Abstract
Image bearing panels with interleaved strips are slidably carried by a sign base. A motor drives a crank and reciprocating arm with the arm end sequentially engageable with an abutment on each panel to shift the panel and expose the panel image. An obstruction is positionable at the completion of the last panel shifted which causes the arm to move out of its reciprocating path to engage and actuate linkage acting on the panels to collectively reposition the panels preparatory to the start of a viewing sequence.
Claims11
A sign providing sequential displays, said sign comprising,
- a base,
- panel support means on said base,
- panels each including a margin extending lengthwise of each panel and each panel including a multitude of strips having a composite image thereon, the strips of one panel being slidably interleaved with strips of the remaining panels in a predetermined order, carrier means on a margin of each panel and including an abutment,
- a panel drive mechanism including power source, a crank driven by said power source, a panel drive arm carried by said crank and driven in a reciprocating manner thereby, said drive arm having a distal end for momentary sequential engagement with each carrier means abutment to shift each panel along said panel support means from a first position to a second position to displace the image bearing strips of each panel into view, and
- a panel return mechanism on said base serving to collectively return the shifted panels from said second position to said first position.

- a panel drive mechanism having a power source, a panel drive arm powered in a reciprocating manner and sequentially engageable with said abutment on each of said carrier means on said panels to move the panels in sequence in one direction,
- a panel return mechanism acting on said panels to collectively shift the panels in an opposite direction, an obstruction positionable into the path of said drive arm to alter arm travel for arm engagement with said panel return mechanism to actuate the latter.
