IMPROVEMENT m STENCH-TRAPS.
Specification forming part of Letters Patent No. 186,532, dated January 23, 1877; application filed December 18, 1876.
To all whom, it may concern:
Be it known that I, Dr. Tnnonon BOLDE- MANN, of the city of Washington, in the District of .Uolumbia, have invented certain new and useful Improvements in stench-Traps, of which the following is a specification:
My invention relates to that class of valves particularly adapted as back-pressure or flood valves, in which a free float is carried into its seat by the influx of the fluidinto the valvecasing, and is especially designed for use upon drain-pipes connecting dwellings with the sewers. t
In my application for Letters Patent filed October 3, 187 6, I have shown and described a valve of this character, adapted for use upon drain-pipes having no stench-trap between the house and the sewer-that is to say, upon drain-pipes composed of a series of straight sections-and in this case it became necessary to suspend the float-valve within its casing, to prevent the former from obstructing the outlet-orifice of the latter. But when the ordinary stench-traps are employed upon the line ofdrain-pipes, which isnow the case in almost all new buildings, instead of the usual surface cup-trap, I can obtain a sufiicient amount of liquid within the casing to float a free valve at all times, and prevent said valve from obstructing the outlet-orifice.
The stench -trap s usually employed have about six inches diameter; hence, I can ob tain, even by employing a casing having an inclined bottom, a sufflcicnt depth'of water to float the valve, which latter is of a diameter not exceeding eight or nine inches, and," being hollowand of light material, as described in the above-mentioned application, requires not more than threeor three and a half inches in depth of water to float the same.
In the accompanying drawings, Figure 1 is aavertical transverse section of a valve constructed according to my invention; and Figs. 2and 3 are similar views, showing a slight modification of the casing.
A is the casing, which, as described in the above-mentioned application, maybe of any convenient or preferred shapes-either cylindrical, square, hexagonal, octagonal, or semicylindrical-and is constructed substantially in the manner as described in said application and consists of body at, having an in clined bottom, 0), and forming a recess, M, below said bottom, for the purpose of setting the casing firmly in the ground or upon a suitable foundation. It further consists of the domeshaped head a provided with the inlet-nozzle a, said dome-shaped head being of curvilinear form, or bulging at the point ofjunction withmay be covered by some flexible material impervious to water, preferably with a rubber covering. s
It is evident that the waterlevel in the easing A must at all times be the same as that in the trap (J; hence, theinclination of the bottom of the casing must be regulated according to the arc of the circle described by the stenchtrap, which, in ordinary cases, is equal to the diameter of the pipe-that is to say, six inches; hence, a depth of water of six inches is obtained at the outlet-orifice, which depth gradually diminishes with-the inclination of the bottom of the casing A, which inclination I find to be sufficient when a depth of water of three inches is obtained at the highest point of the bottom; though, as above stated, this depth may be increased, if found necessary, by decreasing the angle of inclination of said bottom, or by increasing the curvature of the stench-trap.
In some localities, where the distance from the building to the sewer is very small, and therefore'would preclude the employment of a casing of considerable height, as is the case in many buildings in this and other cities, I employa perfectly spherical casigg, as shown by Figs. 2 and 3, in which E is the casing, made in two hemispherical parts, the lower part 0 having the outlet orifice or nozzle 6 and the upper part 9 havingv the, inlet-orifice 0 and not liable to become choked or impaired in its the seat for the float-valve arranged and constructedas already described. Each hemisphere is provided with a broad flange, F, by means of which the two parts e e are bolted or otherwise secured together, and made water-tight by interposing a suitable packer between the two flanges F F, which also serve as a seat or bearing, to set the casing in the ground or upon a suitable foundation. In this case the curvature of the interior surface answers to the inclined bottom of the cylindrical casing; and since an absolute waterlevel of six inches is obtained at the bottom of the casing, which is much more than is needed to float the valve, I prefer to give the outlet-nozzle e a slight inclination to reduce this level, and also to obtain a greater pressfire or fall, to more effectually carry off any solid substances that may enter into the casing. The upper hemisphere is also provided with a hand-hole, G, for the purpose of inspection or repair of seat and valve.
It is evident that with these constructions of casings, and their direct connection with the stench-trap, a valve is produced which is functions, like all the various valves heretofore employed, and found more or less impracticable, while at the same time said valve is automatic in its action, needing no attention before or after a storm, and embodying all the needed qualities for the purposes for-which it is especially designed.
Having now described my invention, what I claim, and desire to secure by Letters Patcut, is
1. Astenchtrap consisting, essentially, of
. the ordinary goose-neck trap and a valve-casing, the inlet-orifice of which forms the seat for a free spherical float-valve, substantially as described.
2. The combination, with a valve-casin g and a free spherical float-valve, having its seat in the inlet-orifice of said casing, of an ordinary goose-neck stench-trap, the two being connected together, so as to maintain a sufficient water-level within the casing to float the valve at all times, substantially as described, for the purpose specified.
3. The spherical casing consisting of two hemispheres having broad flanges, an inletnozzle forming the seat for a valve, and an outlet-nozzle and a band-hole, in combination with a float-valve, substantially as described,
for the purpose specified.
In witness that I claim the foregoing have hereunto set my hand this 18th day of Decem ber, 1876.
