NITED STATES PATENT OFFICEO CHARLES HALSTEAD, OF NEW YORK, N. Y.

SEWER AND STENCH TRAP.

SPECIFICATION forming part of Letters Patent No. 237,383, dated February 8, 1881. Application filed December 24, 1880. (ModeL) To all whom it may concern:

Be it known that I, CHARLES HALSTEAD, of New York, in the State of New York, have invented a new and Improved Sewer and Stench Trap, of which the following is a specification.

The accompanying drawing represents a section of my improved trap.

Ais a chamber provided with afunnel-shaped cover, B, discharging into the mouth of the pipe 0. In this chamber A a vessel, D, is placed, divided by a partition-plate, a, in two parts, an upper chamber, a, and a lower chamber, m, connected together through an opening, to, in the plate a. In the bottom of the lower chamber, m, a valve, M, opening into said chamber, is arranged. To the opening of this valve M the induction-pipe O is attached, provided with a valve, N, moving in the valve seat of the valve M.

In the drawing hinged valves are represented, but it will be readily understood that ball or lift valves may be arranged and employed. 7

From the upper chamber, a, of the vesselD a pipe or passage-way, x, is arranged, leading to the bottom through the lower chamber, in,

to the end of which the eduction-pipe E, passing through the bottom of the chamber Ainto the sewer, is attached.

The chamber A and funnel-shaped cover B may be dispensed with, and the u'pper end of the induction-pipe 0 connected directly to the bottom of the sink; but I prefer to arrange the several parts, as above described, in a chamber, A.

Water and other matter from the sink or other places, when discharged, passes into the induction-pipe 0, through the valves N and M, into the lower part, m, of the vessel D, then through the hole to into the upper part, a, of said vessel D, and through the pipe or passage w and eduction-pipe E into the sewer. When the flow of the water ceases the valves M and N will close by their own weight, assisted'by the weight of water remaining in creating a partial vacuum in this lower chant ber, at, will drain almost entirely the pipe 0 of its contents.

The induction-pipe O, with its valve N, as well as the funuelshaped cover B, may be dis pensed wit-h and the chamber A attached directly to the bottom of a wash-basin, said chamber A receiving the bottom drainage as well as the overflow from the wash-basin. In

this case a strainer must be placed near the lower part of the vessel D, extending between the same and the side of the chamber A.

What I claim as my invention, and desire a to secure by Letters Patent, is

1. A sewer-trap consisting of the vessel D divided in two parts and connected, through an opening, 20, with the pipe or passagemfrom the upper part, and valve M in the lower part or chamber, m, in combination with the eduction-pipeE, and the induction-pipe 0, provided with a valve, N, situated close to the valve M, substantially in the manner and for the purpose described.

2. A vessel, D, divided into two parts, connected through an opening, to, with a pipe or passage-way, 00, from the upper chamber, a, and a valve, M, in the lower chamber, m, in combination with a vessel, A, and eductionpipe E, arranged to operate substantially in the manner and for the purpose set forth.
