Description: |
| Improvements to "flexible shaft couplings of the Oldham type and more particularly to improvements in the impeller or driving element of the coupling." The primary goal of the changes is to reduce cost.An Oldham coupling is used to connect two shafts that may not be perfectly in line. Each shaft end is fitted with a disc having a pin facing outward at its periphery, and in between the two discs is a middle disc with slots on either side, the slots at 90 degrees to one another. Each slot accepts the pin protruding from the disc on that side. This clever mechanism was invented by John Oldham of Dublin, either in the course of designing paddle-wheel steamships, or in his work designing printing machinery for the Bank of Ireland. Oldham obtained three patents for his steamship designs but none of them covered or described the coupling mechanism. |
