This invention is directed to an improvement in
oil burners, involving a completely portable unit
designed for vaporizing and burning of waste
oils, such as crank-case oil, but equally service
able with other vaporizable fuels.
The burner of this invention is constructed in
two substantially similar parts, capable of being
assembled in burner forming relation or readily
separable for convenient and easy cleaning of
carbon and other deposits, and involving simple
and easily operated mean-s for securing the parts
in burner-forming relation.
An essential object of the invention is the pro
vision of a burner of comparatively small size

The burner is assembled by bringing the
straight edges and webs into contact, »and such
straight edges may, if desired, be formed for
mating cooperation to assist in sealing the junc

One end of each bolt is headed at 9 and the op

connection may be driven with sufficient tight

starting fuel heat, is emitted through all holes

any appropriate metal. The vaporizing cham

and circular in section. The unit is completely
portable and may be readily moved from place to
