Welcome to eWillys.com, a website for vintage jeep enthusiasts. I update this website nearly every day with jeep deals, jeep history, interesting reader projects, jeep related info, and more.
These quick searches can help you find things on eBay. People list in the wrong categories all the time, so don't be surprised to see brochures in the parts area for example.
The links to posts below show jeeps grouped by models, condition, and other ways. Some of these jeeps are for sale and others have been sold. If you are unsure whether a vehicle is still for sale or not, email me at d [at] ewillys.com for more info.
There are plenty of interesting, unusual, historic and surprising stories related to Jeeps and their owners. In addition, some of these features have nothing to do with jeeps. This link will display all featured stories starting from the latest.
Looking for parts and not sure where to go? There are a variety of large and small new and used parts sellers both online and offline.
Importantly, the allure of buying a project jeep can be romantic. The reality of restoring a jeep can be quite different, expensive and overwhelming without the right tools and resources. So, tread carefully when purchasing a "project". If you have any concerns about buying a vintage jeep, or run across a scam, feel free to contact me for help, comments or concerns .

Looks like they were trying to do a live pto. Shaft running through the tranny main shaft connecting to motor crank shaft. That way when you stepped on the clutch the pto would continue to rotate. I wonder if any were built.
Well that’s interesting. I need to take a closer look at the ad. It was the date of the filing that was puzzling me, but your answer may explain that.
I’ll see if I can locate a better/clearer scan of the text. I didn’t realize just how bad the scan and subsequent text translation was.
That would have been a really nice upgrade to the Willys PTO system. As Dave Mn. has mentioned, it would have allowed a “live PTO” function. When using a rear PTO tool such as a bush hog rotary mower on either a Willys setup or a farm tractor, pushing in the clutch would also stop the mower. This could result in un-mowed grass at the end or rows or cuts when the clutch was pushed in to make turns. At about the same time as this patent, farm tractors were transitioning from “non live” to “live” PTO as an extra cost option …….later transitioning to standard equipment. I have had several 1955-1957 Case model 300 tractors from that era……used them for mowing……MUCH prefer the “live” PTO setups.
Neat stuff Dave…….thanks again
Allen,
Thanks for the additional bits of info! That may explain why Willys Motors was looking investigating the tech.

Dave, another great find and worthy of more research. Many of the patents were captured by automatic OCR scanning devices and the quality isn’t always great. As stated, that would have a been an important upgrade.
That would be interesting, but without the “dual Clutch” setup of a tractor I’m not sure how easy it would have been to use.
While some tractors used a dual clutch system ,many did not. I don’t know all of it but it looks like they are using a band brake around a planetary, believe Farmall used something similar. May be wrong just going by my experience.
