Year: 1885

page_text: I, FRANCIS ROBERT BAKER of Buckingham Street, Birmingham, in the County of
Warwick Engineer do hereby declare the nature of said invention for "IMPROVE-
MENTS IN LAMPS FOR BURNING VOLATILE HYDRO-CARBON AND OTHER OILS" to be
as follows:-
My invention has reference to the burner and gallery parts of lamps for burning
volatile hydro-carbon and other fixed oils; and my said invention has for its object
to facilitate the trimming of the wick or wicks, and the lighting of the lamp, and
also the refilling of the oil reservoir.
By constructing and arranging lamps, or the parts of lamps as hereinafter
described, the gallery supporting and carrying the burner, chimney, globe, dome or
reflector, can be raised for trimming or relighting the wicks, and refilling the oil
reservoir, without the chimney, globe or other parts supported by the gallery being
removed, or without disturbing the burner or any part thereof.
I will describe my invention as applied to a lamp for burning petroleum hydro
carbon oil.
My invention consists in raising together the burner, and globe holder or
gallery preferably, by means of coiled springs encircling two or more guide rods,
which work in sockets or tubes fixed within the burner body; the unfastening of
the gallery from the burner body leaves the springs which are under tension, free
to raise the said gallery to the desired height-The gallery is lowered and fastened
by pressing it vertically downwards so as to compress the spring, and when
compressed the yielding catches snap into notches and so hold the combined gallery
and burner.
Fitted within the burner body are two guides or short lengths of tubing into
which depending rods attached to the combined burner and gallery slide freely-
The rods being of a length to allow the combined gallery and burner to be
sufficiently elevated to gain free access to the wicks or burner body-A coiled
spring or springs encircle the guide rods between the burner body and the under-
side of the movable or sliding gallery-These springs are of sufficient tension to
raise the gallery and parts carried by it or upon it to the necessary height for the
trimming or refilling of the lamp.

page_text: A yielding catch fastens the movable gallery part to the body by taking into
notches or their equivalents-The yielding catch is formed from the flat metal
spring situated within and following the inner circumference of the burner body,
with pusher ends protruding through the sides, the yielding flat spring is fixed at
or about its middle to the metal of the lamp.
When it is required to raise the gallery, it is only necessary to press inwards the
pusher or pushers on the side when the springs under tension recoil and raise the
gallery to the desired height, and keep it there by their extension.
The parts are again fixed by pressing vertically downwards the gallery which is
held in position by the yielding catches, the spring remaining in a state of tension
within the burner body.
Instead of employing a coiled spring for raising the gallery described, a flat or
involute spring may be used with like effect, the necessary throw or rising being
effected through the intervention of a lever; or the gallery may be raised by the
extension of a spring or springs instead of by compression as described.

I, FRANCIS ROBERT BAKER of Buckingham Street, Birmingham, in the County of
Warwick, Engineer do hereby declare the nature of said invention for "IMPROVE-
MENTS IN LAMPS FOR BURNING VOLATILE HYDRO-CARBON AND OTHER OILS" 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 the burner and gallery parts of lamps for burning
volatile hydro-carbon and fixed oils; and my said invention has for its object to
facilitate the trimming of the wick or wicks and the lighting of the lamp, and also
the refilling of the oil reservoir.
By constructing and arranging lamps, or the parts of lamps as hereinafter
described, the gallery supporting and carrying the burner, chimney globe, dome or
reflector, can be raised for trimming or relighting the wicks, and refilling the oil
reservoir, without the chimney, globe or other parts supported by the gallery being
removed, or without disturbing the burner or any part thereof.
I will describe my invention as applied to a Lamp for burning Petroleum hydro
carbon oil.
My invention consists in raising together the burner, and globe holder or gallery,
by means of coiled springs encircling two or more guide rods, which work in
sockets or tubes fixed within the burner body; the unfastening of the gallery from
the burner body, leaves the springs which are under tension, free to raise the said
gallery to the desired height. The gallery is lowered and fastened by pressing it
vertically downwards so as to compress the spring, and when compressed, the
yielding catches snap into notches, and so hold the combined gallery and burner.
Fitted within the burner body are two guides or short lengths of tubing into
which depending rods attached to the combined burner and gallery slide freely-
The rods being of a length to allow the combined gallery and burner, to be
sufficiently elevated to gain free access to the wicks or burner body-A coiled
spring or springs encircle the guide rods between the burner body and the under-
side of the moving or sliding gallery-These springs are of sufficient tension to
raise the gallery and parts carried by it or upon it to the necessary height for the
trimming or refilling of the lamp.
A yielding catch fastens the movable gallery part to the body by taking into
notches or their equivalents. The yielding catch is formed from the flat metal
spring situated within, and following the inner circumference of the burner body,
with pusher ends protruding through the sides, the yielding flat spring is fixed at
or about its middle to the metal of the lamp.
When it is required to raise the gallery, it is only necessary to press inwards the
pusher or pushers on the side when the springs under tension recoil and raise the
gallery to the desired height, and keep it there by their extension.
The parts are again fixed by pressing vertically downwards the gallery which
is held in position by the yielding catches, the spring remaining in a state of
tension within the burner body.

page_text: Instead of employing a coiled spring for raising the gallery described, a flat
spring may be used with like effect. The necessary throw or lifting of the spring
may if necessary be effected through the intervention of a lever; or the gallery
may be raised by the extension of a spring or springs instead of by compression as
described.
I will now proceed to describe with reference to the accompanying Drawings the
manner in which the same is to be performed.
Figure 1 represents in side elevation, and figure 2 in longitudinal vertical
section a lamp burner constructed according to my invention, the gallery of the
burner being shown in its normal or lowered position-Figure 3 represents in
elevation the burner figure 1, with the gallery and parts carried by it raised from
the burner body, for either the lighting of the lamp, the trimming of the wicks, or
for the refilling of the oil reservoir-The refilling is effected through an opening in
the body of the burner-Figure 4 represents a longitudinal vertical section of
figure 3, and figure 5 is an end view of figure 3, or with the burner turned round
at right angles. Figure 6 shows a plan of the burner body part, so as to better
exhibit the fastening or catch arrangements, for the fixing of the gallery in its
closed or lowered. position-Figure 7 shows the important features of my invention
upon a larger scale-Figure 8 is also a large view of the fastener.
The same letters of reference indicate corresponding parts in the several figures
of the Drawing.
a is the body of the lamp and b the shade holder or gallery having on its
underside depending rods c c encircled by coiled springs d d which are for the
purpose of raising the gallery as hereinafter described-The lower ends of these
springs rest upon shoulders e³, e³, formed by the junction of the guide tubes e es
with each other-The latter tube is internally of the diameter of the rod c while
the former which is attached to the burner body is a little larger than the diameter
of the coiled spring surrounding each rod-The upper abutinents of the springs are
upon the undersides of the brackets 62 62 connected with the gallery b-ff are
rubber buffers or cushion pads situated near the ends of the guide rods c c The
buffer pads are for the purpose of reducing concussion or shock on the liberation of
the springs for the raising of the gallery-g g are fixed catches hanging from the
underside of the gallery, and h h are yielding catch loops situated on opposite sides
of the burner body-These spring catch loops or holdfasts are operated by
pushers protruding through the sides of the burner as best seen in the plan
figure 6-The pushers ²² are attached at the free ends of the loops h, while the
other ends are rivetted or affixed to the metal of the burner-Thus the means of
raising the gallery or shade bolder consists of a spring d surrounding guide
rods cc carried by the gallery, and which rods pass and slide freely through tubes
or sockets e e passing through, and attached to the burner body-The throw or
tension of the springs are sufficient to raise the gallery 6 and parts carried by it or
upon it to the necessary height so as to expose the wicks for the trimming or
lighting of the lamp..
The yielding catch fasteners hold the gallery of the lamp down, when it is in its
normal or closed position, and when the spring is under tension by the pressing
down of the gallery.
When it is desired to raise the gallery figures 1 and 2, for the trimming or
lighting of the wicks, press inwards the pushers h² h², when the yielding loop his
pressed inwards from in front of the catches y g and the gallery thus liberated is
raised vertically by the expansion of the coiled springs d d which were under
tension when the gallery was closed; that is, the liberation of the catches allows
the tension of the spring thus stored up to recoil and raise and keep the gallery to
the desired height as represented in figures 3, 4 and 5.
The buffers on the ends of the guide rods destroy any concussion or impact that
might occur between the terminal ends of the rods and the end of the guide tubes
on the forcing or shooting upwards of the gallery, by the force of the raising

page_text: spring Instead of employing rubber cushion springs as buffers, the same result
may be attained by using coiled springs to prevent concussion.
The closing of the gallery to its normal position, as represented at figures 1 and 2
is effected by pressing vertically downwards the said gallery, which compression,
puts the spring under tension, and forces aside the yielding fastener loop on the
body of the burner, which latter by its elasticity returns to the back of the catch
and holds or locks the gallery to the body of the burner. The gallery raising
spring at the same time being held in a state of tension or compression is enclosed
within the larger tube, passing through the said burner body.
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
The raising of lamp galleries or globe and chimney carriers, by means of a spring
or springs, which raise vertically the said gallery and objects supported by it, on
the liberation of a catch or other fastener, which retains the gallery in its normal
position, while the spring or springs is or are under tension-Any concussion
occasioned on the springs recoil or distension, being counteracted by buffer pads,
carried by the conductor rods-The parts of the lamp burner being arranged,
combined and acting in the way and for the purpose substantially as described
and illustrated.
