Winsdor Lantern (With New Gas Industry Fitting)
A new low-light conversion unit to conform to the lighting restrictions. Designed by the
Gas Light and Coke Company in their Watson House laboratories. It gives the allowable ARP light output, but does so
with about a third of the gas used in earlier units, and requires only about a fourth of the amount of metal used for standard
fittings. Designed for war-time use, the unit is capable of meeting a variety of peace-time conditions as it is applicable not only
to ARP street lighting but for the illumination of bollards or street signs where a source of low intensity is required. The
light output is secured with a gas consumption of 0.6/0.7 cu. ft. per hour, as compared with the 1.6 cu. ft. per hour with the
standard ARP fitting. Bearing in mind that under existing labour conditions it is not possible or economical to light and extinguish
ARP fittings each day, the overall economy in gas is considerable, both for the local authority and from the point of view of
national fuel economy. Four of the new units can be made out of the metal required to produce a single unit of the existing type.
In place of the usual bunsen burner and standard mantle, a non-aerated burner and specially designed mantle are employed.
The ordinary bunsen burner with mantle is unsuitable for gas rates of the order of 0.5/1 cu. ft. per hour. (It is difficult to
make small mantles of robust constuction and the expense involved in making aerated burners with controls machined to the required
accuracy is too high. At low gas rates, the performance of a bunsen burner is liable to be adversely affected by foreign matter
carried in the gas stream or primary air - this leads to instability and considerable variation in the total light output from
the source.)
A non-aerated burner with a fine orifice operates at the full service pressure of the gas. This rat-tail
burner, with a non-luminous tip, is allowed to impinge on the mantle of special design and produce a suitable source
of light for ARP and other purposes. Satisfactory results are obtained with the flames directed nearly vertically
upwards onto a flat mantle. A 3-hole burner is used and found to be the most satisfactory, and the division of the
gas rate into 3 ensures that each flame is highly aerated. The distribution of light is obtained by surrounding the
light source with a glass chimney, on which is stencilled a mask of the necessary design to obscure the unwanted
light flux and control the candle power in the required directions.

rochester / rochester suspension unit
The firm claimed to be the originators of this type of lantern. Available in "upright" or "suspension" options. Could take 4-8 mantles, with either single or
dual supplies, and with clustered or "in-line" arranagements. Could also be
supplied with either: "Multi-ray" reflector; "K" or "S" type Directional Reflector; Holophane
Dish and or Band refractors.
Clock controller, governor and/or controller could be fitted in the base. Was the lantern of choice
for the City of Westminster and was installed on the Great West Road in 1936.
Could be modified to comply with British Standard Specification BS/ARP37 so as to convert the lantern
for war-time use. In this configuration, it could only output 0.0002 foot candles.
This was one of the models selected for immediate post-war production.
In 1945,
it has a variety of applications in either Upright or Suspension form and can be applied
in most street lighting scheme. It meets the requirements of the Ministry Of Transport's
Final Report. The specially constructed stormproof casing and remarkably high efficiency has produced a
splended record of trouble-free service with a minimum of maintenace costs.

london c pattern lamp
The London lamp was desgined to break away from the conventional shape of gas lamps and
to incorporate within the lines of the unit all the necessary reflector equipment. The great advances made in
the manufacture of heat resisting backing for mirrors enables mirror glass reflectors to be employed with consequent
high reflection efficiency. Ventilation on the Venturi flue principle not only reduces the overall height of the lamp,
but in conjunction with the patent improved air-gas mixing arrangements increases the lumen output of the light
source. The "C" pattern lamp incorporates within the design of the unit accommodation for the clock controller,
pressure governor and igniter. The reflector system is similar to the "B/2" pattern.

london b/2 pattern lamp
The London B/2 was described as new in 1937, although it was being installed in 1936 and described
as "widely used." It replaced the picture of the "C" pattern lamp in "The London Lamp" advertisement in
September 1936. (The B/2 probably designates
the use of number 2 mantles). It was of simplier construction and more universal application. A reflector system
similar to the "C" pattern lamp is incorporated. The design of the reflector equipment is such that
the candle-power at angles very near to, or above, the horizontal, is low; by this means glare in the normal
line of vision is reduced to a minimum and the flux utilisation of the source is high. The only adjustment provided on
the reflectors raises or lowers the angle of maximum intensity to suit various spacing height ratios, and to obtain
a compromise between reasonable test point illumination and road surface brightness.
It was described as "self-focussing"
and was fitted with a unique reflector system which gave excellent visibility and reduced glare. The use of shaped glass reflectors
gave a very high degree of light control without undue absorption.
A low-pressure unit with a streamline flow superheater carrying six, eight or twelve No. 2
mantles in alignment. Special mirror trough reflectors with heat resisting backing are used
to give a wide distribution up and down the road. The "Venturi" type flue reduces the height
of the lantern, and ensures steady burning udner the most adverse weather conditions. The
burner incorporates a novel air control resulting in a very efficient light output.
For use in "busy" streets. It was exhibited at
the APLE's 1937 conference at a spacing of 135' staggered, 25' height and giving a Class "D"
classification. The lamps were adjusted to give a good compromise between surface brightness and horizontal
illumination. In 1937, the lantern is available in four sizes. The mantles are arranged
in line, the directional equipment consisting of special heat resisting mirror
glass troughs of parabolic section. The reflector system is held in a rigid frame
which also carries a compensating plane refelctor. The function of this compensating
reflector is to redirect the light that would otherwise be wasted above the horizontal
on the road surface adjacent to the lamp.
Its output was increased in 1938 by a new burner design which gives an exact air adjustment and
the optimal gas-air mixture for gases of different composition. By 1945, the lantern had been extensively used,
now being built in accordance with the MOT's Final Report for Group "A" lighting. Has a special
mirror glass optical system which can easily and accurately adjusted to suit any change of
gradient in the road. Alternative Special Reflector Systems could be supplied to
give either a low cut-off system or a back refelctor for unilateral distribution.
Adjustment of reflector system in situ: The rigid frames are pivoted
and the angle of maximum intensity can be adjusted locally by
means of two lead screws shown at B, B, which pivot the frames
independently. The reflector system is thus adjustable to
secure the optimum result for the particular system.
This was one of the models selected for immediate post-war production. Has a 'Type 1 Distribution' (Non Cut-Off) according
to the draft 1945 specification; and can be adjusted to a 'Type 2 Distribution' (Semi Cut-Off) with adjustment.

london b/3 pattern lamp
Introduced in 1946. It includes improved modifications to
the top casing, and is being extensively used for modern street lighting, being primarily designed for
Group 'A' schemes. It has a special mirror glass optical system, which can be very easily and accurately
adjusted to obtain the best result according to the nature of the surface of the road. Alternatively, special
reflector systems can be supplied, these being a low cut-off system, and a back reflector to give unilateral
distribution.

High Visibility / H. V. Lamp
First exhibited and installed in prototype form at the APLE's 1937 Conference in Folkestone. Originally
called the "H. V. Lamp" which could stand for "High Visibility." The exterior of the final
model was to be considerably modified, but the redirective equipment was to be retained
unaltered. The lamp used specially designed mirror glass reflectors (Zeiss Directional
Reflector) giving a complete cut-off below the horizontal, together with an axial
beam intensity at angles of 60°-70°. The type of distribution ensured that
a much greater proportion of the total flux reached the road surface, resulting in
higher illumination for a given gas consumption. And the design of the lamp such that
its weight for a given light output had been considerably reduced making it possible
to suspend two or three lamps on a single span wire.
It was the prototype of the "Folkestone" lantern - see below.

Folkestone Lantern
First exhbitied in embryo form at the APLE's 1937 conference in Folkestone as the HV Lamp. Even though
conference literature suggested the lamp would be externally redesigned - but retaining the optical system -
the lamp appeared for sale, now called the "Folkestone" lamp, the same month. The design was perfected in 1938.
It was of the "cut-off" type and installations were characterised by an entire absence of glare and amazing visibility.
Especially suited for central suspension. Two sizes were made post-war: 4-light No. 2 mantle burners and
6-light No.2 mantle burners.
Has a 'Type 3 Distribution' (Cut-Off) according to the draft 1945 specification.

Series 8000
Designed primarily for Group B roads. The whole of the body of the lamp is cast aluminium. It is arranged as a unit with a Wrought Iron
Swanneck and Controller Base, the control equipment being housed in a lifting sheet-iron
cover. THe Lamp is fitted with curved mirror glass reflectors. A three-way version for Group "B" lighting at
junctions was introduced in 1938. Two of the swan neck options are the "B" type and "D" type.
Tests have proved that the efficiency of the "8000" Lamp referred to the total
lantern lumen output per c. ft. of gas consumed, is considerably greater than that of any other low pressure gas
unit of normal design at present available. This high burner efficiency is obtained
with silk mantles or normal impregnation. Low in maintenance costs and designed to give a long and
satisfactory service. Redesigned after the war. With various lengths of swan-necks available
('D', 'E' and 'F') then can be adapted to existing columns.
In 1946, the 8000 lamp is shown with
two distinct forms of mounting. In one case it constitutes the ideal conversion unit for bringing old gas installations
up to date at the lowest possible cost. With the new Sugg C.U. concrete bracket and column it provides a completely
modern lighting unit, suitable for new housing schemes. The clean outline of this design will appeal to all as a great
improvement in appearance. The high efficiency of the lighting unit is already well known, and some
detail improvements recently made have reduced maintenance costs still further.

highway lantern
Designed in 1939 and exhibited at the APLE's conference the same year.
The reflector system embodies paraboloid reflectors giving a distribution of light
adequately wide for all normal roads, with a polar distribution particularly
suited to the production of high road brightness but at the same time controlled to
prevent excessive glare. The reflector system has a low absoprtion giving high
total lantern lumen output. The burners carry twelve mantles in a special arrangement
of two rows, and project considerably below the flat top reflector. The anodised
aluminium specular reflector system consists of two complete reflector units and
mountings, each adjustable over a wide range horizontally and also vertically
if necessary. These units are easily removed, and the burner can then be detached
for maintenance. Designed for Group A lighting at 25', 5' overhang up to road
widths of 40'. A novel point on the lamp is that it has been found possible for the
first time to calibrate the reflector mounting in degrees laterally, thereby greatly
simplifying their adjustment. The lamp body has four doors, self-supporting
when open, for easy of maintenance. The whole top of the lantern is made
from copper, and the basket is also incorrodible.
The lantern is constructed on modern lines in the form of a heavy gauge top, rectangular
in plan, which incorporates the flue, burner and mantles; an enamelled iron top reflector supports
the directive equipment, and the non-corrosive glazed body has four access doors. The reflector
system embodies the use of paraboloid reflectors with the object of providing a distribution of
light adequately wide for all normal roads, and with a polar distribution particularly suited
to the production of high road brightness without excessive glare and giving a high lantern
lumen output. The burner is normally fitted with twelve mantles arranged in two rows, and it
projects somewhat below the flat top reflector. The anodized aluminium specular reflector units
and mountings are each adjustable over a wide range horizontally, so that the direction of
the maximum intensity can be set to the best advantage, both on straight and curved roads.
The vertical angle can also be adjusted if this is necessary. The reflector unit can be very easily
removed and the whole burner system is then detachable for maintenance, etc.
