Year: 1859

page_text: LETTERS PATENT to Daniel Joseph Fleetwood, of Birmingham, Copper
Agent, for the Invention of "IMPROVEMENTS IN MACHINERY FOR RAISING
AND STAMPING METAL."
Sealed the 11th April 1860, and dated the 15th December 1859.
PROVISIONAL SPECIFICATION left by the said Daniel Joseph Fleetwood
at the Office of the Commissioners of Patents, with his Petition, on the
15th December 1859.
I, DANIEL JOSEPH FLEETWOOD, of Birmingham, Copper Agent, do hereby
declare the nature of the Invention for "IMPROVEMENTS IN MACHINERY FOR
RAISING AND STAMPING METAL," to be as follows:-
This Invention has for its object improvements in machinery for raising and
stamping metal. For these purposes the bed or bottom die is made with a
forcer or ram which passes through the other part of such bed or bottom die,
and the upper end of such forcer or ram is formed with part of the device of
the bottom or bed die. The upper die is also formed with a ram or forcer
which passes through it. The ram or forcer of the bottom or bed die is
capable of being actuated by hydraulic or other suitable power. The ram or

page_text: forcer of the upper die is also capable of being actuated by hydraulic or other
suitable power, and its under surface is made with part of the device of the
upper die thereon or therein. The other part of the upper die is made
capable of sliding freely up and down on the upper ram or forcer, and such
other part of the upper die is actuated by any suitable mechanism, so as
to give a quick up-and-down motion to it whilst its ram or forcer is stationary
or being slowly pressed down into the lower or bed die, which, as above stated,
consists partly of a fixed die and partly of a ram or forcer; by these means, as
the sheet metal blank is pressed slowly into the lower or bed die, puckers are
prevented forming or are beaten out as they form in the edges or sides of the
metal, which protrude beyond the central portions which are being acted on by
the descending forcer. I would state that, although I have spoken of the
combination as acting with a fixed bed or bottom die, this may be reversed, and
the upper die with its forcer may be retained stationary whilst the lower forcer
or ram is pressing the metal on to or into the upper die, the other part of the
bottom or bed die in such case having motion-given to it in such manner as to
prevent the forming or to beat out any puckers as they form. In some cases
also the upper ram or forcer may be retained stationary whilst the other part
of the upper die is moved quickly up and down to prevent or beat out puckers
in the metal, in which case the lower ram or forcer would be gradually raised
to press up the metal into the upper die.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Daniel Joseph Fleetwood in the Great Seal Patent Office
on the 14th June 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DANIEL
JOSEPH FLEETWOOD, of Birmingham, Copper Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by IIer Letters
Patent, bearing date the Fifteenth day of December, in the year of our
Lord One thousand eight hundred and fifty-nine, in the twenty-third year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Daniel Joseph Fleetwood, Her special licence that I, the said
Daniel Joseph Fleetwood, my executors, administrators, and assigns, or such
others as I, the said Daniel Joseph Fleetwood, 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

page_text: lawfully might make, use, exercise, and vend, within the United Kingdom of
Great Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN MACHINERY FOR RAISING AND STAMPING METAL,"
upon the condition (amongst others) that I, the said Daniel Joseph Fleetwood,
my executors or administrators, by an instrument in writing under my, 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 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 Daniel Joseph Fleetwood, 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 thereof, that is to say:-
This Invention has for its object improvements in machinery for raising
and stamping metal. For these purposes the bed or bottom die is made with
a forcer or ram which passes through the other part of such bed or bottom
die, and the upper end of such forcer or ram is formed with part of the device
of the bottom or bed die. The upper die is also formed with a ram or forcer
which passes through it. The ram or forcer of the bottom or bed die is
capable of being actuated by hydraulic or other suitable power. The ram or
forcer of the upper die is also capable of being actuated by hydraulic or other
suitable power, and its under surface is made with part of the device of the
upper die thereon or therein. The other part of the upper die is made
capable of sliding freely up and down on the upper ram or forcer, and such
other part of the upper die is actuated by any suitable mechanism, so as
to give a quick up-and-down motion to it whilst its ram or forcer is stationary
or being slowly pressed down into the lower or bed die, which, as above stated,
consists partly of a fixed die and partly of a ram or forcer. By these means, as
the sheet metal blank is pressed slowly into the lower or bed die, puckers are
prevented forming or are beaten out as they form in the edges or sides of the
metal, which protrude beyond the central portions which are being acted on
by the descending forcer. I would state that, although I have spoken of the
combination as acting with a fixed bed or bottom die, this may be reversed,
and the upper die with its forcer may be retained stationary whilst the lower
forcer or ram is pressing the metal on to or into the upper die, the other part
of the bottom or bed die in such case having motion given to it in such
manner as to prevent the forming or to beat out any puckers as they form.

page_text: Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING,
Which represents a vertical section of machinery combined according to my
Invention. The Drawing shews the forcers or rams of the upper and lower
dies to be actuated by hydraulic power, which is what I prefer to be the case,
but other power may be employed to actuate the forcers. a, a, is the framing;
b, c, is the lower or bed die, the form of which will as heretofore depend on the
nature of the article to be produced thereon. This lower die is made in two
parts, the part is the central part or forcer, and c is the outer part of the
lower dic, which in the arrangement shewn is fixed. The upper die is also
made in two parts; the part d is the central part or forcer, and the part e is
the outer part of the die, which in the arrangement shewn is made moveable,
and receives a quick up-and-down motion by any suitable mechanism, the
object being that the outer circumference of the sheet metal should be sub-
jected to quick blows as the central portion of the sheet metal is progressively
pressed into the lower die by the central portion d of the upper die. The
Drawing shews a simple example of upper and lower dies, but the forms of
dies used may be greatly varied, and such is the case in regard to the relative
proportions which the central parts b, d, shall have to the external parts c, c.
Water is supplied to act on the hydraulic rams ƒ and g by the pipes h and i
from suitable pumps. The upper die e is arranged to receive a quick up-and-
down motion by means of connecting rods j, which at their upper ends are
connected to the die e, and at their lower ends are connected to the beam k,
which is actuated by any suitable mechanism. I would remark that sheet
metal has before been raised, in some cases by means of impact and suitable
dies, and in other cases by means of continuous pressure by hydraulic or other
power in suitable dies. And in some cases each of these methods of raising
sheet metal has been used in combination with pressing plates to press at the
circumference on the sheets of metal as they are being raised in dies, the outer
edges or circumference of the sheet metal in each case being drawn between
such pressing plate and the upper surfaces of the lower die. I mention these
matters in order to state that I make no claim thereto, neither do I claim any

page_text: of the mechanical parts separately. I would state in conclusion that
the peculiarity of my Invention consists in combining machinery as herein
described.
In witness whereof, I, the said Daniel Joseph Fleetwood, have hereunto
set my hand and seal, this Eighth day of June, in the year of our
Lord One thousand eight hundred and sixty.
