on the 30th September 1873.
I, HENRY EDWARD NEWTON, of the Office for Patents, 66, Chancery.
Lane, in the County of Middlesex, Civil Engineer, do hereby declare
the nature of the said Invention for "IMPROVED MACHINERY FOR FOLDING, OR
PLEATING PAPER," to be as follows:-
The object of this Invention is to construct a machine for folding or
pleating paper automatically, and which is adapted more especially to
the folding or pleating of papers commonly known as ribbed filter
papers.

The machine is arranged so as to operato simultaneously on two sheets
of paper, which are first folded in halves by the action of folding blades
working horizontally, and are then presented to the action of pleating
knives, whereby they have given to them a series of pleats, ridges, crimps,
ribs, or folds, so that they may assume when in use a ribbed conical
form. The pleated sheets are then delivered into a conduit or hopper,
from which they may be withdrawn as required and made into packets
ready for the market.
The machine consists of two vertical spouts or hoppers mounted on
the table of the machine, into which the sheet of paper to be folded
and pleated are successively introduced.
The sheets of paper, after finding their proper level in the hoppers,
are folded in half by means of a pair of folding blades having a
horizontal reciprocating motion, and which work through slots in the
vertical spouts or hoppers.
The folding blades receive motion through rock levers from vertical
rock axles. The blades strike the papers along their contral line and
carry them forward to the centre of the table, where they are subjected
to the action of the pleating knives. These knives are arranged to act
in pairs on opposite sides of the machine, and are secured to holders
carried by a pair of rocking frames having crossed arms, and which rock
on a vertical, central, and fixed axis below the table of the machine..
These frames are capable of receiving a horizontal and a vertical motion
independently of cach other, the horizontal motion of the frames will
give a vibrating or scissors-like action to the pleating knives, while the
vertical motion of the frames will allow of the folding blades being
alternately superposed.
The amount of axial motion given to the crossed frames is sufficient to
allow the pleating knives to overlap the proper distances to form the
pleats or folds in a regular manner. The papers as they are pleated area
received into a spout or hopper, from which they can be withdrawn as
required.
:
Motion is given to the folding blades for folding the papers in half by
means of a train of spur gear driving cams which operate, (1st.,) a sliding
clutch for coupling together the parts of one of the vertical rocking s

page_text: axles, and (2nd.,) an arrangement of levers whereby simultaneous motion
is given to the rock levers which actuate the folding blades.
The rocking frames which carry the pleating knives receive their
motion from levers and connecting rods actuated by cams mounted on
the main shaft of the machine.
SPECIFICATION in pursuance of the conditions of the Letters Patent;
filed by the said Henry Edward Newton in the- Great Seal
Patent Office on the 30th March 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her.
Letters Patent, bearing date the Thirtieth day of September, in the year
of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Henry Edward Newton,
Her special licence that I, the said Henry Edward Newton, my
executors, administrators, and assigns, or such others as I, the said
Henry Edward Newton, my 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 Ohannel Islands,
and Isle of Man, an Invention for “IMPROVED MACHINERY FOR FOLDING OR.
PLEATING PAPER," being a communication to me from abroad by Eugene
Claude, of Paris, in the Republic of France, upon the condition (amongst
others) that I, the said Henry Edward Newton, my executors or admini-.
strators, by an instrument in writing under my, or their, or one of their
hands and scals, should particularly describe and ascertain the nature of.
the said Invention, and, in what manner the same was to be performed,

page_text: calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Henry Edward Newton, 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, reference being had to the Drawing
hereunto annexed, and to the letters and figures marked thereon (that
is to say) :-
The object of this Invention is to construct a machine for folding or
pleating paper automatically, and which is adapted more especially to
the folding or pleating of papers commonly known as ribbed filter
papers.
The machine is arranged so as to operate simultaneously on two sheets
or pieces of paper, which are first folded in halves by the action of
folding blades working horizontally, and are then presented to the action
of pleating knives, whereby they have given to them a series of radially
disposed pleats, ridges, crimps, or folds, so that the paper may assume,
when in use, a pleated conical form. The pieces of paper as they are
pleated are delivered upwards into one of a pair of vertical conduits or
hoppers situate on the table of the machine, and from these hoppers they
may be withdrawn as required and made into packets ready for the
market.
In the accompanying Drawing Fig. 1 is a side elevation of the
machine; Fig: 2 is a plan view seen from above; Fig. 8 is a transverse
vertical section taken in the line 1, 2, of Fig. 2; Fig. 4 is a horizontal
section taken at about the line 3, 4, of Fig. 1; Fig. 5 is a vertical
section on the line 5 and 6, Fig. 6, and shews on a larger scale the folding
blades and the moveable-pleating knives; and Fig. 6 is-a corresponding
plan view.
A is the framing of the machine which supports the table B. Two
vertical spouts or hoppers T, T', are mounted on the table B, and into
these hoppers the pieces of paper to be folded and pleated are successively
introduced. On one side of the frame A is mounted the shaft C, to
which motion may be imparted by hand power, or it may carry a fly.

page_text: wheel with fast and loose pulleys p and p¹ for the purpose of working
by steam power.
The pieces of paper to be folded (by preference of a disc form) are
placed vertically and one at a time in the hoppers T and T¹, where they
fall to their proper level (being guided thereto by stop pins not shown
in the Drawings) preparatory to being folded in half by their respective
folding blades L, L, which have a horizontal reciprocating motion, and
work through slots made in the vertical spouts or hoppers T, T. The
folding blades are kept in position by guides z, 2³, and receive motion
through rock levers 1, 1, from vertical rock shafts, P. The levers 1, P,
are connected to the folding blades L, L³, in any suitable manner. On
the vertical rock shafts 12, 13, are mounted the levers m³, m³, which are
connected by rods m, m², to the double armed lever M, which has for its
fulcrum the central shaft K. By this means it will be seen that on
motion being communicated to either of the rock shafts both folding
blades will be caused to work simultaneously.
The rocking motion is communicated to the rock shafts in the follow-
ing manner:-On the shaft C is fixed a pinion 1, which gears into a
wheel 2 mounted on the stud axle o². Attached to the wheel 2 are the
cams n, n³, and on the hub of this wheel is a pinion 3, which gears into
a spur wheel 4. This wheel 4 is cast with a cam G. On the periphery
of the cam G rolls a small friction wheel g mounted at one end of a rock
lever H, which has its fulcrum at h. The opposite end H¹ of the lever
H is forked, as shewn at Fig. 4, so as to embrace a sleeve s carried by
the boss of a rock lever N', which sleeve is intended to engage at certain
intervals with the clutch s¹ fixed on the shaft . The cams n, n¹, bear
alternately against friction rollers mounted on the forked end of a rock
lever O, which has its fulcrum at O¹. This forked lever O is connected
by an adjustable coupling rod N to a socket piece carried by the lever
N', which is loose on the vertical rock shaft . The gear wheels are so
arranged that while the pinion 1 makes ten revolutions the wheel 2
makes only four, and the wheel 4 only one revolution. By this means
the folding blades L, L', are moved at determinate intervals. The
oscillation of the levers 7, 1, is controlled by the cam G, which rocks the
lever H, and thus puts the clutch s'into gear. When this is effected the
vibrations of the lever N¹ derived from the cams n, n¹, will be transmitted
to the rock shafts P, P, and the folding blades will thereby be caused to

page_text: .
strike the pieces of paper along their central line and carry them forward
to the centre of the table, where they are subjected to the action of
horizontal pleating knives, a¹. These knives are arranged to act in
pairs on opposite sides of the machine, and are secured to holders e, f,
carried by a pair of vertical rocking frames E and F having crossed arms,
and which rock on a vertical, central, and fixed axle K below the table
of the machine. These frames are capable of receiving a horizontal and
a vertical motion independently of each other; the horizontal motion
will give a vibrating or scissors like action to the pleating knives, while
the vertical motion will allow of the pleating knives being alternately
superposed to fold the paper backwards and forwards in radial pleats
under the hopper Y, a pressing block Y₁ working in guides in the hopper
being used to press upon the paper and hold it firmly upon the upper-
most of the reciprocating blades during the pleating operation. The
frames E and F receive their horizontal motion from cams 9, 9', fixed on
the shaft C. These cams act upon stirrups R, R¹, (mounted on the axle
2) and connected respectively by means of rods Q, Q', with the frames
E and F.
The vertical motion is given to the frames so as to bring the pleating.
knives x, x, x¹, ¹, of cach pair alternately into position for making a 2
fresh pleat under that last formed. This motion is effected by means of
the levers i, ", which oscillate on the fulcrums j, j'. These levers i, 2,
bear respectively at one end on the cams I, I', carried by the shaft C,
and at their opposite ends against stud pins u, u¹, fixed in the frames
E, F, and by the rotation of the cams I, I', the frames are moved 2
vertically at the proper moment. The axial motion given to the crossed
frames E, F, is so timed and of such amount as to allow the pleating
knives to advance in turn a sufficient distance to form the pleats or folds
of the required breadth in a regular and even manner until the whole
of the folded piece has been creased into the shape of a closed fan. 3
When this is effected the next succeeding piece brought under the action
of the pleating knives will force upwards the piece completely folded
into the hopper Y or Y', as the case may be, and thus the work will
proceed automatically on the opposite sides of the machine, the paper
being fed by hand to the hoppers T, T¹.

Having now set forth the nature of the said Invention as communi-
cated to me by my foreign correspondent and having explained the

page_text: manner of carrying the same into effect, I wish it to be understood that
under the above in part recited Letters Patent I claim the arrange-
ment of machinery above described for pleating, filtering, and other
papers.
In witness whereof, I, the said Henry Edward Newton, have
hereunto set my hand and seal, the Thirtieth day of March, in
the year of our Lord One thousand cight hundred and seventy-
four.
