Case-2565 BELT TENSIONING ASSEMBLY FOR A CLOTHES DRYER. ABSTRACT OF THE DISCLOSURE A belt tensioning assembling for use in a clothes dryer positions a drive belt in tensioned relation about a rotatable drum and a drive pulley mounted within the dryer housing. The belt tensioning assembly includes an idler pulley and a resilient mounting bar. The mounting bar is preferably pre-stressed to maintain the belt in aligned tensioned relation about the pulleys. The mounting bar includes a torsion arm member, a moment arm member, and a cantilevered positioning arm member onto which the idler pulley is rotatably mounted. The moment member joins one end of the positioning member to one end of the torsion member. The torsion member is secured in positioned load transfer relation with the housing. This locates the positioning member in pre- determined spaced relation to the main axis of the drive pulley so that the idler pulley may be mounted thereon. Once mounted, the idler pulley may be moved to receive the belt thereover so as to provide tension thereto. In this position the idler pulley and drive pulley are substantially positioned in mutually aligned and parallel relation. Previous belt tensioning assemblies include mounting supports for the idler pulley having many separate components taking on a relatively more complex and expensive construction than that of the mounting bar of the present assembly.
