Mark Dash said:I actually mocked my wings up with the Lego cylinders that I have. I have the old school ones were they are either open or closed. And a hand pump to go with... But I learned that the wings are just air activated and then once they are opened to the desired setting, a locking pin is put into place. On the front wings I don't know if there would be enough room to make something like that work. The front blades drop down in between the rails to flange out the snow.
Yeah ok Craig so I'm thinking that lego cylinders might actually work - http://www.techno-stuff.com/AirSol.htm
and where then are said pictures? as Rooster might say, if there are no pictures, then you didn’t really do it
I said I mocked it up… Never took any pictures. The Lego pistons have to big of a square bottom to be of any use.

I’m pretending I didn’t see that!!
That rules!
MR, or RMC published an article a hundred years or so ago about using hypodermic syringes and flexible tubing to make an air operated switch “machine.” I believe a company piggybacked the idea and manufactured something similar.
Robert
Problem is you can’t buy hypodermic syringes in NY state without a prescription, damn drug users!!!
I’ll send you all you want, used without needles for cost of mailing. Our dog uses 2 per day for insulin.
Thanks Jon that reminded me that my moms a diabetic and has needles, they are in the mail this morning.
Thanks Craig and Rooster, now I’m starting over building one that will be more prototypical, you both suck

Your welcome… I know it will bite me in the a** when I start my project up again.
Ps. When you are subscribed to the topic the word related to vacuums is visible, but when you look at it on LSC its censored…

Looking forward to your project Mark…we want lots of pictures!
got several people sending various size barrels and plungers for the project, looking at some medicine cabinet hinges to use instead of the wire cob job on the first Jordan. So basically the first one I built will be the one that actually plows and gets beat up, the second one will be a rc version to show off and demonstrate how they worked to people. Currently looking into cheapo rc cars and such to see what servos can be salvaged and if it can be wired into the Hobby King RX with little soldering Figuring to move it like the prototype, 1 servo would be needed to raise and lower the front plow. 1 servo to raise and lower the main wing assembly arms up and down - 2 air cylinders would be needed to move the main plow up down(pivots on hinge) 2 air cylinders would be needed to move the small end plow piece up and down. from what I can tell on the D&H Jordans there is a cylinder under the cab portion and that looks to be the one that actually pushes the wings outward(1 per side) the first Jordan I have done so far does not have these 2 cylinders, they are hidden for the most part and wouldn’t help this model actually plow snow on the line the remaining cylinders would appear to be there functionally to lock the wings in place when a load is pushing against the wings. The cylinders on the current Jordan that I have started therefor wouldn’t need to be air compressed/controlled. If you look closely on the D&H Jordans there is a ratchet type wheel where the outside chamber end and the extension tube comes out. Note also those cylinders are not fully round, they have a grooved piece on the top that the ratchet would bite into to prevent the air cylinders from moving under pressure of pushing a load.
Mark Dash said:That's interesting that the have a locking method. The GN (now BNSF) Snow Dozers use a single pin to lock the wings in place. Looking forward to seeing how this works out. Does it look like the front plow lowers below the head of the rail to clear the flangeway?

Not sure if all of the Standard Model 2-200’s (Air powered cylinders) from Jordan all used this type of locking mechanism. The GN looks like a Model 4-100 Type “J” (Hydraulic powered) The Jordans were custom built for each railroads specs, especially the plates on the wings which gave different ditch patterns
You can see the pin locking holes on the gn plow, however I have yet to find the same type of locking pin on the D&H Jordan. These Jordans were heavily used for ditching work which would require more fine tune movements then “just a snowplow” would?? I cannot find anything other the the Jordans on their MOW roster that would be used for ditching purposes.
Mark, The GN designed the Snow Dozers specifically for snow service, and didn’t use them for anything else. They were also home built in the St. Cloud shops. I would imagine that the Jordan Spreaders would have to be a little more flexible with the side wings since the intended purpose for those is spreading ballast, not snow. Here’s a close up of the GN locking pin.

I know from talking with the MOW crew they hate to use the side wings on the Dozers because they take a while to set up, and then they can’t plow very fast. What is interesting to me is that most MOW equipment uses pneumatic pistons when they have access to a locomotive. When the equipment is stand alone they seem to be hydraulic . I remember dumping side dump ballast cars a couple of times and having to wait quite a while for the main res. to pump up to feed the side dump cars. And then the air would be drained in a manner of seconds when you went to dump.

Humm makes me wonder if the GN Dozer was ever patented… Or if the only records for those are with the rest of the GN records back in St. Paul. Interesting find
Here’s another one for you Mark http://www.google.com/patents?id=e9FnAAAAEBAJ&zoom=4&dq=snow%20removal%20railroad&pg=PA5#v=onepage&q&f=false
I have been talking to a couple people at the Cooperstown & Charlotte Valley RR they have D&H 35056 and got this response
“Hi Mark Brian here yes I am the senior operator of the spreader and i volunteer on the C&CV RR in Milford. go to google and you will find a great website by jim otto all the info on spreaders is there again welcome aboard. when we get back running trains we can have you and a group come down and ride along and operate if you like take care brian”
I should be able to gather enough information on this trip in September to get a better understanding of how the actual D&H Jordans operated
D&H #35053 - is in Buffalo, next time out that way I plan a side trip to see that one also
Cool
