Specification of Letters Patent.
Patented April 16, 1907.
Application filed September 20, 1906. Serial No. 335,416.
Tea/ll whom, it may concern:
Be it known that I, ABRAHAM LINCOLN DOW, a citizen of the United States, and a resident of Lyons, in the county of Boulder and State of Colorado, have invented a new and Improved Valve, of which the following is a full, clear, and exact description.
This invention relates to certain improvements in valves, and especially in hydrantvalves, whereby the valve and valve-seat may be removed from the casing without disconnecting the latter should it become necessary to repair or replace any of the working parts. This is of particular value around hydrant-valves, which are usually so located that it is very diflicult to get at the valve to repair it.
Reference is to be had to the accompanying drawing, which illustrates one embodiment of my invention and in which the single figure shown is a central longitudinal section through the same.
The valve-casing 1' is preferably substantially cylindrical in cross-section and is provided with an inwardly-directed flange 2 adjacent its lower end and adapted to engage with an inner tube to separate the casing into two compartments. The lower end of the casing is provided with a fluid-inlet connection 3, while the cylindrical body portion at a point above the inwardly-directed flange .2 is provided with an outlet-pipe connection 4..
The upper end of the casing has a screwthreaded opening into which is inserted the tube 5, which latter is conical at its lower end and adapted to fit against the beveled edge of the flange 2. The tube is provided with a plurality of perforations along its length and between the top of the casing and the flange 2, whereby liquid may freely pass from the interior to the exterior of the tube. The upper end of the tube may be either provided with a hexagonal nut or with upwardly-projecting lugs 7, whereby a suitable wrench may be applied to screw the tube in place and force it tightly against the tapered edge of the flange 2, which constitutes a seat for the conical end of the tube.
The lower end of the tube 5 is cut perfectly even and constitutes a valve-seat 8, against which a plate 9, constituting the valve, is adapted to be forced. The plate 9 is provided with a downwardly-extending collar 10, into which is screw-threaded the lower end of a valve-stem 11, extending throughout the length of the tube. .The
valve-stem 11 is screw-threaded through an opening in the outer end of the tube 5 and at its outer end is provided with means whereby it may be rotated to force it into and out of the tube, and thus force the valve toward or away from the valve-seat. The upper end of the valve-stem is provided with a passage 12, extending longitudinally thereof and having the ends terminating at points one of which is above and the other of which is below the closed end of the tube 5 when the valve 9 is forced against its seat. It will thus be noted that the passage 12 is always open when the valve 9 is closed, but as the latter is opened the upper end of the passage 12 is closed by the end of the tube 5 to prevent the escape of fluid through this passage when the main valve 9 is open.
In case anything happens to the valve or valve-seat to revent a close fit being secured and causing t he valve to leak or in case the arts become worn so that it is deemed advisable to replace them the tube 5 may be screwed out of the casing, and as it carries the valve-stem and valve with it it will be seen that all the working parts may be readily disclosed to view and inspected at leisure.
When the tube is in place, no liquid can pass the tapered seat, but can only escape when the valve 9 is opened by the turning of the valve-stem 11. When the valve and valve-stemare removed by the removal of the tube 5, the valve-stem and its support are also removed, and by turning the valvestem after the tube fit of the valve with easily adjusted.
The passage 12 permits the escape of fluid from the tube 5 after the valve is closed, thus avoiding danger due to high pressure in the valve-casing.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In combination, a valve-casing having inlet and outlet ports, one of which is located at the end of the casing and the other of which is located at the side of the casing, an inwardly-directed partition at the end of the casing having the port, the inner surface of the partition being beveled, a tube screwthreaded to the casing at the opposite end thereof and adapted to contact with the beveled surface of said inwardly-directed flange, a valve adapted to close the inner end i of the tube, and a valve-stem carrying said the valve-seat may be has been removed thevalve and extending outward through the tube at the opposite end thereof and having a passage, the ends of which communicate with the interior of the tube and with the outside thereof when the valve is closed.
2. In combination, a substantially cylindrical valve-casing having an inlet-port and an outlet-port, one of which is located at the end of the casing and the other of which is located at the side of the casing, an inwardlydirected flange adjacent the end of the casing having the inlet-port, the inner edge of said flange being tapered, a perforated tube screw-threaded into the opposite end of the casing and having the inner end thereof conical and adapted to be forced into contact with the tapered edge of the inwardly-directed flange, a valve adapted to close the in- ABRAHAM L. now.
