I, JOHN CAMERON HALLIDAY of 44 Amhurst Road, Hackney, in the County of
Middlesex Gas 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 consists of an enamelled sheet metal reflector for gas and other
lights, the reflecting surfaces of which are so formed and arranged as to cause an
approximately uniform diffusion of light therefrom both in a downward and lateral
direction and which at the same time is not liable to breakage when in use.
According to this invention the reflector, is formed of sheet metal provided with
a central dished or conical part surrounded by an annular flat or approximately
flat portion the inner and under side of these portions having a white enamelled
reflecting surface. The sheet metal reflector may be formed in one piece by
stamping, spinning, or otherwise or when of large size it may be made in sections
which are afterwards rigidly secured together by rivetting or in any other
convenient manner to form the reflector. Reflectors according to this invention
may be provided with a central outlet for heated air and products of combustion
and with means for attaching it to the gas burner or burners or such aperture may
be dispensed with in which case it is arranged to be suspended above the burner
or burners and serves as a shield as well as a reflector.
Referring to the accompanying sheet of drawings Fig. 1 is a vertical section and
Fig. 2 an under-side view of one form of my improved enamelled sheet metal
reflector, 1 being the central dished portion and 2 the outer annular flat portion
the inner and lower surfaces of which are white enamelled. 3 is a central outlet
for heated air and products of combustion. The annular part 2 instead of being
flat as shown in full lines, may be in the form of a flat truncated cone extending
either above or below a horizontal plane as indicated in dotted lines, but it is
preferred to make it quite flat. Fig. 3 is a vertical section showing a reflector
with the central reflecting portion in the form of a truncated cone and with a
central outlet 3. If desired, the reflectors shewn in Figs. 1 and 2 may be provided
with a short tube or chimney 4 as indicated in dotted lines in Figs. 1 and 2.
Fig. 4 is a central section and Fig. 5 an underside view of a reflector with its
central portion 1 of dished or curved form and without a central outlet aperture,

page_text: 5 is a ring for enabling it to be suspended above a gas burner or burners. In
this arrangement the reflector serves also as a shield to prevent smoking or
heating of the ceiling or other body above the burner or burners. Fig. 6 is a
vertical section and Fig. 7 a part plan shewing one arrangement by which a
reflector similar to that shown in Fig. 1 may be secured to a central gas supply
pipe and above the gas burners. 6 is the gas supply pipe with junction piece 7
to which the reflector is secured by screw threaded bolts 8 as shewn. Fig. 8 is a
plan or top view shewing a reflector provided with holes 9 through which take
rods that carry the gas burner or burners below the reflector. The reflector is
secured to and supported by these rods, one or more of which forms the gas supply
pipe, in any convenient manner. The reflecting surfaces of either of the portions 1
and 2 or both instead of being smooth or plain may be fluted or corrugated as
indicated in Fig. 9, which is an underside view. The reflectors instead of being of
circular form as shown in Figs. 1 to 9 may be of polygonal form as indicated in
Fig. 10 and be provided with an ornamental edge or border of any appropriate
design in one piece with the portion 2. Reflectors as shown in the drawings may
when of small size be formed by stamping or spinning from a single piece of sheet
metal, but when of large size, it may be formed in sections secured together in any
convenient manner as will be readily understood.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what
I claim is
1. An enamelled sheet metal reflector having a central dished or conical portion
and an outer annular flat or approximately flat portion substantially as hereinbefore
described and shewn in the drawings.
2. An enamelled sheet metal reflector of the kind set forth in the preceding
claim with a fluted or corrugated surface or surfaces substantially as herein before,
described with reference to and shewn in Fig. 9 of the drawings.
3. The improved enamelled sheet metal reflector herein before described with.
reference to and shewn in Figs. 1 and 2, in Fig. 3, in Figs. 4 and 5 and in Fig. 10
of the drawings,
