LESSEN LOSSES BY FRICTION

Two Methods, One American and One English, That Are Expected to . Accomplish Much. Two methods recently developed to overcome the retarding effect of journal friction are shown In these illustrations, one being an English method, and the other American. In the latter, a. series of short rollers of relatively large diameter take the place

of the ordinary ball bearings. These rollers are adapted to tbe existing type of truck without much difficulty. It Is claimed that the results show a

saving in power of over 25 per cent, and a saving of at least two-thirds in lubricating oil. The Einglish device consists of an

anti-friction roller or wheel, mounted as shown. It is claimed that at least 60 per cent of the friction developed in the axle-box is done away with, the anU-frtctlon wheels being mounted in separate journals over the ends of the axles. One great English railroad has equipped over 1,000 of Its cars with this device. In actual service the wheels are covered with thin metai shields to keep out the dust.— Popular Mechanics.
