page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
HAGUE, of Great Pearl Street, Spital Fields, in the County of Midlesex, Engi-
neer, send greeting.
WHEREAS His present Majesty King George the Fourth, in and by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-ninth day of January last, for Himself, His heirs and
successors, did give and grant unto me, the said John Hague, my exors,
aditiors, and assigns, His especial licence, full power, sole privilege and autho-
rity, that I, the said John Hague, my exors, adññors, and assigns, and every
of them, by myself and themselves, or by my and their deputy or deputies,
servants or agents, or such others as I, the said John Hague, my exors,
admors, or assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term of years therein
expressed, should and lawfully might make, use, exercise, and vend my
Invention of "AN IMPROVED METHOD OF MAKING METALLIC PIPES, TUBES, OR
CYLINDERS, BY THE APPLICATION AND ARRANGEMENT IN APPARATUS OF CERTAIN
MACHINERY AND MECHANICAL POWERS," within England and Wales, the Town of
Berwick-upon-Tweed, and also in all His Majesty's Colonies and Plantations
abroad; in which said Letters Patent there is contained a proviso obliging
me, the said John Hague, particularly to describe and ascertain the nature of

page_text: my said Invention, and in what manner the same is to be performed, by
an instrument in writing under my hand and scal, and cause the same to be
inrolled in His Majesty's High Court of Chancery within six calendar months
next and immediately after the date of the said recited Letters Patent, as in
and by the same, reference being thereto had, will more fully appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Hague, do hereby declare that the nature of my said Invention, and the
manner in which it is performed, is described and ascertained by the following
explanation thereof, and by the Drawings annexed, and in the references
thereto (that is to say) :-
My Invention consists in an improved method of making melted metals
pass into and through a mould or chamber, in the centre of which is fixed a
piece or core, made of steel, iron, or any other proper material, of a size
required to form the pipe, tube, or cylinder, and which mould or chamber, and
piece or core, must be of sufficient length, that the metal may cool and congeal
in its passage through the mould or chamber, and come out a perfect pipe,
tube, or cylinder; and the method of combining in apparatus, and applying
the requisite powers, chambers, and cores, to produce and form the pipe, tube,
or cylinder, is shewn by the two Figures or Drawings annexed to this my
Specification, marked Figure 1 and Figure 2, and which Figures or Drawings
are upon a scale of one inch and an half to one foot of the machine or
apparatus described.
Figure 1 is a plan of the machine or apparatus, and the use and application
of the several parts are as follow:-Letter A is a trough or pan to receive
and melt the metal, under the end of which, marked B, is a furnace or fire-
place; into this fire is placed, which draws underneath, up through a flue or
chimney at the other end, marked C, the trough or melting pan being made
deep enough near the end C to form a basin, as marked D, D, to receive and
contain a hollow vessel or chamber E, and also sufficient melted metal to sur-
round and enclose it. Under the screw F is an aperture, through which the
melted metal passes into the hollow vessel or chamber E from the basin or
pan D, D. This hollow vessel is a female screw to receive the male screw G,
and the aperture through which the metal flows is fitted with a stopper or plug,
which stopper or plug is forced tight and close by the screw F; the hollow
vessel or chamber E being filled with melted metal, the male screw G is
forced forward by a power applied at H, which forces the metal out through
the mould or chamber I. The metal is chilled or congealed in its passage
through the mould by water, to hold which a box is fitted on the outside, as
marked K, and is thus produced or formed into a proper pipe, tube, or cylinder,

page_text: which is received by and on the windlass or drum, marked L, to which wind-
lass or drum is applied the requisite power, marked O1, to collect or coil such
pipe, tube, or cylinder, when the pipe, tube, or cylinder is made of metal
capable of being coiled. 02 is a pulley, and O 3 a weight to turn the drum
or windlass. To prevent the melted metal from returning through the screw G,
a box or vessel is placed, marked M, which being kept supplied with water,
chills or congeals the metal, and forms a close stoppage or packing. N, N,
are a wheel and pinion for forcing the screw G forward, and O, O, O, are
wheels for reversing the motion of the screw G, and drawing it backwards.
P is a hollow shaft through which the end of the screw G passes on its
motion backward and forward. Q is a screw for regulating the motion of the
windlass or drum to collect and coil the pipe, tube, or cylinder (if made of
metal capable of being coiled as before mentioned) as it is formed. R is a
screw nut to fix the chamber or hollow vessel E to the pan A. S, S, S, S, S, S,
mark the framework made of iron to support and connect the machinery and
apparatus. T, T, is a clutch box made to shift backward and forward from N
to O, by the lever W, for the purpose of reversing the motion of the screw G,
and of stopping the machine.
Figure 2 is a section of Figure 1. A the bottom of the melting pan; B the
flue leading from the furnace; C brickwork to fill up the space between the
sides of the framework W, W, and form the furnace and flue; D, D, the basin
or pan to contain the melted metal surrounding the chamber; E the hollow
vessel, or chamber, or female screw; I the screw to force down the stopper
marked G, to close the aperture or charging hole, marked H, through which
the melted metal flows into the hollow vessel or chamber E from the melting
pan or basin D, D. I, the lever for lifting the stopper G from the aperture H,
to admit the melted metal to pass into the hollow vessel or chamber E. K the
male screw; L, L, the mould or chamber which contains the piece or core,
and which mould or chamber is made separate, and fixed into the hollow vessel
or chamber E, by screwing into it, for the purpose of changing the size, that
pipes, tubes, or cylinders of various dimensions and calibre may be made by
the same machine. M the piece or core which forms the bore of the pipe,
tube, or cylinder; N the pipe, tube, or cylinder as it issues; O the box for
holding the water to cool and assist the congealing of the pipe, tube, or cylin-
der; P the receiving drum or windlass; Q, Q, the box to hold the water as
described in Figure 1, Letter M; R the wheel for forcing the screw; S the
wheels for withdrawing the screw; T, T, the hollow shaft through which the
square end of the screw passes in its motion backward and forward; U, U, the
nut, as described in Figure 1, Letter R; W, W, W, W, W, W, W, the frame-

Y a weight to turn the drum or windlass.
In witness whereof, I, have hereunto set my hand and seal, this twenty-
ninth day July, in the year of our Lord One thousand eight hundred
and twenty-two.
