I, GEORGE BARKER of 77, Colmore Row, Birmingham in the County of Warwick,
Consulting Engineer & Patent Agent, do hereby declare the nature of the said inven-
tion as communicated to me from abroad by L. R. King of Waterbury in the State of
Connecticut in the United States of America :-
This invention has for its object improvements in tubular lanterns which are adapted
for out-door use and are so constructed as to be quite safe in high winds or even
hurricanes but lanterns so adapted for use are now well-known to the public. My
improvements consist in various details which greatly simplify the manner in which
the glass is held without any shake or vibration and also the simplicity with which it
may be readily moved from the burner so as to allow attention to be given to the wick
for trimming and other purposes: It is as follows:-
To the perforated plate upon which the globe is fixed I attach two bars in such a
manner that one bar is divided so as to stand half-way between each of the rarefied air
tubes. These bars may be bent to any shape but by preference to something like the
shape of the outline of the globe. To these bars I attach a circular open spring which
may be bent at one side say near one of the tubes into a bow or curve. The two ends
of the said spring after being united to the bars pass round the globe where they
are curved in an outward direction so as to allow tlie globe to pass easily out through
the points thereof when the spring is slightly extended the globe being thus held
by the circular open spring. The two guards are usually constructed of a piece of
wire doubled and carried around the outside of the base of the perforated plate
which has the effect of stiffening it but I may construct these guards from two or
more pieces of wire so that the top part would branch out into two branches for
embracing the upper part of the globe so as to hold the said globe securely without
the circular spring aforesaid. For the purpose of holding the glass from rising or
shaking in a vertical direction I attach to the upper part thereof a spring wire
which curls outwardly from the flange of the hot air receiver and then forms a
complete circle finishing with a thumb-piece at the front of the lamp. This wire

page_text: encircles the top neck of the globe and presses upon the upper shoulder or bead in
such a manner as to squeeze the globe between the perforated plate and the said
spring thus entirely preventing shake in any direction. For the purpose of removing
the globe from off the burner I connect the perforated plate to the top of a wire staple
or bridge by means of a brass or other equivalent clip which passes around the said
staple the points of the staple being soldered or otherwise secured to the top of the
oil reservoir thus forming a single hinge directly underneath the perforated plate at
about one-third of the length of the radius from the outer edge thereof. To trim the
lamp it is only necessary to press up the top or compression spring with the thumb
when the globe may be turned sideways upon the said hinge until the burner is
accessible and while in this position the glass may be removed from the open spring
clip or otherwise from the bars if the open spring clip is not used. It will thus be
seen that my tubular lamp dispenses with a great deal of the complication hitherto found
in such lamps and at the same time gives the best facility for trimming without
sacrificing any point of utility and thus the cost of production is considerably
lessened.

page_text: Improvements in Tubular Lanterns.
1, GEORGE BARKER of 77, Colmore low, Birmingham in the County of Warwick,
Consulting Engineer and Patent Agent do hereby declare the nature of the said
invention as communicated to me from abroad by L. R. King of Waterbury in the
State of Connecticut in the United States of America :-
This invention has for its object improvements in tubular lanterns which are adapted
for out-door use and are so constructed as to be quite safe in high winds or even
hurricanes but lanterns so adapted for use are now well-known to the public. My
improvements consist in various details which greatly simplify the manner in which
the globe is held without any shake or vibration and also the simplicity with which it
may readily be removed from the burner so as to allow attention to be given to the
wick for trimming and other purposes. It is as follows:-
To the perforated plate upon which the globe is fixed I attach two bars in such a
manner that one bar is divided so as to stand half-way between each of the rarefied
air tubes. These bars may be bent to any shape but by preference to something like
the shape of the outline of the globe. To these bars I attach a circular open spring
which may be bent at one side say near one of the tubes into a bow or curve. The
two ends of the said spring after being united to the bars pass round the globe where
they are curved in an outward direction so as to allow the globe to pass easily out
through the points thereof when the spring is slightly extended the globe being thus
held by the circular open spring. The two guards or bars are usually constructed of
a piece of wire doubled and carried around the outside of the base of the perforated
plate which has the effect of stiffening but I may construct these guards from two or
more pieces of wire so that the top part would branch out into two branches for
embracing the upper part of the globe so as to hold the said globe securely without
the circular spring aforesaid. For the purpose of holding the glass from rising or
shaking in a vertical direction 1 attach to the upper part thereof a spring wire
which curls outwardly from the flange of the hot air receiver and then forins a
complete circle finishing with a thumb piece at the front of the lamp. This wire
encircles the top neck of the globe and presses upon the upper shoulder or bead in
such a manner as to squeeze the globe between the perforated plate, and the said
spring thus entirely preventing shake in any direction. For the purpose of removing
the globe from off the burner I connect the perforated plate to the top of a wire
staple or bridge by means of a brass or other equivalent clip which passes around
the said staple the points of the staple being soldered or otherwise secured to the top
of the oil reservoir thus forming a single hinge directly underneath the perforated
plate at about one-third of the length of the radius from the outer edge thereof. To
trim the lamp it is only necessary to press up the top or compression spring with the
thumb when the globe may be turned sideways upon the said hinge until the burner
is accessible and while in this position the glass may be removed from the open
spring clip or otherwise from the bars if the open spring clip is not used. It will

page_text: thus be seen that my tubular lamp dispenses with a great deal of the complication
hitherto found in such lamps and at the same time gives the best facility for trimming
without sacrificing any point of utility and thus the cost of production is considerably
lessened.
In order that my invention may be clearly understood and easily carried into
practical effect I have appended hereunto two double sized sheets of drawings
upon which the various details of my lantern are shewn as well as the action
illustrated.
Figure 1 is a front elevation of the lantern in its complete form.
Figure 2 is a side elevation but on a similar scale shewing the globe K in its normal
position as when the lantern is lighted.
Figure is a similar side elevation but with the globe K turned down upon its hinge
so as to allow the lantern to be trimmed or the globe removed.
Figure 4 is a cross section through the rarefied air tubes D and globe K looking
down upon the circular open spring N which shews the clear construction of the
same.
Figure 5 is a sectional plan of the spring wire P which locks the globe' from
shaking.
Figure 6 is a plan of the perforated plate R shewing also the guard wires M. in
cross section.
Figure 7 is likewise a sectional plan on the line A. B. similar to that at Figure 4
except that the said rarefied air tubes D are not included but a modification of the
means for holding the globe is shewn therein by which I am able to dispense with the
circular open spring N.
1
From the Figures 1, 2, and 3 it will be noticed that the general configuration of
the lantern shewn is practically the same as many now in use and consists of the oil
reservoir burner T and the rarefied air tubes D which unite in the heat collecting
chamber E to which also the handle F is attached, but my invention does not apply
to these. According to my invention I hinge the perforated plate R upon the wire
staple or bridge S by means of a simple plate hinge which is turned over at ² after
passing round the said wire S thus forming a simple connection between the outer
edge and the centre of the plate R. To the perforated plate R I firmly attach two
bars M which may be constructed from a piece of wire doubled as shewn at m³ upon
the drawing and carried round at m² so as to stiffen the said perforated plate R. To.
these stiff bars M at n³ 1 attach the circular open spring N quite firmly.
This spring is carried round and formed into a bow at n¹ or into any other convenient
shape to give it sufficient elasticity to open sufficiently when required to allow the
globe K to pass out through the out turned points of the spring N. To the upper
part of the lantern I attach the spring wire P which is shewn in detail at Figure 5
being united to by the neck p¹ and having the thumb piece p² formed so that it may
be lifted by the thumb as illustrated at Figure 3 but when it is in its normal position
as shewn by Figures 1 and 2 it has the constant tendency to press the globe downwards,
upon the perforated plate R thus holding it firmly against vibration in a vertical
direction and the circular open spring N prevents any vibration in a lateral direction
thus the whole of the parts are kept steadily tied together. When it is required to
trim the lantern it is only necessary to press up the spring wire P as shewn at Figure 3
when the globe may be turned down upon its hinge, as shewn at Figure 3 when the
wick is accessible for attention. Also by pressing the globe K sideways in the
direction of the arrow at Figure 4 the circular open spring easily gives and permits
the globe to be taken out. Of course this circular spring may be opened either to the
right or left hand, as will be evident. Figure 7 merely illustrates a modification of
the means of holding the globe whereby the spring N may be dispensed with. Here
it will be seen that the bars M may be constructed so as to have spring fingers m³ as a
part thereof the bars M acting in this case as the main spring for holding the globe.
When the globe is turned down and held according to this modification it may be
removed either to the right or left that is in the direction of either arrow shewn at
Figure 7. Although I have shewn the bars or guards M constructed from a double

page_text: piece of wire it is obvious that a single piece of wire may be used with equal facility
as shewn by the supplimental figures 8 and 9.
Figure S being in broken off elevation and
Figure 9 in plan in which case the upper part that holds the globe would just be
bent into a bow to form one side T pieces m and a single piece of wire m³ to form
the other.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
First The improvements in tubular lanterns consisting of the parts by which the
globe is held securely from shaking and by which it may be easily removed substantially
as and for the purpose herein set forth and as shewn upon the drawings.
Second In tubular lanterns the bars attached to the perforated plate for the
purpose of holding an opon spring to keep the globe in place when tilted.
Third The open spring or its equivalent attached to the bars for the purpose of
holding the globe in place when tilted.
Fourth A spring formed from the bar which will grasp the globe and hold it in
place when tilted substantially as shown by Figures 7, 8 and 9 and herein set forth.
Fifth The bar attached to the perforated plate in combination with the hinge,
burner, tubes, base, and the expanding or compression spring at the top.
Sixth-The open spring attached to the bars in combination with the bar, burner,
hinge, tube, base and the expanding spring attached to the top or air chamber in
combination with the air tube.
