This is very similar to the WWII-era Coffman starter for aircraft engines. Rather than springs, the Coffman utilized an explosive cartridge to pressurize a piston in a cylinder and move the spiral gear. The results were similar--a single, hard twist to a pinion gear to get things started. If you want too see a Coffman in action, check out the 1965 movie, Flight of the Phoenix.
thank you very very much for your valuable comment.I am happy and intrigued to know this fact. Yes the starter does work on a bump start principle.i have not seen the movie but now i will.
Very interesting. I would have thought they would have used something like a massive torsion or coil spring. The use of conical springs is neat. It's probably a lot safer to disassemble as well.
yes you are right. these disc springs are ideal for this application as they can be compressed and released several 100 times without wear and tear and are more reliable and safe
Loved your prior film on Coffman starter land and field commander tractors had such a device loved the planes on carrier deck they used to chain them down backwards toward the sea to allegedly get more power !!!
I have had a design for a diesel engine that uses no electricity at all in my mind for years. I have been trying to come up with a starter mechanism that requires no electricity at all to work. I thought of using a pony motor for a starter but decided it was too much complexity for what I had in mind. This would be perfect. My engine design is now complete.
All this stuff is well known so get better at research. It's WILDLY unlikely you've come up with anything new to the industry. Did you not know diesels with no electrical components were and are common? Lister and other stationary engines don't require electric start or anything else. Hand cranks on large flywheels are a common way to start small diesel and petrol engines. Air starters are another option and they recharge off truck air brake compressors permitting manual pumping if required in an emergency. An example of purely mechanical engines are the wildly successful Detroit two-stroke diesels which have been fitted with air starters by many customers. You can't build an all-mechanical fuel control diesel that burns cleanly enough to meet modern emission requirements but you can personally run whatever you like/can get away with in your country.
This is an intriguing design. I like the use of Belleville spring washers. Compact and safe. Minimal moving parts and durability are top concerns in a device like this. It would not be very practical for an automobile, with the engine enclosed. However, for industrial and agricultural use, this would be a game changer for a lot of people. Hunting down the jumper cables so that you can start an auxiliary generator makes little sense.
Just from the standpoint of weight I would agree with you. This starter looks like it might be approaching 20+ pounds. No problem though for a lawn tractor.
you are absolutely right sir. This product is extensively used in agriculture and farming applications. You can visit our website for more details.www.workwellengineering.com/
thank you for your comment sir.. You can visit our website for more details.www.workwellengineering.com/. This is a very old design that has been bought back to life. It has several applications and is a very versatile and practical product which needs no batteries or auxiliary setup.

@@timmyhudson8643 yep Im 59 and I remember the Aussie 2stroke Victa lawnmowers had a model or two with that feature. At least ten years ago an English man put a wind up spring in Am Radios for poorer countries. Lasted something like 20 minutes.
unfortunately smaller versions are not practical and reliable. We did make a smaller prototype but unfortunately it did not work as expected. This is because very small disk springs do not have the capacity to store and dissipate enough energy to start an engine.
@@workwellengineeringindia3469 No buddy, they are not the same principle....yours is a pre-load compression mechanism while the one the guy is talking about is an inertial flywheel mechanism.
The General ORDERED a crank. It is still to be designed for the Army. He was a CRANK. How surprised we are that anyone talked back to him, and today we do not have this feature on our cars.
@@workwellengineeringindia3469 How about using the braking hydraulic system to also wind up the spring. We can have our wives pump the brakes whilst we sit on the passenger side for us.
My simple arse was thinking there was just a beefy version of a wind-up spring in there. Maybe there's more potential energy packed in this setup for the same volume though?
yes you are absolutely right. The disc springs used in a mechanical spring starter achieves 98% flatness when completely wound. It works on a bump start technique. The springs are the most expensive and vital part of this equipment.
Hochinteressant, aber es ist nicht ersichtlich, wie die gespeicherte Energie in den Tellerfedern beim Auslösen auf die Anlasserwelle übertragen wird 👍👍👍👍👍👍 Viele Grüße aus Germany
Bei 00:47 ist es sehr wohl ersichtlich! Wenn das ganze Federpaket komprimiert auf der linken Seite ist, und der Auslöser betätigt wird, dreht sich die Welle, da die Kugeln, die in den Schneckenrillen einerseits und in der Führung andererseits sind, die Drehung erzwingen wenn sich das Federpaket entspannt! war mir bisher auch unbekannt, aber ich ich informiere mich ob ich das beim Innenborder Diesel anwenden kann - scheint mir ein gutes Sicherheitsfeature zu sein!
Vielen Dank für die Erklärung. Du hast Recht. Sie können es auch in Ihrem Borddieselmotor verwenden. Bei Fragen wenden Sie sich bitte an IPU UK. www.ipu.co.uk.
Look up Belleville springs. This has nothing to do with tanks or anything else but itself. It's a slick, unique design of spring starter (it is not an inertia starter).
This is a BS explanation of the working of a spring starter . You don't tell anywhere that the kinetik energy is stored in de disk springs . The wire spring is not going to start an engine en anyway .
😬Schauderhaft? Was ist das für eine Sprache? Bollywutisch? Ich habe das Video angehalten bevor mir schlecht wird. Ich war kurz davor zu🤢 Ich finde es absolut respektlos. Für diese sprachliche Darstellung ganz klar 👎👎👎👎👎
