DEVICES AND METHODS FOR A MECHANICAL AUTOMATIC SHUT-OFF TO FLUID RESERVOIRS
First Claim
1. An automatic fluid shut off device, comprising:
- a float disposed in a fluid catch basin attached to a first end of a rod movable in a direction of rising fluid in the catch basin;
a second rod end extending to a fluid supply base and terminating adjacent to a restrained latch arm end, the latch arm end configured to be pivotably displaceable upon a force by the second rod end in response to a rising fluid in the catch basin;
the latch arm pivotably connected to a shut-off valve; and
the shut off valve retained in an open position while the latch arm is restrained, and under a rotational force to close the shut-off valve upon a release of the latch arm in response to the force by the second rod end.

Abstract
Embodiments are provided for an automatic fluid shut off device having a float disposed in a fluid catch basin attached to a first end of a rod movable in a direction of rising fluid in the catch basin; a second rod end extending to a fluid supply base and terminating adjacent to a restrained latch arm end, the latch arm end configured to be pivotably displaceable upon a force by the second rod end in response to a rising fluid in the catch basin; the latch arm pivotably connected to a shut-off valve; and the shut off valve retained in an open position while the latch arm is restrained, and under a rotational force to close the shut-off valve upon a release of the latch arm in response to the force by the second rod end. The latch arm can be restrained by a latch arm retention notch extending downward and inward.

10. A method to shut off a water supply, comprising the steps of:
-
providing a first force in response to unanticipated presence of a fluid; displacing a restrained latch arm connected to a shut-off valve handle past a stop in response to the first force; rotating the shut-off valve connected to a fluid supply by a second force in response to a latch arm displacement beyond a release point. - View Dependent Claims (11, 12, 13)
