ABSTRACT:
This invention relates to a safety coupling such as found in boats and the like. The coupling is used to couple one shaft efficiently and safely to another flanged shaft and comprises a flange member with a keyed or splined axial opening disposed therethrough. The opening is configured to matingly engage with a second shaft which is keyed or splined and to permit a section of the second shaft to pass through the opening. A coupling plate is sandwiched between the flanged shaft and the keyed or splined flange member and is bolted to the flanged shaft. The coupling plate has a threaded opening disposed therethrough which engages the keyed or splined shaft adjacent the end thereof. The keyed or splined shaft then passes through the opening in the keyed or splined flange member and is retained in the coupling plate whereby linear displacement of the second shaft relative to the flanged shaft and coupling plate is prevented in a safe, secure and efficient manner. The flanged member is then screwed or bolted to the coupling plate (which is screwed or bolted to the flanged shaft) and thus transmits rotation of the flanged shaft to the second shaft in a safe, secure and efficient manner.
