UNITED STATES PATENT OFFICE.
JOSEPH HADFIELD, OF NEW YORK, AND FLORENCE MCOONNELL, OF l BROOKLYN, NEW YORK.
SOIL-PIPE VENTILATOR.
SPECIFICATION forming part of Letters Patent No. 385,262, dated June 26, 1888.
Application filed January 12, 1888.
To all whom, it may concern:
Be it known that we, JOSEPH HADFIELD and FLoRENcE McCoNNELL, both citizens of the United States, residing at New York, in the county and State of New York, and at Brooklyn, iu the county of Kings and State of New York, respectively, have invented new and useful Improvements in Soil-Pipe Ventilaters, of which the following is a specification.
Our invention relates to improvements in soil-pipe vcntiiators of that type in which fresh airis admitted to the soil-pipe at the level of the ground.
Ihe object of our improvement is to prevent the escape of the foul air or gas in the soil-pipe through the fresh-air inlet of the ventilator when the pan of a water closet is dumped or whenever a large quantity of Watersuddenly enters the soil-pipe.
To this end our invention consists in the combination, with a soil-pipe open at its top end, of a back air-pipe communicating with the latter at or near its upper extremity, a valvecasing containing an air-inlet and passages F and G, communicating, respectively, with the soil audback air pipes, and a valve controlling the fresh-air inlet, all of which is more fully pointed out in the following specication and claims and illustrated in the accompanying drawings, in whieh- Figure l is a sectional elevation illustrating the application of our improved soil-pi pe ventilator. Fig. 2 is a longitudinal section, on a larger scale than the preceding figure, of the ventilator detached. Fig. 3 is a similar section showing the valves in a different position.
Similar letters indicate corresponding parts.
In the drawings, referring at present to Fig. l, the letter A designates the soil-pipe, the vertical portion of which is led above the roof of thebuilding. Its horizontal portion is connected with the sewer, (not shown,) and is provided with thc usual trap, B. The various closets, C, basins, 85e., arranged on the several doors, are connected wit-h the soil-,pipe in the usual manner. y
D is a back air-pipe, which is connected by pipes d with the upper portions of the traps of the various closets or basins.
Serial No. 260,519. (No model.)
Its upper end is connected with the soil-pipe A at a point above the highest closet or basin. The valvecasing E is located above the soil-pipe, and is provided with a passage, F, which is placed in communication with the soil-pipe by the use of a pipe, f. A second passage, G, is placed in communication with the back air-pipe D, and said passage G is also in communication with the passage F.
The fresh-air inlet His placed in communication with the outer air by means of a pipe, h. As seen in Fig. 1, the fresh-air inlet His closed by a. valve, I, which opens inwardly and permits the fresh air to enter the casing E and pass through the passage F and pipe f into the soilpipe, as indicated by the arrow 1.
If the contents of a water-closet pan or one of the several iioors of the building is dumped into the soil-pipe, the mass falling through the vertical portion of the same drives the air or gas toward the sewer, and as the air or gas cannot readily make its escape to the sewer on account of the trap B, it enters the valve-casing through passage F, Fig. 2. The pressure of the air or gas on the valve I closes the same, and the escape ofthe air orgas is cutoff in this direction. The air or gas can, however, make its escape through the passage G, connected with the back air-pipe D, as indicated by arrow 2, Fig. 2, and consequently itis lied above the roof of the building.
To render the valve I very sensitive and reliable, it is suspended from a beam, t', having a pivot on a post, fi', and an attached weight, i2, which counterbalances, or :nearly so, the weight of the valve. The valve can, however,
.be balanced in any other suitable way.
To prevent any possibility of the foul air or gas entering the valvecasing through the back air-pipe, an outwardly-opening valve, .I -such as a flap-valve-can be placed in the branch G. The top of the casing may be closed by a glass cover, so that theaction of the valve I can be observed.- A deector, K, is provided to deflect the air entering the passage H toward the passage F.
It Will be noticed that by the arrangement of devices herein described the foul gases are position from the top of the casing, and that the diaphragm can be removed from time t0 time when it is desired to inspect the valve. In such cases,where the fresh-air pipe h, Fig. l, is led upward, we provide an opening, li',
Figs.. 2 and 3, in the lower part of the valvecasing, which is closed by a ball-valve, h2, so that if water accumulates in said casing from any cause it will open the valve and iiow out of said opening.
What we claim as new, and desire to secure by Letters Patent, is-
l. The combination,with a soil-pipe having its upper open end extended above the build ing, of a back air-pipe communicating with the soil-pipe above the highest closet or basin, and a Valve-casing having a valved air-inlet and provided with a passage, F, communicating with the soil-pipe, and a passage, G, communicating with the lower end of the back airpipe, substantially as described.
2. The combination,with a soil-pipe having its upper openend extended above the building, of a back air-pipe communicating with the soil-pipe above the highest closet or basin, and a valve-casing having a valved airinlet and provided with a passage, F, communicating with the soil-pipe, and a valved passage, G, communicating with the lower end of the back air-pipe, substantially as described.
3. The combination, with a soil-pipe and a back air-pipe, of avalveeasing having'an airinlet and passages F and G, communicating, respectively, with the soil-pipe and back airpipe, an inwardly-opening valve controlling the air-inlet, and an outwardly-opening valve in the passage that leads to the back air-pi pe, substantially as described.
4. The combination,with the soil-pipe A and back air-pipe D, ofthe casing E, having an airinlet, H, and provided withV passages F and G, communicating, respectively, with the soilpipe and back air-pipe, an inwardly-opening balanced valve, I, controlling the airin1et, and. an outwardly opening valve, J, in the passage u that leads to the back air-pipe, substantially as described.
5. The combination,with thesoil-pipe A and back air-pipe D, of the casing E,having an airinlet, H, and provided with passages F and G, communicating, respectively, with the soilpipe and back air-pipe, a valve, I, controlling the air-inlet, a deflector, K, located above said valve, andal valve, J, in the passage that leads to the back air-pipe,substantiall y as described.
In testimony whereof'we have hereunto set our hands and seals in the presence of two subscribing witnesses.
