COMPLETE SPECIFICATION (AMENDED).
Improvements in the Trimming Mechanism of Linotype Machines.
I, GEORGE WILLIAM MASCORD, of Falmouth Street, Glenferrie, in the Colony of
Victoria, Machinist, do hereby declare the nature of this invention and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement; —
This invention relates to nieans for trimming the slugs in linotype machines
and to means for rendering the slug cutter adjustable longitudinally so that
varying width of lines or measure may be obtained and also adjustable laterally
for employment with the various sizes of type, i.e., depth of slug.
In order to make my invention clear I will now refer to the accompanying.
sheet of drawings in which
Figure 1 shows an elevation of the mechanism.

movable parts.
"
"A" represents a metal casting upon the side of which a shoe "B" is secured
by means of countersunk screws 13" which enter recessed slots "B2" formed in
such shoe. The said screws "B" pass through the slot and are screwed into the
casting "A." Two or more of these slots and bolts may be employed.
"
Upon the shoe "B" a slug cutter "C" is mounted and adjustably secured there-

to by bolts "C" and nuts "C" the bolts pass through a longitudinal slot
in the cutter and a similar slot "B" in the shoe "B" the said bolts being set
with counter sunk heads within the shoe "B." At the end of the slug cutter "C"
and preferably in a rebate in same a slug cutting lever "D" is set such lever
being pivoted by a bolt "E" to said cutter. The short arm of the lever "D"
terminates in a cutting edge "D" which is arranged to lie in line with the cutting
face of "C" and to be moved out of position (see Figure 3,) when required. The
long arm D2" of this lever is arranged to be operated in any suitable manner
either by hand of by mechanism operating automatically with the machine. In
Figure 1, I show a curved plate "F" which is secured to the casting
(Figure 2,) and is provided with a surface "F" in line with the inside face of
the arm
D2" and having a raised portion "F2" over which the arm "D2" will
ride and by which it may rest in either of its two positions, that is, with the cutting
arm "D" open as shewn in Figure 3, or closed as shewn in Figure 1. Upon the
pivot pin "E" and on the face of the lever "D" a cutter plate "G" is set this
plate being provided for the purpose of trimming the lower or overhanging portion
of slug carrying the capital letter or letters entering the passage "H."
"G" so that it may be
The plate "G" is made movable by means of slot
adiusted to suit varving sizes of type capitals.

or knife "C" and is secured to casting "R" corresponding to "A."
"KK" shew lugs upon the casting "A," "L L." are stepped. plates or liners
which are preferably secured together by rod "LI," these pieces being inserted
between the lugs "K" and the shoe "B to secure a true equal and rapid adjust-
ment of the knife "C" parallel to the knife "J" after the first setting of the
adjusting screws M" which are then retained in position by the lock nuts "M."
A screw bolt "P" is provided for moving the shoe "B" and its cutters away from
the knife "J," this screw passes through the plate "F" and through the rod "L¹."
The operation of the mechanism is as follows:-the slug cutters "C" and "G"
being first adjusted for the size of type and width of line to be trimmed the
screws "B" and the nuts "C".being locked, the linotype machine may then
be operated to bring the matrice into position for the casting of the slug. Where
a line starts with a two line letter the lever will be first operated to rest in its
open position (Figure 3,) and held in position by "F2" so as to allow the slug
carrying such letter to pass along the passage "H" in the direction of arrow (being
first trimmed by the trimming or planing knife "G") the slug carrying the next
line of letters will have a blank space to lie beneath the two line letter of the pre-
.vious line and to obtain a clean cutting of this slug so that it will lie close up
against the succeeding one it is necessary before such slug is cast to operate
the lever "D" to bring it into the position shewn on Figure 1, the handle being
held on the opposite side of "F2" For the third and any succeeding number of
lines when no two line letter forms the initial to a line the lever will be retained
in this position, but before operating the machine to obtain a line starting with
an initial capital the lever "D" would be again brought into the position shewn
on Figure 3.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:-
-
1. In combination a pivoted lever cutter as "D," adjustable cutter plate as "G,"
and main slug cutter as "C," substantially as and for the purposes set forth.
2. In combination adjustable shoe as "B," adjustable slug cutters as
"C"
and "G," and pivoted lever cutter as "D," substantially as and for the purposes
set forth.

3. In combination adjustable shoe as "B" carrying slug cutters as C," "D"
and "G," adjustable stepped liners "L" lugged casting "K" and bolts "M," sub-
stantially as and for the purposes set forth.
4. The combination and arrangement of the whole of the parts forming my
improved complete slug cutting mechanism, substantially as herein described and
as illustrated on the accompanying drawings.
