Louver sign transmission system

A louver type sign transmission system for a louver sign comprising a plurality of parallel, rotatable, adjacent louvers each having a plurality of indicia receiving surfaces and ends, comprising, in combination, an elongated support frame having first and second sides, a plurality of transmissions mounted on said frame on a common side thereof in side-by-side relationship, each of said transmissions including a drive shaft drivingly connected to an output shaft, said drive shafts and said output shafts of said transmissions each having an axis of rotation and the axes of rotation of said drive shafts of said transmissions being substantially coincident and parallel to the length of said frame, said axes of said output shafts being substantially perpendicular to said axes of said drive shafts and said output shafts extending through said frame, each of said transmissions' drive shafts having an exteriorly accessible input end portion and an output end portion, a torque transmitting connector mounted upon each drive shaft end portion, said torque transmitting connectors mounted upon said drive shafts' input end portions drivingly interconnecting with said torque transmitting connectors mounted upon said drive shafts' output end portion of an adjacent transmission whereby a plurality of adjacent transmission drive shafts are operatively interconnected, a motor drivingly connected to one of said drive shaft end portions for rotating said interconnected drive shafts, and a louver end support mounted upon each transmission output shaft supporting a louver end, whereby said transmissions' drive shafts rotate the louver end associated therewith upon rotation of said drive shafts.
