VALVE FOR DOWN SPOUTS AND THE LIKE.
APPLICATION FILED MN- 30, 1913'.

VALVE FOR DOVN-SPOUTS AND THE LIKE.
Specification of Letters Patent.
Patented Apr. 6, 19151.
Application filed January 30, 1913. Serial No. 745,064
To all whom it may concern.
Be it known that I, CARTER C. ABM- srnone, a citizen of the United States, and a resident of the city ofCincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Valves for Down-Spouts and the like, of which the following is a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification.
The object of my invention is to provide a suitable valve for down spouts which are connected with the sewer to prevent the sewer gas from passing up through the down spout at the same time that free outlet for the gas is provided.
In municipalities where down spouts are required to be connected directly with the sewer, it is also usually required that there shall be no trap to prevent the free escape of sewer gas through the sewer connection, and therefore no trap of the usual construction can be installed, and as a result the gas 2 has ordinarily free outlet through the down spout. This gas has a very injurious eifect on the down spout pipe and in a very short time the gases passing up through the pipe cause rust and decay and the down spout must be removed, which under other conditions would last for many years.
It is to obviate this difficulty and to prevent the sewer gases from escaping through the down spout, and at the same time to provide for the free escape of the gases that my invention is directed, and it consists of that certain novel construction and arrangement of parts to be hereinafter particularly pointed out and claimed.
In the drawings, Figure l is a central vertical section of my improved construction. Fig. 2 is a transverse section, taken through "the center of the barrel. Fig. 3 is a side elevation of my device very much reduced in size.
An ordinary down spout pipe for rain water from the roof is indicated at 1, with sewer connecting pipe 2. At the connection of these two pipes my device is installed, usually at or near the ground. It comprises the cylindrical barrel 3, with one end turned upwardly and provided with a cap 4, preferably screwthreaded thereon.
This cap is provided with a hole 5, for the free escape of sewer gas at all times.
The barrel 3 is formed with a down spout connection 6 and a. sewer connection 7 The barrel is inclined somewhat from the horizontal toward the down spout connection, and in the lower end is formed with a conical seat 8, upon which the ball valve 9 is normally seated, owing to the incline of the barrel, to close the passage into the down spout. A track 10 is provided in the barrel overthe sewer outlet to prevent the ball valve, when moved from its seat, closing the sewer opening. There isthus always a free outlet for the sewer gas through the barrel and opening 5 in the cap. Gas, however, cannot find its way into the down spout as this passageway is closed by the ball valve. The ball valve is of light material, as of hollow rubber or cork, and when rain water descends through the down spout, the ball is pushed away into the upper end of the barrel. If a large volume of water is discharged by the down spout, the ball valve is carried up to close the opening 5, so that the rain water can never escape through the opening 5 in the barrel.
My invention is readily and easily applied to the end of the down spout at the sewer connection.
By removing the cap 4, access may be alboth by gravity and the suction through the P P Having thus described my invention, what I claim as new and desire to secure by Let ters Patent, is
1. In a device of the character specified, a barrel, a down spout, and a sewer pipe connected thereto so as to form a T-joint of which the down spout and the barrel form the branches, the barrel turned up at its free end, with an opening in the free end thereof, a ball valve, a trackway over the sewer pipe connection with the barrel to prevent the ball from seating therein and a valve seat about the down spout connection with the barrel, for said ball.
2. In a device of the character specified, a
barrel, a down spout, and a sewer pipe connected thereto so as to form a T-joint of which the down spout and the barrel form the branches, the barrel turned up at its free end, with an opening in the free end thereof, a ball valve, a trackway over the sewer pipe connection with the barrel 'to prevent the ball from seating therein and a valve seat about the down spout connection with the barrel and about the opening in the free end of the barrel, for said ball.
3. In a device of the character specified, a
barrel portion, a down spout and a sewer pipe, said barrel beingprovided with open ings for the spout and pipe, and having an opening to the outer air, a valve seat about the down spout opening, a ball valve to normally seat thereon, and means for preventing the ball valve from blocking the opening for the sewer pipe, whereby a free outlet is formed for sewer gas through the barrel without permitting the same to enter the down spout.
