Abstract

Abstract Disclosed herein is an outboard motor having releasable means in the form of a wrap spring engaged between a king pin and a swivel bracket for preventing relative pivotal movement between the king pin and the swivel bracket. Also disclosed herein are means for releasing the wrap spring including a shaft which is pivotally carried by the king pin co-axially therewith and has means for disengaging locking engagement of the wrap spring between the king pin and the swivel bracket. Also disclosed herein are means connecting and releasing means to the king pin to effect steering movement of the outboard motor after release of the releasable means in response to the application of a steering force to said releasing means.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 460 words

Claim 2
Dependent Claim 460 words
An outboard motor comprising a swivel bracket having a bore therein, a propulsion unit, a king pin connected to said propulsion unit, and being pivotally received in said bore, and including a steering arm adapted to be pivoted by an applied force to effect common pivoting of said king pin and said propulsion unit relative to said swivel bracket, releasable means for preventing relative pivotal movement between said king pin and said swivel bracket and including an inner cylindrical surface on said swivel bracket and opposed cup members on said king pin having inner cylindrical surfaces extending continuously from said inner surface of said swivel bracket, and a wrap spring biased into engagement with each of said inner cylindrical surfaces on said cup members and on said swivel bracket and including, at the ends thereof, reversely bent hook portions each defining a bite, means for releasing said releasable means including an axial bore in said king pin and a pair of radial openings extending through said king pin and communicating with said bore, a shaft pivotally received in said bore and including an upper end extending beyond said king pin and also including axially spaced pins extending from said shaft and through said openings into engagement with said bites at the ends of said wrap spring for releasing the engagement of said spring with at least one of said swivel bracket and said king pin in response to pivoting of said shaft, a releasing bracket mounted for pivotal movement about said upper end of said shaft and about the pivot axis of said king pin and including means connected between said releasing bracket and said shaft for pivoting said shaft in response to pivoting of said releasing bracket and means adapted for receiving a steering force applied to pivot said releasing bracket, and means including a pair of spaced tabs on one of said steering arm and said releasing bracket and a projection extending between said tabs and in the path of movement of said tabs on the other of said steering arm and releasing bracket for providing a range of limited lost pivotal movement therebetween prior to effecting common pivotal movement, whereby initial pivotal movement of said bracket relative to said steering arm in response to the application of a steering force effects relative pivotal movement between said bracket and said steering arm and relative pivotal movement of said shaft relative to said king pin to effect release of the engagement of said wrap spring with at least one of said king pin aNd said swivel bracket, and whereby continued pivotal movement of said bracket effects common pivotal movement of said steering arm with said bracket to effect pivotal movement of said propulsion unit relative to said swivel bracket.
Claim 3
Dependent Claim 230 words
An outboard motor comprising a swivel bracket having a bore therein, a propulsion unit, a king pin pivotally received in said bore and connected at its upper and lower ends to said propulsion unit for common swinging movement of said propulsion unit and king pin relative to said swivel bracket, a steering arm connected to said king pin and adapted to be pivoted by an applied forece to effect common pivoting of said king pin and said propulsion unit relative to said swivel bracket, an inner cylindrical surface on said swivel bracket, opposed cup members on said king pin having inner cylindrical surfaces extending continuously from said inner surface of said swivel bracket, a single wrap spring biased into engagement with each of said inner cylindrical surfaces on said cup members and on said swivel bracket and including, at the ends thereof, reversely bent hook portions each defining a bite, an axial bore in said king pin, a pair of radial openings extending through said king pin and communicating with said bore, a shaft pivotally received in said bore and including axially spaced pins extending from said shaft and through said openings into engagement with said bites at the ends of said wrap spring for releasing the engagement of said spring with at least one of said swivel bracket and said king pin in response to pivoting of said shaft.
Claim 4
Dependent Claim 230 words
An outboard motor comprising a swivel bracket having a bore therein, a propulsion unit, a king pin pivotally received in said bore and connected at its upper and lower ends to said propulsion unit for common swinging movement of said propulsion unit and king pin relative to said swivel bracket, a steering arm connected to said king pin and adapted to be pivoted by an applied forece to effect common pivoting of said king pin and said propulsion unit relative to said swivel bracket, an inner cylindrical surface on said swivel bracket, opposed cup members on said king pin having inner cylindrical surfaces extending continuously from said inner surface of said swivel bracket, a single wrap spring biased into engagement with each of said inner cylindrical surfaces on said cup members and on said swivel bracket and including, at the ends thereof, reversely bent hook portions each defining a bite, an axial bore in said king pin, a pair of radial openings extending through said king pin and communicating with said bore, a shaft pivotally received in said bore and including axially spaced pins extending from said shaft and through said openings into engagement with said bites at the ends of said wrap spring for releasing the engagement of said spring with at least one of said swivel bracket and said king pin in response to pivoting of said shaft.
