A pair of end members are affixed to the ends of a pipe in parallel spaced relation extending perpendicular to the axis of the pipe. A locking device releasably locks the end members to the U-shaped clamp arms affixed to a marine outboard motor in a manner whereby the pipe covers the heads of manually operated screws threadedly movably mounted in the clamp arms for releasably affixing the motor to the stern of a boat thereby preventing unscrewing of the screws and removal of the motor from the boat.
2 Claims, 4 Drawing Figures 1 LOCK DEVICE FOR MARINE OUTBOARD MOTOR DESCRIPTION OF THE INVENTION The present invention relates to a lock device for a marine outboard motor. More particularly. the invention relates to a lock device for a marine outboard motor having substantially U-shaped clamp arms affixed thereto and accommodating the upper open sheet of the stern of a small boat therein and manually operated screws threadedly movably mounted in the clamp arms for releasably affixing the motor to the stern of the boat.
Objects of the invention are to provide a lock device of simple structure, which is inexpensive in manufacture, easily transportable. stored and used with facility and convenience, simple and convenient to apply and remove, and functions efficiently, effectively and reliably to prevent the unauthorized removal of a marine outboard motor from a small boat on which it is mounted.
In order that the invention may be readily carried into effect, it will now be described with reference to the accompanying drawing. wherein:
FIG. I is a schematic diagram of an embodiment of the lock device of the invention;
FIG. 2 is a view. partly in section, illustrating the installation of the lock device of the invention in securing an outboard motor;
FIG. 3 is a top view ofthe embodiment of FIG. I; and
FIG. 4 is a view, partly in section. taken along the lines IV-IV. of FIG. 3.
In the FIGS, the same components are identified by the same reference numerals.
The lock device of the invention is for a marine outboard motor I (FIG. 2) having substantially U-shaped clamp arms 2 (FIG. 2) and 3 (not shown in the FIGS.) affixed thereto and accommodating the upper open sheet 4 of the stern 5 ofa small boat 6 therein (FIG. 2). The marine outboard motor I also has manually operated screws 7 (FIG. 2) and 8 (not shown in the FIGS.) threadedly movably mounted in the clamp arms 2 and 3, respectively. for releasably affixing the motor to the stern 5 of the boat 6.
The lock device of the invention comprises a substantially semicylindrical pipe 9. A pair of end members 10 and 11 (FIGS. 1 and 3) are affixed to the ends 12 and 13 (FIGS. I and 3), respectively. of the pipe 9 in substantially parallel spaced relation extending substantially perpendicular to the axis 14 (FIG. 3) of said pipe.
A locking device releasably locks the end members 10 and II to the clamp arms 2 and 3 in a manner whereby the pipe 9 covers the heads I5 (FIG. 2) and I6 (not shown in the FIGS.) of the manually operated screws 7 and 8 of the motor 1. This prevents unscrewing of the manually operated screws 7 and 8 and thereby prevents removal of the motor 1 from the boat The locking device comprises a pair of slots I7 and I8 (FIG. 1) formed through the end members I0 and II, respectively, and a lock bar I9 removably passed through said slots and locked in position substantially parallel to the pipe 9, as shown in FIGS. 1 to 4. thereby preventing removal of the pipe from the heads of the screws 7 and 8. The lock bar 19 may be locked in any suitable manner such as, for example, by a padlock 20 (FIG. 1) passed through a bore 21 (FIGS. 1 and 3) formed through the lock bar 19.
While the invention has been described by means of a specific example and in a specific embodiment. I do not wish to be limited thereto. for obvious modifications will occur to those skilled in the art without departing from the spirit and scope of the invention.
I claim:
1. A lock device for a marine outboard motor having substantially U-shaped clamp arms affixed thereto and accommodating the upper open sheet of the stern of a small boat therein, and manually operated screws threadedly movably mounted in the clamp arms for releasably affixing the motor to the stern of the boat. said lock device comprising a substantially semicylindrical pipe;
a pair of end members affixed to the ends of the pipe in substantially parallel spaced relation extending substantially perpendicular to the axis of the pipe; and
locking means for releasably locking the end members to the clamp arms in a manner whereby the pipe covers the heads of the manually operated screws thereby preventing unscrewing thereof and removal of the motor from the boat.
2. A lock device as claimed in claim I, wherein the locking means comprises a pair of slots each formed through a corresponding one of the end members and a lock bar removably passed through the slots and locked in position substantially parallel to the pipe thereby preventing removal of the pipe from the heads of the screws.

Claims (2)

1. A lock device for a marine outboard motor having substantially U-shaped clamp arms affixed thereto and accommodating the upper open sheet of the stern of a small boat therein, and manually operated screws threadedly movably mounted in the clamp arms for releasably affixing the motor to the stern of the boat, said lock device comprising a substantially semicylindrical pipe; a pair of end members affixed to the ends of the pipe in substantially parallel spaced relation extending substantially perpendicular to the axis of the pipe; and locking means for releasably locking the end members to the clamp arms in a manner whereby the pipe covers the heads of the manually operated screws thereby preventing unscrewing thereof and removal of the motor from the boat.
2. A lock device as claimed in claim 1, wherein the locking means comprises a pair of slots each formed through a corresponding one of the end members and a lock bar removably passed through the slots and locked in position substantially parallel to the pipe thereby preventing removal of the pipe from the heads of the screws.
