PETER KELLER, OF CHICAGO, ILLINOIS.
Specification of Letters Patent.
Patented June 29, 1915.
Application filed May 14, 1914. Serial N 0. 838,450.
To all whom it may concern:
Be it known that I, PETER KELLER, a citizen of the United States, residing at the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Gas-Pressure Regulators, of which the following is a specification.
The object thereof is to provide a simple, cheap and convenient apparatus by which the pressure of illuminating gas may be automatically regulated and controlled and by which gas may be taken from the delivery pipes at varying pressures and delivered to the house pipes, or to the particular point of consumption as, for instance, a gas stove at constant pressure.
My device further is of such a character that the standard unions used for detachable connecting piping may be used as a casing to inclose the device and in most instances to become an actual part thereof.
The principles of my invention are illustrated in the drawings, in which Figure 1 is a central sectional view of my device as used in connection with a standard union. Fig. 2, is a front end elevation of my device detached.
Referring to said drawings; 1 is a delivery pipe from which the gas passes into my device, 2 represents an ordinary union, and 3, my device, which consists of a tapered shell or tube,4and having an annular flange, 5 located toward or tube. A plate or partition 6 having a central opening, 7 is secured in the rear end of said shell 4 and serves to cut down the flow of the gas from the service pipe 1.
I The forward end of the shell 4 is provided with internal threads 8, and a plug 9, having external threads 10, adapted to screw into the forward end of the shell 4, and having a slot or groove 11, by which said plug may be properly adjusted by means of a screw driver or any suitable tool; and also having a central opening 12, which will permit of a direct flow of gas through the shell 4 when the pressure in the delivery pipe is low. The forward portion of the shell 4 has a series of holes, 13 preferably staggered, as shown in Fig. 1 of the drawing; a ball 14 is inclosed in said shell to serve as a valve or check.
Copies. of this patent may be obtained for five cents each, by addressi the rear end of said shell In o eration under very low pressure in the delivery pipe the ball 14 will travel down the incline of the inner wall of the shell 4, until it comes in contact with the end partition 6; as the pressure increases the ball 14 will travel forward allowing the gas to pass around its surface between the tapered walls of the shell 4 and out through the openings 13 and through the opening 12 of the plug 9; when the pressure becomes too great the ball 14 will be forced forward until the opening 12 in the plug is entirely closed and the openings 13 form the only outlet. If less flow of gas under said conditions is desired, the plug 9 may be adjusted so as to allow only a portion of the holes 13 in the shell 4 to act as the outlet, as shown in Fig. 1 of the drawing. And it will be readily understood that the farther into the shell 4 the plug 9 is screwed, the more the outlet of the gas through the openings 13 is restricted.
While I have shown my device as being adapted to a horizontal connection, the same will work equally well in a vertical position.
I claim and desire to secure by Letters Patent 1. In combination with a pipe union; a gas pressure regulator having a shell provided with an annular flange, a series of holes around the forward portion of said shell, an adjustable plug in the front end thereof, a wall or plate in the rear end thereof, and a ball to operate within said shell.
2. In combination with a pipe union; a gas pressure regulator having a shell provided with an annular flange near its rear end, a rear end wall or plate provided with a central opening, the forward portion of the shell, a plug with a central opening adapted to screw into the forward opening of the shell and a ball to operate therein.
3. A gas pressure regulator having a tapered shell, provided with an annular flange, a series of holes preferably staggered around said shell, a plug in the front end thereof, a perforated plate in the rear end thereof, and a ball to operate within said shell.
