IMPROVEMENT IN SEWER AND STENCH TRAPS.

Speeilication forming part of Letters Patent No. 152,449, dated June 23, 1874; application filed i June 18, 1874.

To all ahom it may concern Be it known that I, HENRY H. YOUNG, of Newport, in the county of Newport and Sta-te ot' Rhode Island, have invented certain new and useful Improvements in Sewer or Stench Trap and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part ot' this specification.

My invention relates to an improved sewer-` p trap for use 1n houses, and is designed to prevent the stench from the sewer from coming back through the trap into the house. The invention consists in a trap that is closed by a door or fallin g valve that operates by gravity, and a separate and distinct sateguard is provided in a water-seal, all as hereinafter specified and claimed.

In the drawings, Figure 1 is a view in section of the improved trap, which may be located in the cellar-drain, or at any point where olia-l is led away to the sewer.

A is a basin, made water-tight, so as to hold the water in it at a level above the screen E. B is a box, provided with outlet b to the sewer. C is a door, hinged at the top to the inclined wall ofthe box B, and is held closed over the inlet port or valve by the action of gravity. D is the inclined cap, closing entirely around the front of the inlet port or valve, and provided at the bottom with a screen, E, or perforated surface.

The operation of the device is as follows: Oii'al thrown into the basin A will rise till it passes into the sewer-connections b, through the strainer E, the valve C, and the box B, and will continue to flow as lon as the height ot water in the basin A is 'greater than the. height of the bottom of the outlet-port b. It will then stop, and the door O will close by its own gravity, and prevent the return of stench; but the water in the basin A will still stand at a height above the screen E, and form a perfect water-seal, to prevent the return of' stench from the sewer in case the door should happen to be impeded; or, in case stench should escape into the inclined cap D while the water is passing through the door C, it is prevented from escaping by the water-seal in the basin A.

' It will be.- seen that the waste-has to pass through the screen O from below, and the waste does not, therefore, act, as ordinarily, to close the perforations by its own gravity, but drops from the screen.

It is designed with this trap and a streetsewer trap, for which I applied I'or Letters Patent June 9, 1874, which also prevents the escape of stench, to make a complete stenchtight system of sewerage.

That I claim isl. The stench trap composed of basin A, box B, gravity trap-door C, cap D, and screen E, the whole constructed and operating in the manner substantially as described.

2. The combination ot' cap D and screen E with the basin A, the whole adjustedto pass water through the screen from beneath, and to form a water-seal, substantially as and for the purposes setforth.

In testimony that I cla-im the foregoing I have hereunto set my hand this 17th day of June, 1874.

HENRY H. YOUNG.
