Cable actuated remote emergency shut-off system

A system including:

• a handle located proximate a valve and configured to open and close the valve;
• wherein the handle is in a first handle position when the valve is open;
• and
• wherein the handle is in a second handle position when the valve is closed;
• a slot located on one of the valve and the handle, wherein the slot has a closed, elongated arcuate configuration;
• a detent located on the other of the valve and the handle, the detent configured to be received in the slot;
• a guide fixedly connected to the handle;
• an arm moveably connected to the guide, wherein the arm includes a passage configured for insertion of a portion of the guide;
• a channel located on one of the guide or the arm, the channel having opposed first and second ends;
• and
• a projection located on the other of the guide or the arm, the projection configured to be received in the channel;
• wherein moving the projection past a location of the first end of the channel pulls the guide and the handle, thereby moving the handle from the first handle position to the second handle position;
• and
• wherein the projection can be moved toward the second end of the channel while the handle remains in the second position.

A method of operating a system, the system including:

• a valve;
• a handle located proximate the valve that opens and closes the valve;
• wherein the handle is in a first handle position when the valve is open;
• and
• wherein the handle is in a second handle position when the valve is closed;
• a guide connected to the handle;
• an arm connected to the guide;
• a channel located on one of the guide or the arm, the channel having opposed first and second closed ends;
• and
• a projection located on the other of the guide or the arm, the projection configured to be received in the channel;
• the method including:
• moving the projection past a location of the first end of the channel to pull the guide and the handle, thereby moving the handle from the first handle position to the second handle position to close the valve;
• and
• moving the projection toward the second end of the channel while maintaining the second position of the handle and a closed state of the valve.
