4 Claims. (Cl. 70-58) This invention relates to a device for locking an outboard motor to the stern of a boat.
The invention, summarized briefly, includes a base plate mountable upon the stern of a boat at a location where it will be disposed at one side of the clamp of an outboard motor carried on said stern. A lock pin is mounted on the base to reciprocate in a horizontal path, and is spring biased normally to one position in which it extends across a part of the clamp and is received in a locking bracket mountable on the stern at the other side of said part of the clamp, thus to lock the clamp to the stern. A release pin is slidably mounted on the base for movement in a vertical path and is arranged transversely of the lock pin. The release pin has an opening which permits passage of the lock pin to its clamp engaging position when the release pin is depressed. When, however, the release pin is shifted upwardly it prevents movement of the lock pin to said position. The release pin is normally spring biased to its upper position, but is depressed by the outboard motor itself, when the outboard motor is moved downwardly to mount the same on the stern of the boat. A detent is carried by and is shiftable with the release pin, the detent being so mounted as to be disengaged from the lock pin when the release pin is in its upper position. When the release pin is in its lower position, the detent may be engaged with the lock pin to hold the lock pin in outer engagement with the Means is provided on the base and lock pin adapted to receive the hasp of a conventional lock when the lock pin is in its clamp engaging position, thus to' prevent theft of the motor.
Among important objects of the invention are the following:
First, to provide a device of the type stated which will not require modification or redesigning of the outboard motor or the boat;
Second, to provide a device of the character stated which will automatically move to a clamp enaging position responsive merely to mounting of the outboard motor on the stern of the boat;
Third, to provide a locking device for outboard motors which will not only be usable to prevent the motor from being lost accidentally from the boat while in use, but will also be usable as a locking means preventing theft of the motor; and
Fourth, to provide a locking device for outboard motors which can be constructed at a minimum of cost, will be rugged, and efiicient in operation.
Other objects will appear from the following description, the claims appended thereto, and from the annexed drawings, in which like reference characters designate like parts throughout the several views, and wherein:
Figure l is a top plan view, a boat on which the device is mounted being illustrated fragmentarily and an outboardmotor being shown in dotted lines;

Figure 8 is an enlarged detail sectional view showing the relationship of the lock and release pins in the operative position of the lock pin;
Figure 9 is a view similar to Figure 8 showing the lock and release pins in the relationship assumed thereby when the lock pin is in its inoperative position; and
Figure 10 is a perspective view of the lock pin per se.
The reference numeral 10 designates generally the sternboard of a boat. An outboard motor 12 has a clamp plate 14 supported on the edge of the sternboard, depending clamps 16 rigid with the clamp plate and extending downwardly within the boat adjacent the sternboard, and thumb screws 18 threadable through the clamps against the sternboard and provided with feet 19 engaging the sternboard.
The invention includes a rectangular, flat base plate 20 fixedly connected at its corners to the sternboard by screws 22, adjacent one of the clamps 16. That edge of the base plate 20 adjacent said clamp is provided with vertically spaced sleeves 24 rigid with the base plate. A release pin 26 is slidably mounted in the sleeves for up and down movement on the base plate. The release pin is shown per se in Figure 4, and is formed from a single piece of flat bar stock having a lower end portion 28 of reduced width merging into a wider upper end portion 30 integral at its upper end with a laterally projected extension 32 of inverted L-shape formed integrally at its free end with a horizontally disposed ear 34. The ear 34 is in the path of the motor 12, when the motor 12 is being shifted downwardly by a user to its illustrated position, preliminary to clamping of the motor to the sternboard. Therefore, movement of the motor to said position is effective to depress the release pin. The release pin is illustrated in its upper position in Figure 7. The release pin is illustrated in its depressed position in Figure 6.
Rigid with the base plate, and spaced vertically of and below the lower sleeve 24, is an apertured abutment 36 receiving the reduced lower end portion 28. A spring 38 is circurnposed about said reduced lower end portion, and is engaged at one end against the abutment 36, the other end of the spring engaging a cross pin 40 extending transversely of the release pin through an opening 41 formed in the release pin. The spring 38 is held under compression, and therefore normally biases the release pin to its upper position.
A lock pin 42 is of inverted L-shape, having an elongated horizontal leg 44 rigid at one end with a shorter, depending, vertical leg 46. The base plate has rigid therewith apertured lugs 48 spaced longitudinally of the upper edge of the base plate, the leg 44 being slidably mounted for movement in a horizontal path in said apertured lugs. A spring 50 is circumposed about leg 44, said spring being hooked at one end through the leg and being engaged at its other end against the lug 48 remote from the release pin 26. The spring 50 is under compression, and therefore normally urges the lock pin to the position thereof shown in Figure 6, that is, in the direction of the clamp of the outboard motor. The lock pin can, however, be shifted to the position thereof shown in Figure 7, against the action of the spring.
Formed in the release pin is an opening 52, and when the release pin is depressed, the opening 52 will align with the leg 44, thus to permit the leg 44 to be urged through the opening 52 under the pressure of the spring 50, to the position of the lock pin shown in Figure 6 and also in Figure 8. An inclined cam surface 54 is formed in the release pin, and has its low end in communication with opening 52, the high end of the cam surface merging into the surface of the release pin.
At its free end, the leg 44 is pointed as at 56. A locking bracket 58 is formed to an L-shape, and is rigidly secured to the sternboard 10, at that side of the engaged clamp 16 remote from the side at which the base plate is disposed. The locking bracket 58 has an opening 60 adapted to receive the pointed end 56 of the lock pin, when the lock pin is shifted to its operative position shown in Figures 6 and 8.
When the lock pin is in said operative position, an apertured lug 62 rigid with the base plate will be disposed in close proximity to a staple 64 formed on the lower or free end of the depending leg 46 of the lock pin. The hasp of a conventional lock 66 can be extended through the lug 62 and staple 64, to lock the parts in the position shown in Figure 6, thus to prevent theft of the motor 12, the lock pin being disposed, in this position of the parts, in a position in which it will engage the foot 19 of one of the thumb screws 18 (see Figure 2), thus to prevent said thumb screw from being backed off from the sternboard 10.
A detent designated generally at 68 is provided with a vertical end portion 70, and a horizontal end portion 72, said end portions being rigidly connected. The end portion 72 has its free end extended through an opening 74 formed in the lower end of the release pin, thus to cause the detent to shift with the release pin between the upper and lower positions thereof. A spring 76 is hooked at its lower end to the upper end of the end portion 70, and is hooked at its upper end to one end of a latch member 73 pivoted intermediate its ends, as at 86, upon the base plate. The other end of the latch member has a tooth 82 engageable in a notch 84 of the lock pin.
In use of the device, the parts will appear as shown in Figure 7, before mounting of the outboard motor upon the boat. When the outboard motor is positioned upon the sternboard, it will depress the lateral projection or car 34, causing the release pin to move downwardly against the resistance of spring 38. When the release pin moves downwardly, it will be moved to a position in which the opening 52 aligns with the leg 44 of the lock pin, and accordingly, under the pressure of the spring 50, the lock pin will shift to the right in Figure 6, past the adjacent clamp 16, to engage in the opening 60 of the locking bracket 58. As a result, the motor 12 will be held against accidental loss.
It is important to note, in this connection, that in the fully inoperative position of the lock pin, the detent will not be in engagement with the notch 84. This is due to the fact that the lock pin will, in the fully inoperative position of the parts shown in Figure 7, have its pointed end positioned against the sloped surface 54 of the release pin. In this position of the lock pin, the notch is disposed slightly to the right of the tooth S2 of the latch member, as shown in Figure 7. Further, in the fully inoperative position of the parts, with the lock pin retracted and with the release pin shifted to its upper position, the detent 68 will also be shifted upwardly, and as a result, the spring 76 will be fully contracted, so that no pull is exerted by spring 76 on latch member 78 tending to force the tooth 82 of the latch member upwardly against the lock pin.
As soon as the release pin is depressed, the spring 75 will, of course, be placed under tension and pressure will be exerted on the latch member tending to force the latch member upwardly into engagement with the leg 44 of the lock pin. However, the notch 84, not being engaged at this time by the latch member, will not interfere with movement of the lock pin to the right in Figure 6 or Figure 7, under the pressure of the spring 50, and the lock pin will accordingly move into locking engagement with the clamp of the outboard motor.
At such time as it is desired to remove the outboard motor, and assuming that lock 66 has been removed, one need only shift the lock pin manually to the left in Figures 6 and 7, until the notch 84 is engaged by the tooth of the latch member. The latch member will spring into the notch 84 at this time, since the spring 76 will at this point be under tension, the outboard motor still holding the release pin in its down position.
Thereafter, the outboard motor is removed, and as soon as the outboard motor is removed, spring 38 will be elfective to shift the release pin to its up position. In the up position of the release pin, spring 76 loses its tension, and urges upwardly the end of the latch member to which spring 76 is connected, depressing tooth 82 out of engagement with the notch 84. Spring 50 will accordingly be permitted to expand slightly, and will urge the lock pin 42 to the position shown in Figure 9, in engagement with the sloped surface 54. The slight movement of lock pin 42 to the right in Figure 7 which results from this action causes notch 84 to shift slightly to the right of tooth 82, so that tooth 82 will not interfere with the full movement of the lock pin into its clamp engaging position, when the outboard motor is next mounted on the boat.
From the foregoing, it will be evident that the device for locking the outboard motor 12 in its stern-supported position on the boat comprises the base 20 which is attachable to the stem 10 of the boat, the base 20 having a lock pin 42 mounted thereon for longitudinal movement in a horizontal path and adapted to engage the clamp of the motor 12 when moved in one direction, the release pin 26 which is also carried by the plate 20 and is mounted for movement thereon in a vertical path intersecting the longitudinal path of movement of the lock pin 42, the release pin aperture 52 receiving one end of the locking pin when the locking pin is in its clampengaging position and the release pin having a camming surface 54 upon which the one end of the lock pin can ride upon to enter the aperture 52, and means, ear 34, on the release pin 26 engageable by the motor 12 when the motor is moved to its stern-supported position thereby causing movement of the release pin in its vertical path permitting the one end of the lock pin 42 which will ride upon the camming surface 54 to enter the aperture 52 so as to lockingly engage the clamp of the motor 12. The clamp of the motor 12, will of course, be engaged by a portion of the lock pin 42 intermediate the ends of the shank 44 of the lock pin 42.
It is believed clear that the invention is not necessarily confined to the specific use or uses thereof described above, since it may be utilized for any purpose to which it may be suited. Nor is the invention to be necessarily limited to the specific construction illustrated and described, since such construction is only intended to be illustrative of the principles of operation and the means presently devised to carry out said principles, it being considered that the invention comprehends any minor change in construction that may be permitted within the scope of the appended claims.
