declare the nature of this invention to be as follows:-
-
This invention refers to improvements in Lamps upon my former specification14118-
Oct. 18. 87 and 7660-May 26, 87, for these purposes I construct a Lamp with a
central regenerator with a single tube of any suitable size, shape or material, with
lateral orifices, the upper part of which is extended.so as to form a collar to which is
attached a chimney holder, into which I insert a glass chimney, between which holder
and the regenerator is held securely the upper part of the Lamp, preferably of glass, this
may be of any form, externally, but I prefer to make it somewhat of the form of the
cup of an acorn, with a neck extending a convenient distance from the shoulder, to the
regenerator I attach a socket which fits loosely over the tip of the ring burner,
described in my Specification of 12952 Sep. 24. 87 which burner is fitted to the gas
supply in the same manner as an ordinary burner and is further fitted with a gallery
to support the under glass, the top of which fits up to the shoulder of the upper glass,
with the exception of a sufficient space for the admission of air-which I regulate by
suitable projections on the upper glass, preventing it coming into close contact with the
lower glass or by a convenient number of holes-the air entering at this point
impinges against the neck of the upper glass, which thus forms a deflector, the air receiv-
ing an impetus downwards from whence, after it has become heated rises to the under
surface of the flame, by these improvements I am able to make nearly the whole of the
exterior of the Lamp of transparent materials entirely preventing shadows on the
ceiling or walls of the apartment-1 sometimes modify the above arrangement by
making the lower glass larger than the upper, and fitting a ring or band with orifices
for the admission of air. The action of the improved Lamp is as follows-the gas
being ignited at the burner, and the lower glass placed in its position, the upper part
of the Lamp, at the point where the socket is fitted to regenerator, is placed over the

superheated.
COMPLETE SPECIFICATION.
Improvements in Gas Lamps.
CHARLES MAYNARD WALKER 39 Landeroft Road Dulwich Surrey Engineer do
hereby declare the nature of this invention and in what manner the same is to
te performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements upon my former Specification No. 14118-
87 for this purpose I construct a Lamp with a vertical Regenerator of a single tube
of any suitable size shape or material, with lateral orifices the upper part of which is
extended so as to form à collar, to which is attached a chimney holder, into, which is
inserted a glass or other chimney, between which holder and the Regenerator is held
securely the upper part of the Lamp-preferably of Glass-this may be of any form
externally but I prefer to make it somewhat of the form of the cup of an acorn
inverted the lower portion of which is narrowed and extended so as to form a
deflector of the air current to burner-to the Regenerator I attach a socket which fits
loosely over the top of the ring burner described in my Specification of 12952-87-
which burner is fitted to the gas supply in the same manner as an ordinary burner and
the burner is further fitted with a gallery to support the under glass-the top of the
latter fitting up to the upper glass with the exception of a small space for the
admission of air which space is regulated by screwing up or down the gallery
supporting the glass-the air entering through this space impinges upon the lower
and extended portion of the upper glass which thus forms a deflector-the air also
receiving an impetus downwards, from whence after it has been heated it rises to the
under surface of the gas flame-by these improvements I am able to make nearly
the whole of the exterior part of the Lamp of transparent materials-thus preventing the
shadows upon the ceiling or walls of the apartment-I sometimes modify the before-
mentioned arrangement by making the lower glass larger than the upper and fitting a
ring or band (with orifices for the admission of air) encircling the upper glass deflector
and resting upon the edge of the lower-the action of the Lamp is as follows-the gas

page_text: being ignited at the burner and the lower glass placed in its position-the upper part
of the Lamp, at the point where the socket is fitted to the Regenerator, is placed over
the burner the Lamp being supported by the burner and fitting-the heat from the
flame causing a draught in the chimney draws external air into the regenerator and
to the flame, also drawing in a portion between the upper and lower glasses, as before
described, and at the air orifices of the burner, from all of which points the air on its
way to the flame becomes superheated-The herewith Drawings further show the
arrangements of the parts of the improved Lamp-Fig. 1-A upper glass of lamp
B, lower glass of Lamp-C-Regenerator D-chimney-E chimney holder F ring
burner G-gallery to hold glass-Fig. 2-H Band or ring with air holes.
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
The arrangement and combination of parts substantially as herein described and
with reference to Figs. 1 and 2 of the annexed drawings.
Dated this 23rd day of November 1888.
