Abstract
Abstract An apparatus for mounting and permitting swivel movement through 360° of an engine driven aerodynamic propeller type of propulsion and steering unit such as used on aquatic craft. The engine and propeller are mounted on a pedestal which in turn is mounted to swivel about an axis substantially normal to the boat deck. The engine throttle cable is connected to an unique universal coupling which permits axially reciprocal movement of the throttle cable, and thereby control of the engine, independent of either the position of the engine or the extent of the rotational movement of the propulsion unit relative to the platform on which it is mounted. The propeller is connected to the engine by a centrifugal clutch to permit the engine to be started and idled without operating as a propulsion device.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
285 words
Apparatus for providing fluid propulsion and steering in any direction to a craft having operator throttle and steering controls, comprising, in combination: an engine having a throttle for controlling its speed; means for mounting the engine to the craft to swivel about a substantially vertical axis for unencumbered angular rotational movement thereabout, including more than 360° in either direction from any starting point along the path of rotation; an aerodynamic propeller; a centrifugal clutch operatively attaching the propeller to the engine whereby the propeller is selectively disengaged and engaged to provide propulsive force as a function of engine speed; linkage means secured to the means for mounting the engine to the craft and adapted to be operatively connected to the operator steering control whereby the engine and propeller can be angularly positioned from any location to steer the craft; a throttle control cable having two segments with one end of one segment attached to the engine throttle and one end of the other segment connected to the operator throttle control; a universal coupling interposed between the segmented sections of the throttle control cable, said coupling having a body member and a head member rotatably secured in the body member for unrestrained rotation therein, the head member being connected to one end of the throttle control cable segment and the other throttle control cable segment attached to the body member with the other end of each segment attached to the operator throttle control and throttle, to thereby permit unlimited rotation of the head member corresponding to unlimited angular rotation of the means for mounting the engine to the craft in either direction to maintain and facilitate control of the engine speed and steering of the craft.
Claim 2
Dependent Claim
285 words
Apparatus for providing fluid propulsion and steering in any direction to a craft having operator throttle and steering controls, comprising, in combination: an engine having a throttle for controlling its speed; means for mounting the engine to the craft to swivel about a substantially vertical axis for unencumbered angular rotational movement thereabout, including more than 360° in either direction from any starting point along the path of rotation; an aerodynamic propeller; a centrifugal clutch operatively attaching the propeller to the engine whereby the propeller is selectively disengaged and engaged to provide propulsive force as a function of engine speed; linkage means secured to the means for mounting the engine to the craft and adapted to be operatively connected to the operator steering control whereby the engine and propeller can be angularly positioned from any location to steer the craft; a throttle control cable having two segments with one end of one segment attached to the engine throttle and one end of the other segment connected to the operator throttle control; a universal coupling interposed between the segmented sections of the throttle control cable, said coupling having a body member and a head member rotatably secured in the body member for unrestrained rotation therein, the head member being connected to one end of the throttle control cable segment and the other throttle control cable segment attached to the body member with the other end of each segment attached to the operator throttle control and throttle, to thereby permit unlimited rotation of the head member corresponding to unlimited angular rotation of the means for mounting the engine to the craft in either direction to maintain and facilitate control of the engine speed and steering of the craft.
Claim 3
Dependent Claim
210 words
In a pivotally mounted fluid propulsion and steering apparatus for providing a radially directed fluid propulsive force to a craft, the apparatus including an engine having means for producing the fluid propulsive force and a throttle control cable linking the engine throttle to an operator throttle control on the craft, the improvement comprising: means mounting the engine onto the craft for swiveling movement thereon to permit any desired amount of angular rotation of the engine, including more than 360° in either direction from any starting point along the path of rotation; coupling means interposed between coupling ends of segments of the control cable, said coupling means comprising a body member and a head member secured for unrestrained rotation therein, said head and body members attached to respective ones of the coupling ends and the other ends of the segments of cable attached to the engine throttle and operator throttle control to thereby permit axial movement of the cable to control the throttle setting and simultaneous unlimited rotational movement of the end of the cable connected to the engine throttle corresponding to the desired amount of angular swiveling of the propulsion and steering apparatus in either direction to maintain and facilitate control of the engine speed and steering of the craft.
Claim 4
Dependent Claim
210 words
In a pivotally mounted fluid propulsion and steering apparatus for providing a radially directed fluid propulsive force to a craft, the apparatus including an engine having means for producing the fluid propulsive force and a throttle control cable linking the engine throttle to an operator throttle control on the craft, the improvement comprising: means mounting the engine onto the craft for swiveling movement thereon to permit any desired amount of angular rotation of the engine, including more than 360° in either direction from any starting point along the path of rotation; coupling means interposed between coupling ends of segments of the control cable, said coupling means comprising a body member and a head member secured for unrestrained rotation therein, said head and body members attached to respective ones of the coupling ends and the other ends of the segments of cable attached to the engine throttle and operator throttle control to thereby permit axial movement of the cable to control the throttle setting and simultaneous unlimited rotational movement of the end of the cable connected to the engine throttle corresponding to the desired amount of angular swiveling of the propulsion and steering apparatus in either direction to maintain and facilitate control of the engine speed and steering of the craft.
Claim 5
Dependent Claim
25 words
Apparatus as set forth in claim 2, wherein: the head member is secured to the end of the cable segment leading to the engine throttle.
