Not to mention having to be between the cars during the coupling.

Again I want to send Ulrich and all others to their libraries for so many books about pre and post 1900 railroading....individual railroad histories as well as broader histories...book written this morning and thousand more written since the first rail and spike were placed.  Check rail museums and rail historical societies, local historical societies, flea markets and train shows for some of the older books.  Be careful of books published for the sake of publishing or for the sake of selling books on trains...usually photo books with little editorial content and often poorly captioned pictures.  Look at the bibliography of each searching for names of authors, railroads, people, and books which you might know to anchor the information for you.  Check the ads in TRAINS, CLASSIC TRAINS, and others for new and old titles...even run down books on Ebay, Amazon, and other internet services.   Most libraries, if they don't have the book or books you are looking for, can search and find ones you might want.  Old Railroad Magazines (dating back to ca.1910) have great stories and news and pictures; TRAINS started in 1938 with some great articles.  Even Life did photo essays and Saturday Evening Post magazines did articles and fictional stories.  

RIDEWITHMEHENRY is the name for our almost monthly day of riding trains and transit in either the NYCity or Philadelphia areas including all commuter lines, Amtrak, subways, light rail and trolleys, bus and ferries when warranted. No fees, just let us know you want to join the ride and pay your fares. Ask to be on our email list or find us on FB as RIDEWITHMEHENRY (all caps) to get descriptions of each outing.

From our modern perspective, most railfans do not relate at all to the pre-1900 period.  They tend to dismiss it as the beginning times.  But it was a wild and exciting time in those teenage years of railroading in the 1880-1900 period.

The best book on the topic of this thread that I have seen is The American Railroad Freight Car by John H. White, Jr.  The diversity of rolling stock in the pioneering era is astounding.

I can just imagine railroading at some time around 1885,  in the middle of a Maine winter. It is too bad that more railroad people from that era did not leave a written record. But then again, the life expectancy for the average male was only 45 years, and he probably had no time to think about anything other than getting through the day in one piece.

Yes, the loose hardware was a big problem with link and pin couplers in addition to the widely known safety hazard.  Another problem was that link and pin couplers generally had a lot more slack than Janney couplers.  Unlike Janney couplers, link and pin couplers were not as capable of transmitting a shoving load.  So the solution was to equip cars with “deadblocks” on each side of the link and pin coupler.  To the best of my knowledge, however, deadblocks were not universal during the link and pin era. 

When shoving, the deadblocks came together and transmitted the compression force, leaving the link and pin coupler somewhat slack.  Link and pin couplers were well known to amputate fingers or hands.  Deadblocks smashed torsos.

Bite your tongue, Ulrich.  I am personally appalled that you would suggest theft was any part of American railroads in the second half of the 19th century.  Since you are European I guess I can forgive your misunderstanding of us.  But no American would ever EVER believe there was any kind of foul play connected with the development of our railroads during those years.  

DISCLAIMER:  I am fully aware of the 'whooosh' factor.

The real theft issue, according to no less an authority than C.F.Adams, was not the conversion pins for the couplers, although -- yes -- that was recognized as a significant factor, and attempts were made to address it.

A FAR more significant cost was links and pins in the link-and-pin coupling system.  There are some horror stories about employees selling a great number of "broken" links as 'old iron' to scrap dealers.  ISTR replacement link numbers upward of 20,000 per year - don't have the reference at hand to check.

I've read that theft was a big problem, with underpaid workers and others stealing the pins in order to sell them for their metal value.

A lot of good railroad history books like that of known and respected railroad authors like Jensen, Withune, and White are available at your library.

 

Sadly, not at my library. All we have are books on investing, living with same sex partners and shelves filled with books on  how to lose weight, and of course war. Some drug store fiction type books available too. I'm not sure where my tax money goes, but it ain't going to the libraries, that I can tell you for sure.

That's interesting about the hoarding of link and pin components. I've read that theft was a big problem, with underpaid workers and others stealing the pins in order to sell them for their metal value. Maybe there's some overlap between the hoarding for practical purposes and the outright theft of the pins. It must have been tough on the crews to have to deal with incompatible link & pin couplers as well as the Janney.

The slotted knuckle is the basic explanation.  However, a point that is often missed in the historical overview is that there was a considerable amount of incompatibility between link and pin couplers. There were many different designs and many required a variety of specialized connecting links and pins in order to mate.   

This led to crews hoarding the loose link and pin hardware so as to have the proper components to mate couplers.  A crew setting out twenty cars might strip all of the links and pins, and add them to their stockpile in the caboose.  The crew arriving to pick up the cars, would have to go through their stockpile to find all the necessary links and pins to install on the couplers of the twenty cars. 

Undoubtedly, this fundamental awkward incompatibility problem continued into the changeover phase to automatic couplers as the well-established working practice of the pure link and pin era.

    Note the vertical hole and horizontal slot in the knuckle.

It took a very long time, with several extensions which were granted with increasing exasperation.  A very similar thing was observed with implementation of the Westinghouse brake.

If you have the time, the best way to 'follow' the answer to your question is to find, and download, the Google Books or archive.org PDF copies of contemporary publications like Railway and Locomotive Engineering.  These cover both the legislative and operational issues associated with the changeovers.  (They also represent in many cases a good way to waste many an idle hour, and no few non-idle ones!)

I don't know other than I have seen couplers with a slot in the knuckle where a pin could be placed that would allow some mingling.

The Janney coupler was required by the Safety Appliance Act of 1893 to be installed by 1900.

The transition from the "link & pin" to the Janney coupler
Posted by Ulrich on Friday, March 15, 2013 10:02 AM

The transition from one coupler type to another must have caused some operational problems for railroads... for some time couplers of both types must have been in use as railroads made the conversion. How did crews deal with coupling cars that had non compatible couplers?  Given that the 1870s were a tough time economically, how long did it take to  change over to the Janney?
