HYDHANT COCK.
APPLICATION mm JAN. 9. 1918.
Patented May 20, 1919.
WILLIAM VOLKHARDT, 0F STAPLETON, NEW YORK.
HYDRANT-GOCK.
Specification of Letters Patent.
Patented May 20, 1919.
Application filed January 19, 1918. Serial No. 212,677.
To all whom it may concern:
Be it known that I, WILLIAM VOLKHARDT, a citizen of the United States, residing at Stapleton, in the county of Richmond and State of New York, have invented a new and useful Hydrant-Cock, of which the following is a specification.
This invention relates to hydrant cocks.
The form of hydrant cock heretofore most generally used is provided with a single waste hole in the center of the key which, when turned in one direction, will permit water to drain from the hydrant but which, if turned against the pressure, will waste water. In the ordinarv form of hydrant cock it is also customary to employ a stop and a stop pin for the purpose of preventing the key from being turned in the wrong direction. It has been found in practice that the stop pin is often broken off when the key is turned in the wrong direction with the result that the water from the main is wasted through the cock and the water in the hydrant is not drawn 011'.
One of the objects of the present invention is to provide a hydrant cock that can be turned either to the right or to the left and which has an arrangement of waste holes cooperating with a drain canal who-reby it becomes unnecessary to utilize a stop of any kind and by turning the valve in either direction to cut off communication between the main and the hydrant, leakage of water from the main is prevented and drainage of the hydrant is secured.
With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.
In the accompanying drawings the preferred forms of the invention have been shown.
In said drawings:-
Figure 1 is a vertical section through a waste cock embodying the present improvements, the same being shown adjusted to establish communication between the main and the hydrant.
Fig. 2 is a section on line 2-2 of Fig. 1.
Fig. 3 is a section through a modified form of hydrant cock.
Referring to the figures by characters of reference 1. designates the casing of the cock the same, being provided with a tapered key seat 2 and having a fluid inlet 3 and a fluid outlet 4 at opposite sides of the seat 2. A hollow tapered key 5 is mounted for rotation to the right or to the left within the casing and fits snugly on its seat, this key being provided at diametrically opposed points with openings 6 adapted to register with the inlet 3 and the outlet 4 when the key is adjusted to one position and to be moved out of register with the inlet and outlet when the key is brought to its other position. A broadened drain canal '7 is formed'in one wall of the outlet 4 beyond the openings 6 and formed within the key 5 at diametrically opposedv points are waste holes .8 either of which is adapted to be brought into communication with the canal 7 when the openings 6 are moved out of register with the inlet 3 and the outlet 4. The casing 1 is provided with the usual vent opening 9 with which either of the openings 6 registers when the key is turned to closed position.
It will be noted that the key 5 can be rotated freely in either direction. When water is to be admitted to a hydrant from a main, the key is turned to the position shown in Fig. 1 so that water entering the inlet 3 will pass through the key and to the outlet 4 and thence to the hydrant. With the key thus located the waste holes 6 are closed at their outer ends by the wall of the key seat. The waste opening 9 is also closed by a portion of the key. By turning the key out of 1ts open position, however, rotating it in either direction, the openings 6 will gradually move out of register with the inlet 3 and the outlet 4 respectively and one of the openings will move into communication with the vent opening 9. Just as the openings 6 close while the key is being brought to its proper position to shut off the flow of Water to the hydrant, one of the waste holes 8 comes into communication with the drain canal 7. Consequently while the flow of water from the inlet 3 to the outlet 4 is cut off, the contents of the hydrant and of the outlet 4 will be free to flow outwardly through the canal 7 into the hole 8 communicating therewith and thence into the key 5 and out through one of the openings 6 and the vent 9.
From the foregoing it will be apparent that the Water will be properly cut at? and the hydrant thoroughly drained whether the key is turned to the right or to the left and as soon as the water is cut oil from the hydrant said hydrant is placed in communication with the vent 9. is no danger of the main being placed in communication With the vent 9 or of Water being retained within the hydrant and the outlet 4 where it is likely to freeze and cause damage.
Instead of providing the drain canal in the upper portion of the valve casing 1, the same can be located in the bottom portion as indicated at 7 in Fig. 3. In this latter event the waste holes 8 are formed in diametrically opposed portions of the key 5 close to the bottom thereof. The-operation is the same in this modified structure v however, as. in the structure shown in Figs. 1 and 2.v
Importance is attached to the use of the drain canal and the diametrically opposed waste holes as it is thereby possible to eliminate the stop and secure proper operation of the cock under all conditions.
Consequently there.
\Vhat is claimed is A hydrant cock having an inlet, an outlet and a tapered key seat between the inlet and outlet, there being a drain canal in the wall of the outlet and in the large end portion of the tapered key seat, a hollow, tapered.
key mounted for rotation in either direction upon the key seat and having diametrically opposed openings movable into register with the inlet and outlet, there being a vent within the casing adapted to register with one of said openings when the key is moved to closed position, there being diametrically opposed waste holes within the large end portion of the key and opening into the space within the key either of said holes being ROBERT J. MEEHAN.
