Improvements in Oil Stoves.
We, CHARLES RETALLACK, of Crawford Villa, Wellington Road Birchfield,
Handsworth in the County of Stafford. Ironfounder, and JOHN HARPER AND COMPANY
LIMITED of Albion Works, Willenhall in the said County, General Ironfounders and
Manufacturers, do hereby declare the nature of this invention to be as follows:-
This invention has for its object certain improvements in the construction of oil
stoves.
The oil reservoir is mounted upon rollers which run on rails within the bottom of
the case and upon corresponding rails on a flap door hereinafter described, so that it
may be readily run out of the case for filling, cleaning and such like operations, or for
use apart from the case, and also be readily run back into the case when required.
The gallery which supports the chimney or chimneys is hingel upon the reservoir so
that, when the reservoir is withdrawn from the case, such gallery may be readily turned
back to leave the burners exposed for cleaning. The usual perforated zinc or zincs or
corresponding part or parts through which the air passes to the wick or wicks is or are
permanently carried by the gallery and is or are turned back therewith. The chimney
or chimneys is or are loose from the gallery and when the stove is in use rest upon the
zinc or zincs or corresponding parts, and such chimney or chimneys is or are fitted
with V-shaped or other slides which fit within or around correspondingly-shaped
vertical guides carried by or cast together with the sides of the case. Suitable lever
mechanism, with proper connections, is arranged so that the chimney or chimneys may
he raised clear of the burners by means of a handle at the back of the stove, when it
is desired to remove the reservoir and burners from the case. A baffle-plate is carried
near the top of the case for directing the heated air and gases towards the front, back,
and sides, of the case, and up, chiefly, through perforations in the top which are
arranged near to the periphery thereof so as to give a better diffusion of heat in the
apartment in which the stove is used. This baffle-plate is conveniently pivotted with
its forward side overbalancing and resting upon a suitable stop; and by connecting
the rear portion thereof, by means of a wire or other connector, with a lever mounted
on the same axis as a lever which forms the handle aforesaid, and connecting the
forward portion thereof, by means of a similar connector, with the chimney or
chimneys, the plate acts as a portion of the mechanism by which the chimney or
chimneys is or are raised. The baffle-plate carries also a plate which answers the
purpose of a deflector and reflector. The top of the chimney or chimneys is fitted
with an extinguisher which is capable of being slid endways into position to cover and
close in the chimney opening or openings, and consists conveniently of a plate having
an opening or openings therethrough corresponding to the chimney opening or
openings and sliding between guides carried by the top plate of the chimney or
chimneys. This extinguisher is operated by means of a rod which passes through a
vertical slot in the side of the case. The lower portion of the front of the case is
formed as a flap door hinged at its lower edge and provided with rails on its inner face.
corresponding to those on the bottom of the case, and such flap is provided also with
knobs or projections which rest on the floor, when the flap is open, and maintain the
door in such position that the rails thereof are level with those of the case.
It is not,
of course, essential to use the rails, either in the case or on the flap. When they are
not used it is convenient to use wheels with elastic rims or tyres. When the flap is
open and the chimney or chimneys raised the reservoir and burners may be readily
drawn out on to the flap for filling or cleaning; and the remaining portion of the
front may be fixed in place by screws or nuts, so that it can readily be removed if
required and the chimney or chimneys withdrawn from the case, for the purpose of

page_text: using the interior portion of the stove, or stove proper, apart from the case, or for
other purpose.
In order to collect any oil which may drop on to or run down upon
the top of the reservoir, a continuous groove or channel is sunk into its upper side,
preferably just within the periphery thereof, and a hole is formed from the bottom of
such channel through the plate. This hole is stopped by a screw plug, except when
the oil collected in the channel is to be drawn off.
The above described invention, as it relates to the stove proper, may be advantageously
modified to some extent when the stove proper is not required to be used with a
'case. Under such circumstances the chimney or chimneys may be a fixture with the
gallery and be turned therewith as the gallery is turned on its hinge or hinges. In
other respects the parts of the stove proper may be substantially the same as described
for the modification in which the case is used.

Improvements in Oil Stoves.
We, CHARLES RETALLACK, of Crawford Villa, Wellington Road, Birchfield,
Handsworth in the County of Stafford, Ironfounder, and JOHN HARPER AND COMPANY,
LIMITED, of Albion Works, Willenhall in the said County, General Ironfounders and
Manufacturers, 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 has for its object certain improvements in the construction of oil
stoves.
In order that this invention may be clearly understood we will proceed to describe
it with reference to the accompanying drawings, which illustrate, in different views,
an oil stove constructed according to this invention.
Figure 1 is a sectional plan taken on line xx of Figure 2;
Figure 2 is a vertical section taken on line y y of Figure 1; and
Figure 3 is a vertical section taken on line 2 of Figure 2.
In Figures 1 and 2, however, the oil reservoir carrying the burners is shewn to be
within the case, as when in use, but this reservoir is shewn in Figure 3 to be run out
from the case for filling, cleaning, or such like operation, and the chimneys to be in
their raised position as hereinafter described.
The oil reservoir A is mounted upon rollers a which run on rails b (or within grooves
or along guides) within the bottom of the case B, and upon corresponding rails b' (or
within grooves or along guides) on a flap door C hereinafter described, so that it may
be readily run out of the case for filling, cleaning and such like operations, or for use
apart from the case, and also be readily run back into the case when required. The
gallery D which supports the chimneys (or chimney, if only one is used) is provided
with arms c by which it is hinged to the top of the reservoir, as shewn, and with legs d
by which it rests on the top of the reservoir. When the reservoir is drawn out from
the case the gallery may be turned back (as shewn by broken lines Figure 3) to leave
the burners e exposed for cleaning. The usual perforated zincs f, or corresponding
parts through which the air passes to the wicks, may be permanently fixed to the
gallery and be turned back there with as the gallery is raised for cleaning the burners;
or the zines may, of course, be loose if desired and be removed before turning up the
gallery. The chimneys E are loose from the gallery, and when the stove is in use rest
upon the zincs or corresponding parts f; and the chimneys are fitted with arms g
both at top and bottom, V-shaped or otherwise suitably shaped at their ends, to fit within
or around correspondingly shaped vertical guides gl carried by or cast together with the
sides of the case B. Suitable lever mechanism, with proper connections, is arranged so
that the chimneys may be raised clear of the burners, as shewn by Figure 3, by means of
a handle 1, hereinafter described, at the back of the stove, when it is desired to remove

page_text: the reservoir and burners from the case. A baffle plate F is carried near the top of the
case for directing the heated air and gases toward the front, back and sides of the case,
and up, chiefly, through perforations i in the top G which are arranged near to the
periphery thereof, as shewn, so as to give a better distribution of heat in the com
partment in which the stove is used. This baffle plate is pivoted by means of pivots j
resting within open-topped bearings i¹ cast with or fixed to the sides of the case, and
it is convenient to pivot it in such position that its forward side overbalances and rests
in its normal position upon a stop k projecting from the side of the case. A handle 1,
shewn by broken lines Figures 2 and 3 as it is behind other parts in Figure 2 and
would not appear in the section Figure 3, is carried on the end of a short spindle
which passes through the back of the case and on the inner end of which is mounted
a short arm m. The outer end of this arm m is connected, by means of a wire, chain,
or other connector n, with the back of the baffle plate F, and the chimneys are
suspended, by means of a bail or loop o and rod p, from the portion of the baffle
plate which is forward of its pivots, and thus by turning the handle in the right
direction the chimneys may be raised into the position shewn by Figure 3, the baffle
plate itself thus forming a portion of the mechanism by which the chimneys are raised.
The baffle plate F carries also a plate H which deflects the heat towards the front of
the stove; and when the front is formed with a transparent panel, as is usual with
stoves of this class, such plate H reflects also the light through such front, thus adding
to the cheerfulness of the stove's appearance. The surface of the plate H is preferably
made bright either by coating with tin, or by polishing, or in any convenient manner.
The top plate or frame J of the chimneys (or chimney) is fitted with an extinguisher
to cover and close in the chimney openings when it is desired to extinguish the flame,
and consists conveniently of a plate q, having openings q' therethrough corresponding
to the chimney openings, and sliding between guides r formed with or carried by the
top J. This extinguisher is operated by means of a rod s (shewn by broken lines
Figure 2 as it is, preferably, somewhat near the front of the case) which passes through
a vertical slot in the side of the case. It is not essential that the extinguisher be
formed to slide, though this is preferred, as it may be hinged so that it may be closed
down over the chimneys (or chimney). The lower portion of the front of the case is
formed as a flap door Chinged at its lower edge to the case and provided with rails &
(or grooves or guides) corresponding to the rails 6 (or grooves or guides) on the bottom
of the case, and such flap door is provided also with knobs or projections t which rest
on the floor when the flap is open, as shewn by Figure 3, and maintain the door in
such position that the rails (or grooves or guides) thereof are level with those of the
case. For convenience of removing this door it is hinged or jointed to the bottom of
the case simply by a pair of hooks w in the manner shewn more distinctly by enlarged
section, Figure 4. These hooks securely hold the lower edge of the door in position
when closed, and have sufficient hold also when the door is open to prevent it being
readily drawn forward accidentally. The upper edge of the door C may be held,
when closed, by turning catches (one of which c¹ is shewn by Figure 3) connected
with the knobs t which in such case are themselves capable of being turned to turn
the catches. It is not, of course, essential to use the rails (grooves or guides),
either in the case or on the flap door. When they are not used it is preferred to
use wheels with elastic rims or tyres for the oil reservoir. When the flap is open
and the chimneys raised, as shewn by Figure 3, the reservoir A and burners may
be readily drawn out on to the flap door for filling or cleaning or for other
purpose; and the remaining portion K of the front of the case may be hinged to
the case on one side and be held to the other side by means of screws or nuts, so
that on removal of the screws or nuts it can readily be opened back, if required,
and the chimneys withdrawn from the case, for the purpose of using the interior
portion of the stove or stove proper (that is to say the lamp which consists primarily
of the reservoir A, burners e, or burner if only one is required, and chimneys E,
or chimney if only one is required) apart from the case, or for other purpose.
break al is formed in each vertical guide g¹ to allow of the removal of the arms g
therefrom as the chimneys are removed. To remove the chimneys the rod p is,
A

page_text: of course, unhooked from the bail o, and the rod s disconnected from the extinguisher,
and to render the latter operation convenient the rod may be fastened by means. of
a vertical screw through a hole formed through its inner end. In order to collect
any oil which may drop on to or run down upon the top of the reservoir, a con-
tinuous groove or channel u is sunk into its upper side, preferably just within the
periphery thereof, as shewn, and a hole v'is formed from the bottom of such channel
through the plate. This hole is stopped by a screw plug which is removed when
the oil collected in the channel is to be drawn off.
The above described invention, as it relates to the stove proper, may be advan-
tageously modified to some extent when the stove is not required to be used with
a case. Under such circumstances the chimneys (or chimney) may be a fixture
with the gallery and be turned therewith as the gallery is turned on its hinges.
In other respects the parts of the stove proper may be substantially the same as
described for the modification in which the case is used.
Having now particularly described and ascertained. the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In an oil stove, the door fitted to answer both as a flap to the case and
as a platform on which to run out the reservoir A, substantially as described.
2. In an oil stove, the combination of an oil reservoir mounted upon rollers, with
rails (grooves or guides) in the bottom of the case and on a flap door hinged to
the case and capable of being opened down so as to bring its rails (grooves or
guides) level with those of the case, substantially as described and shewn, for the
purpose set forth.
.
3. In an oil stove, a gallery for supporting the chimney or chimneys hinged to
the oil reservoir, substantially as described and shewn, for the purpose set forth.
4. In an oil stove, the chimney or chimneys fitted to be capable of being raised
within the case clear above the burners by suitable mechanism, when it is desired
to remove the oil reservoir and burners from the case, substantially as described
and shewn.
5. The baffle-plate F pivotted to return by its own gravity into its horizontal
or normal position after being moved therefrom, and to remain in such position
until removed therefrom by mechanism provided for such purpose, substantially as
described and shewn, for the purpose set forth.
'
6. The combination of the baffle-plate F with the deflector plate H, substantially as
described and shewn, for the purpose set forth.
7. In an oil stove, an extinguisher fitted to the top of the chimneys (or chimney)
substantially as described, for the purpose set forth.
8. In an oil stove, an extinguisher formed to slide upon the top plate or frame of the
chimney or chimneys, substantially as described and shewn.
9. The groove or channel u around the upper portion of the oil reservoir, having a
suitable opening through the bottom thereof capable of being closed and opened at
will, substantially as described and shewn, for the purpose set forth.
