Miller Hook Restoration
A modern-day reconstruction of the famous “hook.”
Here’s the Miller Hook coupler at the end of the car, unfortunately already rigged to connect to a link-and-pin coupling. That hunk of metal protruding from the coupler is not part of the Miller Hook. It is a jerry-rigged device to connect the car firmly to another with link-and-pin couplings. The original had a similar slot to allow its connection to link-and-pin equipped cars, but this would have been done with a loose link, providing a lot of “jerk-and-bang” which the restoration crew wanted to avoid.
The chain to the right connects to the uncoupling lever, the bottom end of which protrudes below the platform. The chain to the left secures the coupling pin (as in link-and-pin) so it won’t get misplaced.
The photo below shows one of the new replica Miller Hook couplers on display during the open house at the museum’s Car Shop in May 2002. The pin for link-and-pin coupling (which is secured by a chain in the photo above) protrudes from the coupler head. Note the brass face on the inside of the hook. The smoothness of this coupling face, together with its acute angle, would probably hold the couplings together well under tension without any kind of spring action. For that reason, it is probably replaceable.
