Semi-automatic gas pilot orifice clean-out device

An actuating mechanism for cleaning out the exit of a gas pilot orifice of a T-shaped gas pilot of an agricultural brooder or other appliance that utilizes a gas pilot as an ignition source, the T-shaped gas pilot being formed of a T-tube having a inlet port, and exit port to which the pilot orifice is attached and a gas pilot opening adapted to receive the actuating mechanism, comprising:

• a plunger rod having a free end and a secured end;
• a clean-out pin mounted to the free end of the plunger rod, the pin having a diameter sized to allow it to pass through the pilot orifice;
• and
• a push button assembly attached to the secured end of the plunger, the push button assembly being comprised of:
• a push button nut for securing the assembly to the gas pilot opening;
• a push button mounted within the push button nut, the push button having at least three annular grooves with an O-ring positioned in each groove in order to provide a gas-tight seal and having an internal recess for receiving the secured end of the plunger rod, the plunger rod being secured within the recess;
• and
• a spring located around the plunger rod and substantially between the push button and the opening, so that when the spring is extended gas flows through the gas pilot and when the spring is compressed the clean-out pin passes through the gas pilot orifice.

A semi-automatic gas pilot orifice clean-out device for cleaning a gas pilot orifice of an agricultural brooder or other appliance having a gas pilot, a gas supply, a gas supply line connecting the gas supply to the gas pilot, the clean-out device comprising:

• a T-shaped tube having an inlet port adapted for attachment to the gas supply line, an exit port and an actuating mechanism opening, the inlet and exit port being in flow-through communication and the opening being coaxial with and opposite the exit port;
• a section of tubing attached to the exit port, the section of tubing bearing an orifice holder opposite the exit port and having a gas pilot orifice secured in the orifice holder;
• an actuating mechanism sized and mounted within the device so as to provide an optimized internal flow path allowing unrestricted flow of gas through the device when the mechanism is not actuated, the actuating mechanism being comprised of:
• a plunger rod having a free end and a secured end;
• a clean-out pin mounted to the free end of the plunger rod, the pin having a diameter sized to allow it to pass through the pilot orifice;
• and
• a push button assembly attached to the secured end of the plunger, the push button assembly being comprised of:
• a push button nut for securing the assembly to the gas pilot opening;
• a push button mounted within the push button nut, the push button having a gas-tight seal and to prevent entry of contaminants and debris into the gas pilot;
• and
• a spring located around the plunger and substantially between the push button and the opening of the pilot.

A gas pilot with semi-automatic clean-out device, comprising:

• a gas pilot comprised of a tubular housing having a longitudinal length and two ends, a gas orifice with an orifice exit port, the gas orifice being located at one end of the housing, a gas pilot opening at the other end of the housing, the opening being configure and adapted to receiving an actuating mechanism, a gas inlet port configured for flow-through attachment to a gas supply, an actuating mechanism coaxially located within the housing, the actuating mechanism being comprised of:
• a plunger rod having a free end and a secured end;
• a clean-out pin mounted to the free end of the plunger rod, the pin having a diameter sized to allow it to pass through the pilot orifice;
• and
• a push button assembly attached to the secured end of the plunger, the push button assembly comprising a push button nut for securing the assembly to the gas pilot opening;
• a push button mounted within the push button nut, the push button having a redundant sealing system to provide a gas-tight seal and to prevent entry of contaminants and debris into the gas pilot, the actuating mechanism being actuated by the push button to push the plunger rod in the direction of the gas orifice;
• and a spring for returning the plunger rod to an open position, the spring being located around the plunger and substantially between the push button and the opening of the pilot.
