The wedge-shaped spaces or justifiers _I_ are held in a magazine _H_,
from which they are delivered at proper intervals by finger-key _J_ in
the keyboard, so that they may pass downward and assume their proper
positions in the line of matrices.
When the composition of the line is completed, the assembling elevator
_G_ is raised and the line is transferred, as indicated by dotted lines,
first to the left and then downward to the casting position in front of
the slotted mold seated in and extending through the vertical wheel _K_,
as shown in Figs. 2 and 3. The line of matrices is pressed against and
closes the front of the mold, the characters on the matrices standing
directly opposite the slot in the mold, as shown. The back of the mold
communicates with and is closed by the mouth of a melting-pot _M_,
containing a supply of molten metal and heated by a Bunsen burner
underneath. Within the pot is a vertical pump-plunger which acts at the
proper time to drive the molten metal through the perforated mouth of
the pot into the mold and into all the characters in the matrices.
