Abstract:
An orbital marking pencil comprising:a body assembly including a plunger, a main spring and a support spring, wherein a convoluted race is formed on an inner surface of the body assembly; a rotator assembly including a rotator spring and at least two ball bearings, wherein the rotator spring opens a collet that retains a piece of lead, the ball bearings are received in the convoluted race, and the depression of the body assembly in a vertical movement actuates the ball bearings within the convoluted race, thereby rotating the lead in an orbital movement; and a rotational support, wherein the support spring provides resistance to return the rotational support to a starting position, the main spring provides resistance for and returns the rotator assembly to a starting position, and the rotator spring provides resistance for and returns the plunger to a starting position.
