  • the marine propulsion device also includes a reversing transmission shiftable between a drive condition and a neutral condition, and a linkage connecting the transmission to the bolt for displacing the bolt to the first position when the transmission is in a drive condition and for displacing the bolt to the second position when the transmission is in neutral position.
  • the invention relates generally to starter mechanisms for internal combustion engines generally and for internal combustion engines such as are included in marine propulsion devices having reversing transmissions. It has been sometimes previously possible to initiate engine starting operation when the transmission is in gear. Such operation is undesirable for various reasons including the possibility of sudden lurching of the boat supporting the marine propulsion device.
  • the invention provides a marine propulsion device comprising an engine having a starting gear, a starter including a rotatable starter shaft, a starter pinion carried on the starter shaft for movement relative to the shaft and to an engaged position in mesh with a starting gear, means for rotating the starter shaft in opposite directions, means cooperating with the starter shaft and with thel starter pinion for displacing the starter pinion to the position in mesh with the starting gear in response to rotation of the starter shaft in one direction, and means cooperating with the shaft and selectively locatable in a first position for preventing rotation of the starter shaft in the one direction and in a second position for permitting rotation of the starter shaft.
  • the bolt is connected by a cam to the transmission operating mechanism so as to cause withdrawal of the bolt from the recess when the transmission is in. neutral and thereby to allow engine starting operation of the starter mechanism, and so as to permit the bolt to move into the recess under the action ofa biasing spring when the transmission is in a drive condition, there by preventing operation of the starter mechanism.
  • the invention also provides for displacement of the bolt outwardly from the recess in the starter shaft against the action of a biasing spring in response to starter shaft rotation in the opposite direction from that which is normally effective to displace the starter pinion to the position in engagement with the starting gear.
  • a marine propulsion device including means for preventing operation of a starter mechanism when the transmission is in a drive condition.
  • a starter mechanism lockout device including a bolt which is selectively movable into and out of .a recess in a starter shaft to prevent and permit rotation thereof.

  • the starter mechanism 29 includes a housing or mounting bracket 47 which is connected to the engine block 23 and which includes a vertically extending bore 49 carrying a starter drive shaft 51. Carried by the starter drive shaft 51 for rotary and axial movement relative thereto, is a starter pinion 53 which is movable between a first or engaged or advanced position in mesh with the starting gear 27, and a second or retracted or lockout position which is located below the engaged position and out of engagement with the starting gear 27 (See FIG. 2).
  • Means are provided for rotating the starter shaft 51 to enable displacement of the starter pinion 53 to its engaged position and, when the starter pinion 53 is engaged with the starting gear 27, for initiating engine operation.
  • Such means comprises connection of the lower end of the starting shaft 51 to a pulley 57 which, in turn, has anchored thereto a pull rope (not shown).
  • the upper end of the starter shaft 51 is fixedly connected to a recoil spring 59 which is housed in a recess 61 in the mounting bracket 47 and has its other end anchored to the mounting bracket 47.
  • a recoil spring 59 which is housed in a recess 61 in the mounting bracket 47 and has its other end anchored to the mounting bracket 47.
  • the slots 71 and drive pin 79 are arranged such that, when the starter pinion 53 is located in the beforementioned retracted position, the drive pin 79 is located at the upper end of the inclined slots 71 and rotation of the starter shaft 51 in the first or counter clockwise direction as seen in FIG. 3, will result in movement of the starter pinion 53 from the retracted position to the engaged .position, followed by starting rotation of the engine.
  • the selectively locatable means is connected to the transmission 33 so as to locate such selectively locatable means in the first position when the transmission 33 is in a drive condition and so as to locate such selectively locatable means in the second position when the transmission 33 is in neutral.
  • such means includes a bore 91 extending in the bracket or housing 47 in generally radial relation to the axis of the starter shaft 51, and a bolt 93 which is axially movable in the bore 91 and whichincludes an inner end portion 95 movable relative to a recess 97 (see FIG. 3) in the starter shaft 51 between a first or inserted position in which the inner end portion 95 of the bolt 93 is located in the recess 97 to prevent rotation of the starter shaft 51 relative to the housing 47 and an outer or withdrawn or retracted position in which the inner end portion 95 of the bolt 93 is withdrawn from the recess 97 to thereby permit free rotation of the starter shaft 51 within the bracket or housing 47.
  • means are provided for biasing the bolt 93 into the inserted or first position. While various arrangements can be employed, in the illustrated and preferred construction, such means comprises providing the bore 91 with inner and outer counterbores 101 and 103 respectively and locating a helical biasing spring 105 in the inner counterbore 101 and around the bolt 93 in engagement, at its inner end, with a snap ring 107 on the bolt 93, and in engagement, at its outer end, against a retainer 109 which is threaded into the outer counterbore 103 and is centrally apertured to guide axial movement of the bolt 93.
  • the recess 97 in the starter shaft 51 is formed so as'to cause outward displacement of the bolt 93 against action of the spring 105 in response to rotation of the starter shaft 51 in the clockwise direction, as seen in FIG. 3.
  • the bore 91 is located in parallel offset relation to a radial line extending from the axis of the starter shaft 51, and the recess 97 includes spaced walls 111 and 113 which are respectively engageable, when the bolt 93 is in the inserted position, against the side of the inner end portion 95 of the bolt 93 and against the inner end of the bolt 93. Accordingly, attempted rotation of the starter shaft 51 in the counter clockwise direction, as shown in FIG.
  • means are provided for selectively locating the bolt 93 in its inserted and withdrawn positions in accordance with the condition of the transmission 33. More specifically, the transmission 33 is connected to the bolt 93 by a linkage 121 which allows the spring 105 to locate the bolt 93 in the inserted position when the transmission 33 is in a drive condition and which, when the transmission 33 is in neutral, withdraws the bolt 93 to the retracted or withdrawn position to permit starter shaft rotation in the direction which is effective to engage the starter pinion '53 with the starting gear 27.
  • the linkage 121 comprises a cam or link 123 which, at one end, is pivoted to an arm 125 extending fixedly from the shaft shift control 41 and which, at the other end, enters into a slot 127 in the outer end of the bolt 93.
  • the cam or-link 123 includes a profile 131 which includes, in series, a first recess portion 133, a raised portion 135, and a second recessed portion 137 which are arranged in series to be respectively located in the slot 127 at the outer end of the bolt 93 when the transmission 33 is in forward drive, in neutral, and in reverse drive.
  • the cam 123 is operably connected to the bolt 93 by means for retaining the cam profile 131 in the slot 127 and so as to cause withdrawal of the bolt 93 from the starter shaft recess 97 when the transmission 33 is in neutral, so as to permit insertion of the bolt 93 into the starter shaft recess 97 by the spring 105 when the transmission 33 is in forward or rearward drive, and so as to permit outward ratcheting movement of the bolt 93 in response to rotation of the starter shaft 51 in the clockwise direction, as seen in FIG. 3. While other means can be employed, in the disclosed construction, such means is in the form of a cross pin 141 which acts as a spring biased follower engaged with the profile 131. If desired, the connection between the transmission 33 and the bolt 93 could 'be positive in both directions.
  • the upper end of the link could be provided with a cam slot (not shown) which would positively control movement of the bolt 93 in accordance with the condition of the transmission 33.
  • movement of the shift lever 42 to forward or reverse drive locates the cam profile 131 so as to permit the spring 105 to insert the bolt 93 into the starter shaft recess 97 to thereby prevent starter shaft rotation which is otherwise effective to engage the starter pinion 53 with the starting gear 27 and to permit ratcheting of the bolt 93, as already mentioned, in response to clockwise rotation of the starter shaft 51.
  • Movement of the shift lever 42 to the neutral position displaces the profile 131 to withdraw the bolt 93 from the starter shaft recess 97 and thereby to permit free rotation in the counter clockwise direction which is effective to advance the starter pinion 53 to the position in engagement with the starting gear 27.
