IMPROVEMENTS IN SECURING THE TYRES OF RAILWAY CARRIAGE AND ENGINE WHEELS
Year: 1859

page_text: LETTERS PATENT to William Brookes, 73, Chancery Lane, in the County
of Middlesex, Patent Agent, for the Invention of "IMPROVEMENTS IN
SECURING THE TYRES OF RAILWAY CARRIAGE AND ENGINE WHEELS."-A com-
munication from abroad by Robert Stothert Kirkpatrick, of Brussels, in
the Kingdom of Belgium, Civil Engineer.
PROVISIONAL SPECIFICATION left by the said William Brookes at the
Office of the Commissioners of Patents, with his Petition, on the
7th October 1859.
I, WILLIAM BROOKES, of 73, Chancery Lane, in the County of Middlesex,.
Patent Agent, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN SECURING THE TYRES OF RAILWAY CARRIAGE AND ENGINE WHEELS,"
communicated to me from abroad by Robert Stothert Kirkpatrick, of Brussels,.
in the Kingdom of Belgium, Civil Engineer, to be as follows:-
The improvements consist in forming the spoke ring of the wheel of the
form shown in the Diagram, Figure 1, and the tyre of the form shown in
Figure 2; Figure 3 shows the spoke ring secured to the tyre. The spoke
ring is wedge-shaped in section, and the tyre is formed so as to receive the
spoke ring at A, while the part B, which is rolled flat to allow of the spoke ring

page_text: being put into place, is afterwards made hot and bent into place, as shown in
Figure 3. By this plan, should the tyre break into several pieces, it could
not escape from the spoke ring; and again, as no bolts or nuts are required to
the tume the tune would wear more evenly and last longer.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Brookes in the Great Seal Patent Office on the
5th April 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
BROOKES, of 73, Chancery Lane, in the County of Middlesex, Patent Agent,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventh day of October, in the year of our Lord
One thousand eight hundred and fifty-nine, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Brookes, Her special licence that I, the said William
Brookes, my executors, administrators, and assigns, or such others as I,
the said William Brookes, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN SECURING THE TYRES OF RAILWAY CARRIAGE AND ENGINE WHEELS,"
communicated to me from abroad by Robert Stothert Kirkpatrick, of Brussels,
in the Kingdom of Belgium, Civil Engineer, upon the condition (amongst
others) that I, the said William Brookes, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands and
seals, should particularly describe and ascertain the nature of the said In-
vention, and in what manner the same was to be performed, and cause the
same to be filed in the Great Seal Patent Office within six calendar months
next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said William Brookes, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
The improvements in securing the tyres of railway carriage and engine
wheels, relate to the form of the connecting part of the tyre of a railway wheel
"

page_text: with and of the corresponding part of the spoke rim, or other rim of the wheel
to which such tyre is affixed, and consist, first, in forming the spoke ring of
railway wheels of the wedge-like section shown in Figure 3, and rolled or
turned to the correct diameter. They may be used either with spokes or solid
centres, or with wood fillings, as in Mansel's wheel.
Secondly, in forming the tyres of railway wheels of the section shown in
Figure 1, then turning out the triangular part of section shown by the dotted
line at a, the inside of tyre being turned or rolled to the correct diameter for
shrinking on the tyre to the spoke frame. The projecting part b, Figure 1, is
left level with the inside surface of tyre, to allow of the spoke ring being put
into place, and is turned over into position, as shown in Figure 2, at c. To
facilitate this turning over, I sometimes slit the projection 6 at intervals all
round, and them hammer or press the projecting part, while at a red heat, into
position, as shown in Figure 2 at c, or the tyre being made sufficiently hot
when the spoke ring is put into position, the projecting part 6 is pressed into
place by a suitable die and press. In other respects the new wheel is similar
to those in use.
Having thus described the nature of the said Invention, and the means
adopted in carrying the same into effect, I would have it understood that what
I claim is, the method of securing the tyres of railway carriage and engine
wheels, substantially as herein explained.
In witness whereof, I, the said William Brookes, have hereunto
set my hand and seal, this Fifth day of April, in the year of our
Lord One thousand eight hundred and sixty.
WILLIAM BROOKES. (L.S.)
Witness,
B. J. B. MILLS,
Clerk to the said William Brookes.
