Berlin, Germany. "IMPROVEMENTS IN HORSE SHOES." A communication from
Adolf Finze, of Knittelfeld Stiermark, Austria.
This Invention relates to improvements in the construction of horse shoe toes
whereby they may be renewed when required without removing the horse shoe from
the hoof.
It consists in forming the toe by 2 or more screws screwed close together into
the horse shoe. These two screws have alternately right and left handed threads,
while a splint or shiver is put between the crossheads so that as the screws are
contained to turn backwards or loosen themselves they are squeezed or tightened
against the splint or shiver, and so prevented from turning.
The toe screws being worn they can be changed by first removing the splint or
shiver, and then turning back the screws in the ordinary manner; new toe screws
having been screwed in the splint or shiver will be placed between the toe screw
heads, and a sharp toe thereby re-established.

GERARD WENZESLAUS von NAWROCKI, Proprietor of the Firm of J. Brandt and
G. W. v. Nawrocki, Patent Solicitor and Civil Engineer, of No. 124, Leipziger Strasse,
Berlin, Germany.. IMPROVEMENTS IN HORSE-SHOES." A communication from
Adolf Finze, of Knittelfeld Stiermark, Austria.
<
According to this Invention a horse shoe is roughed by inserting in it chisel
headed screws so arranged that they can be applied without taking off the shoe,
and that they cannot loosen out when in use.
Fig. 1 of the accompanying Drawings is a plan, and Fig. 2 is a front view of a
horse-shoe roughed according to this Invention; Fig. 3 is a transverse section on
A, B; and Fig. 4 shews the split pin for preventing the screws from unscrewing.
The two chisel headed screws a and b are made with right and left hand threads,
so that they are screwed into the shoe by turning them in opposite directions.
After screwing them in, the split pin d is driven in between them and opened a
little at the end so that it cannot be shaken out. This pin prevents the screws a, b,
from turning round so as to become unscrewed, any turning of the screws having
the effect of pinching the pin more tightly. There might obviously be more than
two screws inserted side by side, or there might be several sets of screws inserted
in different parts of the shoe.
Having thus described the nature of the said Invention and in what manner
the same is to be performed, as communicated to me by my correspondent, I
claim,―
First. The use for roughing horse-shoes of two or more chisel headed screws
screwed into the metal of the shoe side by side with split pins driven between them,
substantially as herein described.
Second. Making the screws referred to in the preceding claim with right and
left threads, as and for the purpose herein set forth.
In witness whereof, I, the said Gerard Wenzeslaus von Nawrocki, have
hereunto set my hand and seal, this Eighth day of October, in the year
of our Lord One thousand eight hundred and eighty one.
