Does anyone have information on a Ralston Chain Drive conversion to make a T car chassis into Ton Truck?
Dan Wheeler is working on his Chain Drive truck show below. He e-mailed that the chain system was by the Ralston Co.on van ness street San Francisco, CA. I did a seach and found a posting at: http://www.mtfca.com/discus/messages/257047/295056.html?1340257869 where Doug Langevin, of Grants Pass, Ore back in Jun2012 posted:

I own a chain-drive form-a-truck chassis made by Ralston in San Francisco , California . It came from the Harrah`s collection in the `80`s , via Ken Keesee and Mark Mahoney . The builder was somehow related to the Ralston family of Ralston-Purina Mills fame .It was `sposed to be the only survivor , according to The Harrah`s Museum .

I sent a Private Message to Mr Langevin, but he has not posted on the forum under that name since Oct 13, 2012 so that e-mail address may or may not still be valid.
A Google search turned up a photo of a Ralston two-ton trailer Photographed at the Hays Antique Truck Museum, Woodland, Ca. [Photo at: https://www.flickr.com/photos/jacksnell707/2911156053 ] It appears to have a manufacture’s tag on the side of the trailer which may or may not give us additional information.
I checked the back issues of both clubs magazines but I did not find any mention of Ralston chain drive.
Below are some photos of Dan’s truck. It is registered as a 1925 and has Engine # 10437698 which was recorded on the engine log under Sep 8, 1924. Which would be in the 1925 model year range. See the posting and discussion about the engine number at: http://www.mtfca.com/discus/messages/411944/506062.html?1420077723
I'll post the 3rd photo in the next posting.
Note it appears to use a regular Ford rear hub to drive the sprocket which leads me to believe it is a car chassis.
Any information would be greatly appreciated.

What advantages would a chain drive have over a regular old worm gear TT rear end ?
Not to ignore your question but to put it in a different light.
Chain drive truck attachments for passenger chassis such as the Ralston shown above, pre-date the TT truck. For example, I found an article for the Ralston in the 1916 automobile trade journal.

Who knows? Once the TT was introduced in 1918, the demand for chain drive attachments may have gone down.
