10. THE REBOUND CHECK LEVER BRACKET
is held to
the top of the rear rail by two screws in elongated. mount-
ing holes. With the tab lever held in its latched position
by hand and a tab stop firmly against the tab lever, move
the bracket until the engaging tip of the rebound check
lever clears the tab stop by
.005"
to
.015".
Generally, this
clearance must be maintained at the lower tolerance when
adjusting the longer carriage machines. Note that the lug
on the rebound check bracket serves as a guide for the
margin lever. Lock the bracket in such a manner that (
this lug does not bind or interfere with the freedom of the
margin lever (Figure
13).

11. THE TAB RACK
should be so positioned that the
front face of a set tab stop is parallel to the tip of the
tab lever and so that the carriage end plates are not
sprung. It should be adjusted left or right with the escape-
ment pawl engaged and the tab lever partly out so that (
there is a clearance between the striking face of the tab
lever and any, tab stop as follows:
14, 12
and
10
pitch,
.002"
to
.010'; 9
pitch,
.010"
to
.020"; 8
pitch,
.025"
to
.035".
It should be noted that as the pitch of the machine
becomes larger the tolerance becomes greater. Position the
right end of the tab rack front to rear by means of its
elongated mounting hole so that the tab lever will take an
equal bite on all set tab
stops~
