as burning in the open is controlled to a great extent
by the weather and burning in the open is restricted to a 40

It is the main object of this invention to provide an
incinerator which will provide a means whereby all un
wanted combustible trash may be conveniently burned
in a safe manner and in a manner which will be ap
proved by local community rulings.
These together with other objects and advantages which
will become subsequently apparent reside in the details
of construction and operation as more fully hereinafter
described and claimed, reference being had to the ac
companying drawings forming a part hereof, wherein like
45 numerals refer to like parts throughout, and in which:

A further object of this invention, in accordance with
the preceding object, is to provide an incinerator which
may be utilized to burn combustible trash during all types
