page_text: LETTERS PATENT to George Flint, of Skinner Street, Bishopsgate Without,
in the City of London, Engineer, Thomas Wood, of Tachbrook Street,
Pimlico, in the County of Middlesex, and Edward Wood, of Tachbrook
Street aforesaid, for the Invention of "AN IMPROVED PUNCHING PRESS OR
MACHINE ADAPTED TO THE PURPOSES OF STAMPING, COINING, SLOTIING, AND
EMBOSSING. AND FOR CUTTING METAL AND OTHER SUBSTANCES."
Sealed the 24th March 1857, and dated the 1st October 1856.
PROVISIONAL SPECIFICATION left by the said George Flint, Thomas
Wood, and Edward Wood at the Office of the Commissioners of Patents,
with their Petition, on the 1st October 1856.
We, GEORGE FLINT, of Skinner Street, Bishopsgate Without, in the City
of London, Engineer, THOMAS WOOD, of Tachbrook Street, Pimlico, in
the County of Middlesex; and EDWARD WOOD, of Tachbrook Street aforesaid,
do hereby declare the nature of the said Invention for "AN IMPROVED
PUNCHING PRESS OR MACHINE ADAPTED TO THE PURPOSES OF STAMPING, COINING,
SLOTTING, AND EMBOSSING, AND FOR CUTTING METAL AND OTHER SUBSTANCES," to be
as follows:-
This Invention consists, firstly, in so constructing a punching press or
machine as that the power is exerted from a cam or eccentric direct upon the
punching tool or other implement employed, instead of through the medium of
a lever or levers, as heretofore commonly practised in presses or machines

page_text: employed more particularly for punching holes in metal; and, secondly, in so
arranging and constructing the mechanism of such said press as that it shall
occupy considerably less space and be very much cheaper than ordinary
punching presses or machines." These improvements are effected by the
following means-Suppose, for example, the press is required to perform the
combined operations of cutting métal at one end of the "press, and punching
holes at the opposite end thereof, we arrange the moveable cutting shear and
the punch holder one above the other in an upright recess formed in the stand
or body of the press, and capable of sliding therein; between these two pieces
of metal we place a cam or eccentric upon a shaft working in suitable bearings,
and we connect said pieces of metal together by side links or other suitable
means. Upon one end of another shaft we place a fly wheel, and upon the
other end of said shaft we fix a strong pinion, which takes or gears into a
toothed wheel as much larger in diameter than said pinion as is necessary to
obtain the desired power; or we employ double sets of wheels when it is desired
to have considerable power, and upon the axis of motion of the larger wheel we
securely fix the aforesaid cain; thus it will be seen that upon motion being
imparted to said cam one tool will be raised and the other one lowered simul-
taneously. And it will readily be perceived that in adapting this press to the
purposes of stamping, coining, and embossing, it is only necessary to substitute
the proper tool in the place of the before-mentioned punch to enable these
several operations to be performed in one and the same machine. If necessary
the machine may be worked by a crank and treddle.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Flint, Thomas Wood, and Edward Wood in the
Great Seal Patent Office on the 1st April 1857..
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
FLINT, of Skinner Street, Bishopsgate" Without, in the City of London;

page_text: nistrators, and assigns, or such others as we, the said George Flint, Thomas
Wood, and Edward Wood, 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 IM-
PROVED PUNCHING PRESS OR MACHINE ADAPTED TO THE PURPOSES OF STAMPING,
COINING, SLOTTING, AND EMBOSSING, AND FOR CUTTING METAL AND OTHER SUB-
STANCES," upon the condition (amongst others) that we, the said George Flint,
Thomas Wood, and Edward Wood, our executors or administrators, by an
instrument in writing under 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 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 George Flint, Thomas Wood, and
Edward Wood, 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 in writing, and on reference to
the accompanying Drawings, that is to say:-
Our Invention consists, firstly, in so constructing a punching press or
machine as that the power is exerted from a cam or eccentric direct upon the
punching tool or other implement employed, through the agency of wheelwork
instead of through the medium of a lever or levers, as heretofore commonly
practised in presses or machines employed more particularly for cutting or
punching large holes in metal; and, secondly, in so arranging and constructing
the mechanism of such said press as that it shall occupy considerably less
space and be very much cheaper than ordinary punching presses or machines.
These improvements we effect by the following means:-Suppose, for example,
the press is required to perform the combined operations of cutting, metal
at one end of the press, and punching holes at the opposite end thereof,
we arrange the moveable cutting shears and the punch holder one above the
other in an upright recess formed in the stand or body of the press and capable
of sliding therein; between these two pieces of metal we place a cam or
eccentric upon a shaft working in suitable bearings, and we connect said pieces
of metal together by side links or other suitable means. Upon one end of
another shaft we place a fly wheel, and upon the other end of said shaft we fix
a strong pinion, which takes or gears into a toothed wheel as much larger in
diameter than said pinion as is necessary to obtain the desired power; or we

page_text: employ double sets of wheels when it is desired to have considerable power,
and upon the axis of motion of one of the wheels we securely fix the aforesaid
cam; thus it will be seen that upon motion being imparted to said cam one
tool will be raised and the other one lowered simultaneously. And it will
readily be perceived that in adapting this press to the purposes of stamping,
coining, embossing, &c., it is only necessary to substitute the proper tool in the
place of the before-mentioned punch to enable these several operations to be
performed in one and the same machine. The machine may be worked by
a crank and treddle, or by steam, or other motive power.
In order to explain our said Invention as completely as possible, we now
proceed to describe the best means we are acquainted with for carrying the
same into practical effect, reference being had to the illustrative Sheet of
Drawings hereunto annexed, and to the numeral figures and letters of reference
marked thereon respectively, as follows.
DESCRIPTION OF THE DRAWING.
Figure 1 is a front elevation of one form of construction of our improved
press for cutting and punching metal, and more particularly adapted for heavy
work; Figure 2 is an elevation of the back of said machine; Figure 3 an edge
view thereof, at A, Figures 1 and 2; Figures 4, 5, 6, & 7 represent detached
portions, herein-after particularly described and referred to. At each of the
foregoing Figures we employ similar letters of reference to denote corresponding
parts, in so far as such parts appear or can be seen at each of such said Figures
respectively.
At Figures 1, 2, 3, A, A, is a casting supporting the following parts, which
are connected thereto, and operate upon each other, as follows:-B, C, D, are
short shafts of wrought iron, upon which are respectively fixed the pinions and
spur wheels G, II, I, and fly wheel F; and K is a spur wheel, mounted and
revolving upon a fixed wrought-iron stud E. The upper part of the casting A
has a rectangular-shaped recess formed true therein to receive the square part
of a shear holder M, said square part being securely held in said recess by a
plate N, fixed to the casting A by screws at a, a, and by screws b, b, at each
side of the casting A, as at Figure 3. The lower part of the casting A is like-
wise formed with a rectangular-shaped opening therein to receive another and
lower shear holder O, punch holder P, and cam Q, said cam being fixed to or
formed upon the shaft D. The parts O and P are connected together by a s
hooked link c, shewn at Figure 4, the hooked parts thereof taking into holes
formed in parts O and P, as exhibited at Figure 5, and being kept therein by
forced pressure of the spring d against. said link. e is a pin passing through a

page_text: hole in the end of the casting A, as at Figure 3; one end of the pin e is formed
dovetailed (as at Figure 4), and such part fits in a corresponding shaped
groove formed in the edge of the link c, so that upon pulling back the pin e by
the knob thereof the hooked part of the link will be drawn out of one of the
holes in the piece O, which is necessary to enable the workman to reverse the
position of the cutting shears, as occasion may require. The position of
the upper shear may also be reversed by slackening the screws b, b; the
cutting shears are connected to the shear holders by screws, as at Figure 6, at
which said Figure these parts are represented drawn to an enlarged scale.
At Figures 2, 3, 7, R is a plate for securely holding the lower shear holder,
punch holder, cam, and link e in proper position, said plate R being securely.
fixed to the casting A by screws at Figure 2. The boss r of this plate also:
supports one end of the axis of the cam shaft D. S is a die holder; and sa
tempered steel die fitting therein, and having a hole formed therein corre-
sponding in size with the diameter of the punch in the punch holder. These
punches and dies may be readily removed, and others either larger or smaller
substituted in their places. The die holder S is securely connected to and
adjusted in the lower part of the casting A by keys or wedges f. f. T, T, are
small running wheels mounted upon axles fixed to the bottom of the casting A,
and employed for transporting the machine from place to place.
OPERATIONS OF THE MACHINE.
The machine, when required to be worked by manual power, may have a
handle fixed in the slot t, formed in one of the arms of the fly wheel F, as at
Figure 1, so that by imparting rotatory motion to said fly wheel, such motion
will be transmitted through the agency of the several wheels and pinions to the
cam Q, the effect of which will be to raise and lower the moveable cutting
shear and punch, and to punch or cut, as the case may be, a considerable
thickness of any metallic substance placed between the cutting shears and
punch and die with comparatively little exertion of the operator. When the
above machine is required to be used for light work, we then throw the pinion
G out of gear with the wheel H by any convenient means, and affix a bandle
in the slot u of the wheel E, by which we obtain sufficient power, and increase
the speed of the machine. We would also remark, that when it is desired to
work the machine otherwise than by manual power, the same may be effected
by placing a fast and loose pulley upon the shaft B, and passing a strap or
band around the same, in connection with a steam engine or other motive
power machine.
Having now fully described and set forth the nature and object of our said

page_text: Invention of "An Improved Punching Press or Machine, adapted to the
Purposes of Stamping, Coining, Slotting, and Embossing, and for Cutting
Metal and other Substances,". together with the best means we are acquainted
with for carrying the same. into practical effect, we would remark, in conclusion,
that we do not claim the exclusive use of any of the separate parts above men-
tioned and referred to, except in so far as the same may be employed in
combination and for the purposes of our said Invention, neither do we limit or
confine ourselves to the precise tools named, as other tools might be substituted
and used with equal advantage, such as a rivetting tool, or a slotting tool, or a
tool for cutting six-sided nuts out of bar iron; and we reserve to ourselves the
right of making such modifications in the construction of the above machine
as are consistent with the character of our said Invention.
In witness whereof, we, the said George Flint, Thomas Wood, and
Edward Wood, have hereunto set our bands and seals, this Thirty-
first day of March, in the year of our Lord One thousand eight hundred
and fifty-seven.
