IMPROVEMENTS IN APPARATUS USED FOR BREAKING HORSES, AND KNOWN AS DUMB JOCKEYS
Year: 1864

page_text: LETTERS PATENT to Samuel Blackwell, of 259, Oxford Street, in the
County of Middlesex, Saddler, for the Invention of "IMPROVEMENTS IN
APPARATUS USED FOR BREAKING HORSES, AND KNOWN AS DUMB JOCKEYS."
Sealed the 20th May 1864, and dated the 9th March 1864.
PROVISIONAL SPECIFICATION left by the said Samuel Blackwell at the
Office of the Commissioners of Patents, with his Petition, on the
9th March 1864.
I, SAMUEL BLACKWELL, of 259, Oxford Street, in the County of Middlesex,
Saddler, do hereby declare the nature of the Invention for "IMPROVEMENTS IN
APPARATUS USED FOR BREAKING HORSES, AND KNOWN AS DUMB JOCKEYS," to be as
follows:-
This Invention has for its object improvements in apparatus used for
breaking horses, and known as dumb jockeys. Heretofore, in the manu-
facture of dumb jockeys according to an Invention described in the Speci-
fication of a Patent granted to me on the 9th day of March, 1853, No. 595,
gutta percha has been used either alone or combined with wood, leather, or
metal. Now my present Invention consists in forming the horns or upper
parts of a dumb jockey of gutta percha or of gutta percha compounds, each
horn having enclosed therein a piece or pieces of whalebone in order that
whilst retaining the advantages derived from the use of gutta percha, the
horns may be made of greater strength and elasticity, and the horns of a
dumb jockey thus rendered less liable to be injuriously acted on by extreme
temperatures.

by the said Samuel Blackwell in the Great Seal Patent Office on the 8th
September 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
BLACKWELL, of 259, Oxford Street, in the County of Middlesex, Saddler,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of March, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Samuel Blackwell, Her special licence that I, the said Samuel
Blackwell, my executors, administrators, and assigns, or such others as I, the
said Samuel Blackwell, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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 "IMPROVE-
MENTS IN APPARATUS USED FOR BREAKING HORSES AND KNOWN AS DUMB JOCKEYS,"
upon the condition (amongst others) that I, the said Samuel Blackwell, 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 Samuel Blackwell, 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):
This Invention has for its object improvements in apparatus used for
breaking horses, and known as dumb jockeys. Heretofore, in the manu-
facture of dumb jockeys, according to an Invention described in the Specifi-
cation of a Patent granted to me on the 9th day of March, 1858, No. 595,
gutta percha has been used either alone or combined with wood, leather, or
metal. Now, my present Invention consists in forming the horns or upper
parts of a dumb jockey of gutta percha or of gutta percha compounds, each
horn having inclosed therein a piece or pieces of whalebone, in order that
whilst retaining the advantages derived from the use of gutta percha, the

page_text: horns may be made of greater strength and elasticity, and the horns of a
dumb jockey thus rendered less liable to be injuriously acted on by extreme
temperatures.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a dumb jockey of the form preferred. Heretofore, in con-
structing such jockeys, it has been usual to employ all gutta percha or gutta
percha compounds in making all the parts thereof. Figure 2 shows a section
of one of the horns and of the part of the jockey from which the horn springs,
and with which the horn is connected, and is made in one part therewith.
This horn is, with the exception of the whalebone imbedded or introduced
therein, to be made by preference all of gutta percha, but india-rubber,
ground leather, or vegetable or animal fibres or other matters may be inti-
mately mixed with the gutta percha in like manner to that in which such like
foreign matters have heretofore been mixed with gutta percha.
In moulding or forming each horn of a dumb jockey of gutta percha or of
gutta percha compounds, one or more pieces of whalebone is or are imbedded
or inclosed therein, as shown at a, a, which is readily done when the gutta
percha or its compound is plastic, so that such whalebone may enter into and
form part of the body or part of the jockey, and thus give greater strength
to the root or part of the horn where it joins such body or part of the
jockey.
The Drawing shows the forms it is preferred to give to the several parts of
a dumb jockey, but the forms of the parts may if desired be varied.
In witness whereof, I, the said Samuel Blackwell, have hereunto set
my hand and seal, this Seventeenth day of August, in the year of
our Lord One thousand eight hundred and sixty-four.
