Motor For the Launcher.
"The motor may be of any suitable kind or construction, but is
preferably an electric or gasolene motor. The winding-drum is furnished
with any suitable or customary reversing-guide to cause the line to wind
smoothly and evenly upon the drum. The line is preferably a cable
composed of flexible wire and having a cotton or other cord core to
increase its flexibility. The line extends from the drum to the flying
or gliding machine. Its free end may, if desired, be grasped and held
by the operator until the flying-machine ascends to the desired height,
when by simply letting go of the line the operator may continue his
flight free. The line, however, is preferably connected to the flying or
gliding machine directly by a trip-hook having a handle or trip lever
within reach of the operator, so that when he ascends to the required
height he may readily detach the line from the flying or gliding
machine."
