(3) Transfer calipers. Transfer calipers are
used for measuring chamfered grooves or flanges. A
screw attaches a small auxiliary leaf to one of the legs,
as shown in figure 3-26. The measurement is made as
with ordinary calipers. The leaf is locked to the leg. The
legs may be opened or closed as needed to clear the
obstruction. The legs are then brought back and locked
to the leaf, restoring them to the original setting.

(4) Hermaphrodite calipers. The hermaphrodite
calipers have one straight leg ending in a sharp point, as
shown in figure 3-27. On some models this point is
removable. This leg is usually bowlegged. This caliper
is used for finding shaft centers or locating shoulders.

(5) Slide calipers. Slide pocket calipers have a
fixed jaw fastened to the end of a bar and a movable
jaw fastened to a frame which slides on this bar. The
bar has a scale on it and the frame has two index marks
labeled IN and OUT (see figure 3-28). To measure the
outside diameter of a round bar or the thickness of a flat
bar, the jaws of the caliper are opened and placed over
the stock. The movable jaw is then slid forward until the
jaws just touch the stock. The calipers may then be
removed and the dimension opposite the OUT index
mark can be read. To take an inside measurement, the
jaws are placed inside and spread apart until they just
touch the stock. The dimension may then be read as
before, using the IN index mark.
