(54) NEW OR IMPROVED SECURITY LOCKING MEANS FOR OUTBOARD MOTORS (71) We, THE BLOXWICH LOCK & BR< STAMPING COMPANY LIMITED, a British Company of P.O. Box 4, Alexander Works, Bell Lane, Bloxwich, Walsall, West Midlands WS3 2JR, do hereby declare the invention for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: This invention relates to new or improved security locking means for outboard motors.

Power boats of the larger type incorporate inboard engines but nowadays the majority of smaller power boats are propelled by outboard motors.

An outboard motor is usually detachably fitted to the transom or other part of a boat by releasable clamping means so it can be readily fitted and removed.

If a boat is to be parked or left unattended for an appreciable length of time it is desirable to remove the motor and take it to a safe place, as it is very easy for a thief to release the clamping means and steal the motor.

However, outboard motors can be of considerable weight and difficult to handle so that it is not always easy or convenient to take the motor off and store it safely, and thefts of outboard motors are common.

A usual method of mounting an outboard motor is by means of transversely spaced screw clamps provided with cross-bar or tee heads for operating them.

A securing locking means for outboard motors according to our invention comprises two co-operating telescopic tubes designed to receive a plurality of heads of spaced clamps securing a motor to the transom or other part of a boat and a key-operated lock rigidly mounted on one of the tubes for locking the tubes together after the device has been fitted on to the heads of the clamps.

Unauthorised removal of the motor is thus effectively prevented.

One preferred form of our locking device is illustrated by way of example in the accompanying drawings in which: Figure 1 is a perspective view of the device, Figure 2 is an end view of the device.

The main part of the device is a steel or other first tube 1 of sufficient diameter to receive the heads 2 of spaced clamps for securing an outboard motor to the transom or other part of a boat and of sufficient length to take in both clamps.

A longitudinal slot 3 extends for the full length of the tube and is open at one end to allow the tube to be slid over the stems 4 of the fastened clamps. The other end of the slot is closed by a part-circumferential strip 5 welded to the outside of the tube. Alternatively this end of the tube may be closed by a flanged cap.

The other part of the device is a shorter second tube 6 adapted to telescope into the first tube and to receive the heads of the clamps.

A fitting 7 welded or otherwise rigidly secured to the first tube adjacent to its open end carries a lock 8 operated by a key 9. The bolt or equivalent part of the lock engages with an aperture or notch in the second tube.

To fit the device the first tube is slid over both clamps, then the second tube is slid into the open end of the first tube over the adjacent clamp until the lock engages. On withdrawal of the key the device is securely locked in position and the motor cannot be removed.

WHAT WE CLAIM IS: 1. A securing locking device for preventing theft of outboard motors from boats comprising two co-operating telescopic tubes designed to receive a plurality of heads of spaced clamps securing a motor to the transom or other part of a boat, and a key-operated lock rigidly mounted on one of the tubes for locking the tubes together after the device has been fitted on to the heads of the clamps.

2. A securing locking device as claimed in Claim 1 in which the device comprises a longitudinally slotted tube of sufficient diameter to receive the heads of the clamps and of sufficient length to take in two clamps, a shorter tube adapted to telescope into the first tube and to receive the head of one clamp, and a key-operated lock mounted on the first tube and operative to lock the tubes together after the device has been fitted.
