Improvements in Fittings for Incandescent Gas Lamps and the like.
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 improvements in fittings for incandescent gas lamps or
the like and has for its object to provide means whereby the said lamps can be, so
suspended or supported that the incandescent mantle or mantles can be protected
from the effects of vibration or shocks.
According to my invention I provide the fitting with a horizontally arranged
ball and socket joint and with a vertically acting spiral or other spring in such a
manner as to neutralize the effect of shocks or vibrations communicated to the
lamp or the like. I can also, if desired, provide the fitting with a vertically arranged
ball and socket joint.
In carrying out my invention I provide the gas pipe with a ball and socket joint
and connect thereto a vertical pipe the lower end of which is secured to a T-piece
to which is also secured a horizontal pipe provided at its end with a T-piece to the
underside of which the lamp or the like is connected and into the upper end of
which a hook is screwed the said hook being connected to the lower end of a spiral
or other spring the upper end of which hangs to a hook serving as the support proper
of the lamp.
It will be obvious that the above arrangement can be modified to suit different
forms of lamp, for instance it can be applied to an ordinary street lamp underneath
the incandescent burners or in combination with a continuation, formed of gas pipe,
on the ordinary street lamp post.
It is to be understood that the chief features of my invention are the ball and
socket joint which may be attached to a horizontal gas pipe and the vertically acting
spiral or other spring.

COMPLETE SPECIFICATION.
Improvements in Fittings for Incandescent Gas Lamps and the like.
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 improvements in fittings for incandescent gas lamps or
the like and has for its object to provide means whereby the said lamps can he so

page_text: suspended or supported that the incandescent mantle or mantles can be protected
from the effects of vibration or shocks.
According to my invention I provide the fitting with a horizontally arranged ball
joint and with a vertically acting spiral or other spring in such a manner as to
neutralize the effect of shocks or vibrations communicated to the lamp or the like.
I can also, if desired, provide the fitting with a vertically arranged. ball and socket
joint.
In carrying out my invention I provide the gas supply pipe with a ball and socket
joint and connect thereto a vertical pipe the lower end of which is secured to a
T-piece or elbow to which is also secured a horizontal pipe provided at its end with
a T-piece to the underside of which the lamp or the like is connected and into the
upper end of which a hook is screwed the said hook being connected to the lower
end of a spiral or other spring the upper end of which hangs to a hook serving as the
support proper of the lamp."
It will be obvious that the above arrangement can be modified to suit different
forms of lamp, for instance it can be applied to an ordinary street lamp underneath
the incandescent burners or in combination with a continuation, formed of gas
pipe, on the ordinary street lamp post; or it can also be applied to any upright gas
fitting or burner by reversing the whole fitting.
To enable my invention to be fully understood I will describe it by reference to
the accompanying drawing, in which:-
Figure 1 is an elevation of a fitting constructed according to my invention for
suspending a lamp:
Figure 2 is a view similar to Figure 1 of a slightly modified form of fitting;
Figure 3 is an elevation shewing a fitting adapted for carrying a street lamp; and,
Figure 4 is a similar view of a slight modification.
In the arrangement shewn in Figure 1 a is the gas supply pipe, b the ball and
socket joint fitted to the underside thereof, c the vertical pipe connected to the ball
and socket joint b and d the T-piece or elbow screwed to the lower end of the
vertical pipe c. e is the ball and socket joint fitted to the T-piece d and f is the
horizontal gas pipe secured to the ball and socket joint e. g is the T-piece screwed
to the free end of the horizontal gas pipe f and h is the spiral spring the lower
end of which is secured to a hook i upon the T-piece g and the upper end of which
is secured to the ceiling ; forming the support for the lamp.
In the arrangement shewn in Figure 2 the fitting is similar to that shewn in
Figure 1 with the exception that the spiral spring A is replaced by a pair of flat
springs h¹, A.
In Figures 3 and 4 I have shewn my invention as applied to the suspension of
street lamps. In Figure 3 the lamp A is shewn hung from a curved extension or
continuation k of the ordinary street lamp post. The ball and socket joint e is fitted
to the gas supply pipe or extension and the upper end of the spiral spring h
is suspended to a hook upon the downwardly extending upper end of the said gas
supply pipe k.
In the arrangement shewn in Figure 4 the ball and socket joint e and rigid gas
pipe fare replaced by a coiled elastic gas pipe forming a spring so as to allow
the lamp the same freedom of movement as in the case of the ball and socket
joint. In this arrangement a wire is shewn connecting the hook and the
upper end of the gas supply pipe & the said wire having for its object to support
the lamp should the spring à break. The wire is, as shewn, of such a length that
it allows the spring the necessary amount of movement.
It will be obvious that lamps suspended as above described whilst being supported
in a sufficiently rigid manner are yet allowed sufficient movement to take up or
absorb vibrations and shocks arising from traffic and other causes as the lamp is
practically suspended or supported independently of the gas supply pipe which would
communicate shocks or vibrations to the lamp or fitting.
It will also be obvious that the construction of the fitting can be modified to suit
lamps of different kinds and I wish it to be understood that the chief features of

page_text: my invention are the ball and socket joint attached to the horizontal gas pipe (or
the elastic gas pipe) and the vertically acting spiral or other spring.
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. A fitting for suspending incandescent gas lamps and the like comprising a
horizontal gas pipe secured at one end by a ball and socket joint to the gas supply
pipe and at the other end to the lamp to be suspended and to the ceiling or other
support by means of a spiral or other spring, substantially as, and for the purpose,
hereinbefore described.
2. A fitting for incandescent gas lamps and the like comprising a coiled elastic
gas pipe fitted to the gas supply pipe at one end and at the other end to the lamp
to be suspended and to the ceiling or other support. by a spiral or other suitable
spring, substantially as described.
3. The combination and arrangement of parts forming the improved fittings for
incandescent gas lamps and the like hereinbefore described and illustrated respectively
in Figures 1, 2, 3 and 4 of the accompanying drawing.
