There has recently been introduced on SONS
OF the European railroads an arrangement Of
auxiliary cylinders for reversing gears for link
motions, which fits an important place, the plan
consisting OF a hand lever OF tho usual form,
with an eccentric forged on the lower end. .
strap on this eccentric being connected with the
slide valve rod OF the auxiliary cylinder. and
through this eccentric passes q weight shaft
uDon which another eccentric Is formed; the
eccentric on the hand lever forms the strap
for this inner eccentric. At both ends OF
OF, the weight shaft a lever is forged. one Of
and suspension links OF the link motion. the
other being connected with the piston rod OF the
SS%yySiiiary cylinder; The action is as follow:i

The fact, though an infrequent one. thAt
hollow ~pistons, on being heated for removal
from the rod, have Unexpectedly exploded. has
been the subject Of special investigation Ia
France, the fact appearing thst. during the last
twenty years. five such EXPLOSIVES have occurred
in French workshops in tho relocating OF these
hollow, c~ast-iTOn pistOns. II appears from he
made In this connection, thai, on ex-
aiming into the interior OF a piston which had
been In use some eleven years, there was exhib-
tied a brown substance which contained fatty
matter. oxide OF iron, peroxide OF iron. and car
