Engineers, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN MACHINERY OR APPARATUS FOR PUNCHING, SHEARING, AND BURNISHING,"
to be as follows:-
This Invention consists in the employment of a circulur table having a long
boss mounted and capable of rotating upon a spindle fixed in suitable frame-
work. This table carries a series of punches and shears or cutting instruments,
which are in succession actuated as the table rotates by a cam fixed on the
said spindle, and by suitable springs attached thereto, and to a plate rotating
with the table. The table also carries a corresponding series of dies or
blocks for the punches and shears to act against. This table also carries a

page_text: series of burnishers or instruments for smoothing the holes when punched,
which have rotary motion given to them by pullies thereon rolling upon a
circular flange on the framing as the table rotates. These burnishers are
pressed into action by springs, and removed out of action by a cam or segment
of a circular flange with inclined ends, which comes into contact with a collar
on each of the burnishers in succession as they are carried around by the table.
This machine is especially adapted for punching and burnishing the holes,
and shearing or cutting into proper lengths, and. form the metallic healds for
which Letters Patent have been granted to Hudson Yeadon, Edwin Yeadon,
Samuel Yeadon, and John Yeadon, No. 992, dated the 21st day of April
1863, and is applicable to other similar purposes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Craven and Samson Fox in the Great Seal Patent
Office on the 22nd April 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN
CRAVEN and SAMSON Fox, of Leeds, in the County of York, Engineers, send
greeting.

Patent, bearing date the Twenty-second day of October, in the year of our
Lord One thousand eight hundred and sixty-three, in the twenty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and grant
unto us, the said John Craven and Samson Fox, Her special licence that we,
the said John Craven and Samson Fox, our executors, administrators, and
assigns, or such others as we, the said John Craven and Samson Fox, 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 "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR PUNCHING, SHEARING, AND BURNISHING," upon the condition
(amongst others) that we, the said John Craven and Samson Fox, our exe-
cutors or administrators, by an instrument in writing under our, or their,
or one of our or 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

page_text: Patent Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that we, the said John Craven and Samson Fox, 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, that is to say:-
The Invention consists in the employment of a circular table having a long
boss mounted and capable of rotating upon a spindle fixed in suitable frame-
work. This table carries a series of punches and shears or cutting instruments,
which are in succession actuated as the table rotates by a cam fixed on the
said spindle, and by suitable springs attached thereto, and to a plate rotating
with the table. The table also carries a corresponding series of dies or blocks
for the punches and shears to act against. This table also carries a series of
burnishers or instruments for smoothing the holes when punched, which have
rotary motion given to them by pullies thereon rolling upon a circular flange on
the framing as the table rotates. These burnishers are pressed into action by
springs, and removed out of action by a cam or segment of a circular flange
with inclined ends, which comes into contact with a collar on each of the
burnishers in succession as they are carried around by the table.
This machine is especially adapted for punching and burnishing the holes,
and shearing or cutting into proper lengths and form the metallic healds, for
which Letters Patent have been granted to Hudson Yeadon, Edwin Yeadon,
Samuel Yeadon, and John Yeadon, No. 992, dated the 21st day of April 1863,
and is applicable to other similar purposes.
In order that this Invention may be more clearly understood, we have given
reference to an accompanying Sheet of Drawings of a machine constructed
according to the said Invention, and adapted for manufacturing the metallic
healds herein-before referred to.
Fig. 1 is a plan, and Fig. 2 is an elevation (partly in section) of the same:
A is a circular frame, supported upon four legs, bolted to a bed plate B,
having a step or boss C in the centre, in which is fixed an upright or vertical
spindle D; mounted on this spindle is a circular table E, having a long boss;
which is capable of rotating freely thereon; F is a bevil wheel keyed on this
boss, which receives motion by pinion F and shaft F; on which are the
driving pullies F³. To the circular table E is attached a ring G, in which are
sixteen slide bars or spindles H capable of sliding. Eight of the said
spindles carry a punch I in each outer end, and the other eight each carry
two punches J, and one shear or cutting instrument K. A corresponding

page_text: number of blocks L and L' are also carried on the table for the punches and
cutters to act against. These punches and cutters are forced outwards into
action as the table rotates by the opposite ends of the spindles to where the
punches and cutters are fixed, moving over or being in contact with the
periphery of a cam M, which is fixed on the vertical spindle, and the said
punches are drawn out of action by spiral springs M¹ attached to the punch
spindles, and to a plate M² loose on the vertical spindle, and rotating with the
table. The table also carries a series of eight burnishers N, which receive
rotary motion by pullies or rollers N¹ fixed thereon, rolling on the circular
flange of the table. The surfaces of these rollers and flange are, by pre-
ference, fluted or formed into short teeth after the manner of pinion and rack;
but these surfaces, however, may be covered with leather or other suitable
substance to obtain friction without much pressure or lifting against the
bearings of the spindles. A small collar N2 is fixed on the end of each
burnisher, which collars run outside a cam or segment of a circular flange P
of the frame to keep them out of action during one part of the revolution of
the table, and then pass within another cam or circular flange Q, being pressed
into action by spiral springs N³ during the other part of the revolution. The
top of the vertical spindle is held firm by being fixed in a bracket R attached
to the outside of the frame, and the table is kept steady in motion by its long
boss passing through a bush in the top plate of the frame, as well as by the
vertical spindle on which it rotates. S is a segment of a drum attached to
the bracket, in the outer surface of which is a groove for conducting the
material to the punches and cutters, which is shewn in-detail at Fig. 3. The
single punch blocks L' are capable of sliding or being moved up and down in
the frame as the table rotates for the purpose of allowing the burnishers to
pass underneath, so as to smooth the opposite side of the hole to that which
the punch entered by a cam or segment of a circular rim T, which acts on
the pins U and lifts them, and by the springs V, which depress them. W is
a rotary spindle, ou which are a pair of disc nippers, which take hold on the
finished healds and throw them out of the machine in succession. This part
is shewn in section full size at Fig. 4. The punches and cutter, with a portion
of the spindle in which they are fixed, is shewn at Figs. 5 and 6 in action on
a portion of the material of which the healds are made, punching two boles
and cutting the material at the same time into lengths. Figs. 7 and 8 shew
the burnisher in action on one of the healds. The action of the machine is
as follows-The material is placed upon a winsel or drum, which may be
separate from the machine, and conducted thence in the direction shewn by

page_text: the flotted line and arrow X to the segment S, which guides it to a groove
provided to conduct it in line with the punches and cutters, which imme-
diately commence to operate upon it by reason of the lift of the swell or
projection of the cam, which operation terminates at the point marked Y, (the
burnishers meanwhile being held out of action by the cam P.) The said
punches and cutters are then withdrawn by the action of the spiral springs M',
and immediately the punch blocks are lifted by the cam T, and the burnishers
are liberated from the cam P, and guided into position by the cam Q, and
pressed into action by the springs N³, which continues during the remainder
of the revolution of the table, or to the termination of the cam at Z, where
the burnishers are withdrawn, and the healds being at liberty are immediately
seized hold of by the discs or rotating nippers W, which throw them out from
the machine in a finished state in the direction of the dotted line X.
It will now be seen that means of this Invention the healds, herein-
before referred to, can be produced at a very rapid rate, the material being
fed in continuously, when at every revolution of the table eight healds are
produced (or more, if arranged for, may be produced), and the action of all
the working parts being so uniform, steady, and certain that the machine may
be driven at a good speed. It will also be evident that this machine may be
adapted for punching, shearing, or cutting and burnishing other articles of
manufacture of a similar kind. And also it will be observed that other forms
of holes than round ones may be punched, and in such case the burnishers
being of corresponding form instead of having rotary motion given them may
have a reciprocating motion imparted by the cam Q, being made of an undu-
lating form, and the rollers or pinions N¹ being removed from contact with
the flange O. Also the shearing or cutting may be of different forms,
according to the formation of the cutters or cutting instruments which may
be employed.
Having thus fully described the nature of this our said Invention, and the
manner in which the same is and may be performed or carried into practical
operation, we would have it distinctly understood that we do not confine or
restrict ourselves to the precise details of construction or arrangement of
the parts of this inachine or the particular application thereof, which we
have herein referred to; but what we claim as of our Invention, is,-
Firstly, the combining, arranging, and applying mechanism for punching,
shearing, or cutting and burnishing metallic healds or similar articles at one
operation.
Secondly, the construction, adaptation, and application of machinery of

page_text: continuous rotary action, in manner and for purposes substantially as herein
lescribed and illustrated by the accompanying Sheet of Drawings.
In witness whereof, I, the said John Craven, for and on behalf of myself
and the said Samson Fox, have hereunto set my hand and seal, this
Twentieth day of April, One thousand eight hundred and sixty-four.
