Silent-chain drive. A popular fitting from the 1920s and 1930s. The chain was automatically lubricated. Although giving a slip-free drive it was relatively harsh and, of course, unforgiving in the event of a dig-in other accident.

Table and saddle ways - and the table feed-screw end bearings - were lubricated by a one-shot pressure system, driven by an operator-actuated pump, mounted on the front left of the saddle on horizontal millers and to the right on vertical.
