ABSTRACT:
An injection molded plastic guard is used to enclose a coupling connection between a prime mover input shaft and a driven output shaft. The guard is comprised of two halves that are hinged together with a stainless steel pin at one end. The coupling is centered within the guard with the hinge being positioned above the coupling. The halves extend from the hinge to distal ends that are pivoted about the pin to surround and enclose the coupling. The distal ends meet underneath the coupling area and are mounted to a non-rotating base. Sleeves extend outwardly from opposing ends of the guard to surround the input and output shafts and abut against the prime mover and output device equipment. The sleeves have a vertically, elongated opening so that one guard can be used to cover many different base-to-shaft heights. Further, the length of the sleeves can be adjusted to accommodate different centerline-of-guard to equipment face distances. End caps are used when these distances are too great or if the equipment face is such that it does not abut appropriately against the respective sleeve. A shaft opening is cut into the end caps at the appropriate base-to-shaft height.
