PATENT WARS: THE CUSHION FRAME

 

The Cushion Frame was patented in 1899 by Charles Travis, and subsequently owned by Colonel Albert Pope of Columbia.

Colonel Pope owned the patent on the conventional ‘cushion frame’ design, which was introduced in 1900 by Barnes Cycle Co.

Iver Johnson introduced a conventional ‘cushion frame’ model (above) only after the patent expired on the cushion frame after 17 years.

The most popular method for cushion frame rear suspension, employed by the Barnes Cycle Co, below, used a single ‘shock-absorber’ between the top of the seat tube and the rear stays. Colonel Pope obtained the Barnes patent after absorbing the latter company into the American Bicycle Co, and introduced it on Columbia bicycles in 1902 with the Model 86 Men’s Cushion Frame and Model 87 Women’s Cushion Frame.

There were two dominant styles of ‘cushion frame’ incorporating suspension on the rear stays. The patent above, filed by James Sager and George Green in 1902, involved two rear stays. I’ve not had a bike with this style of rear suspension, but you can see an example (below) on an Iver Johnson that was owned by my friend Tyler in Colorado.
