Abstract
Abstract Disclosed herein is a stern drive unit comprising a bellows enclosure defined by a bellows connected between a support adapted to be fixed relative to a boat hull and a tilt housing connected to the support for pivotal movement about a tilt axis, an input shaft extending in the support perpendicularly to the tilt axis, an output shaft journaled in the housing and extending perpendicularly to the tilt axis in generally co-planar relation to the input shaft, a propulsion leg which includes a rotatably mounted propeller connected to the output shaft and which is connected to the tilt housing for pivotal steering movement about an axis co-axial with the output shaft, a reversing transmission located within the bellows enclosure and connected to the input and output shafts for selectively controlling operation of the propeller and including an actuating lever located forwardly of the support, a shock absorber connected between the tilt housing and the support and extending, at least in part, within the bellows enclosure, and a steering control linkage connected to the steerable propulsion leg and extending, at least in part, in the bellows enclosure and including an actuating member located forwardly of the support, and a universal coupling located within the bellows enclosure and connecting two steering control shafts extending radially of the tilt axis.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
124 words
A universal joint comprising first and second members each having a fork-shaped portion including a concave surface, one of said fork-shaped portions including a pair of spaced forks and a slot located between said forks and extending radially outwardly with respect to said concave surface, and means for adjusting the size of said slot to thereby adjust the distance between said forks and to adjust the axial distance between said members, and a connecting unit having a first annular groove receiving said forked portion of one of said first and second members, said connecting unit also having a second annular gRoove extending at a right angle to said first groove and receiving said forked portion of the other of said first and second members.
Claim 2
Dependent Claim
124 words
A universal joint comprising first and second members each having a fork-shaped portion including a concave surface, one of said fork-shaped portions including a pair of spaced forks and a slot located between said forks and extending radially outwardly with respect to said concave surface, and means for adjusting the size of said slot to thereby adjust the distance between said forks and to adjust the axial distance between said members, and a connecting unit having a first annular groove receiving said forked portion of one of said first and second members, said connecting unit also having a second annular gRoove extending at a right angle to said first groove and receiving said forked portion of the other of said first and second members.
Claim 3
Dependent Claim
198 words
A universal joint comprising first and second members each having a fork-shaped portion including an inner concave surface and a cross section taken transversely to said concave surface and tapering outwardly in the direction radially outwardly with respect to said concave surface, third and foruth members each having opposite end portions with a concave edge and a cross section taken transversely to said concave edge and tapering outwardly in the direction radially outwardly with respect to said concave edge, fifth and sixth members each having a first annular groove with an inwardly tapering cross section, said first grooves respectively receiving said fork-shaped portions of said first and second members, said fifth and sixth members each also having s second annular groove extending at a right angle to said first groove and with an inwardly tapering cross section, said second grooves respectively receiving said end portions of said third and fourth members, and means adjustably connecting said third and fourth members to each other to adjust the interfitting relationship of said first and second member fork-shaped portions in said first grooves and to adjust the interfitting relationship of said third and fourth member end portions in said second grooves.
Claim 4
Dependent Claim
198 words
A universal joint comprising first and second members each having a fork-shaped portion including an inner concave surface and a cross section taken transversely to said concave surface and tapering outwardly in the direction radially outwardly with respect to said concave surface, third and foruth members each having opposite end portions with a concave edge and a cross section taken transversely to said concave edge and tapering outwardly in the direction radially outwardly with respect to said concave edge, fifth and sixth members each having a first annular groove with an inwardly tapering cross section, said first grooves respectively receiving said fork-shaped portions of said first and second members, said fifth and sixth members each also having s second annular groove extending at a right angle to said first groove and with an inwardly tapering cross section, said second grooves respectively receiving said end portions of said third and fourth members, and means adjustably connecting said third and fourth members to each other to adjust the interfitting relationship of said first and second member fork-shaped portions in said first grooves and to adjust the interfitting relationship of said third and fourth member end portions in said second grooves.
Claim 5
Dependent Claim
97 words
A universal joint comprising first and second members each having a fork-shaped portion including an inner concave surface, third and fourth members each having opposite end portions with a concave edge, fifth and sixth members each having a first annular groove respectively receiving said fork-shaped portion of said first and second members, said fifth and sixth members each also having a second annular groove extending at a right angle to said first groove and respectively receiving said end portions of said third and fourth members, and means adjustably connecting said third and fourth members to each other.
Claim 6
Dependent Claim
97 words
A universal joint comprising first and second members each having a fork-shaped portion including an inner concave surface, third and fourth members each having opposite end portions with a concave edge, fifth and sixth members each having a first annular groove respectively receiving said fork-shaped portion of said first and second members, said fifth and sixth members each also having a second annular groove extending at a right angle to said first groove and respectively receiving said end portions of said third and fourth members, and means adjustably connecting said third and fourth members to each other.
