Specification of Letters Patent.
Patented une 3, 1913.
Application filed April 6, 1912. Serial No. 688,874.
To all whom it may concern:
Be it known that I, FRED BARKER, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Sewer-Valves, of which the following is a specification.
This invention relates to valved outlets for catch-basins and the like, and it consists in certain improvements having for their object to provide a simple, substantial and durable outlet structure which may be readily established in operating condition and in which provision is made whereby the contents of the catch-basin may readily flow to the sewer or the like into which the catchbasin discharges but the odors and gases from the sewer will be effectually sealed. off against escape to the catch-basin and hence against escape up through the same to the street or other place where the catch-basin is placed.
The improved structure is fully shown in the accompanying drawing, wherein,
Figure 1 is a front elevation, the frame and the gate or valve it carries being removed; Fig. 2 is a front elevation of the frame; Fig. 3 is a vertical sectional view of the frame and gate orvalve; Fig. 4 is a vertical sectional view looking toward the wall of' the structure which carries the valve or gate frame; Fig. 5 is a sectional view taken on a medial line of Fig. 4, with the gate or valve frame illustrated in elevation, the viewpoint being at right angles to that of Fig. 4t. Figs. 6 and 7 are fragmentary sectional views of details; and, Fig. 8 is a side elevation of the structure.
a is a vertical laterally elongated wall adapted to form one side of a catch-basin and having along the upper edge thereof a backwardly extending sill b, 0 being vertical ribs reinforcing the bill b. Integral with the wall a and projecting rearwardly and centrally therefrom is a box-like structure (5 forming a chamber 6 and having a rearwardly projecting mouth f which affords an outlet from the chamber 6, the said mouth having an exterior flange 9 to which a section of sewer pipe is secured. The top wallportion of said structure cl adjacent to the wall a is flat, as shown, and forms the middle part of said sill b, the extremities of which are flanges on wall a as seen in Figs. 4 and 8; the said sill is designed to support the curbing of a street pavement. The bottom surface it of the structure (Z and mouth f inclines toward the discharge end of the latter. all 64 has an opening i which is semicircular at its lower end and rectangular at its upper end, the cross-sectional shape of the interior of chamber 6 corresponding to the shape of said opening. In its front face the wall a is formed around the opening 2' with a rabbet j, 7: being lateral recesseswhich open into the rabbet. Lugs Z may be cast on the back face of the wall or opposite these recesses, reinforcing the wall a where it would otherwise be weakened on account of the recesses m are holes formed in the wall a at the recesses. In the opening 6 of wall a is fitted a frame a which carries the gate or valve, the same having the same shape as the opening i and being'formed with an exterior flange 0 which fits in the rabbet j, its front face then being flush with that of the wall a. Projecting laterally from the flange 0 are notched ears 2) which are received by the recesses 7c, the notches of these cars and the holes we receive bolts 9 for securing the frame in place. The rear face of the frame is inclined downwardly (Figs. 3, 5 and 6).
r designates the gate or valve. This has the same shape as the opening in the frame a, which opening has the same shape, approximately, as the frame itself. Above the opening, wall a has two lugs .9 cast thereon, while the gate has a single lug 8 cast thereon at the top, and through these lugs is passed a pin t on which the gate may swing. The gate is normally held by gravity in the closed position (Fig. 3), a being a weight attached to the lower part thereof to insure this condition. But it will yield to the pressure of the contents of the catchbasin, allowing the same to escape into chamber 6 and hence into the sewer. My purpose is that when the valve is not held open by the pressure of the sewage flowing through the opening in the frame a the gate should effectually seal the said opening against the escape of gases into the catchbasin. I therefore provide for hermetically sealing any space around the gate when closed, as follows: The frame n is formed with a rabbet '0 whose surface w is beveled and in both of whose surfaces are preferably formed a series of holes 00. The gate 1 has the beveled continuous seating surfaces y and 2 formed at the same angle as the surfaces of the rabbet. The gate being nearly closed, some soft metal, in a molten state, such as Babbitt metal, is poured into this space, and when it sets it forms a continuous soft seat 3 which conforms exactly to the seating surfaces 3 and z of the gate; further, this seat will then be locked in place by projections 2 thereof extending into the holes m. In this way I produce between the gate and the frame a perfectly tight joint which will prevent the escape of the gases, while the gate is perfectly free to swing outwardly in response to pressure within the catch-basin.
It will be noted that the wall a has appreciable lateral dimension relatively to the at tached hollow structure d, thus forming anchoring wings at each side of this structure. By virtue of such construction the wall a provides one side of the catch-basin, as previously indicated, and is firmly held in the earth without the use of masonry, or other anchoring means, the weight of the struc ture (Z sustaining the wall in its proper relation to the catch basin. Furthermore, the sill b affords a support for the curbing of the pavement of the street, so that the present invention provides a structural element for sewers which can be incorporated as a unit in the catclrbasins thereof, and when so used also effectually supports the curbing of the pavement. It will be noted further that the frame a is so fitted into the structure d that it may be readily applied to or removed from the catch-basin after the structure d is in place, and by reason of the flange 0 and the rabbet j, which provide self-alining means for the frame a, the frame may be pushed into a definite and squared position,
where it is rigidly secured flush with the con tiguous face of the wall a by the bolts 9.
The box-like character of the structure d forming as it does a housing for the valve, receives and protects the valve at one side of the wall a, While the flange 0 of the frame is at the opposite side of the wall, the frame and its valve being projected through the wall when being positioned in the wall.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is As an improved article of manufacture, an outlet structure for a catch basin, co1nprising an elongated wall having a contrally-disposed opening formed therein, a hollow outlet body surrounding said opening and projecting from one face of said wall, the upper portion of said outlet body adjoining the upper edge of the wall being flattened and lying flush with said upper edge, an outwardlyextending horizontal flange formed on the upper edge of the wall at each side of said outlet body, said flanges merging into the flush flattened upper portion of the outlet body and constituting therewith a horizontal sill which extends throughout the length of said wall, whereby to support the curbing of the pavement adjacent to the wall, and means associated with the opening of the wall for controlling communication therethrough.
In testimony whereof I aflix my signature in presence of two witnesses.
