PROVISIONAL SPECIFICATION left by the said Matthew Augustus
Soul at the Office of the Commissioners of Patents, with his
Petition, on the 12th December 1872.
I, MATTHEW AUGUSTUS SOUL, of No. 6, Southampton Buildings,
5 Holborn, in the County of Middlesex, Consulting Engineer and Patent
Agent, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY OR APPARATUS, FOR BORING ROCKS AND SUCH LIKE HARD
SUBSTANCES," a communication to me from abroad by Martin Neuerburg,

page_text: of the Machine Manufacturing Company "Humbold," late Sievers
and Co., of Kalk, near Cologne, in the Empire of Germany, to be as
follows:-
This Invention consists in a peculiar arrangement of mechanism for
rock boring machines for the purposes, firstly, of guiding the piston;
secondly, of turning the borer; and thirdly, of feeding forward the
borer in proportion to its penetration of the rock or similar hard
substance.
The nature of this Invention will be best understood by reference to
the Drawings accompanying this Provisional Specification.
n
I. A, A, is a cylinder in which a piston B moves; this piston has on
one end a thick rod B¹, on the other a thinner one B". Both of
these rods go air-tight, the one through the bottom and the other
through the cover of the cylinder. On the end of the thick rod the
boring chisel C is fixed by means of wedges. The end of the rod B"
carries a ring c together with a turning joint c¹; this ring turns slightly
round the rod and is kept in position by the nut d. Gearing together
with the turning joint c¹ is a rod D, whose opposite end goes through a
long box E; this box constitutes one end of a lever of the first order
fastened on an axis E¹, and whose other arm El gears with a slot of
the valve rod F. The valve rod F encompasses the three ported slide
valve F' which covers the air channels f,f¹, f", in the cylinder A. The
compressed air or the steam which is to set the machine working is
conducted by the tube G and the cock H, and comes through the
channel funder the steam distributor F", and from thence through the
channel f¹ behind the piston B, pushing the same forward. By this the
rod D in the box E is moved, and the axis E¹ turned round a certain
angle. The arm E" moves a part of its way without doing any work
in the slot of the valve rod F, and advances the slide towards the end of
the piston's stroke, so that it is placed upon the channels ff, ƒ“, and
reverses the piston. The fresh air or the steam now will stream through
the channel before the piston and throw it back, while the air first
used goes back through the channel f' and escapes through the open
valve chest. When the piston returns towards the end of the stroke
the steam distributor is put in the former position as represented in the
Drawing, and thus the working of the piston begins anew.
2. The thinner rod B" goes through a box J, which is adjusted air-tight
in the cover of the cylinder, and can turn in it. In this box there is a

page_text: salient wedge i adapted to a furrow grooved along the rod. On the
box Ja ratchet wheel K with small teeth is fixed. At one end of the
axis E¹ there is a short lever L; it gears with a rod I led in a straight
line by two guides 1, 1. On the rod L' is fixed a catch M gearing with
the wheel K, and pushing it forward at every stroke of the piston one
or more teeth. The wheel K is prevented from turning in the opposite
direction by the paul N. By the rotation of the wheel K the rod B",
and therewith the borer, is turned by jerks backward at every stroke of
the piston.
3. On the rod L' there is a second catch M³ gearing with a wheel K'
fixed upon a box m, m, whose inside is provided with a worm of a screw;
this box is the nut of a screw O, O, which with the spindle (screw) O¹, O¹,
constitute a frame connected at its ends by cross pieces, on which the
cylinder rests by means of the four pieces a, a, a, a. One of these
pieces a is placed round the box m, m. By turning this latter the
cylinder A, A, moves along the screwed spindles O¹, O'. Now the ratchet
wheel K being so divided that one tooth exactly corrresponds to one
full stroke of the piston, the catch M' will turn the wheel K' only when
the piston goes the whole length of its stroke. As long therefore as the
borer does not pierce the rock, the cylinder A of the machine is not
moved, but kept at rest; but upon the borer entering the rock, the
cylinder is moved after it in the same proportion as the borer penetrates
the rock.

"IMPROVEMENTS IN MACHINERY OR APPARATUS FOR BORING ROCKS AND SUCH LIKE
HARD SUBSTANCES," a communication to me from abroad by Martin Neuer-
burg, of the Machine Manufacturing Company "Humbold," late Sicvers
and Co., of Kalk, near Cologne, in the Empire of Germany, upon the
condition (amongst others) that I, the said Matthew Augustus Soul, my
exccutors 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 imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Matthew Augustus Soul, 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, reference being had to the accompanying
Drawings, that is to say :-
This Invention consists of a peculiar arrangement of mechanism for
boring rocks and such like hard substances for the purposes, firstly, of
guiding the piston; secondly, of turning the borer; and thirdly, of
feeding forward the borer in proportion to its penetration of the rock or
similar hard substance to be bored.
The nature of this Invention will be distinctly understood by reference
to the accompanying Drawings, and the following description read in
connection therewith..
I. A, A, is a cylinder in which a piston B moves; this piston has on
one end a thick rod B¹, on the other a thinner one B", the one through
the bottom and the other through the cover of the cylinder. On the

page_text: further or outer end of the thick rod B¹; the boring chisel c is fixed by
means of wedges. The outer end of the rod B" carries a ring c, together
with a turning joint c¹; this ring turns slightly round the rod and is
kept in position by the nut d. Gearing together with the turning
joint c' is a rod D, whose opposite end goes through a long box E; this
box constitutes one end of a lever of the first order fastened on an axis E¹,
and whose other arm E gears with a slot of the valve rod F. The valve
rod F encompasses the three-ported slide valve F¹, which covers the air
channels fff", in the cylinder A. The compressed air or the steam,
which is to set the machine working, is conducted by the tube G and
cock H, and comes through the channel f under the steam or air dis-
tributor F, and from thence through the channel f¹ behind the piston B,
pushing the same forward. By this the rod D in the box E is moved,
and the axis E turned round a certain angle. The arm E" moves a
part of its way without doing any work in the slot of the valve rod F,
and advances the slide towards the end of the piston's stroke, so that it
is placed upon the channels f,f,f", and reverses the piston. The fresh
air or the steam will now stream through the channel f", before the
piston and throw it back, while the air or steam first used goes back
through the channel f¹ and escapes through the open valve chest. When
the piston returns towards the end of the stroke, the steam distributor
is put in the former position, as represented in the Drawing, and thus the
working of the piston begins anew.
II. The thinner rod B₁ goes through a box. J, which is adjusted air-
tight in the cover of the cylinder, and can turn in it. In this box
there is a salient wedge i adapted to a furrow grooved along the rod.
On the box Ja ratchet wheel K with small teeth is fixed. At one end
of the axis Et is a short lever L; it gears with a rod led in a straight
line by two guides 1, 1. On the rod L is fixed a catch M gearing with
the wheel K, and pushing it forward at every stroke of the piston one or
more teeth. The wheel K is prevented from turning in the opposite
direction by the paul N. By the rotation of the wheel K, the rod B",
and therewith the borer is turned by jerks backward at every stroke of
the piston.
III. On the rod I there is a second catch M¹ gearing with a ratchet
wheel K¹ fixed upon a box m, m, provided internally with the worm of a
screw; this box is the nut of a screw O, O, which with the spindle O¹, O³,
constitute a frame connected at its ends by cross pieces upon which the

page_text: cylinder rests by means of the pieces a, a, a, a. One of these pieces a
is placed round the box m, m. By turning this latter the cylinder A, A,
moves along the screwed spindles O¹, O¹. Now the ratchet wheel K¹
being so divided that one tooth exactly corresponds to one full stroke of
the piston, the catch M' will turn the wheel K¹ only when the piston
goes the whole length of its stroke. As long therefore as the borer does
not pierce the rock, the cylinder A of the machine does not travel but
is kept at rest; but upon the borer entering the rock the cylinder is
moved after it in the same proportion as the borer penetrates the
rock
