The Bi-Multi system incorporates scientifically designed units to deal with every individual position, and in addition a series of graded reflecting surfaces planned to give varying multiplication ratios. A great feature is that the Bi-Multi Reflector provides for efficient utilisation of the light flux, with low maintenance costs.

bi-multi group "al" four way
Patent: 228294
Registered: 736776
Suitable for side streets and rural main roads of moderate traffic density. The four-way reflector was designed for cross roads. Superseded the Group A reflector as it didn't comply with the Final MOT Report which was published in 1937. Had a wider angle beam at lower peak candle power which complied with the Final MOT Report's guidance on glare. Single piece casting with silvered glass facets cut from a flat sheet, embedded in a special atmosphere resisting cement. Made from cast iron (11lbs) or aluminium alloy (5lbs). Color in green or aluminium - other colours were available to order. Anti-vibration bayonet cap or Edison screw as standard - rigid version an option. Approximate dimensions are 12" (length), 11¼" (width) and 10½" (height). Peak candle power porjected at 10° below the horizontal. Recommended average economical spacing of posts is ten times the mounting height. Clear gas filled single coil tungsten filament lamps should be used. Type of glass can be changed to semi-dffusing silvered glass if installed at lower mounting heights. A wide number of angular settings are available to suit any road scheme. special patterns can be made on request. The angles are read in a clockwide direction looking down on the fitting.

A special patented method of light control is employed, by which the elongated light source is split into two imaginary sections, each reflector redirecting the light flux from the respective sections. Mounting height should be 25' or over.

bi-multi group "b/al" three way
Patent: 228294 and 426069
"Introduced in 1937, these feature the patented double-tier design which sectionalises the long light source."

The reflectors consist of one piece castings glazed with silvered glass facets, cut from flat sheet, embedded in a special atmospheric resisting cement. Available in cast iron (44lbs) or aluminium non-corrosive alloy (25lbs). Finished in green or aluminium (other colours available). Bayonet cap lamp holder. Approximate dimensions are 17" (length), 16" (width) and 23" (depth). The peak candle power is projected at an angle of 12½° below the horizontal. A special patented method of light control is employed, by which the elongated light source is split into two imaginary sections, each reflector redirecting the light flux from the respective sections. Mounting height should be 25' or over. An interesting modification may be adopted in the case of three way and four way road intersections by which the light flux may be directed on to the various roads in direct proportion to their traffic density and importance. This flexibility is effected by combining a three way upper reflector with a two way lower, or a four way upper with a three or two way lower.

The reflectors consist of one piece castings glazed with silvered glass facets, cut from flat sheet, embedded in a special atmospheric resisting cement. Available in cast iron (22lbs) or aluminium non-corrosive alloy (10lbs). Finished in green or aluminium (other colours available). Bayonet cap lamp holder. Approximate dimensions are 12" (length), 11" (width) and 14" (depth). The peak candle power is projected at an angle of 10° below the horizontal. It employs a special patented method of light control by which the elongated light source is split into two imaginary sections, each reflector redirecting the light flux from the respective sections. Not to be erected at a height of less than 17'. The reflector is available in the various angles as for the Group "AL" lantern.

Patent: 228294 and 426069
The reflectors consist of one piece castings glazed with silvered glass facets, cut from flat sheet, embedded in a special atmospheric resisting cement. Available in cast iron (22lbs) or aluminium non-corrosive alloy (10lbs). Finished in green or aluminium (other colours available). Bayonet cap lamp holder. Approximate dimensions are 12" (length), 11" (width) and 14" (depth). The peak candle power is projected at an angle of 10° below the horizontal. It employs a special patented method of light control by which the elongated light source is split into two imaginary sections, each reflector redirecting the light flux from the respective sections. Not to be erected at a height of less than 17'. The reflector is available in the various angles as for the Group "AL" lantern. In addition, a very interesting modification may be adpoted in the case of three way and four way road intersections by which the light flux may be directed on to the various roads in approximate proportion to their traffic denisty and importance. This fexibility is effected by combining a three way upper reflector with a two way lower, or a four way upper with a three or two way lower. Therefore this vertical arrangement is suggested for use at junctions.

bi-multi group "al/1 hs" two way
Patent: 228294 and 426069
"Introduceed in 1937, the optical design "sectionalises" the long light source with the result that the excessively wide lateral light distribution is restricted to more practical limits."

The reflectors consist of one piece castings glazed with silvered glass facets, cut from flat sheet, embedded in a special atmospheric resisting cement. Available in cast iron (14lbs) or aluminium non-corrosive alloy (6lbs). Finished in green or aluminium (other colours available). Bayonet cap lamp holder. Approximate dimensions are 12" (length), 13" (width) and 7" (depth). The peak candle power is projected at an angle of 10° below the horizontal. This lantern produces a light distribution suitable for normal and close spacings and wide roads. The maximum candle power intensity is not so high as with the double reflector but the width of the light spread is more adaptable to the conditions mentioned. To be mounted at 17' or more. This reflector is mainly for the economical application of sodium lamps to the usual two way lighting.

"Introduceed in 1937, the optical design "sectionalises" the long light source with the result that the excessively wide lateral light distribution is restricted to more practical limits."

The reflectors consist of one piece castings glazed with silvered glass facets, cut from flat sheet, embedded in a special atmospheric resisting cement. Available in cast iron (26lbs) or aluminium non-corrosive alloy (13lbs). Finished in green or aluminium (other colours available). Bayonet cap lamp holder. Approximate dimensions are 21" (length), 13" (width) and 8" (depth). The peak candle power is projected at an angle of 10° below the horizontal. The speical method of light control, namely sectionalisation of the light source, enables the light flux to be redirected on to the thoroughfare with close precision, thus obviating undue waste of light on to the boundaries of the road and in upward directions. This design also permits of the light flux being projected at other angles than 180° in plan. That is, fittings can be supplied to produce the correct distribution for staggered and one side lighting in addition to central suspension systems. Moderate bends and certain three way junctions can be catered for. To be mounted at 20' or over.
