Abstract:
A page turning device comprising:a case for supporting leaves to be turned, said case having at least one arcual slot of approximately 180 degrees in the top thereof,at least one rod passing through the arcual slot for engaging the leaves and turning them,a plurality of concentric plates each having a rod attached thereto, such that as a plate rotates the rod moves in an arc,a stationary shaft for mounting the plates on, the plates mounted one above the other on the stationary shaft, each plate independently moveable on the stationary shaft such that the rods can independently move in an arc,a bracket having a frame for turning the plates,a bracket having a spring for upward biasing of the frame for engaging the plates individually for rotating the plates on the stationary shaft in series as the frame moves upward,the plates each having an annular surface on a portion of each plate extending radially further than the rest of the plate on a portion of its circumference for engaging the bracket, such that the bracket engages the annular area of the plate and turns each plate until the annular surface is removed from interfering with upward motion of the bracket for engagement of the next plate on the stationary shaft,a rotatable carriage base attached to the case for mounting the bracket thereon, such that when the carriage base turns the bracket rotates and moves the rods turning the leaves,a means for rotating the carriage base.
