This is a mortsafe; they were created to protect your loved ones from resurrectionists who wanted to steal their corpses and sell them to medical schools. This is not an anti-vampire device.
People who were suspected of being vampires were often buried upside down. Sometimes they would have a weight on them or a stake already through them. They made have been dug up and reburied with their head at their feet, or they might have a sickle over their neck or bricks/stones under their chin. But not a cage over them.
