The Lighting of the Vehicle.
Owners are at the present time quite naturally turning their attention to the lighting of their machines. Those who have not yet. decided upon what .particular form of lighting equipment to adopt are specially recommended to get. into touch with R. Terrell and Co., 9, Re-gent Street, London, S.W., as this concern is specializing in acetylene lighting outfits solely tor commercial vehicles.
The principal feature kept in view by the manufacturers was to bring out a lighting set having as few parts as possible in its construction, and also of a substantial nature, in consideration of the undoubtedlysevere nature of the work to which the installations would be subjected when fitted to conlmercial vehicles. Consequently, a very satisfactory form of acetylene lighting set has been marketed, and, moreover, has been adopted by many of the leading concerns owning a large number of machines, no fewer than 750 lamps and generators manufactured by this company having been supplied to the London General Omnibus Co., Ltd. Many other leading users throughout, the country have also fitted this make.
The projector itself is worthy of special mention in that the body is of cast aluminium, no sweated joints, rivets or solder being used in its construction. Thus it will be seen that these accessories are not affected by the vibration set up by the 'machine on which they are mounted. Each projector is fitted with a genuine Mangin lens mirror. One of our illustrations shows two E.C.L. cast-aluminium projectors fitted to a B-type bus.
The generator itself, which has been evolved only after long experimenting by the manufacturers, is quite automatic in action, and it is claimed that a, greater percentage of gas is obtained from the carbide than in any other generator on the. market., the reason being that a comparatively dry gas is generated by using a minimum amount of water ; moreover, the burners are not liable to get choked up. The generating portion of the equipment itself can be quickly detached, cleaned and charged. The principle upon which the E.C.L. carbide cell works is that the water pressure acts upon a small mushroom valve located in the base of the generator, allowing a small quantity to leak through a patented form of wick to get into contact with the carbide. As the pressure of gas inside the generator rises in excess of that. set up by the water the mushroom valve is closed, cutting off the supply until the gas pressure is low enough to allow the water inlet valve to reopen. Thus it will be realized that the device is absolutely automatic in its action, and a minimum amount of water is used during its working.
Two sizes of the E.C.L. generator are made. No. 1, which is suitable for omnibuses, chars-a-bancs, mailvans, etc., the capacity of the cell being sufficient to hold 4-i lb. of ordinary carbide, which will make 20 cubic ft. of gas, and will maintain seven omnibus lights for eight hours. No. 2 size is particularly suited to commercial vehicles of every description, two pro je,ctors and a tail light being used. The cell holds 21lb. of carbide, which will generate 10 cubic ft.. of gas, and will maintain three lights for eight hours. These manufacturers market many different types of acetylene bead, tail, dashboard and roof lamps, and, if required, supply. name-plates for the lamps.
Repairs to Petrol and Steam-driven Vehicles.
A timely overhaul to a machine will not only raise its working value, but will also be a. safeguand. against an awkward delay, possibly at a time when the services of the machine are urgently required.
Owners of industrial vehicles who are situated in or near either address and contemplate having their machines overhauled, repaired or modified in some direction or another will do well to get into toneh with Messrs: Gurney and Ewer, Mill Works, Ruislip, and High Street, Pinner, N. This firm is; in a position to undertake work in connection with either petrol or steam-driven machines, and both day and night shifts of workmen are iivailable For repairs of an urgent nature.
Messrs. Gurney and F.Wer have plant to enable them to carry out all kinds of machine work, such as thrning, 'cylinder boring and grinding, gear-cutting and planning. They also undertake the lengthening of chassis, repairs to radiators, petrol tanks and lubricators.
A Large stock of phosphor bronze, anti-friction metals, and steel bar, is kept at both establishments. E3
