MILTON CHRISTOPHER HENLEY, OF NElV YORK, N. Y.
cAs-vENTiLAToR FOR MAlNS.
SPECIFICATION forming part of Letters Patent No. 679,619, dated July 30, 1901.
Application filed March 16, 1901. Serial No. 51,488. (No model.)
To aZZ whom, it may concern:
Be it known that I, MILTON CHRISTOPHER HENLEY, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Gas-Ventilator, of which the following is a full, clear, and exact description.
This invention relates to devices for preventing the entrance to cellars and basements of dwellings or the like of gas escaping into the ground from defective gas-m ains or otherwise; and the object is to provide a device of this character especially applicable to the condition of streets that are paved with concrete, asphalt, or like material or ground which is frozen, thus preventing the upward escape of gas from the subsoil.
I will describe a gas-ventilator embodying my invention and then point out the novel features in the appended claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a side view, partly in section, of aventilator embodying my invention. Fig. 2 is a plan view. Fig. 3 is a sectional elevation of the same.
With the stated object in view the ventilator comprises a casing 1, designed to be seated in the loose ground or subsoil at any suitable place. As here shown, it is placed underneath the sidewalk 2 at the inner side of the curbing. The upper end of the casing extends through the sidewalk and is provided with a perforated top 3. Extending in opposite directions from the portion of the casing placed in the loose dirt or subsoil are pipes 4, which are open at the ends and of course open into the casing. These pipes will preforably be inclined downward, as shown in the drawings, and extended laterally from each pipe 4 are a number of branch pipes 5, which are also open at the ends. Short pipes 6 are extended at a downward incline from the 0pposite sides of the casing 1 and near its top, and short pipes 7 are extended at a downward incline from the front and rear of the casing near its lower end. These short pipes of course are open at the ends.
The ventilating-casing 1 in practice will be placed at the center of the front line of the house, and the pipes A will extend along the Whole front of the house or buildinglot. While I have shown but one ventilating device, it is obvious that two or more may be employed-that is, one as shown in the drawings and another one arranged near or within the areaway of the building, in which case they are to be connected by a pipe 8, so that the gas from the device in the areaway or near the same will pass through said pipe 8 and out through the grating or perforated top 3 of the casing 1.
In operation should a leak occur in the gasmain a; or from any other gas-carrying device the gas will pass through the subsoil underneath the pavement of the street and find its way into the open ends of the several pipes and then pass through these pipes into the casing 1 and out through the perforated top. Thus the device acts as a barrier to prevent the discharge of gas into a house or cellar. By providing a great number of pipes and branches and inclining the same, as shown, a large area of ground is covered, or, in other words, the escape devices for gas are arranged at varying depths in the ground.
Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. A gas-ventilator, comprising a casing designed to be seated in the ground and having a perforated or grating top extended above the ground, open pipes extended from opposite sides of said casing within the ground, and open-ended branch pipes extended from the opposite sides of said first-named pipes, sub stantially as specified.
2. A gas-ventilator, comprising a casing designed to be placed in the ground and having an open-work top, open-ended pipes extended from opposite sides of said casing within the ground, the said pipes being inclined downward from the casing, and open-ended downwardly-inclined branch pipes extending from opposite sides of said first-n amed pipes, substantially as specified.
3. A gas-ventilator, comprising a casing I00 adapted to be placed in the ground below a pavement and having a perforated top portion designed to extend through the pavement, long open-ended pipes extended from opposite sides of said casing within the In testimony whereof I have signed my ground, branch pipes extended from the firstname to this specification in the presence of named pipes, short pipes extended from optwo subscribing Witnesses.
posite sides of the casing and near the upper MILTON CHRISTOPHER HENLEY. 5 portion thereof Within the ground, and short Witnesses:
branch pipes extended from the lower port-ion JAMES F. FLYNN,
of said casing, substantially as specified. ROBERT J. MOKEAN.
