Year: 1871

page_text: LETTERS PATENT to Nathaniel Clayton and Joseph Shuttleworth, of
the City of Lincoln, Engineers, for the Invention of "IMPROVEMENTS
IN THE CONSTRUCTION AND MODE OF FIXING THE BRACKETS WHICH CARRY-
PROVISIONAL SPECIFICATION left by the said Nathaniel Clayton and
Joseph Shuttleworth at the Office of the Commissioners of Patents,
with their Petition, on the 29th July 1871.
We, NATHANIEL CLAYTON and JOSEPH SHUTTLEWORTH, of the City of
Lincoln, Engineers, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN THE CONSTRUCTION AND MODE OF FIXING THE BRACKETS
WHICH CARRY THE CRANK SHAFT BEARINGS OF PORTABLE AND OTHER STEAM
ENGINES," to be as follows:-
This Invention relates to certain improvements in the construction
and mode of fixing the brackets which carry the crank shaft pedestal
of bearings of portable, fixture, and traction engines, whereby greater

page_text: lightness, a more rigid connection between crank shaft and cylinders,
and due provision for expansion and contraction are obtained, and
consists in forming such brackets of one or more plates of wrought
iron or other suitable metal so constructed as to extend transversely
across the boiler to which they are firmly riveted or otherwise secured,
and are further secured by being connected by strong longitudinal stays
to the steam cylinder and boiler or cylinders, whereby a rigid connection
is made between them whilst at the same time the flexibility of the
transverse plates forming the brackets will admit of due expansion and
contraction.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Nathaniel Clayton and Joseph Shuttleworth in the
Great Seal Patent Office on the 20th January 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, NATHANIEL
CLAYTON and JOSEPH SHUTTLEWORTH, of the City of Lincoln, Engineers,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-ninth day of
in the year
of our Lord One thousand eight hundred and seventy-one, in the
.
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Nathaniel Clayton and Joseph Shuttleworth,
Her special license that we, the said Nathaniel Clayton and Joseph
Shuttleworth, our executors, administrators, and assigns, or such others
as we, the said Nathaniel Clayton and Joseph Shuttleworth, our
executors, administrators, or 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
"IMPROVEMENTS IN THE CONSTRUCTION AND MODE OF FIXING THE BRACKETS WHICH
CARRY THE CRANK SHAFT BEARINGS OF PORTABLE AND OTHER STEAM ENGINES,"
upon the condition (amongst others) that we, the said Nathaniel Clayton
and Joseph Shuttleworth, our executors or administrators, by an instru-
ment in writing under our hand and seal, should particularly describe
and ascertain the nature of the said Invention, and in what manner the

page_text: 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 we, the said Nathaniel Clayton and Joseph
Shuttleworth, do hereby declare the nature of said Invention, and in
what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, reference being had
to the accompanying Drawings and to the letters and figures marked
thereon, that is to say :-
Our said Invention relates to certain improvements in the construction
and mode of fixing the brackets which carry the crank shaft pedestals
or bearings of portable, portable fixture, and traction engines, whereby
greater lightness, a more rigid connection between crank shaft and
cylinders, and due provision for expansion and contraction are obtained,
and consists in forming such brackets of one or more plates of wrought
iron or other suitable metal so constructed as to extend transversely
across the boiler to which they are firmly rivetted or otherwise secured,
and are further secured by being connected by strong longitudinal stays
to the steam cylinder and boiler or cylinders, whereby a rigid connection
is made between them whilst at the same time the flexibility of the
transverse plates forming the brackets will admit of due expansion and
contraction.
And in order that our said Invention may be fully understood, we will
now proceed more particularly to describe the same, and for that purpose
shall refer to the two Figures on the annexed Sheet of Drawings, the
same letters of reference indicating corresponding parts in both the
Figures.
Figures 1 and 2 represent a side elevation and transverse section of a
portable engine boiler having the before-mentioned brackets secured and
fixed thereon according to our said Invention.
A, A, represent the wrought-iron or other suitable metal transverse
plates, which are rivetted or bolted to the boiler to carry the crank shaft
pedestals or bearings B, B, which pedestals or bearings are firmly tied
to the cylinders or boiler by strong longitudinal stays, one of which only
can be seen in the Drawing at C, thereby effecting a rigid connection
between the crank shaft and the cylinder, whilst at the same time
provision is made for the expansion and contraction of the boiler by the
inherent elasticity and flexibility of the transverse plates A.

page_text: Having now described and particularly ascertained the nature of our
said Invention, and the manner in which the same is or may be used
or carried into effect, we would observe in conclusion that what we
consider to be novel and original, and therefore claim as the Invention
secured to us by the herein-before in part recited Letters Patent
is, the application and use to and in the construction of portable,
portable fixture, and traction engines of a transverse plate or plates of
wrought iron or other suitable metal carrying the crank shaft bearings
in conjunction with longitudinal stays extending to the cylinder or
boiler, substantially in the manner and for the purpose herein-before
described.
In witness whereof, we, the said Nathaniel Clayton and Joseph
Shuttleworth, have to this our Specification set our hands and
seals, the Sixteenth day of December One thousand eight hundred
and seventy-one.
NATHANIEL CLAYTON.
JOSEPH SHUTTLEWORTH.
