page_text: LETTERS PATENT to James Ker Gulland, of the Westminster Palace Hotel,
Victoria Street, in the City of Westminster, Mechanical Engineer, for the
Invention of "IMPROVEMENTS IN APPARATUS FOR BORING OR DRILLING IN
STONE AND OTHER MATTERS.”
PROVISIONAL SPECIFICATION left by the said James Ker Gulland at the
Office of the Commissioners of Patents on the 10th April 1877.
JAMES KER GULLAND, of the Westminster Palace Hotel, Victoria Street, in the
City of Westminster, Mechanical Engineer. "IMPROVEMENTS IN APPARATUS FOR
BORING OR DRILLING IN STONE AND OTHER MATTERS."
The object of the Invention is to facilitate the operations of boring or drilling
in stone and other matters.
One part of the Invention relates to means for correctly holding the boring or
drill bar in the socket, to which the required rotary motion is given for the action
of the cutter, so as readily to admit of the passage of cutters and their bars of
different sizes. For this purpose the socket is formed to receive loose blocks
adapted to fill up the socket to the rod, so that whilst the rod is free to slide
lengthwise in the socket it is controlled to revolve with the socket; and the blocks
may be varied to the size or form of the rod for the time to be used.
The object of another part of the Invention is to enable the guide block to the
top bar to be readily turned radially clear of the lifting or lowering tackle, so as
to admit of the admission or removal of lengthening bars. For this purpose the
guide block is capable of moving on a fin or feather, or such like guide, to near the
end of its motion or other part desired, when by clearing such guide it is free to
be moved radially with its upper rod.
Another part of the Invention relates to means for controlling the weight of the
boring or drilling rods, so as to regulate the action of the cutter. For this purpose
one end of the chain or other band supporting the boring rods is connected to a
cylinder or other piston rod thereof, which cylinder is filled with water or other
fluid provided with a passage from one side of the piston to the other thereof, and
which passage is provided with a weighted valve capable of adjustment to regulate
Povice 1

page_text: the extent of opening from one end of the cylinder to the other, according to the
pressure or force desired to be exerted for the time being. The piston rod or its
cylinder is formed with rack or other suitable gear to work with the means for
giving rotary motion to the drill rods, yet so as to be capable of being operated
independently thereof by land or power.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said James Ker Gulland in the Great Seal Patent Office on the 10th October
1877.

The object of another part of the Invention is to enable the guide block to the
top bar to be readily turned radially clear of the lifting or lowering tackle, so as
to admit of the admission or removal of longthening bars. For this purpose the
guide block is capable of moving on a fin or feather, or such like guide, to near the
end of its motion or other part desired, when by clearing such guide it is free to
be moved radially with its upper rod.
Another part of the Invention relates to means for controlling the weight of the
boring or drilling rods, so as to regulate the action of the cutter. For this purpose one
end of the chain or other band supporting the boring rods is connected to a
cylinder, or the piston rod thereof, which cylinder is filled with water or other
fluid provided with a passage from one side of the piston to the other thereof, and
which passage is provided with a weighted valve capable of adjustment to regulate
the extent of opening from one end of the cylinder to the other, according to the
pressure or force desired to be exerted for the time being. The piston rod or its
cylinder is formed with rack or other suitable gear to work with the means for
giving rotary notion to the drill rods, yet so as to be capable of being operated
independently thereof by hand or power.
But that the Invention may be better understood I will, by the aid of the
accompanying Drawings, proceed to describe means pursued by me in carrying the
saine into effect.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows by section parts of apparatus arranged according to my Inven-
tion; Figures 2 and 3 are horizontal sections of Figure 1.
In each of those Figures the same letters indicate corresponding parts.
a represents the framing the apparatus; b, a drill; and c, portions of the tube
to which the drill is immediately attached; whilst & represents portions of the drill
bar, or of a series of them; e is a socket, by which rotary motion is given to this
bar d, or the series of them for the time in use, and thence to the drill tube and the
drill. This socket c is formed with a neck, and it is supported so as to be capable
of revolving freely with that neck in the bearing f formed for it, such bearing
retaining the socket e by its neck, so that it may hold the socket e against pressure

page_text: exerted upon it in either its upward or downward directions. The bearing fis
sustained by fixture to the framing a, and in order that the socket e may be
capable of receiving through it bars d and drill tubes c of various diameters, the
hole through it for the passage of these parts is formed in size to admit of tho
passage of the largest of them likely to be employed. For smaller rods & blocks g
are employed, the exterior diameter of which is formed to correspond with the
internal diameter of the socket e, whilst the interior or bore thereof corresponds
with the diameter of the bar & for the time in use; or there may be two or more
of such blocks formed to fit one within the other, so as when so fitted to act simply
as the bore of the socket e. For this purpose the block g is formed with a recess
corresponding with that in the socket e to receive feathers g', and when there is
more than one of such blocks used one within the other. Then cach will be corre-
spondingly formed and connected, so that the block or blocks for the time in use
may operate on the bar d as part of the socket e, and the fin or feather in the
interior of the block next the rod d will be received into a corresponding groove in
the upper of the rods d, so as to cause the rotation of the rods d and parts carried
thereby in the rotation of the socket c. The socket e is formed with or has applied
to it the wheel e' with bevilled teeth, which are taken into by the teeth of the
bevilled wheel affixed on the axis or shaft h, upon which is supported, with
capability of free rotation, the two bevilled wheels ³, h³; and either of these
wheels or is by clutch connection * capable of being made fast to the shaft h¹,
so that when rotary motion is given to these bevilled wheels rotary motion will be
given to such shaft in the direction corresponding with that of the wheel h² or h
for the time clutched to it.
The wheels h³, ³, are caused to revolve by their teeth being taken into by the
teeth of the bevilled wheel h affixed on a shaft or axis, to which rotary motion is
given by suitable connecting means from a steam engine or other suitable power.
i represents the top block to the upper or top bar d of the series of bars d. This
block i is in the working for boring or lifting from boring of the boring tools
guided in its correct vertical motion by means of the feathers i, i, formed on the
cylindrical portion a¹ of the framing a, and which feathers pass into recesses
formed for them in the opposite inner surfaces of the block i; but according to
another part of my Invention these fins or feathers i¹, i, are not continued to the
full extent of the upward motion of which the block i is capable on the cylinder a¹,
so that when the block i has been raised by the lifting tackle above the fins or
feathers,, the block i may be turned radially on the frame a¹, as indicated by
dotted lines i* in Figure 2, for the purpose of facilitating the application or removal
of lengthening bars d.
I will now describe that portion of my Invention which relates to means for
controlling the weight of the boring or drilling rods, so as to regulate the action of
the cutter.
As shown, there are two chains or bands j, which are attached at 1 to the block i,
and they pass over pulleys for the support of the blocks i and the rods and
cutting apparatus carried thereby. These chains or bands ; thence pass down
within the framing a¹ under pulleys 1, and are connected to the opposite sides of
the cylinder k; and this cylinder is formed with stuffing boxes in each cover k¹, k¹,
for the free but close passage of the stationary rod l, on which is affixed, as shown,
the piston m. The cylinder is formed, as shown by the separate sectional side
view thereof, Figure 4, with a passage at each end thereof, and which passages
are connected by the pipes, to the valve chamber n, in which there are two
valves o, o. When there is excess of pressure within the cylinder in one
direction the water at one end of the cylinder will be forced through the pipe, say,
and valve o, thence through the pipe to the other end of the cylinder. Or
by endway pressure on the cylinder
cylinder will be forced through the
end of the cylinder, and any excess of
the weighted lever p on the valve o¹.
in the opposite direction the water in the
pipe, valve o¹, and pipe ³, to the opposite
pressure will be checked by the operation of
The pulleys are supported on the cap a²,

page_text: which is free to turn on the upper end of the framing a' in the radial motion of
the block . The cylinder is formed with a rack, the teeth of which are taken
into by the teeth of a pinion indicated by the dotted lines q affixed on a shaft or
axis q, on which is affixed another tooth wheel, the teeth of which take into the
teeth of a pinions on a shaft s¹, on which is applied a worm wheel, which, when
desired, is capable of clutch connection with the screw wheel t on the shaft or
axis ¹.
It will readily be understood that in place of the cylinder being at liberty to
move for the required action whilst the piston and piston rod are stationary the
cylinder may be stationary, and the required action obtained by the movement of
the piston and piston rod. The number and the direction of motion of such
cylinder and parts may be also varied.
Having thus described my Invention, and incans which I adopt for carrying the
same into effect, I would have it understood that I do not confine myself to the
precise arrangements of parts as shown and described, as the same may be varied
without departing from the peculiar character of my Invention, but what I do
claim is,―
First. The application of loose or moveable blocks to the sockets for the correct
holding of the boring rods in apparatus used in boring or drilling in stone and other
matters, substantially as described.
Secondly. I claim the arranging or combining parts so that the guide block to
the top bar used in apparatus for boring or drilling in stone, or other matters, may
be readily turned in a radial direction to facilitate change or removal of drill bars,
substantially as described.
And, Thirdly. I claim the arranging or combining parts in apparatus of the
character referred to for controlling the weight of the boring or drilling rods, sub-
stantially as described.
In witness whereof, I, the said James Ker Gulland, have hereunto set my
hand and seal, this Ninth day of October, in the year of our Lord One
thousand cight hundred and seventy-seven.

ALFRED GEORGE BROOKES.
