Office of the Commissioners of Patents, with his Petition, on the
25th September 1871.
I, JOHN BAILEY, of the City of Dublin, Civil Engineer, do hereby
declare the nature of the said Invention for "A NEW OR IMPROVED
JOINT FOR SCREW PILES," to be as follows:-
My Invention consists of a new or improved joint for screw piles.
This joint is constructed as follows:-The screw pile is provided with a
socket joint, the female part of which is checked out or has portions cut
away at diametrically opposite points to receive a cross bar. The male
part of the joint is forked, so as to slip over the cross bar and prevent

are then driven into holes drilled transversely in the male and female
portions, so as to hold them together.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Bailey in the Great Seal Patent Office on
the 23rd March 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
BAILEY, of the City of Dublin, Civil Engineer, send greeting.

page_text: My Invention consists of a new or improved joint for screw piles.
This joint is constructed as follows:-The screw pile is provided with a
socket joint, the female part of which is checked out or has portions cut
away at diametrically opposite points to receive a cross bar. The male
part of the joint is forked so as to slip over the cross bar and prevent
the pile from turning in the socket. One or more plugs or bolts is or
are then driven into holes drilled transversely in the male and female
portions so as to hold them together.
The annexed Drawings represent one of these joints, Figure 1 being. a
vertical section of the joint, Figure 2 a half plan of the faucet end A, A,
with the bar C removed, and Figure 3 a half plan of the spigot end
B, B, with the bar C shewn. It will be seen that the female part of the
joint is checked out or has portions cut away at D, D, as herein-before
explained, to receive the cross bar C, and that the male portion is forked,
as shewn, so as to slip over the cross bar C and prevent the pile from
turning in the socket; F, F, represent plugs or bolts which are driven
into drilled holes so as to hold the parts of the joint together.
And having now described the nature of my said Invention, and in
what manner the same is to be performed, I declare that I claim the new
or improved joint for screw piles herein-before described.
