The shafts are supplied with oil by inverted glass bowls that supply a days worth of oil, you need to fill them up every morning after they leak out overnight.

They were known as Louvain bottles. They plugged into the bearing block with a cork and had a soft iron needle in contact with the shaft which fed oil as it jiggled. Very messy but effective. I remember them well. I refilled hundreds of them as an apprentice. Yes, they leaked.

The ones we had on the overhead shafting, known as plummer blocks, had bronze bushes in them with a cut away section on the top half of the bearing. There was a metal ring bigger than the shaft but able to rest on it. When the shaft turned the metal ring would start to turn with shaft and pick up oil from the sump of the plummer block and dribble it onto the shaft. They just needed oil adding occasionally, as it would eventually find its way out.

Electro-mechanical single point automatic lubricator SKF TLMR

The modern version of the last few posts, would be the automatic grease cartridges, I thought they were spring powered, but seem to work on battery or a low voltage supply.

Kelly's were 1000 times better!
The things I did and got away with on 72's and 82's you could only outdo with a Bitzer.

About 15 years ago a customer ran out of money on a new installation and had a couple of old 82's.
I had them recoed, put the biggest motor pulley on I could fit so they were at maximum speed running on R404A, POE oil, one @ -4* SST!!!
The capacity charts I had were for R12/22/502 and 404 medium temp would've been so far off the chart it was nuts, so I worked out a correction factor from 502 to 404 and extrapolated out the capacity anyway.
He needed them to work for three years just to get his cashflow going. It was a big pet food abattoir and I can't remember how many tonnes hot/day, I think 11,000kg @ body temp? so a big load.
Both units lasted exactly three years!
I replaced the MT unit with a big Lu-Ve/Maneurop condensing unit, and the LT system with a Bitzer IS.

So Rick, despite popular opinion, you just ain't a pretty face then?


You lost me at "About 15 years.....".

Ring oilers. Quite common in the days of overhead shafting. All these gadgets were quite messy with leaking and spilt oil. Which oil attracted all the dust and soot from the industrial operations carried out beneath and dripped onto the machine operators.

Not to mention also being a Fire Hazard.

Did heaps of work on those H,K,Y and T Kelvies over the years,they were bloody good gear.

But they do seem to dislike R22.

After the phase out of 12 and 502,we converted quite a few to R134a,and R408a,but I can’t remember any on R404a.


We also used to run them in trawlers,driven by the old CAT3208.

I actually found an old Kelly service catalogue in the office,with all the flywheel nut torques,and a bit of other info,the other day.

Blimey Paul, torques? Never realised they were ever that posh. Just a tighten up to a comfortable setting was all we ever did. None fell off that I can recall.

Maybe you got the copy that was meant for us?
