IMPROVEMENTS IN MACHINERY EMPLOYED IN GETTING GOALS. STONE. AND OTHER MINERALS."
Year: 1864

page_text: LETTERS PATENT to James Grafton Jones, of Blaina Iron Works, Mon-
mouthshire, for the Invention of "IMPROVEMENTS IN MACHINERY EMPLOYED
IN GETTING GOALS. STONE. AND OTHER MINERALS."
PROVISIONAL SPECIFICATION left by the said James Grafton Jones at
the Office of the Commissioners of Patents, with his Petition, on the
21st October 1864.
I, JAMES GRAFTON JONES, of Blaiņa Iron Works, Monmouthshire, do hereby
declare the nature of the Invention for "IMPROVEMENTS IN MACHINERY EMPLOYED
IN GETTING COALS, STONE, AND OTHER MINERALS," to be as follows:-
This Invention has for its object improvements in machinery employed, in
getting coals, stone, and other minerals.
In working, picks mounted on carriages on railways or trams when actuated
by power, it is found, particularly when performing that part of the work
known as "holeing" or undercutting, that there is a tendency to cause the
carriage and machinery to swerve and vibrate on the rails to the prejudice. of
the way. Now this Invention consists in the application of a rolling weight
or roller at the hinder part of the carriage. This roller or weight runs on the
rails, and is formed with flanges to keep it correctly on the rails. The roller
or rolling weight is connected with the under part of the carriage by a bar in
a central position between the rails of the way on which the carriage runs.
This bar is made in two parts in order that its length and the distance of the
roller from the front of the carriage may be adjusted. The fore end of this

page_text: bar is securely and rigidly fixed by screw bolts and nuts to the under part of
the carriage. The axis of the roller turns in a single bearing which is equi-
distant from the two ends of the roller.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said James Grafton Jones in the Great Seal Patent Office ou
the 21st April 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
GRAFTON JONES, of Blaina Iron Works, Monmouthshire, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of October, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said James Grafton Jones, Her special licence that I, the said James
Grafton Jones, my executors, administrators, and assigns, or such others as 1,
the said James Grafton Jones, my executors, administrators, and assigns,
should at any time agree 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 "IMPROVE-
MENTS IN MACHINERY EMPLOYED IN GETTING COALS, STONE, AND OTHER MINERALS,"
upon the condition (amongst others) that I, the said James Grafton Jones, my
executors or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, should particularly describe and ascer-
tain 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 James Grafton Jones, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, 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 machinery employed in
getting coals, stone, and other minerals.
In working picks mounted on carriages on railways or trams when actuated
by power, it is found, particularly when performing that part of the work
known as "holeing" or undercutting, that there is a tendency to cause the

page_text: carriage and machinery to swerve and vibrate on the rails to the prejudice of
the way. Now this Invention consists in the application of a rolling weight or
roller at the hinder part of the carriage. This roller or weight runs on the
rails, and is formed with flanges to keep it correctly on the rails. The roller
or rolling weight is connected with the under part of the carriage by a bar in
a central position between the rails of the way on which the carriage runs.
This bar is made in two parts in order that its length and the distance of the
roller from the front of the carriage may be adjusted. The fore end of this
bar is securely and rigidly fixed by screw bolts and nuts to the under part of
the carriage. The axis of the roller turns in a single bearing which is equi-
distant from the two ends of the roller.
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 is a side elevation partly in section, and Figure 2 a plan of
apparatus applied to a carriage employed in getting coals or minerals.
a is a bar which is formed in two parts, which are connected by screw
bolts and nuts, and as one of the parts is slotted, the length of the bar
between the carriage to which its fore end is fixed and the roller b at the
hinder end may be adjusted; c is the hinder part of a carriage such as is now
used to carry picks or cutting instruments for getting coal or mineral. The
bar at its fore end is fixed rigidly to the hinder part of the carriage; this is
shown in the Drawings to be by means of screw bolts and nuts, but such
means of fixing may be varied. On the bar is fixed a platform d for the
workman or for other uses.
Ilaving thus described the nature of my Invention, and the manner of per-
forming the same, I would have it understood that I claim the application of
apparatus such as is herein described to a carriage arranged for carrying
picks or cutting instruments used in getting coals and minerals.
In witness whereof, I, the said James Grafton Jones, have hereunto
set my hand and seal, this Nineteenth day of April, in the year
of our Lord One thousand eight hundred and sixty-five.
J. GRAFTON JONES. (L.S.)
