Improved Apparatus for Heating and Ventilating.
I, JOHN CINNAMON, of 25, Central Avenue, New Brighton, in the County of
Richmond, and State of New York, United States of America, Commission
Merchant, do hereby declare the nature of this invention to be as follows:-
My invention has for its object to increase the heating force of a given amount
of wood or coal by producing combustion in such position that all the heat shall be
preserved, circumscribed, controlled, and directed in its path of radiation to take
effect only where it may be deemed desirable.
My invention is designed to economize fuel by preventing the escape of heat
during combustion into any wall or fireplace where it has generally been absorbed,
wasted, or lost, for any practical purposes of heating dwellings.
My invention is designed, further, to produce the combustion of wood or other
fuel in a grate at such an elevation above the level of the floor as to admit of the
rays of heat waves being radiated downwards to strike at any desired distance
across the room on the floor, and to be also reflected in like manner in waves of
forcible effect for heating a floor.
The invention contemplates the suspension of the grate in the air at a com-
paratively high elevation and apart from any wall and at a distance from any
surface whatever, except the direct supporting medium, but so that all the heat
that proceeds from the fire or from the hot bars or heated surface of the grate
must either strike the floor or strike a reflector situated in a position which will
send the reflected rays in the direction in which the said reflector turns, then
downward and forward.
A further object of this invention is to provide a heating medium constructed ou
the lines above set forth, which may be placed at any point desirable in a room or
other compartment of a dwelling, tent, hothouse, conservatory, or structure designed
for the comfort of birds or animals.
The reflector is of somewhat segmental shape being provided with a back and
being open at the front; and in the back portiou of the reflector an opening is
made which connects with an off-take pipe which is usually provided with a flue,
but the reflector may be of other shape if desired. The grate may be of any
desired form or construction and is supported preferably upon arms which are
connected with and are carried upwardly from a rod fitted to slide at its lower
end in a tubular support which may be a casing, or may be otherwise constructed,
and is generally located within a box adapted to receive ashes or coal that may
drop from the grate. The rod may be raised or lowered in any suitable manner;
as for example, the rod may be provided with a projecting pin travelling in a slide
made in the tubular support, the said pin having attached thereto a cable or chain
passed over suitable pulleys and provided at its lower end with a weight capable of
balancing the rod, the grate, and the material carried thereby, the rod being held
in any position to which it may be adjusted in its support by means of a set screw
or its equivalent; but ratchets or other hoisting mechanism may be employed to
control the movement of the rod.
A reflector is preferably secured to the supporting rod below the grate in order
that any heat that may radiate from the sides and bottom will be directed upward
to the main reflector.
One of the main features of the invention is to improve the draught and as

page_text: heretofore stated to improve the upward radiation of heat rays from the fire to the
reflector. This is accomplished by providing the grate with what I term a
radiating cover which consists preferably of a metal plate adapted to fit on the top
of the grate over the fuel, practically closing the said grate in an air-tight manner
at that point and protecting it from any upward draught except that the said
plate is provided with an opening at its back surrounded by a suitable collar
which collar is adapted to fit into a pipe whose inner end is received within the
off-take pipe and extending upward through the opening in the main reflector to a
suitable point within the same. An auxiliary pipe which is adapted as an off-take
for the grate is secured within the main off-take pipe, the lower end of said
auxiliary off-take pipe being brought to such position that when the grate is
elevated to a position within the reflector the off-take pipe will automatically
receive the collar of the radiating cover. The radiating cover rests mainly on the
grate by reason of its own weight, but it may be, and preferably is, held against
lateral movement by providing lugs on the bottom of the plate, adapted to fit in
the corners of a polygonal grate, or against the inner surface of the grate if of
circular or corresponding contour. The radiating cover is likewise preferably
made of sufficient size to extend an inch or more beyond the top edge of the grate,
and in order that the grate may be filled with coal without removing the radiating
cover the said cover is provided with a lid uormally closing an opening ordinarily
made at a central point therein. The surface of the plate has a radiator effect for
spreading the heat rays upwards by reflection.
The rod or stem may carry upward with it the ash receptacle, it then being
located between the lower reflector and the bottom of the grate.
The grate provided with the radiating cover may be suspended by means of a
cable or its equivalent passed from the grate over suitable guide pulleys secured
to the reflector and thence to a proper counterbalancing device or its equivalent;
or the main reflector may be supported from the tubular base in which the
grate supporting rod has movement so that the grate and its reflector are both
rendered portable and may be carried to any desired portion of a room or
building.

Improved Apparatus for Heating and Ventilating.
I JOHN CINNAMON, Commission Merchant, of 25 Central Avenue, New
Brighton, in the County of Richmond and State of New York, United States
of America 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 has for its object to increase the heating force of a given amount
of wood or coal by producing combustion in such position that all the beat shall be
preserved, circumscribed, controlled and directed in its path of radiation to take
effect only where it may be deemed desirable.
My invention is designed to economize fuel by preventing the escape of heat
during combustion into any wall or fire-place where it has generally been absorbed,
wasted or lost for any practical purposes of heating dwellings. My invention
is designed further to produce the combustion of wood or other fuel in a grate at
such an elevation above the level of the floor as to admit of the rays of heat waves
being radiated downward to strike at any desired distance across the room on the
floor, and to be also reflected in like manner in waves of forcible effect for heating

page_text: a floor. The invention contemplates the suspension of the grate in the air at a
comparatively high elevation and apart from any wall and at a distance from any
surface whatever except the direct supporting medium, so that all the heat that
proceeds from the fire or from the hot bars or heated surface of the grate must
either strike the floor or strike a reflector situated in a position which will send the
reflected rays in the direction in which the said reflector turns, then downward and
forward. A further object of this invention is to provide a heating medium con-
structed on the lines above set forth, which may be placed at any point desirable
in a room or other compartment of a dwelling tent, hothouse conservatory, or
structure designed for the comfort of birds or animals.
The invention consists in the novel construction and combination of the several
parts, as will be hereinafter fully set forth and pointed out in the claims.
Reference is to he had to the accompanying drawings forming a part of this
specification, in which similar characters of reference indicate corresponding parts
in all the figures.
Figure 1 is a partial vertical section and partial front elevation of the improved
heating device;
Figure 2 is a view taken similarly to Figure 1, but at right angles;
Figure 3 is a plan view of the bottom portion or base of the heating device, and
likewise a plan view of the grate ;
Figure 4 is a sectional view of a modified form of the heating device, and
Figure 5 is a partial side elevation and partial sectional view of a further
modified form of the device.
The reflector A is of somewhat segmental shape, heing provided with a back
and being open at the front; and in the back portion of the reflector an
opening B is made, which connects with an offtake pipe B', the latter being
usually provided with a flue B2, but the reflector may be of other shape if
desired.
The grate C may be of any desired form or construction, and is supported
preferably upon arms C, which are connected with and are carried upwardly
from a rod C, fitted to slide at its lower end in a tubular support C³, which
may be a casing or may be otherwise constructed, and is generally located within a
box C, adapted to receive ashes or coal that may drop from the grate.
The rod C may be raised or lowered in any suitable manner; as for example,
the rod may be provided with a pin D projecting from one of its sides and
travelling in a slide D' made in the tubular support C3, the said pin having
attached thereto a cable or chain D passed over suitable pulleys and provided at
its lower end with a weight D' capable of balancing the rod C, the grate and the
material carried thereby. The rod C2 is held in any position to which it may be
adjusted in its support by means of a set screw D or its equivalent; but if in
practice it is found desirable ratchets or other hoisting mechanism that will give
perfect control and a steady movement up and down without perceptible oscillation
may be employed to control the movement of the rod.
A reflector D' is preferably secured to the rod C below the grate, in order that
any heat that may radiate from the sides and bottom will be directed upward to
the maiu-reflector A. The practical simplicity of the stem or rod (³ is seen in
the elevating and lowering of piano lamps now in common use, but to my know-
ledge this principle has never until now been made practical in the manipulation
of any grates for heating rooms by reflected heat, so that the device would seem to
be unquestionably new for heating by high radiation and reflection.
One of the main features of the invention is to improve the draft, and as
beretofore stated to improve the upward radiation of heat rays from the fire to the
reflector. This is accomplished by providing the grate with what I term a
radiating cover E. This cover consists preferably of a metal plate adapted to fit
on the top of the grate over the fuel, practically closing the said grate in an air-
tight manner at that point and protecting it from any upward draft, except that the
said plate is provided with an opening E¹ at its back surrounded by a suitable

page_text: collar which collar is adapted to fit into a pipe F, whose inner end is received
within the offtake pipe B', and extends upward through the opening B in the main
reflector A to a suitable point within the same. The auxiliary pipe Es, which is
adapted as an offtake for the grate, is secured within the main offtake pipe B' in any
suitable or approved manner. The lower end of the auxiliary offtake pipe E is
brought to such position that when the grate is elevated to a position within the
reflector the offtake pipe will automatically receive the collar of the radiating
cover. The radiating cover rests mainly on the grate by reason of its own
weight, but it may be and preferably is held against lateral movement by providing
lugs on the bottom of the plate, adapted to fit in the corners of a polygonal
grate, or against the inner surface of the grate if of circular or corresponding
contour.
The radiating cover is likewise preferably made of sufficient size to extend an
inch or more beyond the top elge of the grate, and in order that the grate may be
filled with coal without removing the radiating cover, the said cover is provided
with a lid normally closing an opening ordinarily made at a central point therein.
The surface of the plate has a radiator effect for spreading the heat rays by
reflection.
Applicant has no knowledge of any basket grate being provided with any such
radiator, which radiator furnishes a steady beans of heat rays of equal temperature
pointed directly upward from all of its surface, directing the said heat rays to
the main reflector A.
The result obtained by the use of the radiating cover cannot be secured from
an open coal fire until it becomes entirely incandescent.
1 am aware that grates have heretofore been provided with hoods or blowers,
but the radiating cover cannot be classed with such devices.
The proper height of the rod or stem C will be determined by the area of the
floor to be heated. In a room twenty feet square the proper elevation of the
grate is from five to seven feet; in a zoological garden, where auimals require
good cold air with a warm floor and heat rays on their bodies, the grate may be
carried up much higher and will be located in the centre of the floor, which is also
the proper location in a tent, in both of which places, as also in hot-houses for
growing tropical plants or fruits, the reflecting cover of the basket grate may
have its smoke outlet in the centre, so that its collar may readily fit into a
centrally located conducting pipe leading into the interior of the tent or building.
When the grate is located in the centre of an apartment a circular reflector
would be provided for the grate instead of the semi-circular one shown in the
drawings.
If in practice it is found desirable the rod or stern C may carry upward with
it the ash receiving receptacle or pan, it then being located between the lower
reflector D and the bottom of the grate.
In Figure 4 I have illustrated the application of the radiating cover to a grate
which is suspended by means of a cable or its equivalent, passed from the grate
over suitable guide pulleys e secured to the reflector A and thence to a proper
counterbalancing device or its equivalent; and in Figure 5 I have illustrated the
main reflector A as supported from the tubular base C3 in which the grate
supporting rod has movement, so that under this latter construction the grate and
its reflector are both portable, and may be carried to any desired portion of a room
or any desired portion of a building.
Having now particularly described and ascertained the nature of may said inve
tion, and in what manner the same is to be performed, I declare that what I
claim is,-
1. A beating device, constructed substantially as herein shown and described.
