This invention relates to driving mechanism for machine tools such as boring mills, lathes and special machinery and refers more particularly to means for operating and controlling such driving mechanism. It is the purpose of the invention to provide a simple efficient and durable device for operating clutches to change from one speed to another and likewise to quickly operate a brake to stop the movement of the machine; to provide means whereby the brake mechanism can not be applied while any of the several clutch mechanism are in engagement and likewise to insure the release of the brake in advance of the operation of the clutch, and further to provide a device by means of which it may readily be determined, which of the several clutches are engaged, and finally to provide a secondary clutch mechanism whereby the several speeds of the first named speed clutch mechanism may be further subdivided to multiply the number of speeds obtainable and also to provide connection for operating said second series of clutches.
