PROVISIONAL SPECIFICATION.
An Improved Steam or Air Superheater.
MATTHEW MILLER 116 Taylor Street, Glasgow N.B. Physician do hereby declare
the nature of this invention to be as follows:-
My Invention essentially consists in having an iron or other metal hollow vessel
made partly spherical like an ordinary oil pan or still bottom; or cylindrical like an
ordinary horizontal retort, or a modified form of either of those vessels.
In said hollow vessel I place oil, tar or analogous liquid of high vaporizing point;
or lead, tin, zinc or analogous metal of low specific heat and comparative low
liquifying point.
In said hollow vessel I also place a tube or tubes made in the form of a coil or
series of coils, said tube or tubes being wholly or partially immersed in the liquid or
metal with which the hollow vessel is completely or partially filled.
The aforesaid hollow vessel-with its charge of oil or metal and hollow tube or
tubes distributed throughout the oil or metal-I build in an oven, fireplace or flue to
enable its being heated externally.
In superheating the air or steam, said vapour is passed through the aforesaid tubes,
when the liquid or metal, in which the tubes are immersed is heated to the desired
temperature.

COMPLETE SPECIFICATION.
An Improved Steam or Air Superheater.
I, MATTHEW MILLER, of 116 Taylor Street, Glasgow, in the County of Lanark,
North Britian, Physician, 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 which relates to an improved steam or air superheater, essentially
consists in having an iron or other metal hollow vessel made partly spherical like an
ordinary oil pan or still bottom; or cylindrical like an ordinary horizontal retort; or
a modified form of either of these vessels.
In said hollow vessel I place oil, tar, or analogous liquid of high vaporizing point;
or lead, tin, zinc, or analogous metal of low specific heat and comparative low
liquifying point.
In said hollow vessel I also place a tube or tubes made in the form of a coil or series
of coils, the said tube or tubes being wholly or partially immersed in the said liquid
or metal with which the hollow vessel is completely or partially filled.
The aforesaid hollow vessel with its charge of oil or metal and hollow tube or tubes
distributed throughout the oil or metal, I build in an oven, fire-place, or flue to enable
its being heated externally..
In order that my Invention may be properly understood and readily carried into
effect I have hereunto appended one explanatory sheet of drawings, of which A is
the hollow vessel; B the liquid or metal; C the coil of tubes; D the flues; and E
the furnace.
In superheating the air or steam, the said vapour is passed through the coil of
tubes C, when the liquid or metal D in which the tubes Care immersed, is heated to
the desired temperatura

page_text: 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 :-
Superheating air or steam in the manner herein before described and shown on the
accompanying Sheet of Drawings.
