the fuel through a bent tuyere or pipe, in which the upper part of the fan

under the hearth and at the back end of the forge, and lead the blast up into
the fuel through a bent tuyere or pipe in which the upper part of the fan

of a portable forge fitted according to my Invention. a is the fan set beneath
the hearth 6 of the forge; c is the bent pipe or tuyere, extending upwards as
shewn, for guiding the blast to the hearth. The tuyere is carried through a
cistern containing water, whereby it is kept cool, as shewn in the detached
view, Figure 2. Quick rotary motion is communicated to the fan a,
through a strap d, passing round a wheel e, which is on a shaft carrying a
pulley f, free to revolve in bearings in the frame g of the forge; h is another
strap passing round the pulley f and a wheel i above, rotary motion being
communicated to it through a handle k, or otherwise; is a chest for holding
tools placed and secured within the frame.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim as my "Improve-
ments in Portable Forges,"
