COMPLETE SPECIFICATION,
Improvements in Tubular Lanterns.
I, JAMES HARVEY HILL, Mechanic, of No. 19, Pine Street, City of Belleville,
in the County of Hastings, Province of Ontario, Dominion of Canada, do hereby
déclare the nature of my invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to improvements in lanterns, and it has for its objects to
provide an improved construction of globe plate whereby the air which passes
through the same to the flame will be directed laterally towards the wall of the
globe with the view of keeping the glass wall cool and so as to direct the air
current to the flame from the walls of the globe inwardly to the flame; also to
provide an improved construction whereby the globe plate and globe supported
thereon may be raised or lifted to allow easy access to the wick in the act of
lighting the wick; also to provide for hinging the globe plate to the means which
permit the plate and globe to be raised so that when desired the globe may be
lifted or thrown back to allow free access to the upper portion of the wick, and
also to provide an improved construction for protecting or shielding the globe
against accidental blows which would tend to break the globe.
To the accomplishment of the foregoing and such other objects as may herein-
after appear the invention consists in the construction and in the combination
of parts hereinafter particularly described and then sought to be specifically
defined by the claims, reference being had to the accompanying drawings forming
a part thereof and in which,
Figure 1 is a side elevation of the lantern, showing in dotted lines the position
of the globe when tilted or thrown back;
Figure 2 is a side elevation at right angles to Figure 1 showing in dotted lines
the globe plate in its elevated position, also the upper portion of the lantern in
section and a part of the lower portion broken away;
Figure 3 is a perspective view of the globe plate.
Figure 4 is a perspective of an improved form of hinge for connecting the
globe-plate to the oil cup.
In the drawing the letter A designates the oil cup which is provided with
the burner collar B. The letter C designates the globe-plate upon which rests
the globe D. This plate is formed with fluted openings E which receive the air
from beneath the plate and direct it towards the wall of the globe so that the
incoming cool air will tend to cool or keep down the temperature of the globe
wall around the burner, said air or a portion of it being deflected inwardly towards
the space around and above the burner by the curved walls of the globe. The
globe-plate is secured to a vertically movable support F which is preferably com-
posed of two arms or rods G which have a telescopic connection with the guides H
supported by the oil cup, said guides preferably being made in the form of tubes
passing through the oil cup and having the arms or rods G sliding therein. This
enables the globe-plate and globe supported thereon to be raised or lifted so that
a match can be applied to the wick to light the same, the plate and globe being

page_text: pressed upwardly by the thumb and after the.wick is lighted dropped into their
normal position. The telescopic parts mentioned also afford a strong connection
between the globe-plate and oil cup and prevent any lateral shifting or move-
ment of the globe-plate. The globe-plate is preferably hinged to these support-
ing arms or rods, the hinge preferably being formed by passing a metal strip I
around the middle or connecting portion of the rods G and thence up through a
slot in the plate, the ends of the strip being bent in the form of lips to secure
the rods to the plate by a hinged connection. This hinged connection permits
the globe to be tilted or thrown back when it is desired to have free access to the
upper part of the wick.
The globe-plate also supports two shields or guards J arranged to lie on opposite
sides of the globe in the space between the opposite air tubes hereinafter described
so that the air tubes will afford a shield or guard to the globe on two sides and
the guards will afford a shield at the other two sides of the globe. These
shields are preferably formed of stiff wire bent into a loop form as illustrated
and conforming to the contour of the globe. These shields also serve to hold
the globe to the plate when the plate and globe are tilted or thrown backward.
The tubes A which supply air to the burner for the purpose of maintaining
combustion, support at their upper end a sleeve or collar L within which is a
sliding sleeve or collar M the lower end of which rests upon the top of the
globe D. This sliding sleeve is encircled by a coil spring N which has one end
connected in any suitable way with the sleeve, the other end of the spring
bearing against an inwardly projecting flange 0 at the top of the sleeve or collar L
so that the sliding sleeve will be held down by the spring. When the globe and
its plate are pressed upward this spring is contracted and when the pressure is
relieved the recoil of the spring restores the parts to their normal position. The
space between the walls of the collar L and the sliding sleeve M constitutes a
chamber T which communicates with the upper ends of the air tubes and which
also communicates with the interior of the sleeve N through openings P made
in the wall of the sleeve. Within the sleeve M is secured a cone-shaped collar Q
which forms a chamber R between it and the upper portion of the sleeve M into
which chamber air is received through openings S formed in the top of the
sleeve M, which air is prevented from going down the globe by the conical collar
and is directed through the openings P into the chamber T and thence down the
air tubes to the burner, and in the event of any very strong blast of air entering
the chamber R the excess of air may pass from the chamber T through open-
ings made in the collar L below the upper ends of the air tubes and thus the
blast is modified so as not to be too strong in passing from the air tubes to the
burner. Openings V may also be made in the lower part of the collar L adjacent
to the flange W at the lower end of the collar.
The conical collar Q by its converging walls creates a stronger upward blast of
air through the globe so that the products of combustion are more quickly carried
off, and above the conical collar Q is a deflecting plate X which is supported by
metallic strips a secured to the conical collar, and above this deflecting plate a
hood or cover is supported from the top of the sliding sleeve M, which hood
may be provided with a ring Z by which the sleeve may be lifted from engage-
ment with the upper end of the globe. The letter M designates shields which
pass only partially around in the space between the sleeves L and M so as to
cause the air blast to pass around from one side to the other of the shields M
before passing down the air tubes.
In Figure 4 the lower ends of the air tubes A' are attached to the upper
members of the hinge consisting of the ears 131 connected together by the cross-
plate C to which cross-plate the globe-plate C may be rigidly secured. The
lower member of this hinge consists of the cars B2 connected
together by the cross-plate which is rigidly secured to the top
of the oil cup A. one set of ears being hinged to the others by pins so that
the globe-plate and air tubes may be thrown backward so as to reach the wick in

page_text: lighting. The mode of attaching the globe-plate to the oil cup shown in Figures 1
to 3 of the drawing is preferred but the form shown in Figure 4 may be used
with the particular construction of globe-plate shown in Figure 3, the difference
being in the manner of connecting the globe-plate to the oil cup.
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:-
1. In a tubular lantern, a globe-plate formed with laterally extending fluted
openings for the passage of air from beneath to above the globe-plate, sub-
stantially as described.
2. In a tubular lantern, the combination with the globe-plate, of the vertically
movable support for the globe-plate, said support composed of telescopic sections,
the movable members of the sections being connected together and having the
globe-plate secured thereto, substantially as described.
3. In a tubular lantern, the combination with the globe-plate, of the vertically
movable support for the globe-plate, said support consisting of tubes arranged
opposite to each other and attached to the oil cup and two rods or arms moving
in said tubes and connected together and to the globe-plate, substantially as
described.
4. In a tubular lantern, the combination with the globe-plate, of the vertically
movable support for the globe-plate, said support consisting of telescoping
members, and a hinge connecting the globe-plate to the movable support whereby
the globe-plate and globe may be raised and also tilted, substantially as described.
5. In a tubular lantern, the combination with the globe-plate, of a vertically
movable support for the globe-plate composed of telescoping sections, and a hinge
for connecting the globe-plate and movable support, said hinge consisting of a
strip passed around a portion of one member of the telescoping sections and
through an opening in the globe-plate and having its ends bent down upon the
globe-plate to secure the parts together, substantially as described.
6. In a tubular lantern, the combination with the globe-plate, the globe, and
air tubes passing down on opposite sides of the globe, of the shields or guards
secured to the globe-plate and extended lengthwise of the globe and located on
opposite sides of the globe between the air tubes, substantially as described.
7. In a tubular lantern, the oil cup, the air tubes, the globe-plate, and the two
sets of ears each connected together by the cross-plate and one set hinged to the
other for connecting the globe plate and air tubes to the oil cup, substantially
described.
