COMPLETE SPECIFICATION.
An Improved Heating Apparatus.
I, MARY ROE, of Dayton Township, in the County of Hennepin and State of
Minnesota, United States of America, Gentlewoman, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to improvements in heating apparatus in which drums
operate in conjunction with obstructions in chimneys; and the objects of my
invention are, first, to obtain warmth by the use of the product of combustion
in its passage to the open air; second, to combine in a heating drum good
heating capacity with simplicity of construction, and, third, to avoid complexities
that would induce the accumulation of soot and render its perfect expulsion
impossible. I attain these objects by the mechanism illustrated in the accompanying
drawings, in which-
Figure 1 is a view of the drum placed in connection with the chimney;
Fig. 2, a vertical sectional view of said drum, and
Fig. 3 a view of a horizontal section on the line shown in Fig. 2.
A is the drum; B, section of chimney; C, obstruction in chimney; D, section
of pipe connecting chimney B with drum A near its base; E, section of pipe con-
necting chimney B with drum A near its top. Of these the construction of the
drum is all that is claimed.
Drum A consists of two cylinders, one within the other. The inner cylinder f
is open its entire length. A portion of the outer cylinder g, of the same length
as cylinder f, is removed, giving space for a cavity in the front part of the drum.
The lines of cylinders and g are parallel until each side of cylinder as it nears
the front rounds outward in the form of a half circle and is attached to the corre-
sponding side of cylinder y. Cylinder is finished with heads at both ends, the
heads aforesaid being attached to the portions of cylinder y below and above the
cavity, and thus finished, it encloses the cavity. The heads of cylinder g are
removable. The removable heads of cylinder g are held in place by removable
rods jj, which pass through the upper head downward through the inner part of
the drum, thence through the lower head into nuts, the lower euds of said rods
being threaded for the reception of nuts. The upper ends of the rods jj are
finished with handles to prevent their turning when the nuts aforesaid are being
adjusted. Caps encircle the rods below the handles aforesaid, pressing down-
ward upon the upper head K of cylinder g and preventing the escape of gas from
the drum. At the back side and near the end are holes for the admittance of
pipes. The advantages of this drum are that, while it allows the hot air to pass
below and above a cavity, it has no acute angles and no interior complications, thus
presenting the greatest possible surface from which to radiate heat compatible with
simplicity of construction and also the least possible tendency to the accumulation
of soot and the greatest possible facilities for its expulsion.
I am aware that prior to my invention heating drums have been made with
removable heads; also, that standards of heating apparatus have been attached to
removable frames, and that removable rods have been used to hold the heads of
cylinders in place. I therefore do not claim such combinations, broadly.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. The combination in a heating drum of removable heads held in place he

page_text: removable rods encircled by caps which press downward upon the upper head
of the drum, substantially as set forth, for the purpose specified.
2. The combination, in a heating drum, of removable rods which pass downward
through the upper head and inner part of the drum, thence through the lower
head and removable section (to which standards are to be attached) into nuts, said
rods being encircled by caps which press downward upon the upper head of the
drum, all substantially as shown, for the purpose specified.
3. The combination, in a heating drum, of hot air spaces below and above a
cavity, the inner and outer cylinders of said drum uniting on either side of the
cavity in the form of a half circle, all substantially as described, for the purpose
specified.
