of the derailed vehicle and throws it clear of tho track. The inclined planes on the 
inside of the track enable the other wheels to jump the rails. 
Stiffening angles, with the vertical legs turnod clown so as to offer no obstruction 
to passing wheels, aro used where there exists the greatest tendency to tear up the 
deflecting angles. They are to be well spiked to the ties. 
Plates V and VI are not intended to be complete drawings in respect to detail ， 
for the spikes, fish plates &c. are omitted. These details are, however, not essential 
to a thorough understanding of the devices illustrated. 
From the ditching to tho re-railing apparatus there should bo a rail midway 
between the track rails to prevent any derailod vehicle, which passes the ditching 
apparatus, from diverging more than half tlie width of tlie gauge before reaching 
the frog point of tho re-railing apparatus. 
By the use of this combination perfect safety from derailment is insured to a 
Drulge.
