Description
PATENTED JUL 11 1871 W45 n0 vuw 6 V UNITED -STATEs SAMUEL LAWRENCE, OF NEW YORK, N. Y.
IMPROVEMENT IN STENCH-TRAPS.
Specication forming part of Letters Patent No. 116,967, dated July 11, 1871.
To all whom it mag/concern:
Be it known that I, SAMUEL LAWRENCE, ofthe city, county, and State of N ewYork, haveinvented a new and useful Improvement in Stench-Traps; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, in which the ligure is a side view of a stenchtrap to which my improvement has been attached, partly in section, to show the construction.
My invention has for its object to furnish an improved attachment for stench traps, which shall be so constructed as to prevent the trap om being drawn dry by the Siphon action of the discharge-pipe, and which will thus prevent any foul gas or odor from passing back from the discharge-pipe; and it consists in the combination of a valve attachment with the discharge-pipe leading from the stenclrtrap, as hereinafter more fully described.
A represents the pipe leadingl from a sink or water-closet. B is the stenclrtrap, and C is the discharge-pipe. lith the upper part of the dis charge-pipe C is connected a pipe, D, with which is connected a small valve-chamber, E, which I prefer to make square. In the bottom of the chamber E is formed a square or other shaped hole having an upwardly-projecting flange, e', all around it. F is the valve, which is made a little smaller than the chamber E and a little larger than the hole through the bottom of said chamber E. The valve F is hinged at one edge, and has a flange, j", formed all around its edge projecting downward into the channel or space between the ilange e and the sides of the chamber E, which space should be iilled with water, thus forming a water-joint which will effectually prevent any gas or offensive odor from passing up from the discharge-pipe C through the pipe D and escaping through the valve E F. To make the joint still more perfect a rubber plate, G, may be attached to the under side of the valve F to rest upon the upper edge of the lange e. The main passage d1 from the pipe D to the chamber E should lead into the upper part of said chamber E, but there should be another passage, d2, leading into said pipe I) from the lower part of said chamber E, so that, should the water set back from any stoppage of the pipe C or other cause and fill the chamber E, said -water will ilow off, upon the removal of said stoppage, through the passage d2. The passage d? should be above the lower edge ofthe ila-nge j" and below the upper edge of the flange c', so as not to draw olf the water that forms the water-joint.
By this construction, should the loW of water be suflicient to lill the discharge-pipe C and cause it to act as a siphon, the least tendency to a si- Y phon action will cause the pressure of air to raise the valve F `and enter the pipe D, ef'cctually preventing any siphon action upon the water in the trap B.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of a valve, E c F j", with the discha-rge-pipe of a stench-trap, substantially as herein shown and described, and for the purpose set forth.`
rIhe above specification of my invention signed by me this 27th day of May, 1871.
SAMUEL LAWRENCE. Vitnesses:
JAMEs T. GRAHAM, T. B. MosHER.
