SAFETY ATTACHMENT FOR OUTBOARD MOTORS Filed March 27. 1948 INVENTOR WALTER A. WARDIUIS ATTORNEYS Patented Apr. 15, 1952 Y 'UNITED STATES PATENT OFFICE SAFETY ATTACHMENT' IFOR UUTBOARD MOTORS .1 Claim.

ing provided with a lock-strap, having an eyed A head engaging the motor hinging bolt, that is housed infthe standard enginepintle sleeve.

.A further Object of my invention is to provide the flower `end of the lock-strap with a slot, for engagement .with and permanently pivoted tothe clip-plate.

A further objectof my invention is to provide a key control lock, for the button to prevent theftof .the engine.

`With the Vabove and other objects Vin view, which will appear as the description proceeds, the invention resides in the novel construction, combination and arrangement of parts, substantially as hereinafter described, and more particularly defined by the appended claim, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim.

In the accompanying drawings is illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.

In the drawings:

Figure 1 represents a side elevation of an outboard motor, embodying the features of my invention, the same being shown attached to the stern gunwale of a boat.

Figure 2 is an enlarged fragmentary, sectional elevation of the saine, the section being indicated by line 2--2 of Figure 3.

Figure 3 `is a front face view of the same, being a section as illustrated by line 3--3 of Figure 2.

Figure 4 is a detailed cross-section as indicated by line 4--4 of Figure 3.

Figure 5 is another detailed sectional view through the lock-strap and associated parts, the same being indicated by line 5--5 of Figure 3.

Figure 6 is a longitudinal sectional View, through the lock-strap and associated parts, the section being indicated by line 6--5 of Figure 3; and

Figure 'l is a similar sectional View illustrating 2 the lock-strap and associated parts shifted to their :unlocked position.

Referring by characters to the drawing, Aindicatesa motor housing, of the Evinrude type, thefsame fbeing `attached to the stern gunwale, B, of a boat, :by a stern bracket 1I, which bracket is provided with the usual spaced .legs l.

The :motor housing has projecting therefrom a neck, `which neck terminates with `a Ahinge 'sleeve 2, seated between the flegs .I of the rstern bracket I.

The hinge `sleeve 2, vis .pivotally mounted hetween the `bracket legs byaboltt, Whichbolt engages suita'ble Vapertured lugs of :the bracket legs Il.

All of the :above-.mentioned elements form no part :ci my invention, and the standard 'stern bracket is seated over aclipplate 4, :which .clipplate '-is `provided `with countersunk apertured recesses :rior `retaining screws 5, 'as vbest indicated in -Fi'gure 4 of the drawings. The screws 5 are shielded by discs S, `which discs are carried by clamping bolts '5, in threaded connection ywith he lower ends of the bracket legs I', whereby the motor is firmly clamped to the stern gunwale.

My safety attachment comprises a lock-strap 8, having an eyed head 8', which head is nested within the pintle sleeve 2, in engagement with the bolt 3.

In assembling, the lock-strap, the head 8 thereof, is introduced into the sleeve 2, through an aperture 2 and thereafter the bolt 3 is properly assembled. The lock-strap 8 is secured to the bolt 3, by a set-screw 9 that is in threaded connection with the eyed head 8' and said setscrew frictionally secures the head to the pivot bolt 3.

It should be understood that in assembling the lock-strap and bolt, the said strap is swung outwardly from left to right, whereby access may be had to the set-screw through the sleeve aperture 2.

By this arrangement, when the lock-strap is in its normal position, the set-screw 9 is inaccessible.

The lower end oi' the lock-strap 8 is provided with a longitudinal slot I0 for the reception of a button Il, which button is pivotally mounted upon the screw I2. In order to provide this screw i2 as a permanent connection with the button i i, the said button is formed with a countersink, for the reception of a fluid metal cap |21', which cap cannot be removed. l

It will be noted that the slot l0 of the strap engages a projecting bed 4', whereby the strap is held against play in any direction.

As best shown in Figure 6 of the drawing, when the lock-strap is fastened to the clip-plate 4, the button I I is swung downwardly whereby the said strap is held in its secured, normal position.

In this normal position it will be noted that the motor may be used freely by authorized persons, but should it be desired to lock the motor against theft, as indicated by dotted lines Figure 3 of the drawings, any standard lock C, may be inserted through a hole II of the button, whereby it would be impossible to shift said button for the purpose of disconnecting the strap from the plate 4. As noted in Figure 7 of the drawings, when the lock C is absent, the button vcan readily be swung upon its pivot in alignment with the bed 4', whereby the strap, as indicated in dotted lines may be swung free from the clip-plate. Y

As best illustrated in Figure 6 of the drawings, the clip-plate 4 is also secured by a wood screw positioned below the locking button I I.V Thus when the lock-strap is in position the securing screw 5 is covered by the end of said strap, whereby the same is inaccessible.

From the foregoing description it is apparent that an unauthorized vperson cannot remove the motor from the gunwale ofa. boat, keeping in vmind that all of the disconnecting elements are protected, and for example it would be impossible to remove the pintle bolt 3 from its hinge sleeve, due to the fact that said bolt is positively connected to the strap head by the set screw 9.

While I have illustrated my safety attachment associated with a specific type of out-board motor, it should =be understood that said safety device is applicable to al1 types of motors, the only mechanical change beingthat the eyed head 8 of the lock-strap, may be laterally extended to meet certain conditions of the other types of motors.

I claim:

A device for locking outboard motors against accidental loss and unauthorized removal from boats of the type wherein the boat is provided with a permanently attached clip-plate, and the motor is rockably mounted upon a hinge bolt carried by a boat engaging bracket, said device comprising a strap secured to the hinge bolt for swinging movement therewith and depending therefrom over the clip-plate, an outwardly projecting rigid Ibed formed on the clip-plate below the hinge bolt and bracket, said strap having a longitudinally extending slot therein adjacent to its outer end receiving the rigid bed when the strap is swung down over the clip-plate, and an apertured button pivoted to said bed movable into and out of alignment with the bed and the slot of the strap to selectively conne or release the locking strap.
