Crazy Patents: Inventions That Never Made it

If you have a problem with excess bird droppings, then perhaps the 'Sanitary Appliance for Birds', could be the answer. Patented in 1959 this avian nappy is attached to a bird via a leather thong, which would presumably be emptied on a regular basis and then replaced. The target market for this product was never made clear; a pet budgerigar? Or maybe a battery hen or wild pigeon? The fact that bird droppings are still raining from the skies suggests this item never went into production.

Entrepreneurialism and inventiveness are encouraged by most governments around the world - after all, successful ideas lead to the creation of jobs, wealth and prestige, and this means that for the foreseeable future at least, creative minds throughout the UK, (from bedrooms in Birmingham, to serviced offices in London and desks in Durham) will be alive with the sound of inventors brainstorming ideas for the next big thing.
