Regenera
Year: 1887

page_text: CHARLES MAYNARD WALKER 39 Landcroft Road Dulwich Surrey Engineer do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in that class of Lamps known as "Regenera-
tive" and upon my Specification of May 26, 1887 No. 7660, and of Sep. 24, 1887-
No. 12952 for the purposes of the present invention I make a Generator in the form
of a single tube preferably of a singlo casting of metal or other substance, inside
this generator is formed a collar to receive the chimney or flue, the bottom of which
is solid, and pierced with a hole, through which the gas supply pipe passes down-
wards, and has further, lateral holes connected to similar holes in the wall of the single tubo
generator, for the passage of the products of combustion, the spaces between these connec-
tions being used as air passages upon the single tube generator. I fix the outer casing of
the Lamp, leaving sufficient room for the passage of the products of combustion to the
flue, and inside this I fix a circular deflector extending somewhat below the seating
of the glass door (hereinafter described), and upon the end of the gas supply pipe I
attach a ring burner having a double socket as described in my specification 12952-
1887-in one form of the Lamp I use the air tube of burner to hold the glass door
into its position by means of an under screw which keeps the glass up tight against
the rim of the outside case of Lamp-there I use hinged glass holder, or other
form of holding up the glass-I prefer to connect the air chamber of burner to the
inside of the generator by an open tube, passing through the solid division, so as to
obtain a supply of hot air to the under side of the flame, and further in supporting
the lamp and glass I sometimes use a harp-like form, or a pedestal arrangement in
which cases,
pass the gas supply pipe up the centre of the air tube to the gas
chamber of burner, and am thus able to detach the upper part of the Lamp from the

page_text: burner, and glass part, for the convenience of lighting, cleaning and examination-I
make the casing of the Lamp, as nearly as possible of the same diameter as the glass,
and by this means, and the use of a glass having a ground or opal surface from the
top to a convenient distance below-I do away with the shadow on the upper part of
the room and ceiling, ordinarily caused by this class of Lamp.
Improvements in Gas Lamps.
CHARLES MAYNARD WALKER 39 Landcroft Road Dulwich Surrey 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 upon my Specification 7660 1887 and of
Sep. 24-87-12952 and refers to that class of Gas Lamps known as Regenerative-
For the purposes of the present invention I make a Regenerator in the form of a single
tube, preferably in a single casting of metal, or other substance,-inside this Regenerator
is formed a collar to receive the chimney or flue-the bottom of which is solid and is
pierced with a hole through which the gas supply pipe passes downwards and has
further, lateral holes connected to similar holes in the wall of a single tube Regenerator,
for the passage of the products of combustion, the spaces between these connections
being used as air passages to the Regenerator, upon the outside of the single tube
Regenerator, I fix the outer casing of the Lamp leaving sufficient room for the passage
of the products of combustion to the flue, and inside this I fix a circular deflector
extending somewhat below the seating of the glass door-(hereinafter described)-upon
the end of the gas supply pipe I attach a burner of a ring form, having a double
socket, the gas supply being led into one, the air supply into the other.
In one form
of the Lamp Fig. 1 I use the air tube to hold the glass door into its position by means
of an under screw, which keeps the glass up against the rim of the outside case of the
Lamp, where I use a hinged glass or other form of holding the glass I prefer to connect
the air chamber of burner to the inside of the Regenerator by an open tube passed
through the solid division of burner-as described in my Specification 12952-1837
and further in supporting the Lamp and glass I sometimes use a harp-like form, or an
arrangement of a Pedestal form, in which case 1 pass the gas supply up the centre of
the air tube to the gas chamber of the burner as in Fig. 2 and am thus able to detach

page_text: the upper part of the Lamp from the burner and glass part for the convenience of
lighting, cleaning, or examination-I make the casing of the Lamp as nearly as
possible of the same diameter as of the glass, and by this means and the use of a glass
having a ground or opal band or surface from the top. I do away with the shadow.
