a wooden base. Each of these electro-magnets bears at one end a mass of 

 soft iron, -while from the other projects a metal point, which by means of 

 a small band moves a long lever of the third order, and this last moves by 

 means of another very long band an eccentric, situated on the axis of 

 revolution. OH this same axis there is also a commutator which serves 

 to send a current of electricity alternately into one and the other of the 

 electro-magnets. This motor, on equal conditions, has a force superior to 

 that of many other electro-magnetic motors.
