The first chain saw was patented in New York
in 1858, but it was not until the 1920’s that
chain saws as we know them today began to
appear.
This is a WOLF electric machine introduced
in 1920. As can be seen from the inset the
chain used at this time was a ‘scratcher’ type2.
based upon hand saw designs

3.

The early saws were very heavy, difficult to handle and somewhat unreliable.
Diaphragm carburetors were not available at this time and the guide bar had to be
rotated to keep the fuel tank above the carburetor.3.

4.

All of the early saws used a ‘scratcher’ type chain based on the cutting
principles of hand saws

These “scratcher” chains were very inefficient, did not clear chips, had poor stay
sharp and were difficult to sharpen5.

Joe realised if he could duplicate the larva’s alternating C-shaped jaws in steel, it
just might work. He went to work in the basement of his Portland OREGON®
home and came up with a revolutionary new saw chain.

The Patent filed by Joe Cox in 1948.
The basic design of Joe’s original
chain is still widely used today and
represents one of the biggest
influences in the history of timber
harvesting
