Of ball bearings. There is no
necessity for friction in the
running Of a chain; all that is
necessary to prevent it, are
four conditions: Ist.-That
the tooth shall be curved prop
eriy to enter the chain without
contact. 2d.-That the chain
shall pull exactly at a right
angle, with it, bearing surface
against the tooth. 3d.-That
the chain block shall not shift
or change its position while
passing around the sprocket.
4th.-That the tooth shall
leave the chain without the
least resistance. In order to
establish these conditions it
has been found, after much
consideration and practice, that
1t is necessary to form the
teeth with what is known as
cyclOidal curve, which in me
chanics, is the curve by fixed
point, say on the periphery of
a circle, when rolled along a
plane surface. The advantage
Of the cycloidal tooth is most
apparant when the rider is
climbing a hill or forcing his
wheel rapidly on an up grade
or against the wind. This is

how great the power applied,
