Abstract
Abstract A mobius drive belt and mobius drive belt fastener are disclosed in which a drive belt of a polygonal or curvelinear cross section is joined to itself at the butt ends to form a drive belt having one continuous driving or belt engaging surface. The drive belt is employed for transmitting power from at least one driving pulley to at least one driven pulley. The mobius drive belt fastener allows the butt ends of the belt to be rotated up to about 180° with respect to one another.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
122 words
A mobius drive belt fastener means comprising a first belt securing means, and second belt securing means, said securing means being joinable one to the other along a substantially common longitudinal axis, said securing means being rotatable with respect to one another along said longitudinal axis, said first securing means has locking surface means extending therefrom, said second securing means has locking surface engaging means for lockably engaging said locking surface, when said securing means are coupled to one another, coupling means for joining said securing means to one another along said longitudinal axis whereby said securing means when attached to the butt ends of a drive belt can be lockably rotated along said axis to form a mobius belt drive loop.
Claim 2
Dependent Claim
