A marking device with a reciprocating needle is disclosed. The needle is
attached to a drive mechanism that is linearly reciprocated via a drive
motor. The needle is contained within a removable grip tube for
adjustability of the exposed length of the needle end, the needle further
including a stabilization mechanism limiting the movements of the needle
to linear reciprocating motion. The device includes an open design for
easy removal and replacement of device components and allows for
utilization of varying dimensioned components such as tubes, needles, and
motors available from a variety of manufacturers.
