I suppose it is possible that it could have been used for putting the bend on
one end of a flue tube, however I doubt it.  When you install a flue in a
boiler you use a rolling tool that expands the tube to fit in the sheet.
 Another tool then cuts off the surplus.  

Using a hammer to make the flare on the first end wouldn't give you an uneven
flare unless you were using two dies.  I'm not sure how that first flare is
put on, but I would expect it is on a lathe.

Your machine sounds like a typical oliver, but with such a sketchy
discription it is pretty hard to tell how it was used.

Some more info on that strange tool:
Length is 14 1/2 inches, height 12 1/2 inches, width 3 1/2 inches. 
Hammer head weighs 2 1/2 pounds. Imagine, if you would, facing a cross 
pein hammer that strikes an interchangeable anvil base. Your hand 
grasps a lever that is connected to the hammer by a cam and a tension 
spring. As you pull the handle it causes the cam to release and the 
hammer to strike.

Patent dates are 1907, 1908, 1915 and 1916.
