Brian,Here's one for you, I went on a 196 mile round trip today to pick up a Major radiator (complete with shutters, just what I wanted) after winning the bid on ebay. Met Tim the seller very nice welcoming chap, we saw some of the tractors he was currently working on, in the corner of the tractor shed was an early Diesel Major, looked very original and tidy but for the starting handle which was located on the left hand side of the engine where the starter is usually located?? Tim gave us a demonstration and boy was it hard work turning that handle, or so it seemed!!it sounded just like one of those wartime alert sirens that needed turning with a handle to warn the community of approaching enemy aircraft, then with a quick flip of a lever located on what seemed to be the gearing housing and the Major burst into life and ran as sweet as anything. I have never seen one of those before, was it an original Fordson patent, Tim seemed to think that it was fitted on some export models, I'm just sorry that I did not have my camera with me at the time. I would be grateful of your comments. Regards, Barry IP: Logged |

Yes thats the inertia starter. Think it was made by Lucas. it was fitted to a lot of engines even the Rolls Royce Merlin! Now there was an engine to hand crank to start but thats what they did in desert conditions. I've seen it used on Nuffield and David Brown tractors. ------------------
Kind regards

Hi Guys,These inertia starters...
Basically a big clockwork spring then, flick the lever which releases the ratchet. And they try to claim the wind up radio was a new idea! Interested? There's one for sale, 'brand new old stock' in this months Tractor and Machinery. Regards,

Actually they work a little different than a big spring. They more resemble those little toy cars that you would push on the floor then let go.
These units have a HIGH speed small flywheel that can reach as much as 60,000 RPMs. Basically the crank type 1 either have a bell or an indicator to signal the correct speed, they contain a stack clutch similar to a motor cycle clutch. When cranking is discontinued there is a handle,ring, or lever that is pulled to engage the clutch. The screeching noise you hear is the clutch slipping. The siren like sound is the high speed flywheel turning.
The kinetic energy built up in the high speed fly wheel is what spins the gears over.
These type of starters have been in use since the 1920s on aircraft by all countries. Most of the really big IC aircraft engines are started with these only they are powered by an electric motor, some of which may also be hand cranked if needed. The fighters that had the Rolls Merlin more than likely either had no battery or one so small as to provide only enough output to supply radios and lites. They wanted to put more ammo bombs and bullets in these planes not battery dead weight. quote:

Hi Guys,
The Inertia Starter used on the New Major Fordson was manufactured by Simms Electrics of London. It was advertised as being suitable for tropical countries where battery life was short as well as for use in refineries and coal mining. Fordsons fitted with this starter generally had no lighting system or battery and generator. (Spark free)

Guys,
I found a picture of that Inertia Starter in the club magazine of the "Ford and Fordson Association" issue 12. I hope not getting any CR-problems to make a picture of it to post it here.
