PROVISIONAL SPECIFICATION.
Improvements in and relating to Stands for Incandescent Electric
Lamps.
I, JOSEF CATHREIN, of Innsbruck, in the Empire of Austria, Hotel-keeper,
do hereby declare the nature of this invention to be as follows:-
This invention relates to stands for incandescent electric lamps and has for its
object to render such stands portable for use in rooms, so that, without liability
to entanglement of the flexible lead, they may be carried from one place to another
in the room.
A lead carrier provided on the lamp frame is made of such a length that,
together with the height of this frame and the table or the like upon which the
stand may be put, it extends beyond the ordinary height of a man, which corre-
sponds to a total height of about 2 metres; for instance, taking the height of the
table to be 0.80 metres and the lamp frame to be 0.30 metres, its height will be
about 1 metre. One end of the flexible lead is connected with the main conductor
at a point situated in the middle of the ceiling. The lead has such a length that
when stretched it will reach to a point which is at the greatest distance from the
point of attachment in the middle of the ceiling. If the lamp is moved nearer to
this point of attachment the lead becomes shorter by this length and hangs down
from the top of the carrier.
For guiding the flexible lead use may be made of an arm extending from the
middle of the ceiling and adapted to turn in the ceiling plate, so that this arm,
which receives the said lead, can be adjusted horizontally in all directions.
In lieu of the aforesaid arm I may also employ a spiral lead.
One end of the spiral lead is attached to the ceiling and the other end to the
stand of the lamp. When the lamp is placed at a distant point the spiral lead is
extended, but assumes its spiral form again on the lamp being brought nearer to
the point of attachment on the ceiling.
The lead used for the spiral is of the ordinary flexible kind with a thin steel
wire woven in, which has a spiral form.

COMPLETE SPECIFICATION.
Improvements in and relating to Stands for Incandescent Electric
Lamps.
I, JOSEF CATHREIN, of Innsbruck, in the Empire of Austria, Hotel-keeper,
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 stands for incandescent electric lamps and has for its
object to render such stands portable for use in rooms, so that, they may be
carried from one place to another in the rooms without the liability of entangling
the flexible leads.
The said invention is illustrated in the accompanying drawing in which,
Figure 1 is a diagrammatic view showing the arrangement of the device in a

page_text: Figure 2 shows an ordinary lamp stand with the new cord carrier and conducting
wire.
Figure 3 a carrier arm adapted to be used in combination therewith; and
Figure 4 represents a spirally wound conducting wire which is fixed to the
ceiling.
In carrying my invention into practice I provide a lead carrier « on the lamp
frame which is made of such a length that, together with the height of this frame
and the table or the like upon which the stand may be placed, it extends beyond
the ordinary height of a man, which corresponds to a total height of about 2 metres,
for instance, taking the height of the table to be 0.80 metres and the lamp frame
to be 0-30 metres, its height will be about 1 metre.
One end of the flexible lead b is connected with the main conductor at a point c
situated in the middle of the ceiling. The lead is made of such a length that
when stretched it will reach to a point d, Figure 1 which is at the greatest distance
from the point c of attachment in the middle of the ceiling. If the lamp is moved
nearer to this point e the lead becomes shorter by this length and hangs down from
the top of the carrier, e e Figure 1.
For guiding the flexible lead use may be made, as shown in Figure 3 of an arm f
extending from the middle of the ceiling and adapted to turn in the ceiling plate,
so that this arm, which receives the said lead, can be adjusted horizontally in any
direction.
In lieu of the aforesaid arm f I may also employ a spiral lead b as shown in
Figure 4.
One end of this spiral lead is attached to the ceiling at c and the other end to the
stand of the lamp. When the lamp is placed at a distant point the spiral lead is
extended, but assumes its spiral form again on the lamp being brought nearer to the
point of attachment on the ceiling.
The lead used for the spiral is of the ordinary flexible kind with a thin steel wire
woven in, which has a spiral form.
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-
First. In portable stands for incandescent electric lamps for use in rooms, a lead
carrier a arranged on the lamp frame and the flexible lead of which is connected
to the main conductor in the middle c of the ceiling, the length of the said lead
being such that the lamp can be placed at any desired point, in the room, substan-
tially as herein set forth.
Second. In combination with portable stands for electric lamps as described an
arm pivoted to the ceiling in the middle e of the room and carrying a flexible
lead, substantially as herein set forth with reference to Figure 3.
Third. In combination with portable stands for electric lamps as above described
a flexible lead 6 suspended from the ceiling in the middle c of the room and
wound to a spiral form, substantially as herein described with reference to
Figure 4.
Dated this 24th day of July 1893.
