Casey-Cavin Power Reverse Gear

The Alberta RR Museum’s xCN1392 (xCNoR1392, blt 08/1913) will be celebrating her 100th birthday in 2013. Through this winter, we are preparing her for operation and during the over-haul of the reverser, some well worn parts made their presence apparent and replacements parts need to be manufactured.
Looking to attain some technical information and/or drawings on the Casey-Cavin power reverse gear used on some h-6-g 10 wheelers. Specifically the air chamber of the floating lever circuit.
Have tried looking through web based archival collections (including ours) but to no avail. Lots of information on Franklin and Alco units but these CLC units are quite elusive.
Any direction or help would be appreciated and will assist in rolling her out of the shop in April under her own power.

I found the Canadian patent for this, CA 157481, but unfortunately they don't have image content of patents before 1920 available on line. Perhaps you should contact the patent office and see if they have it in their archives. There should be very detailed drawings associated with a patent.

Here's the link to the Canadian Intellectual Property Office and the information I did find on the actual patent. http://brevets-patents.ic.gc.ca/opi...vin+&start=1&num=50&type=basic_search#Details

I tried several searches at the US Patent office but couldn't find anything there, but could have missed something. Here's the US link. http://patft.uspto.gov/

Good luck!
