. v SEWER TRAP. No. 290.603. Patented Dec. 18, 1883.

UNITED STATES ATENT OFFICE.

LOUIS A. PELLIER, OF SAN JOSE, CALIFORNIA.

SEWER-TRAP.

SPECIFICATION forming part of Letters Patent No. 290,603, dated December 18, 1883.

Application filed June 30, 1883.

To all whom it may concern Be it known that I, LOUIS A. PELLIER, of San Jos, in the county of Santa Clara and State of California, have invented a new and useful Improvement in Sewer-Traps, which improvement is fully set forth in following specification.

This invention relates to ventilated sewertraps and it consists in an improved construction of trap, and also in the combination, with a trap, and especially a ventilated siphon-trap, of a stop-cock in the sole inlet-pipe of the trap, or, when there is more than one inlet-pipe, with each inlet-pipe, for completely isolating the trap and drain from the interior of the house.

The accompanying drawing represents an apparatus constructed in accordance with the invention.

The trap consists of a pipe, A, forming one leg of the siphon, a bend, B, provided with a screw, 0, in the bottom for cleaning purposes, and connecting the two legs of the siphon, and an upright, D, constituting the second siphonlcg. The part D consists of a T branch or branch having openings at each end, and an intermediate opening, the axis of which is at right angles to those of the end openings. The sole inlet-pipe A connects with the pipe A, and a stopcock, E, adapted to be turned by hand, is provided for hermetically closing the entrance to the trap, except when it is desired to have liquid pass. The ventilating-pipe F connects with the upper end of the branch D, and the outlet-pipe G with the middle opening of the branch. The branch D constitutes a gaschamber as well as a leg of the siphon. As

shown, it is of greater diameter than the inlet- (No model.)

pipe; but while this greater diameter may sometimes be of advantage in causing a larger body of liquid to collect in the trap, it is not essential, as it is obvious that it may be of the same size as the other parts of the trap, or even smaller, if it should be desired so to construct it.

The arrows indicate the direction of flow of the liquid passing through the trap, and also of the sewer-gas passing into the ventilatingpipe. This latter may be extended in any direction and to any desired height. The parts of the trap are shown connected byscrew-j oints 5 but other means of coupling could be used.

An S-trap is shown, but other forms could be made in the same manner. A Y- branch could be used in place of the T. 5 5

I clain1 1. The combination of the upright T branch, the outlet and ventilating pipes, the U-bend, and the upright pipe constituting the inlet leg of the siphon, substantially as described. 60

2. The combination, with the sewer-trap and the sole inletpipe thereof, of a stop-cock adapted to be turned by hand in the said sole inlet, so as to cut oft at will all connection with the trap, substantially as described.

3. The combination of the ventilating siphon-trap and the sole inlet thereof with a stop-cock adapted to be turned by hand in said sole inlet, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
