Hancock & other whistle drawings
Author: LocoPilot750

Stumbled into the Atkinson Stanley steamer webpage, and found several drawings of whistles with dimensions. Notice on the top drawing on the right side, it gives dimensions for "extra long" Hancock whistes. I didn't know a longer version was available. (My "Frisco" Hancock is even longer yet) The lower drawing has dimensions for the short bell three chime, with dimensions for the long bell in red. There are other drawings of other locomotive type whistles, and valves.  https://bruceatkinson.com/stanley/whistledrawings.shtml

I've never seen an mention of an extra long bell but here is a short bell Hancock, in a step-top and a flat-top version. By the way, the lever on the long-bell has been cut down. I should be even with the top of the bell. The lever on the flat-top has been bent. I should be pointing straight up.

What RR/engine did the bell with the bent lever come from?
There might be a ‘ mounting orientation’ explanation.
( It reminds me of a PRR whistle...)

Wes,
  I don't recall where that one was from but the Western Pacific seems to have been the largest user of these short-bell Hancocks.

Does anyone here know what the dimensions for a Rock Island 4-8-4 5000 or 5100 series Alco engine was?  I'm thinking these were either Hancock or Nathan whistles.

I always thought Rock Island used Hancocks. Those in the photos look like the flat top version. Hancock replaced those with the step top design in 1938.

My Dad always called the long bell Frisco whistles "Nathans".  Our whistle on 1522 had no markings to tell us who made it.  We also put an IC long bell on it once in a while.  Identical to ours, but didn't sound the same.  Go figure.

The diameter of the bell and the wall thickness is not the same. all of these factors play a role, not just the length of the chambers.

The Frisco made their own whistles, the flat-tops, step-tops and 6-chimes, all made in house. They do look similar to a Hancock though. The flat-top, in the second photo is a Frico bell on one of my bowls.

Wow, that's a big one for sure. You could cut that one up in thirds, and still have some left over.  This IC moaner is the largest one I have in a small collection. The bell is 18-1/2" in length, not counting the top cap.

I can understand the wall thickness and diameter making some differences.  I also realize materials varied between brass/bronze and cast iron/steel.  Just curious...did the brass vs. the cast iron make a notable difference affecting the tone?
You noted Hancock replaced the 'flat top' style with the 'step top' style after 1938.  The Rock Island 5100 series engines were produced by ALCO in 1944 and 1946, but these whistles appear as flat tops.  As new engines, I'd thought these whistles would have been supplied by ALCO, but possibly they were using pre-1938 stock from their warehouse!!?

They might be something other than Hancock whistles, but similar. Or, they could have fitted out new engines on delivery & set up, from a supply of new or reconditioned whistles. Its possible they made their own whistles, and stuck with the flat top design.
