Mr. and Mrs. Morrison were on a safari in Africa.
As they were walking through the jungle, a huge lion comes creeping out towards them, ready to pounce.
"Shoot!" Mrs. Morrison screamed to her husband. "Shoot!!"
"I can't!" he yelled back. "I'm all out of film!"
RefrigerationIn 1879, African-American Thomas Elkins patented a refrigerating apparatus (No. 221,222) designed for chilling or cooling food, or even, according to the patent, human corpses. A porous chilling box enveloped in fabric rests on a grated floor through which a circulation of air aids the evaporation of water supplied from a trough to the fabric. As the water evaporates, latent heat is withdrawn from the chilling box. He also held patents for a table (a dining and ironing table combined with a quilting frame, 20 Feb 1870, No. 100,020) and a commode (9 Jan 1872, No. 122,518). |
