IMPROVEMENTS IN IRON PILES AND COLUMNS
Year: 1867

page_text: LETTERS PATENT to Joseph Westwood, of Tredegar House, Bow, in the
County of Middlesex, Engineer, and Robert Baillie, of Leyton, in the
County of Essex, Engineer, for the Invention of "IMPROVEMENTS IN IRON
PILES AND COLUMNS."
Sealed the 24th April 1867, and dated the 13th February 1867.
PROVISIONAL SPECIFICATION left by the said Joseph Westwood and
Robert Baillie at the Office of the Commissioners of Patents, with
their Petition, on the 13th February 1867.
We, JOSEPH WESTWOOD, of Tredegar House, Bow, in the County of Mid-
dlesex, Engineer, and ROBERT BAILLIE, of Leyton, in the County of Essex,
Engineer, do hereby declare the nature of the said Invention for "IMPROVE
MENTS IN IRON PILES AND COLUMNS," to be as follows:-
Our Invention has for its object the prevention of injury to iron piles and
columns at the junctions of the several lengths thereof by the decay from
corrosion or other cause of the bolts by which the external or internal flanges
of such lengths have heretofore been fastened together; and our Invention
consists in constructing the several lengths of piles and columns with dovetailed
flanges, by means of which they are fastened together without the aid of bolts,
as usual.
On the ends of two lengths of pile or column intended. to be fastened;
together are formed flanges with dovetailed projections and spaces respectively

page_text: corresponding in such a manner as to break joint when one of the lengths is
turned on the other, and thereby form an effectual junction of the two flanges
thus brought together. Any convenient form of bolt or stop for preventing
the turning of one flange on the other after their junction may be used if
required.
For underground piles or columns the flanges are or may be formed inside,
and thereby preserve an even junction of the lengths on the outside; and for
those parts of piles or columns which are above ground the flanges are or may
be formed outside, thereby producing an even junction of the lengths on the
inside. In the latter case the outside flanges may be ornamental, as required.
Our Invention relates to piles or columns whether screwed or driven into
the ground.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Westwood and Robert Baillie in the Great Seal
Patent Office on the 13th August 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOSEPH
WESTWOOD, of Tredegar House, Bow, in the County of Middlesex, Engineer,
and ROBERT BAILLIE, of Leyton, in the County of Essex, Engineer, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of February, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Joseph Westwood and Robert Baillie, Her special licence that we,
the said Joseph Westwood and Robert Baillie, our executors, administrators,
and assigns, or such others as we, the said, Joseph Westwood and Robert
Baillie, our 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 "IMPROVEMENTS IN IRON PILES AND
COLUMNS," upon the condition (amongst others) that we, the said Joseph
Westwood and Robert Baillie, our executors or administrators, by an instru-
ment in writing under our, or their, or one of their hands and seals, should
particularly describe and ascertain the nature of the said Invention, and in
what manner the same was to be performed, and cause the same to be filed

page_text: in the Great Seal Patent Office within six calendar months next and imme-
diately 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 ha
annexed, and to the letters and figures marked thereon (that is to sayog
Our Invention of "Improvements in Iron Piles and Columns" has fo
object the prevention of injury to the same at the junctions of the seve
lengths thereof by the decay from corrosion or other cause of the bolts by
which the external or internal flanges of such lengths have heretofore been
fastened together; and our Invention consists in constructing the several
lengths of piles and columns with dovetailed flanges by means of which they
are fastened together without the aid of bolts, as usual.
On the ends of two lengths of pile or column intended to be fastened together
are formed flanges with dovetailed projections and spaces respectively corre-
sponding in such a manner as to break joint when one of the lengths is turned
on the other, and thereby form an effectual junction of the two flanges thus
brought together. Any convenient form of bolt or stop for preventing the
turning of one flange on the other after their junction may be used if
required.
For underground piles or columns the flanges are or may be formed inside
and thereby preserve an even junction of the lengths on the outside; and for
those parts of piles or columns which are above ground the flanges are or may
be formed outside, thereby producing an even junction of the lengths on the
inside. In the latter case the outside flanges may be ornamental, as
required.
Our Invention relates to piles or columns whether screwed or otherwise.
driven or sunk into the ground.
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 by
reference to the accompanying Drawings, in which are represented portions of
piles or columns with junctions constructed in the manner above referred to.
DESCRIPTION OF DRAWINGS.
Fig. 1 is a partial section showing the junction of two lengths of a pile or
column with outside flanges; Fig. 2 is an underneath plan of the upper
length; and Fig. 3 is a plan of the lower length; Figures 4, 5, and 6 are
corresponding views, showing portions of a pile or column joined by means of

page_text: inside flanges. In these several Figures the same letters of reference indicate
corresponding parts.
A is the upper length of a pile or column (which in Fig. I is represented
in section); B is the lower length of the same, which is represented in the
same Figure partly in section and partly in elevation; C, C, are dovetailed
tions fitting into corresponding spaces D, D, the projections and spaces
so arranged in relation to each other as to admit of the flanges of the
ths A and B being put together, and on the upper flange being turned to
use the projections and spaces to become interlocked, and thereby effect a
secure fastening of the flanges together without the aid of bolts, as usua
In Fig. 4 the upper length A is shewn partly in elevation and partly in
section, and the lower length B is shown entirely in section.
Having thus described the nature of the said Invention, and in what minner
the same is to performed, we hereby declare that what we claim as of our
Invention is the construction of lengths of miles and columns with dovetailed
flanges for the purpose of fastening together such lengths without the aid of
bolts, as herein-before described.
