Photo: Blocking For Gear Dive Load

A photo from the Wisconsin Historical Society:

https://www.wisconsinhistory.org/Records/Image/IM50499

Description:

“Mill drive purchased by Allis Chalmers and used by Duval. Original Falk caption reads, "260 inch x 34 inch single helical split ring gear... part of a photo a slide series to show ring gear manufacturing.”

Flatcar is unidentified and date is a bit beyond our group but the blocking is of interest.

Because of the words in the caption: "Mill drive", "used by Duval", and the given dimensions of the gear, along with "single helical split ring gear", it is possible that this pair of ring gear halves was bound for the Duval Copper mine in Battle Mountain, Nevada.  This would be the two halves of the gear drive for a 20' ball (grinding) mill in the Duval copper concentrator.

Battle Mountain is located along the UP, so there would be some interchange of the flatcar and load somewhere.

True today, but of course in the period of this list it was the SP.

Correction: Battle Mountain was on the Southern Pacific and Western Pacific in those years. UP was hundreds of miles away.
