I LORENTZ ALBERT GROTH K.G.V. Civil Engineer and Proprietor of the Patent
Industrial and Financial Agency, 30 Finsbury Pavement London E.C. do hereby
declare the nature of said invention for A NEW OR IMPROVED METHOD OF FIXING
ORNAMENTAL IRON WORK a communication to me from abroad by Karl Louis
Gocht, Gentleman of Chemnitz, in the Kingdom of Saxony, German Empire to be
as follows: -
The object of this invention is to facilitate the use of figured or special iron in
the building trade.
The figured or special iron in one or more pieces screwed or rivetted, together
are secured by nails driven through the material to which it is to be fastened into
the ends of the iron which are specially prepared to receive them, for instance
when required to be fastened to a wooden beam-When the iron is in two
longitudinal pieces to be afterwards rivetted together, semi-circular recesses
bevelled at their outer edges are formed on the inner sides of the ends, which
when rivetted together form a nearly circular groove, with a wide mouthed, wedge
shaped opening. Into this groove is inserted a serrated bolt or rod of oval,
pointed, section or other suitable form, of the same length as the groove the ridge
facing the opening. The nail when driven into the wedge shaped opening is
deflected to the right or left by the ridge, and guided by the serrations, forms a
hook encircling the bolt when driven home, at the same time, by increasing its
diameter preventing the bolt being drawn out of the groove, thus firmly securing
the iron.
When only one piece of iron with a flat end is used, the grooved iron in a
separate piece is rivetted on.
If necessary the wide opening of the groove may be dispensed with.
In other cases the iron when in two pieces is formed one with a recess and the
other with a serrated projection at their ends, which when rivetted together fits
into the recess and forms a wide mouthed, vertically curved groove into which the
nails can be driven between the teeth or serrations, which guide them into the
form of a hook thus securing the iron to the wood through the nail is first passed.
This can be arranged to form a right or left handed hook.
When only one flat end is available the recess and serrated projection formed in
separate pieces are rivetted to the flat head.

I LORENTZ ALBERT GROTH K.G.V. Civil Engineer and Proprietor of the Patent
Industrial and Financial Agency 30 Finsbury Pavement London, E.C. do hereby
declare the nature of said invention for A NEW OR IMPROVED METHOD OF FIXING
ORNAMENTAL IRON WORK, & communication to me from abroad by Karl Louis Gocht,
Gentleman of Chemnitz in the Kingdom of Saxony, German Empire and in what
manner the same is to be performed to be particularly described and ascertained
in and by the following statement :—
The object of this invention is to facilitate the use of ornamental iron in the
building trade.
The ornamental or special iron in one or more pieces screwed or rivetted
together, are secured by nails driven through the material to which it is to be
fastened into the ends of the iron which are specially prepared to receive them, for
instance when required to be fastened to a wooden beam.
When the iron is in two longitudinal pieces to be afterwards rivetted together
Fig. 5 semi-circular recesses bevelled at their outer edges are formed on the inner
sides of the ends, which when rivetted together form a nearly circular groove with
a wide mouthed wedge shaped opening. Into this groove is inserted a serrated
bolt or rod c of oval pointed section or other suitable form of the same length as
the groove the ridge facing the opening.
The nail when driven into the wedge shaped opening is deflected to the right or
left by the ridge, and guided by the serrations forms a hook encircling the bolt
when driven home at the same time by increasing its diameter preventing the bolt
being drawn out of the groove thus firmly securing the iron.
When only one piece of iron with a flat head is used the grooved iron in a
separate piece is rivetted on Fig. 3.
If necessary the wide opening of the groove may be dispensed with.
In other cases the iron when in two parts is formed one with a recess and the
other with a serrated projection at their ends Figs. 1 and 2 which when rivetted
together fits into the recess and forms a wide mouthed vertically curved groove
into which the nails can be driven between the teeth or serrations, which guide
them into the form of a hook thus securing the iron to the wood through which
the nail is first passed.
This can be arranged to form a right or left handed hook.
When only one flat end is available the recess and serrated projection found in
separate pieces are rivetted to the flat head Fig. 4.
Figa. 6. 7. 8 and 9 show details in all of which a. b is the ornamental iron in two
pieces, the serrated bolt d the circular groove, e the serrated projection f the
recess head, n the nail and t the solid ornamental iron.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The method of fastening ornamental iron, by nails driven through the wood,
into vertically curved serrated grooves, formed in, or rivetted on, the heads of the
iron, or round a serrated, or corrugated bolt of pointed oval or other suitable
section in a circular groove, thus forming a hook that effectually secures the iron
as hereinbefore described and illustrated in the drawings.
