PROVISIONAL SPECIFICATION left by the said John Cameron Mac
Donald and Joseph Calverley at the Office of the Commissioners of
Patents, with their Petition, on the 6th December 1866.
We, JOHN CAMERON MAC DONALD, of Waddon, near Croydon, in the
County of Surrey, and JOSEPH CALVERLEY, of the Albany Road, Camberwell,
in the same County, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN MACHINERY FOR PRINTING AND CUTTING INTO SHEETS ROLLS
OF PAPER, AND FOR COLLECTING SHEETS 80 CUT, ALSO IN THE MANUFACTURE OF
STEREOTYPE PRINTING SURFACES," to be as follows:-
+
In the manufacture of cylindrical stereotype surfaces we employ a matrix of
papier maché moulded by pressure to the surface of type, as is now commonly.

page_text: the case; the matrix is placed around the inner circumference of a cylindrical
mould, and is held by bevelled recesses in the top or cover of the cylinder, the
cover of the cylinder being moveable and formed for convenience in three
segments of a circle. Around the top of the cylinder or around the cover an
air chamber is formed, into which when melted metal is poured into the
mould the air at the back of the matrix is forced, and escape passages are
formed to allow the air to pass away; by this means the matrix will be caused
to fit accurately against the inner circumference of the mould and a perfectly
cylindrical casting will be obtained. The central part of the mould is filled
up with a metal core slightly tapering from the top to the bottom, and after
the casting is made the core is raised by means of the ram of an hydraulic
press beneath it.
The core has vertical grooves formed in it from top to
bottom, so that the back of the stereotype plates may be formed with corre-
sponding ribs which will admit of being readily cut away in order that the
plate may be reduced to an uniform thickness, and consequently give au
uniform impression in printing. The metal is poured into the mould from
the top on two opposite sides, and for this purpose we employ ladles with
their delivery sides or spouts curved to correspond with the circumference of
the top of the mould, so that they may rest thereon and pour into the mould
a broad uniform stream of metal. After the casting is removed from the
mould it is placed on the conical mandril of a lathe, in order that its edges and
head may be cut off, and also that the casting may afterwards if desired.be
divided longitudinally into two parts. The rests which carry the cutters or
tools slide on a suitable bed at the side of the mandril.
In order to cut down the ribs at the back of the plates each plate is placed
in a semicircular bed, and while so held is acted on by a rotating cutter
composed of three or other number of blades, so formed and fixed around an
axis that the stereotype plates may be reduced to the desired cone (to fit the
rollers of the printing machine) at one revolution of the cutter.
In order to form the rolls of paper used in printing machines that print on
continuous lengths we wind the paper on to rollers divided longitudinally into
two wedge-shaped pieces, so that after the paper has been wound as tight as
may be thereon the roller may readily be withdrawn, the roller is made of
small diameter in order to leave but a small hole through the roll of paper,
and thus the roll may be made sufficiently strong to preserve its form during
its transit from place to place. In the printing machine the roll of paper is
held between two cones sliding endwise on a rod, the cones being pressed
inwards into either end of the central hole by means of nuts working on screw
threads cut on the rod on one end of the rod is a pulley having a friction

page_text: strap around it, by which the requisite tension may be placed on the paper,
thus obviating all tendency to overrun when a stoppage takes place and to
crease.
:
In order to damp the paper before it arrives at the printing cylinders
it is passed over three rollers arranged in a triangle, thus:, and enclosed
within a steam chest; by this means increased facilities are obtained forgiving
tension, and a larger surface of the paper is exposed to the action of the steam
than if the paper were led in a direct line through the steam chest.
}
After the paper has been printed by the printing cylinders it passes to a
cutting apparatus to be cut into lengths; the cutting apparatus consists of two
cylinders dished out so as to be in contact only on what are margin spaces
when the machine is printing; one cylinder around which the paper is curved
has a longitudinal slot formed in it, and the other cylinder is provided with a
steel knife entering into the slot as the cylinders rotate; this knife has an
angular or undulating toothed edge sharpened from both sides, and on each
side of the knife are arranged spring plates which hold the paper firmly
against the other roller, both in front and rear of the knife at the moment the
cutting takes place. Small recesses are formed in the knife at either end, in:
order that the paper may not be completely severed, but so as to leave small con-
necting strips undivided to ensure the regular passage of the succeeding sheets
into the delivering tapes; the delivering tapes are driven by rollers travelling
slightly faster than the printing cylinders, and are so arranged that the upper
and under tapes only begin to nip each sheet after the cutting process is
complete. As soon as a cheet is thus taken hold of by the tapes it is torn.
away from the succeeding sheet and is carried forward at the quicker speed of.
the tapes; there will thus be a space formed between the succeeding sheets.
as they pass from the delivery tapes. The delivery tapes deliver the sheets
between other travelling tapes carried by a swing frame, which is caused to..
swing to and fro on a horizontal axis at its upper end; the sheets pass away
from the bottom of the frame, and are alternately delivered on either side of
two sets of vertical tapes, the upper rollers of which are close together, and are
immediately below the swing frame; these tapes are driven at a still further:
increased speed; the two lower rollers of the two sets of tapes are placed at
a distance apart from one another, whilst the upper rollers are as above
mentioned close together. The sheets of paper as they descend from the swing
frame will therefor, to some extent, rest on the travelling tapes whilst they are
drawn downwards by them; as each sheet is thus being drawn downwards
lance wood fingers rocked on a shaft below are caused to pass to and fro.
between the rows of tapes and strike the sheet so as to free it from the tapes,.

page_text: and at the same time to arrest its speed by an overlap of the upper portion on
the tops of the fingers; the sheet then falls on to a bar or roller in such
manner as to rest and balance upon it; the lancewood fingers of the rocker
pass alternately between the two sets of tapes, and will thus after depositing
one sheet on to a roller in front of one set of tapes deposit the next sheet on
to another roller in front of the other set of tapes, and so on continuously.
The rollers may be so mounted as to be capable of being shifted a distance
endwise after a given number of sheets has been deposited on them, so that
the number of sheets may readily be counted.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Cameron Mac Donald and Joseph Calverley in the
Great Seal Patent Office on the 6th June 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHN,
CAMERON MAC DONALD, of Waddon, near Croydon, in the County of Surrey,
and JOSEPH CALVERLEY, of the Albany Road, Camberwell, in the same County,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixth day of December, in the year of our
Lord One thousand eight hundred and sixty-six, in the thirtieth year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto us, the said John Cameron Mac Donald and Joseph Calverley, Her
special licence that we, the said John Cameron Mac Donald and Joseph
Calverley, our executors, administrators, and assigns, or such others as we,
the said John Cameron Mac Donald and Joseph Calverley, 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 FOR PRINTING AND CUTTING
INTO SHEETS ROLLS OF PAPEE, AND FOR COLLECTING SHEETS 80 CUT, ALSO IN
THE MANUFACTURE OF STEREOTYPE PRINTING SURFACES," upon the condition
(amongst others) that we, the said John Cameron Mac Donald and Joseph
Calverley, our executors or administrators, by an instrument in writing under
our or their hands and seals, or under the hand and seal of our of us or them,
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

page_text: 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 John Cameron MacDonald and
Joseph Calverley, do hereby declare the nature of the said Invention, and.
in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement thereof, that is to say :-
. In the manufacture of cylindrical stereotype surfaces we employ a matrix
of papier maché moulded by pressure to the surface of type, as is now com-
monly the case. The matrix is placed around the inner circumference of a
cylindrical mould, and is held by bevilled recesses in the top or cover of the
cylinder,the cover of the cylinder being moveable and formed for convenience
in three segments of a circle. Around the top of the cylinder or around the
cover an air chamber is formed, into which, when melted metal is poured into
the mould, the air at the back of the matrix is forced, and escape passages
are formed to allow the air to pass away; by this means the matrix will be
caused to fit accurately against the inner circumference of the mould, and a
perfectly cylindrical casting will be obtained. The central part of the mould
is filled up with a metal core slightly tapering from the top to the bottom, and.
after the casting is made the core is raised by means of the ram of a hydraulic
press beneath it. The core has vertical grooves formed in it from top to
bottom, so that the back of the stereotype plates may be formed with corre-
sponding ribs which will admit of being readily cut away in order that the
plate may be reduced to an uniform thickness, and consequently give an
uniform impression in printing.
On Sheet 1 of the Drawings hereunto annexed are shown views of a
mould suitable for casting cylindrical stereotype surfaces in the manner above
described...
Figure 1 shows a vertical section of the mould, and Figure 2 a plan view
of the same, the cover being removed; Figures 3 and 4 show separately
similar views of the core which is to fill up the central portion of the mould.
In these views a is the cylindrical mould; b, the central core which, as
above described, has longitudinal grooves formed in it to produce longitudinal
ribs on the back of the casting; these grooves are made to taper from one
end of the cylinder to the other, they being broader at the bottom than at'
the top of the cylinder so as to facilitate the withdrawal of the core from
the casting. c is the cover which is by preference made in three parts or
segments; a plan view of one of these segments is shown at Figure 5.
When casting stereotype plates to be used for printing newspapers we
prefer to divide the mould vertically into two compartments or parts, each

page_text: suitable for producing a plate for printing one page of the paper; the divisions
we form by two vertical feathers a projecting from opposite sides of the
interior surface of the cylinder a, as shown in the plan view of the mould
(Figure 2); slots are formed in the central core into which the feathers
enter, and they fit therein sufficiently to prevent metal when poured into one
compartment of the mould from passing into the other compartment; one
page may thus be cast without at the same time casting the other page with it.
In preparing the mould for casting the papier maché matrix is first placed
into one compartment of the mould a, its lower edge being inserted between
its inner circumference and the half ring d at its bottom; the top edge of the
matrix is then pressed or sprung in under the bevilled recess c¹ in the cover c.
Another matrix may similarly be placed in the other compartment of the
mould. The core bis afterwards lowered into the mould, and as the coro b
arrives at its lowest position a bevilled edge 62 at its lower end comes against
the half rings d which are similarly bevilled; the half rings a will thus be
pressed outwards, and the lower edge of the matrix will be uipped firmly
between the ring and the interior of the cylinder a; this will prevent any metal
passing up behind the matrix. When the matrix has thus been fixed into one
or both halves or compartments of the mould the metal is poured in, and we,
by preference, employ for this purpose ladles (such as shown at Figure 6)
having their delivery sides or spouts curved to correspond with the circum-
ference of the top of the mould, so that they may rest thereon and pour into
the mould a broad uniform stream of metal. The air at the back of the
matrix is allowed to escape into an air chamber eformed around the junction
between the top of the cylindrical mould and its cover, and from this chamber
the air passes away through escape passages e', shown in the plan view,
Figure 2. When the casting is complete the core is raised out of the mould,
by preference by the ram of an hydraulic press beneath it; afterwards the
cover c, which before was held in its place by three bolts passing through three
holes a³ in the flanges of the cylinder and of the cover is removed, and the
casting or castings are taken out.
In place of the cylindrical stereotype plate being cast in two halves, as above
described,a complete cylinder might be cast and afterwards divided into two
halves ; we however prefer to cast each page separately, as above described.
After the casting is removed from the mould it is placed on to the mandril a of
the machine, shown at Figures 7 and 8, to have the heads of the plate cut off
and to bring it to the required gauge; each semi-cylindrical casting is for
this purpose placed on the mandril, and is held down to it by clips acted on
by a bolt passing through the mandril; the mandril is then rotated, and the

page_text: cutting tools b, b, which have previously been. set to the required guage, are
fed forward so as to cut off the ends of the casting; the casting is afterwards
removed, and is placed in the semicircular sliding bed a of the machine,shown
at Figures 9, 10, and 11 (paper or other material being placed between the >
bed and the plate so as not to injure its surface). A plate a! is screwed on
to the edge of the bed a at one of its sides, so as to prevent the casting from
turning whilst being acted on by the cutter 6 which is to cut down the ribs on
the back of the plate to bring the back of the plate to the same taper or form:
as the taper or form of the cylinders of the printing machine upon which the
plates are to be fixed; afterwards the bed carrying the plate is fed up to the
cutter 6 by turning the hand wheel c' on the axis of the screw c, and during.
this time the cutter has rotatory motion imparted to it from an axis d,this axis
being turned either by a driving band on the fast pulley d' or by the hand
wheel dupon it. The cutter is formed of three blades fixed spirally around
an axis, and the cutting edge of each blade is further from the axis at one of
its ends than at the other, so that when the semicircular casting fixed in the
sliding bed a is brought under the cutter the ribs on the casting will be
reduced to the form required for fitting upon the cylinder of the printing.
machine, the cylinder of the printing machine upon which the stereotype plates
are to be fixed being by preference made of a slightly conical form.
What we claim, as respects this part of our Invention is, first, the forming
a mould for casting cylindrical stereotype surfaces in the manner herein
described, that is to say, with an air chamber e and escape passages around
the mould to allow the air to escape from the back of the niatrix, whilst.
the upper edge of the matrix is held in a recess in the cover, as herein -
described.
Secondly, the forming longitudinal grooves in the core of the mould so as
to produce longitudinal ribs at the back of the stereotype plates.
Thirdly, the reducing the ribs at the back of the castings by placing them
in a semicircular bed which carries them beneath a rotating cutter, the cutting
edges of which are made of the same contour or form as the cylinder of the
printing machine upon which such plates or castings are to be fixed.
At Figures 12, 13, and 14 are shown views of a machine for printing and.
cutting into sheets rolls of paper, and for.collecting the sheets so cut; these
views show clearly our various improvements in this class of machinery.
Figure 12 on Sheets 4 and 5 is a side view of the machine; Figure 13 on
Sheets 6 and 7 is a longitudinal section; and Figure 14 on Sheet 8 is an end.
view of the machine; this latter view shows clearly the arrangement of the:
machinery for collecting or delivering the sheets of paper after they have been.

page_text: printed and cut off from the continuous length of paper that is fed into the
machine.
In order to form the rolls of paper used in printing machines that print on
continuous lengths it is necessary that such rolls should be wound sufficiently
hard to prevent their being injured when being transported from place to
place, and to effect this we wind the paper on to rollers divided longitudinally
into two wedge-shaped pieces, so that after the paper has been wound as tight
as may be thereon the roller may by circular or other nuts acting on each
end readily be withdrawn. The roller is made of small diameter in order to
leave but a small hole through the roll of paper, and thus the roll may be
made sufficiently strong to preserve its form. The roll of paper is in the
printing machine held between two cones a, a, sliding endwise on a rod or
axis 6 supported at its two ends in bearings c, shown at Figures 12 and 13,
the cones being pressed inwards into either end of the central hole of the roll
of paper by means of nuts working on screw threads cut on the rod, as is
shown clearly in the view of one end of this rod, represented at Figures 15,
Sheet 2. The holding the roll of paper between cones in this manner fixes
the roll of paper to the axis, and in addition keeps the roll of paper from
swerving to one side or the other, and thus an accurate register of the side
margins is maintained. On one end of the rod b is a pulley d having a friction
strap around it by which the requisite tension may be placed on the paper,
thus obviating all tendency to overrun (when a stoppage takes place) and to
crease; the placing tension on the axis carrying the roll of paper also keeps
the paper stretched out evenly as it is passing through the machine, and this
ensures the roll of paper being cut into sheets by the cutting apparatus in what
are margin spaces on the paper, whereas if the paper were allowed to be slack
as it is passed through the machine the cutting would be irregular,and would
not cut through the centre of the margin space as it should do. In order to
damp the paper before it arrives at the printing cylinders it is passed over
three rollers e, e, e, arranged in a triangle, thus :, and enclosed within a steam
chest; by this means increased facilities for giving tension are obtained, the
paper is also brought into closer contact with the rollers, so that the damping
of the paper is rendered more equal than if the rollers of the damping appa-
ratus were placed in a straight line. Each of the rollers is, by preference,
covered over with blanket or other fibrous material, and the steam chest is
covered over with a lid f' lined with blanket. The paper is led in at one side
of the chest between the chest and its lid, and after being led around the
rollers e,as indicated in the sectional view, Figure 13,is led out at the opposite
side of the case; steam is supplied to the chest through the perforated pipe g

page_text: which passes through the case from one end of it to the other, and around this
pipe is lapped cotton, wool, or other fibrous fabric or material. The paper
after being passed through the steam chest is led between the rollers h, h,
between which the paper is nipped; these rollers are by gearing caused to
travel at the same surface speed as the printing cylinders, and they draw the
paper through the steam chest, so that there will be no drag upon the paper
as it passes over the printing cylinders. The two cylinders i, i, which carry
the stereotype plates are placed one above and the other below two pressing
rollers i, i, covered with blanket or other soft material.
A side and end view of one of the cylinders i isshown at Figures 16 and 16*,
Sheet 3. The cylinder is formed to taper from its centre towards both of its
ends so as to receive end to end two cylindrical stereotype plates made as
above described, and as each half of each cylindrical plate is suitable for:
printing one page there will be four pages printed on one side of the paper
for each revolution of a printing cylinder. The side edges of each plate are,
as will be seen, held in dovetail recesses 2, the dovetail'recess for holding one;
side of the plate being formed in a projection 3 at the centre of the cylinderi,
and the dovetail recess for holding the other side of the plate being formed in
a noveable end plate or collar 4; fixed stops are also attached to the cylinder,
against which one of the ends of the plates are placed, and the plates are
thus held firmly on the cylinder and prevented from moving. The paper
after passing between the rollers h is led over the upper pressing roller &¹, and
is by it pressed against the upper printing roller i; the paper is afterwards
led down and passed between the two pressing rollers, and is then passed
between the lower pressing roller and the lower printing roller. The upper
and lower printing rollers are supplied with ink by inking rollers *; the
manner in which these rollers are supplied with iuk is not shown in the
As there will be
Drawing, as it may be effected in any ordinary manner.
what is called a "set off" on the blanket of the lower pressing roller by
reason of the surface of the paper which has just been printed on being
pressed against it, we by preference employ an endless cleaning blanketj to
keep this roller clean; this endless blanket is distended between two rollers
, and is by one of these rollers kept in contact with the lower pressing roller.
Should this cleaning blanket itself become too dirty its surface can readily be
wiped without stopping the machine. After the paper has thus been printed
on both sides by the printing cylinders it passes to a cutting apparatus to be
cut into lengths; the cutting apparatus is clearlyshown in the sectional view
Figure 13, and consists of two cylinders & dished out in the centre so as to be
in contact only on what are margin spaces; one cylinder (the upper one)

page_text: around which the paper is curved has a longitudinal slot k¹ formed in it, and
the other cylinder has fixed to it a steel knife ³ entering into the slot as the
cylinders rotate; this knife has an edge composed of long angular projections,
the edges of each projection being sharpened from both sides, and on each
side of the knife are arranged spring plates which are to hold the paper
firmly against the upper roller both in front and rear of the knife at the
moment the cutting takes place. The spring plates 3 on either side of the
knife are capable of moving to or from the centre of the roller k that carries
them and are constantly pressed outwards by spiral springs contained in tubes
carried on the interior of the roller, their movement being limited by suitable
stops. As the knife is by revolution of the rollers brought round to the
point where the rollers meet together the plates are pressed inwards whilst
the knife enters the groove of the upper roller, and thus the paper is divided at
the same time that the cut edge of the paper on either side of the knife is
held firmly between the pressing plates and the upper roller. Small recesses
are formed in the knife at either end in order that the paper may. not be
completely severed, but so as to leave small connecting strips undivided, to
ensure the regular passage of the succeeding sheets into the delivery tapes.
As the paper passes from between the cylinders k of the cutting apparatus it
is carried onwards between two sets of endless tapes 1, 1, which are caused to
travel at a greater surface speed than the cylinders; the endless tapes of
the lower set pass around a small roller m placed close up to the cylinders,
while the endless tapes of the upper set pass around a small rollern, which
is placed a short distance above the roller m. As the tapes pass from these
rollers the tapes of both sets are led between two rollers o, o, the tapes thus
converge from the rollers m and n towards the rollers o; the rollers o are
placed at a somewhat greater distance from the cylinders k than the length of
the sheets of paper which are cut off by the cutting apparatus, so that although
the sheet of paper is carried along between the tapes, yet the tapes do not
take sufficient hold of the sheet to tear it off until its forward end has been
carried nearly up to the rollers o. The two outer tapes of the upper set, and
also the central tape of this set which comes over a margin space on the paper,
are pressed downwards and brought into contact with the corresponding tapes
of the lower set by means of rollers o¹, so that the side edges and centre of the
sheets of paper are held between and guided by these tapes. When the
forward edge of a sheet of paper has by the tapes been brought nearly up to
the rollers o the cutting apparatus will have partially or almost entirely cut off
the sheet from the continuous length of paper in the machine; the tapes of the
upper and lower setwill then as they converge together to pass between these

page_text: rollers take sufficient hold of the sheet of paper to complete the severance;
the sheet will then be carried forward at the quicker speed of the tapes, and
thus a space will be formed between the succeeding sheets. The tapes of the
upper and lower set after passing between the rollers o are both led over a
roller p, and are then led respectively over rollers rand r¹, carried at a short
distance apart from one another at the bottom of a pendulous frame o, which
is capable of swinging freely on the axis of the rollerp; the tapes of the upper
set are passed over a small guide roller before being passed over the rollerr,
so as to keep the two sets of tapes in contact with one another until they
arrive nearly up to the rollers and r; the tapes after passing over these
rollers are led back over guide rollers to the rollers nandm. Immediately below
the bottom of the swing frame are two sets of endless tapes, t, t, which are
each supported between rollerst¹,t'; the two upper rollers t'are close together,
whilst the two lower rollers are at a short distance apart from one another.
The pendulous frame has an oscillatory motion imparted to it by eccentrics u¹
on the axis u, so as to bring the rollers and r¹ at the lower end of the frame
first to one side and then to the other of the upper rollerst', and this swinging
motion is so timed as to cause the frame first to deliver the end of one sheet
on to the inclined travelling surface presented by one set of the tapest, and
whilst this sheet is being carried downwards on the tapes the pendulous frame
swings over to the opposite side of the rollers t¹, so as to be ready to
present the end of the succeeding sheet to the inclined travelling surface
formed by the other set of tapes. Between the axes of the lower rollers t' is
an axis, carrying a number of light fingers », formed by preference of thin
strips of lancewood set edgewise on the shaft as shewn. On the axis v
are also lever arms v2, which by connecting rods are connected with straps
working on eccentrics u² on the axis u, and thus an oscillatory motion is
imparted to the axis v, and the fingers upon it are so caused to beat to and fro
between the tapes of both sets of tapes t, and at each beat in either direction
the fingers as they pass between the tapes strike off the sheet of paper that
was being carried downwards by them, the downward motion of the sheets
being at the same time arrested by fixed stops w. As the fingers throw the
sheets off from the tapes they deliver them on to tables x, x, (one such
table being placed in front of each set of tapes). The sheets accumulate in
flat piles on these tables, the piling if necessary being assisted by a boy seated
at the back of each table; or in place of employing tables for receiving the
sheets the vibrating fingers may be caused to deliver the sheets on to bars or
rollers, but we prefer to collect the sheets on tables as above described. . The

page_text: arrangement of the framing for carrying the axes of the several rollers of the
machine is clearly shown by the Drawings, and the Drawings also show
the manner of giving continuous motion to these axes from the main axis y;
this axis itself receives motion by a toothed wheel upon it gearing with a
toothed wheel on a short axis z, which is driven by a strap working with
a fast and loose pulley. The toothed wheel on the driving shaft transmits
motion by a train of wheels to the printing and inking rollers as is
clearly seen in the side view of the machine shown at Figure 12 (Sheet 4).
The toothed wheel on the driving shaft also by another train of wheels
gives not on to the cylinders k, to the axis u, and also to the axes of
the rollers which give motion to the endless tapes; the way in which motion
is transmitted to the axis u is clearly seen in the sectional view of the
machine Figure 18 (Sheet 7). The axis u has upon it a bevilled toothed
wheel gearing with a wheel on the upper end of an inclined shaft 1, driven at
its lower end by bevil gear from an axis 2, which receives motion from the
axis of the lower cylinder k. The axis of the lower roller of the pair of
rollers o is driven by bevil gear from a short shaft 3, which is itself driven by
bevil gear from an inclined shaft 4, gearing by bevil gear with the axis 2; the
two rollers o are at their opposite ends geared together by toothed wheels;
the roller p is driven at one end by an inclined shaft 5, which is itself driven
from the axis of the lower roller o. At the opposite end of the axis of the
roller p are two bevil wheels; one of these gives motion to a shaft 6 carried
by the pendulous frame, and this shaft by bevil wheels gives motion to one
end of the roller rat the lower end of the frame, the roller r at its opposite
end is geared with the roller 1, as shown in the end view of the machine;
the other bevil wheel at the end of the axis of the roller p gives motion to a
shaft 7,and by this shaft transmits motion to the axis of one of the two upper
rollers carrying the tapes t, and the axis of this roller is geared with the
axis of the other roller t¹ by toothed wheels 8, as shown in the end view.
What we claim in regard to this part of our Invention is,-
First. The fixing the roll of paper to be printed upon an axis by means of
cones sliding on the axis, being forced into the ends of the roll of
paper by
nuts, and the applying tension to the paper as it passes through the machine
by a friction break acting on the axis to which the roll of paper is fixed.
Secondly. The so arranging the rollers of the damping apparatus that the
paper has to be passed over the rollers in a curved course, by which arrange-
ment the paper is broughtinto close contact with all the rollers of the damping
apparatus,and increased facilities for putting tension on the paperareobtained,

page_text: Thirdly. As regards the cutting apparatus for cutting the continuous sheet
paper into lengths we claim the employing spring plates (*) in com-
bination with a knife as herein described.
of
Fourthly. We claim the combined arrangement of apparatusherein described
for collecting the sheets of paper, consisting of two sets of endless tapes which
carry the sheets between them to a swing frame, which delivers them alter-
nately on to two other sets of tapes, from which they are thrown off by
vibrating fingers working between the tapes as herein described.
In witness whereof, we, the said John Cameron Mac Donald and Joseph
Calverley, have hereunto set our hands and seals, this Sixth day of
June, in the year of our Lord One thousand eight hundred and sixty-
seven
