UNUSED STATES FATE@ FFCE.
BALL-COCK.
To all whom it may concern:
Be it known that l, CHARLES B. lllr-irrivnr, a citizen of the United States, residing at Hyde Park, in the county of Norfolk and State of Massachusetts, have invented new and useful mprovements in Ball-Cocks, of which the following is a specification.
rlhis invention relates to improvements in ball cocks, and the objectis to prevent the practically continuous leakage of water which usually occurs between the valve and its seat after the ball float has reached its highest level.
rlhe invention consists in the no-vel features of construction and in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims.
Referring` to the drawings: Figure 1 is a longitudinal vertical sectional view of a ball cock embodying my invention, the same being shown in its fully opened position. .F 2 is a sectional view similar to Fig. 1 with the exception that the ball cock lever is shown fully raised and the valve closed. Fig. 3 is a detail section showing the ball cock lever just before it has reached its uppermost position and before the valve is entirely closed, the same being held by the latch. Fig. 4 is an enlarged longitudinal sectional view of the plunger.
In the drawings, 8 is a valve casing consisting of a body portion 9 having a spout 10 and an inlet passage 11 where the water is admitted. The valve casing is provided with a seat 17 against which a valve 18 consisting of a stein 19 and disk 2O is adapted to bear. Ar suitable plunger 24 having passages 25 extending longitudinally therethrough and permitting the water to iow from the inlet passage 11 to the seat 17, bears against one end of the valve stem 19 and is encircled by a spring 29 tending to seat the valve 18.
rfhe particular plunger herein shown forms a part of the subject matter of U. S. Letters Patent No. 902,786, dated November 8, 1908, to which reference may be had for its mode of operation, it being understood, however, that any plunger having passages extending longitudinally therethrough may be employed, if desired. Y
8O is a ball float lever to' which, in practice, a ball float will be attached and this lever is supported upon a pivot 84 mounted in ears formed on the casing 8. The
Specification of Letters Patent. Application filed ctober 25, 1309.
v Patented Dec. 20, 1910. Serial No. 524,317.
As the water begins to rise in the tank, the float lever 30 is raised thereby and the roll 48 in swinging from the position shown in Fig. 1 to the position shown in Fig. 3, permits the pin 31 and valve 18 to move toward the left under the influence of the spring 29 and the water pressure until said valve is nearly closed, at which time the roll engages the roll 51 slightly above the center of the latter roll. rllhe latch 52 now acts through the rolls 50 and 51 to lock the pin 31 and valve 18 against further movement toward the left. Continued upward movement of the float lever 30 results in the roll 48 being carried out of engagement with the plate 49 and finally said lever acts to lift the latch 52 until the center of the roll 51 has risen very slight-ly above the center of the roll 50,thereby freeing the pin 31 and valve 18 and allowing the same to be carried toward the left under the influence of the spring 29 and the -water pressure until said valve contacts with its seat, as shown in Fig. 2. It will be observed, however, that the plate 49 is still out of engagement with the roll 48 and, therefore, the float lever 30 and roll 48 do not interfere with the water pressure and spring pressure holding the valve 18 rmly in Contact with its seat and, therefore, there can be no leakage. The final position of the latch 52 is shown in Fig. 2.
Having thus described my invention, what l claim and desire by Letters Patent to secure is:
1. A ball cock having, in combination, a casing having a valve seat therein, a valve adapted to be normally held against said seat by pressure, a pivoted float lever adapted in falling to move said valve away from l said seat and in rising to allow said valve l to be carried toward said seat by the pressure, and means to stop said valve near the end of its closing movement, said float lever being adapted to subsequently actuate said means to allow said vvalve to become seated unrestrained by said float lever.
2. A ball cock having, in combination, a casing having a valve seattherein, a valve adapted to be normally held against said seat by pressure, a pivoted float lever adapted in falling to move said valve away from said seat and in rising to allow said valve to be carried toward said seat by the pressure, and a latch adapted to stop said valve near the end of its closing movement, said float lever being adapted to subsequently render said latch inoperative thereby to allow said valve to become seated unrestrained by said float lever.
3. A ball cock having, in combination, a casing having a valve seat therein, a valve adapted to be normally held against said seat by pressure, a pivoted floatlever adapted in falling to move said valve away from said seat and in rising to allow said valve to be carried toward said seat by the pressure, means acting on said valve and projecting outwardly from said casing, a latch, and a roll journaled on said latch and adapted to engage said means to stop said valve near the end of its closing movement, said float lever being adapted to subsequently render said latch inoperative thereby to allow said valve to become seated unrestrained by said float lever.
4. A ball cock having, in combination, a casing having a valve seat therein, a valve adapted to be normally held against said seat by pressure, a pivoted float lever adapted in falling to move said valve away from said seat and in rising to allow said valve to be carried toward said seat by the pressure, a pin acting on said valve and projecting outwardly from said casing, a roll journaled on said pin, a latch, and a roll journaled on said latch and adapted to engage the hist-mentioned roll to stop said valve near the end of its closing movement, said float lever being adapted to subsequently trip said latch thereby to allow said valve to become seated unrestrained by said iioat lever.
5. A ball cock having, in combination, a casing having a valve seat therein, a valve adapted to be normally held against said seat by pressure, a pivoted float lever adapted in falling to move said valve away from said seat and in rising to allow said valve to be carried toward said seat by the pressure, a pin acting' on said valve, and projecting outwardly from said casing, a roll journaled on said lever and adapted to engage said pin, a roll journaled on said pin, a latch, and a roll journaled on said latch and adapted to engage the second-mentioned roll to stop said valve near the end of its closing movement whereby the third-men tioned roll passes out of engagement with said pin, and said valve is allowed to become seated unrestrained by said float lever.
In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
