WHEREAS Her 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 Fifteenth day of April,
One thousand eight hundred and forty-eight, did, for Herself, Her heirs and
successors, give and grant unto me, the said Henry Henson Henson, my
exors, adñiors, and assigns, Her especial licence, full power, sole privilege

page_text: and authority, that I, the said Henry Henson Henson, my exors, admors,
and assigns, my and their deputies, servants, or agents, and such others as I,
the said Henry Henson Henson, my exors, admors, or assigns, should
agree with, and no others, should and lawfully might make, use, exercise, and
vend, an Invention of me, the said Henry Henson Henson, therein entitled
"CERTAIN IMPROVEMENTS IN RAILWAY CARRIAGES AND WAGONS, AND IN VESSELS OF
CAPACITY EMPLOYED IN THE STORING AND CONVEYANCE OF EXPLOSIVE SUBSTANCES;"
within that part of the United Kingdom of Great Britain and Ireland called
England, the Dominion of Wales, and the Town of Berwick-upon-Tweed,
for the term of fourteen years from the date of the said Letters Patent.
And whereas I, the said Henry Henson Henson, in pursuance of a proviso
in the said Letters Patent for that purpose contained, caused a Specification
or instrument in writing, under my hand and seal, bearing date the Fourteenth
day of October, One thousand eight hundred and forty-eight, and particularly
describing the nature of the said Invention, and in what manner the same
was and is to be performed, to be duly enrolled in. Her Majesty's High Court
of Chancery in England on the same Fourteenth day of October, One
thousand eight hundred and forty-eight, and within the time limited for that
purpose by the said Letters Patent: And whereas by an indenture dated the
Tenth day of February, One thousand eight hundred and forty-nine, and
expressed to be made between-me,. the said Henry Henson Henson, of the one
part, and me, the said Jeremiah Lorkin, of the other part,. oue. equal undivided
third part or share of and in the said Letters Patent, and of and in all and
singular, the liberties, privileges, profits, emoluments, and. advantages of the
same respectively, was, by me, the said Henry Henson Henson, assigned to
me, the said Jeremiah Lorkin; and whereas the Inventions or improve-
ments for which such Letters Patent were granted, as described in the
said Specification, consisted,- Firstly, of certain improved modes of con-
structing the wheels of railway carriages and wagons. Secondly, of improve-
ments in the wheels of railway carriages and wagons, having relation to
the axles. Thirdly, of new or improved methods of constructing springs
for railway carriages and wagons. Fourthly, of certain improvements in
covered goods wagons for railways, constructed according to certain Letters
Patent granted to me, the said Henry Henson Henson, in the year One
thousand eight hundred and forty-six. And; lastly, of certain new or
improved methods of constructing 'vessels of capacity employed in the
storing and conveyance of explosive substances: And whereas the claims
made by me, the said Henry Henson Henson, in respect of my said
Inventions by the Specification in which my said Inventions are described

page_text: amount altogether in number to thirty-two: And whereas such parts of the said
Inventions or improvements as relate respectively to the construction of spiral
conical springs, covered goods wagons, and vessels for storing and conveying
explosive substances, have been extensively used by. us, Henry Henson:
Henson and Jeremiah Lorkin, our agents or licencees, and in our belief
such Inventions or improvements were. unknown before the .date.of the said
Letters Patent, and their introduction has been of great public benefit and
advantage: And whereas the other parts of the Inventions or improvements
for which the said Letters Patent were granted have been little if at all used,
and we are advised that, in consequence of the number of claims made by:
the said Specification, the expence and difficulty of any legal proceedings
which may be taken by us in support or defence of the said Letters Patent
will be materially and unnecessarily increased:And whereas we are desirous:
of disclaiming such parts of the Inventions for which the said Letters Patent
were granted as have not been effectively worked by us, our agents or
licencees, as aforesaid: And. whereas we have obtained leave of Sir A. J.. E.
Cockburn, Her Majesty's Attorney: General, certified by his fiat and signature,
to enter with the Clerk of the Patents for England, pursuant to the Statutes
in-that case made-and provided, a Disclaimer and Memorandum of Alteration
of certain parts of the said Specification.
NOW KNOW YE, therefore, that we, the said Henry Henson Henson and
Jeremiah Lorkin, by. and with the leave of Sir A. J. E. Cockburn, Her
Majesty's Attorney General, do hereby disclaim so much of the said Specifi-:
cation as follows, that is to say:— : :
All the claims thereby made in respect to wheels.
All the claims thereby made in respect to axles, and the 1st, 2nd, 3rd, and
4th, claims thereby made in respect to springs, together with all such parts
of the said Specification as describe the manner in which such wheels and
axles, and also the springs represented in Figures 69, 70, 71, 72, 72, 73, 74,
75, 76, 77, and 78, of the Drawings annexed to the said Specification are
constructed.
And whereas we are informed that the several expressions "conical spiral
springs, reducing spiral and conical forms of diminishing spirals," in those
parts of the said. Specification which relate to the springs represented. in
Figures 79 and 80 of the Drawings annexed to the said Specification, and to
the claim made in respect of such last-mentioned springs might be understood
as applying to the conical form alone of such springs, and not to the tapering
form of the metal of which such springs are made. Now I, the said Henry
Henson Henson, hereby state that by the term, reducing spiral and diminishing

page_text: spirals, I meant and mean spirals composed of a bar, which bar itself dimi-
nishes or tapers from the base to the apex, which I had considered had been
expressed by the use of the term reducing spiral and diminishing spirals
in addition to the term conical form.
And we, the said Henry Henson Henson and Jeremiah Lorkin, do hereby
state and declare that our reasons for making such Disclaimer and Alteration
as aforesaid are,-
First, that the said Specification is encumbered with a number of claims
which have proved to be useless, and may occasion injury and expense to us
in proceedings as to other portions of the Inventions described in the said
Specification; and,
Secondly, that the description and claim in the said Specification contained,
relating to spiral conical springs, may possibly be construed as including
springs of another and different description from those for which the said
Letters Patent were intended to be obtained, and may have a more extended
effect than was contemplated or intended by me, the said Henry Henson
Henson, when the said Specification was enrolled.
And we, the said Henry Henson Henson and Jeremiah Lorkin, do hereby
further declare that the above-written Disclaimer and Memorandum of
.Alteration are not, nor is either of them respectively, or any part thereof,
respectively, intended to extend the exclusive right granted by the said
Letters Patent, and that these, Presents shall not extend the said exclusive
right in any way whatsoever.
In witness whereof, the said parties to these Presents have hereunto set
their hands and seals, this Fourth day of March, in the year of our
Lord One thousand eight hundred and fifty-six.

page_text: Times and Morning Herald newspapers, and such advertisements having
been duly made, and no objection made to the said application, I have
accordingly granted leave to the said Henry Henson Henson and Jeremiah
Lorking to file their said Disclaimer and Memorandum of Alterations,
pursuant to the Statute in such case made and provided. And I hereby
certify that any action may be brought in respect of any infringement
committed prior to the filing of this Disclaimer, notwithstanding the entry
or filing of the same pursuant to the Statute in that case made and pro-
vided, save and except that no action can be brought against John Brown,
of the Atlas Steel Works, Sheffield, in the County of York, for any such
infringement.
AND BE IT REMEMBERED, that on the Nineteenth day of March, in
the year of our Lord 1856, the aforesaid Henry Henson Henson and
Jeremiah Lorkin came before our said Lady the Queen in Her Chancery,
and acknowledged the Disclaimer aforesaid, and all and every thing therein
contained and specified, in form above written. And also the Disclaimer
aforesaid was stamped according to the tenor of the Statute made for that
