Steam shovelIn 1839, Mr. William Smith Otis, civil engineer of Philadelphia, Penn., was issued a U.S. patent for the steam shovel (No. 1,089) for excavating and removing earth from railroads or canals. The patent drawing showed the crane mounted on a carriage or railroad car. A load of earth could be taken up by the scraper, raised by the crane and turned to be dumped, such as in railcars, and released. The patent described how a steam engine of a kind already in ordinary use, was installed with a power control mechanism for the crane, and a system of pulleys to move its arms and bucket. It could move about 380 cubic metres of earth a day, with its 1.1 cubic metre capacity shovel and 180° slewing wooden jib. It was first used on the Western Railroad in Mass.[Image: Steam shovel built by John Souther in his Globe Locomotive Works in South Boston, Mass. shown behind railcars it is loading with gravel (1857).]
A guy goes over to his friends house, rings the bell.
The wife answers the door.
"Hi, is Tony home?"
"No, he went to the store."
"Well, you mind if I wait?"
"No come in."
They sit down and the friend says, "You know Sara, you have the greatest breasts I have ever seen. I'd give you a hundred bucks if I could just see one."
Sara thinks about this for a second and figures what the hell - a hundred bucks. She opens her robe and shows one. He promptly thanks her and throws a 100 bucks on the table.
They sit there a while longer and Chris says, "They are so beautiful I've got to see the both of them. I'll give you another 100 bucks if I could just see the both of them together."
Sara thinks about this and says what the hell opens her robe and gives Chris a nice long look. Chris thanks her and throws another 100 bucks on the table then says he can't wait any longer for Tony and leaves.
A while later Tony arrives home and his wife says, "You know, your weird friend Chris came over."
Tony thinks about this for a second and says, "Well, did he drop off the 200 bucks he owes me?"
