then attached at a second end through a swivel arrangement 27
to a second part 21 of the tether. The short tether 38 is
most preferably of a stretchable material forgiving enough to
allow a stretch ratio in the range of about 3:1 to about 4:1.
Additionally, in the batting function as illustrated in Figure
1, should the batter miss the ball with the bat and strike the
short tether, the tether will stretch during its wrapping
around the bat such that injury to the pitcher will be
prevented. An extended rubber tubing (e.g., surgical tubing)
with an internal diameter of 1/16 inches and an external
diameter of 1/4 to 5/16 inches has been found by McGuckin to
perform adequately. The short tether may be covered by a
braided material, however the weave of such braided material
should be such as to allow for the required stretch
capability. The second part 21 of the tether line (also
called an adjusting line) is preferably of a smaller light
gauge material, most preferably multibraided nylon. The
adjusting line 21 is in turn attached to the handle 19.
