September 27, 1918. THE COLLIERY GUARDIAN. 643 IS FERODO FABRIC FACTS i Invented 20 years ago, Ferodo Fabrics are to-day as superior to other friction surfaces as they were in those days to the “ makeshifts ” they displaced. Ferodo fabric absorbs more lbs. of energy per sq. in. than any other brake or clutch lining. It permits of maximum acceleration and deceleration. It gives rapid dissipation of heat. It is three times more durable than chilled iron— five times more durable than leather. It cannot carbonise, cannot slip nor seize, cannot spark, cannot throw off metal dust. It gives equally effective service when first fitted and when worn to the thickness of a piece of paper. List Ferodo fabric has been exclusively used for many years by the London and Paris Underground Railways. It stops the London Underground trains, travelling at thirty miles an hour, in five seconds without jerk or noise. On the London Omnibuses the average life of the Ferodo brake lining is 50,000 miles. It is used on cranes and winches, winders and haulages, hoists and friction drives, clutches for every purpose, on every duty where an efficient friction surface is essential. It is thoroughly tested in our laboratories before sending out. It is stamped with the name “Ferodo fabric ” to guard against substitution. All imitations have been proved by independent tests to be inferior. Insist on genuine Ferodo fabric for brake and clutch linings. 77. from THE HERBERT FROOD COMPANY LTD. Works - CHAPEL-EN-LE-FRITH.
