W, L. BELT'. as and Water valve for Sewerage-Connections- No.'202,2 19. Patented April 9, I878.
Inmzzzor 661";- {QIALQ -47 w N.PETF.RS, PHOTO-LITHOGRAPHER, WQQHINGTDN. D chom it may concern: known that I, WILLIAM L. BELT, of
the c of Washington, District of Columbia, have ented certain new and useful Improv nts in Gas and Water Valves for Sewe e-Connections, of which the following is a s ification:
My vention is more particularly adapted pipes and sewer laterals and connections, prevent the back flow of water and escap f gas from the sewer, while it will perm he drainage or waste-water to dischar tself without undue obstruction.
provement consists, first, in a valve approximately in the middle portion rface, upon one side of the pivot of ca than the other portion, in combiith a shell having a portion of its valve at formed upon an inwardly-projecting ge, and the other portion upon its rim, ereinafter described; second, in combinin ith a diametrically-pivoted valve an g-case, and a peculiarly-formed delate and apron, to direct the water through the valve-opening to-one side i e valve, as will hereinafter more fully In accompanying drawings, Figure 1 is a per ctive view of a circular valve; Fig 2, a lon dinal vertical section of the same;
Fig. a perspective view of a rectangular casin nd valve; Fig. 4, a longitudinal vertical tion of the same, and Fig. 5 a plan view the valve detached.
ith suitable flange a upon 1ts mouth for a chment to its connections, and has form pon its opposite edge aflange, a extendi inward around one-half of the valveopen1 ,and having its inner face smoothly to form a seat for the upper half of the will hereinafter appear. alve B is hinged upon ears c formed upon' shell A, either by means of pins a or by ans of a single stem passing across the b of the valve approximately upon its (1 eter. The valve B is formed with -elliptical sides in order to fit the at, which is made at a slight angle to of the pipe, in which position the I'I'ED STATES PATENT OFFICE.
M L. BELT, OF WASHINGTON, DISTRICT OF COLUMBIA, ASSIGNOR OF ONE-HALF HIS RIGHT TO DANIEL SMITH, OF SAME PLACE.
IMPROVEMENT IN GAS AND WATER VALVES FOR SEWERAGE-CONNECTIONS.
cific ation forming part of Letters Patent No. 202,219, dated April 9, 1878 application filed March 4, 1878.
weight of the water tends to open the Valve in one direction or close it in the other.
That portion of the valves circumference above the pivot-line c is of less diameter than. the portion of the valve below the same, and
bears against the rim a of the shell A, and
thus completes the seal. The offsets b bin Fig. 5,, connecting the shorter and longer di-,
ameters, are rounded and form bosses, through which the pivotspass; The bosses fit snugly into similarly-formed recesses in the shell, and make, with them, water and air tight joints. The longer diameter of the valve, being at the bottom, may be made of sufficient weight to rest closely upon its seat, but not offer undue obstruction to the passage of water through it in the direction indicated by the arrow in Fig. 2.
When the valve is placed in ahorizontal position, a d eflector-plate, C, is placed at a slight angle with the axis of the pipe, and, extending across the upper half of the valve, serves to defiect any water passing through the pipe upon' one side only of the valve-that portion having the largest area and opening outward. A small quantity or slight pressure of water will thus operate the valve and prevent it from counterbalancing itself upon opposite sides of the pivot. The valve is also intercepted by the deflector-plate, and prevented from overturning upon its pivots. An apron, C, extends downward from the deflector-plate, and serves to better carry out its purposes. The deflector-plate and apron may be held in place by pins or set-screws, and is preferably made removable, so that the valve and its seat may be easily reached to remove obstructions, if necessary. Reducing pipes of well-known form may be connected to either or both ends of the. valve-shell, to connect the same with pipes having a discharge area equal to the capacity of the valve opening. This, how ever, is only necessary when the valve is used in a horizontal position.
' llhe rectangular valves and shells shown in Fig. 3 are constructed upon the same principle and operate in a similar manner to the diskvalve above described, but are better adapted for closing the mouths of sewers in streetconnections. In this form the flange a of the casin g rests upon the brick-work at a suitable distance below the grade of the street and corner-boxing usually employed. Ears a? are cast upon, and are depending from, the lower edge of the shell, between which the corresponding ears formed upon the valve are fitted. The valve B is formed of parallel sides, the portion 13 upon one side of the pivots being of greater diameter and area than the portion B upon the opposite side of the pivots. The upper edge of the lower portion fits against the lower edge of the shell opposite thereto, and the lower edge of the smaller portion of the valve rests upon a flange, 0., extending beneath the same. A deflector and apron similar to that shown in Figs. 1 and 2 is either cast upon the shell or removable therefrom, as in the cylindrical form. The pivot-pins, in the form first described, may be placed slightly above the diameter of the valve, in order that the preponderance of weight may be below and keep the valve against its seat, and thus prevent the escape of gas, and the pivots may be placed nearer the discharge end of the shell, in the rectangular form, for the same purpose; or the valves may be properly weighted to hold them against their seat.
The valves shell or casing may be made either wholly or partially of Babbitt metal, to prevent rust and form a closer joint to obviate leakage. They may be employed in various connections to prevent the flow of water in one direction through the valve-opening and intercept it in the opposite direction.
The portion of the valve having the largest area opens downward or toward the sewer and the pressure of the backwater, and is kept closed against any pressure that might operate upon the opposite portion of the valve having a smaller area.
I claim as my invention and desire to secure by Letters Patent- 1. A valve to prevent the flow of backwater, pivoted approximately in the middle, and having the portions upon opposite sides of its axis of unequal area, in combination with a trap case or shell, substantially as described.
2. A valve to prevent the flow of backwater, pivoted approximately in the middle, and having the portions upon opposite sides of its axis of unequal area, in combination with the shell having the corresponding parts of its valve-seat formed upon opposite surfaces, substantially as described.
3. The combination of a valve pivoted upon its opposite sides, the casing, and a deflectorplate so arranged as to direct the water against one side only of the axis of the valve, substantially as described.
