My dad walked me down the aisle at my third wedding.
He said, “I keep giving you away... and they keep giving you back!”
Black American inventionIn 1894, Black American inventor Fredrick J. Loudin was issued a U.S. patent for a "Key Fastener" (No.512,308). The invention was a device designed to attach to the knob-shaft or door-handle above the key-hole and fasten the door key in place in the lock by engaging with the eyed-end of the key to keep it from being turned in the lock. As the patent described, this would prevent disengaging the key, as might otherwise be done by a burglar from the outside of the door with some suitable implement, inserted through the key-hole. Loudin's first patent was issued 12 Dec 1892 for a window "Fastener for the Meeting Rails of Sashes" that permitted the window to be locked either closed or partially opened (No. 510,432). |
