PROVISIONAL SPECIFICATION.
Improvements in Hooks for Securing Lead Flashings, Water Pipes,
Gas Pipes, or the like.
We, JOIN CHARLES SPRAGG of Eyet Street, Leigh in the County of Lancaster
Plumber, and WILLIAM HENRY BOWLER of Sandileigh Withington, in the said
county, Architect and Surveyor do hereby declare the nature of this invention
to be as follows:-
This invention relates to hooks which are intended to secure or support lead
flashings and lead pipes such as for water or gas and is intended to render such
hooks more durable and to prevent them damaging the lead work with which
they come in contact. When used for flashings iron hooks in a comparatively short
time become useless owing to the heads becoming rusted or corroded and in hooks
used for supporting water and gas pipes the rubbing or movement of the pipe
owing to contraction and expansion against the hook tends to damage it. I find
that by constructing the hook with a covering or casing of lead surrounding the
head and if necessary part of the shank that not only is the corrosion prevented but
that the tendency of the hooks to damage the lead work is obviated.
In carrying out the invention I prefer to make the hooks of suitable construction
and shape and to cast over the head or bent part and upper end of the shank a
covering or casing of lead which will closely cover the iron.
Dated this 1st day of September 1896.

We, JOHN CHARLES SPRAGG, of Eyet Street, Leigh, in the County of Lancaster,
Plumber, and WILLIAM HENRY BOWLER, of Sandileigh, Withington, in the said
county, Architect and Surveyor, 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:-
This invention relates to hooks which are intended to secure or support lead
flashings and lead pipes such as for water or gas and is intended to render such
hooks more durable and to prevent them damaging the lead work with which
they come in contact. When used for flashings iron hooks in a comparatively short
time become useless owing to the heads becoming rusted or corroded and in hooks

that by constructing the hook with a covering or casing of lead surrounding the
head and if necessary part of the shank that not only is the corrosion prevented but
that the tendency of the hooks to damage the lead work is obviated.
The invention will be fully described with reference to the accompanying
drawings in which as examples three different forms of hooks are shown.
The hooks or fastenings A, which may be of any desired shape are made of iron
the head or hook a being made of approximately the shape required though it may
be made of any suitable size or shape to give the desired amount of firmness or
rigidity to the finished head.
The head or hook a of the iron is tinned and then cased with a covering of
lead B. The lead B is cast or run over the iron head a so as to closely cover the
iron and is afterwards compressed in such a manner as to form the shape of a
hook and wedge combined.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is ;-
Hooks for securing lead flashings water-pipes gas-pipes or the like constructed
with an iron head or hook encased in lead closely covering the iron substantially
as and for the purpose described.
