JOHN J. MITCHELL, 0F HARRISON, NEW JERSEY.
FITTING FOR VENTS OF SEWER-S.
Specification of Letters Patent.
Application filed May 9, 1910.
Patented July 25, 1911.
Serial No. 560,222.
To all whom it may concern:
Be it known that I, JOHN J. MITGHELL, a citizen of the United States, residing at Harrison, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Fittings for Vents of Sewers and the Like; 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 appertains to make and use the same, reference being had to the accompanying drawings, and to figures of reference marked thereon, which form a part of this specification.
This is an improved fitting for fresh air vents for sewers and the like, in buildings, and is designed to provide a vent which is easily assembled and separated and is provided with a valve which automatically closes on the tendency of a current to flow backward through the vent, which valve is simple in its operation and is cheap in construction, and the simplicity of which insures its operation.
The device also embodies a member containing a receptacle which permits the current of air to pass through the vent, the receptacle being adapted to supply the current with a suitable disinfectant which the receptacle is constructed to hold, and which is provided with means for positively insuring the impregnation of the air passing through the vent with the disinfectant.
The invention is illustrated in the accompanying drawing, in which- Figure 1 is a diagrammatic view showing the attachment of the fitting to a pipe system. Fig. 2 is a vertical, central section of the fitting, and Fig. 3 is a top view of the bottom member of the fitting with the top removed showing the receptacle for the disinfectant.
The device is attached to any suitable place in the pipe system, but is illustrated in Fig. 1 as being mounted on a trap 10 of a sewer or soil pipe 11 which terminates, as at 12, at the roof of a building and acts as the outlet for the air vent, although it is evident that other systems of piping can be utilized, these systems being common and well known in the art. The inlet pipe 13 admits the air that passes down through the fitting and then through the pipe 11 and out of the end 12, this part of the system without the fitting being old and in common use at present. The fittin can be made up in a number of difierent Forms and as sembled in different ways, but I prefer to make it of two members 14 and 15 which are placed together and then calked as usual,
the member 15 and the member 14: having body portion of the member 15 contains a receptacle or vessel 18 which is made of any suitable material, but I prefer to make it of glass, the vessel having an outer wall 19 and an inner wall 20, connected by the bottom 20*, to form an annular chamber to contain a suitable disinfectant 22, and the inner wall forms a passage 23 for air, the passage being preferably made the same size as the soil pipe so as not to interrupt or impede in any way the steady flow or current of air. The annular chamber of the receptacle 18 has an open top so that the disinfectant can evaporate into the air passing through the fitting, but other means can be employed for slowly permitting the exit of the disinfectant into the fitting or soil pipe, as will be understood.
The upper member 14: that fits in the lower member 15 has its end 16 arranged to receive the inlet pipe 13 and provide room for calking, although this is not essential, and equivalent structures can be made for connecting these pipes, but I prefer to have the end of the inlet pipe 13 terminate directly above a bar 24; which has its ends in recesses 25, the bar acting to support a bolt 26 which depends from the bar, the bolt having a suitable head 27 on which is normally suspended a valve 28 which is conical and slides easily on the bolt 26 by means of a perforation at its apex. The upper member, on the inner side of the portion 29 where it con tracts, is formed into a valve seat 30 against which the valve 28 is adapted to be forced to make an air tight oint when there is the slightest tendency of the current of air going in the reverse direction through the fitting and consequently through the system. The valve 28 is likewise forced shut in case of any stoppage in the pipes and if there is plenishing the receptacle 18 with a supply of disinfectant.
Having thus described my invention, what I claim is 1. A fitting for vents comprising an upper and a lower member, each of the members having an opening in its outer end, a recep tacle 1n the lower member, the receptacle,
having a passage through it and having an annular chamber, a bolt, means for suspending the bolt in the upper member, a head on the lower end of the bolt, and a valve sliding 011 the bolt and adapted to be normally suspended on the head of the bolt the upper member having a valve seat therein against which the valve is adapted to be forced by a reverse current.
2. A fitting for vents comprising an upper and a lower member, each of the members having an opening in its outer end, a receptacle in the lower member, the receptacle having a passage through it and having an annular chamber, the upper member having recesses on the inner wall of the opening in its end, a bar arranged to be seated in the recesses, a bolt suspended from the bar, a head on the bolt, a valve adapted to slide on the bolt and normally suspend it on the head, and a valve seat within the casing against which the valve is adapted to be forced by reverse current.
8. A fitting for vents comprising an upper and a lower member, each of the members having an opening in its outer end, a receptacle in the lower member, the receptacle having a passage through it and having an annular chamber, the upper member having recesses on the inner wall of the opening in its end, a bar arranged to be seated in the recesses, a bolt suspended from the bar, a head on the bolt, a valve adapted to slide on the bolt and normally suspend it on the head, a valve seat within the casing against which the valve is adapted to be forced by reverse current, the upper member having an opening therein so disposed as to permit filling of the receptacle in the lower member, and a closure for the opening.
In testimony, that I claim the foregoing, I have hereunto set my hand this 3rd day of May 1910.
JOHN J. MITCHELL.
