In an electric hammer that has been
devised recently the piston is of a mag
nctic material and the cylinder is COM
posed of Il series of coils, through each
of which current of electricity may DO
passed. The passage of a current through
the upper coils raises the piston. by
cutting oil the current aud trantcrring
it to the lower coils the piston is released
and drawn down. The blow may be
shortened or len ghtcnca, rs desired, by
regulating the distribution of the current
in the coils.
