page_text: I, FREDERICK RYLAND, of Houghton Street, West Bromwich, in the County
of Stafford, Ironfounder, do hereby declare the nature of this invention to be as
follows:-
My invention has reference to lamps burning light or volatile oils such as
petroleum and paraffin oils the parts of which lamps are arranged for heating in
contradistinction to lighting purposes. Lamps of the kind referred to are known
in commerce as lamp stoves.
In lamp stoves as ordinarily constructed the chimney surmounted by the stand
or support on which the vessel or articles to be heated rests, is connected to the
body of the lamp by means of a hinge joint. For the purpose of gaining access to
the wick for trimming and lighting as well as for filling the reservoir with oil the
chimney is turned aside on its hinge. My invention has for its object. to remedy
the inconveniences attending this method of construction and consists in constructing
and combining the parts of the lamp stoves in the manner hereinafter described.
In the body of the lamp I fix two vertical tubes. In these tubes are rods sliding
freely therein. These rods carry at their tops a strong ring supporting the chimney
of the lamp which chimney carries the stand or support on which the vessel or
article to be heated rests. To the body of the lamp the lower end of a flat vertical
arm is attached by a screw pin, on which the said arm is capable of turning. The
upper end of this arm passes through a loop or guide on the ring carrying the
chimney. The said arm has two notches on its edges one notch being near its
lower end and on one edge; the other notch being near the top of the said arm
and on its opposite edge.
The action of the parts is as follows:-When the parts are in their normal
positions, that is, in the positions they respectively occupy when the lamp is burning,
the chimney is in its lowest position and is locked in position by the lower notch on
the arm engaging with one side of the loop in the ring carrying the chimney.
When for the purpose of lighting or extinguishing the lamp, för trimming the wick
or filling the oil reservoir or for other purpose, it is desirable to raise the chimney
and to support it temporarily in its raised position the notched arm is turned aside
and the chimney unlocked. The chimney can then be raised vertically by its
supporting rods sliding in the tubes fixed in the body of the lamp. When in its
raised position the chimney can be temporarily supported there by so inclining the
notched arm as to make its upper notch engage with the side of the loop through
which it passes. In order to lower the chimney the notched arın is inclined so as
to liberate it from the loop when the chimney can descend, and when in its lowest
position it may be locked by so pressing the notched arm as to make its lower notch
engage with the loop through which it passes.

page_text: I, FREDERICK RYLAND, of Houghton Street, West Bromwich, in the County
of Stafford, Ironfounder, do hereby declare the nature of my 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 has reference to lamps burning light or volatile oils such as
petroleum and paraffin oils the parts of which lamps are arranged for heating in
contradistinction to lighting purposes. Lamps of the kind referred to are known
in commerce as lamp stoves.
In lamp stoves as ordinarily constructed the chimney surmounted by the stand
or support on which the vessel or article to be heated rests, is connected to the
body of the lamp by means of a hinge joint. For the purpose of gaining access to
the wick for trimming and lighting as well as for filling the reservoir with oil, the
chimney is turned aside on its hinge. My invention has for its object to remedy
the inconveniences attending this method of construction and consists in constructing
and combining the parts of the lamp stoves in the manner hereinafter described.
In the body of the lamp I fix two vertical tubes. In these tubes are rods sliding
freely therein. These rods carry at their tops a strong ring, supporting the
chimney of the lamp, which chimney carries the stand or support, on which the
vessel or article to be heated rests. To the budy of the lamp the lower end of a
flat vertical arm or lever is attached by a screw pin, on which the said arm or lever
is capable of turning. The upper end of this arm or lever passes through a loop or
guide on the ring carrying the chimney. The said arm or lever has two notches
on its edge, one notch being near its lower end, the other notch being near the top
of the said arm or lever.
The action of the parts is as follows;-When the parts are in their normal
positions, that is, in the positions they respectively occupy when the lamp is
burning, the chimney is in its lowest position and is locked in position by the lower
notch on the arm or lever engaging with one side of the loop in the ring carrying
the chimney. When for the purpose of lighting or extinguishing the lamp, for
trimming the wick, or filling the oil reservoir, or for other purposes, it is desirable
to raise the chimney and to support it temporarily in its raised position, the notched
arm or lever is turned aside and the chimney unlocked. The chimney can then be
raised vertically by its supporting rods sliding in the tubes fixed in the body of the
lamp. When in its raised position the chimney can be temporarily supported
thereby so moving the notched arm or lever as to make its upper notch engage
with the side of the loop through which it passes. In order to lower the chimney
the notched arm or lever is moved so as to liberate it from the loop when the
chimney can descend and when in its lowest position it may be locked by so
pressing the notched arm as to make its lower notch engage with the loop through
which it passes.
Figures 1 and 2 of the accompanying drawing represent respectively in side and
end elevation a lamp stove containing my improvements, the chimney of the stove
being in the position which it occupies when the stove is in use:
Figure 3 represents the said stove in side elevation with the chimney raised for
trimming or igniting the wick:
Figure 4 represents a portion of the stove in plan the stand surmounting the
chimney being removed.
The same letters of reference indicate the same parts in the several figures of
the drawing.
A is the oil reservoir or body of the stove and A' is the wick tube of the same;

page_text: B is the chimney of the said stove and B2 the stand fixed to and carried by the
said chimney on which stand a kettle or the like is supported.
In the top of the body A of the stove the vertical tubes a, a are fixed and to
the underside of the iron frame or ring 6 of the chimney B the depending rods b², b²
are screwed, the said rods 62, 62 being capable of a vertical sliding motion in the
tubes a, a.
To one side of the body A the nearly vertical lever or arm c is pivoted
the said lever passing through a slot or loop 61 in the frame of the chimney B.
In one edge of the lever care two notches marked respectively c², c³ the lower
one c² engaging with the edge of the slot 6' when the chimney is in its lowered
position thereby locking the said chimney in that position. The upper notch c³
engages with the edge of the slot 6' when the chimney is in its raised position as
represented in Figure 3 and thereby supports the said chimney in that position so
When the wick
as to facilitate the trimming or igniting of the wick of the stove.
has been ignited the lever c is turned into a vertical position when the chimney B
may be lowered into the position represented in Figures 1 and 2 and by turning
the lever in the direction proper for engaging the notch c² with the edge of
the slot b the chimney is locked in its lowered position.
Although I prefer to fix the rods 62, 62 to the underside of the frame or ring b
of the chimney and to arrange the tubes a, a in which the rods ², 62 slide in
the top of the body A of the stove yet this arrangement may be reversed;
that is to say, the rods may be fixed on the top of the body of the stove and
the tubes be carried by the ring or frame b of the movable chimney.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that I claim
as my invention of "Improvements in lamp stoves."
Providing the movable chimney of the stove with depending rods and the top
of the body or oil reservoir of the stove with tubes for the said depending rods
to slide in, the chimney being fixed in its raised or lowered position by a notched
arm or lever engaging with the edge of the frame of the chimney or by an
equivalent device substantially as hereinbefore described and illustrated in the
accompanying drawing; also the modification described in which the rods are
fixed on the top of the body and the tubes, which in this case slide on the rods,
to the movable chimney of the stove.
