Arcturus
Registered Design: No. 794896
Patent: No. 296888
For Group A and B lighting. Describes as the Circular Suspension or "U" Bracket Lamp. (If fitted to a "U" bracket then called the
"Supported Arcturus Lamp.") Could carry a cluster of burners (both 1, 6 and 15 are mentioned)
and could be fitted with optional directional fittings such as back-reflectors (183, Pat No. 797495) and optional Holophane
dish refractor (2/4403). Adverts show the plain fitting described as giving "an even distribution of light."
Available in the "usual" sizes for Group "A and "B" roads. The casting is exceptionally windproof with
an interesting design that the primary and secondary air supplies to the superheater burner are entirely
separate. At least five sizes of lantern were produced. The "Registered Back" or "Globe" reflectors are manufactured from
"Staybrite" steel.
The Arcturus circular suspension lamp, is available from 1 light or 15 light cluster, and has been
appreciated for its robust construction and consequent long life. It has been widely adopted for long-term
contracts where maintenance costs are required to be kept to a minimum. The superheater burner has separate
primary and secondary air supplies and there are cleaning plugs to the gasways; the enamelled steel shade can
carry the "Registered Back" reflector (reg. des. 797495 of 27/10/34) in "Staybrite" steel and the "Isolight"
under-mantle reflectors, while the "Globe" under-mantle reflector is available for fitting inside the globe of the
5, 6 and 7-light sizes; Holophane refractors may be used with these lamps. The lanterns have easy access
and dual-feed burners are available for reduction of light by controller at pre-determined times. All makes of
clock controllers are supplied and Newbridge "Comet" ignition fitted to order.

alpha
Patent: No. 23393 & 23394
For Group A lighting. Described as "the rectangular suspension lamp". Considered the 'leader' of the range. Designed for
Group "A" roads. This lamp is the "Avil" contribution to uniform street lighting having a twelve-light alignment burner
needing only one byepass and equipped with mirror glass reflectors; the mantles are accessible without removal of
any internal parts and the lamp gives a solid rectangle of light without glare. The reflectors
lift out for cleaning, but are non-adjustable and therefore the lantern is described as "ever
focussed." There are at least two different sizes: one for six burners and one for twelve.
Awarded provisional patents 23393 and 23394 in late 1936. Registered design 814858. The Alpha rectangular
suspension lamp, available with 6, 8, 10 or 12-light burners, is another unit
of proved success and popularity.
The shape and general appearance of the lantern conforms with present-day practice. It is made
in four sizes, having respecitvely six, eight, ten or twelve mantles, and the distribution
has a wide horizontal spread. The lantern was developed from the well-known Avil
"Strip" lantern. An intensive beam candle power is deliberately avoided by using flat glass
reflectors which are specially treated by a process ensuring full resistance to conditions
met with in use. These mirrors are situated above and below the line of mantles, there being
no obstruction of any kind in front of the light source. Positioning of the mirrors is
obtained by their being fitted into cast frames of light alloy which lift right out of the lamp
for maintenance purposes. The setting of the mirrors according to the spacing of the units
and other conditions under which the lamp is to be fitted is usually determined during manufacture.
For side lighting the lamp is usually supplied with "Staybrite" steel reflectors attached to the inside
of the mirror end frames to increase the beam spread across the road. The body, canopy and ventilator
of the lantern are constructed from copper, and both end frames of the lantern are of cast brass.
The end frames, together with a bridge piece, give the lamp complete rigidity, and the all-copper
casing ensures a long useful life.
By 1947, the lantern had been 'somewhat' modified from pre-war experience. The reflectors, which can be lifted
from the lamp as a whole for cleaning, provide not only light for the main beam, but also light at a lower angle to
prevent the throwing of shadows by the case. The reflector sysmte had beem imporved and had
mirrors of glass or Staybrite steel. Horstmann type 15/3A/COM controller, constant
pressure governor and safety chains are supplied.

sideway
The Avil Sideway lamp has been recently introducd for Group B
roads under the recommendations of the MOT's Final Report. Supplied in sizes from
one mantle to four mantles, the lamp is claimed to be the best illumination yet
offered for such sizes. The "Sideway" is a globe unit for axial or non-axial lighting,
fitted as standard with mirror glass reflectors above the light source and with provision
for a Staybright steel faceted back reflector or Holophane
dish reflector. The lamp is easily accessible for cleaning, the globe of standard
size to facilitate maintenance, and for pillar fixing the bracket carrying the
lamp is in effect an extension piece available with or without ladder bars.
Newbridge "Comet"
ignition may be incorporated in this unit and to meet local conditions an
ordinary by-pass cock operation is available. The lamp is available also for
bracket fixing. For pillar fixing the standard length of bracket gives a height
to light source of 4' above the spigot; the bracket dimension can be varied to requirements.
Designed for Group "B" roads (but could be used for Group A).
Described as the unit for kerb line lighting, which gives light to the road as well.
A complete unit with controller base and bracket. It distributes two beams of light at 180°
from each other along the kerb edge without producing glare. At the same time that portion of
the light which would normally be thrown on to the houses at the back of the footwalk is distrubuted
onto the roadway by means of reflector devices. It is usually supplied with a clock controller and
a constant pressure governor housed in the base of the supporting arm of the lamp. Lamp is fitted
with a bypass of the usual type and a level cock may be fitted. Casting is of light rustless metal and
the superheated cluster of mantles is surrounded by a pear-shaped super heat resisting glass globe.
Consists of two reflectors at right angles to the kerb and projecting almost horizontally
from the body cating above the globe support, light from the lower hemisphere being collected and redirected
by means of a glass refractor carried underneath the mantles and inside the globe. Light from the
house side is dealt with by a special small reflector attached to the arm. All reflectors are
capable of adjustment to suit bends in the road or hills.
The 1944 is fixed on an "A" Type bracket with ladder bars, having the No. 170 mirror reflector above
the mantles, and Holophane Dish Refractor, No. 22/4400, in the globe, fitted with Newbridge 3A/UNI controller
and Mark VII "Comet" igniter. The lamp has a globe of the normal type, size and fitting. The Type A Bracket
provides accommodation in the base for controller, "Comet" igniter and governor and is normally 48" long.
The 1974 on "E" Type Bracket is suitable for new installations, and has a No. 170 mirror reflector and
No. 175 back reflector in Firth's "Staybrite" Steel with Newbridge controller 15/3A/COM incorporating
"Comet" ignition. Can be supplied with or without ladder bars and for bracket fixing to poles or walls.
Three other types of upright brackets are available for use with the "Sideway" lamp..
Was redesigned and relaunched in 1947. (See 'New' Sideway below).

new sideway
Introduced in 1947. For Group B lighting. The new Sideway lamp is designed to give better lighting at the same cost, or equally good lighting
for less cost, than has been possible with earlier models. The lamp is of relatively small dimensions and the novel refelctor
scheme is designed to give a greatly increased candle-power at angles between 70° and 80° from the downward vertical.
This is acheived withotu the glaring effect often associated with reflectors, for the candle-power at 90° is only about
half that which would be obtained from the bare mantles. However, this semi-cut-off design does not give the sombre effect
often associated with it in the past, since there are wide gaps in the reflectors which permit light to pass ot both the
building frontages.
The reflectors are so made as to be easily cleaned and screened from falling rain. The lamp incorporates a burner with
self-extinguishing injector, a result of which great stability is achieved and lighting-back made impossible. The body is
aluminium and is of an entirely new design, which combines lightness with ease of maintenance.
Mounted at 15-ft. from the pavement at spacings of 120-ft. as recommended in the M.O.T. Report, these lamps will give excellent
street lighting. Even at greater spacings up to 200-ft. adequate illumination will be provided on the footway. It is worth mentioning
that even when very widely spaced these lamps are not glaring and for that reason can safely be used on otherwise unlighted
traffic routes.
Designed to house two, three or four No. 2 mantles. Reflectors are of Staybrite steel and are
screened from the falling rain. The controller is a Horstmann type 15/3A/COM.
