Abstract
A railroad switch actuator has a transversely extending box sleeper having a pair of ends, adapted to be secured to a pair of longitudinally extending fixed rolling rails, and adapted to slidably support a pair of longitudinally extending and transversely shiftable switch tongues. A switch rod extends transversely in the box sleeper, is connected to the tongues, is centered on a transverse axis, and is displaceable along the transverse axis to shift the tongues. A drive having an output shaft is supported on one end of the sleeper by a hinge for pivotal movement between a down position outboard of the one sleeper end and with the output shaft axially aligned with the switch rod and an up position between the sleeper ends.

A railroad switch actuator comprising:
- a transversely extending box sleeper having a pair of ends, adapted to be secured to a pair of longitudinally extending fixed rolling rails, and adapted to slidably support a pair of longitudinally extending and transversely shiftable switch tongues;
- a switch rod extending transversely in the box sleeper, connected to the tongues, centered on a transverse axis, and displaceable along the transverse axis to shift the tongues;
- a drive having an output shaft;
- and
- hinge means carrying the drive on the sleeper for pivotal movement at one of the sleeper ends between a down position outboard of the one sleeper end and with the output shaft axially aligned with the switch rod and an up position between the sleeper ends.
