Franklin stove

noun1

1. •
   A metal-lined fireplace with a hollow baffle and a flue acting as an inverted siphon, intended to produce more heat and less smoke than an ordinary open fireplace.

   • The furnishings have a quiet charm: an old Franklin stove and over it an octagonal wall clock, graceful saberleg chairs and a Victorian table, oil lamps converted for electricity. — 1953
