SEWER-TRAP.
SPECIFICATION' forming part of Letters Patent No. 303,430, dated August l2, 188
Application med Feb'uary 1, 1884. (No model.)
To a/ZZ whom Azt may concern,.-
Be it known that I, JOHN WV.' GRIFFIN, of the city of Buffalo, in the county of Erie and State of New York, have -invented a new and useful Improvement in Sewer-Traps, of which the following is a specification.
This invention relates to that class of sewertraps which are employed for connecting cellar-drains with a sewer, and which consists of a receiver provided in its bottom with a suitable dischargeopening having a raised mouth which is covered by an overhanging bell, whereby the trap is formed.
The object of my invention is to provide a simple and inexpensive attachment to this class of sewer-traps, whereby the discharge-opening is readily closed against a pressure of backwater in the sewer, and it consists of the improvements which will be hereinafter fully described, and pointed out in the claims.
In the accompanying drawings, Figure l is a sectional elevation of my improv'ed trap. Fig. 2 is a bottom plan view thereof.
Like letters of reference refer to like parts in both iigures.
A represents the receiver, which may be of rectangular or other suitable form, and which preferably tapers downwardly and connects with the mouth of the drain leading to the sewer. B represents the dischargeopening formed in the bottom of the receiver, and b the raised mouth thereof. C represents the bell or curved plate,which overhangs the elevated mouth of the dischargepipe and descends with its edge below said mouth a sufficient distance to retain the level above the edge of the bell at such a height that the gas or air cannot pass from the discharge-pipe into the receiver A. The bell C is secured to the under side of a strainer or perforated plate,y D, which forms a cover for the receivcr A. The cover D rests upon lugs or ears d, ca st on the inner side of the sidewalls of the receiver A.
F represents an annular ring or plate Suspended from the bottom of the receiver A, be-
low the discharge-opening B, by means of screw-bolts or hangers g. rIhe bolts g are inserted through holes formed in the bottom of the receiver, and their lower ends pass through holes formed in lugs f, which'extend laterally from the annular ring or plate F. The ring F is secured to the bolts g' by screw-nuts g.
H represents a spherical or ball valve, which is seated in a depression or valve-seat formed in the ring F, immediately below the dischargeopening B. The valve I-I is preferably made of rubber or other suitable light material, so as to be buoyant and of sufficient strength to resist the pressure of the back-water. In the event of any overflow or rush of back-water in the sewer the valve H is raised by the pressure of water and seats itself against the dis charge-opening B, and the flooding of water through the trap and into the cellar is thereby prevented.
The lower end of the discharge-opening B is preferably beveled or inclined, as shown at t', to form a close seat for the valve H.
I claim as my inventionl. The combination, with the receiver A, provided with the discharge-opening B, of a ball-valve, H, seated in an annular plate, F,
arranged below the discharge-opening B, substantially as set forth.
2. The combination, with the receiver A, provided with the discharge-opening B, having an elevated mouth, b, and bell C, of an annular ring or valve-seat, F, suspended from bottom of the receiver A by bolts g and screwnuts g', and a ball-valve, H, seated in the annular ring F below the discharge-opening B, substantially as and for the purpose set forth.
Vitness my hand this 26th day of January, 1884.
JOHN XV. GRIFFIN.
