Browning Automatic (NO not the gun)

Anyone ever run into a Browning Automatic Shifting system? This Part of one came into the CoOp last week....had me scratching my head. Did some research...looks interesting...but fragile! A section of the sprocket hinges over and mates with the adjacent gear to make for smooth shifting transitions. Crazy Stuff!



Here is a link to a webpage on how it works....in theory....

I am searching the bins to see if any other parts of this oddball system came in with this.

Never saw it before. Looks interesting but overengineered and fragile as you said. Those little pins working in a dirty environment probably would wear out fast. Are the splines for a proprietary freehub?

The splines look like they would match up with a Shimano Freehub, but I did not check. Nicely machined....like a big WATCH movement...but I would think that grit, grease and abuse would be a problem.

According to Frank Berto in ​The Dancing Chain, SunTour had the rights to it for awhile, and it was sold as the Suntour BEAST in the early 90's. I'm guessing here, but I'll bet "BEAST" was an acronym for B​​rowning Electric Automatic Shift T-?-?-?

BTW, my first decent lightweight bike was a '74 Browning Grade I. Japanese - I think it was made by Panasonic.

Looks like the Browning Family was still tinkering with the idea in 1996, where it supposedly was banned from Olympic use by the UCI in the 1k race...and yes, it is the same Browning as in BAR, Browning Automatic Rifle, auto shotgun and .45. The Browning system made it to the public market on the 2002 Grisley Metropole....Never heard of it....

Browning also made 2 and 3 speed lock out auto for BMX race bikes in the 80's worked pretty good but didn't sell well because of the high cost about $600 back then. When most nice racer's BMX's sold for $300-400. It was questionable upgrade that sold for more than the bike it went on. The main problem with Brownings weapons grade manufactued autos is they could never get the cost down to something reasonable for a production bike.

I know very little about the BEAST (first time I've used that term), but I've been very intrigued since I first saw mention of it some 25-odd years ago in a Bicycling magazine. I strongly believe you have just published the best photos of the Browning Automatic Shift Transmission. Ever.

I KNEW when I came across it, that is was something ODD, and rare....will have to see if there are any other bits to the system about...so a few quick pics with the iPhone so I could further research when I got home, trying to shoot angles that best showed off the WEIRDNESS of the device.
