Improvements in Gallery-raising Appliances for Lamps.
I PHILIP WINN of St. Thomas' Works, Granville Street, Birmingham in the County
of Warwick Brassfounder, do hereby declare the nature of this invention to be as
follows
My invention has for its object to simplify the apparatus employed for the purpose
of raising and lowering the chimney and globe gallery together of illuminating oil
or other lamps.
In carrying my invention into effect I construct the reservoir, body, burner, wick
tube or tubes, in any ordinary or well known manner, but I construct the sliding
gallery with two guiding stop rods which pass through the burner body and project
into the well or reservoir of the lamp. These stops I provide with collars or nuts
for the purpose of preventing the gallery being raised too far or from becoming
detached from the lamp.
I do not provide any levers or manipulating appliances for raising the gallery, but
prefer that this should be accomplished by the hand to lift the gallery direct and I
form within the burner, slots or grooves through which the guiding stops work,
and which allow of a vertical motion being made for a certain extent, and then
permit of a slight turning movement being given to the gallery, which allows it to
rest or stand upon the body of the burner, or upon a chamber formed within the slot
or grooves. Thus 1 form the grooves sometimes of a width suitable for the passage
of the end collars or stops of the guiding rods, and at the upper portion of these slots
or grooves I form a side channel or recess, so that the gallery on being turned
to one side will carry the end collars over on to the burner body, and thus permit
of the gallery being supported by the stops.
For convenience I sometimes form a side channel or side groove on each side
of the central groove so that when the gallery is turned in either direction the guide
stops enter the side chambers, & are safely held within.
By this my improved method of raising the gallery I ensure that the weight
shall be always sustained in a central manner, that is to say, the supporting pins
or stops are placed upon the central line of the gallery and are not turned or moved
out of that position.

COMPLETE SPECIFICATION.
Improvements in Gallery-raising Appliances for Lamps.
I, PHILIP WINN of St. Thomas' Works, Granville Street, Birmingham in the
County of Warwick, Brassfounder, 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 :-
My invention has for its object to simplify the apparatus employed for the purpose
of raising and lowering the chimney and globe gallery together of illuminating oil
or other lamps.
In carrying my invention into effect I construct the reservoir, body, burner,
wick tube or tubes in any ordinary or well known manner; but I construct the

page_text: sliding gallery with two guiding stop rods which pass through the burner body
and project into the well or reservoir of the lamp. These stops 1 provide with collars
or nuts for the purpose of preventing the gallery being raised too far, or from
becoming detached from the lamp. I do not provide any levers or manipulating
appliances for raising the gallery, but prefer that this should be accomplished by
the hand to lift the gallery direct and I form within the burner, slots or grooves
through which the guiding stops work, and which allow of a vertical motion being
made for a certain extent, and then permit of a slight turning movement being given
to the gallery, which allows it to rest or stand upon the body of the burner, or upon
a chamber formed within the slots or grooves. Thus I form the grooves sometimes
of a width suitable for the passage of the end collars or stops of the guiding rods,
and at the upper portion of these slots or grooves I form a side channel or recess,
so that the gallery on being turned to one side will carry the end collars over on
to the burner body and thus permit of the gallery being supported by the stops. For
convenience I sometimes form a side channel, or side groove on each side of the
central groove so that when the gallery is turned in either direction the guide stops
enter the side chambers, and are safely held within.
By this my improved method of raising the gallery ensure that the weight shall
be always sustained in a central manner, that is to say the supporting pins or stops
are placed upon the central line of the gallery and are not turned or moved out of that
position.
Referring to the accompanying sheet of drawings
Fig. 1 is a sectional elevation of part of a lamp showing one mode of applying my
invention;
Fig. 2 is a plan viewed from below.
Fig. 3 is a sectional elevation of a modified construction of my invention, and
Fig. 4 is also a plan viewed from below.
The lamp gallery A (Fig. 1) is carried by sliding slightly curved or flat bars B
working in slots shown at F, G, Fig. 2 and having at their lower ends E portions
cut out, so that when the lamp gallery A is raised to the upper position shown it can
be rotated and the portion H preferably undercut shall rest upon the portion of the
lamp C, the rod B being steadied by the washer or head D.
In this manner by raising the lamp gallery by hand and giving it a slight rotation
while in its upper position, the gallery, globe, and funnel are firmly held up so
that the lamp may be lighted or the wick trimmed. In the inverted plan (Fig. 2)
at G the washer or head D is shown in position, but at F it is supposed to be
removed to show the curved slot F in which one of the curved bars slides.
The wick tubes are shown at K, L.
If the curved bars B are sufficiently wide to form a considerable arc of the circle
they will have no tendency to fall over when the gallery is in its upper position,
even without the support of the head D, and this construction I sometimes adopt.
In Fig. 3 I show a modified arrangement in which I adopt round supporting
rods B and flatten the lower ends as seen at E Fig. 3 and in plan at Fig. 4. In
this case I form side slots M leading from the circular guiding aperture and when
A is raised to its upper position; the twisting of the gallery causes the flat parts E
to leave the round holes and enter the side slots which thus support it in its upper
position. Opposing slots to M may be arranged to cause the gallery to be sustained
if twisted or rotated slightly in either direction and the flat bars B may be notched
or cut as at E on both sides for the same purpose.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
Sustaining a lamp gallery in a raised position by means of an arrangement of
curved or flat bars or round rods with notches recesses or flats so that on sliding
up by hand and slightly rotating the gallery, the notches or projections engage and

page_text: uphold the gallery with its globe and other parts securely, substantially as herein-
before described and illustrated in the accompanying drawings.
