This invention was entered at the Patent Office on the 15th instant,
by James K. Hobbs. The improvement consists in the placing of
grate-bars at the bottom of the fire chamber, below which is an open
air chamber into which the cinders and ashes fall through the grate,
instead of accumulating and clogging the fire chamber. The cinders may
be drawn out of the air chamber by an opening at the side of the
forge. The blast is admitted above the grate, and the mouth of the air
chamber being ordinarily closed, the blast is not affected by the
grate. We think it must prove a useful invention.
