PROVISIONAL SPECIFICATION.
An Improved Apparatus for Dividing and Cutting Metal Plates and
Sheets.
We THOMAS PANARIO of 48 Octavia Street Battersea in the County of Surrey
Clerk and FRANK RICHARD of 27 Abbeyfield Road Rotherhithe in the County of
Surrey aforesaid Engineer do hereby declare the nature of this invention to be as
follows:-
The object of our invention is to provide a simple cheap and very efficient
apparatus for dividing and cutting metal plates and sheets into corresponding
and similar or other forms or blanks ready for their further treatment as may
be desired.
To carry out this object we construct a table of the desired length and breadth
for the metal plate or sheet and at or near one end of this table we transversely
crect a guide post or frame which may extend entirely across the table and in or
on both faces of this guide post or frame are fitted sliding blocks whereto a vertical
reciprocating motion can be preferably separately given by and through and from.
eccentrics or cams or cranks or other appliances mounted on a shaft overhead or
otherwise in any usual or convenient manner and the sliding block that is the
nearer to the end of the table carries a knife while the other sliding block carries a
number of punches or other similar appliances formed and arranged in the following
We will now describe this apparatus as fitted to divide and cut the metal
plate or sheet into cubes or square forins or blanks. In this case the punches are
made oblong their shortest sides being transverse to the table and they are so fitted
and arranged and fixed in the sliding block that there is a space between each two
adjacent punches equal to their shortest sides. Any suitable feed can be used in
and with this apparatus that will provide the required intermittent feeding motion
and we preferably use two horizontal rolls on one of which is a ratchet wheel into
the teeth whereof one or more pawls engage which pawls can be actuated by the
sliding block through tappets or studs or otherwise.
manner.
The action of this apparatus is as follows. The blocks are caused to slide up
and down and by the feed the leading edge of the plate or sheet is brought under
the punches which proceed to punch or divide the required cubes or squares there-
out which then fall through an aperture in the table into a receptacle below but as
these punches are oblong they project somewhat beyond the leading edge of the
plate when they come down thereupon whereby there is no danger that an hole
shall be punched in the plate but rather that the required cube or square shall be
formed on the one side by the leading edge of the plate and on the other three
sides by the dividing of the plate by the three edges of the punch. As the plate is
again fed under the punches they again come down thereupon and the aforesaid
action is repeated and so on. As is aforesaid there is a space between each two
adjacent punches equal to their shortest sides that is equal to the sides of the cubes
or squares that are being punched out of the plate and therefore the consequence of
this repeated punching is that the plate is being divided longitudinally the alternate
strips thereof that are not touched by the punches passing on between the same
until they are brought under the knife which comes down thereupon and cuts off
the end of each strip a corresponding and similar cube or square which then falls
through another aperture in the table into the same or another receptacle below
and thus when the speed of the knife and the punches and the feed are all properly
adjusted the plate is divided and cut into the desired cubes or square forms or blanks
which are ready for their further treatment.
It is obvious that other shaped forms or blanks can be produced in a similar

page_text: manner the punches being constructed of the shapes required and the knife being
arranged and fitted and if necessary formed and duplicated or otherwise treated as
may be needed and the feed being also arranged and fitted to feed the plate in
under the dividing and cutting appliances in the desired manner.

COME LATE SEEGIFICATION,
An Improved Apparatus for Dividing and Cutting Metal Plates and
Sheets.
We THOMAS PANARIO of 48 Octavia Street Battersea in the County of Surrey
Clerk and FRANK RICHARD of 27 Abbeyfield Road Rotherhithe in the County of
Surrey aforesaid Engineer do hereby declare the nature of this invention and
in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
The object of this our invention is to provide a very simple and cheap and yet
extremely efficient and effective apparatus for dividing and cutting metal plates
and sheets into corresponding and similar or other forms or blanks ready for their
further treatment by and in and through any means and appliances for and because
of any purpose or end as may be desired.
In order the more clearly to explain this our invention and in what manner the
same is to be performed we refer to the accompanying drawing wherein we have
shewn our apparatus as constructed and fitted and arranged for dividing and
cutting the metal plates and sheets into cubes or square forms or blanks and
Figure 1 is a side elevation partly in section of this apparatus Figure 2 is a plan of
the same also partly in section and Figure 3 is a front elevation of the same
likewise partly in section.
We construct a suitable table A of the desired length and breadth having
regard it may be to the dimensions of the metal plate or sheet that is to be treated
thereon and at or near one end of the table A we transversely erect a suitable
standard or frame or guide post B which may extend entirely across the table A
and in or on both faces of this standard B are fitted in any usual or convenient
manner sliding blocks C and D whereto a vertical reciprocating motion can be
given preferably separately in manner as is shewn in the drawing by and through
and from eccentrics E and F mounted on a shaft overhead which can be revolved
through the usual pulley or this vertical reciprocating motion can be given in any
other usual or convenient manner and by and through any ordinary appliances.
The sliding block D that is the nearer to the end of the table A carries in any
usual manner a transverse knife or cutter H while the other sliding block C carries
also in any usual manner a number of punches G arranged transversely across the
table A. The knife or cutter I may be constructed and formed in any ordinary.
or convenient manner and the punches G are made of an oblong form horizontally
in transverse section their smaller sides being transverse to the table A. and they
are so formed and arranged in or fitted or fixed on the sliding block C that there
is a space between each two adjacent punches exactly equal in every direction and
in all dimensions to each punch.
Any suitable feed arrangement can be used in and with this apparatus that will
provide and produce the required intermittent feeding motion and we shew in the
drawing one very convenient and appropriate arrangement which we preferably
use. We mount in or on the table A in the proper position near the standard B
and on that side thereof on which are the punches G two horizontal and transverse
rolls K and L which are so fitted in any usual manner as to be adjustable in respect
of each other whereby the metal plate or sheet can be duly clasped between them
and on the side or end of the upper roll K is fixed a ratchet wheel M into the teeth
whereof a pawl-N can engage which-pawl N is carried on and by a loose-disc-P

page_text: may
mounted on the shaft of the roller K and in this disc P are formed jaws or it
be is formed a recess whereinto a roller or stud R' mounted on or secured to the
sliding block C engages. All these parts and appliances are so formed and pro-
portioned and arranged that when and as the sliding block C descends through and
by the roller R in the jaws thereof the disc P and therefore the pawl N are caused
to move backwards by the space of one tooth of the ratchet wheel M whereby the
pawl N engages a fresh tooth thereof and then when and as the sliding block C
ascends in the same manner the disc P and therefore the pawl N are caused to
move forwards by the space of one tooth of the ratchet wheel M whereby the same
is by so much revolved and the roll K is correspondingly revolved feeding the metal
plate or sheet correspondingly forwards towards the punches G and the teeth of
the ratchet wheel M are so formed and proportioned that such feeding forwards of
the metal plate or sheet as is occasioned and caused by the one movement herein-
before described of the roll K is exactly equal to the horizontal transverse dimension
of each of the punches G.
The metal plate or sheet to be treated can very conveniently be in the form of a
long strip or ribbon in which case we should arrange this strip in the form of a
roll S and mount the same in the usual manner as is shown in the drawing on the
table A and we should lead the strip from the roll S under a guiding roll T
mounted in the proper position on the table A to the feeding rolls K and L.
The ordinary apertures V and W must obviously be made through which the
punches Gand the knife H can pass and work and into which what is punched and
cut from the plate or sheet can be thrust and we preferably make these latter
apertures V and W that are formed through the table A tapered or that is to say
they are larger on the under surface of the table than on the upper surface thereof
as is shewn in Figure 1 by which arrangement there will be no danger that the
pieces so punched and cut from the plate or sheet will stick or be jammed in these
apertures. These apertures V and W on the under surface of the table can open
into preferably two shoots or guide troughs X and Z which can be led to one or
more suitable receptacles as may be desired.
The action of this apparatus hereinbefore described is as follows. The blocks C
and D are caused to slide up and down at the desired speed and by the feeding
rollers and L the leading edge of the metal plate or sheet is brought under the
punches G which proceed to punch the required cubes or squares thereout which
then fall through the aperture V and the shoot X if any into a receptacle below
but as these punches Garc oblong in horizontal transverse section as is herein-
before stated to enable them to punch out the required cubes or squares the feed
is so arranged that these punches G project somewhat beyond the leading edge of
the plate or sheet when they come down thereupon by which arrangement there is
no danger that holes shall be punched in the plate or sheet but contrariwise it is
ensured that the required exact cubes or squares shall be formed on the one side
by the leading edge of the plate or sheet and on the other three sides by the
dividing of the plate or sheet by the three edges of each of the punches G. As is
hereinbefore described when and as the punches with the block C are raised and
by the ascent of the same the plate or sheet is again fed forwards under the
punches G by so much as is exactly equal to the horizontal transverse dimension of
each of the punches G and therefore when these punches G again come down there-
upon exact cubes or squares are again punched thereout and so on. As is herein-
before stated there is a space between each two adjacent punches exactly equal in
every direction and in all dimensions to each punch and therefore necessarily in the
horizontal transverse dimension thereof or that is to say exactly equal to each of
the sides of the cubes or squares that are being as aforesaid punched out of the
plate or sheet and very obviously the consequence of this repeated alternate
punching and feeding hereinbefore described is that the plate or sheet is being
divided longitudinally into strips of equal breadth alternate strips being treated as
aforesaid by the punches while the other alternate strips thereof that are not
treated by the punches pass on between the same until they are brought under the

page_text: knife H which proceeds to cut off the end of cach strip an exactly corresponding
and similar cube or square which then falls through the aperture W and the shoot Z
if any into the same or another receptacle below. Thus and in this manner as
herein before described when the speed of the knife and the punches and the amount
of feed are all properly adjusted the plate or sheet is divided and cut into the
desired cubes or square forms or blanks which are ready for their further
treatment.
We have thus described and we have shewn in the accompanying drawing this
our apparatus as constructed and fitted and arranged for dividing and cutting metal
plates and sheets into cubes or square forms or blanks but it is obvious and we
would have it clearly understood that we do in no wise limit ourselves thereto for
it is evident that forms or blanks of other shapes can easily be produced in a
similar manner in. cach case the punches being constructed of the required shape
or sliapes in horizontal transverse section and otherwise and the knife or cutter
being arranged and fitted and if necessary formed and both appliances or either
of them being duplicated or otherwise treated as may be needed and the feed
also being arranged and fitted to feed the plate forwards in the desired manner
and at the required speed or speeds under the dividing and cutting appliances
and no further description or explanation is or can be needed.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
The arrangement and combination of parts and appliances constituting our
improved apparatus for dividing and cutting metal plates and sheets substantially
as hereinbefore described and set forth.
