PROVISIONAL SPECIFICATION left by the said William Husband
and Frederick Bernard Doering at the Office of the Commissioners
of Patents, with their Petition, on the Sth May 1868.
We, WILLIAM HUSBAND, of Hayle, in the County of Cornwall, Civil
.Engineer, and FREDERICK BERNARD DŒERING; of Victoria Street, in
the City of Westminster, Civil Engineer, do hereby declare the nature
of the said Invention for "AN IMPROVED MODE OF AND APPARATUS FOR

[Price 8d.]

page_text: MACHINES, PART OF WHICH APPARATUS IS APPLICABLE TO CONNECTING SUCH
MACHINES WITH THEIR STANDS OR FRAMES," to be as follows:-
Our Invention consists in securing or holding the stands or frames
of rock boring or excavating machines by means of atmospheric pressure.
For this purpose we employ a disc or sheet of india-rubber, leather,
or other suitable air-tight material; we secure this disc or sheet between
two horizontal plates, the under plate being of smaller dimensions than
the disc or sheet. The upper plate has near its circumference four
or other convenient number of screw-threaded holes to receive a cor-
responding number of screws, and the centre of this plate is forged
or secured to an upright arm or bar which is connected by a ball-and-
socket joint or other like form of connection to another arm, and this
arm which may be telescopic is in its turn connected by a double or
a universal joint to the stand or frame of the machine. On the floor
of the tunnel or gallery in which the machine is working we lay
some clay or like material, then apply the rubber disc thereon and
press down the edges of the disc; we next produce a vacuum beneath
the disc by a small pump or by the condensation of steam or by other
means, and we then screw down the screws into the floor outside the
disc. The pressure of the atmosphere will thus hold or secure
the
disc and consequently the stand or frame of the machine.

surface the clay or like material might be dispensed with. In some
cases the vacuum may be produced by lifting the apparatus after
pressing down the edges of the disc. Sometimes the screws may be
dispensed with. Sometimes also we employ lateral supports for the
upright arm to prevent vibration of the disc.

The mechanical arrangement herein-before described consisting of two
arms connected together by a ball and socket joint or other like form
of connection, one of such. arms being connected by a double or
universal joint to the stand or frame of the engine, may be applied
in shaft sinking. For this purpose the lower end of the bars on which
the engine works rests on the bottom of the shaft, while the arm which
is not connected to the engine is secured to one or more beams or
bars fixed horizontally in the shaft.

minster, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of May, in the year of our
Lord One thousand eight hundred and sixty-eight, in the thirty-first
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said William Husband and Frederick Bernard
Deering, Her special licence that we, the said William Husband and.
Frederick Bernard Deering, our executors, administrators, and assigns,
or such others as we, the said William Husband and Frederick
Bernard Deering, our 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 "AN IMPROVED MODE OF AND APPARATUS FOR
SECURING OR HOLDING THE STANDS OR FRAMES OF ROCK BORING OR EXCAVATING
MACHINES, PART OF WHICH APRARATUS IS APPLICABLE TO CONNECTING SUCH
MACHINES WITH THEIR STANDS OR FRAMES," upon the condition (amongst.
others) that we, the said William Husband and Frederick Bernard
Doering, or one of us, our executors or administrators, by an instrument
in writing under our, or one of our 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 sanie 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 we, the said William Husband and Frederick
Bernard Deering, do hereby declare the nature of our 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,

page_text: reference being had to the Drawings hereunto annexed, that is
to say:-
Our Invention consists in securing or holding the stands or frames
of rock boring or excavating machines by means of atmospheric
pressure. For this purpose we employ a disc or sheet of india-rubber,
leather, or other suitable air-tight material; we secure this disc or
sheet between two plates, the under plate being of smaller dimensions
than the disc or sheet. The upper plate has near its circumference
four or other convenient number of screw-threaded holes to receive
a corresponding number of screws, and the centre of this plate is forged
or secured to an upright arm or bar which is connected by a ball-and-
socket joint or other like form of connection to another arm, and this
arm which may be telescopic is in its turn connected by a double or
a universal joint to the bars or frame of the machine. On the ground
where the machine is working we lay some clay or like material, then
apply the rubber disc thercon and press down the edges of the disc.
We next produce a vacuum beneath the disc by a small pump or by the
condensation of steam or by other means, and we then screw down
the screws into the ground outside the disc. The pressure of the
atmosphere will thus hold or secure the disc, and consequently the stand
or frame of the machine. One or more of our apparatus may be
employed as found necessary. On a smooth surface the clay or like
material might be dispensed with. In some cases the vacuum may be
produced by lifting the apparatus after pressing down the edges of the
disc. Sometimes the screws may be dispensed with; sometimes also
we employ lateral supports for the upright arm to prevent vibration of
the disc.
Figure 1 of the accompanying Drawings represents an apparatus
constructed according to our Invention for securing or holding the
stand or frame of a rock boring machine.
a is a disc of leather, rubber, or other air-tight material secured
between two plates b, c, the under plate 6 being of smaller dimensions
than the disc a. The upper plate c is formed with screw-threaded
holes to receive corresponding screws d, d, and the centre of this
plate is forged with an upright bar e, which is connected by a ball-
and-socket joint to an arm g; this aring is in its turn connected
by a branch and a double joint i, j, to the upper connecting piece
of the bars on which the engine works. The upper end of the

screw n, and the joint i is also made fast. o is a pump, by means
of which a vacuum is produced below the disc a; p is a lateral support
carried from the upright e to the lower connecting piece of the bars ;
this support is adjustable according to the angle of the bars

inner ring or frame 2, which in its turn is provided with
to receive trunnions on a cross piece n of bars o, o.
connected by end pieces to other bars o', o', on which the engine
works. The bearings k, k, and m, m, form a double joint, by means of
which the bars 0, 0, 0', o', can be moved into any required position.
When the proper position is obtained the bars are fixed by screwing
up the screws p, p, the trunnions being conical. 9, 9, arc screws passed
through threaded holes in the feet of the legs h; by turning these
screws so as to raise the legs a vacuum is formed below the discs a,
and the atmospheric pressure above these discs serves to hold the whole
apparatus securely.
The mechanical arrangement first herein-before described and repre-
sented in Figure 1 consisting of two arms connected together by a
ball-and-socket joint or other like form of connection, one of such
arms being connected by a double or universal joint to the bars or
frame of the engine may be applied in shaft sinking. For this purpose
the lower end of the bars on which the engine works rests on the bottom
of the shaft while the arm which is not connected to the engine is

This arrangement is represented in elevation in Figure 4.
a, a, represent the bars on which the engine works; they rest at
their lower ends on the bottom of the shaft as shown. b, c, are the
two arms connected together by a ball-and-socket joint d; the arm b
is also connected by a double joint e, f, to the cross piece of the hars a.
The arm is rigidly connected to beams g fixed horizontally in the
shaft and forming the stand of the machine.
Figure 5 is a plan view on a smaller scale, showing the beams g and
the mode in which they are fixed in the shaft.
And having now described the nature of our said Invention, and
in what manner the same is to be performed, we declare that we
claim,―
First. Securing or holding the stands or frames of rock boring or
excavating machines by means of atmospheric pressure, substantially
in the manner herein-before described.
Secondly. Constructing apparatus substantially as herein-before
described and represented in Figures 1, 2, and 3, of the accompanying
Drawings for securing or holding the stands or frames of rock boring
or excavating machines.
Thirdly. Connecting rock boring or excavating machines with their
stands or frames by apparatus arranged and combined as herein-before
described and represented in Figure 4 of the accompanying Drawings.
In witness whereof, I, the said Frederick Bernard Doering, for
myself and on behalf of the said William Husband, have here-
unto set my hand and seal, this Fifth day of November, One
thousand eight hundred and sixty-eight.
