intervening spaces, in the order in which
they are to appear in print, and there
after to present the line to a mold, so that
the linotypes or slugs may be cast against
and into the entire line of matrices at one
operation.
The operations are effected by a me
chanism which must be examined close
ly to be thoroughly understood. As
sorted matrices are stored III channels in
an inclined stationary magazine or holder,
and tend to slide downward out of the
magazine by reason of their gravity, but
are held i'll check by escapements, one at
the mouth of each channel. From these
escapements rods are extended down.
wards to a series of finger-keys on the
operating board. There is a special key
for each character or letter and the keys
are depressed by the operator in the
order in which the corresponding char
acters are to appear in the print. Each
time key is struck it permits single
matrix, bearing the corresponding char
acter to fall out of the mouth of the
magazine and downward through chan
nels to all inclined travelling belt, by
which the matrices are carried down.
ward one after another and delivered into
slotted assembling block in which they
are set up or composed side by side in a
line or row. A stationary box contains
series of spaces, and delivery device
connected with finger bar permits their
discharge and falling into line at their
proper places. Thus, by operating the
keys, the required matrices and spaces are
delivered one after another and assem-
bled in line in the block until it contains
all the characters necessary to complete
one line of print.
After the line of matrices is thus COM
posed it is transferred to the face of a
vertical mold wheel, through which
slot or mold proper extends from the
front to the rear face. The entire row
of characters in the nlatrix line is pre-
seuted directly opposite the face of the
mold or slot, so that when the mold is
filled with metal to produce a slug or
linotype, the metal will flow into the
matrices, which produce their respective
type characters in relief on the edge of
the casting
Behind the mold-wheel there is ar
ranged pot, in which type metal is
maintained in a molten condition by a
fame from gas-burner The pot has
a delivery mouth or channel adapted to
fit against and close the rear face of the
mold. Within the pot there is mounted
mechanically operated pump-plunger.
After the line of matrices is presented
and locked against and across the face of
the mold, the mouth of the pot is closed
against the rear side of the mold, and the
plunger then operates to force the molten
metal from the mouth of the pot into the
mold, in which it solidifes, completing
the slug or linotype. After the linotype
is thus produced, the moldwheel makes
partial revolution, turning the mold
slot from the horizontal position in which
it stood during the casting operation to a
vertical position. While the mold stands
in this position horizontal blade ad-
vances from the rear and pushes the limo
type forward out of the mold and be-
tween trimming knives into the galley in
front of the machine. A vibrating arm
advances the linotypes one after another
along into the galley, in which they are
thus assembled side by side in column
form ready for immediate use.
