PROVISIONAL SPECIFICATION.
An Improved Reflector for Gas or Similar Lights.
I, JOHN JOSEPH SPOOR, of South Works, Bishop Auckland in the county of
Durham, Gas and Hot Water Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention relates to an improved reflector for gas or similar lights and is
chiefly designed for use with those of the incandescent type when arranged in groups
or clusters though it is equally applicable to the ordinary type of lights.
Hitherto in the special type above mentioned it has often been customary to
group the lights close together round the down rod or pipe and to apply the reflector
having a comparatively large central opening or flue at its top generally employed
with ordinary gas lights the result being that it is often discolored or otherwise
damaged or fractured by the heat and rendered unsightly or unfit for use.
Now in reflectors made in accordance with my invention I remedy these defects
and at the same time increase their reflecting power by forming in them above or
opposite each light a hole or aperture through which the chimney of the light is
intended to pass for a convenient distance thus permitting the free exit of heat
therefrom instead of such exit being more or less obstructed as in the old
arrangement. Thus I am enabled also to abolish the aforesaid large central opening
and substitute therefor a small hole only for the passage therethrough of the gas or
suspending pipe which I may conveniently enclose in a reflecting case or tube or
down rod connected to the reflector for supporting same on or about the burner
bracket or tap whereby a greater area is available for the diffusion of light.
I prefer to make my reflectors from sheet steel enameled and ornamented as
desired though any other material of a suitable nature may be employed.

An Improved Reflector for Gas or Similar Lights.
J, JOHN JOSEPH SPOOR, of South Works Bishop Auckland in the County of Durham
Gas and Hot Water 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 an improved reflector for gas or similar lights and is
chiefly designed for use with those of the incandescent type when arranged in groups
or clusters though it is equally applicable to the ordinary type of lights.
Hitherto in the special type above mentioned it has often been customary to group

a comparatively large central opening or flue at its top such as is generally employed

damaged or fractured by the heat and rendered unsightly or unfit for use.
Now in reflectors made in accordance with my invention I remedy these defects
and at the same time increase their reflecting power by forming in them above or
opposite each light a hole or aperture through which the chimney of the light is
intended to pass for a convenient distance, thus permitting the free exit of heat
therefrom instead of such exit being more or less obstructed as in the old
arrangement.
A reflector constructed in accordance with my invention and fitted to a cluster or
group of four incandescent gas, lights is shown in the accompanying drawing in
which Figure 1 is an elevation half in section, and Figure 2 a plan.
R is the reflector which may be a plate of porcelain, enameled sheet steel or other
suitable material, circular or angular and of convex or properly dished form, any
desired ornamentation being applied.
The reflector is provided with apertures h h through which the several chimneys c
of the burners B pass for a convenient distance the said burners being suitably
spaced apart and supported by brackets b from the suspending pipe S in the usual
manner.
To support the reflecting plate R, I use a tubular casing R' concentrically
surrounding the suspending pipe s: It may be of circular, polygonal or other form
and its outer surface is made to reflect light, its base rests on or about the burner
bracket or tap. as at 61, and its head may be splayed out as at b2 to obtain a greater
area of efficient reflecting surface in downward angular directions.
By the above described construction and fitting of my improved reflector, I am
enabled to dispense with the aforesaid usual large central opening in the reflector, a
small well fitting hole o only being required for the passage of the suspending pipe S,
also a maximum area of reflecting surface is obtained whilst the liability to
discoloration or fracture of any part is reduced to a minimum
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed, I declare that what I claim is:-
An improved reflector for groups or clusters of gas or other lights with chimneys,
consisting of a reflecting plate having a number of apertures h. h. for the passage of
the several lamp chimneys c. c combined with a centrally disposed supporting
tubular casing concentrically surrounding the suspending tube S and forming also
an additional light reflecting medium, substantially as herein described and illustrated
in the drawings.
