CHARLES H. SHEPHERD, OF NEW YORK, N. Y.
AUTOMATIC DISCHARGE-VALVE FOR SEWER-PIPES.
SPECIFICATION forming part of Letters Patent No. 429,156, dated June 3, 1890.
Application filed August 28, 1889. Serial No. 322,254. (No model.)
To aZZ whom it may concern.-
Be it known that I, CHARLES H. SHEPHERD, of New York city, in the county and Stat-e of New York, have invented a new and Improved Automatic Discharge-Valve for Sewer-Pipes, of which the following is a specification, reference being had to the annexed drawings, forming a part thereof, in which Figure 1 is a sectional plan view, the section being taken on line 00 00 in Fig. 2. Fig. 2 is a vertical transverse section taken on line y y in Fig. 1, and Fig. 3 is a horizontal section taken on line .2 z in Fig. 2.
Similar letters of reference indicate corresponding parts in all the views.
The object of my invention is to construct an automatic discharge-valve for sewer-pipes of dwelling-houses and other buildings which will open under a given pressure of water and which will close automatically as soon as the water is discharged.
My invention consists in the peculiar construction and arrangement of parts, as will be hereinafter fully described.
To the lower end of the sewer-pipe A are attached ears B, in which is journaled a rockshaft C, carrying an arm D, to which is secured a valve E, adapted to close the end of the pipe A. To the rock-shaft C is also attached a lever F, provided with a weight G, adapted to close the valve E. Upon the lever F, between the weight G and the shaft C, is placed a casing H, containing a movable ratchet-bar I, which is pressed outwardly by springs a, placed in the said casing.
To a frame J, secured to the ears B, is attached a casing 1), containing an inclined plane 0. In the said casing b is pivoted a catch-lever d, the longer arm of which e11- gages the yielding ratchet-bar I, while the shorter arm projects beyond the lower end of the inclined plane 0. A spiral spring 6, interposed between the catch-lever d and the top of the casing 1), tends to press the said catch-lever downward.
To an arm f of the frame J is pivoted a lever K, carrying at one side of its fulcrum an adjustable weight g and at the opposite side a catch 71-, which is adapted to engage the shorter arm of the catch-lever d, the said catch it being pressed into engagement with the catch-lever cl by a spiral spring a, interposed between the catch h and the wall of the casing. The catch 77. carries a roller j, which rolls upon the inclined plane '0. In a right-angled arm 70, projecting from the frame J, is inserted a limit-screw Z, which limits the upward motion of the shorter arm of the lever K.
The operation of my improved valve is as follows: Then water accumulates to the prescribed limit in the sewer-pipe A, it presses down the valve E, carrying up the lever F, thus tilting the catch-lever d and drawing down the catch h, when the roller j, by engagement with the inclined plane a, pushes back the catch 7i and disengages it from the catch-lever cl, allowing the longer arm of the said catch-lever to rise, and thereby release the lever F, when the valve E opens wide and allows the contents of the sewer-pipe to escape. As soon as the pipe is emptied the weight g returns the valve E to its seat. It also brings the ratchet-bar I again into engagement with the catch-lever d, and the spring 6 of the said catch-lever causes the said lever to re-engage with the catch h, when the parts are ready for another operation.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In an automatic discharge valve for sewer-pipes, the combination, with the valve E and valveclosing lever F, provided with the spring-pressed ratchet-bar I, of the springpressed catch-lever cl, the spring-pressed catch h, provided with the roller j, the weighted lever K, and the inclined plane 0, substantially as specified.
2. In an automatic discharge -valve for sewer-pipes, the combinatiomwith the sewerpipe A, of the valve E, the rock-shaft C, provided with the arm B, the valve-closing lever F, the spring-pressed ratchet-bar I, carried thereby, the casing 19, furnished with the inclined plane 0, the catch-lever d, the spring 6, the catch it, the roller j, the spring 2', the weighted lever K, and the limit-screw l, substantially as specified.
CHARLES H. SHEPHERD.
