Cams are mechanisms that can help to generate movement in mechanical toys. Cams normally work with a cam follower, which is normally a rod made of wood or metal, supported by a shaft that limits the movements and direction of the toy.
Basic principle of cam: To turn in a circular motion in to one that move up and down, which is called reciprocating movement.In this gravity hammer, the bumps on the turning cam push the end of the lever down and raising the hammer continuously.
