1 Claim. 1
This invention relates to a silencer for drains, and more particularly to such a device adapted to obviate the noise customarily made in drain pipes when air is sucked thereinto, during the drainage of fluid therethrough.
A primary object of this invention is the provision of a valve means adapted to be associated with a drain pipe, whereby air may be admitted to a drain pipe at a point adjacent the trap therein, thus eliminating the possibility of the formation of a vacuum in the pipe such as to occasion the sucking in of air from the inlet to the drain pipe from a sink, or the like.
An additional object is the provision of such a device provided for a one-way check valve, which will operate only at such times as the pressure within the pipe is reduced to admit air thereto, and which will correspondingly preclude the emission of gases or the like from the drain through the valve.
Other objects will in part be obvious and in part pointed out hereinafter and shown in the accompanying drawing, wherein there is disclosed a preferred embodiment of this inventive concept.
In the drawing:
Figure l is a view of the valve of the instant invention as applied to a drain pipe.
Figure 2 is a sectional view, enlarged, taken through the center line of the valve mechanism.
Figure 3 is a sectional view taken substantially along the line 3-3 of Figure 2.
Figure 4 is an elevational view of a constructional detail, and v Figure 5 is a fragmentary view, in elevation, of a still further constructional detail.
Like reference numerals refer to like parts throughout the several views of the drawing.
Having reference now to the drawing, the silencer of the instant invention, generally indicated at H3, is applied to a drain pipe I I, having a threaded aperture !2 therein adapted to accommodate the threaded end [3 of a cylindrical section I 4 comprising a portion of the silencer. Portion I4 is provided with a flange adapted to seat against either an opposed flange l6 surrounding the aperture I2, or against the surface of the drain pipe H directly, as desired. As best shown in Figure l, the silencer I0 is preferably positioned on a horizontally extending portion ll of the pipe at a point adjacent the trap 18 thereof, and on the opposite side of the trap from the end of the pipe 19 which extends to the drain from the sink, or the like.
Referring back now to cylindrical sleeve-like portion or member M, the same is provided at an intermediate point with a plate 25 having a plurality of aperture 26 therefore adapted to preclude the passage of foreign matter into the drain pipe. At its upper extremity, sleeve [4 is provided with a valve seat member 21 comprising a frusto-conical portion 28 terminating at its lower extremity in a flange 29, the outer periphery of which is adapted to be seated on the upper surface of cylindrical member l4, and hav ing two spaced plates 30 and 3|, one adjacent its apex, and the other positioned at an intermediate point therein, each having a bore 32 and 33, respectively, therethrough within which is slidably positioned the stem 34 of a valve 35 adapted to engage with the valve seat 21. The upper end of valve stem 34 is provided with a plate 36 secured in position thereon, as by a cotter pin 31, between which and the upper face of flange 29 is positioned a compression spring 38.
A cylindrical wire screen member 40 is adapted to be positioned around spring 38 and the valve stem 34 and valve seat 21, its upper extremity 4| being in abutting relation with the top 42 of a cover member 43 cylindrical in shape and adapted to rest on the upper surface of flange 29 to completely surround the valve and valve assembly. Cover 43 is adapted to be provided with a plurality of rows of apertures 44 to permit the passage of air therethrough, each being provided with a depending flange or shield 45 to preclude the ingress of large particles of foreign matter into the device.
From the foregoing it will be seen that there is herein provided an improved drain silencer, provided with a one-way check valve, which, when the pressure within the pipe I l is reduced, will be pulled downwardly by the reduced pressure therein against the compression of spring 38 to permit the ingress of air to the pipe, thus reducing the vacuum therein, but which will, when the pressure in the pipe is sufliciently great to expel gas therefrom, be held in closed position by the spring 38.
From the foregoing it will also be seen that there is herein provided a device accomplishing all the objects of this invention and others, including many advantages of great practical utility and commercial importance.
As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense,
I claim:
In a silencer for drains, in combination, a sleeve adapted to be secured in an aperture in a drain pipe, an apertured, frusto-conical member forming a valve seat positioned in said sleeve, a valve engageable with said seat, a valve stem extending upwardly through the apertures in said member, spring means positioned exteriorly of said frusto-conioal member and engaging the upper extremity of said valve stem, the opposite end of 10 said spring means abutting said frusto-conical member, biasing said valve toward closed position and adapted to yield on a decrease of pressure in said drain pipe to permit the ingress of air thereto, a screen surrounding said valve and said frusto-conical member, an apertured cover member surrounding said screen, and a guard plate in said sleeve below said valve and valve seat.
