Means for Raising and Lowering High-hanging Gas Lamps or
Lanterns.
I, HERMANN WINKLER, of 97, Dresdener Strasse, Berlin, in the German Empire,
Engineer, do hereby declare the nature of this invention to be as follows;-
This invention relates to an arrangement which has for its object to enable high-
hanging or other lamps, which are accessible with difficulty, to be raised and
lowered so that they can be lit or cleaned and returned to their normal positions
without being separated from the gas connections.
In carrying out the invention the gas supply pipe is advantageously provided
with a main cock and where it has to supply several lamps or lanterns, is formed
with the necessary number of branches each of which is connected to the said
supply pipe with a joint one part of which is rigidly secured to the lamp part or
bracket and the other part of which can move around the first in a vertical plane.
A pipe is screwed into the said movable part, the said pipe being provided at its
free end with a joint similar to the above described branch joint, one part thereof
being connected to the said end and the other part to a lamp or lamps. A spiral
spring is connected to the part of the joint secured to the pipe and to this a wire
rope which passes over pulleys mounted on an arm of the post or support, to a
drum provided with a crank or handle and ratchet gear and arranged at the lower
part of the lamp post. A second wire rope which is also secured to the joint passes
over a pulley and carries at its lower end a counterweight which in its lower-
most position can be securely hooked or fastened to the lamp post or support so
that the said rope also serves to hold the lamp should the first rope break.
In order to prevent the lamp, and the lamp bearing pipe from swaying or vibrat-
ing too much, spring clips and guides are provided. Each clip surrounds its pipe
when the lamp is in its uppermost position whilst the guide serves to support the
said pipe during the lowering of the lamp and prevents it when in its lowermost
position, from too great lateral movement and thereby protects the joint parts
from being subjected to too great strains.
It is obvious that the spring clip, as also the guide, can be used for similar
purposes without the employment of the ordinary lamp post or support. For
example the guide and the arm with the rollers can be secured to a wall.
Furthermore, the guide can be secured to a candelabrum and the clip to a
ceiling.
In lieu of the guide a suitably shaped double fork can be employed which
embraces the lamp bearing pipe in its highest and lowest positions and prevents it
from moving laterally.

I, HERMANN WINKLER, of 97, Dresdener Strasse, Berlin, in the German Empire,
Engineer, 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 an arrangement which has for its object to enable high-
hanging or other lamps, which are accessible with difficulty, to be raised and
lowered so that they can be lit or cleaned and returned to their normal positiona
without being separated from the gas connections.
In carrying out the invention the gas supply pipe is advantageously provided
with a main cock and, where it has to supply several lamps or lanterns, is formed
with the necessary number of branches each of which is connected to the said
supply pipe with a joint one part of which is rigidly secured to the lamp part or
bracket and the other part of which can move around the first in a vertical plane.
A pipe is screwed into the said movable part, the said pipe being provided at its
free end with a joint similar to the above described branch joint, one part thereof
being connected to the said end and the other part to a lamp or lamps. A spiral
spring is connected to the part of the joint secured to the pipe and to this a wire
rope which passes over pulleys, mounted on an arm of the post and on the latter
te a counterweight which is fitted to an endless rope passing over guide pulleys
and a drum having a handle and ratchet gear and being arranged at the lower part
of the lamp post.
In order to prevent the lamp, and the lamp bearing pipe from swaying or vibrat-
ing too much, spring clips and guides are provided. Each clip surrounds its pipe
when the lamp is in its uppermost position whilst the guide serves to support the
said pipe during the lowering of the lamp and prevents it when it is in its lowermost
position, from too great lateral movement and thereby protects the joint parts
from being subjected to too great strains.
In the accompanying drawing,
Figure 1 is a side elevation of a lamp post the lamps of which are suspended
according to the invention;
Figure 2 is a sectional view at right angles to Figure 1 shewing a portion of the
post or mast; and
Figures 3 and 4 are views of details drawn to a larger scale and hereinafter
described.
a is the post or mast having the arms a¹, a¹ and adapted to support the lamps A
as hereinafter described. In the drawing I have illustrated a post designed to take
two lamps A although only one of these is shewn.
6 is the gas supply pipe and b in the cock with which it is provided. This
pipe b is formed with a number of branches (in this case two) 6, 6; each branch 63
has hinged to it a length of gas supply pipe 6' to the free end of which is sus-
pended a lamp A. The joint which I advantageously use is shewn to a larger
scale in Figure 4 and comprises the part c which is fixed to the branch 62 of the
pipe and the forked piece c which is pivotally fitted to the part e and secured
to the branch pipe 63. A similar joint is advantageously employed for suspending
each lamp A to the pipe 63.
d is the spiral spring one end of which is fitted to the end of each branch b³
and e is the wire rope to which the other end of the spring is secured and which
passes over pulleys f, f' and is secured at its other end to a counterweight 9,

page_text: as clearly indicated in Figure 3. In the arrangement shewn in the drawing, that
is to say, where the post carries two lamps, there are two such wire ropes which
are secured respectively to the two opposite sides of the said counterweight g.
his the endless rope upon which the weight g is slung, the said endless rope
passing around the pulley h¹ at the upper part of the post and around the drum i
at the lower part of the post, the said drum being provided with a handle or
crank ¹.
jis the spring clip which is fastened to each arm a of the post and is adapted
to hold the upper end of each branch 63 to prevent the lamp swaying or vibrating
too much. k, k are guides fitted to opposite sides of the post a opposite the pipe
hinges; the branches 63 pass through these guides, as clearly shewn, and guide
them when they are released from the clips as hereinafter described.
When it is desired to light or clean the lamps the handle is turned so as to
raise the counterweight g, thereby allowing the rope e to run over the pulleys f, f'
and lower the lamps which are guided in their descent by the guides k until they
assume the position illustrated in dotted lines in Figure 1. To again raise the
lamps the handle is turned in the opposite direction and the rope e is pulled
downwards by the counterweight so as to raise the arms 6 and the lamps until
the former engage in the spring clips j.
It is obvious that the spring clip, as also the guide, can be used for similar
purposes without the employment of the ordinary lamp post or support. For
example the guide and the arm with the rollers can be secured to a wall.
Furthermore, the guide can be secured to a candelabrum and the clip to a
ceiling.
In lieu of the guide a suitably shaped double fork can be employed which
embraces the lamp bearing pipe in its highest and lowest positions and prevents it
from moving laterally.
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. Apparatus for raising and lowering suspended gas lamps comprising a branch
pipe to which the lamp is suspended and which is hinged to the gas supply pipe
so that it can move in a vertical plane, a spring clip and a guide, substantially as
hereinbefore described and illustrated.
2. In apparatus of the kind described in Claim 1 the employment of an endless
rope in which is slung a counterweight adapted to be raised and lowered by means
of a handle and, the combination therewith, of one or more ropes to which the
lamps or the branch pipes are secured, substantially as herein before described and
illustrated.
3. The combination and arrangement of parts forming the apparatus for raising
and lowering suspended gas lamps herein before described and illustrated in the
accompanying drawing.
