PROVISIONAL SPECIFICATION.
Improvements in Regenerative Gas Lamps.
I WILLIAM EDGAR FISHER of Upper Ogle Street London W. Manufacturer
do hereby declare the nature of this invention to be as follows:-
My invention relates to the method of manufacturing regenerative gas lamps and
the fittings applicable thereto. Hitherto this class of lamp has been made in several
parts and in order to secure sound joints, asbestos or other kind of washer has been
used as a seating for the respective parts. In my method I cast the whole of the
regenerator, flange ring, and burner nozzle in one piece, thereby materially reducing
the cost of production and through having no joinings there is no possibility of
the air finding its way to the flame in any other than the desired direction. In my
lamp when first lighted the flame becomes steady and bright almost instantly, thus
avoiding the flickering unsteadiness and smell which takes place in regenerative gas
lamps as previously made. In the top fitting I provide easy access to the regulator
for cleaning or other purposes without the necessity of detaching the lamp.
Dated this 16th day of October 1893.

Improvements in Regenerative Gas Lamps.
I, WILLIAM EDGAR FISHER of Brampton Lodge, Willesden Green, in the
County of London Gentleman do hereby declare the nature of my invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
My invention relates to the method of manufacturing regenerative gas lamps and
certain fittings applicable thereto. Hitherto the coating employed in this class of
lamp has been made in several parts afterwards secured together and in order to
secure sound joints asbestos or other kind of washer has been used as a seating
for the respective parts. According to my invention I cast the whole of the
regenerator flange ring and burner nozzle in one piece thereby materially reducing
the cost of production and on account of there being no joints between the parts
there is no possibility of the air finding its way to the flame in any other than the
desired direction and moreover in a lamp made according to my invention when it
is first lighted the flame becomes steady and bright almost instantly thus avoiding
the flickering unsteadiness and smell which takes place in regenerative gas lamps
as previously made. In the top fitting I provide for easy access to the regulator
for cleaning or other purposes without the necessity of detaching the lamp as
hereinafter more particularly explained.
And in order that my said invention may be fully understood I shall now proceed
more particularly to describe the same and for that purpose shall refer to the
several figures on the annexed sheets of drawings.
Figure 1 is a vertical section and Figure 2 is a plan of a casting in one piece of
the regenerator, flange ring and burner nozzle which are respectively marked A B
& C. The other parts of the lamp can be of the usual or any suitable kind and
may be connected with the casting in the usual or any suitable way. I have shewn
the hinge lug y and lug for the fastening lever also as being cast with the aforesaid
parts although they may be otherwise attached if desired.

page_text: Figure 3 is a vertical section shewing the arrangement for affording ready access:
to the regulator without detaching the lamp. D is the regulator wich is mounted
in the position shewn between the arms E E' constituting gas passar from the gas
pipe F for supplying the main flame and the small "pilot" flame res ctively. The
passage of gas from the said pipe F for supplying the main fla e through the
regulator and to the burner by the pipe G is indicated by the arro s. H is a cover
for the regulator screwed or otherwise tightly secured in place s that it can be
readily removed without otherwise interfering with the lamp. I is the bye-pass for
gas to supply the small or pilot flame which is maintained for lighting purposes and
J is the regulating screw thereof. K is the gas cock by means of which the
supply of gas to the main flame is opened and cut off and adjusted. The part
of the pipe G shewn is a lengthening piece to which the lamp proper is secured
and which can be dispensed with when the lamp is to be situated at a higher level.
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 -
:-
1. In or for regenerative gas lamps a regenerator flange ring and burner nozzle
all formed in one piece or casting substantially as herein before described.
2. In or for regenerative gas lamps the arrangement and combination of the top
fitting and regulator substantially as hereinbefore described and shewn in Figure 3
of the accompanying drawings for the purpose described.
Dated the 16th day of July 1894.
