York Consulting Engineer of the London and Provincial Patent Agency for
an Invention of "IMPROVEMENTS IN HORSESHOES AND SHOES FOR OTHER
ANIMALS," Communicated to him from abroad by A Gauer of Hamburg in
the German Empire
PROVISIONAL SPECIFICATION left by the said Edward Edwards Hewett at
the Office of the Commissioners of Patents on the 14th October 1882.
EDWARD EDWARDS HEWETT of Sheffield in the County of York Consulting
Engineer of the London and Provincial Patent Agency-IMPROVEMENTS IN HORSE-
SHOES AND SHOES FOR OTHER ANIMALS (communicated to me from abroad by
A. Gauer of Hamburg in the German Empire)
This invention relates to improvements in horse-shoes and shoes for other
animals and to those descriptions of shoes in which the calks, toe-pieces or other
similar projections are removable and changeable
This invention consists of an improved construction of shoe and removeable
calks, (or other similar projections) in which the calk, has a tapered shank or
stem with one or more projections pins, or keys, at right angles, or otherwise, to
the longitudinal centre line of the shank or stem; the hole in the shoe-to receive
the calk-is of a form corresponding to that of the shank of the calk, and it has
two vertical and one horizontal key-ways, grooves, or recesses, so arranged as that
when the shank of the calk is first entered, the projection thereon is in, and
Blides up, the first vertical groove until the said projection is even with the hori-
zontal groove, the "calk is then rotated, until the said projection is even with
the bottom of the second vertical groove-the second vertical groove not being in
the same plane with the first vertical groove the calk is then forced upwards
with the said projection, in the said second vertical groove until the calk is
firmly secured in its proper position It is obvious that the "calk," made and
fitted to, or fixed in, the shoe as above described cannot turn round when in the
proper position, or easily work loose, as is the case with interchangeable calks of
other descriptions.
The shank of the calk can be of a regular taper, or as a modification may be
partly taper, and partly parallel, and may have two projections entering (firstly)
two vertical grooves, be rotated in a horizontal groove (for instance one fourth
part of a revolution) entering (secondly) two vertical grooves, in which position
the "calk" is forced home to its ultimate position

by the said Edward Edwards Hewett in the Great Seal Patent Office on the
14th April 1883.
EDWARD EDWARDS HEWETT of Sheffield in the County of York Consulting
Engineer of the London and Provincial Patent Agency "IMPROVEMENTS IN HORSE-
SHOES AND SHOES FOR OTHER ANIMALS, & communication to me the said Edward
Edwards Hewett from abroad by A. Gauer of Hamburg in the German Empire
This Invention relates to Improvements in borse-shoes and shoes for other
animals and to those descriptions of Shoes in which the calks, toe-pieces, or other
similar projections, are removable and changeable.
This Invention consists of an improved construction of shoe and removable calks
(or other similar projections) in which the calk has a tapered shank or stem with
one or more projections, pins or keys at right angles or otherwise to the longitudinal
centre line of the shank or stem; the hole in the shoe to receive the calk-is of a
form corresponding to that of the shank of the calk and it has two vertical and
one horizontal key-ways grooves or recesses so arranged as that when the shank
of the calk is first entered the projection thereon is in and slides up the first vertical
groove until the said projection is even with the horizontal groove, the calk is then
rotated until the said projection is even with the bottom of the second vertical
groove the second vertical groove not being in the same plane with the first
vertical groove-the calk is then forced upward with the said projection in the
said second vertical groove until the calk is firmly secured in its proper position.
It is obvious that the calks made and fitted to, or fixed in the shoe as above
described cannot turn round when in their proper positions or easily work loose as
is the case with interchangeable calks of other descriptions.
The shank of the calk can be of a regular taper or as a modification may be
partly taper and partly parrallel and may have two projections entering (firstly) two
vertical grooves be rotated (for instance one fourth part of a revolution) in a
horizontal groove entering (secondly) two vertical grooves in which position the
calk is forced home to its ultimate position.
The accompanying drawings illustrate this Invention.
Figure 1 is a plan or top view of the shoe; Figure 2 is an underneath view
thereof with the calks and toe-piece in section as taken on the line Y Z Figure 3;
Figure 3 is a back end view in elevation of the shoe; Figure 4 is a longitudinal
section of part of the shoe as taken through the dotted line X Y Figure 1; Figure 5
is a transverse section in elevation of part of the shoe as taken through the dotted
line WV Figure 1; Figure 6 is a side view, Figure 7 is a front view, and Figure 8
is a plan or top view of one of the calks.
A is the shoe, B B are the calks, C is the toe-piece, D is the pin or projection on
the stem of the calk or toe piece, e is the horizontal groove in the hole, f is the first
vertical groove, and g is the second vertical groove. In fixing the calks B B and
toe-piece C into the shoe A, they are entered into the holes in the shoe with the
pin D in the bottom or first vertical groove f, until the pin D is even with the
horizontal groove e; the calk B is then rotated until the said pin D is even with
the top or second vertical groove g in which position the calk B is driven home to
its ultimate position.
It is obvious that the projection can be in the hole in the shoe A and the grooves
in the stem or shank of the calk B or C, but I prefer to construct the shoe and calk
as above specified.
Having now described and particularly ascertained the nature and object of
the said Invention (communicated to me from abroad by A Gauer of Hamburg in

page_text: the German Empire) and the manner in which the same is or may be used or
carried into effect I would observe in conclusion that what I consider to be novel
and original and therefore claim as the Invention secured to me by the herein-
before in part recited Letters Patent is :-
=
Improvements in horse-shoes and shoes for other Animals by the construction of
interchangeable calks and toe-pieces with pins or projections on the stems thereof
and the holes in the shoe (to receive the said calks and toe pieces) with two vertical
grooves (the two vertical grooves not being in the same plane) and one horizontal
groove for the purpose of securing the calks and toe pieces in the shoe substantially
as herein before specified and as described in reference to the accompanying
drawings.
In witness whereof I the said Edward Edwards Hewett have hereunto set my
hand and seal this Twelfth day of April in the year of our Lord one
thousand eight hundred and eighty three.
EDWARD EDWARDS HEWETT (L.S.)
