Lock for Gasoline Tank on a Launch
Filler-Pipe Cover Lock to Prevent the Theft of Gasoline from a Motorboat
Having trouble by thefts of gasoline from the tank in my launch, I made the following device to prevent them, which proved very effective. A strap hinge, about 12 in. long, was procured, and on one wing, near the outer end, I fastened a staple made of a large nail, and near the center a large hole was drilled to fit over the pipe, or opening, to the tank. The other wing of the hinge was bent to the shape shown, and an oak block was fastened in the bend with wood screws. A hole was bored in the block to fit over the end of the pipe. A slot was cut in the same wing at the end to receive the staple. In turning the wing over to cover the pipe end, the staple was brought into position for a padlock. After locking the device, most of the screws are covered so that it is almost impossible to remove them without taking off the lock.—Contributed by Stephen H. Freeman, Klamath Falls, Oregon.
