"IMPROVEMENTS IN LAMPS FOR BURNING LIGHT OR VOLATILE OILS"
My invention has for its object to facilitate the trimming of the wicks and the
lighting of the said lamps and the filling of the reservoirs of the said lamps; and
my said invention consists of the construction and arrangement hereinafter
described of the parts of the said lainps, whereby the gallery carrying the chimney
and globe and dome or deflector of the lamp can be raised for trimming the wicks
and for lighting the lamp without the removal of the chimney and globe from the
gallery, and the burner raised so as to expose the open mouth of the reservoir for
filling the same with oil without separating or detaching any of the parts of the
lamp.
To the underside of the metallic mount or collar cemented to the mouth of the
oil reservoir. I fix vertically two metallic tubes of small diameter the lower ends of
the said tubes being connected by a horizontal ring for the purpose of giving them
stability. On the underside of the gallery carrying the chimney and globe are two
metallic rods of a diameter suitable for sliding steadily in the said tubes. On one
side of the metallic mount or collar described, is a spring bolt through which
one of the said rods passes the said rod having a notch into which the said
spring bolt snaps when the gallery has been raised to the required height and
fixes the gallery in its mised position. By pressing upon the outer end of the
spring bolt it can be disengaged from the notch in the rod and the gallery
can then be lowered
The burner of the lamp is not fixed to the reservoir as is usual but is capable of
rising and falling. This is effected by making the rods by which the gallery is

page_text: carried pass through vertical tubes in the burner so that the burner can rise and
fall by sliding on the said rods. The burner, when raised can be fixed to the
gallery by a spring bolt or other fastening and the said burner may be fixed in its
lowest position by a ring turning on its lower end carrying bolts which engage
with studs on the mount or collar or by other fastening.
The fastenings described permit the gallery to be raised and supported in its
raised position; the burner to be raised and fixed in its raised position, the burner
to be fixed in its lowest position and the gallery also to be fixed in its lowest
position.
When the parts of the lamp are in their normal positions respectively, the burner
and gallery are fixed to the reservoir of the lamp. When for the purpose of
trimming the wicks or lighting the lamp it is necessary to give access to the wicks
the gallery is unbolted from the burner and raised. It is supported in its raised
position by the spring bolt described. After the trimming of the wicks or the
lighting of the lamp has been effected, the spring bolt is pressed upon when the
gallery can descend and may be bolted in its lowest position. When it is wished
to replenish the reservoir with oil the gallery is first raised. The buruer is unbolted
and raised and fixed in its raised position to the gallery. Or the gallery and burner
are raised together.
The open mouth of the reservoir is now fully exposed and oil can be readily
poured in to the required height, the surface of the oil being visible. When the
reservoir has been filled, the burner and gallery are lowered and fastened down.
It will thus be understood, that in lamps made according to my invention, the
wicks can be trimmed the lamp lighted and the oil reservoir filled without the
detachment of any of the parts of the lamp.
The gallery and buruer can however be readily removed from the reservoir for
the purpose of cleaning or repair, for the introduction of new wicks or for other
purposes.

JOSEPH HINKS, of Birmingham in the County of Warwick, Manufacturer
"IMPROVEMENTS IN LAMPS FOR BURNING LIGHT OR VOLATILE OILS »
My Invention has for its object to facilitate the trimming of the wicks and the
lighting of the said lamps and the filling of the reservoirs of the said lamps; and
my said invention consists of the construction and arrangements herein after
described of the parts of the said lamps, whereby the gallery carrying the chimney
and globe and dome or deflector of the lamp can be raised for trimming the wicks
and for lighting the lamp without the removal of the chimney and globe from the
gallery; and the burner raised so as to expose the open mouth of the reservoir for
filling the same with oil without separating or detaching any of the parts of the
lamp.
To the underside of the metallic mount or collar cemented to the mouth of the
oil reservoir, I fix vertically two metallic tubes of small diameter, the lower ends
of the said tubes being connected by a horizontal ring for the purpose of giving
them stability. On the underside of the gallery carrying the chimney and globe
are two metallic rods of a diameter suitable for sliding steadily in the said tubes.
On one side of the metallic mount or collar described is a spring bolt through which
one of the said rods passes, the said rod having a notch into which the said spring
bolt snaps when the gallery has been raised to the required height, and fixes the
gallery in its raised position. By pressing upon the outer end of the spring bolt,
it can be disengaged from the notch in the rod and the gallery can be lowered.
The burner of the lamp is not fixed to the reservoir as is usual but is capable of
rising and falling. This is effected by making the rods by which the gallery is
carried, pass through vertical tubes in the burner so that the burner can rise and
fall by sliding on the said rods. The burner when raised can be fixed to the gallery
by a spring bolt or other fastening and the said burner may be fixed in its lowest
position by a ring turning on its lower end carrying bolts which engage with studs
on the mount or collar or by other fastenings. The fastenings described permit
the gallery to be raised and supported in its raised position; the burner to be raised
and fixed in its raised position; the burner to be fixed in its lowest position and
the gallery also to be fixed in its lowest position.
When the parts of the lamp are in their normal positions respectively, the burner
and gallery are fixed to the reservoir of the lamp. When for the purpose of
trimming the wicks or lighting the lamp, it is necessary to give access to the wicks,
the gallery is unbolted from the burner and raised. It is supported in its raised
position by the spring bolt described. After the trimming of the wicks or the
lighting of the lamp has been effected, the spring bolt is pressed upon, when the
gallery can descend and may be bolted in its lowest position. When it is wished
to replenish the reservoir with oil, the gallery is first raised. The burner is
unbolted and raised and fixed in its raised position, to the gallery. Or the gallery
and burner are raised together. The open mouth of the reservoir is now fully
exposed and oil can be readily poured in to the required height, the surface of
the oil being visible. When the reservoir has been filled, the burner and gallery
are lowered and fastened down.
It will thus be understood that in lamps made according to my invention, the
wicks can be trimmed, the lamp lighted and the oil reservoir filled without the
detachment of any of the parts of the lamp.

page_text: The gallery and burner can however be readily removed from the reservoir
for the purpose of cleaning or repair, for the introduction of new wicks or for
other purposes.
I will now proceed to describe with reference to the accompanying Drawings the
manner in which my invention is to be performed.
Figures 12 and 3 represent vertical sections of a portion of a lamp for burning
light or volatile oil constructed according to my invention. In Figure 1 the lamp
is ready for burning, the gallery and burner being represented in their normal
positions In Figure 2 the gallery is represented raised from the burner for
trimming the wicks or lighting the lamp. In Figure 3 the burner is represented
raised (as well as the gallery) for filling the oil reservoir.
Figure 4 represents a side elevation of the gallery and burner unfastened from
the mount and Figure 5 represents a part of the same fastened to the mount;
Figure 6 represents a plan of the mount, showing the spring bolt for fixing the
gallery.
The same letters of reference indicate the same parts in Figures 1. 2. 3. 4 5
and 6.
a is the oil reservoir of the lamp, b is the metallic mount or collar cemented to
the mouth of the oil reservoir; c is the gallery carrying the chimney and globe
and the dome or deflector; d is the burner capable of a rising and falling motion
from and to the mount b. To the underside of the fixed mount b are two vertical
guide tubes e, e. connected together at bottom by the ring e². On the underside
of the gallery care two metallic rods f, f, capable of sliding steadily in the fixed
guide tubes e,je. The burner d. is also provided with tubes d², d², which slide upon
the rods ff of the gallery. On opposite sides of one of the rods are two
notches g and g², and each of the rods f is provided near its upper end with a
shallow depression . with which depressions the spring tongues 1, l. made from
the burner tubes d², d², can engage; h is a horizontal bolt carried by the mount b; the
acting end of this bolt has the shape best seen in Figure 6 and one of the rods f
passes through the said bolt. It is pressed outwards by the spring i so as to cause
it to engage with or snap into one or other of the two notches g, g², in the rod f
when the said notches are brought opposite the bolt, so as to fix the gallery either
in its lowered position or raised position. By pressing inwards the spring bolt h,
its inner acting end is withdrawn from the notch in the rod f with which it is
engaged and the gallery c is released and may be raised or lowered as herein after
described. The burner d, is not fixed permanently to the mount b but is capable
of being raised from and depressed upon the mount.
When in its depressed position, the burner d is temporarily fixed to the mount b
by the rotating ring m at the lower part of the burner. This ring m is provided
with hooks n,n. which engage with studs p, p, on the fixed mount b the said hooks
and studs somewhat resembling a bayonet joint fastening. But the burner & may
be fixed to the mount by a spring or other fastening.
When the parts of the lamp are in their normal positions respectively as shewn
in Figure 1, the burner d is fixed to the mount b by the ring fastening m, and the
gallery c, is fixed to the burner by the spring bolt h. on the nount engaging with
the upper notch g in one of the rods f.
When it is required to gain access to the wicks for trimming them or for lighting
the lamp, the gallery c. is released by pressing inwards the spring bolt h, and the
gallery c is pressed upwards with a little force into the position shewn in Figure 2,
the rods ff, sliding in the guide tubes c. c. When the gallery c has reached the
position Figure 2, the lower notch gå, in one of the rods f, is brought opposite the
spring bolt h which snaps into the said notch g², and supports and fixes the gallery
in its raised position. After trimming the wicks or lighting the lamp, the bolt is
pressed inwards. The gallery cis thereby released and may be lowered to the
burner, the spring bolt h when the gallery has reached its lowered position snapping
into the upper notch in the rod f. and fixing the said gallery as seen in
Figure 1

page_text: When it is desired to fill the oil reservoir a, the burner d is first unfastened by
turning the ring m. and the spring bolt his pressed inwards. The burner d. and
gallery c, are now raised together into the positions represented in Figure 3, the
gallery being fixed in its raised position by the bolt h snapping into the bottom
notch g and the burner being fixed to the gallery c and supported in its raised
position by the tongues l. l. falling into the depressions k., in the rods f. f as seen
in the said Figure 3. The open mouth of the oil reservoir a is now exposed and
oil may be poured into it, the surface of the oil being visible.
After filling the oil reservoir a, the spring bolt his pressed inwards so as to
release the rods f. f, on the gallery when by pressure upon the gallery, it and the
burner may be returned to the positions shewn in Figure 1 and fixed in these
positions by the spring bolt h, and fastening ring m as before described.
The gallery c and burner & may be removed from the oil reservoir for cleaning
or repair or for introducing new wicks by unfastening the ring m and pressing
inwards the bolt h, and lifting bodily the parts c. and d, from the oil reservoir.
Figures 7, 8 and 9 represent vertical sections of another arrangement of my
invention; Figure 10 is a plan of upperside of the mount fixed on the oil reservoir;
Figure 11 is a plan of underside and Figure 12-a side elevation of the gallery
and Figure 13 is a side elevation of the burner.
The same letters of reference indicate the same parts in Figures 7. 8. 9. 10.
11. 12 and 13.
In this arrangement the guide tubes depending into the oil reservoir are omitted
and short guide tubes e, e, on the inner side of the mount b. are used in place
thereof. The gallery c is provided with three rods f. g. h. and the burner d with a
fourth rod i, the said rods f. g. h. and i. sliding in the guide tubes e, e. on the fixed
mount b. The opposite rods f. g. on the gallery c. are each furnished with a
spring bolt f, g2 and the third rod also with a spring bolt h² (see Figure 10).
The rod i, on the burner d, is also furnished with a spring bolt (see Figure 10).
The rods f, g, on the gallery c. have upper and lower shoulders k, ; l, l, with
inclines in opposite directions, made upon them for retaining, in conjunction with
the spring bolts f, g, the gallery c in its raised and lowered positions. The third
rod h on the gallery is furnished with a shoulder m; without an incline, near its
lower end, which shoulder acts only as a stop for preventing the complete witli-
drawal of the gallery from the lamp, excepting when the spring bolt 2, is released.
The rod i on the burner d. has a notch at n. This notch n in conjunction with the
bolt 2, is for the purpose of supporting the burner d. in its raised position as herein
after explained.
When the gallery c and burner d. are in the lowered or normal positions
Figure 7, the gallery c, is fastened in that position by the spring bolts f² 9²
engaging under the shoulders k. k. on the rods f. g. As the gallery c, cannot rise,
the burner d, is consequently fixed down between it and the mount b.
In order to raise the gallery c for trimining the wicks or lighting the lamp, the
spring bolts f, g², are simultaneously pressed inwards so as to release the rods f, g.
The gallery c, can now be raised into the position represented in Figure 8.
On reaching this position it is supported and fixed by the spring bolts f³, g²,
suapping under the shoulders l. 1, on the rods f, g, the upward range of motion of
the said rods f, g, and consequently of the gallery, being limited by the bolt h³,
engaging with the stop shoulder m on the third rod h carried, by the gallery.
When it is wished to gain access to the oil reservoir a for filling it, the gallery c.
O together with the burner d. and rod i are raised into the position represented in
Figure 9 in which position, the bolts f, g, snap under the shoulders l, l, on the
rods fg, and the bolt 2 engages with the notch n, in the rod i, and support and
fix the gallery and burner in their raised positions.
In order to lower the gallery or the gallery and burner, it is necessary to press
5 inwards the spring bolts fg, so as to release the two rods fand g, the said
rods f, g, on the complete depression of the gallery, or gallery and burner, being
refastened by the snapping of the said bolts upon the upper shoulders k, kas seen

page_text: in Figure 7. To remove the gallery and burner from the lamp for renewing the
wicks or for cleaning, after the burner has been brought to the position Figure 9,
it is only necessary to press inwards the third spring bolt h² (see Figure 10)
thereby releasing the stop rod h, when the burner and gallery can be removed.
Figures 14 and 15 represent side elevations of a lamp, taken at right angles to
one another, containing another arrangement of my invention; Figures 16 and 17
represent the same views as Figures 14 and 15 after the gallery and burner have
been raised.
The same letters of reference indicate the same parts in Figures 14, 15, 16
and 17.
In this arrangement the burner d is furnished with two external rods e. e. and
two internal rods f, f2, and the gallery c is furnished with two tubes h. h for sliding
upon the external rods e. c. of the burner. The internal rods f, f, of the burner
slide in guide tubes 62, carried by the fixed mount b. The internal rod f. of the
burner has a notch i, and a shoulder made in it for the spring bolt l. carried
by the mount b to engage with for fixing the burner in its depressed and raised
positions respectively and the rod f2, is provided with a stop shoulder for the
spring bolt 2, to engage with to prevent the complete withdrawal of the burner
from the lamp. Each of the outer rods e. e, of the burner d, is provided with two
notches m and n for the spring bolts p. p, on the tubes h. h. of the gallery c. to
engage with for fixing the gallery in its depressed and raised positions respectively.
When the gallery c and burner d are in the lowered positions Figures 14 and 15,
the gallery c, is fixed in that position by the spring bolts p, p, engaging with the
lower notches n, n. in the rods e, e; and the burner d is fixed in its lowered
position by the spring bolt L, engaging with the notch i, in the rod f. In order to
raise the gallery c. for lighting the lamp or trimming the wicks, the spring bolts
2, p. are pulled outwards, by acting on their thumb plates, so as to withdraw them
from the notches n. n, in the rods e. e, and the gallery can now be raised into the
position represented in Figures 16 and 17, and is fixed in that position by the
spring bolts p. p, engaging with the top notches m. m. in the rods e. e, For raising
the burner d, the spring bolt 1, is pressed inwards so as to unfasten the rod f
containing the notch i and shoulder . When the burner has been raised into the
position, Figures 16 and 17, the bolt 1, snaps under the shoulder k on the rod fand
fixes the burner in its raised position.
To completely remove the gallery and burner from the oil reservoir a, it is only
necessary to press inwards the spring bolts and 12, when the combined gallery and
burner may be lifted from the reservoir for cleaning or repair or other purpose.
To remove the gallery without the burner, the screw knobs e², e², on the rods e, e,
are unscrewed and the gallery unfastened by pulling outwards the bolts p, p, when
the gallery may be lifted from the said rods e, c.
Figures 18. 19. 20 and 21 represent another arrangement for fastening the
sliding gallery last described in its raised and lowered positions respectively,
Figures 18 and 19 shewing the gallery in its lowered position and Figures 20
and 21 in its raised position.
In this arrangement, I dispense with the spring bolts 2. p, and notches m, m.
n, n. and I use in place thereof a double spring catch fastening q, r, at opposite
sides of the gallery, the said spring catch fastening somewhat resembling an
ordinary umbrella fastening. The said double fastening is situated in a longi-
tudinal slot made in the lower part of the rod e fixed to the burner d; or tubes
may be used in place of rods. The catch or shoulder parts of the double spring
fastenings when at liberty to move project beyond the slots in which they work as
seen in Figure 21. The bottom of each sliding tube on the gallery c is slotted
at h, for the catches or shoulders of the bottom fastenings q. q. to spring into when
the gallery is in the lowered position, Figures 18 and 19, the catches or shoulders
of the top fastenings r. r. being maintained within their slots in the rods e. e. by 5
the outer tubes h. h. on the gallery (see Figure 19). When it is wished to raise the
gallery c, the lower fastening of each double fastening is pressed inwards; the

page_text: gallery is thereby released, and may be raised on the rods e, e, into the position
represented in Figures 20 and 21 on reaching which position the spring fastenings
are completely uncovered and the catches or shoulders of the upper fastenings 1. 1',
are projected outwards under the bottoms of the sliding tubes h, h, and thereby
support and fix the gallery in its raised position.
In order to lower the gallery c. the catches or shoulders of the upper fastenings
r, r, are pressed inwards so as to permit of the tubes h. h. sliding downwards on
the rods e, e. When the gallery has reached its fully lowered position, the slots
h.. in the sliding tubes h. h. come opposite the lower catches q, q, of the spring
fastenings, which catches snap into the said slots and fix the gallery in its lowered
position as seen in Figures 18 and 19.
The arrangement Figures 18, 19. 20 and 21 may be modified so that the raising
and lowering of the gallery c, may be made to raise and lower the burner d. In
this modification the rods or tubes e, e, are prolonged downwards and are fixed to
the mount b instead of to the burner and tubes on the burner d are made to slide
on the rods e, c. The burner & and gallery c can be temporarily connected together
either by hook fastenings or by bolt or other fastenings. When the hooks on the
burner are disconnected from the gallery or the bolt or other fastenings are
withdrawn from the gallery, the said gallery may be raised and lowered inde-
pendently of the burner. When however it is desired to fill the oil reservoir a, the
burner and gallery are temporarily secured together by the hook or other
fastenings. By now releasing the gallery the said gallery and the burner may be
raised together and supported in their raised positions by the spring fastenings, r, 1,
in the manner before described.
When this arrangement for raising the burner is employed the sliding and fixing
rods ff, on the underside of the burner and the spring fastenings connected
therewith represented in Figures 14. 15. 16 and 17 may be dispensed with.
The burner and gallery in the arrangement represented in Figures 14. 15. 16
and 17 may be modified and hooked and bolted together in the manner described
with respect to Figures 18. 19. 20 and 21 and the combined gallery and burner
raised and lowered simultaneously when desired.
I am aware that a sliding gallery for supporting the globe and chimney and
carrying the dome or deflector, has been used prior to the date of my Patent and I
wish it to be understood that I lay no claim to a sliding gallery excepting in the
respects herein after pointed out.
Having now described the nature of my Invention and the manner in which the
same is to be performed I wish it to be understood that I claim as my Invention
