For some reason I've always been fascinated with older model chucks, the Jacobs chucks in particular. Anytime I've seen a deal, I've picked them up even though I didn't need them. I'm curious to learn more about the history of Jacobs & the different styles they produced & their purpose. I know Jacobs patented his first chuck in 1902, which leads me to more questions. Which style was the first? Are there certain chucks that are more rare than others?
I recently picked up a Jacobs 3A stamped Hartford Connecticut & the patent date of September 16, 1902. I noticed mine has a horizontal line going through the knurling which is different than most of the others I'm seeing online. I'm wandering where this falls in the line of early Jacobs chucks? Is there an online reference that shows the Jacobs chuck line starting with the first? I would like to find out more, so share your pics & information on your Jacobs chucks.
