How Not to Improve THERE is a good story going Those Rates for A the rounds in the Midlands Haulage concerning a deputation of
hauliers who waited upon a brick manufacturer. He, adopting tactics so very familiar to hauliers, had told haulage contractors working for him that he proposed to reduce a rate of 10s. per 1,000 by a shilling. These hauliers had agreed together that 10s. was a minimum. They discussed the price with the brickmaker and parted as the Navy saying is, "brass rags," neither side giving way. The hauliers proceeded to their separate homes and each of them promptly sat down and wrote a letter to the brickmaker offering to do the work for 9s. !
(.18 JUST as regular cleaning and greasing may bring to notice loose nuts, etc., before trouble results, so may efforts to locate an elusive rattle lead to a general improvement in maintenance. An owner-driver haulier of our acquaintance, who is also his own maintenance engineer, in seeking the cause of a mysterious noise, has soundly repaired a disintegrating battery box, securely fixed a loose silencer, replaced a broken spring leaf, fitted eight new shackle pins and had a
slack spring-bracket rivet tightened up. The last time we saw him the source of the noise was still eluding him, .although he had discovered one additional trouble—a defective petrol pump.
The Elusive Noise May Be a Mixed ,Curse
Substantial Progress Expected with the Rubber Wing . . .
ONE has not heard much of the rubber mudguard for motor vehicles, but if the optimism of the Dunlop Rubber Co., Ltd., is justified one can reasonably expect distinct progress to be made in its use, particularly for buses and coaches. The company commenced practical developments with this equipment in 1932, and over 2,500 vehicles are now fitted with rubber wings which, apart from reducing maintenance charges, will, it is believed, contribute to safety.
The Importance of usA FEATURE of the Bristol ing Oil which Flows 1–k engines installed in the Freely When Cold . giant flying boats now going
into service on the Empire routes is that an automatic valve admits extra oil to the bearings when starting from cold. Thus preliminary warming up is unnecessary. A similar arrangement would be valuable on commercial vehicles. In its absence the use of a good-quality lubricant which flows freely at low temperatures is advisable. The engine can then be run at heavy load from the start, and quickly warmed up, thus minimizing cylinder-bore wear and reducing the time lost.
Unreliability of EyeTHE value of the evidence of
witness' Estimates of 1 witnesses in cases where the
Speed speed of a motor vehicle is in dispute is often open to question, and tests recently carried out in Sweden prove that eye-witness' accounts are seldom reliable. Some 21,000 tests were carried out under all sorts of conditions, both by day and night, with persons of all classes, including experts, but not more than 18 per cent, of them were able to get within 5 per cent, of the actual speed of a vehicle, whilst over 50 per cent. were 20 per cent. or more out in their estimates. The experts made no better showing than the laymen.
