Improvements in or relating to the Piles of Groynes and the like.
I, HENRY EDWARD STILGOE, of Parade Cottage, Sandgate, in the County of
Kent, Associate Member of the Institution of Civil Engineers, do hereby declare
the nature of this invention and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
It has become a frequent practice to construct the groynes erected at various
points along the coast in connection with sea defence work, etc. for the purpose of
causing the collection of beach at any desired place, of old railway rails and
timber, the railway rails being used as piles and struts, to which the timber is
secured. The piles have hitherto usually been formed of a pair of double-headed
rails arranged at a given distance apart and welded together at their lower ends
to form a point so as to facilitate the driving of the same. This welding, which
cannot generally be done near where the groyne is being erected, occupies
considerable time and is very costly. Moreover, piles thus formed cannot always
be kept vertical whilst being driven and unless the greatest care is taken in making
them the tops of the rails are seldom perfectly level; they are thus rendered
liable to be split at the weld by an uneven blow of the monkey or driver, whereby
the withdrawing and re-welding of the pile are necessitated.
The accompanying drawings illustrate my invention according to which I provide
a foot or point of suitable material such as cast iron or steel adapted to be attached
to the two rails or the like of which the pile is to be formed, thereby greatly
reducing the cost of the pile, which will not be liable to the damage before
mentioned, and, at the same time, rendering it possible, when driving the same, to
maintain it in a vertical position with comparative case, owing to the point being
quite true.
Fig. 1 is an elevation of a pile provided with a foot or point according to this
invention; aud
Figs. 2 and 3 are respectively an elevation and a plan of the foot or point
detached.
The foot or point comprises an inverted cast iron or steel pyramid a having
extending centrally from its base an extension b of approximately rectangular form
in plan against which the rails c c fit snugly, as indicated by the dotted lines
in Fig. 3, and through which is formed a bolt hole d, the arrangement being such
that, when the rails are placed one on each side of the said extension and secured
thereto by means of a bolt e passing through the bolt hole d and through suitable
holes formed in the rails, their ends will rest firmly on the base of the pyramid, as
shown in Fig. 1.
The dimensions of the foot or point may conveniently be approximately those
indicated on the drawings, which show a pile constructed for use with timbers three
inches in thickness, the timbers being, as usual, placed on edge between and bolted
to the pairs of rails forming the piles which are bent towards each other from
below the timbers so as to fit the shank; it is of course to be understood that these
dimensions may vary according to circumstances.

page_text: Having now particularly described and ascertained the nature of the said inveu-
tion and in what manner the same is to be performed I declare that what I
claim is :-
A foot or point for the piles of groynes and the like substantially as hereinbefore
described with reference to and shown in the accompanying drawings.
