- the gauge 25 shown in FIG. 2 is in the form of a commercially available resistance driven meter including a face plate having indicia 29 indicative of the permissible angular range of the propulsion unit, together with the indicator or pointer 27 which is movable relative to the indicia 29 in proportion to the current supplied to the gauge 25.
- the electrical currentsource provide direct current which is substantially of uniform potential.
- a direct current battery 31 is electrically connected to the gauge 25.
- the means for varying the electrical current supplied to the gauge 25 in response to vertical swinging movement of the propulsion unit 19 can take various forms, and includes a variable resistance 32 which is electrically connected in series with the gauge 25 and the battery 31.
- the variable resistance 32 includes a resistance coil 33 and a wiper 35 which is movably electrically connected to the resistance coil 33 to vary the effective resistance of the coil 33 in accordance with the position of the propulsion unit 19.
- variable resistance 32 is associated with a hydraulic cylinder-piston assembly or means 41 which can take various forms and which, in the disclosed construction, corresponds to the trim cylinder-piston assembly disclosed in the U.S. Borst et al patent application, Ser. No. 320,913 filed Jan. 4, l973,' which application is incorporated herein by reference.
- the hydraulic cylinder means 41 comprises a first member or cylinder 43 which is pivotally connected to one of the transom bracket 13 and swivel bracket and a second member in the form of a piston assembly 45 including a piston 47 and an operably connected piston rod 49 which is pivotally connected to the other of the transom bracket 13 and swivel bracket 15.
- the piston assembly 45 is telescopically received in the cylinder 43 and is movable therein relative to the cylinder 43 in accordance with the vertical swinging movement of the propulsion unit 19. Extending from the piston 47 in the construction shown in FIG.
- sleeve 51 which carries thereon the resistance coil 33 which is in the form of an annular winding wound around an insulating bobbin 53 and which is retained on the sleeve 51 in fixed position relative to the piston 47 by a snap ring 55.
- the wiper 35 is mounted on the cylinder 43 and is in the form of a ball contact which is retained in electrical engagement with the coil 33 by a retainer 59 which, in turn, is held inplace by a holding member 61 of insulating material.
- the retainer 59 has an inwardly open bore 63 which receives the ball contact or wiper 35 and which houses a spring 65 biasing the ball contact or wiper 35 into engagement with the coil 33. Accordingly, movement of the piston 47 within the cylinder 43 causes variation in the effective resistance of the coil 33.
- the coil 33 is grounded at one end and thereby electrically connected to the battery 31 in series with the gauge 25.
- the end of the coil 33 adjacent to the piston 47 is electrically connected to the sleeve 51 which, at its other end, is fixed to a guide 67 having an annular groove 69.
- a slider or contact 71 Located in the groove 69, as shown in FIG. 3, is a slider or contact 71 which electrically couples the end of the coil 33 adjacent to the piston 47 to the cylinder 43 and thereby to the outboard motor 11 which also serves as a ground for the battery 31.
- the piston rod 49 is movable relative to the piston 47, and the piston 47 is movable in accordance with propulsion unit movement only through the trim range or lower part of the permissible tilling or swinging movement of the propulsion unit.
- the gauge 25 is limited to portraying or indicating the angular position of the propulsion unit 19 relative to the attachment means 13 or boat hull solely within the trim range.
- the hydraulic fluid in the hydraulic cylinder means 41 is retained in the cylinder 43 solely to the right of the piston 47 and the coil 33 and ball contact or wiper 35 are located in a non-hydraulic fluid environment.
- any suitable series electrical connection between the gauge 25, variable resistance 32 and battery 31 can be employed. Also included in the circuit shown in FIG. 2 is a series connected, key operated ignition switch 73 which closes when the associated engine is operated and which opens when the associated engine is not operating.
- FIG. 4 Shown in FIG. 4 is another arrangement for providing a variable resistance or means which is variable in accordance with the position of the propulsion unit 19. More specifically, in the construction shown in FIG. 4, there is provided a first member which is in the form of a circular rack 81 and which is fixedly attached to the swivel bracket 15 by any suitable means, with the axis of the circular rack 81 coinciding with the axis of vertical swinging movement of the propulsion unit 19. Thus, the rack 81 has common pivotal movement with the swivel bracket 15 and propulsion unit 19.
- variable resistance coil 33A housed in a bracket 83 which is suitably fixed to the tilt pin 17 stationarily located relative to the transom bracket 13 or which can be suitably fixed directly to the transom bracket.
- resistance coil 33A is electrically connected to a wiper 35A which is supported by the bracket 83 for rotation about the tilt axis and which is connected to a pinion 85 engaged with the rack 81.
- the wiper 35A and coil 33A are connected in series with the battery 31 and gauge 25 in the same manner as connection of the coil 33 and wiper 35 in FIG. 2, so that the electrical current applied to the gauge 25 varies in accordance with the resistance of the coil 33A.
- a friction slip clutch is provided between the wiper 35A and the pinion 85, so that upon initial full travel of the propulsion unit 19 to to either its fully raised or fully lowered position, the wiper 35A will be automatically properly angularly located in relation to the pinion 85.
- the wiper 35A has associated therewith one or more stops (not shown) which are located so as to prevent movement of the wiper 35A beyond positions corresponding to fully elevated or fully lowered positions of the propulsion unit 19.
- the wiper 35A is carried by a shaft 86 and the clutch takes the form of an annular ring 87 which, for practical purposes, is fixed to one of the wiper shaft 86 and the interior bore of the pinion 85 and which has projections therein in frictional engagement with the other of the wiper shaft 86 and the interior bore of the pinion 85.
- the wiper 35A engages a stop prior to full travel of the propulsion unit, relative movement between the wiper shaft 86 and the pinion is permitted.
- the pinion 85 and wiper shaft 86 and connected wiper 35A move in unison.
- the indicator is operable over the full range of permissible propulsion unit vertical tilting movement.
