require that the prior art reference teach the embodiments and/or
purposes described in the specification. Id.
Here, we find that Krauer teaches “a brake cable control
which includes a twist grip brake control handle mounted to an
end of a bicycle handlebar which enables rapid activation of the
brakes with minimum effort.” See column 2, lines 19-25, together
with Figures 4-6. We find that Krauer also teaches “[i]n a
preferred embodiment, an insert portion of a rotatable hand grip
and fitting supporting the cable in the handlebar member are
provided with complementary angle surfaces which, when rotated
relative to each other, pull the cable a specified distance to
activate the brakes without exerting undue bending stress on the
cable.” See column 2, lines 43-49. We find that Krauer further
teaches (column 7, lines 14-35) that:
Referring now to FIG. 12, once the rider wishes to
engage the brakes, the handle member 48' is rotated
axially about the handlebar 34. The greater the arc of
rotation, the greater separation will be created
between the fitting 130 and the insert 144 due to the
reorientation of the angled surfaces 134 and 148, which
causes axial displacement of the handle member 48' in
the direction indicated generally by the arrow 166.
Accordingly, the greater the amount of rotation, the
greater will be the pulling force exerted on the brake
44 through the extension of the cable 56. The greatest
axial displacement will occur upon a rotation of 180°
from the at rest position, however, depending upon the
adjustment of the brakes 44, less than 180° of rotation
of the handle member 48' may be necessary to exert full
