Steam & Excursion > Whazzit? (12)

What's that do-dad (gizmo? gadget? thing-a-ma-bob?) up there next to the stack?

BTW, anybody know what engine this might be?  I don't know.

Another mystery - I see a Worthington hot water pump above the front drive wheel.  But, where's the feedwater heater?   Could it be that shadow behind the stack (unusual, to say the least)?  Again, I don't know.

It prevents "stress corrosion cracking...."

Larry, I wonder the same myself.  The Rock Island had a #5110, 4-8-4 engine, but this certainly isn't it.  I've never seen such a device as shown.

Just a guess: Possibly a centrifugal steam/oil seperator, as part of the feedwater heater hidden inside the smokebox?

Nope. Thanks for playing.

Well, the smokebox-mounted plumbing gismo is visible in early 1940s(?) photo of Lehigh Valley 5110, but not in the 1932 Baldwin Locomotive Works builder's photo of  Lehigh Valley 5101.  Hmm....

Lehigh Valley 5110, photo and caption from https://www.railarchive.net/randomsteam/lv5110.htm

"From the collection of Doug Leffler comes this unattributed and undated view of Lehigh Valley 4-8-4 No. 5110, final member of its T-1a class. The time period is probably the early 1940s, after the maintenance-intensive tender booster had been removed and disc main drivers had replaced the spoked type. The location is likely around Pittston or Dupont, Pennsylvania, where the LV's "Mountain Cutoff" freight line paralleled the tracks of the Delaware & Hudson (note the D&H herald on the anthracite facility in the background). For specifications of the T-1a class view the comments for No. 5101 preceding. The Lehigh Valley chose to name its 4-8-4s the "Wyoming" type, after Pennsylvania's Wyoming Valley, rather than the usual "Northern" designation. All the LV Wyomings were gone by the end of 1951."

"Lehigh Valley 4-8-4 No. 5101 was selected for this Baldwin Locomotive Works builder's photo of the T-1a class delivered in 1932. Intended for heavy freight service, these locomotives had 70-inch drivers and a boiler pressure of 250 p.s.i., with cylinder dimensions of 27x30 inches. They weighed 413,170 pounds and produced 66,391 pounds of tractive effort. Their grate area measured 88 square feet, and they had 5422 square feet of evaporative heating surface plus 2256 square feet of superheater surface. As built, The T-1a group had an unusual tender trailing-truck booster that added 18,630 pounds of tractive effort. "

Great detective work identifying the locomotive.

OK, DWDebs/2472 answered these two questions.  The builders photo shows the Worthington feedwater heater in its usual position right at the front of the smokebox, and the shadow behind the stack is a Chambers front end throttle.

But, no one has identified the thing right in front of the left side of the stack, yet?   Any takers?

-LD

BTW, the manufacturer of this device claimed that by 1941 there were 59 locomotives equipped, so it was not a "one off" experiment.

Some unknown furnction associated with the Chambers front end throttle?  Looks like piping from that device connects to the mystery object before going back under the shrouding.

Nope.  Not related to the Chambers throttle in any way, shape or manner.

Nope, again.  Sorry.

Hint:  That pipe out the left side (from your viewpoint) of the device will bend upwards and terminate to atmosphere directly in front of the stack.  Does that help?

something to do with a booster exhaust?

No, it is not related to any type of booster engine, but it IS related to exhaust of the primary engine.

Would that thing be the oil-separator from the exhaust of the Worthington hot-water feed pump?

No.

here's a wild guess, exhaust steam condenser?

NYCStL776 Wrote:

No.  It has a Worthington feedwater heater which does that.

Hint.

It could be mounted as shown, 45 degrees to the left front of the stack with its 6" vent pipe to the atmosphere centered in front of the stack, or

Mounted behind the running board stairway in front of the left side piston valve with its vent pipe vertically inside the smokebox to the center in front of the stack.

Does that give you a clue as to it purpose?

Well,,,,,,, it is now after 7:30PM CST. I'm curious just what that damned thing is, and what it is supposed to do, to improve performance.
