PROVISIONAL SPECIFICATION.
An Improvement in Tue-irons for Blast Furnaces.
ROBERT THOMAS HOWARD Master Blacksmith, Mather Street Iron Works,
Farnworth near Bolton JOHN COLLIER, 8 Bolton Road Kearsley, Farnworth,
near Bolton, Overlooker, do hereby declare the nature of this invention to be as
follows:-
Our improvement, consists in constructing the tue-iron in two parts or sections,
by means of chaseing the barrel of tue iron, for a few inches at its extreme end on
the outside and chaseing the nose of tue-iron, for a few inches inside. And the
blast pipe, has upon its connecting point with the nose end of tue iron, a projection
of about two inches, to permitt of a packing-ring to enable the continuation of
blast pipe in the nose of tue iron to form a water tight joint when the two parts
are screwed together.
We also accomplish the same object by means of flange joints, arraigning one of
them at the end of the barrel & the other at the end of the nose of tue-iron
& connecting them by means of bolts or set screws, with a packing ring in-between,
to make a water tight joint.
The blast pipe as in screwed arraignment.
We claim for our improvement the following advantages
Firstly. A saveing of at least 50% in the cost of replaceing a burned tue-iron.
As by our method the nose end "only" of the tue-iron requires replaceing and it
can be replaced, without in the least disturbing, either, the brickwork, barrel of
tue iron, water trough, blast-pipe, or any of the joints belonging thereto.
Secondly. Greater facility in changeing the blast, by attaching, either, long,
short, large, small, or angular, nose ends as the nature & kind of work requires :
and at a minimum cost of time & money.

ROBERT THOMAS HOWARD, Mather Street Iron Works, Farnworth near
Bolton, Master Blacksmith and JOHN COLLIER 8 Bolton Road Kearsley near
Bolton Overlooker, 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 refers to improvements in or relating to tue irons for smiths and
blast furnaces; and consists in constructing the tue iron, in two parts or sections,
by means of chaseing the barrel of the tue iron, for a few inches at its extreme end
on the outside, and chaseing the nose of the tue iron, for a few inches inside.
And the blast pipe has upon its connecting point with the nose end of the tue
irou, a projection of about two inches to permit of a packing ring to enable the
continuation of blast pipe in the nose of the tue iron to form a water-tight joint,
when the two parts are screwed together.

page_text: We also accomplish the same object by means of flange joints, arrangeing one of
them at the end of the barrel, and the other at the end of the nose of tue iron, and
connecting them by means of bolts or setscrews, with a packing ring in between, to
form a watertight joint.
Blast pipe as in screwed arrangement.
We also accomplish the same object by replaceing the ordinary cast iron blast
pipe, with a wrought iron one, in two sections-coupled together by what is known
as a coupling and chased at each end.
We also chase the blast hole of the nose end and connect it directly with the
chased end of the wrought iron blast pipe, we then carry the wrought iron blast
pipe, right through the barrel and water trough, and by means of a nut, washer,
and packing ring at the back of the water trough we secure the nose end of the
tue iron to the barrel. We also insert as in previous arrangements a packing ring
between the barrel and nose end of the tue iron, to form a water tight joint.
DESCRIPTION OF DRAWINGS.
Fig. 1. is a side elevation of a tue iron on our improved principle. Chased
arrangement.
Fig. 2. is a sectional illustration, showing A. the chased end of the barrel B. the
chased end of the nose C. the projection on the blast pipe D.
Fig. 3. is a plan of Fig. 1.
Fig. 4. is a front elevation of Fig. 1.
Fig. 5. is a part elevation, and part section, of flange joint arrangement,
E. flange on the end of the barrel; F. flange on the end of the nose.
Fig. 6. is a part elevation, and part section, of the wrought iron blast pipe
arrangement, D. is the blast pipe, which is in two sections, a, and b.
G. is the coupling to connect the two sections of the blast pipe, H. is the chased
blast hole, of the nose end, into which is inserted section a. of the blast pipe, C. is
a socket joint which permits of a secure attachement of the nose end to the barrel
of the tue iron.
I. in Fig. 1. shows the nut and washer at the back of the water trough.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
In combination with tue irons employed in smiths hearths, and blast furnaces;
the adaptation of detatchable nose ends-
1st. By the chased arrangement.
2nd. By the flange joint ar.angement.
3rd. By the wrought iron blast pipe arrangement substantialy as described in
our statement.
