Year: 1864

page_text: LETTERS PATENT to Charles Wetherell Wardle, of Leeds, in the County
of York, Mechanical Engineer, Partner in the Firm of Manning, Wardle,
and Company, and Robert McIntyre, of Leeds, aforesaid, Manager for
the said Firm, for the Invention of "IMPROVEMENTS IN APPARATUS FOR
CUTTING, BORING, SLOTTING, OR DRILLING METALLIC OR OTHER SUBSTANCES."
PROVISIONAL SPECIFICATION left by the said Charles Wetherell Wardle
and Robert M°Intyre at the Office of the Commissioners of Patents,
with their Petition, on the 2nd November 1864.
We, CHARLES WETHERELL WARDLE, of Leeds, in the County of York,
Mechanical Engineer, Partner in the Firm of Manning, Wardle, and Com-
pany, and ROBERT MINTYRE, of Leeds aforesaid, Manager for the said Firm,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUS FOR CUTTING, BORING, SLOTTING, OR DRILLING METALLIC OR OTHER
SUBSTANCES," to be as follows:-
The metal or substance to be cut, bored, slotted, or drilled is fixed on a
table, by means of which it is kept in the proper position under the tool in
some of the ordinary ways. To this table two movements are communicated
in a horizontal direction, the one longitudinal and the other circular, the two
resulting in a curvilinear movement of the table, and the metal or substance

page_text: fixed upon it in such a manner that by adjusting the two movements a great
variety of curves may be produced by the same machine. The longitudinal
movement is produced by a rack or any other of the ordinary mechanical
appliances.
One advantageous mode of obtaining the longitudinal motion is by
attaching the appliances for producing it to a table below that on which
the metallic or other substance is fixed, and which is fixed to the last-named
table by a vertical axis, on which the upper table is free to revolve, but with-
out changing the relative position of their respective centres or other points to
which such axis may be affixed. The circular movement is produced by a
radial arm fixed rigidly to the table on which the metallic or other substance
is fixed, which radial arm is attached to and regulated by a guide. This guide
may be adjusted to any required angle by means of a graduated segment of a
circle, to which it is attached by fixing the guide at that point of the graduated
segment on which is marked the number of degrees of such angle. By regu-
lating the length of the radial arm and the angle of the guide a combination
of the longitudinal and circular movements is produced, by means of which
any required curve in the line of holes to be punched or the surface of the
material to be cut, slotted, or drilled may be obtained.
The novelty of the Invention consists in the combination of the longitudinal
and circular movements before described, so as to produce any required curve
with the same machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Wetherell Wardle and Robert M'Intyre in the Great
Seal Patent Office on the 2nd May 1865.

of Great Britain and Ireland, the Channel Islands, and Isle of Man, an
Invention for "IMPROVEMENTS IN APPARATUS FOR CUTTING, BORING, SLOTTING, OR
DRILLING METALLIC OR OTHER SUBSTANCES," upon the condition (amongst others)
that we, the said Charles Wetherell Wardle and Robert M.Intyre; by an
instrument in writing under our hands and seals, or under the hand and seal
of one of us, 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.
KNOW KNOW YE, that we, the said Charles Wetherell Wardle and
Robert McIntyre 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, reference being had to the
Drawings hereunto annexed, and to the letters and figures marked thereon
(that is to say):-
Our Invention of improvements in apparatus for cutting; boring, slotting, or
drilling metallic or other substances has for its object to construct the table
(upon which the metal or other substance to be operated upon is secured) in
such a manner that it may be turned or manœuvred in any direction, so as to
cut, bore, punch, drill, or form holes in the metal or other substance in a
curvilinear direction.
The metal or substance to be operated upon is fixed in any convenient
manner on a table, by means of which it is kept in the proper position under
the tool. To this table two movements are communicated in a horizontal
direction, the one longitudinal, the other rotary, so that by the compound motion
a curvilinear movement of the table and the metal or substance fixed upon it
may be obtained. By adjusting the two movements in combination a variety
of curves may be produced by the same machine. The longitudinal movement
is produced by a rack or any other equivalent and well known mechanical,
appliance.
A convenient mode of obtaining the longitudinal motion is by attaching.the.
appliances for producing it to a table or carriage below that on which the
metallic or other substance is fixed. This lower table or carriage is fixed or
connected to the upper table by a vertical axis on which the upper table is.
free to revolve, but without changing the relative position of their respective

page_text: centres or other points to which such axis may be connected. The rotary
movement of the upper table is produced by a radial arm fixed rigidly to it,
which radial arm is attached to a block working within a guide. The guide
may be adjusted to any required angle by means of a graduated segment of a
circle, to which it is carried by fixing it at that point of the segment on which
is marked the number of degrees of angle required. By regulating the length
of the radial arm and the angle of the guide a combination of the longitudinal
and rotary movements is produced, by means whereof any required curve in
the line of holes to be punched or the surface of the material to be operated
upon may be obtained.
In the accompanying Drawings Fig. 1 represents a plan view of the
Invention as applied to a punching machine (but with the upper table
removed); Fig. 2 is a longitudinal sectional view on the line A, B, of the
plan view; Fig. 8 is an end elevation looking from A of the plan view; and,
Fig. 4 is a transverse section on the line E, F, of the plan view looking
from B.
A, A, are the driving pulleys which turn the toothed wheels B, and thereby
actuate the taker-off C and punching lever D, as in the ordinary punching
machines; E is a crank, to which is connected the rod F, the lower end of
which is fixed to a lever (see Fig. 4) attached to and actuating the rocking
shaft G. At the end of this rocking shaft is a toothed pinion H gearing into
a rack I, which is cast upon or fastened to the under side of the oblique pin
rack K. The oblique pin rack is made to work backwards and forwards for
a short adjustable distance, and is supported by and works within the slides or
guides L fixed on each side of the gantry M of the machine. Upon the upper
side of the oblique pin rack are studs or pins at intervals to serve the purpose of
ordinary teeth or cogs; N is a carriage or table which runs upon the gantry
M; the wheels carrying it being on one side grooved or V-shaped to suit the
V-shaped rail of that side of the gantry, whilst the wheels on the other side
are ordinary wheels to suit the flat rail of the other side of the gantry.
Underneath the carriage or table N, and suitably mounted in brackets is a
pawl or catch O, nearly extending across the space between the sides of the
gantry. The nose of this elongated pawl or catch is made so that it will drop
between the studs or pins of the oblique pin rack by its own weight. P is a
short arm or tail piece (Figures 2 and 4) projecting from the back of the pawl
or catch; R is a rod fixed in suitable brackets, one end of which extends.
from the side of the machine and is provided with a handle; at the other end
of this rod is a projection or lug which is tapered or inclined on its inner part..
When the rod is drawn out by hand the inclined projection or lug comes in

page_text: contact with the tail piece, and thereby lifts the pawl or catch O out of contact
with the studs or pins on the oblique pin rack. When the pawl or catch is
out of contact with the pin rack the carriage and the table above it can be
moved to any part of the gantry by means of the wheels and handle 1, 2, 3,
and 4 (Fig. 1). S is a table or plate resting upon and carried by the carriage
or table N. The table or plate S is centred upon a gudgeon or swivel pin U,
and consequently a rotary motion about its centre and in a horizontal direction
can be given to it. At one end of the upper table or plate, and cast upon or
fixed to it is a pendent bracket V, to which is rigidly attached the arm W
(Fig. 2), which is carried to the sliding block X, and which arm W may be of
any convenient length. The block X slides within the radial guide Z, which
is represented in the Drawing as being straight, but it may be made and
applied of any desirable form. It is extended to the end of the gantry, and
for this purpose the gantry may be extended also to suit the required length
of guide. One end of the radial guide is connected by the arm a¹ to a stud
pin 6', which is fixed to the gantry, and is free to move round the said pin.
It will therefore be seen that the upper table or plate on which is placed the
material to be operated upon is connected to the sliding block X moving
within the radial guide Z. The extreme end of that part of the gantry
which receives the radial guide Z and sliding block X is shaped so as to form
the segment of a circle, and has a graduated scale marked upon it. The
radial guide extends to and rests upon or works within this segment, and can
be adjusted to any of the degrees marked upon it. When adjusted it is
fastened down by the bolts c², or in any other convenient manner. d³, d³, are
slots for the radial guide to be more effectually moved or shifted to position
and held firmly whilst the machine is working. The carriage or lower
table N moves straight along the rails of the gantry. The upper table or
plate S moves also along with the carriage or lower table, to which it is con-
nected by the gudgeon or swivel pin U, but has an independent axial motion
upon it. The plates of metal to be punched are placed upon the upper table
or plate S, and firmly clamped or bolted to it by the clamps and bolts e, e²,
(Fig. 3) or in any other suitable manner.
When the machine is working the toothed pinion H fixed on the rocking
shaft G actuates the rack I fastened beneath the oblique pin rack K, which
will therefore be alternately moved backwards and forwards. If in a backward
direction, or in the direction shewn by the arrow in Fig. 1, the backward
traverse of the oblique pin rack allows the nose of the pawl or catch to pass
over the stud or projection upon the oblique pia rack, which is immediately
behind it. If in a forward direction the pawl or catch is set or blocked

page_text: against the stud or projection in front of it, and thereby forces the carriage or
lower table forward; a slow but regular traverse is therefore given to the
carriage or lower table along the gantry, and to the upper table or plate; and
the material under operation.
When the machine is fixed in position, as shewn in Fig. 1, that is with the
radial guide and sliding block fixed in the middle of the gantry, it is obvious
that both the upper table or plate and the carriage or lower table will move
mutually in one and the same direction, and a straight line of holes will be
punched by the machine. But when the radial arm Z is moved upon the
graduated segment or index plate a corresponding angular difference of
position between the upper table or plate and the carriage or lower table is
effected. As before stated the carriage or lower table moves straight forward
upon the gantry. The upper table or plate however, although moved forward
with the carriage or lower plate, moves round its axis in a direction cor-
responding to the angle at which the radial guide Z is fixed and to the block
or slide working within it, to which latter the upper table or plate is firmly
attached. The result of these combined motions is that a curvilinear move-
ment is imparted to the upper table or plate, the amount of curve corresponding
to the degrees which the radial guide is moved on the graduated segment.
It is evident from the foregoing description, that the Invention can be
applied to any machine where an adjustable curvilinear direction or movement
of the nature or character described is required.
Figs. 5 & 6 in the accompanying Drawing shew how the Invention may
be applied to a slotting machine. A is the ordinary top table; B, the ordinary
lower table, and C the working parts of a slotting machine. A is also the
upper table working according to this Invention. The movement angular to
the lower table is produced by the radial guide E, within or at the top of
which works the slide F, attached by the arm G to the upper table; H is the
regulating segment.
°
From the foregoing explanation of the Invention it will be evident that it
is applicable not only to machines for slotting, boring, drilling, or punching
merely, but to all machines where cutting, sawing, or other operations are
required to be performed in a curved direction analogous to or in the nature
of the operations above described.
We would observe that we do not confine ourselves to the precise mechanical
details above described, inasmuch as it is evident many other modes of working
the slide X and other parts to obtain the required angle of the upper table or
plate may be employed; but what we do claim as our Invention is the mode
herein set forth of obtaining a compound motion, so as to move the metal or

page_text: substance to be operated upon in any curvilinear direction which may be
found most suitable for the exigencies of the work to be performed,
In witness whereof, we, the said Charles Wetherell Wardle and Robert
M*Intyre, have hereunto set our hands and seals, the Twenty-ninth
day of April, in the year of our Lord One thousand eight hundred
and sixty-five.

Wetherell Wardle and Robert
M'Intyre, in the presence of
