LETTERS PATENT to Henry Charlton, of Birmingham, in the County of
Warwick, Merchant and Manufacturer, for the Invention of "IMPROVE-
MANUFACTURE OF CERTAIN KINDS or SHORE FOR MULES AND
HORSES."
Sealed the 13th June 1862, and dated the 11th January 1862.
PROVISIONAL SPECIFICATION left by the said Henry Charlton at the
Office of the Commissioners of Patents, with his Petition, on the 11th
January 1862.
I, HENRY CHARLTON, of Birmingham, in the County of Warwick, Merchant
and Manufacturer, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN THE MANUFACTURE OF CERTAIN KINDS OF SHOES FOR MULES.
AND HORSES," to be as follows:-
My Invention relates to the manufacture of shoes of the kind generally
used in South America for mules and horses, employed for transporting
merchandize, which shoes have a sharp outer edge, and have large headed
nails driven in them, for the purpose of giving the animal's feet a firmer hold
on the surface he has to walk over, than would be afforded by ordinary.
horse-shoes.
In manufacturing the said shoes according to my Invention, I roll the iron
of which the said shoes are made in nearly flat bars, but on that part of the
iron which in the finished shoe constitutes the outer edge, on the upper side I

page_text: make a rib or projection of about one-eighth of an inch deep, the said pro-
jection being sharp at its summit, and widening on one side at its base. That
side of the bar of iron which in the finished shoe constitutes the under
side is not quite flat, but is bevilled off towards the outer edge. In
making the large rectangular holes in which the before-mentioned large nails
are driven, I employ a pair of dies or cutting tools, whereby the whole or more
than one of the said holes may be cut out at one operation, instead of cutting
or piercing them singly; I work the said cutting tools, by a hydraulic or other
direct acting press. The iron of the shape described and cut into the required
lengths, is bent or fashioned into shoes in the ordinary manner. The rolls
and cutting tools and presses which I employ resemble those ordinarily
employed for like purposes, but have the forms and the strength required to
fit them for the purposes to which I apply them.
The essence of my Invention consists in shaping and in making the bar
iron from which shoes of the kind described are manufactured by rolling,
instead of making the said iron by hand forging as is ordinarily practised, and
cutting or piercing the whole of the rectangular holes or more than one of
them in the said iron at one operation by the use of a direct-acting press.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Charlton in the Great Seal Patent Office on the
2nd July 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
CHARLTON, of Birmingham, in the County of Warwick, Merchant and
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by. Her Letters
Patent, bearing date the Eleventh day of January, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Henry Charlton, Her special licence, that I, the said Henry Charlton, my
executors, administrators, and assigns, or such others as I, the said Henry
Charlton, my executors, administrators, and assigns, should at any time agreo
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN THE MANU-
FACTURE OF CERTAIN KINDS OF SHOES FOR MULES AND HORSES," upon the condition

page_text: (amongst others) that I, the said Henry Charlton, my executors or administrators,
by an instrument in writing, under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Invention,
and in what manner the same was to be performed, and cause the same to be
filed in the Great Seal Patent Office within six calendar months next and
immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Henry Charlton, do hereby declare the
nature of the said Invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement
thereof, that is to say:-
My Invention relates to the manufacture of shoes of the kind generally
used in South America, particularly in Brazil, for mules and horses employed
for transporting merchandise, which shoes have a sharp outer edge, and have
large headed nails driven in them for the purpose of giving the animal's feet
a firmer hold on the surface he has to walk over than would be afforded by
ordinary horse-shoes.
My said Invention consists in shaping by rolling bar iron from which shoes
of the kind described are manufactured, instead of shaping the said iron by
hand forging as is ordinarily practised, and cutting or piercing the whole of the
rectangular holes, or more than one of them, in the partially made shoes at
one operation by the use of a direct-acting press, as herein-after described and
illustrated in the accompanying Drawing.
In manufacturing the said shoes according to my Invention, I roll the iron
of which the said shoes are made in nearly flat bars, but on that part of the
iron which in the finished shoe constitutes the outer edge on the upper side,
I make a rib or projection of about one-eighth of an inch deep, the said pro-
jection being sharp at its summit, and widening at its base. That side of the
bar of iron which in the finished shoe constitutes the under side is not quite
flat, but is bevilled off towards the outer edge.
Figure 1 of the accompanying Drawing represents in elevation a piece of
bar iron rolled of the shape described; Figure 2 is an end elevation of the
same; and Figure 3 is an edge view of the same. The rib or projection on
the outer edge of the said iron is marked a, the shape of which rib or projec-
tion will be understood by an examination of the Drawing, and the bevilled
edge at the opposite side of the said iron is marked b. I make the bar iron
having the shape represented by passing heated plain bars of iron through
rolls, the grooves in which rolls have the shape of the iron to be made. The
rolls which I employ for rolling the said iron do not differ in any essential
respect from rolls used for rolling iron for other purposes, and I therefore do

page_text: not consider it necessary either to describe or to represent the said rolls. The
iron rolled of the shape represented is cut into the required lengths, and the
said lengths of iron are bent or fashioned into shoes in the ordinary manner.
Figure 4 represents in plan the upper side of a shoe made from the bar of
iron, Figures 1, 2, and 3; Figure 5 is an edge view of the same; and
Figure 6 is a vertical section of the same. In the finished shoe, Figures 4,
5, and 6, the rib or projection on the outer edge of the upper side of the said
shoe is marked a, and the bevil on the opposite edge and under side of the
shoe is marked b. After the iron has been bent or fashioned into a shoe, the
said shoe is finished by making in the flat part-c the large rectangular holes
d, d; in which holes large headed nails are driven, by-which the shoes-are
secured to the animal's feet.
In making the said rectangular holes 'd, d, in the shoes, "I employ a pair of
lies or cutting tools, whereby the whole of the holes, or more than one of
them, are cut out at one operation, instead of cutting them singly; I prefer to
cut out the whole of the said holes at once, and I will describe and represent
a pair of dies or cutting tools which I use for that purpose.
Figure 7 represents a plan of the under side of the upper or moveable die
of the said pair of dies; and .Figure 8 is a vertical section of the same
taken through the line of Figure 7; Figure 9 is a plan of the upper side of
the lower or fixed die of the said pair of dies; and Figure 10 is a vertical.
section of the same taken through the line y of Figure 9. The upper or
moveable die e, Figures 7 and-8, is fixed to the ram of a bydraulic or other
direct-acting press of the ordinary kind, and the lower die if, Figures 9 and 10,
is fixed on the bed of the said. press. I fix in the upper die e, a series of
cutting or piercing tools g, g, by which tools the whole of the rectangular
holes in the shoe are cut at one operation. The said tools 9, 9, have the shape
which will be understood by an examination of Figures 7 and 8. In the
lower and fixed die f, I make a number of openings h, h, corresponding in
number with the cutting or piercing tools 9, 9, in the upper die e. The edge of
the lower die f bas a depression or recess i made in it, into which depression i
the rib or projection a of the shoe.fits. The shoe is placed on the lower die f
with its upper side downwards, the rib or projection a on the said upper side
engaging with the depression i in the edge of the said die. The upper die e
being brought down upon the shoe on the fixed die f, the whole of the holes
d, d, are cut or pierced in the said shoe at one operation, the shape of the
cutting or piercing tools g, g, making the said holes countersunk on the under-
side of the said shoe.
My improvement in cutting out or piercing the holes in the shoes may

page_text: be applied to shoes made from iron manufactured by hand forging in the
ordinary way.
Having now described the nature of my Invention, and the manner in which
the same is to be performed, I wish it to be understood that I claim as my
Invention,
Firstly, the improvement in the manufacture of those kinds of shoes for
mules and horses generally used in Brazil, herein-before described and illus-
trated in Figures 1, 2, 3, 4, 5, and 6 of the accompanying Drawing, that is
to say, shaping the bar iron from which the said shoes are manufactured, by
rolling, instead of making the said iron as has hitherto been practised.
Secondly, cutting or piercing at one operation the whole of the rectangular
holes, or more than one of them, in shoes of the kind before described by
means of dies or tools worked in a direct-acting press, as herein-before
described and illustrated in Figures 7, 8, 9, and 10, of the accompanying
Drawing.
In witness whereof, 1, the said Henry Charlton, have hereunto set my
hand and seal, this Twenty-eighth day of June in the year of our
Lord One thousand eight hundred and sixty-two.
Witness,
RICHARD SKERRETT,
Clerk to George Shaw,
Birmingham.
