Improvements in or connected with Oil Stoves.
We, ALFRED HENRY GRIFFITHS, of Surrey Works, Smethwick, Managing
Director, and THOMAS BAKER SMITH, of 55 Douglas Road, Handsworth,
Manager of Lamp Department, both near the City of Birmingham, 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 oil stoves, and
refers more particularly to the flues of such stoves, and its object is to so construct
and arrange the said flues, that they may be readily moved to an exterior position
without entire removal, so that they may be easily freed from soot or other dirt or
grease, and which further facilitates the similar cleaning of the interior of the
stove, or such flues themselves when worn out or damaged, may be readily replaced
by others.
In order to make our invention clear, we have appended hereunto an illustrative
sheet of drawings, upon which are figures and numbers of reference, similar
numbers referring to the same thing or part, and in which :-
Fig. 1, shows a front view of a stove, such as this our invention may be applied
to, showing particularly the flues in position.
Fig. 2, is a plan view of the stove on line A-B (Fig. 1).
Fig. 3, is a similar view to that of Fig. 2, but further showing one of the flues
swung round to a position exterior to the body of the stove.
Fig. 4, is a sectional view in elevation of the flue.
Figs. 5, 6, & 7, are similar views showing a modification of this our invention, in
which the said flues are made to slide forward instead of being swung forward.
10, is the body of the stove; 11, 11, are the lamps; 12, is the bottom, and 13,
the top of the oven, which are rigidly fixed to the body 10. 14, 14, are the flues,
whose interiors coincide with the openings 15, made in the top and bottom
plates 12, and 13, and up which the heat and fumes &c. of the lamps pass.
If the lamps are well attended, they burn clean, and there is scarce any
accumulation of soot or dirt in these said flues, but with neglect (which is
frequently experienced), the soot and dirt soon accumulates within the flues, and
impedes the passing thereto, of heat into the oven.
To obviate this, and yet to so obtain access to the interior of the flues, without
their entire removal, we provide that the said flues shall be hinged or jointed at 16,
to the top plate 12, and the bottom plate 13, so that at will they may be swung
around as shown in Fig. 3, in the course indicated by dotted lines 17, 17ª.
To facilitate this we may make a cast iron top and bottom piece 18, 18, (see
Fig. 4), having the upward flange 19, upon which the tubular body of the flue may
be tightly placed or it may be rivetted thereto.
Again in Figs. 5 to 8, inclusive, we provide that the flues 14, shall be carried in
sliding guides 20, 20", which said guides are secured to the bottom plate 12, and
the top plate 13. In this case however, we further provide upon the rear end of
the flues, at the top and the bottom, the piece 21, having the outstanding
projections 22, 22.
After the flues are first slid into their places, we then turn up the end portion 23,
of the guides, as shown, so that when the flue is now drawn outwards, it cannot be
separated from the stove, but is always retained in a position that readily admits

page_text: of being easily pushed back into position. Thus each flue is quite independent of
the other, and may be internally cleaned without interference with the oven.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
Making and arranging the fines of oil stoves, so that they may independently of
each other, be brought to the exterior of the oven, constructed and operating as
set forth and shown upon the drawings.
