Uncoupling lever
|
Roland Levin
Hi all,
I do understand how an uncoupling lever works when it lifts the pin from above to release the coupler. I don't understand how it works when the lever is under the coupler. It then has to push the pin up but wouldn't the part that is pushing the pin up lock the coupler? I tried to search with Google but I couldn't find any explanations. Can anyone help me to understand this. Is there any good illustrations on-line showing the principal inside the coupler when you have the lever under the coupler.

Simple answer, the lock ("pin") is more complex than a simple metal pin, it's actually a sliding metal block with a notch in it. So, It's accessible from either top or bottom. Bottom opperated couplers were fond to be more reliable, seemed to become standard by WWII. Dennis |

When the lift lock is pushed up, it releases the coupler to swing out in the same way. You're just pushing the part up instead of pulling it up, same part.

Dennis,
You -DO- realize that when you post a link to a page full of drawings of couplers (or whatever) to this list that you have just "wasted" several hundred hours of time (collectively, the combined time for which ever group members go look at the page just to see what is there)? "Gee, Dennis posted a link ... I think I'll see what's there ... oh goody, there are lots of drawings of lots of couplers at this link ...". And half an hour to 3 hours later we come up for air. And our wives are hollering at us for not getting our 'chores' handled. Etc., etc., etc. To the OP, Many couplers have just one "pin" that goes thru the body of the coupler and it can be operated either from the top or the bottom. - Jim |

I got my 2 CD:s with 1946 Car builders cyclopedia yesterday and found a picture of the lock. The shape made it clear how it could be push up to release the coupler. Thanks for your input.
