Improvements in Lamps or Burners for Lighting or Heating
Purposes.
We, JOHN CHARLES CRAMPIN READ of 8 Lordswood Road, Harborne in the
County of Stafford Engineer and CHARLES FITZROY ALEXANDER HALLIFAX
BAGOT of 59 Cadogan Square in the County of London Esquire do hereby
declare the nature of this invention to be as follows:-
This invention relates to the mechanism by which parts of the lamp or burner
are raised to allow of access to the wick for lighting or other purpose and has for
its object to provide a more efficient, simple and economical arrangement for the
purpose than those hitherto in use.
According to this invention the gallery which carries the glass or chimney and
also the globe, if a globe be used, is provided with depending arms or ribs which
are situated outside the metal perforated mounting which is screwed or otherwise
secured to the mount at the top of the reservoir. These arms or ribs are pre-
ferably connected to a ring which can slide up and down on the said perforated
mounting. At the upper part of this perforated mounting there is secured a
ring, or annular plate provided with a handle or other means for giving it
movement of partial rotation and from the underside of this ring or annular
plate depend inclines upon which rest pins or runners projecting from the arms
or ribs which depend from the gallery as aforesaid. At the top of the inclines
are rests or recesses for the reception of the pins or runners when they are at
the top of the inclines and at the lower ends of the inclines are also rests for
the pins or runners when they are at the bottom of the incline sthere being pro-
jections extending over the pins or runners when they are in the last named
positions so that the gallery cannot be lifted without partly rotating the ring or
annular plate aforesaid. When the said ring or annular plate is partly rotated
in one direction the inclines by acting on the pins or runners cause them and
the arms or ribs and gallery and the parts carried thereby to be raised they
being supported in this position by the pins or runners entering the rests or
recesses at the top of the inclines. The gallery and parts carried thereby are
lowered by partly rotating the ring or annular plate in the other direction when
the rests or recesses leave the pins or runners and they run down the inclines
and the gallery and parts carried thereby are lowered the pins or runners being
received at the lower parts of the inclines beneath the aforesaid projections which
prevent the gallery from being raised except by partly rotating the ring or annular
plate as aforesaid.
In order that the proper passage of air to the burner be not interfered with by
the arms or ribs and inclines aforesaid it is preferred to perforate them to allow of
the passage of air through them.

Improvements in Lamps or Burners for Lighting or Heating
Purposes.
We JOHN CHARLES CRAMPIN READ of 8 Lordswood Road, Harborne in the
County of Stafford, Engineer, and CHARLES FITZROY ALEXANDER HALLIFAX
BAGOT of 59 Cadogan Square in the County of London, Esquire, 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 the mechanism by which parts of the lamp or burner
are raised to allow of access to the wick for lighting or other purpose and has for
its object to provide a more efficient, simple, and convenient arrangement for the
purpose than those hitherto in use.
According to this invention the gallery which carries the glass or chimney, and
also the globe, if a globe be used, is provided with depending arms or ribs which
are situated outside a metal perforated mounting which is screwed or otherwise
secured to the mount at the top of the reservoir. These arms or ribs are preferably
connected to a ring which can slide up and down on the said perforated mounting.
At the upper part of this perforated mounting there is secured a ring, or annular
plate provided with a handle or other means for giving it movement of partial
rotation and from the underside of this ring or annular plate depend inclines upon
which rest pins or runners projecting from the arms or ribs which depend from the
gallery as aforesaid. At the top of the inclines are rests or recesses for the
reception of the pins or runners when they are at the top of the inclines and at
the lower ends of the inclines are also rests for the pins or runners when they are
at the bottom of the inclines there being projections extending over the pins or
runners when they are in the last named positions so that the gallery cannot be
lifted without partly rotating the ring or aunular plate aforesaid.
When the said
ring or annular plate is partly rotated in one direction the inclines by acting on
the pins or runners cause them and the arms or ribs and gallery and the parts
carried thereby to be raised, they being supported in this position by the pins or
runners entering the rests or recesses at the top of the inclines. The gallery and
parts carried thereby are lowered by partly rotating the ring or annular plate in
the other direction when the rests or recesses leave the pins or runners and they
run down the inclines and the gallery and parts carried thereby are lowered the
pins or runners being received at the lower parts of the inclines beneath the
aforesaid projections which prevent the gallery from being raised except by partly
rotating the ring or annular plate as aforesaid.
Figure 1 of the accompanying drawings represents in vertical section an oil
lamp, provided with our improvements.
Figure 2 is a sectional elevation of the lamp, the parts being shewn in the
position they occupy when the lamp is burning and Figure 3 is a similar view
shewing the parts in the position they occupy when the light is extinguished and
the gallery which carries the glass or chimney is raised to admit of access to the
wick for lighting.

3* is an opening by which to charge the reservoir with oil. 5 are wick tubes
containing ordinary cotton wicks and screw into a plate 6 which covers the opening
in the reservoir into which the burner is screwed. 4* is au incombustible top for
the wicks it being contained in an annular space 7 formed between two rings 8, 9
inserted in the top of the burner and retained therein by a ring 10 screwed onto
the top of the burner.

air chamber below the bottom of the chimney through which all air to support
combustion must pass to the burner. This chamber is formed by a plate 17
(carried on the device by which the gallery carrying the chimney is raised and
lowered) and a cup 18 carried by a ring 19 which screws onto the lower end of the
burner and provided with knobs or handles 20 by which it can be turned and so
raised and lowered to regulate or close the space between the upper edge thereof
and the plate 17 to regulate the admission of or cut off the supply of air to the
burner.
These
The lifter for raising the gallery (and parts which it carries) for lighting or
other purpose is arranged as follows. The gallery 11 which carries the glass or
chimney 12 and also the globe (if a globe be used) is provided with depending
arms or ribs 22 which are situated outside the metal perforated tube 15.
arms or ribs are preferably connected to a ring 22* which can slide up and down
on the said perforated tube. At the upper part of this perforated tube is the ring,
or annular grooved plate 23 in which the upper flange of the part or plate 17
turns it being provided with a handle 24 or other means for giving it movement of
partial rotation. To the part 17 is secured the ring 17* and from the underside of
this ring depend inclines 25 upon which rest pins or runners 27 projecting from the
arms or ribs 22 which depend from the gallery and pass through the ring 23. At
the top of the inclines are rests or recesses 26 for the reception of the pins or
runners 27 when they are at the top of the inclines and at the lower ends of the
inclines are also rests 28 for the pins or runners when they are at the bottom of
the inclines there being projections 29 extending over the pins or runners when
they are in the last named positions so that the gallery cannot be lifted without
partly rotating the ring or annular part or plate 17 aforesaid. When the said ring
or annular plate is partly rotated in one direction the inclines 25 by acting on the
pins or runners 27 cause them and the arms or ribs 22 and gallery and the parts
carried thereby to be raised into the position shown in Figure 3 they being
supported in this position by the pins or runners entering the rests or recesses 26
at the top of the inclines. The gallery and parts carried thereby are lowered by
partly rotating the ring or annular plate 17 in the other direction when the rests
or recesses 26 leave the pins or runners 27 and they run down the inclines 25 and
the gallery and parts carried thereby are lowered, the pins or runners being
received at the lower parts of the inclines beneath the aforesaid projections 29
which prevent the gallery from being raised except by partly rotating the ring or
annular plate as aforesaid.
In order that the proper passage of air to the burner be not interfered with by
the arms or ribs and inclines aforesaid they may be perforated to allow of the
passage of air through them.
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 18:-
1. In an oil lamp, a lifter for raising the gallery and the glass or chimney
carried thereby the said lifter consisting of a frame having inclined or helically
arranged surfaces connected at their upper and lower ends to rings and acting on
studs or runners projecting from arms or ribs depending from the gallery so that
when the frame is rotated in one direction the inclined or helically arranged
surfaces cause the gallery to rise; rests for the studs or runners being provided at
the upper ends of the inclines to retain the gallery in its elevated position and
projections at the lower ends of the inclines beneath which projections the studs or
runners engage when the gallery is in its lowest position and prevent the gallery

page_text: from being raised except by partially rotating the frame substantially as herein-
before described.
2. The combination with the subject matter of the preceding claiming clause of
a perforated tube or mounting surrounding the wick tube or wick tubes through
the perforations of which mounting air passes to the wick or wicks to support
combustion and on which mounting the rotatory portion of the lifter is fitted to
turn substantially as hereinbefore described.
