Improvements in Hand Lamps or Lanterns.
We, ALBERT WALKER and THOMAS JOHN LOACH both of Erskine Street,
Vauxhall, in the City of Birmingham, Manufacturers, do hereby declare the
nature of this invention to be as follows:-
This invention relates to detail improvements in that class of hand lamps or
lanterns known as hurricane lanterns in which heated air is conveyed from the
crown of the lantern back to the base and from thence to the burner, and consists
in the one part, in means for preventing down drafts, in another part, in means for
preventing the intermingling of cold air with the hot air, and in a further part, in
a new construction of the body.
According to our improvements, the body of the lamp made of a rectangular
shaped frame, tapering inwards from the base to the upper part and with the frame
sides coming at the angles or corners of the body, which has rabateil edges into
which taper-sided lengths of plain glass are inserted and there held, partly by the
resiliency of the metal edges, and partly by the lip of an overhanging stop tongue
forming the upper part to the body, which is surmounted by a hollow head, from
which side air tubes, directed into a hollow burner chamber surmounting the base
at the foot of the lamp, proceed.

page_text: Improvements in Hand Lamps or Lanterns.
We, ALBERT WALKER and THOMAS JOHN LOACH both of Erskine Street,
Vauxhall, in the City of Birmingham, 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:-
.
This invention relates to detail improvements in that class of hand lamps or
lanterns known as hurricane lanterns in which heated air is conveyed from the
crown of the lantern back to the base and from thence to the burner, and consists
in the one part, in means for preventing down drafts, in another part, in means for
preventing the intermingling of cold air with the hot air, and in a further part in a
new construction of the body.
According to our improvements, the body of the lamp is made of a rectangular
shaped frame, tapering inwards from the base to the upper part and with the frame
sides coming at the angles or corners of the body, which has rabated edges into
which taper-sided lengths of plain glass are inserted and there held, partly by
the resiliency of the metal edges, and partly by the lip of an overhanging stop
tongue forming the upper part to the body, which is surmounted. by a hollow
head, from which side air tubes, directed into a hollow burner chamber surmounting
the base at the foot of the lamp, proceed.
The well of the tank, which forms the base to the lamp; extends up to the
burner and is surrounded by the air chamber to which air is conveyed from the
inside crown of the lamp through the air tubes.
the burner from this said chamber.
Air for combustion is supplied to
The inside crown of the lamp or the underside of the hollow head has a
hanging air-feed tube or passage depending some distance below it, up which
passage hot air passes from the interior of the lamp to the hollow head and
from thence down the air tubes on the two opposite sides.
At the junction of the upper part of the body with the head are slit thorough-
fare ventilating passages, which intersect the hot air feed tube and have between
them and the body of the lamp a horizontal breaker, with the boundary edge
turned up lip-wise.
The rectangular body frame is provided with a door either having a glass
mirror panel inserted to form the reflector, or a panel of plain glass so as to give
light all round the lamp whilst the floor of the body part of the lamp surrounding
the burner is pierced with small holes and is convexed upon its underside and
concaved upon its topside.
In lamps constructed according to our invention the hot air is taken directly
from the interior of the lamp instead of from the crown in which the air ventilating
passages are situated.
Figure 1 of the accompanying drawings represents in front elevation a hurricane
lamp having improvements made in accordance with our invention.
Figure 2 is a side elevation of the same, showing the tapering rectangular
shape of the frame.
Figure 3 represents a cross section of the lamp upon the dotted liner, Figure 1,
-looking downwards.
Figure 4 represents another section of Figure 1, upon the dotted lines a¹, and
looking upwards.
Figure 5 is a part vertical section and part elevation of the lamp.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
a is a tapering rectangular frame, supported upon a hollow body b, forming an
air chamber and carried at the summit of a base oil tank 6', which has directed

page_text: into it, a wick tube 2, down which the wick c¹, of the burner c, supported upon the
perforated and concaved bottom 68, passes. The sides of the corners a', of the
frame have rabates or grooves a², wherein the plain glazed sides a, are slipped and
there held, so that should the glazings get broken, they admit of being readily
replaced.
The said frame has a metal back or door a³, hinged at at, and having a catch a³,.
whilst a mirror or silvered reflector a, is attached to the inner side.
e are hot air tubes, with the ends respectively terminating in the hollow-
chamber b, at the lower end and the inside of the hollow head f, of the lamp at the
other end, which crown has depending from it, a feed or inlet passage f², directed
downwardly into the body of the lamp to some distance below the ventilating-
passages f, coming between the breaker f (which is open at f³) and the cowl fo.
g is a handle, attached to the hollow head of the lamp.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what.
we claim is :-
==
First. In hurricane or band lanterns, taking hot air for combustion from the
body of the lamp by a tube depending from the hollow head and with its entrance
coming below the ventilating passages, substantially as described and set forth.
Secondly. A hurricane or hand lantern with rectangular and tapering sides,.
substantially as and for the purpose described and set forth.
Thirdly. A hurricane or hand lantern with rectangular and tapering sides, and
with the frame having clip edges and top clip stops, substantially as and for the-
purpose described and set forth.
Fourthly. In hurricane or hand lanterns, the combination with a partially open
topf, and ventilating. passages f³, of a tube 3, directed from the hollow crown
of the lamp and depending into the body of the same, substantially as and for the
purpose described and set forth.
Fifthly. The improvements in hand or hurricane lanterns, and the general.
construction, arrangement and combination of the parts of the same, substantially
as and for the purposes described and set forth.
