CERTAIN IMPROVEMENTS ON WHEELS FOR CARRIAGES
Year: 1837

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN HAGUE,
of Cable Street, Wellclose Square, in the County of Middlesex, Engineer,
send greeting.
WHEREAS His late most Excellent Majesty, King William the Fourth, by
His Letters Patent, under the Great Seal of Great Britain, bearing date at
Westminster, the Tenth day of May, in the seventh year of His reign, did, for
Himself, His heirs, and successors, give and grant unto me, the said John
Hague, His especial licence, full power, sole privilege and authority, that I,
the said John Hague, my exors, adñors, and assigns, or such others as I, the
said John Hague, my exors, adñors, or assigns, should at any time agree
with, and no others, from time to time and at all times during the term of
years therein expressed, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of "CERTAIN IMPROVEMENTS ON WHEELS FOR CARRIAGES," in which
said Letters Patent is contained a proviso that I, the said John Hague, shall
cause a particular description of the nature of my said Invention, and in what
manner the same is to be performed, to be inrolled in His said Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear
NOW KNOW YE, that in compliance with the said proviso, I, the said
John Hague, do hereby declare the nature of my Invention, and the manner
in which the said is to be performed, are fully described and ascertained in and

page_text: as will be hereafter explained.
DESCRIPTION OF THE DRAWING.
Figure 1 represents an edge view in section of a railway carriage whee
constructed according to my Invention; Figure 2 is a side section of Figure 1
and Figure 3 shews the mode of combining the spokes together previously to
casting the nave thereon. The spokes are formed by means of flat bars of
iron, which are either shut or welded together at the point f, or otherwise a
bar of iron of the length of two. spokes may be bended over at the point f
and then the part f is to be forged into a tenon, as is shewn in the Drawing;
the other ends of the spokes are bent in towards each other in such manner that
when the number of which a wheel is to be composed are placed together they
will lie together surface to surface, and in that form will have the cast-iron
nave run on in a similar manner to what has long been practised in casting the
naves of wheels on to ordinary wrought-iron spokes, and is well understood,
though I prefer, that it should be performed as hereafter described. In putting
the parts of this wheel together the tenons of the spokes are first placed in
mortices or holes formed in the ring or felloe g, which in this instance may be
of cast or wrought iron, but I prefer wrought iron. If a cast-iron felloe be
used it is preferable to have it ruu on to the spokes, they being suitably placed
in a mould for that purpose, and the ring or felloe should be cast first and then
the nave is to be cast on when the felloe is cold. By the mode in which the
spokes are formed and their ends which are cast in the nave butting together,
each spoke, when meeting any shock or pressure transmits it to the next spoke,
and the wheel so constructed will be found a highly useful wheel and capable
of enduring the shocks to which railway wheels are subject, or in place of em-
ploying two plates for the spokes four bars may be used joined together at the
point where, they enter the felloe or ring; but the upper ends are to be shaped
like those last described, so that the ends which are cast within the nave be
together and butt against each other, and then come down to a
point at the
part f, as above described, and when laid together touch and assist each other
in supporting shocks..
The second part of my Invention consists in a mode of casting on naves of
wheels to wrought-iron spokes by the application of brass or copper, for the
purpose of making or fixing of the spokes in the cast-iron naves; and in order

page_text: to perform this part of my Invention I prepare the ends or surfaces of the
spokes (or such like instruments which connect 'the nave. with the ring or
felloe) which are to be cast into the nave by first dipping such ends into a
solution of acid, in order to remove the scale or oxide, as commonly practised,
and as is well understood; having made such surfaces clean I dip so much of
the end of the spoke (as is to be contained in the cast-iron nave) in water and
dust borax over the same; when dry, that part of the spoke is to be made red-
hot and immediately dipped into melted brass or melted copper, by which that
part of the spoke will become coated; and when the cast-iron nave is cast
thereon the spokes will be more securely retained therein than when the
spoke without such coating is cast into the nave as is the practice with those
iron wheels now made. And further, in order securely to connect the spokes
or such like instruments with the outer ring or felloe, I place the spokes and
felloe over a fire, and cause borax to melt thereon and run into the joints; and
having done so, I apply brass or copper which is broken very small, and it is
well known that as the same melts it will follow into those places where the
borax has previously gone, by which means I braze the parts together.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I am aware that
variously constructed wheels have been before made of wrought and cast iron.
I do not therefore claim such wheels generally, but only when combined
according to my improvements; and further, I do not claim the coating of
iron with copper or brass when used for other purposes. And I do declare
that what I clain as my Invention is,―
First, the mode of constructing the spokes by bringing plates or bars of
iron to a point at f, where it is connected with the felloe, and producing an
angle up to the nave, and then bending inwards to each other, and when the
number for constituting a wheel are laid together they touch, and lie together
as above described.
Secondly, I claim the coating of the spokes (or such like instruments by
which the nave and felloe are combined) with copper or brass, in order when
the nave is cast thereon the same may be more securely combined with the
spokes.
And further, I claim the brazing the spokes to the ring or felloe.
In witness whereof, I, the said John Hague, have hereunto set my
hand and seal, this Eighth day of November, in the year of our Lord
One thousand eight hundred and thirty-seven.

(L.S.) HAGUE.
