page_text: I, LOUIS GOLDSCHMIDT, of 40, Frederiksberggade, Copenhagen, Denmark,
Wholesale Merchant, do hereby declare the nature of this invention to be as
follows:
This invention relates to a cycle lamp or lantern which can be folded together
and placed in the pocket when not in use.
It comprises two frames made of bent sheet metal, or other suitable material,
one at the top and the lower one forming the bottom of the lantern.
Into these frames are placed and held firmly the edges of a piece of canvas or
any other suitable fabric, made incombustible by being impreguated with some
suitable substance. This piece of canvas forms the four sides of the lamp or
lantern, the front side having a hole into which a frame with a sheet of glass or
mica or other transparent or translucent material is inserted.
At the back of the lantern the vertical edges of the canvas somewhat overlap
so as to enable the hand to be inserted into the interior of the lamp or lantern by
pushing aside the edges of the canvas.
The front edge of the upper frame is provided with a hinge on which a lid,
forming the top of the lantern, can turn. This lid is, at the sides, provided
with bent-down edges which overlap the upper part of the side walls, and, at the
back with a downwardly inclined edge leaving at the back an open space between
the upper edge of the back wall and the edge of the lid. The upward movement
of the lid is limited by means of small straps or the like attached at one end to
the edges of the lid and at the other end to the upper frame.
When the lamp or lantern is suspended by a ring in the lid, the lid will be
lifted as far as the abovementioned straps will permit, whereby the gases produced
by the combustion inside the lamp or lantern will be enabled to pass through
the opening between the back wall and the lid and escape in a downward direction
into the atmosphere. As this opening is situated at the back of the lautern the
draught caused by the forward movement of the cycle will not produce a dis-
turbing effect on the flame.
The walls of the lantern being made of flexible material, the lamp or lantern
may be folded in the following manner:
The frame in the front with its glass plate, is laid down on the bottom plate,
after which the lid is placed on the top of the said frame, the side walls being
suitably folded.
The dimensions of the glazed frame are proportionate to the size of the bottom
plate and the total height of the lamp or lantern.
The bottom plate is provided with a hole and with notches corresponding to
projections on a candle-holder arranged to hold candles of various lengths and
diameters. By inserting the candle-holder into the lamp or lantern from below,
the projections passing through the notches, and turning it slightly to either

page_text: the one or the other side the candle-holder will be held in place and prevented
from falling out.
The hole in the bottom plate may also at its edge be cut out so as to form
tongues that are bent-slightly upwards. This arrangement will enable a simple
candle without any holder to be pushed from underneath into the lamp or lautern
and held in place; in this case candles of various diameters may also be em-
ployed.
The bottom plate or the back wall of the lamp or lantern is provided with
holes for admitting into the interior of the lamp or lautern the necessary air
for the burning of the flame.
To enable the lamp or lantern to be attached to any cycle without any special
device for that purpose, rings are arranged on the lid aud on the bottom plate.
To these rings strings or the like are attached that can serve at the same time
to keep the lantern unfolded and attached to the cycle.
The principal advantage besides cheapness, attaching to the above described
lamp or lantern is that the same may be folded into a very small compass and
kept conveniently in the pocket until its use is required.
improvements in Cycle Lamps or Lanterns.
I, Louis GOLDSCHMIDT, of 40, Frederiksberggade, Copenhagen, Denmark,
Wholesale Merchant, do hereby declare the nature of this invention and in what
inanner the same is to be performed to be particularly described and ascertained
in and by the following statement:-
This invention relates to a eyele lamp or lantern (hereinafter called a lamp)
which can be folded together and placed in the pocket when not in use.
Fig. 1 of the accompanying drawings is a front elevation of the lamp; Figs. 2
and 3 are sections corresponding to the line 11 of Fig. 1 and showing different
forms of the bottom thereof; and Fig. 4 is a view taken at right angles to Fig. 1 of
the upper portion of the lamp.
The lamp comprises two frames and 6 made of suitable material, as slicet
metal, the frame a being at the top of the lamp and the other & forming the
bottom thereof.
In these frames are placed and held firmly the edges of a picce e of suitable
fabric, as canvas, made incombustible by being impregnated with some suitable
substance. This piece of canvas forms the four sides of the lamp, the front side
having a hole info which a frame with a sheet of suitable transparent or
translucent material, as glass or mica, is inserted.
At the back of the lamp the vertical edges of tho canvas somewhat overlap but
are not sewn or similarly attached to each other, so as to enable the hand to be
inserted into the interior of the lamp by pushing aside the edges of the piece
of canvas.
The front edge of the upper frame is provided with a hinge on which a
lid m (Fig. 4), forming the top of the lamp, can turn. The lid m is, at the sides,
provided with bent-down edges n, which overlap the upper part of the side walls,
and, at the back, with a downwardly inclined edge o leaving at the back an open
space between the upper edge of the back wall and the edge of the lid. The

page_text: upward movement of the lid is limited by means of small straps per the like
attached at one end to the edges of the lid and at the other end to the upper
frame a.
When the lamp is suspended by a ring in the lid, the lid is lifted
as far as the straps permit, so that the gases produced by the combustion inside
the lamp will be enabled to pass through the opening between the back wall
and the lid and escape into the atmosphere in the direction indicated by the arrow
in Fig. 4. As this opening is situated at the back of the lamp the draught
caused by the forward movement of the cycle will not produce any disturbing
effect on the flame.
The walls of the lamp being made of flexible material, the lamp may be folded
in the following manner:
The framed with its glass plate &, is laid down on the bottom plate b, after
which the lid is placed on the top of the frame d, the side walls being suitably
folded.
The dimensions of the glazed frame d are proportionate to the size of the
bottom plate and the total height of the lamp. The bottom plate & may, as
i
shown in Fig. 2, be provided with a hole f and with notches g corresponding to
projections on a candle-holder 9 arranged to hold candles of various lengths
and diameters. If the candle-holder be inserted into the lamp from below 80
that the projections pass through the notches g, and the candle-holder be turned
slightly to either the one or the other side, the candle-holder will be held in place
and prevented from falling out.
The hole in the bottom plate & may also at its edge be cut out so as to form
tongues (Fig. 3) that are bent slightly upwards. This arrangement will enable
a simple candle without any holder to be pushed from underneath into the lamp
and held in place; in this case candles of various diameters may be employed.
The bottom plate or the back wall of the lamp is provided with holes for
admitting into the interior of the lamp the air necessary for the flame.
To enable the lamp to be attached to any cycle without any special device for
that purpose, rings are arranged on the lid and on the bottom plate. To these
rings strings or the like are attached that can serve at the same time to keep
the lamp unfolded and attached to the cycle.
The principal advantage, besides cheapness, attaching to the lamp hereinbefore
described is that it may be folded into a very small compass and kept conveniently
in the pocket until its use is required.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed I declare that what
I claim, is:-
-
1. A folding cycle lamp comprising two frames a and b of which one is at the
top of the lamp and is provided with a cover having a rear outlet for the pro-
ducts of combustion, whilst the other forms the bottom of the lamp, and a piece
of fabric c forming the side walls of the lamp and provided with a glazed frame d
in the front wall, substantially as set forth.
2. The improved folding cycle-lamp constructed and arranged as herein before
described with reference to and shown in the accompanying drawings, whether
adapted for a candle holder according to Figs. I and 2 or for simple candles ac-
cording to Fig. 3 thereof.
