A nice find with cooperation of the COX family...this piece of history preserved forever in the museum. Partial history provided by Robert Cox, below in regards of the saw history and prototype.
To Robert Cox:
I have been searching for a photo of Joe Cox or Joseph Buford Cox, developer of the modern chipper cutter tooth in the 1940s and have come up empty handed. Any chance you know if a photo of Mr Cox exists? Is he a relative of your family by chance???????? I know that Leroy was your great uncle (Cox chainsaw) ........Looking also for some old movie footage from the 1940s or 1950s of one of those vintage chainsaws cutting or bucking.
Reply from Rob:
Joe Cox was my great grandfather. The Cox 140 saw you acquired was given to my grandfather by Roy his brother, the letters A.W.Cox stand for Alvin Willard (Dick) as people around the plant knew him. My grandfather designed it and Roy machined it for the application.
As for the Cox boys there were 4 of them Roy, Alvin, Oliver and Robert along with 1 sister Lillian.
I do have a lot of other things that are not produced items by Cox but passions of Roy's like his paintings.
The Cox chainsaw in the museum, has my grandfathers name engraved in it with his id number, will help in authentication of it as it was never sold but it was given to him by Roy himself and also used by Roy at times, In storage for decades,it is not running at the monent but all parts are there and in good condition. The paperwork I have for it is: The illustrated parts list and assembly guide, the instructions for bar and chain installation, Cox service directory, the Oregon saw chain catalogue and maintenance manual and the original picture of the prototype handle.
You should not have to many problems in the restoration, my grandfather drained the gas and oil before storage. With the chainsaw I will be providing all paperwork and service manuals that it came with in their entirety in a1 condition and the original picture of the prototype handle.
I have the original machined prototype handle as my grandfather helped in the designing of that portion of the chainsaw. Everyone that would be able to give me any other information on this subject has unfortunately passed away.
These are Cox family shot at my great grandfathers bike shop in placenta on Easter 1920 .
I believe Roy (LEROY)is the oldest to help you identify him and my grandfather A.W.Cox (Alvin Willard /Dick) was the youngest.
Prototype handle for final assembly on the COX chainsaw displayed in the museum.
