PROVISIONAL SPECIFICATION.
Raising and Lowering Gallery Holders of Paraffin or other Lamps
for the Purpose of Lighting same without Removing Globe or
Chimney.
HENRY ALFORD WALKER Bellevue Cottage Epping Essex Engineer do hereby
declare the nature of this invention to be as follows:-
My invention has for its object an improved movement to facilitate the raising of
globe &c. chimney galleries or holders of paraffin & other lamps to allow for the
trimming of wicks lighting & filling & consists of an improved method of raising &
lowering the said globe & chimney gallery in a perpendicular or oblique direction &
having full controll over the same, at any point & also of turning the said gallery
holder entirely from above the wick cases, thus allowing the same to be thoroughly
cleaned &c. In my invention the gallery holder is raised in a perpendicular or oblique
direction by the action of a screw, lever, cam, or rack, or other suitable movement
acting on two or more compound levers generaly known as agregate or lazy tongue
movement, which said compound lever shall work perpendicularly by the side of
the wick cases & be attached to the gallery holder by four points two of which may
work as pivots the other two be attached, by a catch or other suitable fastening the
release of which will allow the gallery holder, to turn on the said pivots & thus remove
entirely away from over the wick cases, for the purpose of cleaning filling &c.

I, HENRY ALFORD WALKER of Bellevue Cottage, Epping in the County of Essex,
Commercial Traveller, 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 :-
the
My invention has for its object the raising and lowering of lamp galleries, in order
to facilitate the trimming of the wicks, the lighting of the lamp, and if necessary,
refilling of the oil reservoir, through the burner body part, without removing or
disturbing the globe, chimney or other parts carried by, or upon the said gallery ; and
my said invention, consists essentially in employing a series of cross arms, or arms
jointed together at their ends, and at their middles, and commonly known as lazy-
tongs, and which said lazy tongs are disposed and connected between the underside of
the lamp gallery, and the bottom of the burner body.
This jointed and connected system of cross arms, constitutes an extending and con-
tracting device, which when opened out, or elongated, by the bringing together of the
cross bars, gives an upward movement to the gallery, to which the top end, or ends
are connected and jointed, while the reverse action, gives a lowering motion to the
gallery; and when the said gallery is in its normal or lowered position, with its
underside in juxta position, or resting upon the top or sides of the burner body, the
raising and lowering expedient is enclosed within the said body.
Thus the system of jointed bars, are preferably disposed on the two opposite sides of
the wick cases, and with the free ends at the upper part, respectively jointed to the
underside of the gallery, and with one of the joints of each system working within
longitudinal slots of brackets carried by the gallery, so as thereby to admit of the
opening out, or folding in of the bars, on the said gallery being elevated or lowered.
The lower free, and overlapping ends are jointed and connected to the bottom of
the burner body, as are the top ends, but with the ends, whose joints work within like
slots of brackets as aforesaid, connected together by a coupling bar, or cross piece, and
to the middle of this cross piece, the inner end of an operating screw or screw lever,
swivels, and with the worm part of the screw passing outwardly through a screw box or
screw hole in the burner body.
The outward end of the shank of the screw, is provided with a milled head or turn
for the rotation of the screw, by which means, the gallery is raised and lowered.
Instead of employing two systems of jointed and connected arms aforesaid, one only

page_text: may be used, and with the upper and lower parts jointed and connected respectively
to the underside of the gallery, and to the bottom of the burner body, either by fixed
brackets, or by lugs.
The lower part of the system of jointed bars, have free ends, which are brought
together, or opened out either by a screw, or its mechanical equivalent, or by standing
out pusher plates; and when the gallery is in its fully raised position, the ends of the
said extended parts, rest upon the bottom of the burner, and keep the said gallery
elevated and fixed in position when raised.
In this last named modification, the gallery is provided with depending rods, whose
lower ends freely slide telescopically or otherwise, within guide holes or sockets in the
fixed burner part of the lamp.
I will now proceed to describe with reference to the accompanying Drawing, the
manner in which the same is to be performed.
Figure 1 represents in side elevation, partly in vertical section, a portion of a lamp
for burning light or other volatile oils, and which said burner, or portion of lamp as
aforesaid, is provided with an improvement or improvements made according to my
said invention. The shade holder or gallery part is represented in its lowered or
normal position, or in a position which it assumes, when the lamp is in use. Figure 2
represents the same, with the shade holder or gallery, elevated from the burner body,
for either the trimming of the wick or wicks, or for the lighting of the lamp, while
figure 3 represents a horizontal section upon the dotted lines A B figure 1; and
figures 4, 5 and 6 represent parts of the gallery raising mechanism separately.
The same letters of reference indicate corresponding parts in the several figures of
the Drawing.
a is the body of the burner, and b is the movable gallery or shade holder, carrying
the burner part b². care the wick cases or tubes, and d is a system of jointed and
connected bars commonly known as "lazy tongs," and having free and extended
upper and lower ends d² d². The upper ends are respectively jointed to the underside
of the gallery, and with the joints d³ connected to the brackets 63, and with the joints d¹
sliding within guide slots of brackets 64. The lower ends are connected respectively
at ds to the burner body, and at do, to a cross or coupling bar e. The joint of this last
connection moves within a slot e². fis a triple threaded screw, and g is a screw hole
nut or screw box in the burner body, and through which the said screw works. The
inner end of the screw, swivels or turns within a hole in the middle of the coupling
bar e, while f³ is the outer end or turn part of the said screw, by which the screw is
rotated, for the raising and lowering of the gallery.
By rotating the head or turn f³ of the screw f, from left to right, the lower ends d²
of the jointed and connected bars d are pushed inwards, or into the position as repre-
sented in figure 2, which turns the bars upon their joint centres, and increases the
distance between the top and bottom parts, thereby raising the gallery vertically, and
keeping it in its raised or elevated position above the tops of the wicks or wick cases,
for trimming or for lighting purposes.
To lower the gallery, to its normal position as represented in figure 1, rotate the
head 3 in the reverse direction, when the jointed system of bars are collapsed, and
the gallery necessarily lowered, by the lower ends de being drawn outwardly by the
reverse movement of the screw within the screw box.
"
"
Although I have described and represented two systems of jointed and connected
bars, or lazy tongs," disposed on the two opposite sides of the wick cases, yet only
one lazy tong" may be used. In this case, the gallery has a depending rod or rods,
working within sockets, so as to form guides, for determining the vertical movement, on
the opening out or closing in of the arms.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is,-
First Raising and lower lamp galleries or shade holders, and the parts carried by
it or them, by means of a single or double system of jointed and connected bars known

page_text: as a "lazy tongus," by which means, the said gallery is vertically raised or lowered,
on the opening out or closing in of the said jointed and connected bars, substantially
as described, and for the purpose as set forth.
Secondly-Connecting and jointing the respective extended ends d², of a system of
jointed and connected bars d, (laży tongs) by joints d³ d', with the latter working
within the slot of a bracket of the upper part, while the lower part is jointed and
connected at do, do, and with the Jatter working within a slot e² as set forth.
"
<<
Thirdly-Operating a system of jointed and connected bars, known as lazy
tongs," by means of a screw or its mechanical equivalent, working within a screw box
in the burner body, and which said screw is either connected at its inner end, to a
cross coupling bar e, or directly to one or other, or both of the arms d² of the said
lazy tongues," substantially as set forth.
Fourthly-The combination of a "lazy tongues," for the raising and lowering of
lamp galleries, with guide rods and guide sockets, substantially as described.
