Abstract: The present invention is directed to a compact retinoscope which telescopes to a closed position in order to allow the instrument to be stored in a pocket or pocket carrying case. As the instrument body or head is pushed downward to its closed position, a main internal sleeve travels upwards (relative to the head) to contact and swing a beam splitter mount positioned within the head of the instrument up into a stored position. In the stored position the reflecting means (beam splitter) of the device are positioned in a secured manner which provides added security against damage to the reflecting means if the instrument or carrying case is accidentally dropped. When the instrument head is pulled to its open or functional position, a wire-form spring positioned within the head biases the beam splitter mount back to its functional position.

Abstract: An improved typewriter escapement disengagement and engagement mechanism wherein a separator member disengages the escapement mechanism from the carriage rack to prevent damage to the mechanism and/or rack during transport of the typewriter. A restraining means prevents the carriage from moving while the escapement mechanism is disengaged. When the restraining means is removed causing carriage movement, the separator member is automatically removed from between the escapement mechanism and the carriage rack and the escapement mechanism is engaged.
