Year: 1873

page_text: LETTERS PATENT to John Patterson, of Belfast, in the County of
Antrim, Merchant Banker, for the Invention of "IMPROVEMENTS IN
MACHINERY FOR BORING ROCKS AND OTHER HARD SUBSTANCES."
Sealed the 9th April 1874, and dated the 20th October 1873.
PROVISIONAL SPECIFICATION left by the said John Patterson at the
Office of the Commissioners of Patents, with his Petition, on the
20th October 1873.
I, JOHN PATTERSON, of Belfast, in the County of Antrim, Merchant
Banker, do hereby declare the nature of the said Invention for " IM-
PROVEMENTS IN MACHINERY FOR BORING ROCKS AND OTHER HARD SUBSTANCES," to
be as follows:-
―
My Invention consists in applying the machinery for hammering, for
which Letters Patent were granted to Alfred Vincent Newton on the
24th day of March 1866, No. 872, to impart the requisite motion to the
drills of boring machines, whereby the rocks or other hard substances
are bored more expeditiously and perfectly than heretofore. The drills
are attached to the springs with flexible connections described in the
said Patent, and motion is communicated to the driving shaft of the

page_text: boring machine by means of a small water engine, ram, or wheel driven
by the water, so abundant in mines and cuttings, or the arrangements
may be modified so as to allow the application of compressed air or
steam, or other motive power as circumstances may require.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said John Patterson in the Great Seal Patent Office on
the 17th April 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
PATTERSON, of Belfast, in the County of Antrim, Merchant Banker,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of October, in the year of
our Lord One thousand eight hundred and seventy-three, in the thirty-
seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John Patterson, Her special licence that
I, the said John Patterson, my executors, administrators, and assigns,
or such others as I, the said John Patterson, my executors, adminis-
trators, 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 "IMPROVEMENTS IN MACHINERY
FOR BORING ROCKS AND OTHER HARD SUBSTANCES," upon the condition
(amongst others) that I, the said John Patterson, my executors or
administrators, by an instrument in writing under my, or their, or one
of their hand 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 John Patterson, do hereby declare the
nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, that is to say :-
My Invention consists in applying the machinery for hammering, for

page_text: which Letters Patent were granted to Alfred Vincent Newton, on the
Twenty-fourth day of March One thousand eight hundred and sixty-six,
No. 872, to impart the requisite motion to the drills of boring machines,
whereby rocks or other hard substances are bored more expeditiously
and economically than heretofore, and which said machinery may be
operated by means of a small water engine, ram, or wheel driven by the
water so abundant in mines or cuttings, or the arrangements may bo
modified so as to allow the application of compressed air or steam, or
other motive power as circumstances may require.
And in order that my Invention may be fully understood and readily
carried into operation, I will proceed to describe the two accompanying
Sheets of Drawings, reference being had to the letters and figures
marked thereon, corresponding letters of reference indicating similar parts.
Figure 1 (Sheet 1) is a side view, and Figure 2, a front elevation of my
machine when working in a vertical position, but by changing the
position of the stays or supports, the boring or drilling can be effected at
various angles as may suit the requirements of the miner. In these
views A, A, represent two parallel standards having their upper ends
fitting into and supporting the cross head C, while at their lower ends
they are held in position by the cross bar D, and are furnished with
adjustable steel points a¹, a¹, to suit the inequalities of the ground.
B, B, are adjustable stays or supports also attached by universal joints
b¹, b¹, to the cross head C, and are retained in position by means of the tie
rod F and the tie bars E, which latter are attached by universal joints e¹
to the cross bar D. G is a portable wooden platform on which the
workman stands when operating the machine, the addition of his own
weight greatly increasing its stability and raising him to the desired
height for working it. H is a cast-iron moveable carriage which is made
to traverse upwards and downwards on the two parallel guides or
standards A, A, by means of the screw or feeding rod J working in the
nut J¹, such screw or feeding bar being supported in its position by the
cross head C and the cross bar D. The driving shaft L with internal spur
wheel M which drives the spur pinion N, are supported by the carriage
H, and set in motion by means of the two handles O, O. The spring P
which carries the drill holder Q on its flexible connection V, is connected
through the sliding block R to the crank S, which crank when operated
moves the piston or spring holder T in a direction parallel, or in tho
same straight line or direction as the boring bar or drill, which boring

page_text: bar or drill is fixed by means of a tightening pin into the socket q' of
the holder Q.
A partial rotary motion is given to the drill holder Q by the arrange-
ment shewn in Figures 3, 4, 5, and 6, which consists in the stem of the
said drill holder being forged in a rectilineal form (midway between the
head v¹ and the socket holder q³), and twisted as shewn at h¹, Figure 5,
so that when sliding through the opening of corresponding form in the
centre of the ratchet wheel W, the holder and drill U are partially made
to rotate after each blow, and any backward revolution of the ratchet
wheel W is prevented by means of the spring pawl w', see Figure 6,
which is a sectional view through the line A¹, B¹, of Figure 1.
..
Figure 7 represents a plan of the machine with the stays or supports
B in a horizontal position.
Figure 8 is a sectional view through the line C¹, D¹, of Figure 1,
while Figure 9 is a sectional view of the adjustable steel points a¹, a¹.
.
.
The mode of operation is as follows:-One or more workmen place
themselves on the wooden platform G, and by turning the handles O, O,
cause the crank or cam`shaft S to rotate, thereby moving the piston or
spring holder T in a backward or forward direction, carrying with it
the spring P and the drill holder Q, giving to the latter a rapid hammering
action with rotative motion, and by this means penetrating the rock or
other substance operated upon.
My Invention may be modified by dispensing with the crank shaft S,
and applying steam or compressed air to actuate the piston T and
spring P.
When employing water as the motive power, the handles O, O, can
be removed, and a small water wheel M employed as shewn at Figure 10,
(Sheet 2), where a represents a water tank or accumulator fixed at a
sufficient elevation from the surface of the mine to give the requisite
power to drive the machines at any distance below ground; b is the
induction or supply pipe for carrying the water through the stop-cock c
and flexible tube d to the water wheel M, where after having performed
its work it is conveyed by its own gravitation through the flexible
tube fand the eduction or delivery pipe e into a reserve cistern or tank
above ground, where by the action of a small steam engine it is again
pumped into the accumulator a, and thus the same water is used over
and over again.

page_text: In the event of driving by means of water and elevated accumulator a
as shown at Fig. 10, the small steam engine above-named may be
economically made to supply ample power to drive any number of borers
or drills as well as water wheels or rams for hauling or other purposes
by its being constantly kept at work pumping water into the accumulator
a, whereas if a more powerful engine were employed for directly driving
the borer, it would be kept idle during a great portion of the time, while
the bore holes were being charged and blasted, and the debris removed. Or
the water may be allowed to escape after having passed through or over
the water wheel M into the well of the mine, where it can be pumped
into the reserve cistern or tank on the surface by means of the pumping
appliances usually found in mines of any magnitude or extent, and from
thence conveyed by means of the induction or supply pipes 6 to the
water wheel M, thereby imparting the necessary driving power without
the assistance of any additional plant or machinery.
The wheel M need not necessarily be driven by water, but by a belt
in connection with steam, or otherwise by compressed air.
Having thus stated the nature of my Invention, and the manner
in which the same is to be performed, I claim under the above recited
Letters Patent, the application of metal springs, or elastic or other
flexible connection between the crank or cam driving shaft, or the steam
or compressed air piston and the boring bar or drill, and the application
of water power for driving the said boring bar or drill in the manner
described.
In witness whereof, I, the said John Patterson, have hereunto set
my hand and seal, this Eleventh day of April in the year of our
Lord One thousand eight hundred and seventy-four.
