ABSTRACT:
The drawings illustrate the principles involved in an inertial shuttle device originally constructed to operate as an optical character recognition device and adapted to rapid photocomposition.
The shuttle is a scanning device which is inherently a very uniform and smooth scanning velocity device and utilizes only a minute amount of driving power. This combination is achieved by means of energy conserving springs which reverse the head very rapidly at the end of each stroke with windage and friction losses made up by a lightweight, low inertia drive motor which itself is variable in power input by alteration of current intensity supplied to the motor.
