IMPROVEMENTS IN TUBULAR LANTERNS
Year: 1884

page_text: I, JOHN HENRY STONE, of Mary Street, Hamilton, in the County of Wentworth,
Province of Ontario, Dominion of Canada, Manufacturer do hereby declare the
nature of said Invention for "IMPROVEMENTS IN TUBULAR LANTERNS," to be as
follows:-
According to my Invention I employ a globe holder for securing the globe at the
top. Heretofore the objection to tubular lanterns was the spring which secured the
globe at the top made it difficult to remove the globe and replace it when necessary,
but by my device a very handy convenient and simple arrangement for securing
the globe in its place at the top is provided. I use three wires connected to a ring
which surrounds the top of the globe, which may be open on one side to allow of
expansion by heat, they pass through openings in the bottom of the air chamber,
are bent at right angles in the air chamber, and their upper portions uniting and
passing up through the top of the lantern terminating in a ring for raising it.
A spiral spring in the air chamber surrounds the upper parts of the wires, and
presses the ring down on the globe. I joint the tubes at the commencement of the
lower elbows and affix a sliding plate to the end of each of the upright tubes which
is made to move in a vertical groove guide plate affixed to the horizontal portion of
the tubes, by which means, when the lantern handle is drawn upwards, the upper
part of the lantern with the globe can be elevated above the burner, for any desired
purpose, such as lighting, trimming and filling..
The device of a sliding plate and a grooved plate may be reversed, that is to say,
the grooved plate can be affixed to the outer part of the vertical sections of the
tubes, and the sliding plate affixed to the lower section, and when so arranged the
tubes are cut above the elbows, and the upper part of the lantern and globe may be
elevated above the burner in the same way by simply pulling upwards on the
handle.
A suitable locking device is attached to the well or reservoir, and made to catch
on the wire tube brace or to a loop attached to the end of the vertical section.
The globe guard is affixed permanently to the perforated disc upon which the
globe rests, which is calculated to remove the old form of guards which were
slipped over the side tubes, and they not being fastened to the lantern had to be
lifted off every time the globe was removed for lighting, trimming, and filling,
frequently they were forgotten to be replaced, and were liable to become broken or
lost, and thus were objectionable. My said device is stationary and firmly affixed
to one portion of the lantern but can be removed with the globe and its supporting
disc, whenever it is necessary to remove them, at the same time the globe can be
removed with the guard.
The upper sections of the side air tubes enter an air chamber at the top of the
lantern and there are lower tube sections. The glass globe is surrounded by an
annular ring of wire which surrounds the top of the globe it may be open to allow

of expansion of the globe by heat. Three or more wires or sheet metal strips pass
through the bottom of the air chamber by holes, and are bent at right angles
uniting and passing up through the top of the lantern terminating in a ring for
raising it. On the lower end of the ring is a flange or cap to prevent the spring
drawing it down too far. A spring in the air chamber surrounds the vertical
portion of the wires and presses an annular ring upon the top of the globe to hold
it in its place.
A disc is made to surround the wires at the base of their junction and affixed
thereto and provided with a small opening through which the ends of the spring
pass to retain it in its place. This device does away with the spring that has been
used heretofore and.which was objectionable, in that it was unhandy to remove the
globe.
.
The horizontal tubes are jointed. There is a slide plate attached to the end of
the vertical tubes and made to slide in a grooved plate fastened to each end of the
horizontal tubes. A vertical slot is cut in the grooved plate as well as through
braces respectively which are inade to strengthen the grooved plates. There is a
wire bent around the base of the burner, and passes through the slot in each
grooved plate and brace, and their outer ends are fastened to the slide plates
respectively and this wire also supports a perforated disc which supports the globe,
this device retains the globe in place when it is elevated above the burner.
The upper and lower, parts of the lantern are held together by any ordinary
locking device such as an eye affixed to the right elbow of the tube, and a hook
fastened to the 'base, which is meant to catch in the said loop or eye when the
upper and lower tube sections are connected.
The said hook is thrown off the loop or eye when the upper section of the
lantern with globe are raised up above the burner which is done simply by an
upward pull on the handle with one hand while the base is held down with the
other.
The sliding arrangement could be placed on the outside of the tubes by jointing
the tubes above the lower elbows and soldering a three sided plate on the outside
of the said tubes so as to leave space enough for a spring sliding plate to pass
through each plate being secured to the lower section of the tubes, the wire in
this case being soldered or otherwise secured to the ends of the upper section of the
tubes, and a locking device made to hold the two sections of the tubes together.
In raising the upper part of the lantern the hook is thrown off the wire and
raised for lighting trimming and filling. A small tube is inserted in the mouth of
each lower tube section and covered by the lower ends of the upper tube section,
when the said upper and lower sections are closed or connected.
The globe guard is made of two pieces of wire about the size known as Nº 12
and bending them.
shaped and affix them, one on each side to the under
side of the perforated disc on which the globe rests the upper part of each guard
will possess elasticity and spring to press sufficiently against the globe. The guard
is curved at the sides outwards to the general form of the swell of the lower part
of the globe. The upper horizontal portion of the guard is curved inwards at its
central part to conform to the rounded surface of the globe against which it presses
it will thus be seen that the globe disc and globe guard are firmly united and when
the said disc is in place the guard is stationary and cannot be removed unless the
disc and globe are taken off. Having the guard stationary and yet removable
when desired overcomes the objections to the loose guard placed around the outside
of the tubes as now employed.

Province of Ontario, Dominion of Canada Manufacturer do hereby declare the
nature of said invention for "IMPROVEMENTS IN TUBULAR LANTERNS" and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-

in the mouth of cach lower tube section B and covered by the lower ends of
the upper tube sections A, when the said upper and lower sections A and B are
closed or connected.
"
The globe guard is formed by taking two pieces of wire about the size known
as No 12 and bending them
shaped, and affixing them, one on each side to
the under side of the perforated disk H on which the globe rests the upper part of
each guard will possess elasticity and spring to press sufficiently against the globe C.
Fig 5 shows one half of the guard attached to the disc H while J J Fig 9 shows the
perspective view of both sides each fastened to the disk H, and curved at the sides
outwards to the general form of the swell of the lower part of the globe. The
upper horizontal portion all of the guard is curved inwards at its central part to
conform to the rounded surface of the globe against which it presses, it will thus
be seen that the globe disk H and globe guard J J are firmly united and when the
said disk is in place as at Fig 5 the guard is stationary and cannot be removed
unless the disk and globe are taken off. Having the guard stationary and yet
removable when desired overcomes the objections to the loose guard placed around
the outside of the tubes as now employed.
