Abstract

129,557. Wright, I. H., and Smith & Coventry. Dec. 18, 1918. Drilling-machines.-In drilling-machines in which ball bearings are provided for the spindle, the upper ball thrust bearing a is arranged between a collar b fast on the spindle and a collar d attached to a sleeve d<1> which can slide in the main sleeve e. The collar d is connected to the counterweight g, so that the sleeve d<1> adjusts itself to take up slack in the bearings.
