It looks like an ancient one-banger air compressor.

An old hit-and-miss engine.

On the left there is a flywheel,on the right there is a loose pulley & tight pulley. What is in the middle is confusing,is it a compressor,shock absorber or single cylinder engine?. Why no connections are shown on the middle one?.

USBPORT is correct. It is a "hit-or-miss" gas engine.

According to the contributor of the image, it is a belt-driven compressor.

I'll go with the first reply--an air compressor likely made to be driven by a belt from an overhead line shaft. I can't explain 2 pulleys on the right end.

All the hit-n-miss engines I have seen are "hopper" engines with a reservoir of water for cooling. The cooling fins on the cylinder are typical of air compressors.

The one pulley runs the compressor the other one is a idler pulley where you put the drive belt when you don't want to run the compressor.Most things that were run by a lineshaft had the two pulleys for this purpose
