page_text: 66, Chancery Lane, in the County of Middlesex, Civil Engineer, for the
Invention of "IMPROVED APPARATUS FOR BORING ROCKS AND OTHER MINERAL
SUBSTANCES."-A communication from abroad by Emanuel Lisbet, of
No. 45, Rue St. Sebastien, Paris, in the Empire of France.
Sealed the 9th May 1862, and dated the 31st December 1861.
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on the
31st December 1861.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Civil Engineer, do hereby declare the nature of
the said Invention for "IMPROVED APPARATUS FOR BORING ROCKS AND OTHER
MINERAL SUBSTANCES," to be as follows:-
This Invention of improved apparatus for boring rocks and other mineral
substances relates to the construction, arrangement, and mode of working the
perforating or boring tools or apparatus employed for boring holes in rocks for
mining or quarrying operations. The improved boring tools or apparatus may
be classed under two heads. In one arrangement apparatus for operating the
tools is provided with toothed or other gearing, and in the second arrangement
the toothed gearing is dispensed with. The first and more complete arrange-
ment consists of a rectangular frame, in the internal faces of which there are
two side grooves in which work the sides or arms of a moveable forked frame.
The arms of the moveable frame are provided with ratchet teeth, and the two

page_text: side pieces of the rectangular frame have notches made thereon, so as to
present the appearance of a double rack united at top and bottom by cross
pieces. The lower of these cross pieces carries a double projecting prong
which is moveable on its axes, and is intended to rest against the sides of the
excavation. The upper cross piece is tapped, and has a female screw made
therein, in which works a male screw which is actuated by a pinion, whose
bearing is secured to the cross piece of the rectangular frame. This pinion is
actuated by means of a winch, and gears into a bevil wheel on the male screw
so that the latter may be made to rotate in the female screw. A double
projecting prong is attached by a swivel joint to the upper end of the forked
frame, and by causing the male screw above mentioned to rotate in its socket,
the double prongs at each end of the apparatus are made to recede from each
other, and may therefore be forced into the sides of the excavation, so as to
hold up the framing that supports the perforating tool; this tool is secured in
a suitable holder attached to a box or carriage which is capable of being
moved to and fro in the rectangular frame, so that it may be adjusted to any
required position on the frame. Rotary motion is imparted to the boring tool
by means of a winch handle, and the tool is made to advance into the hole as
the boring operation proceeds by means of screw gearing.
A simpler form of apparatus may be made by making two frames moveable
one within the other by hand instead of by gearing. One end of each frame
is provided with a centre point for the apparatus to rest on. The upper
point may be elevated by a screw working in a box by means of a hand lever
instead of by toothed gearing as in the former instance; and the moveable
frame with the box that carries the boring tool is supported in any required
position by means of clicks made to take into the ratchet teeth of a rack on
the sides or face of the moveable frame. The box which carries the boring
tool is supported at any point on the rectangular frame by pins that rest in
notches cut on the face of the frame. The boring tool is actuated by a winch
handle as in the former instance.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Newton in the Great Seal Patent Office
on the 30th June 1862.
:
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the County 3.
of Middlesex, Civil Engineer, send greeting.

page_text: WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirty-first day of December, in the year of our
Lord One thousand eight hundred and sixty-two, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said William Edward Newton, Her special license that I, the said
William Edward Newton, my executors, administrators, and assigns, or such
others as I, the said William Edward Newton, 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 "IMPROVED APPARATUS FOR BORING ROCKS AND OTHER MINERAL
SUBSTANCES," being a communication from abroad, upon the condition (amongst
others) that I, the said William Edward Newton, by an instrument in writing
under my hand and seal, should particularly describe and ascertain the
nature of the said Invention, and in what manner the same was to be per-
formed, 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 William Edward Newton, 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 Drawing hereunto annexed,
and to the letters and figures marked thereon (that is to say) :-
This Invention relates to the construction of boring tools intended to be
employed for perforating rocks or other hard substances for the purpose of
working mines, quarries, and other analogous operations. The boring tools
constructed according to this Invention are characterized by the simplicity
of their operation and the effective work which they can perform whatever
may be the position in which they are set to work. They are of two kinds,
one of which is provided with gearing, and the other is not so provided. I
will now proceed to describe both these arrangements, reference being had to
the accompanying Drawings, in which Fig. 1 is an elevation of the boring
tool complete, and Fig. 2 is a side view of the same.
The apparatus consists of a rectangular frame B, shewn detached in front
and side elevation at Figs. 4 and 5; the internal faces of this frame on the
broadside are provided with two longitudinal dovetailed grooves (see the cross
section Fig. 6), into which take the arms of the fork A (Fig. 2); these latter
are provided at their interior with nicks or teeth c. The two sides of the

page_text: frame B are slotted, and present the appearance of a double rack, the arms of
which are connected by means of two cross pieces, the lower one of which
is provided with a claw y', which is moveable on the axle b, Figs. 1 and 2.
The upper cross piece is furnished with a central opening (Figs. 4
and 5), which serves as a bearing for a bevil wheel E, the socket or
axle of which is threaded. It also supports the shaft of the pinion p,
which receives its movement from a winch handle which may be adapted
to the square end m. The screw v which passes through the socket or axle
of the bevil wheel E and the opening o (see Figs. 2 and 14), carries a
guide C and a bolt, which is made to take into the nicks e by the action of
the helical spring r. The operation and office of this part of the apparatus
are as follows:-By sliding the fork in the grooves of the frame the claws g
and gare brought against the sides of any cutting or excavation. In order to
obtain the pressure necessary for fixing the apparatus, a winch handle is
placed upon the square end of the rod m, and by means of the pinion p rotary
motion is imparted to the bevil wheel E, which causes the screw v to turn.
This screw pushes outward the fork g to which it is connected, and presses it
against the sides of the excavation. The threads of the screw 7 are so formed
that no reaction need be feared after the tightening up has been effected.
When on the contrary the apparatus is required to be removed it is only
necessary to compress the spring with the thumb and finger, and the bolts
will then be disengaged from the teeth or nicks in the fork, and by pressing
upon the hinged claw the frame can be made to collapse.
The tool carrier consists of an iron box b, which contains the following
parts, vizt.-A shaft a', upon which is mounted the toothed wheel e' and
also a shaft a², upon which is mounted another toothed wheel e and the bevil
pinion e. The same box also contains the shaft a with the toothed wheel e
corresponding with a toothed pinion e. The toothed wheel e is furnished
with two small grooves for the reception of the arms of a collar, Fig. 13, the
office of which will be hereafter explained.
Fig. 3 represents in plan a female screw, the two parts of which are made
to approach or recede from each other by means of the screw v', which has
right and left handed threads Sand S¹. The screw S works the upper half of
the nut, and the screw S¹ the lower half, by means of the cross piece T and
two small rods n, the whole being enclosed in the frame C'. Two pins fixed
to the sides of the box serve to hold it to the racks of the frame B at any
desired height and at any desired angle. A screw v', in which two longitudinal
grooves are made, is provided with a squared end for the reception of a winch
kandle or key (see Fig. 9), the other extremity receiving the tool carrier

page_text: proper d (Fig. 1) which is fixed therein by a bayonet joint.. To this end the
tool carrier is provided with two longitudinal grooves corresponding to two
projections on the shoulder P of the screw, and with six or seven circular.
grooves, into which may be made to take the projections of a moveable ring R
(Figs. 9 and 12), which bears directly upon the shoulder P. The projections
of this shoulder have for their object to connect the tool carrier with the screw.
while rotating, the projections on the ring serving to effect the longitudinal
motion on the screw. The winch handle may be placed either direct upon
the squared end d (Fig. 1), according to the hardness of the rock to be
operated upon, when the screw will be caused to advance one thread for every
turn of the winch handle; or it may be placed upon the shaft a³, by which it
will make half a turn for every turn of the winch. By placing the winch
the squared end of the shaft a the rate of advance will be one quarter of
a thread for every turn; or a ratchet key might be made to act upon the
square d, and effect as slow an advance, as might be requisite. When the boring.
tool has entered the rock to its full extent it may be removed from the machine,
and a longer tool substituted for it; this is effected in the following manner :—
The ring R, Fig. 9, is turned slightly so as to bring its projections into the
longitudinal grooves of the tool carrier d, which will then recede freely into
the cavity of the screw in which it is placed, and the tension which exists
between the apparatus and the ground will be immediately relaxed. The
nut P is then readily unscrewed without disarranging the driving screw, which
is rapidly withdrawn and another boring tool inserted in the holder d in the
same manner as the first.
upon
Figs. 15, 16, and 17, represent different views of a boring tool without
gearing. In this arrangement A is the hollow frame forming a rack, and B,
the steel point or diamond for fixing the boring instrument; C is a second
part of the frame, and runs in the frame A. The screw E at one end moves
the point g and causes it to hold the apparatus firmly against the side corre-
sponding thereto. The apparatus may be adjusted at any desired height by
means of the double ratchet or click F which is keyed upon the shaft H. Gis
a spring for ungearing the ratchets and thus allowing the part C of the
frame to descend; this part C is fastened by means of the springs. The
tool carrier I is placed in the frame A, A, by means of an iron bearing J,
which may be opened at pleasure to facilitate the change of the boring tools,
the bearing being adjusted upon the screw by means of the set screw K. The
screw of the boring tool is actuated by a ratchet wheel L mounted in bearings
in the forked or slotted end of the lever arm L', which may be lengthened
according to the degree of hardness of the rock or earth to be operated upon.

page_text: The axle of the ratchet wheel L'is connected with the working screw of the
boring tool by means of the clutch M. In order to operate with this boring
tool the frame A must be placed in an upright position, and the screw E
turned until the claws B and g hold firmly on to the sides or other suitable
part of the excavation, so as to form a bearing or fulcrum for the apparatus to
work against; this being done it only remains to communicate rotary motion
to the boring tool; the operation is commenced by boring to the depth of
about ten inches with a tool about a foot in length; this tool is then withdrawn
and replaced by another of twice the length, and so on. This changing of the
tools will require at the most about half a minute of time.
Having now described the nature of this Invention, and having explained
the manner of carrying the same into effect, as communicated to me by my
foreign correspondent, I desire it to be understood that under the above in
part recited Letters Patent I claim the mode herein set forth of constructing,
arranging, and operating apparatus for drilling or boring rocks, minerals, and
other hard substances, as above shewn.
In witness whereof, I, the said William Edward Newton, have hereunto
set my hand and seal, this Thirtieth day of June, in the year of our
Lord One thousand eight hundred and sixty-two.
Witness,
