Kept the solids (carbon in the exhaust) from blowing back in the stack and getting reheated and becoming bigger glowing pieces. Aided airflow more than being a spark arrester. MoPac did something similar.
It's usually the bigger glowing embers that stayed hot enough to start a fire. (several Santa Fe ASDE's explained it this way)
ASDE=riding mechanic/ Assistant Supervisor Diesel Engines
I have seen them on any number of ATSF units of that period...I would have to say they were almost standard equipment for ATSF of that era on engined t\hat did not have turbochargers attached to the exhaust.
CSSHEGEWISCH Don has it right, they are spark arrestors, but they look like something cobbled together by Cleburne shop.

Never too old to have a happy childhood!
A not very effective spark arrester.

They look like they could be spark arresters.
