In applying the Butler friction elements to the Miner sprin-.^gear, no material need be thrown away, as that which is re-moved is still good for repairs. The friction element introducedis not an experiment, as it is now in use in thousands of cars,and the slight change in the Miner makes an improvement tothe gears now in service, wdiich is of great value and at the sametime is comparatively A static test of this combined gear gives a splendid card, the 60,000 0. i5tatic/Ie*st^ •.

This fact makes the early spring movement a valuablefeature in the gear, as well as taking up the very large amountof slight shocks incident to shifting and starting movements.
