Complete Specification Left, 26th Sept., 1893-Accepted, 28th Oct., 1893
PROVISIONAL SPECIFICATION.
Improvements in Overhead Regenerative Gas Lamps.
I, ISAAC JOHN COLLINS, of the Lamp Manufacturing Company Nos. 12 and
14 Leonard Street, City Road, in the County of London, Lamp Manufacturer, do
hereby declare the nature of this invention to be as follows:--
In the Complete Specification of the Patent application No. 19337 of 1892 is
described the construction, with modifications, of an overhead regenerative gas
lamp arranged especially for use in the ceiling of a railway carriage. When the
lamp is so used, it is necessary to get access from the roof of the carriage to the
interior for lighting the lamp; the present invention relates to modified construc-
tion of the upper part of such a lamp so as to give ready access to the interior
without involving the lifting of much weight and the consequent risk of fracture.
For this purpose, I pass the gas supply pipe through the wall of the lamp casing
below the hinge by which the roof part of the casing is jointed to the wall, so
that, in opening the lamp by turning the roof upwards and backwards ou its hinge,
there is no disturbance of the gas pipe nor of the perforated diaphragms and air
passages below the roof: The chimney, which is hinged to the central casting in
which the regenerative passages are formed, can be turned up and back from its
seating when the roof is turned up on its hinge. In order however to save trouble
in manipulating, the chimney can be connected to the roof by a chain so as to be
raised from its seating when the roof is raised. When the chimney in either way
is raised from its seating, a taper or match can be passed through one of the
passages below the chimney to light the flame. Instead of hinging the chimney
to its seating, it may be attached permanently.to the roof to be raised with it.

COMPLETE SPECIFICATION.
Improvements in Overhead Regenerative Gas Lamps.
I, ISAAC JOHN COLLINS, of the Lamp Manufacturing Company, Nos. 12 and
14 Leonard Street, City Road, in the County of London, Lamp Manufacturer
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 :-
In the Complete Specification of the Patent application No. 19337 of 1892 is
described the construction, with modifications, of an overhead regenerative gas
lamp arranged especially for use in the ceiling of a railway carriage. When the
lamp is so used, it is necessary to get access from the roof of the carriage to the
interior for lighting the lamp; the present invention relates to modified construc-
tion of the upper part of such a lamp so as to give ready access to the interior
without involving the lifting of much weight and the consequent risk of fracture.
For this purpose, I construct the lamp as I shall describe referring to the
accompanying drawings.
Fig. 1 is a vertical section and Fig. 2 is a sectional plan on X X of Fig. 1.
Fig. 3 is a section of the circular burner.
I pass the gas supply pipe A' through the wall D of the lamp casing below the
hinge H by which the roof part C of the casing is jointed to the wall, so that, in
opening the lamp by turning the roof C³ upwards and backwards on its hinge H

page_text: there is no disturbance of the gas pipe A¹ nor of the perforated diaphragms and
air passages D D D below the roof. The chimney C, which is hinged at C³ to
the central casting in which are formed the regenerative passages A° for the
entering air and A' for the ascending products of combustion, can be turned up
and back from its seating when the roof is turned up on its hinge.
In order, however, to save trouble in manipulating, the chimney can be con-
nected to the roof by a chain F so as to be raised from its seating when the roof
is raised. When the chimney in either way is raised from its seating, a taper or
match can be passed through one of the passages A' below the chimney to light
the flame.
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 :
In an overhead regenerative gas lamp introducing the gas pipe under the hinge
of the roof, and hinging the base of the chimney to the central casting substantially
as and for the purpose set forth.
