Serial No. 509,063, ñled November 5, 1943, issued
December 25, 1945, as PatentNo, 2,391,382.
The present invention relates to burners and
has for its main object the provision of a burner
constructed entirely of glass within which elec

of the “pyrex” type, which does not crack when
under the inñuence of a high temperature.
A plurality of transverse openings I5 is made
in plate IG, in a spaced relation, transversely of
the body of plate I (I and between the several
strands of coil I2, for the purpose of providing
draft through said plate I0.
When said plate I0 is placed upon a smooth
