The diagram from Beard's 1897 coupler patent [1]. Janney couplers were first patented in 1873 by Eli H. Janney (U.S. patent 138,405). [2] [3] Andrew Jackson Beard was amongst various inventors that made a multitude of improvements to the knuckle coupler; [1] Beard's patents were U.S. patent 594,059 granted 23 November 1897, which then sold for approximately $50,000, and U.S. patent 624,901 ...
On April 1, 1873, Janney filed for a patent titled "Improvement in Car-Couplings" describing the knuckle-style couplers that are in use on railroads today. He was awarded U.S. patent 138,405 on April 29, 1873. [1] He died on June 16, 1912, in Alexandria, Virginia and was buried in Ivy Hill Cemetery. The City of Alexandria named one of their ...
A press brake is a special type of machine press that bends sheet metal into shape. A good example of the type of work a press brake can do is the back-plate of a computer case. Other examples include brackets, frame pieces and electronic enclosures. Some press brakes have CNC controls and can form parts with accuracy to a fraction of a ...

The function principles of the mechanic press machines differ in how to ensure the upper punch–main movement by cams, spindles-and friction drives, eccentric, knuckle-joints or by the round table principle, independent if the die-or lower punch movement is realized by cams- or eccentric systems or other mechanically or hydraulically combined systems.
