While other arrangements are possible, in accordance with the invention, in the illustrated construction, such operating lever and reverse lock connecting means comprises (See FIGS.
  • a bell crank 91 which includes angularly spaced arms 93 and 97 and which is fixedly connected to the operating lever 71 for common movement therewith, together with an actuating or connecting rod 99 which, at its upper end, is pivotally connected to the bell crank arm 93 and which, at its lower end, includes a hook 11 having a bite 113 engageable with the undersurface of the cross web 51 of the bale or yoke 47.
  • Selective biasing is provided, in part, by the before mentioned reverse hook main springs 61, together with (See FIG. 4) a lighter spring 117 which is connected, at its lower end, to the cross web 51 of the bale or yoke 47 and which, at its upper end, is connected to an intermediate part of loop 112 formed on the actuating rod 99 so as to urge the actuating rod 99 downwardly relative to the swivel bracket 19 and thereby to bias the assembly of the bell crank 91 and operating lever 71 for pivotal movement.
  • the reverse lock main springs 61 also serve to bias the actuating rod 99 downwardly under certain conditions still to be explained.
  • the bell crank 91 is located (See FIG. 2) at the back of the swivel bracket 19 behind the king pin 21.
  • Fixed connection between the operating lever 71 and bell crank 91 is afforded by. a shaft 131 extending through a sleeve 133 supported in spaced bores in the swivel bracket 19.
  • Means are provided for limiting movement of the operating lever 71 in the counterclockwise direction as shown in FIG. 4 from the normal running position so as to determine or establish propulsion unit holding position (FIG. 7) of the operating lever 71.
  • such movement limiting means comprises, an ear or tang 141 (See FIGS. 2 and 3) which extends from the arm 97 of the bell crank 91 into the path of movement of the actuating rod 99 as the actuating rod 99 is lifted over and to the left as seen in FIG. 5 of the axis 78 of pivotal movement of the assembly of the operating lever 71 and bell crank 91.
  • Such movement also serves to elevate the connecting rod 99 so as to release the reverse lock 41.
  • Such engagement of the ear 141 with the actuating rod 99 coupled with movement of the propulsion unit 23 to the raised or elevated position, establishes the propulsion unit holding position of the operating lever 71.
  • the range of angular movement of the assembly of the operating lever 71 and bell crank 91 relative to the swivel bracket 19 between the normal running position and the propulsion unit position is about 135 and that when the assembly of the operating lever 71 and bell crank 91 is in the normal running position (FIG. 4), the bell crank arm 93 extends horizontally rearwardly and that when the assembly of the operating lever 71 and bell crank 91 is in the propulsion unit holding position, the bell crank arm 93 extends forwardly in the other direction from the axis 78 of the assembly of the operating lever 71 and bell crank 91.
  • movement of the assembly of the operating lever 71 and bell crank 91 involves displacing the upper end of the actuating rod 99 over center from one side to the other of the pivotal axis of the assembly of the operating lever 71 and bell crank 91, thereby elevating the actuating rod 99 to release the reverse lock 41.
  • means are also provided for connecting the operating lever 71 and the propulsion unit holding mechanism. While various means can be employed, in the illustrated construction, such means comprises interengaging means on the operating lever 71 and on the locking bracket 77 for transmitting rotary bias from the operating lever 71 to the locking bracket 77 and for pivotally displacing the operating lever 71 during movement of the propulsion unit 23 and connected swivel bracket 19 and in response to movement of the locking bracket 77. While other arrangements can be employed, in the illustrated construction, the operating lever 71 includes (See FIG. 4) two radially extending cam surfaces 151 and 153 which are axially spaced apart about 200 and which are connected at their radially inner ends by an arcuate surface 157 which is concentric with the operating lever mounting axis 78.
  • Extending from the locking bracket 77 is an actuating pin 159 which projects into adjacent relation to the surface 157 for selective engagement with the camming surfaces 151 and 153 in response to relative rotation between the operating lever 71 and the locking bracket 77.
  • the selective rotary bias supplied to the operating lever 71 through the actuating rod 99 is also applied, at certain times, through engagement of the actuating pin 127 on the locking bracket 77 with the surfaces 151 and 153 on the operating lever 71, so as to bias the locking bracket 77 for pivotal movement about its mounting on the swivel bracket 19.
  • the actuating pin 159 on the locking bracket 77 and the cam surfaces 151 and 153 on the operating lever 71 are arranged such that, when the assembly of the operating lever 71 and bell crank 91 is in the normal running position, the actuating pin 159 is in engagement with the surface 151.
  • the rotary bias applied to the assembly of the assembly of the operating lever 71 and bell crank 91 by reason of the downward force acting in the actuating rod 99 when theoperating lever 71 is in the running position also serves to bias the locking bracket 77 for clockwise movement relative to the swivel bracket 19.
  • the reverse lock 41 is held in engagement with the thrust pin 31 by the main springs 61.
  • the actuating rod 99 is located with the hook 111 at the bottom thereof spaced slightly below the cross web 51 of the reverse lock yoke or bale 47.
  • the light spring 117 connected between the bale cross web 51 and the actuating rod 99 serves to bias the actuating rod 99 downwardly to the position with the hook 111 slightly below and out of engagement with the cross web 51 of the reverse lock yoke or bale 47 and simultaneously to urge the bell crank 91 and connected operating lever 71 in the clockwise direction as seen in FIG.
  • the operating lever 71 In order to raise the propulsion unit 23, the operating lever 71 is moved from its normal running position shown in F IG. 4 in the counterclockwise direction until the ear or tang 141 (See FIGS. 2 and 3) on the bell crank arm 97 engages the actuating rod 99 to locate the operating lever 71 in an intermediate or the reverse lock release position shown in FIG. 5. In this position, the cam surfaces 151 and 153 are spaced from the actuating pin 159 extending from the locking bracket 77.
  • Movement of the operating lever 71 from the normal running position (See FIG. 4) to the reverse lock release position (See FIG, 5) serves to elevate the actuating rod 99, against the action of the main spring 61 and against the limited action of the light spring 117, so as to initially engage the bite 113 of the actuating rod 99 with the bale or yoke 47 and thereafter to elevate the bale or yoke 47 so as to release the reverse lock 41.
  • the action of the main springs 61 and the light spring 117 serves to yieldably urge the assembly of the operating lever 71 and bell crank 91 in the counterclockwise direction, as shown in FIG. 5, and thereby to releasably retain the operating lever 71 in the reverse lock release position.
  • the bias which is exerted by the main springs 61 and by the light spring 117 on the assembly of the operating lever 71 and bell crank 91, so as to urge these members in the counterclockwise direction also acts through the cam surface 153 and actuating pin 159 to bias the locking bracket 77 in the counterclockwise direction relative to its pivotal mounting on the swivel bracket 19.
  • Such movement of the locking bracket 77 is, however, restrained by engagement of the locking pin 89 with the forward edge 163 of the vertically elongated slot portion 81.
  • the main springs 61 and the light spring 117 serve to continue to bias the assembly of the operating lever 71 and bell crank 91 in the counterclockwise direction (as seen in FIGS. 5 and 6) and, due to the engagement of the cam surface 153 with the actuating pin 159, to simultaneously yieldably urge the locking bracket 77 in the counterclockwise direction about its pivotal mounting on the swivel bracket 19. As already indicated, such movement of the locking bracket 77 is prevented by engagement of the locking pin 89 with the forward edge 163 of the vertically elongated slot portion 81.
  • the locking pin 89 rides off the lower end of the forward edge 163 defining the vertically elongated slot portion 81 in the locking bracket 77 and the bias on the locking bracket 77 serves to cause movement of the locking bracket 77 in the counterclockwise direction and entry of the locking pin 89 into the forwardly projecting slot portion 83.
  • the propulsion unit 23 is thereafter permitted to slightly fall to the holding position shown in FIG.
  • the locking pin 89 engages the upper surface 90 of the projecting slot portion 83 to releasably prevent further downward movement of the propulsion unit 23 and connecting swivel bracket 19 and to thereby hold the propulsion unit 23 and connected swivel bracket 19 in the elevated position.
  • the movement of the locking bracket 77 in the counterclockwise direction relative to its mounting on the swivel bracket 19 which is effective to displace the locking pin 89 into the forwardly projecting slot portion 83 also serves to rotate the actuating pin 159 in the counterclockwise direction.
  • Such movement of the locking pin permits counterclockwise movement of the assembly of the operating lever 71 and bell crank 91 under the influence of the action of the main springs 61 and light spring 117 in the same counterclockwise direction so as to slightly rotate the assembly of the operating lever 71 and bell crank 91 in the counterclockwise direction.
  • the operating lever 71 When it is desired to return the propulsion unit 23 and connected swivel bracket 19 to the normal running or operating position and to again re-engage the reverse lock 41 with the thrust rod 31, the operating lever 71 is manually rocked in the clockwise direction until the cam surface 151 engages the actuating pin 159 on the locking bracket 77. In such position, the bell crank arm 93 is located in a depressed position below the normal running position (due to the previous rotation of the locking bracket 77 in the clockwise direction relative to the swivel bracket incident to the latter portion of the upward movement of the propulsion unit 23 and connected swivel bracket 19).
  • Such action of the light spring 117 serves also to releasably urge the assembly of the operating lever 71 and bell crank 91 inhe clockwise direction, and because of engagement with the cam surface 151 with the actuating pin 159 extending from the locking bracket 77, additionally serves to bias the locking bracket 77 in the clockwise direction relative to its pivotal mounting on the swivel bracket 19. Such movement ofthe locking bracket is restrained due to engagement of the locking pin 89 against the detent tang 87.
  • the propulsion unit 23 In order to lower the propulsion unit 23 and connected swivel bracket 19 to the normal running or operating position, the propulsion unit 23 is then slightly raised from the supported elevated position, Y which movement serves to lower the locking pin 89 in the forwardly projecting slot portion 83 in the locking bracket 77 until the locking pin 89 engages the lower surface 173 of the forwardly projecting slot portion 83, whereby the locking pin 89 is located below thedetent tang 87 and in position for movement from the forwardly projecting slot portion 83 to the bottom of the vertically elongated slot portion 81.
  • the bias exerted by the light spring 117 serves to pivot the locking bracket 77 in the clockwise direction around its pivotal mounting on the swivel bracket 19 and thereby to locate the locking pin 89 at the bottom of the vertically elongated slot portion 81 and against the rear edge 177 thereof.
  • the propulsion unit 23 and connected swivel bracket 19 can now be lowered toward the normal running position.
  • the locking pin 89 moves upwardly to the top of the vertically elongated slot portion 81 in the locking bracket 77 and, at the same time, due to the geometry of the pivot points, the locking bracket 77 is rotated in the counterclockwise direction relative to the swivel bracket 19 and against the action of the light spring 117, to return the assembly of the operating lever 71 and bell crank 91 to the normal running position (See Flg. 4) and thereby to raise the bell crank arm 93 and connected actuating rod 99.
