page_text: LETTERS PATENT to William Edward Newton, of the Office for Patents.
66, Chancery Lane, in the County of Middlesex, Civil Engineer, for the
Invention of "IMPROVED MACHINERY FOR RIMING AND TAPPING GAB
FITTINGS." A communication.
Sealed the 3rd March 1857, and dated the 4th November 1856.
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on
the 4th November 1856..
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Civil Engineer, do hereby declare the nature of
the said Invention for "IMPROVED MACHINERY FOR RIMING AND TAPPING GAS
FITTINGS," to be as follows:-
This Invention of improved machinery for. riming and tapping gas fittings
consists in the employment of a peculiarly constructed holder for carrying the
necessary tapping and riming tools, in combination with a rotary chuck or clamp
for holding the fittings, the whole being so arranged that the various riming
tools and taps may be brought to bear in succession as required upon the fittings
without removing either the tools or the taps from the lathe. The clamp in
which the gas socket to be operated upon is mounted is provided with movable
jaws, one of which is adjusted by a hand, wheel and screw on one side of the

page_text: clamp, so as to bring the centre of the fitting into the proper position, and the
other jaw is moved as required to and from the other by a handle and screw
on the other side of the clamp.
The shaft of the clamp turns in standards, and carries upon one end a wheel,
in which are made notches, and into these notches a spring bolt enters, by
which means the clamp may be secured in the required position. The clamp
may be turned on its axis, so as to bring either one of the ends of the fitting
opposite the cutters or rimers, which are secured to or fixed on a rotating holder.
The cutter holder may be turned upon its axis within the forked end of a
shaft which revolves in the standards, and is driven by power applied to the
pullies connected with the shaft, the band which actuates the pullies being so
arranged that the direction of its motion may be instantly reversed by means
of an ordinary shipper lever, or otherwise. The shaft which carries the cutter
holder slides freely in its boxes, and is brought up to its work by a band lever.
A spring bolt enters holes in the holder, by which nieans the latter is held
clamped to its forked carrier or shaft while in operation. The cutter holder is
provided with cutters or rimers for clearing out the socket, which may then
be tapped by a small screw, also fixed in the cutter holder. Any cutter,
rimer, or screw tap may be brought with facility opposite the socket by merely
turning the holder round on its axis.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Newton, in the Great Seal Patent Office
on the 4th May 1857.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of November, in the year of our Lord
One thousand eight hundred and fifty-six, in the twentieth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Edward Newton, Her special license that I, the said
William Edward Newton, my executors, administrators, and assigns, or such
others as I, the said William Edward Newton, 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 King-

page_text: dom of Great Britain and Ireland, the Channel Islands, and Isle of Man,
an Invention for "IMPROVED MACHINERY FOR RIMING AND TAPPING GAS
FITTINGS," being a communication from abroad, upon the condition (amongst
others) that I, the said William Edward Newton, by an instrument in
writing under my hand and seal, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to bo
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 William Edward Newton, 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, reference being had to the Drawings hereunto annexed,
and to the letters and figures marked thereon (that is to say) :-
This Invention of "Improved Machinery for Riming and Tapping Gas
Fittings," consists in the employment of a tool holder, provided with bits or
tools, and capable of being turned upon an axis in jaws, upon the end of the
revolving spindle which carries it, the axis of rotation of the tool holder being
at right angles to the axis of revolution of the spindle, so that any one of
the tools may be brought into line with the spindle, and made to revolve there-
with.
In combination with the above, the Inventor makes use of a rotary chuck
or clamp, for holding the fittings, the whole being so arranged that the various
riming tools and taps may be brought to bear as required upon the fittings
without removing either the tools or the fittings from the lathe, as will be
hereafter more fully explained.
In the accompanying Drawings, Fig. 1 is a plan or bird's-eye view of the
improved machinery; Fig. 2 is a side elevation; Fig. 3, a transverse vertical
section through the clamp which holds the fitting; Fig. 4 is a view of the
tap holder, and Fig. 5 is a detached view of the clamp which holds the fitting.
A is the bed of the machine, to which the operating parts are secured; Lis
the tool holder, in which are secured the riming tools f, i, and the taps g, m.
This holder, which is shewn detached in Fig. 4, is bung within the forked end
T of the shaft M, and may be turned upon a pin d, so as to bring any one of
the riming tools or taps in line with the shaft. The holder is held in the
required position by the spring bolt p, which enters one or other of the holes s.
The shaft M revolves in the standards N, and is driven by power applied to
the pullies O, which are connected with the shaft by a spline, so as to allow
it to move longitudinally through them, and at the same time to rotate there-

page_text: with, the band which operates the pulleys being so arranged that the direction
of its motion may be instantly reversed by means of an ordinary shipper lever,
or otherwise.
The bandle P is pivoted at one end to the machine, and is connected with
the shaft M, so that by means of this handle the shaft may be run in and out
as required, to bring the tools up to their work or to withdraw them there-
from.
B is the clamp or chuck, in which is secured the gas fitting or other article
to be operated upon. This clamp, which is shewn detached in Fig. 5, is pro-
vided with moveable jaws, one of which (D, Fig. 3) is adjusted by the hand
wheel F and screw E, so as to bring the centre of the fitting into the proper
position; the other jaw C being moved as required to and from the jaw D by
means of the handle y upon the screwed shaft z.
The clamp B is provided with hollow gudgeons G, which rest in bearings
in the standards H, and through the centre of which pass the clamp screws E
and. To one of the gudgeons G is secured the wheel I, into the notches
a, b, c, of which the spring bolt K enters, by which means the clamp may be
secured in the required position to bring one or other of the ends of the
fitting in line with the shaft M. The operation of the machine is as follows:-
The axes of the shafts G and M being arranged at the same height above
the bed plate A, the jaw D of the fitting clamp or holder is adjusted so as to
bring the centre of the fitting R within the axis of the shaft M, and the fitting
is clamped, as seen in the Drawings, by bringing up the jaw C. When once
adjusted, the jaw D does not require to be changed until a fitting of a different
size is to be operated upon. The fitting being clamped in the position shewn
in Figures 1, 2, and 3, the tap or tool holder L is turned so as to bring the
large rimer in line with the centre of the fitting, the rimer shaft M is then
made to revolve, and the rimer is brought up to its work by means of the hand
lever P. After the opening in the fitting is suitably enlarged, the holder L
is revolved upon its axis d, and the large tap g is brought up, by which one
of the female screws in the "rim" is formed. The tap is then withdrawn by
reversing the motion of the band which drives the pulley O, and the fitting is
revolved one hundred and eighty degrees, so as to bring its opposite end
into position to be operated upon by the same tools. The fitting is then
turned, so as to bring the "outlet" opposite to the tool holder, and the
smaller rimer i is brought up, then the corresponding tap m, and the three
screws are completed.
By the use of this machine a much larger amount of work may be
accomplished than has been found practicable by the means heretofore

page_text: employed for the purpose, while the work is done with an accuracy entirely
unattainable by the hand process.
Having now described the Invention of "Improved Machinery for Riming
and Tapping Gas Fittings," as communicated to me by my foreign corre-
spondent, I would remark, that I do not claim as new the use of a tool holder
which can turn independently of the jaws which hold it, as in the case of a
shoemaker's punch, nor do I claim a revolving tool holder, capable of holding
and operating a variety of tools one at a time, as in an ordinary bit stock;
but what I do claim as new in the above described improved machinery, and
desire to secure by Letters Patent, as aforesaid, is the combination of the tool
holder with its spindle, when the said tool holder is provided with a series
of bits or tools, and is capable of being turned upon an axis at right angles
to and independent of the axis of the spindle, so that either tool may be
revolved in a line with the axis of the spindle, for the purpose above
described.
I also claim the use of the rotating tool holder in combination with tho
revolving chuck or clamp B, for holding the fitting for the purpose herein
shewn and described.
In witness whereof, 1, the said William Edward Newton, have hereunto
set my hand and seal, the Second day of May, in the year of
our Lord One thousand eight hundred and fifty-seven.
Witness,
J. W. MOFFATT,
