Ornamental-flame burner

Abstract

A burner includes a plurality of end nipples and at least one jet supported by and protruding outwardly from each end nipple. The end nipples and the jets are brass. Each end nipple includes a first end that is threaded and a second end that is closed. Each end nipple includes a wall extending from the first end to the second end and including a bore extending through the first end to the second end. Each end nipple includes a threaded hole extending through the wall to the bore. The first end of the end nipple, the second end of the end nipple, and the wall of the end nipple are unitary. Each jet includes a threaded portion threadedly engaged with the threaded hole and a fuel combustion outlet spaced from the threaded portion. Each jet includes a barrel extending from the fuel combustion outlet toward the threaded portion. The barrel has a larger outer diameter than the threaded portion.
