FiAure 73. PeeninA Pliers Adjustment
of the type maulers, or peening pliers. This is accomplished
as illustrated in Figure 73 and should be used only in the
area indicated.
7. End type bars are more difficult to align and some-
times fail to respond to the same treatment as those lo-
cated nearer the center of the segment. When twisting the
type bar it is possible to have the lower case on the writing
line and the upper case be too high.
A method of raising or lowering an end type bar is illus-
trated in Figures 74 and 75. Both steps are usually required
and may be accomplished in the following manner: Apply
the two type aligning wrenches as illustrated in Figure 74
to raise or lower a left-hand type bar. This will probably
cause the type bar to bind in the guide. To correct this
condition use the aligning wrenches as illustrated in Fig-
ure 75. This should correct the bind and result in the
desired amount of raising or lowering of the type face.
This method will also apply to right-hand type bars by
applying the aligning wrenches in the same manner and
reversing the motion to raise or lower a type bar.
SOLDERING TYPE SLUGS.
When a type slug becomes loose
on a type bar, it is advisable to replace the complete type
bar. It is not always possible to do this, however. Conse-
quently, it is necessary at times to resolder the type slug
to the type bar. A satisfactory soldering job requires care-
ful cleaning of the surfaces of the type bar and the type
slug to be soldered. Apply the heat to the type slug until
the solder runs down into the contact surfaces. Solder ap-
plied only around the edges of the slug will not retain the
slug on the bar.
A type soldering fixture (Figure 76) may be used to hold
a type slug in place, or to guide it into proper position
during resoldering. It is not necessary to remove the type
