the said pin D registers with the notch E as the wheel E is revolved. The wheel E is connected by a ratchet H with its wheel I of the train F, so that in setting the valve the wheel can be readily turned back to the desired position for setting the wheel for a new operation.

If desired, the wheel Gr may be set a little farther back or to the left from the position shown in Fig. 1 to let the water hit the blades a little farther from the pivotal center G of the wheel.

In the operation'of the invention, when the parts are as shown in full lines in Fig. 1, in case of a shower, the water will pass from the roof down the pipe A and will act on the wheel G to revolve thesame and this through the train F will turn the mutilated wheel until the notch E comes into position to permit the passage of the pin D into the saidnotch when the .catch. will drop from the full line position shown in Fig.1, releasing the lever C from engagement with the seat D so the weight C can tilt the valve to the dotted line position shown in Fig. 1, when the balance of water will pass through the branch '13 into the cistern or other receiver.

In practice, it is preferred to inclose the train with the removable casing J, as shown in Figs. 2 and 3 of the drawing.

I claim:

The improvement herein described comprising a pipe having a branch, a valve pivoted at the juncture of the pipe and branch and adapted to shut off the branch or to be adjusted across the pipe to deflect water out through the branch, a weight for operating the valve in one direction, a lever projecting from the valve, a pivoted catch having an outwardly projecting arm provided with a seat for engagement with the valve lever to secure the valve in one position, said arm having a handle extension, and the catch having a bail-shaped portion, a Water Wheel the catch, all substantially as and for the operating in the Water pipe, a train operpurposes set forth. ated by said Water Wheel and a mutilated Wheel having a ratchet connection With the JOHN PRUDEN' train and provided with a notch, the bail- Witnesses: shaped portion being provided With an arm W. B. HAMPTON,

' Which may project into said notch to release W. HOETZEL.
