ABSTRACT:
Disclosed herein is an adjustable endless belt of unitary construction particularly adapted for use in high speed power transmission and commonly termed a fan belt. The belt is comprised of a length of flexible and durable polymeric material, one end thereof defining an elongated male end portion of reduced diameter and the other end having a longitudinal channel therein extending from said end a distance equal to the length of the aforesaid male elongated end portion. In defining the endless belt, the desired size is determined by extending the length of material about the pulleys upon which it is to be mounted; overlapping the two extended end portions until the desired tension and consequently belt length or size is determined; severing an equal length of material from each end; inserting the remaining extended male end portion into the channeled end; and securing the male end therein by a suitable polymeric glue.
