FURTHER IMPROVEMENTS IN BRAKES FOR RAILWAY CARRIAGES
Year: 1859

page_text: LETTERS PATENT to Jozé Luis, of the British & Foreign Office for
Patents, No. 1B, Welbeck Street, Cavendish Square, in the County of
Middlesex, Patent Agent, for the Invention of "FURTHER IMPROVEMENTS
IN BRAKES FOR RAILWAY CARRIAGES."-A communication from abroad by
Laurent Rigolier, of Rhône, in the Empire of France.
PROVISIONAL SPECIFICATION left by the said Jozé Luis at the Office
of the Commissioners of Patents, with his Petition, on the 17th Sep-
tember 1859.
I, JozÉ LUIs, of the British & Foreign Office for Patents, No. 1B, Welbeck
Street, Cavendish Square, London, in the County of Middlesex Patent Agent,
do hereby declare the nature of the said Invention for "FURTHER IMPROVE-
MENTS IN BRAKES FOR RAILWAY CARRIAGES," & that it has been communicated to
me from abroad by Laurent Rigolier, of Rhône, in the Empire of France, to
be as follows:-
The improvements which I have made in the brake for which I have
already obtained Letters Patent, No. 281, 1859, relate especially to the par-
ticular form of the pieces, and do not in any way prevent its free adaptation on
every kind of railway carriage. The encircling hoops are parallel to the
interior face of the wheel, and are suspended by bands strongly fixed upon the
timber work, and have thus only to yield to the efforts which displace them
laterally according to the requirements of the service, and to prevent the wear

page_text: resulting from repeated friction they are lined with cast-iron segments which
are fixed to their peripheries. The springs which press against the brake are
held two by two by the ends of the tie pieces which support the working
pieces.
To preserve the pressure of the springs, the brake guard turns a
crank placed within his reach, and withdraws a rod by which the four encir-
cling hoops are simultaneously removed. When the working of the crank has
sufficiently removed the brakes, a stop bar, placed on the cross beam of the
carriage, fixes the position of the above-mentioned rod during the movement,
and a recall rod becoming free places itself at the bottom of the groove which
terminates the working rod of the brakes.
If any unforseen obstacle requires a rapid stoppage, the guard raises hastily the
stop bar by means of a lever, and the brakes, yielding to the constant pressure
of the springs, act strongly on the wheels in the whole extent of their large
surface. This apparatus, although constructed for producing a rapid and
immediate stoppage can render equally important services in cases where a
slow and progressive stoppage is required. For this purpose the working
pieces are made to bear the end of the rod (above spoken of) and then on
loosening by degrees the crank, the brakes are gradually brought to bear so as
only to produce a gentle slackening, as is often necessary in the descent of
rapid slopes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Jozé Luis in the Great Seal Patent Office on the 15th
March 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOZE
LUIS, of the British and Foreign Office for Patents, No. 1", Welbeck Street,
Cavendish Square, London, in the County of Middlesex, Patent Agent, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of September, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-second year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Jozé Luis, Her special licence that I, the said Jozé Luis,
my executors, administrators, and assigns, or such others as I, the said
Jozé Luis, 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,

page_text: exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "FURTHER IMPROVE-
MENTS IN BRAKES FOR RAILWAY CARRIAGES," a communication from abroad by
Laurent Rigolier, of Rhône, in the Empire of France, upon the condition
(amongst others) that I, the said Jozé Luis, 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 Inven-
tion, 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 Jozé Luis, do hereby declare the
nature of my 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, and accompanying Drawings, that is to say: -
The improvements which I have made in the brake for which I have
already obtained Letters Patent, No. 281, 1859, relate especially to the par-
ticular form of the pieces, and do not in any way prevent its free adaptation
on every kind of railway carriage.
Figs. 1 & 2 represent end & side views; Fig. 3 a plan. The encircling
hoops A are parallel to the interior face of the wheel, and are suspended by
ties B, strongly fixed upon the timber work, and have thus only to yield to the
efforts which displace them laterally according to the requirements of the ser-
vice, and to prevent the wear resulting from repeated friction. They are
lined with cast-iron segments which are fixed to their peripheries. The springs
which press against the brake are held, two by two, by the ends of the tie
pieces C which support the working pieces; see Drawings, Figs. 1, 2, 3. To
remove the pressure of the springs, the brake guard turns a crank D placed
within his reach, and withdraws a rod E which, by means of the axes F and
the recall rods G, simultaneously removes the four encircling hoops. When
the working of the crank has sufficiently removed the brakes, a stop bar H
placed on the cross beam of the carriage fixes the position of the above-men-
tioned rod E during the movement, and the recall rod K, becoming free,
places itself at the bottom of the groove which terminates the working rod of
the brakes.
If any unforseen obstacle renders a rapid stoppage necessary, the guard
raises hastily the stop bar H by means of a lever L, and the brakes yielding
to the constant pressure of the springs act strongly on the wheels in the whole
extent of their large surface. This apparatus although constructed for pro-
ducing a rapid and immediate stoppage, can render equally important services

page_text: in cases where a slow and progressive stoppage is required. For this purpose
the working pieces K are made to bear the end of the rod (above spoken of)
and then on loosening, by degrees, the crank, the brakes are gradually brought
to bear so as only to produce a gentle slackening, as is often necessary in the
descent of rapid slopes.
Having thus described the nature of the improvements which I have
effected in my new brake for railway carriages, tenders and engines for which
I have already obtained Letters Patent, No. 281, 1859, I wish it to be under-
stood that what I claim and desire to secure by Letters Patent are the
improvements thereunto, as above described and represented in the annexed
Drawings.
In witness whereof, I, the said Jozé Luis, have hereunto set my hand
and seal, this 15th day of March, in the year of our Lord, One
thousand eight hundred and sixty.
JOZE LUIS.
