Improvements in Lamps or Lanterns.
I, SALOMON FALK, of the firm of Falk, Stadelmann & Company, Limited, of
83, 85 & 87, Farringdon Road, in the County of London, Manufacturers, do hereby
declare the nature of this invention to be as follows :-
My invention relates to that class of lanterns commonly known as hurricane
lanterns and it comprises improved means for holding the globe or glass in position,
for affording access to the burner and removing and replacing the globe, and for
securing and locking the parts together.
In carrying out my invention, I surround the globe horizontally with two or
more rings of wire, but instead of making these rings wholly or partly removable,
they are fixed firmly to the air tubes or other convenient part of the lantern. In
addition to the aforesaid horizontal rings I fix upon them two or more vertical
wires, either single or double, the upper end of each of which is bent into a hook
shape and adapted to engage with the upper rim of the globe. These hooks are
preferably made to clip the inner edge of the globe rim and at the same time to
exert a downward pressure, but they may also engage any other suitable portion of
the upper part of the globe. The lower end of the said vertical wires are bent
into a suitable shape so as to engage with any portion of the globe below its largest
diameter. I prefer that the wires should engage the globe at about half an inch
belows its largest diameter.
To afford access to the burner the air tubes are cut through at or about at the
level of the burner gallery so that the upper part of the lantern may be moved
away from the lower portion. One of the said tubes is advantageously provided
with a hinge so that the entire upper portion of the lantern may be turned back or
instead of fixing the hinge directly to one of the air tubes it may be fixed to rings
or other equivalent device attached to the air tubes. When the upper part is
moved away from the lower part it will be understood that the globe can be readily
removed.
To lock the two parts of the lamp together the portion of the frame opposite to
the hinge may be provided with a catch or bolt, or its equivalent, but I prefer to
employ a bail" which is hinged or pivotted to the lower part of the lantern at
opposite sides of the same. This bail or loop runs up each side of the lantern and
crosses the head or top of the same. The top portion of the bail is provided with
a spring which drops into a notch or detent in the head of the lantern, the pressure
of the said spring bail serving to lock the upper and lower parts of the lantern
securely together. At the corners of the loop and nearly or quite in a line with
the vertical portions I fix the ends of the loop or handle, so that in carrying the
lantern the spring bail is relieved from any strain or tendency to accidental
release.
The bail may have its vertical portions continued long enough to attach a
carrying handle at any desired distance above the top of the lamp and in this case
the spring portion of the bail would be carried across from side to side at a suitable
distance below the handle and so as to press upon the head of the lantern as before
described.
In practice I prefer to make this bail and spring of a single piece of wire bent
and curled so as to form hinges, eyes for handle, and pressure loop,,to engage with
the detent as hereinbefore described.

In carrying the lantern by the handle attached to the spring bail the parts are
securely held together.

COMPLETE SPECIFICATION.
Improvements in Lamps or Lanterns.
I, SALOMON FALK, of the firm of Falk, Stadelmann & Company, Limited, of
83, 85 and 87, Farringdon Road, in the County of London, Manufacturers, 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 that class of lanterns commonly known as hurricane
lanterns, and it comprises improved means for holding the globe or glass in
position, for affording access to the burner and removing and replacing the globe,
and for securing and locking the parts together.
In the accompanying drawings,
Figures and 2 are a front elevation and a side elevation respectively of a
hurricane lantern constructed according to my invention.
Figures 3 and 4 are à-front sectional elevation and a side sectional elevation of
the lower part of my improved lamp illustrating a modification; and,
Figure 5 is a view illustrating a modified construction of a detail.
Similar letters in all the figures indicate similar parts.
In carrying out my invention I surround the globe a, Figures 1 and 2,
horizontally with two (or more) rings of wires b, b, but instead of making these
rings wholly or partly removable, they are fixed firmly to the air tubes c, c (or
other convenient part of the lantern). In addition to the horizontal rings b, b I fix
upon them two (or more) vertical wire d, d, the upper end of each of which is bent
into a hook-shape, as shewn at e, e so as to engage with the upper rim of the
globe a. These hooks e, e are preferably made to clip the inner edge of the globe
rim, as shewn, and at the same time to exert a downward pressure, but they may
also engage any other suitable portion of the upper part of the globe. The lower
ends of the vertical wires d, d are bent into a suitable shape, such as that
represented at, in Figure 2, so as to engage with any portion of the globe below
its largest diameter. I prefer that the wires should engage the globe at about half
an iuch below its largest diameter.
To afford access to the burner the air-tubes are cut through, as indicated at g, g,
at or about at the level of the burner gallery h so that the upper part of the lantern
may be moved away from the lower portion. One of the said tubes is advantageously
provided with a hinge i so that the entire upper portion of the lantern may be
turned back as represented by the dotted lines in Figure 1.
Or, as shewn in Figures 3 and 4, instead of fixing the hinge i directly to one of
the air-tubes c, it may be fixed to rings j, j attached to the air-tubes c, c or to some
other equivalent device. When the upper part is moved away from the lower part
it will be understood that the globe a can be readily removed.
To lock the two parts of the lamp together the portion of one of the rings j
opposite to the hinge i may be provided with a catch k (or a bolt or its equivalent)
engaging with the other ring j.
I prefer, however, to employ a "bail" 1, 1, Figures 1 and 2, which is hinged or
pivoted at m, m to the lower part of the lantern at opposite sides of the same.
This bail or loop 1, runs up each side of the lantern and crosses the head or top n

page_text: of the same.
The top portion of the bail is formed into a spring, the middle
portion o of which drops into a notch or detent p in the head n of the lantern, the
pressure of the said spring-bail serving to lock the upper and lower parts of the
lantern securely together. At the corners of the bail 1, ♪ and nearly or quite in a
line with the vertical portions I, 1 thereof I fix the ends of the loop or handle
that in carrying the lantern the spring-bail is relieved from any strain or tendency
to accidental release.
%, so
In practice I prefer to make this bail and spring as shewn in Figures 1 and 2 of
a single piece of wire bent and curled so as to form the hinges m, the eyes r, r for
the handle, and the pressure loop o, to engage with the detent pas hereinbefore
described, but it will be obvious that the spring may be made separate from the
bail and be attached thereto in any convenient manner.
The bail may have its vertical portions continued long enough to attach a
carrying handle at any desired distance above the top of the lamp, and in this case
the spring portion of the bail would be carried across from side to side at a suitable
distance below the handle and so as to press upon the head of the lantern as before
described.
In place of the bail 1, 1, Figures 1 and 2, I sometimes make use of a catch k,
Figure 5, secured to the air-tubes c opposite that to which the hinge i is fitted.
In carrying the lantern by the handle g attached to the spring-bail 7, the parts
are securely held together.
To open my improved lanterns the catch k, Figures 4 and 5, is disengaged or the
bail,, Figures 1 and 2, pushed out of its detent p, as shewn in dotted lines in
Figure 2, when the upper part of the lantern can be turned bodily back, affording
free access for lighting and trimming the lamp, and, when in this position, the
globe a can be easily removed by simply pulling it out of the wire-frame b, d and it
can be as easily replaced.
When the parts are closed and fastened by the catch, or by the bail, the lantern
will be more secure from accidental derangement or breakage than hurricane
lanterns as hitherto constructed.
Instead of hinging the two parts of the lantern together as hereinbefore described
and shewn the upper and lower portions of the air-tubes may fit or slide into each
other and be then secured by suitable fastenings.
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 :-
1. In a hurricane lamp or lantern the combination with a number of horizontal
wire-rings adapted to surround the globe and firinly fixed to the lantern, of two or
more vertical wires having their upper ends adapted to hook onto the globe and
their lower ends bent so as to embrace or engage with the globe below its largest
diameter substantially as herein before described and illustrated in the accompanying
drawings.
2. A. hurricane lamp or lantern having its air-tubes cut through at or near the
level of the burner-gallery so as to divide the lamp into two parts adapted to be
secured or connected by suitable means, substantially as, and for the purposes,
hereinbefore described and illustrated in the accompanying drawings.
3. In a hurricane lamp or lantern the combination with the horizontal and
vertical wires band d, of the divided air-tubes c, c and the rings j, j hinged at i and
provided with the catch or fastening & as herein before described and illustrated in
Figures 3 and 4 of the accompanying drawings.
4. In a hurricane lamp or lantern the combination with the horizontal and
vertical wires band d of the divided air-tubes c, c and a bail or loop having a
spring-top adapted to drop into a notch or detent in the head of the lantern,
substantially as hereinbefore described with reference to Figures 1 and 2 of the
accompanying drawings and for the purposes set forth.

page_text: 5. The manufacture and use of a hurricane lamp or lantern, substantially as
hereinbefore described and illustrated in the accompanying drawings.
