ABSTRACT:
A power take off (PTO) shaft safety retainer provides for the retention of the output end of a PTO shaft at its connection to a driven machine, in the event of accidental disconnection of the output end of the shaft from the driven machinery due to breakage of a U-joint, dislodging of a safety pin, failure of the gearbox, etc. The device essentially comprises an attachment to the relatively stationary portion of the driven machine, with an arm or strut extending therefrom and supporting a selectively openable retaining band adjusted to surround the PTO shaft near its connection with the driven machinery. The attachment and strut are axially offset from the axis of the PTO shaft, in order to avoid interference with the connection of the shaft to the drive means of the driven machinery. The attachment may be removably or permanently secured to the machinery by opposed flanges and bolts, over center latches, hinges with removable pins, or welded, etc., as desired. Similar removable attachments may be used to secure the openable retaining band about the PTO shaft. The band is supported clear of the connection end of the PTO shaft and provides clearance around the shaft, to avoid frictional contact with the shaft during operation. The device provides additional safety for various types of farm and other machinery, such as grain augers, vacuums and other farm machinery, and/or saw mills, portable or permanently assembled amusement rides, and other similar devices incorporating open shaft drives.
