Century Dictionary and Cyclopedia
- n. A wheel formed so as to move eccentrically and produce a reciprocating rectilinear and interrupted motion in some other part of the machinery connected with it. See cam, 3.
“To each cam-wheel there corresponds one punch, and the eighty punches are arranged side by side and parallel upon a shaft, B, a spring, _b_, holding them constantly against the circumference of the cam-wheels.”
“The punching having been executed, and the drum, A, continuing to revolve, the punches rise a little owing to the conformation of the cam-wheel, and through the action of the springs, _b_, and allow the moistener to move forward to dampen the little circles which remain at the orifice of the punches.”
