Gas Light And Coke

The Gas Light And Coke Company
84 Horesferry Road

Was the largest gas undertaking in the UK. - Public Lighting #3, 1936.

Sir Francis Goodenough was the manager of the sales department. "He took a census of the company's district to gauge its possibilities, trained a special body of salesmen, engaged women experts in domestic science to demonstrate the use of gas appliances, and advertised the company's service in the newspapers. In consquence, many other gas undertakings and gas appliance makers benefited from the company's advertising. Some actually offered to bear part of the cost. This suggested the idea that a national scheme of advertising might be floated, with contributions from gas undertakings and makers of appliances all over the country. In the discussion which followed, it became clear that there was need for a strong central body to co-ordinate other activities besides direct advertising. The result was the formation of the British Commercial Gas Association" - Public Lighting #3, 1936.

Founded in 1812. By 1937, was responsible for the lighting of over 60 miles of streets in London. - Public Lighting #7, 1937.

Modified a photo electric cell for lighting street lamps between dusk and dawn. A recitified photo-electric caell is fixed in a suitable position on the lamp and is connected with the main control box. The components in the box include an electric relay, a 3-volt dry cell and a clockwork operated gas valve which incorportes a switching device. When daylight falls below a pre-determined value, the current from the photo-electric cell operates the relay, which allows a small current to flow from the dry-cell to energise an electro-magnet, which operates the trip mechanism on the clockwork gas valve, which then turns to the "on" position and lights the lamps. A similar operation occurs when the value of daylight increases to a pre-fixed value and the lamp is extingushed.

It can be used for refuge islands with centre lamp; and for all lamps and signs on a roundabout. It is possible with Comet ignition to light all lamps up simultaneously. The only attention required is the winding of the clockwork mechanism - about once every three weeks - and the renewal of the battery - not more than once per year. The control was patented by Mr. W. H. B. Hall, Mr. R. H. Whillock and the South Metropolitan Gas Company originally for use in schools. It was developed by Sugg for street lighting in conjunction with the Public Lighting Section of The Gas Light & Coke Company - Public Lighting #11, 1938

Designed an automatic cut-off valve for illuminated guide posts and road signs in the late 1930s. This was fitted to all their guard posts in their area. The device was manufactured by Sugg. - Public Lighting By Gas In Small Towns, 1938.

The possibility of an escape of gas igniting if a gas-illuminated bollard is knocked over was looked at by the Public Lighting Section of the The Gas Light & Coke Company. They devised an automatic cut-off valve which is being manufacturered by Sugg. The valve is fixed to the service in the base of the bollard, preferably below ground level, and the supply to the burner is conencted to it by means of an easily broken nipple, which ensures the valve not being broken away from the service if the bollard is knocked down. The device itself is diaphragm operated, the inlet gas passing to the underside of the diaphragm and thence through a valve to the burner. The effective area of the valve is small in relation to that of the diaphragm. Pressure at the burner is conveyed to the upper side of the diaphragm by a small bore tube, and under ordinary conditions, with almost equal pressure both above and below, the valve is kept open by its own weight. Immediate fracture of either the main supply or the small bore tube, the pressure above the diaphragm is reduced to atmospheric, and the inlet pressure snaps the valve shut and keeps it in this position until pressure is again applied above the diaphragm by means of reconnection. Owning to the success of this device, it is now being fitted to all gas lighted bollards and guardposts. - Public Lighting #11, 1938
