AN IMPROVED LANTERN
Year: 1884

page_text: I, HERBERT JOHN HADDAN, of the firm of Herbert and Company, Patent Agents,
of 67, Strand, in the City of Westminster, Civil Engineer, do hereby declare the
nature of said invention for AN IMPROVED LANTERN, a communication to me
from abroad by Fr. Wlach and M. Pincoffs, of Vienna, Austria, to be as follows:-
This invention has the. object to construct a lantern which may be used in the
greatest tempest and withstand the most violent tossing without extinction so that
it may be employed as a signal lantern on express trains.
This result is obtained by a peculiarly constructed burner which renders at the
same time a glass cylinder unnecessary and by the employment of a peculiar device
for the eduction of the air.
In the body of the lantern is placed an upright cylindrical casing. At the
bottom this casing projects a little below the body of the lantern and is there
provided with holes which permit the entrance of air from the sides of the lantern,
when the latter is standing upon the ground and consequently is closed at the
bottom.
In the interior and near the lower edge, but a little above the said air holes, this
casing is provided with a flat or somewhat downwardly bent bottom perforated in
the centre, and near the upper edge the casing has a perforated inside flange.
The oil reservoir or fountain is suspended into the casing and is provided at its
bottom with a downward projecting ring, the inside dange of the casing surrounds
and approaches very closely to the cylindrical surface of this fountain which with
its perforated external flange rests upon an annular projection at the top of the
casing, so that the external flange of the receptacle is situated a short distance
above the inner flange of the casing.
The space between oil receptacle and casing serves as a passage for the entering
air. For this purpose the external flange of the oil receptacle is also provided with
holes which alternate with the holes of the internal flangé of the casing so as to
break the current of air passing through them and to prevent sudden gusts of
wind from direct access to the flame.
The receptacle and the burner are secured to an annular cover which is arranged
to be opened and closed at will and to permit the insertion of the burner through

page_text: its central opening. The conoidal shape of this cover promotes a direct delivery of
air to the burner situated immediately above the central opening of the cover.
The air thus supplied passes first around the oil receptacle, cools the same and
thereby reduces the development of gases in the interior of the receptacle.
The burner is provided with a peculiarly shaped cap h which is essentially
composed of two concave wings of the shape represented in the drawing. These
wings are connected at the bottom by means of two transverse strips ii and
converge from bottom to top as shown, an arrangement which has the effect to
flatten the flame at the top and secure a steady and constant light. The openings h¹
arranged in the wings do not only secure a reliable regulation of the delivery of
air to the flame, but serve also as safety passages for the flame, when the lantern
is thrown to the ground and falls upon one of its sides. This peculiarly shaped
cap is either supported by the stays upon the lower cylindrical part of the burner
as shown, or by means of a horizontal plate upon a projecting rim of the wick
tube, or finally is provided with a sleeve which fits to and may be placed upon the
wick tube.
The eduction of the gases of combustion is secured by the chimney, which is
composed of a cylindrical part placed on the cover of the lantern, of a bell
shaped part m arranged above the former and provided with an outwardly bent
edge m¹, and finally of a cover n placed at the top. The two latter parts of the
chimney are supported by the rods o.-The relative position of these three parts
l, m, n may be seen from the drawing. This arrangement permits a free passage
of the air from the interior to the exterior, but not in a reversed direction, and
thereby prevents an extinction of the lamp.

I, HERBERT JOHN HADDAN, of the firm of Herbert and Company, Patent Agents,
of 67, Strand, in the City of Westminster, Civil Engineer, do hereby declare the
nature of my, invention for AN IMPROVED LANTERN," a communication to me
from abroad by Fr. Wlach and M. Pincoffs, of Vienna, Austria, and in what
manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:—
This invention has for its object to construct a lantern which may be used in the
greatest tempest and withstand the most violent tossing without extinction so that
it may be employed as a signal lantern on express trains.
This result is obtained by a peculiarly constructed burner which renders at the
same time a glass cylinder unnecessary and by the employment of a peculiar device.
for the eduction of the air.
The invention is fully explained with reference to the figures of the annexed
drawing. Fig. 1 represents a vertical section of a lantern constructed according to
this invention. Figs. 2 to 5 show different views of the improved burner-cap
drawn to a somewhat larger scale.
In the body of the lantern a is placed an upright cylindrical casing b which
according to the destination of the lantern may have a conical, prismatical or any'
other shape. At the bottom this casing projects a little below the body of the
lantern and is there provided with holes c which permit the entrance of air from
the sides of the lantern, when the latter is standing upon the ground and
consequently is closed at the bottom.
In the interior and near the lower edge, but a little above the said air holes c
this casing is provided with a flat or somewhat downwardly bent bottom d,
perforated in the centre and near the upper edge the casing has a perforated inside
flange e.
fis the oil reservoir or fountain which is suspended' in the casing b and is
provided at its bottom with a downward projecting ring f"; the inside flange é of
the casing surrounds and approaches very close to the cylindrical surface of this
fountain which with its upper perforated flange f¹ rests upon an annular
projection 61 at the top of the casing b, so that the external flange of the receptacle
is situated a short distance above the inner flange of the casing.
The space between the oil receptacle and casing serves as a passage for the
entering air. For this purpose the external flange of the oil receptacle f is also
provided with holes which alternate with the holes of the internal flange of the
casing so as to break the current of air passing them and to prevent sudden gusts
of wind from direct access to the flame.
The receptacle and the burner are secured to an annular cover g, which is
arranged to be opened and closed at will and is perforated at the centre to permit
the insertion of the burner. The conoidal shape of this cover promotes a direct
delivery of air to the burner situated immediately above the central opening of the
cover. The air thus supplied passes first around the oil receptacle cools the same
and thereby reduces the development of gases in the interior of the receptacle.

page_text: The burner is provided with a peculiarly shaped cap h which is essentially com-
posed of two concave wings of the shape represented in the drawing. These wings
are connected at the bottom by means of two transverse strips ii and converge from
bottom to top as shown in Fig 3 an arrangement which has the effect to flatten the
flame at the top and secure a steady and constant light. The openings h¹ arranged
in the wings do not only secure a reliable regulation of the delivery of air to the
flame but serve also as safety, passages for the flame, when the lantern is thrown to
the ground and falls upon one of its sides. This peculiarly shaped cap is either
supported by the stays upon the lower cylindrical part of the burner as shown
in Figures 1 to 4 or by means of a horizontal plate upon a projecting rim 2³ of
the wick tube k as in Fig 5 or finally is provided with a sleeve which fits to and
may be placed upon the wick tube.
The eduction of the gases of combustion is secured by the chimney, which is com-
posed of a cylindrical part placed on the cover of the lantern, of a bell shaped
part m arranged above the former and provided with an outwardly bent edge m
and finally, of a cover n placed at the top. The two latter parts of the chimney are
supported by the rods o. The relative position of these three parts l, m, n may be
seen from the drawing. This arrangement permits a free passage of the air from
the interior to the exterior, but not in a reversed direction and thereby prevents an
extinction of the lamp.
The rods PP serve for the reception of a handle which is not shown in the
drawing.
