Dave here: Nate shared this video of him heading out in the snow to do some maintenance. It looks like that rig is running great and moves really well over the snow. Thanks for taking the time to record it Nate!

The other day Nate forwarded me the following images of a Willys home power plant, built by both “Willys Light” and the “Electric Auto-Lite Corporation”. Not knowing much about any of this (and not having the time to source original info from newspapers of the time), I took a break from house painting to venture down internet rabbit holes. What follows is more of a work-in-progress than a finished piece. Hopefully, folks can add or correct the following.
Let’s start with the pics that Nate sent:
Early Automatic Hubs
Dave here: Seth and Roger both shared links to his Facebook post showing a Cutlas Automatic Hub, which is a rarity to see in the wild. That got me thinking that I’d never done a post about the different, early attempts at creating auto-engaging hubs, which appeared to generally be a failure (none ever caught on).
WARN INDUSTRIES Mid 1950s:
I believe the first commercial attempt at an automatic hub was Warn’s hub by that very name, the Warn Automatic hub. This hub appeared as early as 1954 in this brochure (from this post), Willys Motors was promoting the hub as of October of 1954.
Hugo Vidal, through his Brazilian company, AVM, also produced the Automatic Model, an example shown below (from this post):
According to Hugo, the technology was never perfected and customers had problems, so eventually the hubs were pulled from the market.
THOR AUTOMOTIVE early-mid 1960s:
The next production hub with claims to being automatic was the Thor Industries Automatic hub, advertising for which appeared in the early-mid 1960s in Four Wheeler Magazine. While the company’s Electro Hub was sort of automatic, in that you could electrically engage it from the dash, the compass Automatic Hub claimed to be fully automatic. Over the years I’ve seen a few of these, but again this hub didn’t become popular, though I don’t have any reports as to why.
This Thor ad appeared in the July 1963 issue of Four Wheeler Magazine (front this post):
Here is an example of the hub. Allstate also private labeled this hub, as can be seen at the top of this post.
CUTLAS ENGINEERING early-mid 1970s:
Around 1960, Cutlas advertised an “Automatic” hub, but it wasn’t actually an automatic hub, but rather it had ‘automatic axle positioning’, which I believe meant that it made engaging the axles easier (so don’t be fooled by this advertising)!
