Gustav Schaper both of Hamburg Germany for an Invention of
"IMPROVEMENTS IN HORSE SHOES
"
PROVISIONAL SPECIFICATION left by the said Johann Joachim Otto Wilins
and Johann Hermann Gustav Schaper at the Office of the Commissioners of
Patents on the 23rd August 1883.
JOHANN JOACHIM OTTO WILMS and JOHANN HERMANN GUSTAV SCHAPER, both
of Hamburg, Germany "IMPROVEMENTS IN HORSE SHOES
"
This Invention relates to improvements in horse shoes with detachable calks;
and the object of our improvements is to facilitate the fastening of the detachable
calks to the horse shoe.
The calk is provided at its top with a cylindrical or polygonal projection, for the
reception of which corresponding cylindrical or polygonal recesses are cut out in
the body of the horse shoe. These recesses are arranged in such a manner as to
place their axis parallel or nearly parallel to the surface of the shoe.
The projection is placed into the recess and then the edge of the latter rivetted
by a few strokes of the hammer around the front of the projection, thus causing a
solid connection between the horse shoe and the calk. When the bur is cut away,
the calk may easily. be withdrawn from the horse shoe.

JOHANN JOACHIM OTTO WILMS and JOHANN HERMANN GUSTAY SCHAPER, of
Hamburg, Germany; "IMPROVEMENTS IN HORSE-SHOES"
This Invention relates to improvements in horse shoes with detachable calks,
and the object of our improvements is to secure, and yet to facilitate, the fastening
of the detachable calks to the horse shoe.
The calk therefore is provided at its top with a cylindrical or polygonal
projection, for the reception of which corresponding cylindrical or polygonal recesses
aro cut out in the body of the horse shoe. These recesses are arranged in such a
manner as to place their axes parallel or nearly parallel to the surface, and parallel
or angular to the symmetrical axis of the shoe.
In order to make our invention more clearly understood, we will describe it with
reference to the accompanying drawings.
Figure 1 is a view from below of a horse shoo in which two calks are placed in
their proper position, whilst the third one is taken out; figure 2 is a sectional side-
elevation of such horse shoe; figuro 3 is a back view of a horse shoe with a
complete set of detachable calks; figures 4, 5 and 6 are detailed views of the calk,
o is the calk, a is the cylindrical projection and 6 the recess for connecting the calk
with the shoe. The projection a is placed into the recess band then the edge of
the latter rivetted by a few strokes of the hammer around the front of the pro-
jection a in order to secure the calk. When the burr afterwards is cut away, the
calk may easily be withdrawn from the horse shoe, Instead of rivetting the edgo
of the recess, a pin d may be used, which passing a suitable boring of the calk,
engages into an inclined slot or recess e arranged at any convenient angle to the
દે
main recess b, as illustrated on the front calk Figure 1. Such pin d may be lifted
easily by driving a wedge shaped chisel into the recess e.
A modification is illustrated by Figures 7. 8 and 9 in which the projection a.is
not arranged at right angles to the calk but at any suitable angle, the position of
the recess 6 corresponding therewith.
b
Having thus fully described our invention, what we desire to Claim and secure
by Letters Patent is :-
First The mode of fastening and securing detachable calks to horse shoes as
described and illustrated by Figures 1 to 6.
Second-The mode of fastening detachable calks to horse shoes as described and
'illustrated by Figures 7 to 9.
In witness whereof we the said Johann Joachim Otto Wilms and Johann
Hermann Gustav Schaper have hereunto set our hands and seals this Nineteenth
day of February in the year of our Lord One thousand eight hundred and
eighty four.
