The engine 51 also conv~nt ionally includes a ~lywneel 57 and suicable means for sea~c ing the engine 51, including eicher or boch of an eleceric stareec 59 or a puL!cQpe stareer 61, bo~h shown schematically and bo~h including a ~otaeable me~ber shown fragmen~arily ae 63 in Fig. 3.

of the clu~ch dog 29 with a selected one of the forward and rearward drive beve]. gears 23 and 25 depending on the direction of movement of the shift lever 73 from the centered neutral position.
Connected to the reversing mechanism is mechanism for preventing shifting of the reversing ~ transmission 27 in the event the throttle 53 is located in an advanced setting above idle, for providing a detent action when the reversing transmiss.ion 27 in the neutral position, and for biasing the reversing transmission 27 away from the neutural position and into one of the drive positions in the event of the manual. release oE the reversing transmission 27 from the neutral position, and for precluding starting of the engine 51 in the event the reversing transmission 27 is not in neutral.
Various means can be provided for preventing shifting of the reversing transmission 27 when the throttle 53 is in an advanced position spaced from the idle position. In the disclosed construction, such means comprises a plunger 81 which is guided for movement, near the upper end thereof, by passage through an aperture in a bracket 83 fixed to the power head 17 and which is also guided, adjacent the lower end thereof, by suitable guide means. While various arrangements can be employed, in the disclosed construction, such guide means comprises a pair of spaced legs 85 which define a groove 87 receiving the ., lower end of the plunger 81 and which are formed on 30 the free end of a detent lever 91 which is mounted for rotary or pivotal mGVement on a stud 93 extending - 9 ~ ?z~
fixedly from a mounting bracket 95 fixed on the power head 17.
The lower end of the plunger 81 is connected to an arm 97 extending fixedly from the transmission control shaft 71 by a link 99 having, at its lower end, a pivotal connection with the arm 97. At its upper end! the link 99 includes a bent portion 101 which extends through a mating aperture 103 in the lower end of the plunger 81 and through aligned elongated arcuate apertures 105 in the spaced legs 85 of the detent lever 91. More specifically, the arcuate apertures 105 extend along a centerline 107 which extends at a common radius from the stud 93.
Accordingly, the link 99 is connected to the plunger 81 for pivotal movement therebetween and the plunger 81 and the link 99 are connected to the detent lever 91 for relative sliding movement within the apertures 105.
The means for preventing movement of the reversing transmission 27 into neutral in the event the thro~tle 53 is advanced beyond the idle setting also includes, in addition to the link 99 and the plunger 81 already described, interengaging surfaces on the timer plate 55 and on the plunger 81 which interfere to prevent upward plunger movement as the reversing transmlssion 27 is shifted toward neutral when the throttle 53 and timer plate 55 are in an ~ advance speed setting. Specifically, the timer plate : 55 includes a portion 111 which is positionable into interfering location with the respect to the upward path of the upper end of the plunger 81 when the timer plate 55 is in an advanced speed setting and -L0~ ~ 3 the plunger 81 is raised in response to movement of the transmission toward neutral~
Various means can be provided for providing a detent action when the ceversing transmission 27 is in neutraL. In the disclosed construction, such means comprises a follower 113 which is located on .~ the detent lever 91 in spaced relation from the stud 93 and which is adapted to engage a cam surface lL5 fixed on the arm 97 extending fixedly from the transmis.sion control shaft 71. The cam surface 115 includes a concavely dished central segment L17, together with end segments 119 and 121 which respectively project in opposite directions from the opposite ends of the central segment 117 and which progressively diminish in radial distance from the axis of transmission control shaft rotation with increasing distance from the central segment 117.
Means are provided for biasing the follower 113 into engagement with the cam surface 115 and, in particular, into the dished central segment 117.
While various arrangements can be employed, in the illustrated construction, such means comprises a lower annular flange 125 on the plunger 81, together with a helical spring 127 which encircles the plunger 81, which, at one end, bears against the lower annular flange 125 and which, at its other end, bears against a washer 129 which encircles the plunger 81 and rides on arcuate bearing surfaces 131 formed on the spaced legs 85 of the detent lever 91. More - 30 particularly, the bearing surfaces 131 extend at a uniform radius from a center 133 located on the 6~
aperture centerline 107. Accordingly, the plunger 81 and de~ent lever 91 are forced apart with the resul~
that the detent lever 97 is biased so as to maintain the folLower 113 in engagement with the cam surface 115 on the arm 97 extending from the transmission control shaft 71.
Various means can be provided ~or biasing the ~reversing transmission 27 away from the neutral position and into one or the other of the drive positions after manual release of the detent engagement oE the follower 113 in the dished central segment 117 of the cam surface 115. In the illustrated constructiont such means comprises, in addition to the plunger 81 and the link 99, an upper annuLar fl.ange 141 on the plun~er 81 belo~ the upper bracket 83, together with a biasing helical spring 143 which encircles the plunger 81, which, at one end 7 beacs against the upper bracket 83, and which, at the other end, bears against the upper annular flange 141, thereby urging do~n~ardly the plunger 81 and the link 99 so as to urge the transmission control shaft 71 away from the neutral position after release by the operator of the detent engagement of the follower 113 in the dished central segment 117 of the cam surface llS on the arm 97. The arcuate apertures 105 in the detent lever 91 permit movement relative thereto of the plunger 81 . and link 99.
Various means can be employed for precluding engine starting when the reversing transmission 27 is not in neutral~ In the iLlustrated construction, such means includes a control or locking lever 151 ~hich , "
-12~
is suitably movably mounted intermediate the ends thereof on the stud 93 adjacent to the detent lever 91, which is movable to and Erom a position permitting engine starting, and which prevents engine starting S when spaced from the position permitting engine starting.
-~ The means for precluding engine starting can include an electric starter switch 155 which is suitably mounted on the bracket 95 on the power head 17 and which includes an actuator or button 157 which is biased outwardly by suitable spring means 158 to an open position preventing energization of the electric starter 59. The actuator 157 is positioned for engagement by a projection 159 extending from the locking lever 151 such that, when the locking lever 151 is in the position permitting engine starting, the projection 159 engages and depresses the actuator 157 to close an energizing circuit to the electric starter 59. When the locking lever 151 is moved from the position permitting engine starting9 the actuator 157 extends and opens the switch, 155 thereby precluding `~ engine starting.
The means for precluding engine starting can also ~ include one or more abutments 161 on a rotary element, such as the rotatable member 63 or the flywheel 57, together with a plunger or blocking member 163 which is guided for movement in a bracket 165 fixed relative to the power head 17 and which is biased by a suitable spring 167 into a position in the rotary path of the abutment 161 so as to preclude engine starting. The plunger 163 is also connected to one end of a flexible ~ ~32~ ~
cable or linkage 169 which, at its other end, is connected to the end of the lockout lever 151 on the opposite side of the stud 93 from the projection 159.
Thus, the biasing spring 167 also serves to yieldable displace the lockout lever 151 away from the position permitting engine starting and so as to engage the projection 159 with the switch button or actuator 157.
As shown, the flexible cable 169 includes an inner core 171 connected to the plunger 163 and to the locking lever 151, together with an outer sheath 173 connected at its opposite ends to points fixed relative to the power head 17, such as the plunger mounting bracket 165 and the mounting bracket 95.
The locking lever 151 is displaced from the position permitting engine starting in response to operation of a follower 175 which is located on the end of the locking lever 151 remote from the end connected to the flexible cable 169 and which engages a cam surface 177 on the arm 97 extending from the transmission control shaft 71. The cam surface L77 includes a short central segment 181 which extends at a common radius from the axis of the transmission control shaft 71 and which is engaged by the follower 175 when the transmission 27 is in neutral. The cam surface 177 also includes respective side segments 183 and 185 which extend from the opposite ends of the short central segment 181 at radial distances from the axis of control shaft rotation which progressively diminish with increasing distance from the short central segment 181.
The foLlower 175 is biased into engagement with its cam surEace 177 through the force of the biasing spring 167 exerted through the cable 169, and/or through bias exerted by the actuator 157 of the switch 155. When the reversing transmission 27 is in neutral, the locking lever 151 is located against the action of t:he biasing spring 167 in the ;~ position permitting engine starting. In the event the transmission is moved from neutral, the side segments 183 and 185 of the cam surace 181 permit movement of the locking lever 151, under the influence of the biasing spring 167 and/or the influence of the switch actuator 157, away from the position permitting engine starting to thereby prevent engine starting.
When the reversing transmission 27 is moved from neutral, the locking lever 151 moves in response to the influence of the biasing spring 167 and/or the action of the switch actuator 157 from the position permitting engine starting, while at the same time, the spring 167 biases the plunger 163 to the position preventing rotation of the associated rotatable element, thereby preventing engine starting. Movement of the locking lever 151 from the engine starting position also serves to open of the starter switch 155, thereby also preventing engine starting.
Thus, the disclosed mechanism provides a detent action and feel when the reversing transmission 27 is in neutral and serves also to bias the re~ersing transmission 27 away from neutral toward a forward or reverse drive position after manual release of the detent holding the reversing transmission 27 in -15- 3L~ 6~
neutral. Still further and in addition, the mechanism prevents shifting into neutral in the event the throttle is set for a speed above idle. Still further in addition, cooperation between the cam surface 177 and the foLlower 175 in response to shifting of the transmission 27 from neutral prohibits engine starting either by way of opening a starter -i motor switch 155 or by way of permitting biased movement of the plunger 163 into interferring position with rotary movement of an element otherwise rotatable by the starting mechanism.

Various means can be provided for preventing shifting of the reversing transmission 27 when the throttle 53 is in an advanced position spaced from the idle position. In the disclosed construction, such means comprises a plunger 81 which is guided for movement, near the upper end thereof, by passage through an aperture in a bracket 83 fixed to the power head 17 and which is also guided, adjacent the lower end thereof, by suitable guide means. While various arrangements can be employed, in the disclosed construction, such guide means comprises a pair of spaced legs 85 which define a groove 87 receiving the ., lower end of the plunger 81 and which are formed on 30 the free end of a detent lever 91 which is mounted for rotary or pivotal mGVement on a stud 93 extending - 9 ~ ?z~
fixedly from a mounting bracket 95 fixed on the power head 17.
The lower end of the plunger 81 is connected to an arm 97 extending fixedly from the transmission control shaft 71 by a link 99 having, at its lower end, a pivotal connection with the arm 97. At its upper end! the link 99 includes a bent portion 101 which extends through a mating aperture 103 in the lower end of the plunger 81 and through aligned elongated arcuate apertures 105 in the spaced legs 85 of the detent lever 91. More specifically, the arcuate apertures 105 extend along a centerline 107 which extends at a common radius from the stud 93.
Accordingly, the link 99 is connected to the plunger 81 for pivotal movement therebetween and the plunger 81 and the link 99 are connected to the detent lever 91 for relative sliding movement within the apertures 105.
The means for preventing movement of the reversing transmission 27 into neutral in the event the thro~tle 53 is advanced beyond the idle setting also includes, in addition to the link 99 and the plunger 81 already described, interengaging surfaces on the timer plate 55 and on the plunger 81 which interfere to prevent upward plunger movement as the reversing transmlssion 27 is shifted toward neutral when the throttle 53 and timer plate 55 are in an ~ advance speed setting. Specifically, the timer plate : 55 includes a portion 111 which is positionable into interfering location with the respect to the upward path of the upper end of the plunger 81 when the timer plate 55 is in an advanced speed setting and -L0~ ~ 3 the plunger 81 is raised in response to movement of the transmission toward neutral~
Various means can be provided for providing a detent action when the ceversing transmission 27 is in neutraL. In the disclosed construction, such means comprises a follower 113 which is located on .~ the detent lever 91 in spaced relation from the stud 93 and which is adapted to engage a cam surface lL5 fixed on the arm 97 extending fixedly from the transmis.sion control shaft 71. The cam surface 115 includes a concavely dished central segment L17, together with end segments 119 and 121 which respectively project in opposite directions from the opposite ends of the central segment 117 and which progressively diminish in radial distance from the axis of transmission control shaft rotation with increasing distance from the central segment 117.
Means are provided for biasing the follower 113 into engagement with the cam surface 115 and, in particular, into the dished central segment 117.
While various arrangements can be employed, in the illustrated construction, such means comprises a lower annular flange 125 on the plunger 81, together with a helical spring 127 which encircles the plunger 81, which, at one end, bears against the lower annular flange 125 and which, at its other end, bears against a washer 129 which encircles the plunger 81 and rides on arcuate bearing surfaces 131 formed on the spaced legs 85 of the detent lever 91. More - 30 particularly, the bearing surfaces 131 extend at a uniform radius from a center 133 located on the 6~
aperture centerline 107. Accordingly, the plunger 81 and de~ent lever 91 are forced apart with the resul~
that the detent lever 97 is biased so as to maintain the folLower 113 in engagement with the cam surface 115 on the arm 97 extending from the transmission control shaft 71.
Various means can be provided ~or biasing the ~reversing transmission 27 away from the neutral position and into one or the other of the drive positions after manual release of the detent engagement oE the follower 113 in the dished central segment 117 of the cam surface 115. In the illustrated constructiont such means comprises, in addition to the plunger 81 and the link 99, an upper annuLar fl.ange 141 on the plun~er 81 belo~ the upper bracket 83, together with a biasing helical spring 143 which encircles the plunger 81, which, at one end 7 beacs against the upper bracket 83, and which, at the other end, bears against the upper annular flange 141, thereby urging do~n~ardly the plunger 81 and the link 99 so as to urge the transmission control shaft 71 away from the neutral position after release by the operator of the detent engagement of the follower 113 in the dished central segment 117 of the cam surface llS on the arm 97. The arcuate apertures 105 in the detent lever 91 permit movement relative thereto of the plunger 81 . and link 99.
Various means can be employed for precluding engine starting when the reversing transmission 27 is not in neutral~ In the iLlustrated construction, such means includes a control or locking lever 151 ~hich , "
-12~
is suitably movably mounted intermediate the ends thereof on the stud 93 adjacent to the detent lever 91, which is movable to and Erom a position permitting engine starting, and which prevents engine starting S when spaced from the position permitting engine starting.
-~ The means for precluding engine starting can include an electric starter switch 155 which is suitably mounted on the bracket 95 on the power head 17 and which includes an actuator or button 157 which is biased outwardly by suitable spring means 158 to an open position preventing energization of the electric starter 59. The actuator 157 is positioned for engagement by a projection 159 extending from the locking lever 151 such that, when the locking lever 151 is in the position permitting engine starting, the projection 159 engages and depresses the actuator 157 to close an energizing circuit to the electric starter 59. When the locking lever 151 is moved from the position permitting engine starting9 the actuator 157 extends and opens the switch, 155 thereby precluding `~ engine starting.
The means for precluding engine starting can also ~ include one or more abutments 161 on a rotary element, such as the rotatable member 63 or the flywheel 57, together with a plunger or blocking member 163 which is guided for movement in a bracket 165 fixed relative to the power head 17 and which is biased by a suitable spring 167 into a position in the rotary path of the abutment 161 so as to preclude engine starting. The plunger 163 is also connected to one end of a flexible ~ ~32~ ~
cable or linkage 169 which, at its other end, is connected to the end of the lockout lever 151 on the opposite side of the stud 93 from the projection 159.
Thus, the biasing spring 167 also serves to yieldable displace the lockout lever 151 away from the position permitting engine starting and so as to engage the projection 159 with the switch button or actuator 157.
As shown, the flexible cable 169 includes an inner core 171 connected to the plunger 163 and to the locking lever 151, together with an outer sheath 173 connected at its opposite ends to points fixed relative to the power head 17, such as the plunger mounting bracket 165 and the mounting bracket 95.
The locking lever 151 is displaced from the position permitting engine starting in response to operation of a follower 175 which is located on the end of the locking lever 151 remote from the end connected to the flexible cable 169 and which engages a cam surface 177 on the arm 97 extending from the transmission control shaft 71. The cam surface L77 includes a short central segment 181 which extends at a common radius from the axis of the transmission control shaft 71 and which is engaged by the follower 175 when the transmission 27 is in neutral. The cam surface 177 also includes respective side segments 183 and 185 which extend from the opposite ends of the short central segment 181 at radial distances from the axis of control shaft rotation which progressively diminish with increasing distance from the short central segment 181.
The foLlower 175 is biased into engagement with its cam surEace 177 through the force of the biasing spring 167 exerted through the cable 169, and/or through bias exerted by the actuator 157 of the switch 155. When the reversing transmission 27 is in neutral, the locking lever 151 is located against the action of t:he biasing spring 167 in the ;~ position permitting engine starting. In the event the transmission is moved from neutral, the side segments 183 and 185 of the cam surace 181 permit movement of the locking lever 151, under the influence of the biasing spring 167 and/or the influence of the switch actuator 157, away from the position permitting engine starting to thereby prevent engine starting.
When the reversing transmission 27 is moved from neutral, the locking lever 151 moves in response to the influence of the biasing spring 167 and/or the action of the switch actuator 157 from the position permitting engine starting, while at the same time, the spring 167 biases the plunger 163 to the position preventing rotation of the associated rotatable element, thereby preventing engine starting. Movement of the locking lever 151 from the engine starting position also serves to open of the starter switch 155, thereby also preventing engine starting.
Thus, the disclosed mechanism provides a detent action and feel when the reversing transmission 27 is in neutral and serves also to bias the re~ersing transmission 27 away from neutral toward a forward or reverse drive position after manual release of the detent holding the reversing transmission 27 in -15- 3L~ 6~
neutral. Still further and in addition, the mechanism prevents shifting into neutral in the event the throttle is set for a speed above idle. Still further in addition, cooperation between the cam surface 177 and the foLlower 175 in response to shifting of the transmission 27 from neutral prohibits engine starting either by way of opening a starter -i motor switch 155 or by way of permitting biased movement of the plunger 163 into interferring position with rotary movement of an element otherwise rotatable by the starting mechanism.
