Ballcock assembly

A ballcock assembly for controlling the supply of liquid to a liquid storage tank comprising,

• an upright standpipe for conveying liquid under pressure to said storage tank,
• valve means on said standpipe at the upper end thereof operable to control the delivery of liquid to said tank, said valve means including a housing, a valve seat, and a valve element movable in a downward direction to an opened position against the flow of liquid flowing through said standpipe and movable in an upward direction to a closed position against said seat,
• a float unit surrounding said standpipe and movable vertically in response to changes in the level of liquid in said tank, and
• linkage means connected to said housing, to said float unit and to said valve element for moving said valve element essentially vertically between its opened and closed positions so that a vertical change in the level of liquid in said tank enables the vertical movement of said float unit to be transmitted to said valve element, said linkage means translating the downward movement of said float unit to said valve element to move it downwardly to said opened position when the level of liquid in said tank drops below a predetermined level,
• said linkage means including a valve actuating member pivotally mounted on said housing and operatively connected to said valve element, said valve actuating member including a pair of side-by-side arm members resiliently movable in directions toward and away from each other, mounting means on said arm members engageable with said housing, said arm members being displaced in one direction so that the resilient return movement of said arm members in the opposite direction causes the mounting means thereon to engage said housing to pivotally mount said valve actuating member on said housing.

A ballcock valve assembly for controlling the supply of liquid to a liquid storage tank comprising,

• a standpipe through which liquid is conveyed to said storage tank,
• valve means on said standpipe for controlling the rate of flow of liquid through said standpipe, said valve means including a housing, a valve seat, and a valve element,
• an elongated valve-actuating member pivotally connected to said housing and movable in an arc toward and away from said standpipe,
• said valve actuating member being connected to said valve element and arranged so that the pivoted position of said valve actuating member relative to said standpipe establishes the rate of flow of liquid through said standpipe, and
• a throttler member adjustably mounted on said valve actuating member for engagement with said housing to terminate the closing arc movement of said valve actuating member toward said standpipe,
• said throttler member being slidable in directions extending longitudinally along said valve actuating member so that the adjusted longitudinal position of said throttler member on said valve actuating member determines the position of said valve-actuating member at which its closing arc movement toward said standpipe is terminated to establish a selected rate of flow of liquid through said standpipe.

A ballcock valve assembly for controlling the supply of liquid to a liquid storage tank comprising,

• a standpipe through which liquid is conveyed to said storage tank,
• valve means on said standpipe for controlling the rate of flow of liquid through said standpipe, said valve means including a housing, a valve seat, and a valve element,
• an elongated valve-actuating member pivotally mounted on said housing and operatively connected to said valve element for opening and closing said valve means, said valve-actuating member being pivotally movable for varying the maximum opening of said valve means, the rate of flow of liquid through said standpipe being dependent upon the position of said valve-actuating member,
• stop means for terminating movement of said valve actuating member at a desired position when said valve actuating member is moved in a direction opening said valve means, and
• a throttler member adjustably mounted on said valve actuating member for engagement with said stop means, said throttler member being slidable in directions extending longitudinally along said valve actuating member so that the selected adjusted position of said throttler member on said valve actuating member determines the position at which the movement of said valve actuating member is terminated to establish a selected rate of flow of liquid through said standpipe.

A ballcock valve assembly for controlling the supply of liquid to a liquid storage tank comprising,

• a standpipe having an upright axis through which liquid is conveyed to said storage tank,
• valve means on said standpipe for controlling the rate of flow of liquid through said standpipe, said valve means including a housing, a valve seat, and a valve element,
• an elongated valve actuating ember pivotally mounted on said housing and operatively connected to said valve element for opening and closing said valve means, said valve actuating member being pivotally movable for varying the maximum opening of said valve means, the rate of flow of liquid through said standpipe being dependent upon the position of said valve actuating member,
• stop means on said standpipe for terminating pivotal movement of said valve actuating member at a desired position when said valve actuating member is moved in a direction opening said valve means, and
• a throttler member adjutably mounted on said valve actuating member for engagement with said stop means, said throttler member being adjustably movable on the valve actuating member to selected longitudinal positions to terminate pivotal movement of said valve actuating member at different pivotal positions of the latter so as to vary the maximum opening of said valve means, said throttler member being movable in directions extending longitudinally of said valve actuating member and essentially radially of said upright standpipe axis so that the selected adjusted position of said throttler member on said valve actuating member determines the position at which the movement of said valve actuating member is terminated to establish a selected rate of flow of liquid through said standpipe,
• said valve actuating member including a pair of side-by-side arm members resiliently movable toward and away from each other, said throttler member being positioned between and in engagement with said arm members for back and forth longitudinal movement thereon.

A ballcock valve assembly for controlling the supply of liquid to a liquid storage tank comprising,

• a standpipe for conveying liquid to said tank,
• valve means on said standpipe at the upper end thereof, said valve means including a housing, a valve seat, and a valve element,
• a valve actuating member pivotally mounted on said housing and operably connected to said valve element for opening and closing the valve means,
• a float unit of fixed volume and weight surrounding said standpipe and movable vertically in response to changes in the level of liquid in said storage tank, and
• connecting means being pivotally and releasably connected to both said float unit and said valve actuating member to transmit the vertical movement of said float unit to said valve actuating member, said connecting means comprising a vertical base portion, means forming a plurality of sockets on said base portion, said sockets each having an access opening and being positioned in a series longitudinally of said base portion, pin means on said valve actuating member and on said float unit, each of said pin means being horizontal and having a cross sectional area slightly larger than the access opening of each of said sockets to enable each of said pin means to be snap-fitted into a selected socket, said pin means on said valve actuating member and on said float unit being snap-fitted into selective ones of said sockets so as to limit rotation of said float unit with respect to said standpipe and to establish a predetermined distance between said valve actuating member and said float unit, the level of liquid in said tank at which said valve means is actuated being dependent on the vertical distance between said valve actuating member and said float unit.
