IMPROVEMents in IRON PILES AND COLUMNS
Year: 1874

page_text: LETTERS PATENT to Joseph Westwood, of London Yard, Isle of
Dogs, in the County of Middlesex, Engineer, and Robert Baillie, of
the same Place, Engineer, for the Invention of “IMPROVEMents in
IRON PILES AND COLUMNS."
Sealed the 14th August 1874, and dated the 24th June 1874.
PROVISIONAL SPECIFICATION left by the said Joseph Westwood and
Robert Baillie at the Office of the Commissioners of Patents, with
their Petition, on the 24th June 1874.
WC, JOSEPH WESTWOOD, of London Yard, Isle of Dogs, in the County
of Middlesex, Engineer, and ROBERT BAILLIE, of the same Place,
Engineer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN IRON PILES AND COLUMNS," to be as follows :—
Our Invention has reference to the construction of the junctions
of piles and columns in such a manner as to admit of their being
fastened together as required without the aid of bolts. The junctions of

page_text: piles and columns hitherto constructed in this manner have been found
wanting in strength to resist lateral or torsive strain.
Now our Invention has for its object the construction of the said
junctions in such a manner as to give them the requisite stiffness and
strength to resist the strains to which they are liable when fitted and in
usc. For this purpose one member of the junction is formed with an
internal flange of suitable depth, which flange is adapted to fit inside a
portion of the other member of the junction which is formed inside the
pile or column, and so as to give increased substance or thickness at such
part. By this means the junction is strengthened as required at that
part thereof where the substance or thickness of the said internal flange
is added to that of the said inside portion of the junction.
The two members of the junction have also formed on them projec-
tions and cavities respectively corresponding in such a manner as to
break joint when one of the lengths of pile or column is turned on the
other in order to fasten the junctions of this description together without
the aid of bolts.

greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her 2
Letters Patent, bearing date the Twenty-fourth day of June, in the
year of our Lord One thousand eight hundred and seventy-four, in the
thirty-eighth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto us, the said Joseph Westwood and Robert
Baillie, Her special licence, that we, the said Joseph Westwood and a
Robert Baillic, our exccutors, administrators, and assigns, or such others
as we, the said Joseph Westwood and Robert Baillic, our executors,
administrators, and assigns, should at any time agree with, and no

page_text: 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
IRON PILES AND COLUMNS," upon the condition (amongst others) that we, the
said Joseph Westwood and Robert Baillie, our executors or admini-
strators, by an instrument in writing under our, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of
of the said Invention and in what manner the same was to be performed,
and cause the same to be filed in the Great Scal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that we, the said Joseph Westwood and Robert
Baillie, do hereby declare the nature of our 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 Drawings hereunto annexed, and to the letters and figures marked
thereon (that is to say) :-
Our Invention of "Improvements in Iron Piles and Columns" has
reference to the construction of the junctions of piles and columns in
such a manner as to admit of their being fastened together as required
without the aid of bolts. The junctions of piles and columns hitherto
constructed in this manner have been found wanting in strength to resist
lateral or torsive strain.
use.
Now our Invention has for its object the construction of the said
junctions in such a manner as to give them the requisite stiffness and
strength to resist the strains to which they are liable when fitted and in
For this purpose one member of the junction is formed with an
internal flange of suitable depth, which flange is adapted to fit inside a
portion of the other member of the junction, which is formed inside the
pile or column, and so as to give increased substance or thickness at such
part. By this means the junction is strengthened as required at that
part thereof where the substance or thickness of the said internal flange
is added to that of the said inside portion of the junction.
The two members of the junction have also formed on them projec-
tions and cavities respectively corresponding in such a manner as to

page_text: break joint when one of the lengths of the pile or column is turned on
the other in order to fasten the junctions of this description together
without the aid of bolts.
Having thus stated the nature of the said Invention we will proceed to
describe more particularly in what manner the same is to be performed 5
by the aid of the accompanying Drawings, in which are represented two
forms of junctions for piles or columns constructed in the manner above
referred to
junction, the former member of which is shown in elevation and the
latter in vertical section.
:
Figures 6, 7, 8, 9, and 10, are corresponding Figures representing
another form of junction. In these several Figures the same letters of
reference indicate corresponding parts.
A is the spigot or plug end of the top length forming one member of
the junction; B is the faucet or socket end of the bottom length forming
the other member of the junction. In Figures 1, 2, 3, 4, and 5, C, C,
are a scries of external equidistant dovetailed projections cast on the
spigot or plug end of the top length, just under the shoulder of the shaft; '
and D, D, are corresponding equidistant and dovetailed projections
formed in the faucet or socket end of the bottom length, between which
the projections C, C, are capable of fitting; E, E, are two slots or
recesses formed in the lower length for the reception of the two projec-
tions F, F, on the upper length, by means of which the connection of the
two members of the junction is secured, as herein-after described.
In Figures 6, 7, 8, 9, and 10, the said projections C, C, are cast at the
extreme end of the top length, and not under the shoulder of the shaft;
and the slots and projections to prevent disjointing are in this case

described when applied to junctions of the kind described.
In witness, whereof, we, the said Joseph Westwood and Robert
Baillie, have hereunto set our hands and seals, the Twenty-second
day of December, in the year of our Lord One thousand eight
hundred and seventy-four.
