Locking Device for Latch Hook on Gate or Door
The troublesome opening of a latch hook on a gate or door, permitting intruders to enter or possibly injuring the door in the wind, can be easily overcome by fitting a small catch over the hook, as indicated in the sketch. The U-shaped locking device is cut from a piece of tin, and fastened on the screw over which the hook is set. When locked, it is pushed back over the head of the hook, and cannot be easily jarred out of place.
