OUTBOARD MOTOR MOUNTING Paul .lay Homan, Napoleon, Ohio Application May 26, 1954, Serial No. 432,450

1 Claim. (Cl. 70-58) This invention relates to means for locking the standard form of outboard motor to the stern of a row-boat or other form of craft adapted for use with motors of this My locking device is so constructed as to be readily attached to the stern construction of `the boat, and when so attached cannot be removed after locking the motor in place, without the proper key. A simple and positive means is thus provided to insure against the possible removal of the outboard motor by unauthorized persons and theft of same.

A novel feature of my device is provided in which the lowering of the motor into place trips the lock and causes immediate and automatic locking action, the device being adapted to receive diiferent makes of outboard motors.

Other objects and advantages of the invention will hereinafter appear and for purposes of illustration, but not of limitation, an embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a partial view of the stern of a boat showing the outboard motor being lowered into the locking device;

Figure 2 is an elevation showing the locking device, with Ithe motor locked in place;

Figure 3 is a section taken on the line 3 3 of Figure 2;

Figure 4 is a top View of the locking device, before locking action has taken place;

Figure 5 is a section taken on the line 5--5 of Figure 4;

Figure 6 is a top View of the locking device, after the locking action has taken place;

Figure 7 is a section taken on the line 7-7 of Figure 6;

Figure 8 is an elevation of the locking member, removed from the casing; and

Figure 9 is a perspective view of the lock tripping element.

Referring to the drawings and particularly Figure l a boat indicated generally at 10 is provided with a substantial stern piece 11 to which is attached my novel locking means, indicated generally at 12. As shown in Figure l, fthe motor indicated generally at 13 is provided with the customary hook form of attaching clamp 14 carrying a plurality of horizontally arranged screw-clamping elements 15.

It will be noted that the locking device 12 is provided in its upper surface with a pair of laterally spaced T- shaped openings 16 and 17, these being adapted to receive the screw clamps and to permit same to be lowered into the longitudinally slotted opening 18 and the vertical opening 19, wherein they may be tightened to clamp the motor 13 securely against the stern piece 11 of the boat.

The lowering of the adjacent clamp 15 into the slot 19 moreover causes the lock to snap into closed position, as will hereinafter be described.

Figure 2 shows in elevation the locking device with the clamps 15 in locked position, and as shown in Figure 3, my locking device is provided with a substantial metallic back plate 20 against which the contact members 15a of the screw clamps 15, are adapted to exert pressure, thus gripping the stern piece 11 between the plate 20 and the motor attaching clamp 14.

The locking device 12 is permanently Xed to the stern piece of the boat by means of a plurality of screws 21, passing through the back plate 20 into the wood thereof, and so positioned that access to the heads of the screws cannot be had for removal when the device is locked.

It will also be noted in Figure 2 that the length of the opening 18 in the front panel of the lock 12, permits a variation in the transverse spacing of the screw-clamps 15, in order to provide for various types of outboard motor clamping means.

Referring to Figures 4, 5, 8 and 9 the locking device is here shown in open position ready to receive the motor clamps Ithrough the top openings 16 and 17 in the top horizontal wall of the casing 24. The locking slide member 25, individually shown in Figure 8 is adapted to slide within the casing 24, being biased into locking engagement by a coil spring 26, which engages a lug 27 on the casing 24 and a similar lug 28 on the locking member 25.

A locking latch member 29 is secured to the locking slide 25 and is operated by a key and tumbler controlled cylinder 30. The latch 29 is adapted normally to press a latching slide member 31 upward as biased by a spring 32, a lug 33 being welded to the upper wall of the casing 24 in the path of the latching member 31, whereby the locking member 25 is held in open position. An opening 34 in the latch member in this position of the slide 25 is aligned with the opening 16 in the casing, and a locking element 35 on the slide is withdrawn from the opening 17 in the casing.

The latching member 31 is formed at its lower end with a cut out portion or notch 36 in which an arm 37 on a trigger member 38 is adapted to seat in the open position of the locking device. The trigger 38 is pivoted to the casing 24 at 39 and is biased to swing upwardly by means of a hair-pin spring 40, which surrounds the pivot 39 and presses upwardly on the arm 37 of the latching member, as shown in Figure 5.

The trigger member 38 has an upstanding portion 41, which in the open position of the lock (Figure 5) covers a portion of the slot 19 in the casing 24. Thus it will be seen that :as the motor 13 is lowered in place, the screw clamp 15 will strike the portion 41 of the trigger 38. When this takes place, the trigger 38 will be depressed and rotating about pivot 39 it will carry with it the latch 31, due to the engagement of the arm 37 with the notch 36.

When the latch 31 has been carried downwardly enough to move it out of the path of the lug 33 on the top of the casing, the entire locking member 25 will be shifted into locking position by the action of spring 26, a stop 43 on the casing 24 limiting the locking movement of the locking slide 25.

The parts will then be in the positions shown in Figures 2, 6 and 7 with the clamps 15 locked within the casing by the portions 42 and 35 of the locking member 25. The parts now cannot be moved to open position due to the interference of the latch 31 with the lug 33 on the top of the casing 24. However, if the owner of the key wishes to open the device, he has only to insert the key in the tumbler cylinder 30, rotate same to slide the latch 31 downwardly out of the path of the lug 33, when he can once more slide the locking member 25 to open position against the pressure of spring 26, by moving the engaged key to the left. As shown, the cylinder 30 projects through a slot in the housing and serves as a handle for manually shifting the slide 25 to open or unlocked position.

When he has thus pushed the lock open, the latch 31 will once more be on the left side of the lug 33 and on rotating the key, it will again engage the lug as shown in Figure 5. The key can now be withdrawn and the lock will stay in open position until tripped by the trigger 38 as hereinbefore described.

An important advantage of the above structure is that it can accommodate outboard motors of diierent makes and which have different lateral spacing of the clamps 15. In case the spacing of the clamps is greater or less than that of the openings in the casing, the respective clamp is rst inserted into the elongate slot 18 and then shifted oneV way or the other until the other clamp is properly positioned with respect to the vertical casing opening 19 when it can then be dropped into place.

It will be manifest that the structure of the assembly is simple and the number of parts is reduced to a minimum so that it can be manufactured economically on a quantity basis. When the motor clamps are installed, the screws 21 which secure the unit to the boat, are covered so that access to them cannot be had unless the motor is removed,Y

to the housing, a spring urging said trigger to a position where a portion thereof partially obstructs the other of said openings, a locking slide shiftably mounted in said housing, a spring urging said locking slide to a position where portions thereof obstruct the entrances to said openings, a latch member carried on said slide and movable relative thereto in a direction at right angles to the direction of movement of the slide,a stop in the housing against one side of which said latching member abuts to retain said slide in a position not obstructing the entrance to said openings and against the other side of which the latching member abuts to maintain the slide in a position obstructing the entrances tor said openings, a spring urging said latch member into a position aligned with said stop, said latching member having a notched portion receiving the face end of said trigger whereby the latching member is retracted from alignment with said stop when trigger is depressed by the motor clamping screws upon insertion of the latter in said openings, a second horizontal elongated slot in the side of said housing, and means extended through said second slot and connected to said latching means for movement of said latching means out of alignment with said stop and subsequent movement of said slide to a position not obstructing the entrances to the openings.
