' Application filed 11m h 22, 1917. Serial no. man.

residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements 1n Simft-0pcratingiMechanism; and I- hereby declare the followin to be a full, clear, and exact description 0 the invention, such as will enable others skilled in the art to which it pertains'to make and use the same.

This invention relates to improvements .in mechanism for. actuating" rock-shafts, and pertains more especially toimproved shaftoperating mechanism comprising a footlever operatively connected with an arm of arm in one direction against the action of a spring, a hand-lever arranged near the foot-lever and operatively connected with an arm of another shaft for efie'cting the actuation of said arm in. one direct-ion against the action of aspring and inde pendently' .of the first-mentioned shaft,

means normally locking said hand lever against movement in the o posite direction, and means independent 0 said hand-lever" for efl'ecting the aforesaid actuation of the second'mentioned arm simultaneously with and during the aforesaid actuation of the firstqnentioned arm by the foot-lever.

One object of this inventionis to provide such a connection between the hand-lever and the arm ofthe second mentioned shaft that during the actuation of said arm by the hereinbefore' mentioned means employed actuating said arm independently of the i so - and relativejarran'geme'nt of parts herein:

hand-lever, said hand-lever remains undisturbed andmovement of'said arm is therefore'not accompanied by movement of the hand lever. v

Another objectis to have the means employed, independentl of the hand-lever, m

actuating the arm 0' the second-mentioned shaftsimultaneously with and duri the actuation of the arm of the firsbment oned shaft ;by the foot-lever, not only simgl'e in. utto have Saldiilfiflllfl convenien y adjustable and construction and lqfidily a. plicable,

readily accessible for repairs; renewal, cleaning and lubrication. Y

With'these objects in view and to the end of attaining any;otherobjectlhe'reinafter substantially parallelwith the Shaft B. The

appearing, this invention consists incrtain features of construct1on,-and combinations s ms... airmen m PatentedJuly 24, 1917.
