This invention relates to a rail-torpedo fork
and more particularly to such a fork adapted for
the positioning of torpedoes on the rails of a
railroad track for use as a signaling device.
A primary object of this invention is the pro
vision of an improved torpedo fork which will
permit a torpedo to be placed on a rail from the
rear of a moving train.
From the foregoing, the operation of the de
vice should now be readily understood.
A conventional torpedo 23 is placed on the top
surfaces of projecting members [9, its spring
arms engaging notches 22, this operation tak

train by handle II which, it may here be pointed
