Leeds, in the County of York, Machinery Merchant, for the Inven-
tion of "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR PUNCHING,
PROVISIONAL SPECIFICATION left by the said Benjamin Miller at
the Office of the Commissioners of Patents, with his Petition, on
the 16th November 1872.
I, BENJAMIN MILLER, of Sheaf Works, Hunslet Road, Leeds, in the
County of York, Machinery Merchant, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
PUNCHING, CUTTING, SHEARING, ANd Planing IRON OR OTHER METALS," to be as
follows, that is to say :-
My Invention relates to employing a self-acting punching and
shearing machine so arranged that it will punch, cut, shear, and plane
circular, curved, straight, or angular plates of iron or of any other

page_text: metal to any required form. For this purpose I employ an ordinary
double-sided punching and shearing machine, and in a line with the
front of the machine I bolt a bed similar to that of a planing machine
with V grooves. On this bed is placed a sliding table, on the under side of
which are V slides fitting into the grooves in the bed on which they
slide. Plain grooves are formed in the table for the purpose of
securing and bolting any plates to be operated upon, and underneath is
fixed a nut receiving a screw, which revolving right or left causes the
table to move forward or backwards and receives its motion in the
following manner :-On the boss of the main wheel is fixed a path cam
giving motion to a lever. One end of this lever carries a friction pulley
working in the path of the cam. At the other end is a radial slot into
which is fitted a stud made to slide in it to enable the altering of the
stroke of another lever with which it is connected. This lever is
actuated by a rod and stud, and is fixed horizontally on a cross shaft,
into which is attached a vertical lever connected by a rod to another
vertical lever, which is loose on a short shaft near the end of the
machine. This lever carries a paul giving motion to a ratchet wheel
working a shaft, on which at the other end is fixed by means of a key
and nut a change spur wheel. Working in this change spur wheel is an
intermediate wheel revolving on a stud movable in a radial slot to suit
the various sizes of change wheels. This intermediate wheel gears into
another wheel keyed to a short cross shaft at the end of the machine.
On one end of this cross shaft is keyed a bevel wheel working a pinion
on the end of the screw giving motion to the table.
On the other side of the machine is fixed a short bed at right angles to
the one herein-before described. This bed, which is <'d outwards at the
top, carries a slide having a stud fixed in the centre, and above supporting
a worm wheel, attached to which is a circular table. On this circular
table is fixed the plate to be operated on. This circular table receives its
motion through a vertical lever fitted on the end of the cross shaft
which passes the end of the short bed carrying the slide, worm wheel,
and circular table herein-before described. This vertical lever is con-
nected by means of a rod and two studs with a ratchet lever, on which
is attached a paul working a ratchet wheel fitted in a stud. On this
stud and fixed to the ratchet wheel is a spur wheel gearing into an
intermediate wheel, which gears into a change pinion fixed on the end
of the worm shaft actuating the worm and circular table.

page_text: The circular table is fixed on the slide to allow of any required radius
to cut, punch, or plane the plates in straight, curved, or angular lines as
follows:-
Two moveable angular levers fixed on studs are fitted to the travelling
table at a suitable distance to allow of the taking in of the plates to be
operated on. On the end of one arm of each of these angular levers is
a slot in which is fitted a sliding block. In the centre of this block
passes a pin or stud fixed to the vice or blocks holding the plates to be
operated upon.
On the top of the vice or blocks fixed by means of set screws is a
template acting as a guide to the plate to be punched, cut, sheared, or
planed as it travels by means of each stroke of the screw. The other
ends of the angular levers are attached by a rod passing from one to the
other in such a manner that the levers can be placed nearer to or further
from each other to suit the length of the plate.
I also employ two parallel guide bars on which the ends of the vice
or blocks slide to prevent the plate moving longitudinally only with the
table.
I can also punch, cut, shear, or plane on either side of the machine,
as the sides carrying the punch or shear are set at an angle for the
purpose of punching, cutting, shearing, or planing a plate at any
angle.
The machine being self-acting and easy to adjust does not require the
assistance of skilled labor. To this machine I connect a steam engine
with variable expansion valve to allow of regulating the steam according
to the work to be done.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Benjamin Miller in the Great Seal Patent Office
on the 16th May 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENJAMIN
MILLER, of Sheaf Works, Hunslet Road, Leeds, in the County of
York, Machinery Merchant, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixteenth day of November, in the year

page_text: of our Lord One thousand eight hundred and seventy-two, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Benjamin Miller, Her special licence that
I, the said Benjamin Miller, my executors, administrators, and assigns,
or such others as I, the said Benjamin Miller, my executors, adminis-
trators, 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 "IMPROVEMENTS IN MACHINERY
OR APPARATUS FOR PUNCHING, CUTTING, SHEARING, AND PLANING IRON OR OTHER
METALS," upon the condition (amongst others) that I, the said Benjamin
Miller, 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 Benjamin Miller, do hereby declare
the nature of my 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 hereto
annexed, and to the figures and letters marked thereon, that is to
say :-
The said Invention relates to employing a self-acting punching and
shearing machine so arranged that it will punch, cut, shear, and plane
circular, curved, straight, or angular plates of iron or of any other metal
to any required form. For this purpose I employ an ordinary double-sided
punching and shearing machine, and in a line with the front of the machine
I bolt a bed similar to that of a planing machine with V grooves. On
this bed is placed a sliding table, on the under sides of which are V slides
fitting into the grooves in the bed on which they slide. Plain ↓ grooves
are formed in the table for the purpose of securing and bolting the
plates to be operated upon, and underneath is fixed a nut, receiving a
screw, which revolving right or left causes the table to move forward or
backward and receives its motion in the following manner:-On the boss
of the main wheel is fixed a path cam giving motion to a lever. One
end of this lever carries a friction pulley working in the path of the

or planed, as it travels by means of each stroke of the screw.
other ends of the angular levers are attached by a rod passing from
one to the other in such a manner that the levers can be placed
nearer to or further from each other to suit the length of the plate.
I also employ two parallel guide bars on which the ends of the vice
or blocks slide, to prevent the plate moving longitudinally only with the
table.
I can also punch, cut, shear, or plane on either side of the machine,
as the sides carrying the punch or shear are set at an angle for the pur-
pose of punching, cutting, shearing, or planing a plate at any angle.
The machine being self-acting and casy to adjust does not require the
assistance of skilled labor. To this machine I attach a steam engine
with variable expansion valve to enable the regulating of steam accord-
ing to the work to be done.
But in order that my improvements may be better understood I will
proceed to describe the same by reference to the accompanying Drawings,
in which Figure 1, Sheet 1, represents a front elevation of the self-
acting punching and shearing machine; Figure 2, Sheet 2, end cleva-
tion; Figure 3, Sheet 3, back elevation; and Figure 4, Sheet 4, plan of
the same. These Figures are all drawn to the same scale; all the
other Figures are drawn to a scale of double size.

page_text: Similar letters of reference are used in all the Figures to represent
similar parts.
A is a path cam cast on the wheel 1, in which travels a friction
pulley C revolving on a stud fixed at the end of the lever B. At the
other end of this lever is formed a curved slot, into which is fitted a
stud. One end of the rod D is fitted on this stud, and the other end is
attached by a stud to the horizontal lever F, the boss of this lever being
keyed on the rocking shaft B*. On this shaft is also keyed a vertical
lever E fixed to the rod G by a stud. The other end of this rod is
attached to the pawl lever H actuating the ratchet wheel N³. On the
boss of this ratchet wheel is keyed a spur wheel I, in which works an
intermediate wheel K revolving on a stud, which moves in a curved slot
to suit any size of change wheel required. In the intermediate wheel K
is geared a change pinion J fixed on the end of the cross shaft C'. This
pinion carries the shaft round by means of a clutch keyed on the end of
the shaft in such a manner as to allow it to slide into gear with a clutch
fitted or cast on the boss of the pinion J. At the other end of the cross
shaft C is fixed a bevil wheel M gearing into a pinion L keyed on the
end of the dividing screw O, which passes through a nut made in two
parts S and T³, Figures 6 and 7, Sheet 4. These parts S³ and T are
fitted in two sliding blocks R' and U³, and are fixed in a box V³, and can
be opened or closed by means of the handle Y³, keyed on the shaft,
W being a projection from the plate having the curved slots X³, through
which pass two pins, one of which is fixed in the top sliding block R³
and the other in the bottom block U³, so that when the handle Y³ is
moved to the right or left the nut opens or closes, and thus grips or
releases the screw as may be required. The box V8 into which the
sliding blocks Rand U³ are fitted is secured to the rib M³ cast on the
travelling table O³, so that when the screw revolves if the nut S³, T³, is
closed the table O' is carried forward.
The threads of the screw O are V shaped, so that when the brass
nut S and T is worn or becomes slack a little may be filed off the edge
of the brass, and a thin packing put at the back of each to make up for
the thickness filed off. This arrangement is rendered necessary to allow
the screw to divide accurately and stop at regular intervals. To bring
back the table after it has travelled the required distance of the plate
operated on another screw P is used, which is driven by a belt from the
drum H³ actuating a pulley D' keyed on the shaft F. On this shaft is

page_text: also fixed a wheel D' working in an intermediate wheel E' actuating the
wheel F³, which being keyed fast to the shaft G' causes it to revolve.
On the end of the shaft G+ is fitted a bevil wheel R gearing into another
bevil wheel Q keyed on the end of the screw P, causing it to revolve.
The nut in which the screw P works is made in two parts, each part
being moveable, and are so arranged as to move simultaneously in
opposite directions by means of the two eccentrics P³ and Q³, Figures 6
and 9, Sheet 4. They pass through the upper and lower portions of the
sliding blocks Z³, and are connected at one end by three wheels, two of
which, A² and C³, are keyed on their axles, motion being conveyed from
one to the other by the intermediate wheel B. On the other end of the
axle of the top eccentric P³ is keyed a skew wheel gearing into another
skew wheel keyed on the shaft E². This shaft is carried by brackets
fixed under the table to ribs D². These ribs are cast under the table the
whole length. At the end of the shaft E³, which projects past the end
of the table, is fitted a head or collar in which are four holes; they are
for the purpose of inserting a rod to turn the shaft round to open or close
the nut.
The two sliding blocks Z³ carrying the two halves of the brass nut are
fitted into a box, the two ribs cast under the table forming the sides;
the ends are formed by bosses through which the screw P passes.
When the table has been worked as far as required by the dividing
screw the handle Ys must be turned to release the screw, which is effected
by opening the nut. The dividing screw O being released the shaft E*
is turned until the nut is closed on the screw P; the driving belt is then
thrown on the pulley D', giving a quick return.
The tooth plates I' at each end of the table are for the purpose of
ascertaining if the nut and screw are in such a position as to allow the nut
to go into its place. Should the teeth of one of the plates drop freely into
the spaces of the screw the nut may be closed, if not the table will have
to be moved by turning the dividing screw O until the teeth drop into
the spaces. The dividing screw ○ can be turned by hand by putting a
lever on the square end of the cross shaft C* and turning it round.
The middle pulley U on the shaft F is loose and simply revolves on
the shaft when the table is not required to move.
The wheel T is keyed
on the boss of the pulley C. This pulley runs loose on the shaft. The
wheel gears into the wheel S, which is keyed on the shaft G', the com-

page_text: munication from this shaft to the screw being the same as herein-before
described for the return of the table, the object of this motion being to
propel the table forward so as to bring it into a position to plane the
edges of the plates.
The flat bar H, on which is fixed the belt fork V, is connected at one
end with the L lever Z by a slot in the bar through which one end of the
lever passes in such a manner that when the handle E' is moved it
causes the bar to slide, actuating the belt fork V, between which the
bolt passes, throwing it on to any of the pullies according to the way in
which the table is required to move. Should the table be required to
move forward the belt will have to be thrown on the pulley C*, if back-
ward on the pulley D'. At the other end of the belt bar H* is a vertical
lever I' having a weight J' at the top. On the bottom end of the
vertical lever I' is fitted a stud passing through the belt bar. On the
top of the stand Y carrying the L lever Z is an arm having three holes.
The two end holes receive a pin acting as stops to the handle E*, pre-
venting it being pushed too far either way. The middle arm is bored
through and also the lever, in which a pin is passed to keep the arm in
its place when the belt is on the loose pulley.
Another flat bar X running the length of the bed of the machine is
connected at one end with the L lever Z by a swivel stud, through which
it
passes and is fixed. On the under side of the swivel stud is fitted a
pin passing through the lever in such a manner that when the sliding
bar X is moved it actuates the belt bar and gear. On the sliding bar X
are fixed two moveable dogs, which coming in contact with a projection
on the table causes the bar to slide, reversing the action of the table;
but the action of the L lever Z is not sufficient to reverse the machine,
it is therefore assisted by a vertical lever I* and weight J*.
R' is a template or guide slot representing the line of holes to be
punched or form of plate to be cut. In the slot runs a friction
pulley W revolving on a stud fixed on a projecting bracket V¹, which
is bolted to the front of the machine. The ends of the guide plate are
secured to two blocks C¹ and E', having openings to receive the plate I¹
to be either cut or punched. This plate is secured by set screws E.
Underneath the blocks C¹ and E' are pins passing through them and
fitting in slots in the levers D¹ and F¹ (Figure 12, Sheet 5). These pins
also fit into straight slots made in the parallel bars 1³. These parallel
bars are secured to the table by means of bolts passing through slots cast

page_text: in the table extending from one end to the other, allowing the parallel
bars to be secured at any part of the table to suit the length of plate to
be operated on. These bars are connected at the other end by a rod J³,
one end of which is attached to the end Ns of the lever F¹ by a pin. A
swiveling stud is fitted at the end L³ of another lever, through which the 5
rod passes, and is fixed to any required position by the set screw M³.
The parallel motion is for the purpose of giving the required form to
the plate to be cut or line of holes to be punched according to the guide
or template. When the curve is small it is not required to have a slot
for the guide pulley W₁ to run in, as one end of the template will be 1
sufficient. The edge is kept against the guide pulley W₁ by the
spring L, thrusting it against the bracket at M, which is secured to the
travelling table and the collar N₁, fixed on the rod J³ so as always to
press the edge of the template against the guide pulley W.
For cutting circular plates or punching holes in a circle I employ a 1
lever C³ fixed on a shaft B' which is connected to the pawl lever W* by
the rod S*. The pawl works the ratchet wheel V2, on the boss of which
is keyed a spur wheel U2 working in an intermediate wheel T. This
wheel revolves on a moveable stud working in a curved slot to suit any
size of change wheel that may be required. The change wheel gears 2
with the intermediate wheel T, and is fitted on the end of the worm
shaft. On the boss of the change wheel is a clutch fitting in another
clutch keyed on the shaft. These clutches slide into gear one with the
other, and the change wheel runs loose on the shaft when not in gear,
but when the clutches are in gear and the ratchet wheel is pushed for- 2
ward by the pawl, motion is given to the worm wheel P' through the
wheels communicating between the ratchet wheel and the worm shaft.
Fixed on the top side of the worm wheel P is the circular table B³. On
the top of this table is fixed by cramps or other suitable apparatus the
plate to be operated on. The screw T4 serves to work the slide, worm 3
wheel, and table nearer to or further from the cutting or punching tool
to permit of cutting or punching large or small diameters.
For planing the edges of plates I employ a stand X2, in which is fitted
aslide, in which slides the tool carrier, which consists in a vertical
block H² fixed in a horizontal slide fitting the V slide. In the block H³ 3
is fitted a vertical slide V*, in which is fixed an ordinary planing machine
tool box. The vertical slide V* is worked by a screw I² carrying the tool
up and down, but this tool is worked in and out by the screw R* to allow

page_text: the cutting of a plate, which is effected by turning the hand wheel N°
keyed on the end of the screw R'. The nut through which this screw
works is in two parts, and can be opened or closed by the handle L³. A
bar G passes through the block H2 sliding through brackets fitted on
each side. The bolts securing the bar to the brackets pass through slots
made in the bar, allowing the bar to slide, and is drawn in or out by
the hand wheel K². At the other end of the bar is fitted a friction
pulley Q suspended from the under side by a stud on which it revolves.
This arrangement is for the purpose of planing curves.
The plate to be planed is fixed on the machine with the template or
guide and actuated by the guide pulley Q' working in a guide slot. As
the plate and template move forward the cutting tool is guided to the
required form, the screw R having first been released by opening
the nut, leaving the tool at liberty to move as guided by the guide
plate R².
Figures 10 and 11, Sheet 4, represent a different arrangement for
working the table to the one herein-before described with the screw and
change wheels. A lever V* is connected with the lever E by the rod G
(Figure 1, Sheet 1) and is placed at one end of the shaft Y*. At the
other end is fitted a lever W, in which is cut a slot fitted with a stud which
is fixed to the end of the rod X. The other end of this rod is attached
to a bar T by a stud. This bar is supported by two brackets Z* fixed to
the bed of the machine. Underneath the table O³ is a rack, in which
works one end of the lever U³. This lever is fixed to the bar T by a
stud, the action being as follows:-The lever W* actuates the bar carry-
ing the table forward by means of the lever U³ pushing against the
teeth of the rack, but the table is left in its place while the plate it
carries is being cut or punched, the bar returning to its former position.
R³ are friction rollers on which the table runs instead of sliding in
V grooves. These rollers are held in their positions by two iron plates S³,
through which pass the axles of the rollers. The plates are secured
together by bolts and work backward and forward with the table.
Figures 12, 13, and 14, Sheet 5, represent an adjusting apparatus to
divide curved lines into equal parts; v, punch; w, slot plate in which is
fixed a socket; this socket is moveable in the slot, and may be fixed at
any part of the slot by the nut e. Through this socket passes the pin y,
pointed at the bottom and having a flat head at the top. * is a spring
by which the pin is raised and kept up. The slot plate w is fixed to the

page_text: machine by a bracket bolted to the back of the punch, and a round
plate is fitted at the end of this bracket near the punch, under which
is fixed the slot plate w by three bolts d' in circular slots in such a
manner that the plate may move round the punch. On the top of the
socket above the nut is fixed one end of the guide plate 1. Through this
plate is a slot u, into which passes the guide pin a'. This pin is fixed to
the bracket V (Figure 14, Sheet 5). At the other end of this guide
plate is a guide pulley m. This pulley also fits the guide slot R2, allow-
ing it as it moves forward to draw the pin y into the line of holes being
punched, therefore when a hole has been punched and the plate carried
forward by the dividing screw the point of the pin y enters and is forced
down by the slide 4 coming in contact with the head of the pin, which
being of a taper form forces the plate to travel the exact distance between
the holes. This operation must be completed before the punch comes in
contact with the plate. On the return of the slide 4 upwards the pin is
released and drawn out of the hole by the spring 2. During the last
operation the table remains stationary and the levers I³ move with the
plate. a is a spur wheel fixed in front of the machine on a stud b
(Figure 13, Sheet 5). At the back of the spur wheel a is cast a rim
fitted with a break S. The springs and screw t are for the purpose of
regulating the amount of break power required. The lever ends of each
of the break bars are attached by a stud c to a fork h¹ suspended from
the stud b. On one of the break bars is cast an arm d, and which is
bolted on the slide 4 through the boss e. The spur wheel a works a
rack n, having one end connected with the lever o, having a boss keyed
at one end p to the axle of the eccentric q, fixing the plate and the
lever Is to the table, and securing it when the pin y has been forced into
the last hole punched.
Before the pin y enters the hole the projection e presses down the
lever d and with it the wheel a, bringing the rack n in the direction of
the arrow, drawing also the lever o, turning the eccentric q, and
liberating the lever I³, so that the taper pin y may easily be pressed into
the hole last punched. On the other break bar is cast a projection on
which the spring / presses. This projection rests on a stop g. The
spring is for the purpose of bringing the wheel and rack back again
with the slide and projection e, locking the lever I³, leaving it in position
to be moved forward with the table by means of the dividing screw when
the punch has been withdrawn.

page_text: Figures 15, 16, and 17 (Sheet 6) represent another dividing arrange-
ment. In the path cam A on the boss of the wheel I, herein-before
described, travels the friction pulley C fitted on the end of the lever B.
The other end of this lever has a slot, in which is fitted a stud having the
rod D fitted to it. The other end of this rod works on a stud fitted into
the slot of the lever F. This lever is keyed on the shaft B*, also the
lever E, which is attached to the rod G by a shackle joint. This rod is
in two parts and joined by a long nut and secured by two lock nuts.
This arrangement is for the purpose of lengthening the rod when
required to suit the position of the lever a to which it is attached by a
shackle joint. The lever a is attached by a stud to the link ỗ by which
it is supported, the link being fitted in the hanger j, which is bolted to
the machine, the top of the hanger having slot holes to allow of its being
removed when required.
A spring c is fixed on the same stud carrying the lever a and vibrates
with it. The other end of the lever a forms a socket for the pin d, so
that when a hole has been punched the pin is pressed into it by the
spring c, and when in this position the cam A operating on the levers
moves the plate operated on and the table on which it is fixed the dis-
tance required. The table and plate having moved the distance the levers
are set apart release the pin d from the hole by the pin and spring being
raised by the lever f (on one end of which is formed a projection u)
actuated by the slide 4 coming down on it and depressing the end with
the projection and raising the other end spring c and pin d. The cam
then moves the pin to the next hole punched, into which it drops ready
to again draw the plate when the punch is withdrawn from the last hole
punched. is a pulley fitting into the guide slot R³, and is attached to
the plate e by a stud. This plate is for the purpose of guiding the pin d
into the hole for drawing the plate operated on. This plate e has a slot
in it, so that the pulley 7 can be set to any convenient position, also for
receiving the two guide pins m which are fixed to the bracket V¹. The
slot is for the purpose of allowing the plate e to move as guided by the
guide slot R².
Under the front edge of the travelling table is cast or fitted a rack s
worked by the pawl o, which is actuated by the lever w fitted on a stud,
which is secured to the bed t of the machine. The lever v is a continua-
tion of the pawl o, and is for the purpose of enabling the operator to
draw it out of gear with the rack s when not required. This apparatus

page_text: is for moving the table by hand. The lever v is raised and placed on the
pin when not required. p is a spring to press the pawl against the rack
when it is in operation.
The same arrangement is used for dividing circular plates; the bars Is
simply act as parallel bars, and are bolted at each end to the travelling
table.
Having thus described my improvements and the best means I am
acquainted with for carrying the same into effect, I would have it under-
stood that I do not confine myself to the precise details shewn and
described, as these may be varied without departing from the peculiar 1
character of the Invention, but what I do claim is,—
Firstly. The general arrangement of a self-acting punching, shearing,
and planing machine, so arranged that it will punch, cut, shear, and
plane circular, curved, straight, or angular plates to any required
form, substantially as described and represented in the accompanying 1
Drawings.
Secondly. The mode or method of obtaining a compound motion
moving the plates operated on in any rectilinear or angular direction, as
herein-before described.
Thirdly. The adjusting arrangements for dividing curves into equal 2
parts, substantially as described and represented in Sheets 4, 5, and 6 of
the accompanying Drawings.
In witness whereof, I, the said Benjamin Miller, have hereto set my
hand and seal, this Fifteenth day of May, in the year of our
Lord One thousand eight hundred and seventy-three.
