IMPROVEMENT IN GAS-FURNACES AND FORGES.
Specification forming part of Letters Patent No. 120,764, dated November 7, 1871.To all whom it may concern:
Be it known that I, JosEPrr . 14oRIs, of
Houston, in the county of Harris and State of
Texas, have invented a new and useful Improve-
ment in Forges; and I do hereby declare the fol-
lowing to be a full, clear, and exact description of
the same, reference being had to the accompany-
ing drawing making a part of this specification, in
which--
Figure 1 is a longitudinal vertical central see-
tion. Fig. 2 is an end elevation, and Fig. 3 is a
section lengthwise of the hammer apparatus.
This invention. relates to an apparatus in which
the gases from one or more forges, instead of
passing off unconsmuned into the atmosphere, en-
ter a furnace and are burnt therein, thereby fur-
nishing heat for the generation of steam in a boil-
er connected with said furnace, which steam is
used to drive a fan that impels a blast into each
forge, and is also used to propel an engine that
operates a hammer, the'exhanst from the engine
being conducted to the tuyeres of the forges
through pipes in which are placed red-hot iron
plates, which decompose the steam, taking up
the oxygen, and liberating the hydrogen which
is burnt in the forges.
Referring to the drawing, a a are the forges,
of which four might be used with one chimney
as well as two, half on each side of the chimney.
The latter consists of an inner skin, b, and an
outer skin, c, with a water-space, d, between.
Between the forges and a and below.the bottom
of the chimneyisafiurnace, e. Fluesfrunthrough
the opposite sides of the chimney, at the lower
part thereof, to conductthe gases from the duck's-
nest a' into the space within the chimney imme-
diately above the furnace, where they may be
consumed. Flaps g, having triangular ends g',
are hinged to the opposite sides of the chimney
and extend over the duck's-nest a', their func-
tion being to conduct gases from the latter to the
flues f. Pipes i connect the water-spaces at the
sides and ends of the chimney to facilitate the
circulation of water. A pipe, j, leads from a
point near the top of the space d, for the purpose
of conducting therefrom the steam generated
from the water by the heat of the furnace to a
fan-blower situated within a case, k, opposite the
rear end of the furnace, from which case a pipe,
1, extends, the same, at any suitable point be-
neath the furnace, dividing into two branches,V' ', which lead to pipes m that pass vertically
through the forges a, opening at their upper ends
into the duck's-nests a'. The pipes IIl m convey
the blast which fans the fire in the forges. At
their lower ends the pipes m are furnished with
removable receptacles a for the ashes and cinders
of the duck's-nests. The exhaust from the case
k passes up into the chimney, terminating within
the same at a point suitable for promoting the
draught. A pipe, o, leads from a point near the
top of the space d, at the opposite end from the
upper extremity of the pipe j, which pipe divides
into two vertical branches, o' o2, which are con-
nected near their middle points by a cross-pipe,
oI, between which and the upper part of the
branch o' is situated a vertical cylinder, p, with-
in which works a piston whose rod q bears at its
lowest extremity a hammer,r. Between thelower
ends of the pipes o' o is an anvil, s, for the ham-
mer r to strike on. Arms q extend one to each
side of the piston-rod q, and have curved plates
q2 at their outer ends which fit the pipes or o2, so
that the latter serve as guides for the rod q. To
the side of the cylinder p an elbow-lever, pt, is
pivoted, the lower end of which is connected with
an arm, t', that projects from a cut-off valve, t,
placed at the center of the cross-pipe o03 and at
the lower end of the cylinder p. The other end
of the lever p is jointed to the upper extremity
of a loop, p2, which incloses the arm q' beneath.
The loop p2 has a cross-bar, p3, against which
the arm q strikes when rising under the ac-
tion of steam introduced into the cylinder p from
the space d through the pipes ol o2. This strik-
ing takes place about at the end of the up-
stroke, and turns the valve t, through the medi-
um of the lever p', so as to cut off steam from the
cylinder p. As the piston descends the arm q'
strikes the lower end of the loop p' and causes
the latter to open the valve t so as to admit steam
to the cylinder p. The pipe o is surrounded by
a tube, u, which contains a register extending
across the pipe o, and thus regulates the amount
of steam that passes through said pipe to the
cylinder p. A lever, v, jointed at one extremity
to the inside of the hollow anvil s, at the lower
part of one end thereof, has the inner extremities
of two treadles, s v', jointed to it near its mid-
die, said treadles extending through the opposite
sides of the anvil. That extremity of the lever
r that extends outside the anvil s encircles in
