Olaus "O.C." Wold's 1917 Patent

(Click on the picture below to see the full size patent drawing. I've cleaned them up and converted them to the .GIF format. WARNING, they are 80kb+ files and are a slow download but worth it. Opens in a new window!)

In 1917 Olaus Wold patented this double action airbrush that uses a trigger that travels up and down to control both the air and the paint. When the trigger is depressed you first get air and then paint. The farther you depress, the more paint you get. It's a nifty idea but in practice you don't have the control of the "traditional" double action airbrush.

If anyone would like copies of any of the patents on the site, e-mail me and I'll gladly send them to you. The files are small in kb size (346kb for the 5 pages of the Peeler patent) but they are physically large (290" x 426") and they are in .TIF format. That means you'll need a viewer that can open .TIF's and resize them. No problem, Irfan View to the rescue. Click on one of the buttons below to go and download it. Its free (although he'd appreciate a postcard) and is the best viewer around. It also plays audio!
