Abstract
A marking device includes a plurality of individual marking pin assemblies. Each marking pin assembly is spaced an angular distance from each adjacent marking pin assembly in the marking device to form a generally fan-shaped array. An arcuate object to be marked by the marking device is placed on an object support plate. As the arcuate object is rotated on the object support plate, the plurality of marking pin assemblies in the marking device operate to selectively imprint a plurality of preselected characters in the circumference of the arcuate object.

Apparatus for marking on an arcuate surface comprising,
- marking means for marking the circumference of an object having an arcuate surface with a plurality of characters of preselected height, said marking means including a plurality of marking head assemblies spaced from each other by a preselected angular distance to form a generally fan-shaped array,
- said plurality of marking head assemblies angularly spaced from a circumference of said object by a preselected degree to control said height of said characters,
- mounting means for supporting said marking means,
- object support means for supporting said object having said arcuate surface, said object support means positioned to provide that a longitudinal axis of said object is substantially perpendicular to said plurality of marking head assemblies,
- positioning means for positioning said arcuate object on said object support means, and
- means to actuate said plurality of marking head assemblies to selectively imprint a plurality of marks in the circumference of said arcuate object and form said plurality of characters.
A method for marking on an arcuate surface comprising the steps of,
- providing a marking means for marking the circumference of an object having an arcuate surface with a plurality of characters of preselected height, said marking means including a plurality of marking pin assemblies spaced from each other by a preselected angular distance to form a generally fan-shaped array,
- angularly spacing said plurality of marking pin assemblies from a circumference of said object by a preselected degree to control said height of said characters,
- positioning said object having said arcuate surface on an object support means so that a longitudinal axis of said object is substantially perpendicular to said plurality of marking pin assemblies, and
- selectively moving each of said plurality of marking pin assemblies into and out of contact with a circumferential surface of said object to imprint a plurality of marks in said circumferential surface to form said plurality of characters.
