Improvements in the Construction of Lamp and Bracket Reflectors
for Electric, Gas, and other Lights.
I, JOHN PARKER, of Glyde Terrace, Bradford, in the County of York,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to certain improvenients in the construction and application
of reflectors and the combination of the same with electric, gas, or other illuminant
in such a manner that, the rays of light are collected and reflected in a more
efficient manner than hitherto, and thereby to more effectively utilize the light than
when the reflectors are constructed and mounted in the ordinary manner.
In carrying out my object, say with a street lamp, I fix in the upper portion of
the lamp at an inclination towards the centre of same, a continuous or a number of
reflectors of silvered glass, backed with weather resisting material for protection
of the silver and glass, or in place of glass, electro plated metal may be utilized.
A curved silvered glass or silvered metallic reflector may be fixed in the upper
portion of the lamp, in either case an opening is formed in the centre through the
inclined or curved reflector for carrying off the products of combustion, when gas
or oil is used for the illuminant; or, when the electric light is used, preparation may
be made in the top of the lamp or curved reflector, for suspending the said lamp.
At the base of the lamp I fix a globular or elliptical shaped glass or metallic
silvered reflector of suitable diameter, having a hole at the bottom of large
diameter, and a smaller one at the top, through which the gas pipe or oil burner
passes, a sufficient space being left clear of the same for air to pass for assisting
combustion.
By constructing and mounting silvered glass or electro plated reflectors within
lamps as described, with the light between the reflectors, the rays of light from the
illuminant is reflected both upon the ground immediately around the base of the
lamp, and for some distance therefrom, thereby utilizing the illuminant to better
advantage by collecting the rays and reflecting the light to a greater distance than
is the case with lamps of the ordinary construction..
It will be understood that reflectors constructed in the manner described may be
utilized on wall brackets or those secured to ceilings, in every case a globular or
other suitably shaped circular silvered reflector is secured below the lamp, and
a curved or conical reflector above same, the light being between the two.
For utilizing the electric light in shop windows or the like the reflector may be
constructed in the form of a cup, with an enlarging bell mouthed end; or the
reflector may be somewhat conical converging outwards, in any case it is made of
silvered glass or electro plated metal and may be fixed in any convenient manner.

page_text: Improvements in the Construction of Lamp and Bracket Reflectors
for Electric, Gas, and other Lights.
J, JOHN PARKER of Glyde Terrace, Bradford, in the County of York,
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 certain improvements in the construction and application
of reflectors and the combination of the same with electricity, gas and other
illuminant, in such a manner that, the rays of light are collected and reflected in
a more efficient manner than hitherto, and thereby to more effectually utilize the
light than is the case when the reflectors are constructed and mounted in the
ordinary manner.
In describing my invention in detail, reference is made to the accompanying
drawings in which
Fig. 1 represents the elevation of a street lamp suitable for burning gas and
fitted with my improvement, part of which is in section.
Fig. 2 is an elevation of a street lamp suitable for the electric light and fittel
with reflectors arranged according to my invention, and
Fig. 3 is the side elevation of a reflector in section suitable for shop windows and
the like fitted with an electric lamp.
In carrying out my object with street lamps A. I fix to the upper portion of the
lamp, a reflector B. which may be in one piece or formed of a number of pieces.
When arranging the reflectors for lainps burning gas or oil, the light is placed
in the position somewhat as shown at C. and above the light or lights C. is fixed
to the top of the lamp A. in any convenient manner, a reflector which may be
circular or of the contour of the lamp and may be of silvered glass backed with
weather resisting material for protection of the silver or silver electro plated metal,
the inner curve at B of the reflector being flatter than the outer curve, or the
portion B may be straight and incline upwards towards the centre as shown by
dotted lines Y, a hole D. of sufficient diameter in the centre being left for carrying
off the products of combustion
Below the light or lights C. I place a globular conical or curved silvered glass
backed with weather resisting material or electro silvered metallic reflector E. of
suitable diameter, having a hole through the base, and a smaller hole at the top,
through which the gas pipe F. or support for the oil vessel and burner passes,
sufficient space being left clear of the pipe or the like to admit air for assisting
combustion. The rods R. connecting the top and bottom portions of the lamp
frame being silver electro plated or covered with glass tubes silvered in the
interior.
When utilizing electricity, the light is enclosed within a glass globe J attached
to the lanp, the wires are conducted to the carbons in any convenient manner,
the reflector K. above the light being curved somewhat as shown, with a similar
reflector to E. placed below the light.
The bottom of the globe J. rests upon a cushion L. of india rubber or other
suitable soft material, the cushion is adjusted so that the weight of the globe is
carried thereby, the soft cushion resting upon a flange L' secured to a screwed bar M.
having a nut N. thereon, the bar is inserted in tube O. attached in any convenient
manner to the base of the lamp frame; on raising the globe from the cushion L
any carbon deposit is readily removed through a hole in the bottom of said globe.
By constructing and mounting silvered glass or electro plated reflectors within

page_text: lamps with the light between the reflectors as described, the rays of light from the
illuminant is reflected upon the ground immediately around the base of the lamp,
and for some distance therefrom, thereby utilizing the illuminant to better
advantage by collecting and reflecting the rays of light to a greater distance than
is the case with lamps having the lights and reflectors arranged in the manner
as hitherto.
It will be understood that reflectors constructed in the manner as described may
be utilized on wall brackets or on brackets or pendants secured to ceilings, in every
case the light is placed between the reflectors which are formed substantially as
shown and supported by attachments to the brackets or the like in any suitable
manner.
For utilizing the electric light in shop windows or the like, the reflectors P.
made of silvered glass may be constructed in the form of a cup or somewhat
conical converging outwards and having an enlarged bell mouthed end, the interior
of the reflector being fitted with an electric lamp R, the lamp and silvered reflector
being supported in any convenient manner and may be perforated in a few places
as at P, so as to admit some of the rays of light to pass to the back of the
reflector.
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. A lamp, bracket or pendant with which is combined reflectors so arranged
that the light is placed between the reflectors, the light and reflectors being arranged
substantially in the manner and for the purpose as shown and described.
2. A globe mounted in a lamp or the like between reflectors, the globe being
supported at the bottom by a cushion adjusted and arranged substantially in the
manner and for the purpose as herein before set forth.
3. A cup or conical shaped reflector P. of silvered glass combined with an
electric lamp R. placed within same for the purpose as hereinbefore described.
