Tarpaulins, Canvas Sheets and Covers for Lorries, Motoreab and Van Tops.
The essential equipment to be carried with every open-top industrial vehicle should, if used for the delivery of goods of a more or less delicate texture, of course, be a good, strong, waterproof cover, especially for long-distance carriers, where the loads are likely to be exposed to rain or dust. We call our readers' attention to the firm of Messrs. Mayor and Son, 6, Wharf Street, Preston, which has been established for over half a century, and which specializes in all classes of tarpaulin and canvas covers for motorcabs and van tops, chemical-proof sheets and oil cloths of all descriptions.
Owners of open-top lorries, general carriers, cotton manufacturers, and tradesmen anticipating either renewing or purchasing covers for their machines in readiness for the coming winter will do well to get in touch with this firm. The company also stocks many classes of lubricants for engines.
Robbialac Enamel Compound, and a Non-inflammable Paint Remover.
There can be, we feel sure, no better investment on the part of owners of chars-à-banes and industrial vehicles of all classes, than periodically, between seasons, to have the bodies and general framework of their machines repainted with a good, hard-drying and wear-resisting paint or enamel. Besides greatly tending to lower the percentage of depreciation, the consequent clean and smart appearance given to the trovelling equipment undoubtedly proves of good advertising value.
We have had brought to our notice what appears to be a very satisfactory medium in this respect in the form of Robbialac permanent enamel paint. It is marketed by Jenson and Nicholson, Ltd., Goswell Works, Stratford, London, E., and the maker claims that. its wear-resisting qualities warrant it. as particularly suitable for commercial-vehicle bodywork.
It is manufactured in concentrated form and provides a finishing coat, which, we understand, is far in advance of the older method of using both paint and varnish. It dries with a brilliant surface and acts as an ideal protective agent for wood, metal or composition. Robbialac is made in various shades.
The other particular production manufactured by this same concern to whieh we would call our readers' attention is the " N.S." paint remover. We are ininformed that this composition is the result of careful investigation and experimenting on th.e part of the makers to produce an infallible medium for re moving varnish, paint or polish without injuring the surface of the article treated. The liquid is ready for immediate use, and an important feature is that it is absolutely non-inflamtnable. No brush is too old or too hard to be recovered from congealed paint while the bristles last if this paint remover be employed. There is no caustic soda or other alkali used in its -manufacture The Comminuter Vaporizing Set.
It is, of course, a well understood fact that heat is a most important factor to be considered in the matter of vaporization of heavy fuels. When either manufacturers or users carry out modifications to their machines in order to run them on the heavier distillates as well as petrol, any alteration to standard practice generally commences with the jacketing of the carburetter either with water taken from the main circulation, or by utilizing the exhaust gases for the purpose of vaporization.
Quite an advance step, however, has been made in this direction by a manufacturing concern, which has brought out a system by which the heat necessary for vaporizing heavy fuels is actually drawn from the combustion chamber at the instant of explosion, when the gases are, of course, hottest.. The concern in question is the M.G. 6E G. Motor Syndicate, Ltd., Clarence Chambers, Kingston-on-Thames, and the patented device is marketed as the " Comminuter."
The accompanying illustration shows a part arrangement of the system as applied to a four-cylinder engine, the small figure being a view of the three-way supply valve which is connected up to the vaporizers, the main fuel-tank and the subsidiary petrol tank. The screwed cap enables the supply of fuel to be regulated to suit. various conditions of running. The vaporizing chambers themselves, one for each cylinder, are fitted into position by merely taking out the sparking plugs and screwing suitable carriers, which are provided, in their place ; a plug is then screwed into a boss on each vaporizing chamber.
Flexible steel tubing can be used to connect up any standard make of carburetter to the vaporizers ; the hot gases in the circuit may be regulated as desired to suit various grades of fuel. The makers state that, by this particular system, as much as. 1000 degrees Fa,hr. can be withdrawn from the combustion chamber, which enables engines, hitherto designed to be run on petrol, to use benzole, paraffin, alcohol, naphtha, solar oil, gas oil, besides. many residual oils.
All parts necessary for a complete installation are supplied with each Comminuter.
