Year: 1848

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, we, DANIEL
WATNEY, of Wandsworth, in the County of Surrey, Distiller, and JOHN JAMES
WENTWORTH, of Wandsworth, Engineer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Twelfth day of October,
One thousand eight hundred and forty-eight, in the twelfth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Daniel Watney and John James Wentworth,.our exors, adññors, and assigns,
His especial licence, full power, sole privilege and authority, that we, the said
Daniel Watuey and John James Wentworth, our exors, admors, and assigns,
or such others as we, the said Daniel Watney and John James Wentworth,
our exors, aditiors, or assigns, should at any time agree with, and no others,
from time to time and at all times during the term of years therein expressed,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, our Invention of "IMPROVE-
NENTS IN MACHINERY FOR DRILLING METAL AND OTHER SUBSTANCES;" in which said
Letters Patent is contained a proviso, that we, the said Daniel Watney and
John James Wentworth, or one of us, should cause a particular description of
the nature of our said Invention, and in what manner the same, is to be per-
formed, by an instrument in writing under our hands and seals, or under the
hand and seal of one of us, to be inrolled in Her Majesty's High Court of

page_text: •
Chancery within six calendar months next and immediately after the date of
the said in part recited Letters Patent, as in and by the same, reference being
thereunto bad, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, we, the said
Daniel Watney and John James Wentworth, do hereby declare that the
nature of our said Invention, and the manner in which the same is to be
performed, are fully described and ascertained in and by the following state-
ment thereof, reference being had to the Drawing hereunto annexed, and to
the figures and letters marked thereon, that is to say:-
DESCRIPTION OF THE DRAWING.
Figure 1 shews a front view, Figure 2. a back view, and Figure 3 a side
view, of apparatus combined according to our Invention; Figure 4 shews some
of the details separately; and in each of these Figures the same letters of
reference indicate similar parts. a, a, is a frame, placed on a foot b in such
manner that it may be turned on the pin c, the screw nut d retaining the
frame secure. At the upper part of the frame there is a screw e, carrying at
its upper end the disc or plate f, which can turn freely on the upper part of
the stem of the screw e. By this arrangement of the frame a (and parts con-
nected therewith) the frame a may be securely retained between two fixed
parallel surfaces, such as between the floor and roof or ceiling of a room or of
a mine. g is a block, which slides up and down in the frame a; and his a
clamping plate, by which the block is retained in any position it may be
placed. The block 9 and plate h are combined by the screw and nut i, j, the
stem of the screw i being conical, by which arrangement the screw i and parts
connected may be held securely, and the screw socket k at the end of the stem
of the screw i will be held in any desired position, and so that the screw
which passes through the socket k will be held in a horizontal position, or at
any angle to a horizontal line; and as the frame a can move on its axis and be
readily taken down and moved and again secured between two fixed parallel
surfaces, whether such two fixed parallel surfaces lie horizontal, or vertical, or
otherwise, this drill machinery may be used under very varying circumstances.
The end of the drill used enters the end of the screw and turns therein as a
bearing, and motion is to be communicated to the drill as heretofore. It will
readily be seen that the drill will thus readily be made to act in any direction,
and may thus be employed under circumstances where the matters to be
drilled are fixed, or otherwise cannot be conveniently moved to the drill; and
owing to the screw / being readily set aud held in any direction in respect to
the frame a, the action of the action of the drill may be in a horizontal or

page_text: angular direction. Thus, supposing the frame a be fixed between the roof and
floor of a mine, or of a tunnel, or other works where rock is to be blasted, and
it be desired to drill holes for such purpose, it will be evident that such holes.
may be in any desired direction, owing to the capability of universal movement
of the parts which govern the direction in which the drill shall work. We
would remark that although we prefer the frame a to be an open frame, such
as is shewn, this construction or arrangement may be varied; and although we
have described the end of the drill as being received on to the end of the
screw 7, this mode of holding the drill may be varied.
Having thus described the nature of our Invention, and the manner in
which the same is to be performed, we would have it understood that we do
not claim any of the parts separately; but what we claim is, the mode herein
described of combining parts into a machine for drilling metal and other
substances.
In witness whereof, I, the said John James Wentworth, have hereunto
set my hand and scal, this Twelfth day of April, in the year of our
Lord One thousand eight hundred and forty-nine.
