Basically the precursor of a modern chop saw, they were sold in the 50s as a single item workshop. It can also be used for ripping (not that you'd ever want to) amongst other things. Some people swear by them but I personally don't like them, they can however be useful if you build them into a bench for cutting repeated set lengths at 90 degrees.
This video explains some of their pros and cons better than I can:
Love a radial arm saw, there's one in a workshop where I often work - bit mental as it's set up as a dedicated 90 deg crosscut, but having a long bench and stops makes so many jobs quicker.
Not sure I'd put one in my own workshop - but they definitely have a place.
It's a radial arm saw.

Personally I'd buy a cheap chop saw and spend the time setting it up and buy a really good blade for it (Freud are my preference).
