PROVISIONAL SPECIFICATION.
Steam Apparatus for Heating Rooms or other Structures.
JOHN ALFRED GROOM Engine Turner 8 Sekforde Street Clerkenwell E.C.
Middlesex do hereby deelare the nature of this invention to be as follows:-
An apparatus for heating purposes by means of confined and condenced steam,
without the steam being alowed to escape but after being condenced is returned into
the cistern and boiler to be again converted into steam. Thus warming the atmosphere
without in the least maring its purity and naturalness.
This I accomplish in the following way.
1st. I make of copper, brass or tin, or any suitable metal any number of steam
pipes these pipes to have air tubes or not inserted in them. These steam pipes I
place parallel or perpendicular, or at angle, or any position these pipes are connected
with each other by two small tubes called inlet & outlet from which the steam may
redily pass from one to the other, underneath or in any convenient place, ether
attached or disconnected with the said steam pipes, I have two or more cisterns
under one of which I place gas jet, lamp, or any heat giving power to boil the
water and create steam. To this boiler, pipes run to the cold water cistern to give a
constant supply of water to the boiler for any given time.
The steam passes direct from the boiler into the two first tubes and hence from
one to the other untill it finally reaches the top where it is condenced and
carried by a simple tube into the cold water cistern bence back again into the
boiler.
I claim for this invention 1st. Absolute purity of the heated room, because no
portion of the air is in any way consumed nor does the steam ever mingle with the
atmosphere.
2nd. That with the smallest possible quantity of gas oil, fuel or heat creating
power, 1 form that marvelous heat giving power, steam, which I utilize untill. it is
condenced and returns again as water into the boiler again to be converted into
steam.
A candle, night light, small lamp or gas, that will keep half a pint of water boiling
The heat
is all that is necessary to keep the apparatus working it is inexhustable.
giving power being the steam and not the light by which the water is boiled, when
gas is used though only the smallest atmospheric burner a flue pipe is used that
may be carried into the open or a jet of steam carried into it thus destroying its
dryness and impurity and increasing the warmth of the chamber.
The apparatus
is under perfect control by means of a tap whereby the quantity of steam is
regulated.

COMPLETE SPECIFICATION.
Steam Apparatus for Heating Rooms or other Structures.
I JOHN ALFRED GROOM of 8 Seckford Street Clerkenwell E.C., do hereby declare
the nature of my said invention and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement:—
The object of my invention is to manufacture an improved apparatus for heating
rooms and other structures.
In carrying out my invention I make use of tubes formed of copper, brass, tin,

page_text: or any other suitable material. These pipes may be placed horizontally, vertically or
diagonally. Air tubes are (preferably) inserted in these main tubes; in order to
increase the heating surface and efficiency of the appliance.
When two or more of these pipes are used, they are connected together by inlet
and outlet pipes for the passage of steam from one to the other.
A small steam boiler, heated by gas or other fuel is used to supply steam to the
said main tube or tubes; and one or more cold water cistern or cisterns, is or are
used to receive the condensed water, and supply the boiler.
And in order that my said invention may be particularly described and ascertained
reference is hereby made to the accompanying Drawing, being an elevation partly
in section, illustrating one method of carrying out my invention.
a is a horizontal tube, closed at each end. b. b. b. b. are conical tubes of the
"Galloway" type, soldered to and made steam and air tight in the tube a. c. is an
upright boiler, enclosed in the case e and heated by an atmospheric gas burner d.
ff are two cold water cisterns. g is a funnel or flue leading the products of
combustion from the case e into the main tube a.
The apparatus is supported by standards n n or by other suitable means.
The action of the apparatus is as follows. Steam is generated in the boiler c.
The steam passes through the pipes h. h. into the main tube a.
The main tube is thereby heated, heat being also imparted to the conical tubes b. b.
This causes a current of air to pass upwards, in the direction of the arrows, through
the tubes b. b.
k. k. are return tubes, which carry the water arising from the condensation of the
steam, down to the cisterns f. f. m. m. are feed tubes which carry the condensed
water back to the boiler.
In some cases I make small holes in the pipes h. h. at i i, whereby a very small
quantity of steam is allowed to pass out and mix with the circulating, air so as to
moisten the same.
The waste gases from the casing e enter the main tube a by the flue g and are
carried from the tube a by the tube o which has an elbow at p leading to any convenient
flue. The pipe conveys the condensed liquid to the reservoir f, or the flue g may
(if preferred) be carried directly to the outside of the building so as to carry away
the gases without their entering the tube a.
It is obvious that my improved apparatus may be constructed in various ways and
with numerous modifications, the number of tubes, and the form and disposition of
the same, being arranged to suit the size and character of the structure to which it is
to be applied.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is.
1. The improved method of heating rooms and other structures, substantially as
herein before described and illustrated by the drawing.
2. The general construction, combination and arrangement of the several and
respective parts together forming my invention of steam apparatus for heating
rooms or other structures substantially as hereinbefore described and illustrated by
the Drawing.
