April 23rd, 2012:
I had another one of my hydro twilight zone moments this past weekend. On Wednesday, Davis and I went to the Slater Museum to work on their intake structure. On the way there, we stopped in at Charlie Rosenfield's site at Pawtucket Falls. This is the site with the two Voest Alpine Kaplan turbines with the open hubs. The tailwater is tidal and the salt water wrought havoc on the blade operating mechanism. Charlie leases the powerhouse from Blackstone Valley Electric Light and Power. Slater Mill has been allowed to use part of the powerhouse for dead storage. 20 years ago, I purchased a brand new Bradway Turbine. My good friend, Bill Johnson, the well known designer of cross flow turbines, was on the Board of Directors of the Slater Museum. They were doing an exhibit on the history of waterpower. Bill borrowed the Bradway for the exhibit. It ran for several years and the turbine was stored at Pawtucket Falls Station. During the oughts, Mystic Seaport also ran an exhibit on waterpower. Slater Museum loaned my Bradway to Mystic Seaport. They sandblasted and painted it. It sat for 8 years in CT. The exhibit was mothballed and the Bradway Turbine travelled back to dead storage at Pawtucket Falls HEP. I had despaired of ever getting it returned. So, last Wednesday, when I was finally in Charlie's half of the powerhouse, I went to the other side and absconded with my turbine!! It sat until Saturday night in the back of my pickup truck. There was rain coming in that night and I wanted to get the turbine into the house. I took the ramp boards for the snow blower and propped them against the tailgate. I was able to roll the gatecase down the ramp like a barrel and rolled it into the kitchen door. I got all the miscellaneous parts into the living room. The runner was too awkward and heavy to roll down the boards by myself. Maura and Will had attended a rock climbing competition. I needed to wait until they came home to assist me. I went upstairs to the office and checked my e-mail. Charlie Bradway's great grandson contacted me in November of 2008. He had seen my Bradway Turbine sidebar on this site. He wanted to know more about his Great Grandfather's turbine. Interestingly, in 1981, Dave Wright and I purchased the patterns from the Bradway Turbine Works when they sold the contents of the building. I have also visited the Bradway Turbine Works Buildings. So 5 years ago, Paul Bradway and I reminisced about Bradway Turbines. So ratchet forward to Saturday night when I am off loading a very rare Bradway Turbine and I have gone to my office to check my e-mails and I find this message:
So I wrote back to him:
See
attached pictures for total weirdness!!! I took them 5
minutes ago!!
Sincerely,

Bradway turbine gatecase rolled into my kitchen on Saturday night.
Much to my wife's consternation, Bradway progressive gates temporarily stored in my living room

Another view of offloading the Bradway Turbine Runner.
So how weird is it for Charlie Bradway's Great Grand Child to contact me, after 5 years, on the very hour that I am off loading one of his Great Grandfather's turbines? Paul Bradway sent me this wonderful picture of the patent model that Charlie Bradway took to the patent office with his patent application!
