Improvements in Suspension Gas-lamps, Chandeliers, and the like.
I HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows:-
-
The improvement in connection with suspension gas-lamps, chandeliers, and
the like, consists in that the burner and the gas-supply pipe in the form of a
suspension bracket are so connected together and arranged as to remove the
latter from the influence of the direct heat and gases of combustion passing up
through the chimney of the lamp.
To this end the supporting point or socket of the gas-supply pipe is arranged
at the side of the chimney and the arm or gas connection pipe from the said
support or socket is divided laterally into two branch pipes, passing downward
by the side of the chimney. If preferred these two branch-pipes may branch
off from the support separately. They are thus arranged sideways of upper
opening or mouth of the chimney and out of the path of the gases and vapours
emitted by the chimney so that the brass, of which they are usually made, does
not become blackened thereby.
As the improved arrangement does not permit the globe being placed in
position from above a supporting cup is provided to carry the said globe and
such cup is adapted to be easily removed to allow of the removal of the globe
from, or replacing it on the lamp from below. This may be effected by form-
ing the cup with an ordinary screw socket for screwing upon a screw-threaded
extension of the lower end of the burner support, or in any other convenient
manner. The novelty in connection with this arrangement is that the inner
diameter of the screw-socket of the cup is larger than the handle of the gas
cock or tap and that this handle is rigidly attached to the plug of the tap.
Obviously therefore the globe with its cup can be removed or replaced by pass-
ing the socket over the handle thus rendering it unnecessary to make the said
handle removable.

Improvements in Suspension Gas-lamps, Chandeliers, and the like.
I HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, 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:-
The present invention relates to improvements in suspension gas-lamps,
chandeliers and the like and it more particularly refers, first, to the arrangement
and connection of the gas supply pipe or pipes with the burner, and second, to
the arrangement of the support of the globe. The objects of the improvements
are to remove the gas supply pipe or pipes from the influence of the direct
heat and products of combustion passing up through the chimney of the lamps
or burner respectively, thus preventing them becoming blackened or discoloured
and also to afford facilities for the easy removal and replacing of the globe
and its support on the lamp or burner from below.
I attain these objects by the arrangement and combination of parts illustrated
in the accompanying drawings, in which
Figure 1 is a front elevation, partly in section, of an incandescent gas-lamp
constructed and arranged in accordance with my invention; Figure 2 is a side
elevation, partly in section, of the gas-lamp shown in Figure 1.
The supporting bracket or socket a of the gas-supply pipe is so arranged
as to be at the side of the chimney b, for instance it may extend from a wall w
as shown in Figure 2; the gas supply pipe from the said support or socket a
branches into two lateral pipes d d which are connected with the casing h of
the stop cock or the burner respectively by pipes passing downward by
the side of the chimney. If preferred the two branch-pipes d d may branch
off from the support a separately. The pipes leading the gas to the burner
are thus arranged side-ways of the chimney or of the upper opening or mouth
of the chimney respectively and out of the path of the gases, the flame and the
products of combustion passing through the chimney so that the brass, of which
these gas supply pipes are usually made, does not become blackened or dis-
coloured.
As this arrangement does not permit the globe y being placed in position from
above, a supporting cup f is provided to carry the said globe, such cup being
adapted to be easily removed to allow of the removal of the globe from, or re-
placing it on, the lamp from below. This may be effected by forming the cup
with a screw socket f for screwing it upon a screw-threaded extension h¹ of
the stop cock casing, or in any other convenient manner. The salient feature
of this arrangement is, that the inner diameter of the screw-socket of the cup
is larger than the handle e¹ of the plug or cone e of the gas cock, and said
handle is rigidly attached to the plug of the said gas cock or tap. Obviously
therefore the supporting cup f and the globe g may be removed or replaced by
passing the socket f¹ over the handle e¹, thus rendering it unnecessary to make
the said handle e removable or detachable.
It is obvious that instead of supporting the globe, chimney, burner and their
accessories by a pair of suspension arms, only one such arm may be employed
to pass between the globe and chimney and to act both as a suspension arm
and a gas-way.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated
to me by my foreign correspondent, I declare that what I claim is:-
(1) In suspension gas-brackets, chandeliers and the like, the combination

page_text: with a bracket or socket forming the terminal of a gas-conduit, of one two or
more arms or branches passing down between the globe and chimney and con-
stituting the support for the said globe, chimney, burner and accessories, with
one or more of the said suspension arms serving as gas ways to the said burner,
substantially as and for the purpose herein described and set forth.
(2) A suspension gas lamp, chandelier or the like, comprising depending
side members (one or more of which may be gas ways) hanging at their upper
ends from the terminations of the branches of a bifurcated bracket, and con-
nected at their lower ends to a stop cock casing, to which a globe supporting
gallery is detachably secured in such a manner as to admit of the globe being
introduced into position from underneath, substantially as and for the purpose
herein described and set forth.
Dated this 23rd day of December 1899.
