Compliments of the United States Patent Office and Sodbuster!

while cleaning my motomag II's a week or so ago, I saw the patent # and decided to try and find it online...it didn't work. How'd Sodbuster find it?

You have to type "D" before the numbers 236609 when entering the patent search... "D" stands for design as in 'Design Patent". Also, you have to specify the search dates are prior to 1978.

You can find it by going here: http://patft.uspto.gov/netahtml/PTO/srchnum.htm

nice work!!

Cool stuff!

This looks to be the patent he filed in '82 for the pro-class wheel based on the description....D277,953


Although, it doesn't call pro-class anywhere.

Joe you amaze me! Always diggin' just a little deeper... The "Chopper Dave" Motor-Mag stuff you found was killer too. BTW, I didn't know about that other patent.

More great stuff from the Mayor of Mongoosetown, USA!

Hey Pete, back at ya. You post some thought provoking unearthed stuff that just gets the rest of us digging.

I wonder where Skip got the nickname?

If you simply Google

Patent D236609

www.google.com/patents comes up with a breakdown and history. Crazy, what will they think of next?

You can download a large .PDF of the file as well.

I google'd it. Seriously I did. First I typed patent search the results included a google feature for patent searches and I found it there. simply listed as "best available copy." Which as you can see stamped at the top of the page. simple as that.

Not to change the subject.....

These look like the Rokon style wheels, Pete.....D232431

It's pretty cool looking at this stuff. I found Lester, Barris, Morris and other old school wheels. Who's gonna find the Webco patent?.....didn't they come from an earlier design.....Barris maybe? They may not be listed under Webco.

Redline cranks.....4358967

That's the right one 76. Nice grab. The August 20, 1974 Patent (D232431) you pulled is surely the predecessor to the Motomag. They were called "Tabloc" Snowflake Mags but commonly referred to as "Kimtab" Mags named after the designer/Patent holder; David Kimball.

While reading the fine print for the Patent granted to Skip, I saw that he listed two picture references to Cycle World Magazine. Specifically, the October 1971 Issue. I began to research that issue and luckily I was able to find a copy. What did I find in terms of that reference? Well, there they were again: What Reilley and then myself et al, had mistakenly referred to as "Rokon" mags. The same mags we had originally debated over, regarding their dates of origin vs. the Motomag.



Sold as the "Tabloc" Snowflake Magnesium Mag. (again more commonly referred to as "Kimtab" mags in the motorcycle world) they seam to be quite coveted by motorcycle builders/collectors much like original MM1's are for BMX'rs.

They came out in 1970 and started appearing on different street bikes throughout 1971. Eventually they found their way into MX on the "Rokon" bikes among others. Without Skip ever seeing these "Tabloc" or "Kimtab" mags, the Motomag may never have come into existence.



I find it very interesting that the whole evolution of the "Motorcycle Mag - turned into - BMX Mag Process" has now come full circle.

In the pictures 76 first posted a while back, we can see this evolution from people like "Chopper Dave" who has now copied the ornamental design of the Motomag to make his own "Motor Mag" for his custom motorcycles.
