COMPLETE SPECIFICATION.
Improvements in and relating to Dampers, chiefly designed for
Kitchen or Cooking Ranges.
I, THOMAS WILLIAM ROGERS of 27 and 28, The Triangle, Bournemouth, in
the County of Hampshire, Ironmonger and Sanitary Engineer, 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 dampers and comprises various improvements hereinafter
described.
The main object of my said invention is to provide simple, cheap and effective
dampers for use in controlling the draught and directing the course of the heat of
the fire in kitchen or cooking ranges.
My improved dampers are so constructed and fitted to a range that a high
pressure boiler and an oven or ovens may be heated together or separately and by
preventing the escape of any part of the heat direct into the chimney, the heat
generated in the fire box can be more directly controlled and effectively utilized
than in ranges with dampers constructed and fitted in the ordinary way.
In order that my invention may be clearly understood I will refer to the
accompanying drawings in which :-
Fig. 1 shows respectively a side and end elevation of my improved dampers.
Fig. 2, is a modification of Fig. 1.
Fig. 3, is a front elevation-partly in section-of a range provided with my
dampers.
Fig. 4, is a sectional elevation on the line a. b. Fig. 3.
Like letters indicate corresponding parts throughout the drawings.
According to one form or modification of my invention-illustrated more
particularly at Fig. 1. C is a rod on which is formed or attached two pairs of lugs
or ear-pieces D, D¹, & D2, D3; arranged at about right angles to each other on the
said rod.
E, E', are two plates screwed or otherwise secured to the lugs D, D³, & D³, D³,
respectively and adapted to form the dampers E, E', when fitted to a range. F is
a handle fitted at one end of the rod C to operate said dampers.
According to another form or modification of my invention-illustrated at Fig. 2
of the drawings-C is a rod one half of which is passed through a hollow rod or
tube C, D, D³, & D2, D3, are two pairs of lugs or ear-pieces formed on or attached
to the tube C' and rod C respectively E, E are two plates suitably secured to the
said lugs and adapted to form dampers E, E', when fitted to a range F is a
handle fitted to one end of the tube C to operate damper E.
F, is a handle fitted to end portion of the rod C which projects through the
tube C to operate damper E.
In Figs. 3 & 4 of the drawings my dampers are shown (on a reduced scale) fitted
to a range having two ovens h,; f is the fire box and g the hot plate of the
range, i is a high pressure boiler, p is a passage under and around the boiler i. k is
a plate or partition extending right across the back of the fire box f between the
hot plate 9 and boiler i, r is a plate or partition fitted at the bottom of the flue s to
prevent the escape of heat direct into the chimney E, E', are the dampers fitted
between the hot plate g and boiler i one on each side of and at right angles to the
partition k. C is the rod to which the dampers are connected as hereinbefore
described. Each end of the said rod is supported in suitable bearings which may
be simply made by drilling a suitable hole through the front and back plates of the
range immediately above the level of the top of the ovens h, h. F is the handle

page_text: fitted at one end of the rod C which projects through the front plate of the range
to operate said dampers.
On moving the handle F from position 1 to 2 (Fig. 3), or vice versa, the rod C
turns and carries with it the dampers E, E', so that-according to one form of my
invention when one of the dampers is shut the other is open.
The dampers the position (1) shown-more especially at Figs. 3 & 4-would cause
the heat generated in the fire box f to pass through the passage p under and
around the boiler i and from thence over and around the ovens h, h; thus utilizing
the heat to a greater degree than heretofore by preventing the escape of the heat
direct into the chimney through central flues which is a distinctive feature of my
invention.
On moving the handle F to position 2 (Fig. 3) the dampers E¹ are closed and
dampers E are open; the heat is then applied directly to the ovens h, h'. When
it is required to open or close both dampers E, E' at the same time I provide the
modification hereinbefore described and illustrated at Fig. 2 of the drawings.
It is obvious my said invention may be advantageously applied otherwise than
to kitchen or cooking rauges.
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 :-
The improved dampers consisting of the parts constructed and arranged
substantially as hereinbefore described as and for the purposes specified.
Dated this 4th day of May 1894.
