shelf couplers are the type of couplers you will see mostly on tank cars, they are designed to prevent puncturing of the tanks when involved in a derailment. in a nut shell.

The following doesn't asnwer your question, but may be helpful:

Hello Mr. Pierce, thanks for your e-mail inquiry.

"Shelf couplers" have an actual "shelf" (or hood) on the bottom or
bottom and top of the coupler head. It's a piece that "hoods" over (or
under) the coupler knuckles that prevents the couplers from slipping apart
up or down without actually uncoupling.

Prototypically they were developed for passenger cars and then later
tank cars to keep the cars coupled in case of an accident. The cars now
would just jack knife instead of crashing through each other. Passenger
safety and chemical spills were the big issues.

Also, if a coupler broke the head would stay coupled and hang in the
opposing coupler this prevented the head from dropping onto the track
causing a derailment.

Our new #118 shelf coupler represents a Type "SF" coupler which is a Type
F coupler with a top shelf.

Type F couplers (a tri lock style coupler with a bottom shelf) were used
on passenger cars beginning in 1954 and top and shelf couplers were made
mandintory for hazardous material tank cars in the earliy 1970s. Although
the top shelf coupler were undergoing tests for quite a number of years.
