Once upon a time the governmen...

Once upon a time the government had a vast scrap yard in the middle of a desert. Congress said, "Someone may steal from it at night." So they created a night watchman position and hired a person for the job.
Then Congress said, "How does the watchman do his job without instruction?" So they created a planning department and hired two people, one person to write the instructions, and one person to do time studies.
Then Congress said, "How will we know the night watchman is doing the tasks correctly?" So they created a Quality Control department and hired two people. One to do the studies and one to write the reports.
Then Congress said, "How are these people going to get paid?" So they created the following positions, a time keeper, and a payroll officer,then hired two people.
Then Congress said, "Who will be accountable for all of these people?" So they created an administrative section and hired three people, an Administrative Officer, Assistant Administrative Officer, and a Legal Secretary.
Then Congress said, "We have had this operating for one year and we are $18,000 over budget. We must cutback overall cost."
So they laid off the night watchman.

Railway track scale patent

In 1857, the first U.S. patent for a railway track scale was issued to Thaddeus Fairbanks (No. 16,381). Such a platform scale was introduced by the E. and T. Fairbanks and Company of St. Johnsbury, Vermont. It was designed to weigh railway cars either alone or in train. The platform of the scale was fitted with two rails arranged in line with the railway track such that cars and carriages could readily be rolled on and off. The mechanism beneath was set in a pit. It was constructed with suitable levers and bearings to permit weighing a great range of loads accurately. Thaddeus and his brother built their company's scale business starting over two decades earlier with their invention of a platform scale for merchandise, which they patented 30 Jun 1831.
