Improvements in Tubular Lanterns.
We, SAMUEL SNELL of the firm of Snell and Company of Skinner Lane in the
City of Birmingham, Cycle-accessories Manufacturer, and GEORGE PEARCE of
147 Adderley Street in the City of Birmingham aforesaid, Foreman of Works do
hereby declare the nature of this invention to be as follows:-
This invention relates to hand lamps known in commerce as "tubular lanterns,"
consisting essentially of an oil tank base, upon which, the burner part is mounted;
and directed upwardly from the base or body of the said burner part, air tubes proceed
to an air chamber at the head of the lamp.
The globe or chimney of the said lantern, rests upon a perforated disc or gallery
surrounding the cone of the burner, and is kept in position, and protected from injury,
by elips and guards.
Our invention consists 1st, in an improved combined guard and clip, 2ndly, in a
globe carrier, and means of mounting the same, 3rdly, in a modified form of globe
carrier.
In carrying out the first part of our invention, we form the said combined guard
and clip from two lengths of spring wires, bent bow-shape at their lower parts, and
horse-shoe shape at their upper and inwardly directed parts, and with the junctions of
theu, contracted, and held together, by a clip.
The ends of the wires of the lower part of the guard thus formed, are soldered or
permanently attached to the base, or to the body of the burner part, and with the open
clip, which is adapted to embrace the upper part of globe, disposed concentric to the
burner.
Surrounding the cone of the burner, the globe rest proper, less a segment cut off,
is disposed, and upon this segment which is hinged to the base or tank, through the
intervention of uprights, one edge of the globe rests, and is thereby carried and
turned from off the burner, on the lamp requiring to be lighted, or its wick
trimmed.
Directed upwardly and bow-shaped from the supplementary rest, which is a
segment of the rest proper, are guards, surmounted by a bell-shaped annulus, which
when turned in position, over the burner, becomes coincident with, and under the
heated air chamber, leading from the upper ends of the air conducting tubes at the
two opposite sides of the lamp.
To remove the globe from off the burner, press the same outwardly from the clip,
when the said clip yields, and allows it to turn outwardly upon the segment rest joint,
formed from a lower continuation of the secondary guard, forming primarily the
carrier.
The joint is made upon a cross bar of a loop support, whilst the carrier segment
plate, and annulus, clip the rim, and upper part of globe respectively.
The rest segment may be arranged for its straight edge to rest upon the cut-off part
of the rest proper.
The modified form of globe carrier, consists of a bow shaped guard, or guard wires,
directed from top to bottom of the globe, and with the upper part terminated by a
continuous or open ring, embracing as a girdle, the said globe top, whilst the lower
part has a segment rest, carrying joints at its underside, and ends, and which is
adapted to spring and clip the rim of shade.

Improvements in Tubular Lanterns.
We, SAMUEL SNELL of the firm of Samuel Saell and Company of Skinner Lane in
the City of Birmingham Cycle-accessories Manufacturer and GEORGE PEARCE of
147 Adderley Street in the City of Birmingham aforesaid, Foreman of Works 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 hand lamps known in commerce as tubular hurricane
lanterns consisting essentially of an oil tank base upon which the burner part is
mounted, and directed upwardly from the base or body of the said burner part, air
tubes proceed to an air chamber at the head of the lamp.
The chimney or globe of the said lantern, rests upon a perforated disc or gallery,
surrounding the cone of the burner, and is kept in position, and protected from
injury, by spring clips, and wire guards.
Our invention consists 1st in an improved combined guard and clip. 2ndly in a
chimney or globe carrier or rest, also in means of mounting the same. 3rdly in an
air chamber skirting part. 4thly in the general construction and arrangement of the
parts of the lamp.
In carrying out our invention, we form the said combined guard and clip from two
lengths of spring wire, bent bow-shaped at their lower parts, and horse shoe shaped
at their upper and inwardly directed parts, and with the junctions of them, contracted,
and held together by a clip.
The ends of the wires of the lower part of the guard thus formed, are soldered or
permanently attached to the base or to the body of the burner part, and with the
open clip which is adapted to embrace the upper part of the globe, disposed concentric
to the burner.
Surrounding the cone of the burner, the globe rest proper, less a segment cut
off, is dispos, and upon this segment, which is hinged to the base, or tank,
through the intervention of uprights, one side of the globe rests, and is thereby
carried.
To remove the globe from off the burner, press the same outwardly from the
clip, when the said clip yields, and allows it to turn outwardly from a segmental
skirting wind guard forming a part of the air chamber.
A modified form of globe carrier, consists of a bow shaped guard, or guard
wires, directed from top to bottom of the globe, and with the upper part terminated
by a continuous or open ring, embracing as a girdle the said globe top, whilst the
lower part has a segment rest carrying joints.
Figure 1 of the accompanying drawings, represents partly in vertical section, and
partly in elevation, a hurricane or tubular lantern or hand lamp, constructed and
arranged according to our said invention. The said view represents the section taken
through the air tubes, which connect the head of the lamp to the base.
Figure 2 represents a side elevation of the said lamp, showing the chimney or
globe turned outwardly, from over the burner part, in order that the wick of the
lamp may be either trimmed or lighted. This said view also shows how the said
chimney or globe, rests upon only a segment of the base or gallery.
Figure 3 represents a transverse sectional view, upon the dotted lines A B figure 1,
showing the chimney or globe clip, embracing the said chimney or globe.
Figure 4 represents a plan of the open top of the chimney or globe holder, which
is embraced by an encircling holder.
Figure 5 represents a near side elevation of the lantern, with the connecting
bracket of the guard, shown broken away, so as to leave unconcealed the means for
closing the space leit between the open top of the said chimney or globe and the
air chamber above it.

Figure represents an off side elevation of the said lantern, showing the hinge
connection of the gallery or rest.
The same letters of reference indicate corresponding parts in figures 1 to 6.
a is a combined base and oil tank, surmounted by a burner part b, with air tube c
and gallery d surrounding the base of the cone of the burner part. This said gallery
is perforated, and made in segments, in manner that one of the segments remains a
fixture partially around the said burner, and the other is movable, and hinged to an
elevated bracket support, directed upwardly from the base.
The latter segment is marked d, its supporting bracket e, and the joint upon which
it turns d³.
Directed upwardly from the said hinged gallery segment, are parallel wires or
rods, terminating in a loop holder g, which embraces the upper terminal end ², of
the chimney or globe, whose base ³, rest upon both segments of the gallery,
when in its normal position, as in figure 1, but when in the turned out position
figure 2, it rests upon, and is carried by, the hinged segment part d².
'
is a box air chamber, connected to the burner air chamber 3, by the opposite air
conducting tubes c, whilst surrounding the back of the space between the top of
the chimney or globe, and the underside of the box air chamber i, is a guard or
skirting, one part of which is moveable, and the other fixed. The fixed part
is marked, whilst the moveable and semi-rotatory one is marked ³.
Thus, when the chimney or globe is required to be removed or turned outwardly
for the purpose as aforesaid, the moveable part of the said skirting, is rotated or
turned upon the outside of the fixed part i, so as to leave an opening, thus admitting
of the chimney or globe being removed.
The segmental moveable part 3, is connected to the fixed part, by a pin upon the
one, taking into a slot within the other.
On the chimney being placed in its normal position (figure 1) the moveable part
of the said lower part of the air chamber is turned so as to make a complete encircling
wind guard on the underside of the chamber as aforesaid.
The mouth of the chamber has a pierced diaphragm 2, through the slits of which,
heated air inwardly passes, and is from thence conveyed down the conducting
tubes e, to the burner.
The other side of the lamp, opposite the hinge side has combined guards and clip
supports made from parallel lengths of wire, attached at their lower ends to the
base and at their upper ends to a horse shoe, shaped clip 2 adapted to embrace
the chimney or globe below the annular flange h, near its upper end.
The lantern is provided with the usual handle 1, and other accessory parts common
to this class of lighting apparatuses.
Figure 7 represents a modified form of the upper part of the lantern-Figure 8
represents a like view, but with the chimney or globe turned outwardly.
i is the box air chamber, a rear and fixed segment of the skirting guard, and
a moveable segment of the said guard, carried by the chimney or globe holder
secured at the top of the combined guards and support wires f is a perforated
disc, at the entrance to the air chamber, and is the clip, and the guard supporting
rods, whilst h, 2, is the chimney or globe.
On the chimney or globe being in its normal position as in figure 7, the space i",
(see figure 8) at one side of the lower edge of the air chamber, is filled up by
the segmental part 3, so that the holder of the chimney or globe itself carries the
filling up piece.
Figure 9 represents another form of air chamber, constructed and arranged
according to our invention.
i is a fixed box part, a moveable cup part with the open mouth directed to
the open top of the chimney or globe.
The other part or top is perforated with holes at , wherethrough heated air
inwardly passes, and is from thence conveyed down the side air tubes c, to the
burner.
The part constitutes a rising and falling skirting, to the air chamber, so that

page_text: on the same being raised, through the intervention of a knob m, and jointed stem n,
the chimney or globe, can be turned back or taken from under the said air
chamber.
The stem n is encircled by a coiled spring o, so that by pulling up the part,
the spring is compressed, and the said part secured in a raised position, by
the turning down of the knob m, and stem adjacent to it as shown in dotted
lines.
By raising the stem knob, vertically, the spring takes the skirting wind guard of
the air chambor into its normal position as in figure 9.
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 is.
:-
First A hurricane or tubular lantern, combining or forming together the guards k
and clip, and which parts are constructed combined and applied substantially as
described and set forth.
