Abstract
Generally speaking, a latching valve is easily installed in the path of gas flow on a gas grill. Once a grill is turned on, an automatically activated on/off switch activates a electric timing device, which begins monitoring time. The timing device is adjustable by the user to set the amount of time it will accrue prior to sending power to a latching valve, terminating the gas flow. So, if a gas grill is inadvertently left on, the latching valve will receive power and be closed, saving fuel and preventing a possible hazard. At this point a reset button on the timing device must be pressed to reopen the latching valve. But, if a gas grill is used and shut off prior to that time set by the timing device no action will result from the Gas Grill Propane Monitor.
Claims12
A gas grill propane monitor for monitoring time once a barbeque grill is activated and shutting off the gas source if inadvertently left on longer than the preset allowed time limit comprising:
- means for monitoring time;
- means for resetting a latching valve, directly connected to said means for monitoring time;
- means for setting a time duration
- directly connected to said means for monitoring time;
- means for controlling gas flow, directly wired to said means for monitoring time;
- means for activating a timing device, externally wired to said means for monitoring time;
- and
- means for powering the gas grill propane monitor components, wired to said means for monitoring time.
A gas grill propane monitor for monitoring time once a barbeque grill is activated and shutting off the gas source if inadvertently left on longer than the preset allowed time limit comprising:
- a timing device, for monitoring time;
- a reset switch, for resetting a latching valve, directly connected to said timing device;
- a potentiometer, for setting a time duration directly connected to said timing device;
- a latching valve, for controlling gas flow, directly wired to said timing device;
- an on/off switch, for activating a timing device, externally wired to said timing device;
- and
- a power source, for powering the gas grill propane monitor components, wired to said timing device.
