6 Claims. (Cl. 126-140)
This invention relates to heating apparatus for
houses, and has for one object to provide a de
sirable, efficient and economical heater in which
_ wood or other fuel can be burned in an open ?re,
as in an ordinary open ?replace, but which obvi
ates the necessity for the usual expensive, built
in masonry ?replace and chimney.
Other objects of the invention are to produce
With the above and other objects and advan
tages in view, which will hereinafter appear, pre
ferred embodiments of my invention, disclosed
in the accompanying drawings, are hereinafter
described and the novel features of the invention
are set forth in the appended claims.
