Abstract: A guard assembly is provided for extending around a rotating shaft extending between a driving device and a driven device. The guard assembly includes two plastic pliable covers bent to form two cylindrical housings. One cylindrical housing is slidable within the other and movable between a retracted and an extended position. A split ring adapter is secured to one of the devices and includes a series of lugs that project through circumferential openings in one of the cylindrical housings. Additionally, there is provided an end cap secured to one of the cylindrical housings opposite the adapter plate. There is also provided a series of elongated openings provided in each cylindrical housing and one or more fasteners projecting through respective pairs of openings so as to secure one cylindrical housing to the other and to permit one of the housings to slide with respect to the other when the fasteners are loosened.

Abstract: A guard for shielding a rotating coupling interconnecting two rotating driveshafts. The coupling guard includes an arched cover sleeve formed from a flexible, planar sheet of material, preferably plastic, secured with a pair of brackets to a frame structure adjacent the rotating shaft coupling. The cover sleeve defines two opposed end openings, through which the rotating shafts extend, on opposite sides of the rotating shaft coupling. Preferably, the sheet of material forming the sleeve is scored with longitudinally running grooves, which enhance the flexibility of the sheet. Also, the coupling guard preferably includes a pair of arcuate end caps that cover the end openings and have central voids to permit the driveshafts to extend therethrough.
