Improvements in or connected with Tuyeres for Smiths' Forges and
the like.
1, WILLIAM MORGAN 31 Reading Street New Swindon Wiltshire Foreman of
Smiths, G.W.R. do hereby declare the nature of this invention to be as follows :—
This invention has for its object the improved construction of tuyeres or forges,
for the purpose of enabling the blast to be heated before entering the fire.
I provide an airtight box of any suitable configuration, having two spaces, one
annular space being at the top or crown the other at the base. The air blast
enters the box, the current then divides, passes round the annular space which
surrounds a hollow centre piece, through which the delivery pipe passes, the currents
then unite and pass through a suitable channel to the lower chamber from which
the blast now issues through the delivery pipe to the fire. By this arrangement it
will be seen that the air or blast is heated during its passage round the centre piece,
the top of the tuyere being thereby kept cooled by its passage and the fire is thus
much hotter owing to the more perfect combustion of the fuel. In the centre
piece aperture, I provide a poker operated by suitable levers by means of which
the fire may be readily cleared when desired. A slide door or trap is provide for
enabling the ashes etc. to be removed from the interior of the apparatus. The
main lever carrying the poker is supported in the chamber carrying the ash door,
this chamber being provided with suitable legs to support same.

I, WILLIAM MORGAN 31 Reading Street, New Swindon, Wiltshire Smith's
Foreman, do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by
the following statement :-
This invention has for its object the improved construction of tuyeres for forges
for the purpose of enabling the blast to be heated before entering the fire.
I provide an airtight box of any suitable configuration having two spaces, one
annular space being at the top or crown the other at the base. The air blast enters
the box, the current then divides, passes round the annular space which surrounds
a hollow centre piece through which the delivery pipe passes, the currents then
unite and pass through a suitable channel to the lower chamber from which the
blast now issues through the delivery pipe to the fire. By this arrangement it
will be seen that the air or blast is heated during its passage round the centre piece,
the top of the tuyere being thereby kept cooled by its passage and the fire is thus
much hotter owing to the more perfect combustion of the fuel. In the centre piece
aperture I provide a poker operated by suitable levers by means of which the fire
may be readily cleared when desired. A slide door or trap is provided for enabling
the ashes etc. to be removed from the interior of the apparatus. The main lever
carrying the poker is supported in the chamber carrying the ash door, this chamber
being provided with suitable legs to support same.

page_text: Referring to the annexed drawings.
Fig. 1 is a sectional side elevation of a forge constructed according to my
invention.
Fig. 2. plan view of same.
a is an airtight box having the space b at the top and the space o at the bottom.
The air blast enters the space b by the port d (Figure 2) divides and passes round
the hollow centre piece è & then by means of the port f. shown in dotted lines
(Figure 2) enters the lower chamber c & passes up the delivery pipe g. to the fire.
In the delivery pipe g. a poker h is pivotted to a lever i which is in turn pivotted
to the casing at ; & operated by the handle k. The poker h is for the purpose of
clearing the fire & delivery pipe g as desired. A sliding door is provided to
enable the ashes to be withdrawn from the chamber c.
It will be seen that the air in its passage through the space b is heated at the
same time cooling the delivery pipe g.
Having now particularly described and ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is,
1. In tuyeres the combined construction and arrangement substantially as shewn
in Figures 1 & 2 of the annexed drawings.
Dated this 12th day of December 1892.
