This is a true story!
“It Boils Water For A Bath!”
In November 1986, the members of The New England Antique Machinery Club, of which I was the Secretary, received a letter from the Secretary of the Dorrigo Show Society asking if we would be so kind as to put on a display of antique farm engines and tractors at their Dorrigo Showground for the entertainment of general public.
We were delighted at the request as this is what our members do; we go along to show’s and display our old gear, which has a great deal of "historical significance," with some of the items dating back over a hundred years! The engine I was to put on display was almost 90 years old!
Well, the members and I assembled and we left Armidale at around 6.30am and arrived in Dorrigo at around 9.30am. We were shown to an area that the Show Society had set aside for us under an expansive new iron roof supported by 6 large wooden poles. As the gates opened at 10.00am, we were keen to set up before the public started drifting in.
We proceeded to set up our various items of antique “junk” in the spots that each member had chosen.
There was quite a collection of stationary farm engines, oil lamps, steam engines, an impressive steam marine engine, a collection of boat and plane propellers from before WW1, a working model of a steam sawmill that was very detailed and beautifully made, a couple of “drag saws,” set up to cut a large log when the crowd got big enough, Gary's faithfully restored "Lanz Bulldog" tractor, Noel's collection of very rare and beautifully restored antique chainsaws as well as Harry and Isabel’s display of antique household Bric-a-Brac and many other interesting items.
When we had completed our set-up and put all the safety fencing in place, the public started drifting past looking quizzically at each display, stopping every now and then to ask a question of the member who owned the particular piece of gear.
As it was very cool in Dorrigo at this time of the year we decided that a warming cup of tea was needed. So, we busied ourselves filling cups and mugs with tea and coffee poured from all types of “Thermos” flasks. We then settled back to enjoy our smoko.
Suddenly I noticed a man standing about 10 feet away, looking at my "Lister Junior" engine, which was running at the time, with what appeared to be a keen interest. I thought about approaching the fellow, to ask if I could help him. I was enjoying my cuppa very much so I decided to stay put for a bit and just keep an eye on this bloke. The man walked around my engine a couple of times, never taking his eyes of it for a second. I could see that he was puzzled by something because every now and then his brow would furrow and he would gently shake his head from side to side. Suddenly, he dipped his hand into the “hopper,” testing the temperature of the water that was just beginning to make some steam that rose in little puffs from the open top.
As these machines can be very dangerous with spinning "flywheels," exposed gears, very hot exposed exhaust pipes etc I thought I had better go over and approach the man to find out what he obviously didn't understand and keep him at a safe distance from the machine!
“Good Morning,” said I. “Good Morning,” he replied. “Can I be of any assistance?” I asked. The man looked up at me with a deadly serious demeanour. “It’s a hell of a way to boil water for a bath” he exclaimed!
“Oh, no, no, no,” I said, “ this is a farm engine, for a shearing shed,” I explained. It's not for boiling bath water!
“For a shearing shed?” he replied, “what do you mean?” he asked with a weird look on his face. “Well,” says I, “you see, this is an engine that was used to drive an overhead shearing set-up!” “It ran three stands, meaning that each stand had a Shearer, with a handpiece that was being driven by the engine, via a belt connected to the belt pulley on the side of the engine.” As I explained I motioned and gestured toward the various parts so that he would have a clearer understanding!
“But what is the hot water for!” he blurted. “Well the water is for cooling the engine!” I replied. “But how does it cool the engine if it’s hot”, he asked. “ Well, you see, the water doesn't get very hot because of the size and surface area of the tank on the front!” I pointed out to the fellow how the water entered through the engine at the bottom inlet, then, as the hot engine cylinder came into contact with the water, the water became heated. Then through the action of “Thermo syphoning”, the hot water rose up through the top outlet and entered the cooling tank, where it would dissipate the heat. The cooler water would then sink to the bottom of the tank to start the cycle again. Throughout the whole explanation, the man listened very attentively to what I said, without interruption, making sure that he saw everything I pointed out, as I moved my hands to each part I was describing.
After almost an hour of explanation the man seemed to comprehend then how the machine actually worked!
“Well! He said. That makes sense now that you have explained it!” “I thought initially that the machine was used to boil water for a bath!”
“Well you know what it does now, don’t you!” said I. “Well I’m from the city!” he retorted, “I’ve never seen anything like this before!”
Just then, another man approached us and stood beside him. He was obviously an acquaintance of the first man. “What does it do?” asked the second man. Without any hesitation, the first man replied, “IT BOILS WATER FOR A BATH!”
