A l k izing this half-speed shaft a plain single caln may be employed. ltwill be noted that the rod which opens the valve, which latter may be the inlet-valve of the engine, is nioviiig in the proper direction to permit said valve to close when it breaks the sparking circuit, and the special recess in the cam assures that this circuit shall not be broken until after the said 'alve shall have closed Having thus described nrv invention, What 1 claim, and desire to secure by Letters Patent, is-

1. An internal-eoinbustion engine, having a valve to be opened, a rod, slidable in guides, for opening the said valve, the guides for the rod, a can! for operating said rod to open the valve, said cam having in its operative edge a special recess, av spring whiehholds said rod in operative relation with the cam, a laterally )rojecting part on the said slidable rod, :1. tixed electric contact, a movable elect ic con tact, a spring which holds said conta t: normall in touch with each other, a movable contact-actuating arn'i in the path of said lateral projection on the rod and adapted to be actuated thereby When the spring on the rod moves the end of the latter into the recess in the cam to produce a spark between the ,contacts when said I1".0V&bl8 arm is actuated.

2. An internal-combustion engine, having a valve to be opened, a rod A for opening said valve, a cam B for operating said rod to.

open the valve, said cain having a recess 5, a s )ring 0 which holds said rod pressed up to the earn, a projecting part (1 on said rod, a rocking spindlef, in the Wall of the combustion-chamber, an arm e on said spindle in the path of the part (1, a fixed contact is, a contact-arm g on the spindle f, and a spring h which keeps the contacts normally in touch substantially as and for the purpose set forth. In Witness whereof I have hereunto signed my name, this 24th, day of February, 1904, in the presence of two subscribing Witnesses.
