Year: 1860

page_text: LETTERS PATENT to John Hobson Fuller, of 70, Hatton Garden, in the
County of Middlesex, Tool Manufacturer, and William Davidson, of
Wisbeach in the County of Cambridge, Gasfitter, for the Invention of
DAD MATAY "
PROVISIONAL SPECIFICATION left by the said John Hobson Fuller and
William Davidson, at the Office of the Commissioners of Patents with
their Petition, on the 5th April 1860.
We, JOHN HOBSON FULLER, of 70, Hatton Garden, in the County of
Middlesex, Tool Manufacturer, and WILLIAM DAVIDSON, of Wisbeach, in the
County of Cambridge, Gasfitter, do hereby declare the nature of the said
Invention for "AN APPARATUS FOR CUTTING OR SCREWING PIPES AND ROUND
METAL," to be as follows:-
This apparatus consists of a box or frame with one or more handles. One
end of the open space in such box or frame being V shaped, or sufficiently
approximating to that form to clip the pipe or round metal in two points of
its circumference, whilst from the other end of this box or frame a die is
advanced to meet the said tube or round metal, which is thus held secure
from any other motion than that round its own axis. A cutting tool attached
to this box or frame is then advanced from any suitable point of said box or
frame, and circular motion being given to the instrument, the cutter or screw.
tool is caused to cut round the pipe or round metal, and thus either cut off a

page_text: portion of the pipe or round metal, or cut or form a screw thereon as may be
arranged.
The above is a description of the nature of this Invention, the details
whereof might probably be varied in practice.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Hobson Fuller and William Davidson in the Great Seal
Patent Office on the 5th October 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
HOBSON FULLER, of 70, Hatton Garden, in the County of Middlesex, Tool
Manufacturer, and WILLIAM DAVIDSON, of Wisbeach, in the County of
Cambridge, Gasfitter, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing, date the Fifth day of April, in the year of our Lord One
thousand eight hundred and sixty, in the twenty-third year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
John Hobson Fuller and William Davidson, Her special licence that
we, the said John Hobson Fuller and William Davidson, our executors,
administrators, and assigns, or such others as we, the said John Hobson
Tuller and William Davidson, 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 APPARATUS FOR CUTTING OR SCREWING PIPES AND ROUND METAL,"
upon the
condition (amongst others) that we, the said John Hobson Fuller and William
Davidson, our executors or administrators, by an instrument in writing under our
or their, or one of their hands and seals, should particularly describe and ascer-
tain 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 we, the said John Hobson Fuller and William
Davidson, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, that is to say :-
The nature of the said Invention has already been described by the

page_text: Provisional Specification left and recorded on application for the said
Letters Patent, but in compliance with the said condition in the aforesaid
Letters Patent contained, the nature of the said Invention, and in what
manner the same is to be performed, are now particularly described and
ascertained, with reference to the accompanying Drawings, by the words,
figures, and letters marked thereon, and hereinafter referred to.
DESCRIPTION OF THE DRAWINGS.
+
Fig. 1, view of the apparatus complete. The body or stock is in two parts
marked in several parts A and B, which are secured together by screws
S, s, 8, 8. Bx is a die working in a groove or slot, in the bottom part of
the stock, and secured in its place by the top part, in which is a narrower slot ;
C and D are nuts screwing on to the stock; E is the cutter. The die (Bx)
and cutter (E,) are severally advanced or withdrawn by the nuts C and D ;
F and G are two pieces of steel let into the side of the stock. The circle
represented by the dotted lines in the centre shews a piece of tube or round metal
required to be cut, this being fixed in a vice or otherwise secured, the instru-
ment is placed over it, and the die Bx advanced, until the tube or round metal
is grasped in three places a, a, a. In this position, the instrument may be
turned round by the hand, and the cutter being gradually advanced, at each
turn it will cut through the tube or round metal, until it has divided it. The
projection 6 in the die Bx, is intended to be sometimes adopted to prevent
the instrument from slipping down the tube or round metal while being
turned. It will be seen that any sized piece of tube or round metal, which
is not too large to go through the aperture in the stock, will, when the die is
advanced to meet it, be grasped at three points a, a, a, and thus secured from
shifting and the cutter thus allowed to do its work, only cutting just so deep
at each advance as may correspond with that advance. Fig. 2, shews a
longitudinal section of the instrument. Fig. 3, represents the die Bx, and
Fig. 4, the cutter D. For screwing it will only be necessary to make the
projection 6 in the die Bx, correspond with the thread required, and the cutter
to cut only the required depth.
It is to be understood, that we do not confine ourselves to the precise
arrangements shewn, such as the method of propelling the die and cutter, and
we could also cause the cutter to be advanced from the same side as the die,
by making the die longer, and putting the second nut in front of the nut C
on the same screw to advance the cutter. Considerable variations may be
made in these matters without interfering with the peculiar nature of our
Invention.

page_text: Having now particularly described and ascertained the nature of the said
Invention, and in what manner the same is to be performed, we hereby declare
that we claim the arrangement by which a piece of tube or round metal is
grasped in three or more places, in such a manner, that while the instrument
will turn freely round the tube or round metal, the said tube or round metal
cannot shift from its position, while a cutter is advanced gradually to sever,
divide or screw the same.
In witness whereof, I, the said John Hobson Fuller have hereunto set
my hand and seal, this Fifth day of October, in the year of our
Lord One thousand eight hundred and sixty.
Signed & Sealed in my presence,
F. W. CAMPIN, Patent Agent,
Strand.
