  • the apparatus is particularly applicable in boats which have steering controls located both in the cabin and out on a flying bridge. Generally both of the steering controls are always positively engaged with the steering mechanism of the boat and the boat can at all times be operated from either of the two stations.
  • the advantage of having dual steering stations has always been accompanied with the disadvantage of having one operable steering station which is unattended by the operator of the ship and can thereby be the cause of an accident.
  • the apparatus of the invention is for turning a shaft, and the apparatus is selectively operable by one of a plurality of control assemblies.
  • the apparatus consists of a lever arm with connecting means on the lever arm for attachment to the shaft to be turned.
  • a plurality of shift units are pivotally mounted on the arm and each is pivotally movable independent of the other.
  • a secondary lever portion is provided on each of the units to which one of the control assemblies it attachable, and clutch means are provided on the arm for selective interlocking engagement with either one of the units to permit the engaged unit and the lever arm to turn togetherindependent of the other shift unit. If the apparatus is specifically intended to be operated by one of two control assemblies then the apparatus will be provided with only first and second shift units pivotally mounted on the arm.
  • the invention also contemplates boats steering apparatus for steering a tiller shaft from one of two respective steering stations.
  • the apparatus comprises a lever arm which is attached to and extends laterally from the tiller shaft with first and second shift plates pivotally mounted on the arm and independently pivotal about the same axis.
  • the shift plates are spaced from each other and have arcuate openings formed therein.
  • Two push-pull control cable assemblies are provided and each is attached to one of the plates and is operable at a steering station.
  • a secondary lever portion is included in the respective plates for attachment to a respective push-pull cable assembly.
  • a clutch bar is reciprocably mounted on the arm and is positioned within the openings to reciprocate in selective operative engagement with either of the plates to permit the engaged plate and the lever arm to turn together independent of the other plate.
  • Connected to the clutch bar and operable at one of the steering stations is an auxiliary push-pull contr-ol cable assembly.
  • the auxiliary push-pull cable assembly provides means for moving the clutch bar into locking engagement with one of the plates whereupon the shaft can be turned by the control cable assembly at its steering station independent of the other control cable.
  • two auxiliary push-pull control cable assemblies can be operatively connected to the clutch means whereby the clutch means can be selectively engaged in either of the shift plates from both steering stations.
  • FIG. 1 is a perspective view of boat steering apparatus of the invention

Cut longitudinally in the arm and extending on both sides of the opening 12 is a narrow elongated slit 13. By providing this slit 13, the arm can easily be positioned on the shaft 11 since the size of the opening 12 can exceed the size of the shaft.
  • a transverse bore 14 is provided at the endmost portion of the arm adjacent the opening 12 and a bolt 15 extends through the bore and has a tightening nut 16 affixed thereto.
  • first and second shift plates 17 and 18 Pivotally mounted on opposite side of the flat arm 10 are first and second shift plates 17 and 18.
  • the shift plates are substantially flat irregular shaped members which are substantially matching in shape, and are aligned in overlying relationship such that they are substantially in registry with each other.
  • Arcuate openings 19 and 20 are out into each of the shift plates 17 and 18 respectively, with the arcuate cutoff segments describing an are which is equal to the arc described by rotation about the pivotal point of the plates.
  • Extending laterally from each of the unitary plates 17 and 18 are secondary lever portions 21 and 22 respectively. These secondary lever portions 21 and 22 extend for a suflicient length from the pivotal points of the plates to provide adequate leverage to pivot the plates, or the plate and the arm when they are united as will be seen, with minimal effort.
  • the plates are mounted on opposite sides of the arm 10, as shown in FIG. 3, by inserting a bolt 26 through the openings 23 and 24 of the shift plates and through the bore 25.
  • Plastic spacers 27 and 28 are positioned between the opposed flat surfaces of the arm and the first and second plates 17 and 18 respectively.
  • plastic washers 30 and 31 Between the head of the bolt 26 and the first plate 17 and between a nut 29 and the second plate 18 there are provided plastic washers 30 and 31.
  • the complete mounting assembly with the plastic spacers and washers positioned as shown and described permits free pivotal movement of each of the plates independent of the other plates with little frictional resistance, while still securely mounting them on the arm 10.
  • a rectangular opening 32 Formed in the lever arm between the bore and the end of the lever arm opposite to the end adjacent which the square opening 12 is provided, is a rectangular opening 32. Positioned in the opening and extending across the opening perpendicular to the longitudinal extension of the arm, is a rod 33.
  • a clutch bar 34 is mounted on the rod 32, with the rod extending through the center of the bar so that it is freely reciprocable on the rod.
  • the bar extends out of the rectangular opening 32 and through the arcuate openings 19 and 20 of the first and second plates 17 and 18. Cut into the plates 17 and 18 are opening into the arcuate openings 19 and 20 at substantially the peak of the are described are recessed portions and 36.
