IMPROVEMENTS IN HORSESHOES
Year: 1841

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
VAUX, of Frederick Street, Gray's Inn Road, in the County of Middlesex,
Land Surveyor, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Nineteenth day of January, in the fourth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said
Thomas Vaux, Her especial licence, full power, sole privilege and authority,.
that I, the said Thomas Vaux, my exors, adiñňors, and. assigns, or such
others as I, the said Thomas Vaux, my exors, adñiors, or assigns, should
at any time agree with, and no others, from time to time and at all times
during the term of years therein expressed, should and lawfully might make,
use, exercise, and vend within England, Wales, and the Town of Berwick-
upon-Tweed, my Invention of "IMPROVEMENTS IN HORSESHOES;" in which said
Letters Patent is contained a proviso that I, the said Thomas Vaux, should
cause a particular description of the nature of my said Invention, and in what
manner the same is to be performed, to be enrolled in Her said Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said in part recited Letters Patent, as in and by the
same, reference being-thereunto had, will more fully and at large appear..

page_text: NOW KNOW YE, that in compliance with the said proviso, I,. the
said Thomas Vaux, do hereby declare the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had to
the Drawings hereunto annexed, and to the figures and letters marked thereon,
(that is to say)-
My Invention relates to a mode of constructing horseshoes with moveable
caukings or projections, in order that the shoes may be "roughed" and
unrongbed with more facility when required, and without taking off the shoes.
And in order that my Invention may be most fully described and readily carried
into effect, I will proceed to describe the Drawings hereunto annexed, in the
various Figures of which the same letters are used to indicate the same
parts.
Figure 1 represents a plan of a shoe constructed according to my Invention.
Figure 2 is a side edge view, and Figure 3 is a back edge view thereof.
Figure 4 shews a plan of the shoe separately, and Figure 5 shows the various
views of the cauks or projections used in roughing the shoe. a, a, represents
the shoe; b is a dovetail groove in front, which receives the cauk or projec-
tion 6', the nature of which is clearly shewn in the Drawing, and when in
the dovetail groove the projection is securely retained by a screw c; at the
hinder parts of the shoe there are dovetail grooves d, d, which receive the
projections e, e, and the same are securely held by means of pins or screws f,f
which are driven into holes formed at the back of the shoe and bent over at
the points, as shewn. Figure 6 shews a plan of another shoe. Figure 7
is an edge view in section, and Fig. 8 is a back view thereof; Figure 9 being
a plan of the shoe separately, and and Figure 10 shows various views of the
parts employed for roughing the shoe. In this arrangement the mode of
constructing and affixing the projection in front of the shoe is somewhat
varied; for it will be seen that in place of fixing the same by a screw, as in
the former case, there is a wedge g driven in at the back into suitable grooves,
formed in the shoe, as shewn, and a pin h is driven through the wedge and
through the dovetail plate on which the projection is formed, and is clenched
in front, as is clearly shewn in the Drawing. Figure 10 shews a plan of
another shoe, having two projections in front fixed by screws in a similar
manner to that shewn in Figure 1. Figure 12 shews a plan of the shoe
without the projections. It will be evident that the projections so applied,
owing to the dovetail form of the grooves in the shoes and the manner of
fixing the projections therein, that the same will be most secure when in use;
and in order to give strength to the shoe at the parts where the grooves are

page_text: formed, I recommend that those parts should be somewhat thicker, as is
shown. In making shoes according to my Invention, I make them by cast-
ing in malleable cast iron, taking care to cast them with great accuracy, so
that the grooves may not require the use of a file or other instrument; and I
also make the parts with the projections of malleable cast iron, by casting the
same, and it will be found that in making the sand mould for casting the
various parts, that if well and accurately formed models of the parts made of
brass be used, the castings produced will fit, requiring very little, if any, use
of a file or other tool; and the various parts being thus cast they are to be
annealed for seven or ten days, according to the substance of the metal to bo
operated upon, as is well understood in working malleable cast iron. The
holes for the screws and for the pins h are to be drilled or produced in cast-
ing, and those for screws are to be tapped to suit the screws to be received.
I would remark that although I prefer to use malleable cast iron, I do not
confine myself thereto, as shoes may be made by forging wrought iron into
the forms shown.
Having thus described the nature of my Invention and the manner of
performing the same, I would have it understood that what I claim is,-
First, tho mode of constructing shoes of malleable cast iron with dovetail
grooves and moveable projections, as described;
Secondly, I claim the mode of making shoes of wrought iron with dovetail
grooves and moveable projections, as above described.
In witness whereof, I, the said Thomas Vaux, have hereunto set my
hand and seal, this Nineteenth day of July, in the year of our Lord
One thousand eight hundred and forty-one.
Inrolled the Nineteenth day of July, in the year of our Lord One
thousand eight hundred and forty-one.
