Improvements in and in the Construction of Oil Stoves used for
Heating and Cooking.
We, JOHN HARPER AND COMPANY, LIMITED, of Albion Works, Willenhall in
the County of Stafford, Iron Founders, and CHARLES RETALLACK, of the same
address, Manager to the said Company, do hereby declare the nature of this
invention to be as follows:-
In an oil stove used for heating and cooking, as usually constructed, the burner
(or each burner), which is made of sheet metal, is fixed in place upon the oil
reservoir by means of screws, which necessitates drilling and tapping holes in the
top of the reservoir; and, moreover, as each burner is entirely unsupported at any
point above its base which rests directly upon a reservoir, it is very liable to
become bent out of shape and thus cause the flame to be out of centre with the slot
through the top of the dome, whereby the combustion is rendered imperfect with
the result of causing the stove to smoke and smell.
Now, this invention bas for its object, firstly, to provide means for fixing a
burner in place according to which no screws are required for the purpose and
consequently no holes are required therefor in the top of the reservoir, and the
burner is most efficiently supported against any pressure tending to bend it out
of shape.
This object is accomplished, according to this invention, by casting with the
gallery which supports the chimney a bridle-piece having a slot or oblong opening
therethrough through which the upper portion of the burner passes and within
which it fits. One side of the bridle-piece bears upon the boxing of the burner
through which the spindle passes on which the toothed wheels used in raising and
lowering the wicks are fixed, and thus keeps the burner pressed tightly down upon
the top of the reservoir. The bottom of the burner is formed with a flanged
or enlarged base which fits within a flange or rim projecting from the face of the
top of the reservoir, as in the case of burners fixed in the ordinary manner.
bridle piece takes the place of the screws above described in fixing the burner
securely upon the reservoir, and gives most efficient support to it at a height
considerably above its base and thus keeps it central with the slot through the top
of the dome. For convenience in manufacture, the slot or opening through the
bridle-piece is made somewhat wider than the thickness of the burner, and narrow
vertical fillets are formed to project from one side such distance that the burner
will be a fairly good fit between them and the opposite side of the slot.
The
+
Oil stoves used for heating or cooking, as usually constructed, have the handles
formed separately from the galleries, and each handle is fixed in place by means
of a screw which passes through a hole formed in the handle and also through
a hole formed in a foot of the gallery, or in an outside foot of one of the galleries
if two or more galleries are used in a single stove.
୮
Now, this invention has for its object, secondly, to avoid the unnecessary
multiplication of parts, and the unnecessary formation of holes, occasioned by
constructing and fixing the handles in the ordinary manner above described.
This object is effected, according to this invention, by forming the handles
each in one casting with the gallery alongside of which it is required in use.
If a single gallery only is used for a stove, both the handles are cast therewith;
but if two or more galleries are used in a stove, a handle is cast with each
gallery, or with each outside gallery.

page_text: A convenient application of this part of the invention consists in forming each
handle on a foot of the gallery, and in such case each handle may be formed as a
pair of horns branching out on opposite sides of the foot and leaving a space
between them for the insertion of the screw by which the foot is fixed to the top
of the reservoir; or each handle may be of any convenient shape which admits of s
its being conveniently cast together with a gallery.

Improvements in and in the Construction of Oil Stoves used for
Heating and Cooking.
We, JOHN HARPER AND COMPANY LIMITED, of Albion Works, Willenhall in
the County of Stafford, Iron Founders, and CHARLES RETALLACK, of the same
address, Manager to the said Company, 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 :-
In an oil stove used for heating and cooking, as usually constructed, the burner
(or each burner), which is made of sheet metal, is fixed in place upon the oil
reservoir by means of screws, which necessitates drilling and tapping holes in the
top of the reservoir; and, moreover, as each burner is entirely unsupported at any
point above its base, which rests directly upon a reservoir, it is very liable to become
bent out of shape and thus cause the flame to be out of centre with the slot through the
top of the dome, whereby the combustion is rendered imperfect with the result of
causing the stove to smoke and smell.
Now, this invention has for its object, firstly, to provide means for fixing a
burner in place according to which no screws are required for the purpose and
consequently no boles are required therefor in the top of the reservoir, and the
burner is most efficiently supported against any pressure tending to bend it out
of shape.
This object is accomplished, according to this invention, by casting with the
gallery which supports the chimney a bridle-piece having a slot or oblong opening
therethrough through which the upper portion of the burner passes and within
which it fits. One side of the bridle-piece bears upon the boxing of the burner
through which the spindle passes on which the toothed wheels used in raising and
lowering the wick are fixed, and thus keeps the burner pressed tightly down upon
the top of the reservoir.
This part of the invention (as also the part presently to be described) is illus-
trated, by the drawings herewith, of which Figure 1 is a side elevation of the
upper portion of the reservoir of an oil stove and of a single gallery, burner, and
dome carried thereby; Figure 2 is a transverse section taken on line x x of
Figure 1 and Figure 3 is a plan of Figure 1, with the dome omitted.
b
The burner A is of the usual or any convenient construction, and is shewn as
fitted with the usual spindle a which carries the toothed wheels k by means of
which the wick is raised and lowered. The burner is formed with a foot b of the
usual character by means of which it rests upon the top of the reservoir B, but no
provision is required for screwing the foot down upon the reservoir. The edge of
the base may rest within a rim e projecting from the face of the reservoir (or fit
easily around a corresponding rim d, or rest within the bottom of the portion
enclosed by the rims c and d) as in the case of a burner fixed in the usual manner;
but such is not essential, as owing to the method of fixing the burner the base
cannot well move out of place even if it simply rests upon the reservoir. D is the
bridle-piece which is formed with the gallery C. The burner A. passes up through

page_text: the slot or oblong opening 1 formed through the bridle-piece. The side e of the
bridle-piece is formed to bear upon the boxing f through which the spindle_a
passes, and thus securely holds down the burner upon the top of the reservoir B.
The bridle-piece thus takes the place of the screws usually employed to fix the
burner to the reservoir, and gives most efficient support to it at a height consider-
ably above its base and thus keeps it central with the slot g through the top of
the dome E.
For convenience of manufacture, the slot through the bridle-piece D is made
somewhat wider than the thickness of the burner, and narrow fillets are formed
to project from the side of the bridle-piece such distance, as shewn, that the
burner will be a fairly good fit between them and the opposite side of the slot.
Oil stoves used for heating or cooking, as usually constructed, have the handles
formed separately from the galleries, and each handle is fixed in place by means of
a screw which passes through a hole formed in the handle and also through a hole
formed in a foot of the gallery, or in an outside foot of one of the galleries if two
or more galleries are used in a single stove.
Now, this invention has for its object, secondly, to avoid the unnecessary multiplica-
tion of parts, and the unnecessary formation of holes, occasioned by constructing
and fixing the handles in the ordinary manner above described.
This object is effected, according to this invention, by forming the handles each
in one casting with the gallery alongside of which it is required in use. If a single
gallery only is used for a stove, both the handles are cast therewith; but if two or
more galleries are used for a stove (that is, for a stove having two or more burners),
a handle is cast with each gallery, or with each outside gallery. A convenient
application of this part of the invention is illustrated by the drawings herewith.
Each handle is shewn as formed on a foot of the gallery; and in such case it
is convenient to form each handle as a pair of horns j branching out on opposite
side of the foot and leaving a space between them for the insertion of the screw m
by which the foot F is fixed to the top of the reservoir B. Each handle may,
however, be of any convenient shape which admits of its being conveniently cast
together with a gallery.
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 :-
1. In an oil stove used for heating or cooking, the use, in combination with a
gallery for supporting a chimney, of a bridle-piece for supporting a burner at a
distance above its base, substantially as described.
2. In an oil stove used for heating or cooking, the use, in combination with
a gallery for supporting a chimney, of a bridle-piece for supporting a burner at a
distance above its base and for holding down said burner securely upon the oil
reservoir, substantially as described.
3. In an oil stove used for heating or cooking, the use of a bridle-piece con-
structed substantially as described and shewn by the drawings herewith, for the
purpose or purposes set forth.
4. In an oil stove used for heating or cooking, forming the handles each in one
casting with the gallery alongside of which it is required in use, substantially as
described.
5. In an oil stove used for heating or cooking, forming the handles each in one
casting with the gallery alongside of which it is required in use, and as a pair of
horns branching out on opposite sides of the foot of such gallery, substantially as
described and shewn by the drawings herewith.
