page_text: LETTERS PATENT to Thomas Wright Gardener Treeby, of No. 1, West-
bourne Terrace Villas, Westbourne Square, in the Parish of Paddington,
London, for the Invention of "IMPROVEMENTS IN MACHINES FOR BORING
Sealed the 27th May 1862, and dated the 3rd December 1861.
PROVISIONAL SPECIFICATION left by the said Thomas Wright Gardener
Treeby at the Office of the Commissioners of Patents, with his Petition,
on the 3rd December 1861.
I, THOMAS WRIGHT GARDENER TREEBY, of No. 1, Westbourne Terrace
Villas, Westbourne Square, in the Parish of Paddington, London, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN MACHINES
FOR BOREING HOLES IN ROCKS AND OTHER HARD SUBSTANCES," to be as
follows:-
My Invention for boreing holes in rocks and other hard substances consists
of a drill or boreing tool, which is fastened to a striking rod, which rod moves
in iron or wood framing. On this striking rod there is fastened a serrated
disc or face rachet. On this striking rod is attached a spring that gives the
blow to the boreing tool. The boreing tool is withdrawn by, a can or lug
working on a spindle; the cam or lug on the spindle rotating strikes against
the serrated disc or face ratchet; on the striking rod pressing the spring back,
as soon as the cam or lug passes the centre the striking rod is instantly

page_text: released, and the blow is given by means of the spring before named. The
cam or lug on pressing the serrated disc back slightly turns it, so that the tool
does not strike the rock in the same place. The spindle or spindles that have
the cam or lug on them are set in motion by gear work driven by any of the
known powers, such as steam, water, air, or any other engine or machine.
Any number of the striking rods can be worked at one time from one engine
or machine. Any of the striking rods can be held back by a catch at the
pleasure of the workman. When a jumping blow is not required the whole
of the striking rods are held back, and a rotary motion given to the striking
rods that hold the boreing tool. On each striking rod there is a cog wheel,
which is loose when a striking motion is required; but when a rotary motion
is required the wheel is made fast to the rod that I call the striking rod. The
cog wheels are so geared that any number of drills may rotate in boreing
through slate or soft rock; or part of the drills may rotate, and others have
the jumping motion. The iron framing, before named, is fixed on a carriage,
which carriage is so constructed that the drills may be moved in any direction
with facility.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by tlie said Thomas Wright Gardener Treeby in the Great Seal Patent
Office on the 3rd June 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
WRIGHT GARDENER TREEBY, of No. 1, Westbourne Terrace Villas, Westbourne
Square, in the Parish of Paddington, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria; by Her Letters
Patent, bearing date the Third day of December, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
'the said Thomas Wright Gardener Treeby, Her special licence that I, 'the
said Thomas Wright Gardener Treeby, my executors, administrators, and
assigns, or such otliers as I, the said Thomas Wright Gardener Treeby,
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 "IMPROVEMENTS IN MACHINES
FOR BORING HOLES IN ROCKS AND OTHER HARD SUBSTANCES," upon the condition

page_text: (amongst others) that I, the said Thomas Wright Gardener Treeby, 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 Thomas Wright Gardener Treeby,
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:
of
My Invention for boring holes in rocks and other hard substances consists
.
a drill or boring tool, which is fastened to a striking rod, which rod moves
in iron or wood framing. On this striking rod there is fastened a serrated
dise or face ratchet. On this striking rod is attached a spring that gives the
blow to the boring tool. The boring tool is withdrawn by a cam or lug
working on a spindle. The cam or lug on the spindle rotating strikes against
the serrated disc or face ratchet. On the striking rod pressing the spring:
back, as soon as the cam or lug passes the centre the striking rod. is instantly.
released, and the blow is given by means of the spring before named. The
cam or lug on pressing the serrated disc back slightly turns it, so that the tool
does not strike the rock in the same place. The spindle or spindles that have
the cam or lug on them are set in motion by gear work driven by any of the
known powers, such as steam, water, air, or any other engine or machine.
Any number of the striking rods can be worked at one time from one engine or
machine. Any of the striking rods can be held back by a catch at the pleasure
of the workman. When a jumping, blow is not required the whole of the
striking rods are held back, and
rotary motion given to the striking rods
that hold the boring tool. On each striking rod there is a cog wheel, which
is loose when a striking motion is required; but when a rotary motion is
required the wheel is made fast to the rod that I call the striking rod. The
cog wheels are so geared that any number of drills may rotate in boring
through slate or soft rock; or part of the drills may rotate, and others have
the jumping motion. The iron framing, before named, is fixed on a carriage,
which carriage is so constructed that the drills may be moved in any direction
with, facility,
)
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the inanner of performing the same.

page_text: Figure 1 shows a side elevation of the machine; Figure 2 shows a longi-
tudinal section thereof; and Figure 3 shows a front elevation thereof, the
spindles which actuate the drills or tools being shown in section.
The combined machine is mounted on flanged wheels suitable to run on and
be guided by rails laid down opposite the face of the work. a, a, are the
flanged wheels; b, the carriage, on which the machinery is mounted; c, c, is the
framing of the machine, the nature of which is clearly shown in the various
Figures of the Drawing. The framing of the machinery is mounted on a lever
frame d, d, the axes d' of which have their bearings at ₁ on the carriage as
shown, and the correct working position of the tools is obtained by means of
the adjusting screws e, e. On the upper surfaces of the two side rails d, d, of
the lever frame d, there are toothed racks d, and the lower parts of the
framing of the machinery are arranged to slide on the side rails d of the lever
framed, hence the cutting machinery may be advanced to the face of the
work step by step without the carriage being moved after it has been once
brought into position.
The machine as shewn, is arranged to actuate ten spindles, each of which is
to carry a proper tool when all are to be worked simultaneously, and the tool
carried in each case will depend on whether the spindles are for the time
working by rotation, or by being drawn back and propelled by springs. ff, are
the spindles, and as they are all similarly arranged and actuated, the descrip-
tion of the action of one will be sufficient to make all fully understood:
When desired, any number of the spindles may carry tools and be worked
separately. Machines may be similarly arranged to work with other
numbers of tools than ten. On each of the spindles f is a cog wheel g, which
is not fast to the spindle when the tool carried thereby is to be actuated by'a
spring after being moved back a distance from the work. On each of the
spindles is fixed a disc h, on the face of which are ratchet or inclined teeth.
The cog wheels on the spindles are all geared together by intermediate wheels i,
so that by giving motion to one the whole are simultaneously actuated.
are spindles on which there are cams or lugs, one to act on each of the
-discs h-in-such-manner-that-it-will-push-back-such.disch, and with it the spindle
to which it is fixed, against the pressure of the spring k on the same spindle,
and by reason of there being inclined teeth on the face of the disc h, that disc,
in addition to its being forced back by its cam or lug, will also be turned
partly round so as to change the position of the tool carried by that spindle 'j.

page_text: The spindles receive simultaneous motion by the cog wheels fixed thereon
and by the intermediate wheels, hence, by giving motion to one of the
spindles j, motion is communicated to all; but the cams or lugs ¹, on the
several spindles are arranged to act at different times and in any order desired,
according to the positions in which the lugs or cams are fixed on their
spindles. is a drum or pulley on one of the spindles j, and motion is given
by a strap, actuated by any suitable power. On one of the spindles j is
fixed an arm or crank m, the crank pin of which by a connecting rod m³, gives
motion to the driver arm n, which moves on the axis n². On the axis n¹ is
fixed a toothed wheel o, and there is also a ratchet wheel o' fixed on the same
axis. On the driver arm n is a driver n², which actuates the ratchet wheel o¹,
a distance according to the adjustment of the connecting rod. The toothed
wheel o, by an intermediate wheel gives motion to the cog wheels which gear
into the toothed racks on the lever frame, and it is by these means that the
machinery is moved up to the work a distance each time the spindles j make
a revolution. When it is desired to employ drilling tools in the ends of the
spindles f, f, their cog wheels g are to be fixed thereon, and the cams or lugs
which were used for giving the to-and-fro motion to the spindles are to be
put out of gear.
Having thus described the nature of my said Invention, and the manner.
of performing the same, I would have it understood that I make no claim to
any of the mechanical parts separately, but what I claim is the combined
arrangement herein described.
In witness whereof, I, the said Thomas Wright Gardener Treeby, have
hereunto set my hand and seal, this Third day of June, in the year of
our Lord One thousand eight hundred and sixty-two.
