Complete Specification Left, 25th June, 1892-Accepted, 30th July, 1892
PROVISIONAL SPECIFICATION.
A Combined Damper or Draught Regulator and Case for Steam
Boiler and other Furnaces.
I, FREDERICK PACKER of 24, Kender Street, New Cross Road, in the County
of Surrey, Engine Smith, do hereby declare the nature of this invention to be as
follows:-
My invention relates to a damper or draught regulator and case, which has for
its object:
Simplicity of fixing, saving of fuel by its perfect action, and the impossibility of
becoming clogged in any way whatsoever by the accumulation of dust from the
furnace; the said object being attained as hereinafter described.
The case is a circular iron tube, entirely plain throughout the inside, with a hole
drilled through each side.
The damper plate is an elliptical plate of iron, recessed at each side so as to
fasten to a crank spindle for its perfect action; the said spindle being made in two
pieces so as to lap one over the other across the centre of damper plate, and fastened
to said damper plate by means of bolts. The extreme ends of spindle are inserted
in the holes in case, which are the bearings. The damper plate will then, by reason
of its shape, recline in an oblique direction.
It is obvious that the iron forming the different parts of my damper and case may
be wrought or cast, and that the said case may be composed of a square tube with
a rectangular damper plate as may be desired, without in any way departing from
the spirit of my invention.

COMPLETE SPECIFICATION.
A Combined Damper or Draught Regulator and Case for Steam
Boiler and other Furnaces.
I, FREDERICK PACKER,, of 24, Kender Street, New Cross Road, in the County
of Surrey, Engine Smith 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 relates to a damper or draught regulator and case which has for its
object:
Simplicity of fixing, saving of fuel by its perfect action, and the impossibility of
becoming clogged in any way whatsoever by the accumulation of dust from the
furnace. The said object being attained as hereinafter described.
The case is a circular iron tube, entirely plain throughout the inside, with a hole
drilled through each side.
The damper plate is an elliptical plate of iron, recessed at each side, so as to
fasten to a cranked spindle for its perfect action; the said spindle being made in
two pieces so as to lap one over the other across the centre of damper plate, and
fastened to said damper plate by means of bolts. The extreme ends of spindle are
inserted in the holes in case, which are the bearings.
The damper plate will then by reason of its shape, recline in an oblique direction.
It is obvious that the iron, forming the different parts of my damper and case,
may be wrought or cast, and that the said case may be composed of a square tube.
with a rectangular damper plate as may be desired, without in any way departing
from the spirit of my invention.

page_text: In order that my invention may be the better understood, I now proceed to
describe the same in relation to the accompanying drawings, reference being had to
the letters and figures marked thereon.
Fig. 1. represents the damper plate and case, embodying my invention.
Fig. 2. represents the damper plate-having a recess D. at each side-with crank
spindle attached.
-
Fig. 3. represents the spindle, being a crank spindle, made in two pieces, to be
fastened to damper plate by means of bolts as shewn in Fig. 2.
Referring to the drawing by letters :-
A. is the damper case; a circular tube of iron, having a hole drilled through
each side to receive the ends of spindle C.
B. is the damper plate or draught regulator, made elliptical in shape, so as to
recline in an oblique direction inside the case A.
C. is the spindle, made in two pieces so as to be easily connected to damper
plate B. by means of bolts as in manner shewn in drawing.
The said spindle by being made in two pieces is readily placed in its position
through damper case A.
'
E. E. represents the bearings for spindle C.
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 :-
1. A cast or wrought iron tube, circular or square, with a hc drilled through
each side; the said holes forming the bearings for spindle C, as aforesaid.
2. A plate of cast or wrought iron, elliptical or rectangular in shape, working in
iron tube, the said plate having a crank spindle fastened across the centre by means
of bolts, the ends of said spindle being inserted through the holes in the aforesaid
tube for the purpose described.
3. For the combination of the tube-circular or square as set forth-and plate,
elliptical or rectangular as set forth-and spindle, all to act as aforesaid and for the
purpose described.
Dated this 25th day of June 1892.
