Ed Lingenfelter's Drawings

[Steve DeGaetano]

Hey Preston! Hope you're doing well, buddy. Sorry I took so long to reply!

I've got to find the disk that has the large scans on it, and get it to Steve (I've got too many disks floating around. I should spend some time to organize them. Maybe this weekend). It's just that I've been so busy with work, volunteering on the railroad, cub scout projects, family. I'll get to them soon, I promise!

I think your frame drawings look great!

Preston: Are you superimposing a rotated view here? Or is there a wedge-shaped shim along the slanted side of the driver bearing?

[Steve DeGaetano]

Yes, there are shoes and wedges used to make sure the axles are perfectly parallel to each other and square in the frame. The wedges allow for very fine adjustment.

Hey Steve, no worries! Have fun with your kids and real trains

The frame is drawn from an example in "Modern Locomotive" from a similarly sized engine.

Yes, the slant is there to ensure a "snug" fit. As Steve said there are wedges that are used to fit the axle box:



Although in looking closer at the original drawing, looks like the real frame is much more "square", with tighter fillets and near vertical "slant" on the rear leg.

I can understand the single side adjustment for smooth sliding of the journal, but how do you adjust the axle position with it?

"...the male casting which is fastened to the smoke box, between the cylinders, and in the center of the boiler..."

Oh, that part. If we were playing Fact or Crap, I'd say crap.

Just because YOU don't know what is being discussed, doesn't mean no one knows.

We're discussing driver axle journal bearing mounts to the locomotive frame, with particular emphasis on adjustments to assure the spacing and parallelism of said driver axles, and/or possible journal slide optimization, are we not?
