COMPLETE SPECIFICATION.
A New Damper and Air Supply Regulating Arrangement for Heating
Apparatus.
I, FREDERICK WILLIAM GOLBY, of 36, Chancery Lane, in the County of Middle-
sex, Patent Agent, do hereby declare the nature of this invention and in what
manner the same is to be performed, as communicated to me by Sifride Demoulin,
of Farciennes, Belgium, Builder, to be particularly described and ascertained in
and by the following statement:—
This invention relates to a new damper and air supply regulating arrangement
for heating apparatus of all kinds.
The damper and air supply regulating arrangement consists as illustrated in
the accompanying drawings of three principal parts, viz., the air shaft L, the
valve M and the regulator N, these parts being preferably castings.
In the air-shaft L an opening O is formed, which is closed or opened according
as the valve M is lowered or raised.
In the drawings Fig. 1 is a front elevation and Fig. 2 a plan of the arrange-
ment, Fig. 3 is a section taken on the line AB in Fig. 1, with the valve placed
at "strong," as indicated by the letter c. In this position the opening 0 of the
air-shaft is closed and the draught comes direct from the stove or other heating
apparatus.

Figs. 4 and 6 are sections along the lines A EF and CDEF respectively in
Fig. 1 showing the damper arrangement with the valve arrested at moderate
as indicated by the letter b. In this position the opening 0 of the air-shaft is
open so that the air entering therethrough participates in the draught. The cold
air enters partly by this opening 0, whilst the draught in the air shaft is
diminished in consequence of the valve, which leaves no more than half of the
shaft L for the escape of the combustion gases.
"
Fig. 5 is a section along the lines A G H in Fig. 1 showing the damper arrange-
iment with the valve raised to " feeble as indicated by the letter a. There is no
longer in the shaft L any opening from the stove or other heating apparatus
except that which is necessary for the passage of the combustion gases, which are
attracted by the current of air created by the introduction of cold air through
the opening 0 (see the arrow d).

Operation. Fig. 1 shows the "feeble moderate" b, and "strong" c, posi-
tions. According as it may be desired that the stove should burn feebly, moderately
or strongly, the regulator is brought in front of one of the inscribed letters a, b or c.
Amongst the advantages presented by the present invention may be mentioned
the application of this damper arrangement to a heating apparatus such as is
shown in sectional elevation in Fig. 7.
This application allows on the one hand; regulating as desired to any degree
of heat, by means of the indications "feeble" a, "moderate"
b, and "strong" G.
a considerable economy of fuel being thus effected. On the other hand, any intro-
duction of the combustion gases into the room is rendered impossible, as these
are drawn off by the continuous current, the shaft being always open to the stove.

page_text: It may likewise be mentioned that all actual dampers, sliding bolts, sliding
bars &c. are dispensed with, as the valve performs the work of these.
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:
A new damper and air supply regulating arrangement for heating apparatus of
all kinds, distinguished by the special arrangement of an air-shaft L, a valve M
and a regulator N, these parts being combined in such a manner that they form
together a damper and air supply arrangement allowing of regulating as desired
to any degree of heat, substantially as herein described.
