PROVISIONAL SPECIFICATION.
Improvements in Air-heating Apparatus.
I, MICHAEL MARY BROPHY, of the Firm of James Slater & Company, of
The Holborn Engineering Works, 251 High Holborn, in the County of London,
Engineers, do hereby declare the nature of this invention to be as follows:-
:-
This invention relates to apparatus for heating air for warming apartments by
means of hot water or steam and especially to what are known as radiators and it
comprises the improvements hereinafter described.
In carrying out my invention I form the apparatus of a series of vertical sections
bolted together through which the water or steam circulates, the adjacent surfaces
of the sections being corrugated so as to form openings for the passage of the air,
the openings being of such form as to be easily swept clean by a suitable brush.
The said surfaces are also grooved near the edges of the sections to form openings
into which a suitable cement can be inserted to form tight joints.
The apparatus is advantageously provided with a shelf clear of the top of the
sections but hinged so as to enable it to be turned up out of the way when cleaning
the air-passages.
I provide for the passage of fresh air through the radiator into the apartment
by forming it with an enclosed base having an opening for the admission of the
air, the said opening being governed by a regulating flap or door operated by a
suitable handle. The said base is also provided with a loose cover or door.
In order that the flow and return pipes shall be placed as close to the ends of
the apparatus as possible, I arrange the controlling valves in the said pipes
instead of in branches on the pipes, and I arrange the valves so that the flow of
the water or steam in the pipes shall not be impeded when the valves are shut
off. For this purpose I place the valve proper at the side of the valve casing
adjacent to the radiator and in connection with an opening therein, the said valve
being advantageously in the form of a disc of the "hit and miss" type kept to its
'seat by the pressure of a spring and adapted to be rotated by a suitable handle.

Improvements in Air-heating Apparatus.
1, MICHAEL MARY BROPHY, of the Firm of James Slater & Company,
The Holborn Engineering Works, 251, High Holborn, in the County of London
Engineers, 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 :—
This invention relates to apparatus for beating air for warming apartments by
means of hot water or steam and especially to what are known as radiators and it
comprises the improvements hereinafter described.
In carrying out my invention I form the apparatus of a series of vertical hollow
نيم

page_text: sections bolted together through which the water or steam circulates, the adjacent
walls or surfaces of the sections being corrugated so as to form openings for the
passage of the air, the openings, being of such, form as to. be easily swept clean
by a suitable brush. The said surfaces are also grooved near the edges of the
sections to form openings into which a suitable cement can be inserted to form
tight joints.
The apparatus is advantageously provided with a shelf clear of the top of the
sections but hinged so as to enable it to be turned up out of the way when cleaning
the air-passages.
I provide for the passage of fresh air through the radiator into the apartment
by forming it with an enclosed base having an opening for the admission of the air,
the said opening being governed by a regulating flap or door operated by a
suitable handle. The said base is also provided with a loose cover or door.
To enable my invention to be fully understood I will describe how it can be
carried into practice by reference to the accompanying drawing, in which :-
Figure 1 is a sectional front elevation of heating apparatus constructed according
to my invention:
с
Figures 2 and 3 are respectively sections on the lines 2-2 and 3-3, Figure 1.
a, a are the vertical hollow sections forming the apparatus, and b, bare the
bolts connecting the sections together, the latter being formed at their upper and
lower ends with hollow bosses c, c (communicating with the interior of the sections)
for the passage of the heating medium and for the reception of the said bolts,
nuts d, d being screwed outo the ends of the bolts to clamp the sections together.
e, e are suitable packing rings placed hetween the bosses to form tight joints
and fare ribs formed within the bosses to support the bolts centrally therein.
are pins passed through the bolts b, b and engaging between the ribs f, f so
as to prevent the bolts turning round when the nuts d, d are secured therein.. The
bosses c, c at the upper part of the end sections are closed by the nuts d, d and
washers d', d' while those at the lower part of the end sections are adapted to have
the flow and return pipes (not shewn) connected thereto, they being made sufficiently
large as at c to enclose the nuts d, d which bear against the ribs f, f, the heating
medium passing around the nuts and between the ribs.
h
9, 9 are the corrugations in the adjacent walls or surfaces of the sections a, u,
which corrugations form openings h, open at the top and bottom for the passage
of the air to be heated up through the apparatus, the said openings as shewn being
adapted to be easily cleaned by a suitable brush passed down through them. By
forming the said walls corrugated a comparatively large heating; surface is
obtained.
hare the grooves near.the edges of the sections a, a and adapted for the recep-
tion of a suitable cement to form air-tight joints and so prevent any escape of the
air passing through the apparatus.
is the shelf arranged at the top of the apparatus but clear of the sections,
and j,j are the hinges whereby it can be turned up out of the way to enable the
cleaning brush to be easily passed into the openings h, h
k is the enclosed base of the apparatus and is the opening therein for the
admission of the air. m.is the flap or door for regulating the flow of air through
the apparatus and n is the handle for adjusting the position of the said flap or
door, the said handle being connected with the Hap through the medium of: a rodo,
a lever p and a shaft g to which the flap m is attached. The rod o is advantageously
held in any position into which it may have been moved by a friction device which
consists of a casing r having holes through which the said rod passes and, a. loose
collar & encircling the rod, the said collar being caused to press the rod against one
side of the holes in the casing: by means of a spring t, the friction, thus set up
between the rod and the sides of the holes serving to hold it in position.
8
u is the loose door or cover provided at the front, of the base, the said, door
being supported in position by lugs. v, v at each side of the door opening, and by a
ledge w formed upon the sections a, a:

page_text: By this construction it will be seen that the heating medium being passed into the
apparatus through one of the openings c¹ will circulate through the apparatus, heat
the corrugated walls of the sections a, a and pass out of the other opening c', the
fresh air at the same time passing through the opening and up between the said
walls and being heated by contact therewith, the air then escaping from the top of
the apparatus into the apartment.
In order that the flow and return pipes shall be placed as close to the ends of
the apparatus as possible, I arrange the controlling valves in the said pipes instead
of in branches on the pipes, and I arrange the valves so that the flow of the
water or steam in the pipes shall not be impeded when the valves are shut off.
For this purpose I place the valve proper at the side of the valve casing adjacent
to the radiator and in connection with an opening therein, the said valve being
advantageously in the form of a disc of the "hit and miss" type kept to its seat
by the pressure of a spring and adapted to be rotated by a suitable handle.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. Air-heating apparatus comprising a series of hollow sections through which
the heating medium circulates and having the adjacent walls or surfaces corrugated,
substantially as, and for the purposes, described.
2. The manufacture and use of the improved air-heating apparatus hereinbefore
described and illustrated in the accompanying drawing.
