IMPROVEMENTS IN RAILWAY WHEELS AND APPARATUS CONNECTED WITH RAILWAY CARRIAGES
Year: 1847

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
GRAFTON, of Holborn Hill, in the City of London, Engineer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Sixteenth day of
January, in the tenth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Henry Grafton, my exors, adiñiors,
and assigns, Her especial licence, full power, sole privilege and authority,
that I, the said Henry Grafton, my exors, adñiors, and assigns, or such
others as I, the said Henry Grafton, my exors, adññors, 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 "IMPROVEMENTS IN RAILWAY WHEELS AND
APPARATUS CONNECTED WITH RAILWAY CARRIAGES;" in which said Letters Patent
is contained a proviso that I, the said Henry Grafton, shall cause a particular
description of the nature of my said Invention, and in what manner the
same is to be performed, by an instrument in writing under my hand and
seal, to be inrolled in Her said Majesty's High Court of Chancery within six
calendar months next and immediately after the date of the said in part

page_text: tyres e and f. The tyres e and fare set at such a distance apart as will be
suitable for running on the two widths of guage required. Thus, supposing
the two guages of two lines of railway were respectively four feet eight and
a half inches and seven feet, then the inner flanged tyre would be fixed suit-
able for the narrow guage, and and the flanched tyre f could be fixed suitable
for the wide guage. In case it be desired to make wheels according to my.
Invention for other lines of railway of different guage and differing from the
case given, then the wheels will be made accordingly by varying the width of
the cylindrical hoop constituting the felloe of each wheel, so that it may be
suitable for the particular case for which the wheels are to be made. The
breaks I prefer to use in combination with such wheels are similar to those
used with cranes and other machinery, and the means of combining such
breaks with wheels such as are above described will readily be understood on
examining Figure 3, being a break which embraces the wheel, and comes
into the space between the two flanged tyres of the wheel, as is shewn, and
the break is put into action in the following manner:-y is a lever moving on
an axis at a. The break is attached to the lever, as is shown. wis a con-
necting rod which connects the lever y with the lever u, and it is by means
of the lever u that the guard or other person puts on the break, so as
to come in conact with the wheel between the two flanched tyres. When the
lever is released the weight of the parts will cause the break to be at a
distance from the wheel.
Having thus described the nature of my Invention, and the manner in
which the same is be performed, I will state that I do not confine myself to
the details shewn, so long as the peculiar character of my Invention be retained.
But what I claim is,―
First, the manufacture of railway wheels, each having two flanched or
railway tyres, and the adaptation of such wheels to carriages so as to run on
two lines of railway of different guages, as herein described. And,
Secondly, I claim the combining of breaks with wheels of railway carriages,
each wheel having two flanched tyres thereon adapted to run on two different
guages, in such manner that the breaks may act on the surfaces between the
tyres as herein described.
In witness whereof, I, the said Henry Grafton, have hereunto set my
hand and seal, this Sixteenth day of July, in the year of our Lord
One thousand eight hundred and forty-seven.
HENRY (L.S.) GRAFTON.
