Student with the later single-lever "Safety Apron" and "Third-shaft" electrical control
Another (rarely-encountered drive configuration) drive used a two-speed Brook Compton motor and an electrically-actuated disc brake. On this model the normal "plug-in" electrical control panel on the front of the stand was replaced by a line of four switches and a stop button immediately beneath the front edge of the chip tray. This version also had a "third-shaft" control rod fitted below the powershaft and operated by a lever attached to the right-hand end of the apron - an arrangement not unlike that employed on a Mk. 1 Bantam. At the right-hand end of the rod was a box, containing a cam that operated the special Klockner Moeller reversing switchgear. On some of the Klockner-equipped lathes an unusual (and presumably heavier-duty) main spindle arrangement has been found where, instead of the components being located by a single key a much heavier fully splined shaft was used with the sliding components engaged by dog clutches. If you have one of these models the writer would be interested to hear about it.
