DRASTIC TYRE TESTING MACHINE.
Bagineering, reading the effects of constant wear on tyre reads at the U.S. Bureau of Standarda laboratory.
Washington, July 15. While Thomas Edison is experi- mentally developing rubber plan- tations in Florida, the U. S. Bureau of Standards here is de- liberately destroying rubber com- pounds.
This is not a rash undertaking, however, but a purposeful inves- tigation into the relative ability of matorinis entering into the making of automobile tyre treads to offer resistance to abrasion or the tendency to rub away when in
action.
To the approximately 26,000,000 owner of automobiles and motor trucks in this country, these tests will ultimately mean longer life for tyres and a saving in dollars and cents.
tion continues until the test speci- mens are worn down one-tenth of an inch.
Resistance to this rubbing-away tendency is indicated by loss in thickness of the samples and the thinning process is registered on gauges.
This is one of a series of tests
at the Bureau of Standards to determine the wearing quality and lengths of life of automobile tyres, Durability of tyres and their power loss or energy dissipated by heat, when operating under vary ing conditions of axle load, speed and inflation pressure, are being studied.
