Improvements in or relating to Horse-shoes.

Manufacturer.
I, WILLIAM LLOYD WISE, of 46 Lincoln's Inn Fields, in the County of
Middlesex, Consulting Engineer and Chartered Patent Agent, do hereby declare
the nature of this invention to be as follows:-
In order to prevent shoed animals slipping on ice and slippery ground, horse-
shoes have hitherto been employed with calks that are screwed into or otherwise
secured to the shoe. With arrangements of this kind the calks are easily worn and
blunted; moreover they are easily lost since the hold is a defective one, and do not
provide a good tread owing to the comparatively small bearing surface, the animals
being thus prevented from obtaining a really firm foothold.
a
The object of this invention is to obviate these disadvantages.
The horse-shoe is formed at the required points with grooves into which spring
insertion pieces or calks are inserted by means of suitable tongs or otherwise, the
relative form of the grooves and of the calks being such that the latter will, on
being released after insertion in the grooves, bite against the walls thereof in such
Horse-shoes
manner as to prevent them becoming accidentally displaced.
according to this invention can be used without the calks in which case it is
advantageous to fill up the grooves with some suitable material which is easily
removed; such as hemp, tow, rubber. The grooves and calks may be of various
forms in plan provided the calks cannot be inserted into the grooves unless bent
more or less out of their normal form. For example the grooves may be curved, in
which case the calks may be straight, angular or curved to greater or less extent
than the grooves in the shoes, or the grooves may be straight and the calks
of curved or angular form.
By bending the spring calks out of their normal form by means of a suitably
formed pair of tongs, a vice or other apparatus, or by driving them in by means of
a hammer, they are easily inserted in the corresponding grooves, so that their
tendency to assume their normal form causes them to become immovably clamped
in the grooves, as will be readily understood. The calks may be easily removed
when desired. The bearing-surfaces of these calks may be enlarged or sharpened
as may be desired and they may be of uniform thickness throughout or not.
The calks are simply cut of the desired length from rolled iron or steel of
suitable form and the grooves in the shoes may be formed either by machine or by
hand, simply by driving in a suitably formed punch.

A communication from abroad by ROBERT ZAPP, of Düsseldorf, Germany,
Manufacturer.
I, WILLIAM LLOYD WISE, of 46 Lincoln's Inn Fields, in the County of
Middlesex, Consulting Engineer and Chartered Patent Agent, 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 :-
In order to prevent shoed animals slipping on ice and slippery ground, horse-
shoes have hitherto been employed with calks that are screwed or otherwise secured
to the shoe. With arrangements of this kind the calks are easily worn and
blunted; moreover they are easily lost since the hold is a defective one, and do not
provide a good tread owing to the comparatively small bearing surface, the animals
being thus prevented from obtaining a really firm foothold.
The object of this invention is to obviate these disadvantages.
Referring to the accompanying drawings,
Fig. 1 is an underside view of a horse-shoe provided with calks according to this
invention;
Fig. 2 is a side elevation ;
Figs. 3 and 4 are views at right angles of a calk according to this invention held
in the jaws of a suitably formed pair of tongs; and
Figs. 5 to 18 are underside views of various forms of calks held in suitably
formed grooves or recesses in the underside of a horse-shoe.
The horse-shoe is formed at the required points with grooves or recesses a
(hereinafter called grooves) into which spring insertion pieces or calks 6 are
inserted by means of suitable tongs, such as those illustrated in Figs. 3 and 4, or
otherwise, the relative form of the grooves and of the calks being such that the
latter will, on being released after insertion in the grooves, bite against the walls
thereof in such a manner as to prevent them becoming accidentally displaced.
Horse-shoes according to this invention can be used without the calks in which
case it is advantageous to fill up the grooves with some suitable material which is
easily removed; such as hemp, tow, or rubber.
The grooves and calks may be of various forms in plan provided the calks cannot
be inserted into the grooves unless bent more or less out of their normal form,
(that is to say the form which they assume when out of the horse-shoe and
unrestrained.
For example the grooves may be curved as shewn in Figs. 1 and 2 and Figs. 5
to 16 inclusive in which case the calks may be angular, as shewn in Figs. 9 to 18,
or curved to a greater extent than the grooves in the shoes as shewn in Fig. 1 and
in Figs. 5 to 8 inclusive or vice versa; or they may be straight; or the grooves may
be straight and the calks of curved form as shewn in Figs. 17 and 18 or of angular
form.
By bending the spring calks out of their normal form by means of a suitably
formed pair of tongs (Figs. 3 and 4) a vice, or other apparatus, or by driving them
in by means of a haminer, they are easily inserted into the corresponding grooves,
so that their tendency to assume their normal form causes them to become
immovably clamped in the grooves as will be readily understood.
The calks may be easily removed when desired.
The bearing surfaces of these calks may be enlarged or sharpened as may be
desired and they may be of uniform thickness throughout or not.
The calks are simply cut of the desired length from rolled iron or steel of suitable
form and the grooves in the shoes may be formed either by machine or by hand,
simply by driving in a suitably formed punch.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. A horse-shoe formed with spring calks that are inserted into grooves or
recesses in the underside of the shoe, upon being bent out of their normal form,
the arrangement being such that the calks, when inserted, will bite or press
strongly against the walls of the recesses and be thus held in place substantially as
described.
2. The improvements in or relating to horse-shoes hereinbefore described with
reference to and shown in the accompanying drawings.
