(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!)

The fourth Airbrush! In January, 1885, Walkup is granted a patent for an upgraded airbrush with two main improvements. First, the mechanism that pinches the rubber tubing to regulate the air flow at the rear is simplified and moved inside body. Second, the air blast tube can now be adjusted so as to maintain proper alignment with the needle.

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!
