COMPLETE SPECIFICATION,
Improvements relating to Gas, Oil, and like Heating Stoves.
I, HERBERT VILLIERS RIPPINGILLE, trading as Rippingille Brothers, of
Sampson Road North, in the City of Birmingham, Manufacturer, 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 improvements in, or connected with gas, oil, and like
heating stoves.
The object of my invention is to provide a more ready and convenient means of
access to the burner or wick than exists with the stoves of the usual construction at
present in general use.
In order that my invention, and the methods of carrying the same into effect may
be the more readily understood, I append hereunto oue sheet of explanatory draw-
ings to be bereinafter referred to-
Figure 1. is a front elevation, and Figure 2 a sectional end elevation of one
method of applying my invention to an oil and like stove, while Figures 3 and 4 are
alternate or modified methods of application.
The same reference letters in the different views indicate the same parts.
In carrying my invention into effect I provide an opening or aperture in the
outer casing of the stove or in the chimney, adjacent to the burner or wick, and
cover the aperture by suitably mounted or framed shutters constructed of a trans-
parent or semi-transparent material preferably mica. I attach the shutters in one
convenient manner by forming them in two parts such as A A' Figures 1 and 2,
each part having a stalk or projecting arm B B¹ pivoted on small pins b b' secured
to the casing. The two parts are connected together by means of a wire or other
link piece C the connections being made upon opposite sides of the pivot pins so
that the movement of the one half on its pivot sets up a like movement but in
a contrary direction to the other half shutter. I so shape or form the arms that
the shutters shall have an equal or nearly equal movement about their respective
pivots.
I attach a spiral or other spring D between the two half shutters for the purpose
of maintaining them at their normal or closed position, and a small knob or other
raised portion such as E to act as a handle.
Instead of employing a link piece C to cause the movement of one half shutter to
set up a like movement in a contrary direction in the other half, I sometimes dis-
pense with the link and move each arm independently against the resistance of the
spring D by means of a small knob such as E or a like projection at the upper end
of each arm.
I preferably form a guide or guard at the lower end of the
shutters, arranged to suit their circular path of motion, in order to keep them in
close contact with the stove casing.
In another convenient method of applying my invention, I employ a sliding
shutter or shutters such as A A' (Figure 3) to slide between suitable guides F F
at their upper and lower edges, or to be suspended from one upper guiding and sup-
porting piece upon which they may be moved as required. The shutters are.
opened and closed by causing them to slide between or upon their guides, or I
employ a lazy tongs or like system of levers such as illustrated at Figure 4, to
enable a small initial movement of the levers to produce the required entire move-
ment of the shutter which is then preferably formed in the one piece. I sometimes
dispense with the guides F F Figure 3 and support the shutters by suspending
them by arms or levers B B¹ (represented by dotted lines at Figure 3) from the
common pivot pin 6. The opening and closing of the shutters is then produced by

page_text: the movement of the arms about their common pivot. By such means I am enabled
to obtain ready access to the wick or burner, for lighting or trimming operations,
and to readily cover the aperture at the conclusion of such operations and thus
protect the flame and prevent the escape of smoke or fumes.
I do not limit the application of my invention to any particular stove, but adapt
it for employment with varying patterns of gas, oil, or like heating stoves, making
modifications in its details to suit varying requirements.
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. The construction of shutters from mica or other transparent or semi-transparent
material, suitably mounted and suspended from pivots, and fitted with a spring for
retaining them in their closed position substantially as and for the purposes herein-
before described and as illustrated in the accompanying drawings.
2. The combination of a lazy tongs or like system of leverage with a shutter, to
enable a small initial movement of the levers to produce the required entire move-
ment of the shutter, substantially as and for the purposes herein before described,
and as illustrated in the accompanying drawings.
