Abstract
Abstract Disclosed herein is a steering mechanism for an outboard motor having a swivel bracket mounted for vertical swinging movement about a horizontal tilt pin, and a marine propulsion unit mounted for pivotal movement on the swivel bracket, the mechanism including a slide support rod connected to pivot about an axis normal to the axis of the tilt pin and a slide lock assembly connected to the marine propulsion unit and mounted for movement axially of the support rod, the slide lock assembly releasably restraining movement of the marine propulsion unit relative to the support rod from steering forces originating in the marine propulsion unit. The slide lock assembly includes a pivot pin mounted for movement axially of the support rod, a pair of levers having apertures slightly larger than the support rod, which levers are biased in angularly disposed relation on the support rod to respectively provide unidirectional restraint in opposite directions to the movement of the pivot pin with respect to the support rod and a slide block connected to a steering control member and mounted to slide on the support rod to selectively release the levers in response to steering movements originating from the steering control member.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
94 words
In an outboard motor, the combination of a clamp bracket, a swivel bracket, a tilt pin connecting said swivel bracket to said clamp bracket for vertical swinging movement of said swivel bracket relative to said clamp bracket, a propulsion unit mounted for pivotal movement on said swivel bracket about an axis transverse to the axis of said tilt pin to afford steering movement of said propulsion unit, a steering arm extending rigidly from said propulsion unit, and means for releasably connecting said steering arm to said horizontal tilt pin to releasably restrain steering movement.
Claim 2
Dependent Claim
94 words
In an outboard motor, the combination of a clamp bracket, a swivel bracket, a tilt pin connecting said swivel bracket to said clamp bracket for vertical swinging movement of said swivel bracket relative to said clamp bracket, a propulsion unit mounted for pivotal movement on said swivel bracket about an axis transverse to the axis of said tilt pin to afford steering movement of said propulsion unit, a steering arm extending rigidly from said propulsion unit, and means for releasably connecting said steering arm to said horizontal tilt pin to releasably restrain steering movement.
Claim 3
Dependent Claim
40 words
An outboard motor according to claim 1 wherein said releasable connecting means includes a support rod connected to said tilt pin and a slide lock assembly connected to said steering arm and mounted for movement axiaLly of said support rod.
Claim 4
Dependent Claim
32 words
An outboard motor according to claim 2 including means for connecting said support rod to said tilt pin for pivotal support rod movement about an axis extending radially from said tilt pin.
Claim 5
Dependent Claim
62 words
An outboard motor according to claim 2 wherein said slide lock assembly includes a pair of levers having apertures slightly larger than the diameter of said support rod, said levers being biased in angularly disposed relation on said support rod to respectively provide unidirectional restraint in opposite directions to the movement of said slide lock assembly with respect to said support rod.
Claim 6
Dependent Claim
45 words
An outboard motor according to claim 4 wherein said assembly includes a slide block adapted for connection to a remote actuator and mounted for movement axially of said support rod to selectively release said levers in response to steering movements originated by the remote actuator.
Claim 7
Dependent Claim
130 words
An outboard motor according to claim 1 wherein said connecting means includes a support rod connected to said tilt pin, a pivot pin mounted for axial movement on said support rod and pivotally connected to said steering arm, a pair of levers having apertures slightly larger than the diameter of said support rod, said levers being biased in angularly disposed relation on said support rod to respectively provide unidirectional restraint in opposite directions to the movement of said pivot pin with respect to said support rod, and a slide block mounted for movement axially of said support rod to selectively release said levers in response to steering actuated from a remote point and to move said pivot pin axially on said support rod to effect steering of said propulsion unit.
Claim 8
Dependent Claim
32 words
An outboard motor according to claim 6 including means for connecting said support rod to said tilt pin for pivotal support rod movement about an axis extending radially from said tilt pin.
Claim 9
Dependent Claim
106 words
A steering mechanism for a marine propulsion unit having a steering arm, which mechanism is adapted to be connected to a remote actuator and is mounted for pivotal movement on an axis transverse to a horizontal tilt pin, said mechanism including a support rod, means for supporting said support rod for movement with the propulsion unit, means for connecting the steering arm to said support rod for movement axially of said support rod to effect steering of the propulsion unit, and means for releasably restraining movement of said connecting means with respect to said support rod in response to steering movements originating from the propulsion unit.
Claim 10
Dependent Claim
106 words
A steering mechanism for a marine propulsion unit having a steering arm, which mechanism is adapted to be connected to a remote actuator and is mounted for pivotal movement on an axis transverse to a horizontal tilt pin, said mechanism including a support rod, means for supporting said support rod for movement with the propulsion unit, means for connecting the steering arm to said support rod for movement axially of said support rod to effect steering of the propulsion unit, and means for releasably restraining movement of said connecting means with respect to said support rod in response to steering movements originating from the propulsion unit.
Claim 11
Dependent Claim
63 words
A steering mechanism according to claim 8 wherein said restraining means includes a pair of levers having apertures slightly larger than the diameter of said support rod and including means for biasing said levers to angularly disposed positions on said support rod to respectively provide unidirectional restraint in opposite directions to the movement of said connecting means with respect to said support rod.
Claim 12
Dependent Claim
27 words
A steering mechanism according to claim 8 wherein said supporting means includes a radially extending arm mounted for pivotal movement about the axis of the tilt pin.
Claim 13
Dependent Claim
51 words
A steering mechanism according to claim 9 including a slide block adapted for connection to the remote actuator and mounted for movement axially of said support rod and having spaced flanges positioned to engage said levers for selectively releasing said levers in response to steering movements originating from the remote actuator.
