the nature of said invention for "IMPROVEMENTS IN TUBULAR LANTERNS
as follows:-

to be
My invention relates to certain improvements in tubular lanterns by which the
globe is hinged to the perforated disc (which carries the globe) by a double or
triple jointed hinge to the well or reservoir of the lantern, the globe being held
to the said disc by my device of a globe-guard, for which Letters Patent has been
applied for separately No 8983 of 1884.
By simply unhooking a catch on the opposite side of the hinge the globe can be
tilted over for convenience in lighting, trimming or filling.
My invention further relates to the peculiar construction of the bottom of the
air chamber and crimping the same to the lower walls of the said air chamber;
the bottom being recessed and flanged forms a deflector, and provides suitable
means for crimping the two parts doing away with all solder, which is objectionable
at that part of the lantern, thus materially cheapening the cost of manufacture.
The lantern is composed of a base or well, air tubes, and perforated disc upon
which the globe rests. A wire globe-holder and guard is secured to the disc on
each side of the globe, it is fastened to the under side of the disc and bending,
projects upwards on either side, and at the top presses against the upper part of
the globe and serves to keep it in position on the disc when the said globe is tilted
over. There is a double or triple jointed hinge which allows the globe to be tilted
over, it consists of two links the lower one being securely fastened to the base of
the lantern and the upper link hinged to the lower link and to a tube fastened to
the under side of the perforated disc thus forming a double hinge connecting the
base with the disc, for enabling the globe to be tilted over.
It will be observed
that by the addition of another link a triple hinge would be the result, but the
two aforesaid links answer the purpose and are less trouble and expense to manu-
facture. The lower edge of the upper air chamber has its sides slightly bent
inwards in order to allow the bottom to be crimped thereto; the said bottom is
stamped out of an entire piece of sheet metal with a slot cut across its centre,

page_text: a recess and a flange projecting all around from the base of the air chamber, when
the two are crimped together which does away with all solder which is objectionable
at that part of the lantern on account of its liability to melt off. In order to steady
the globe securely when in an upright position, a catch is hinged to the base, and
made to hook in an eye which is soldered to the under side of the above mentioned
disc.
The said lantern constructed as described gives a steady uniform flame at the
burner, while all springs, plates, and other devices used to hold the globe at the top
are done away with, thus materially lessening the cost of manufacture. In tipping
over the globe all that is necessary to do is simply to release the catch from the
eye, and pull the globe over, which is a great convenience for lighting, trimming
or filling.

page_text: I JOHN HENRY STONE of the City of Hamilton, in the County of Wentworth,.
in the Province of Ontario, Dominion of Canada Manufacturer 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 :—
My invention relates to certain improvements in Tubular Lanterns by which
the globe is hinged to the perforated disc (which carries the globe) by a double or
triple jointed hinge to the well or reservoir of the lantern, the globe being held
to the said disc by my device of a globe-guard, for which Letters Patent has been
granted for separately N° 8983 (84)
By simply unhooking a catch on the opposite side of the hinge the globe can be
tilted over for convenience in lighting.trimming or filling.
My invention further relates to the peculiar construction of the bottom of the
air chamber and crimping the same to the lower walls of the said air chamber
the bottom being recessed and flanged, forms a deflector, and provides suitable
means for crimping the two parts, doing away with all solder which is objectionable
at that part of the lantern, thus materially cheapening the cost of manufacture.
By reference to the drawings forming part of this Specification it will be seen
that,
Figure 1 is an elevation of my lantern.
Figure 2 is an elevation showing globe tilted over in position for lighting,
trimming or filling.
Figure 3 represents an under view of the flange and recess.
A is the base or well of the lantern B, B the tubes. O the perforated disc
upon which the globe rests, D, D, the wire globe-holder and guard secured to the
said disc on each side of the globe, it is fastened to the under side of the disc and
bending, projects upwards on either side, and at the top presses against the upper
part of the globe and serves to keep it in position on the disc when the said globe
is tilted over as in Figure 2. K is the double or triple jointed hinge which allows
the globe to be tilted over, it consists of two links h, i the lower one h being
securely fastened to the base A, and the upper link i, hinged to the link h, and to
a tube h¹ fastened to the under side of the perforated disc C; thus forming a double
hinge connecting the base A. with the disc C, for enabling the globe to be tilted
over. It will be observed that by the addition of another link to those of h and i,
a triple hinge would be the result, but the two aforesaid links answer the purpose
and are less trouble and expense to manufacture. E is the upper air chamber, the
lower edge of its sides being slightly bent inwards in order to allow the bottom a
to be crimped thereto; the said bottom is stamped out of an entire piece of sheet
metal with a slot b cut across its centre, a recess d and a flange c projecting all
round from the base of the air chamber E, when the two are crimped together as in
Figure 2. which does away with all solder which is objectionable at that part of
the lantern on account of its liability to melt oft. In order to steady the globe

page_text: securely when in an upright position, a catch e is hinged to the base A, and made
to hook in an eye f, which is soldered to the under side of the above mentioned
disc O.
The said lantern constructed as shown gives a steady uniform flame at the
burner, while all springs, plates, and other devices used to hold the globe at
the top are done away with, thus materially lessening the cost of manufacture.
In tipping over the globe as in Figure 2 all that is necessary to do is simply to
release the catch e from the eye f, and pull the globe over, which is a great con-
venience for lighting trimming or filling.
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. In a tubular lantern, a double or triple jointed hinge K, consisting of
the links h, i the former secured to the base A, and the latter link i, hinged to the
perforated disc C, and to the link h thus forming two or three hinge joints to allow
the globe to be tilted over easily for lighting, trimming or filling substantially as
specified.
Second. In a tubular lantern, the combination of the guards D, D, and double
or triple jointed hinge K, substantially as specified.
Third. In a tubular lantern, the catch e and eye f in combination with the base A
and disc C substantially as specified.
Fourth. In a tubular lantern, the body of the air chamber E and the flange c
being crimped together and forming a recess d, under the bottom a, substantially
as and for the purpose specified.
