2 Claims. (Cl. 246-216)
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
ing place upon the moving train. The fork I0
is then extended from the rear‘ of the moving
train by handle II which, it may here be pointed
