When the line of matrices is raised to the distributor, it is necessary
that the matrices shall be separated and presented one at a time to the
distributor bar, between the threads of the horizontal carrier-screws.
This is accomplished as shown in Figs. 14 and 15. A horizontal pusher or
line-shifter _S_ carries the line of matrices forward from the elevator
bar _R_ into the so-called distributor box, containing at its opposite
sides two rails _u_, having near their forward ends shoulders _u2_,
against which the forward matrix abuts so as to prevent further advance
of the line, which is urged constantly forward by the follower or
line-shifter _S_. A vertically reciprocating lifting finger _V_ has its
upper end shouldered to engage beneath the foremost matrix, so as to
push it upward until its upper ears are lifted above the detaining
shoulder _u2_, so that they may ride forward on the upwardly inclined
inner ends of the rails, as shown in Fig. 14. The matrices thus lifted
are engaged by the screws and carried forward, and, as they move
forward, they are gradually raised by the rails until the teeth finally
engage themselves on the distributor bar _T_, from which they are
suspended as they are carried forward, over the mouth of the magazine,
until they fall into their respective channels, as shown in Fig.
