Abstract
Abstract The propeller shaft and the drive unit shaft in a ship''s drive system and interconnected by a coupling having two 90* offset forks, each fork having a pin whereby the pin on each fork is interposed between the respective other pin and the shaft end to which the other pin connects directly, the two pins are interconnected by a tension member.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
151 words
Shaft coupling for interconnecting two shafts and having a first fork on one shaft and a second fork on the other shaft, angularly offset by 90* to the first fork and overlapping the first fork for coupling position of the two forks, there being additional follower connection means between the two shafts in lateral offset disposition from the fork and located beyond the expected range of axial angular displacement of the shafts as it effects the disposition of the forks, the improvement comprising: a first joint on the first fork; a second joint on the second fork, the first joint disposed between the second joint and the end of the one shaft from which projects the second fork, the second joint disposed between the first joint and the end of the other shaft from which projects the first fork; and a tension member hingedly interconnecting the first and the second joint.
Claim 2
Dependent Claim
151 words
Shaft coupling for interconnecting two shafts and having a first fork on one shaft and a second fork on the other shaft, angularly offset by 90* to the first fork and overlapping the first fork for coupling position of the two forks, there being additional follower connection means between the two shafts in lateral offset disposition from the fork and located beyond the expected range of axial angular displacement of the shafts as it effects the disposition of the forks, the improvement comprising: a first joint on the first fork; a second joint on the second fork, the first joint disposed between the second joint and the end of the one shaft from which projects the second fork, the second joint disposed between the first joint and the end of the other shaft from which projects the first fork; and a tension member hingedly interconnecting the first and the second joint.
Claim 3
Dependent Claim
62 words
In a coupling as in claim 1, the forks each having two prongs, the first joint including a pin between the prongs of the fIrst fork, the second joint including a pin between the prongs of the second fork, the tension member having bores for pivotally receiving each of the pins and pivoting on the respective axis of each of the pins.
Claim 4
Dependent Claim
42 words
In a coupling as in claim 2, wherein the tension member has at least one bore having diameter larger than the one of the pin as received by the one bore, and resilient means interposed between the one pin and the bore.
Claim 5
Dependent Claim
38 words
In a coupling as in claim 3 the resilient means including a nonresilient sleeve receiving the one pin and a resilient liner secured to the bore of the tension member, the sleeve capable of turning on the pin.
