Type band marking device having electrically operable actuating means

Claim 1

In a spring and motor actuated marking device including a housing portion and a handle portion the combination comprising: means defining a marking opening in one end of said housing and said handle disposed at the opposite end, guide means longitudinally disposed within said housing, electrically actuated carrier means movable on said guide means between printing and retracted positions within said housing, said carrier including a plurality of independent marking bands arranged in side by side relation and each selectively adjustable to present a selected print character when said carrier is in said printing position, spring means connected to said carrier and said housing and urging said carrier to said printing position, electric motor means selectively connected to said carrier to move said carrier solely between said printing and retracted positions, said connection between said electric motor and said carrier including first gear means carried by said motor, a rotary member, a second gear means carried by said rotary member within said housing and drivingly connected to said first gear means, said rotary member including a substantially disc shaped body portion on the periphery of which said second gear means is mounted, means defining an opening in said disc, said opening including a straight-walled portions parallel to the diameter of said disc and an arcuated-walled portion concentric to the periphery of said disc, said arcuate-walled portion terminating at one end of said straight-walled portion and extending beyond the other end of said straight-walled portion to define a cavity at said other end of said straight-lined portion; said rotary member further including cam means disposed on the opposite side of said disc from said opening, an actuating link interconnecting said rotary member and said carrier to move said carrier between positions in response to actuation of said motor, said link including a bifurcated end portion one leg of which is disposed on and connected to each side of said carrier, a bight portion disposed between said carrier and said rotary member and a connecting rod portion including a ball-shaped member at the free end of said rod and transverse thereto, said ball-shaped member disposed within the opening in said rotary member and movable in response to rotation of said rotary member to selectively effect extension and retraction of said carrier, first switch means selectively operable to actuate said motor, said first and second gear means, said rotary member and said connecting link means, second switch means connected to said motor responsive to the position of said cam on said rotary member to deactivate said motor in response to a preselected position of said cam and said rotary member.
