Abstract
A poultry brooder pilot burner is provided wherein a pilot body removably mounts onto a mounting and attachment stud under pressure of a spring washer. Inwardly projecting pins traverse flat areas of the mounting stud to enter a circumferential channel and, upon rotating the pilot body, engage detents under pressure of the spring washer to secure the removable pilot body in place. A safety circuit thermocouple is disposed above and to the side of the pilot burner such that the thermocouple detects only such pilot flame as is capable of igniting the main gas burner.
Claims36
In a poultry brooder including a main gas burner, the improvement comprising a pilot burner having:
- mounting plate means secured to said brooder;
- orifice holder means for receiving and supporting an orifice, said orifice holder means being configured and dimensioned to be connected to a gas source;
- a cylindrical pilot burner mounting stud attached to said mounting plate means, said mounting stud having an annular channel and being configured and dimensioned to engage and support said orifice holder means such that said orifice is exposed;
- a pilot body removably attached to said mounting stud, said pilot body having at least one inwardly projecting mounting pin to engage said mounting stud annular channel, said removable pilot body being disposed over said orifice when attached to said mounting stud and extending horizontally adjacent to the main gas burner.
