IMPROVEMENTS IN HORSE-SHOE NAILS
Year: 1878

page_text: LETTERS PATENT to Gorard Wenzeslaus von Nawrocki, of the Firm of J. Brandt
and G. W. v. Nawrocki, of 124, Leipzigerstrasse, Berlin, Germany, for the
Invention of "IMPROVEMENTS IN HORSE-SHOE NAILS." A communication
from Hugo Moeller, Julius Moeller, and Clemens Schreiber, all of Berlin,
Germany.
Sealed the 24th December 1878, and dated the 25th June 1878.
PROVISIONAL SPECIFICATION left by the said Gerard Wenzeslaus_von
Nawrocki at the Office of the Commissioners of Patents on the 25th June
1878.
GERARD WENZESLAUS VON NAWROCKI, of the Firm of J. Brandt and G. W. v.
Nawrocki, of 124, Leipzigerstrasse, Berlin, Germany. "IMPROVEMENTS IN HORSE-
SHOE NAILS." (A communication from Hugo Moeller, Julius Moeller, and Clemens
Schreiber, all of Berlin, Germany.)
Horse-shoe nails have heretofore usually been made with a flat shank of a
rectangular section. By reason of this form of nails, even when well made, the
hoof often cracks and splits, so that the horse-shoe becomes loose or falls off, and the
horse becomes useless until the hoof has grown again.
The object of this Invention is to construct a horse-shoe nail without these
defects. For this purpose, according to this Invention, the shank of the nail is
tapered off from the neck on two sides down to the taper point, so that the shank
presents a triangular section. The taper point of the nail may also if desired be
tapered off similarly.
Besides overcoming the aforesaid defect inherent in horse-shoe nails of usual form,
and thus preventing the cracking and splitting of the hoof, the following advantages
are obtained by this new form of nail..
Firstly. The nail requires less force to drive it into the hoof because of its
form.

page_text: Secondly. The protruding end of the nail after being driven in is more easily
bent over because the two ends of the shank are thinner.
Thirdly. The nail takes easier the direction towards the outside of the
hoof.
The shank is purposely made with the full flat back surface because the
protruding end of the nail, after being driven in, fits closer against the hoof and
holds better than if the nail were tapered off on both sides, that is, if made square
instead of rectangular. The bayonet-like rib on one side at the same time imparts
strength in the right direction to the protruding end when the nail is driven in.
This nail is also more suitable for the new mode of shoeing, according to which the
nail is not driven in the direction of the fibres or growth of the hoof (thereby
easily splitting the hoof), but according to the width of the hoof (across the fibres
or growth of the hoof). For this purpose the ordinary nail is not sharp enough and
tears the hoof, while this bayonet-formed nail easily penetrates across without
tearing. This shank can of course be made to suit any size or shape of horse-shoo
nail head and can be made by hand or machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Gerard Wenzeslaus von Nawrocki in the Great Seal Patent Office on
the 24th December 1878.
GERARD WENZESLAUS VON NAWROCKI, of the Firm of J. Brandt and G. W. v.
Nawrocki, of 124, Leipzigerstrasse, Berlin, Germany. "IMPROVEMENTS IN HORSE-
SHOE NAILS." (A communication from Hugo Moeller, Julius Moeller, and Clemens
Schreiber, all of Berlin, Germany.)
Horse-shoe nails have heretofore usually been made with a flat shank of a
rectangular section. By reason of this form of nails, even when well made, the
hoof often cracks and splits, so that the horse-shoc becomes loose or falls off, and the
horse becomes useless until the hoof has grown again.
The object of this Invention is to construct a horse-shoe nail without these
defects. For this purpose, according to this Invention, the shank of the nail is
tapered off from the neck on two sides down to the taper point, so that the shank
presents a triangular section. The taper point of the nail may also, if desired, be
tapered off similarly.
In the accompanying Drawings are shown three different forms of nail, the
Figures marked a being front elevations; Figures b, side views; Figures c, back
elevations; and Figures d, cross sections on the lines M, N ; the sides are shown
tapered off down to the taper point only.
Besides overcoming the aforesaid defect inherent in horse-shoe nails of usual form,
and thus preventing the cracking and splitting of the hoof, the following advantages
are obtained by this new form of nail.

page_text: Firstly. The nail requires less force to drive it into the hoof because of its
form.
Secondly. The protruding end of the nail after being driven in is more casily
bent over because the two sides of the shank are thinner.
Thirdly. The nail takes easior the direction towards the outside of the
hoof.
The shank is purposely made with the full flat back surface because the
protruding end of the nail, after being driven in, fits closer against the hoof, and
holds better than if the nail were tapered off on both sides. The bayonet-like rib
on one side at the same time imparts strength in the right direction to the
protruding end when the nail is driven in. This nail is also more suitable for the
new mode of shoeing, according to which the nail is not driven in in the direction
of the fibres or growth of the hoof (thereby easily splitting the hoof), but according
to the width of the hoof across the fibres or growth of the hoof. For this purpose
the ordinary nail is not sharp enough and tears the hoof, while this bayonet-
formed nail casily penetrates across without tearing. This shank can of course be
made to suit any size or shape of horse-shoe nail head and can be made by hand or
machine.
We claim the triangular horse-shoe nail shank, substantially as set forth.
In witness whereof, I, the said Gerard Wenzeslaus von Nawrocki, have here-
unto set my hand and seal, this Twenty-first day of December, in the year
of our Lord One thousand eight hundred and seventy-eight.
