Farringdon Road, in the County of Middlesex, for the Invention of "IM-
PROVEMENTS IN PAPER FOLDING MACHINERY." A communication from abroad
by William Braidwood, of Mount Vernon, and Lewis Francis, of the City of
New York, both in the State of New York, United States of America.
PROVISIONAL SPECIFICATION left by the said Edwin Thomas Marler at
the Office of the Commissioners of Patents on the 14th October 1876.
EDWIN THOMAS MARLER, Manager of the Viaduct Works, Farringdon Road, in
the County of Middlesex. "IMPROVEMENTS IN PAPER FOLDING MACHINERY." A
communication.
This Invention relates to the construction of a machine for the folding of paper
in sections of several sheets or in quires for use in paper mills, blank book binderies,
and the like, the object of the Invention being to diminish the cost of folding
blank paper, and performing the work better and with more facility than heretofore.
Blank books folded by this machine will be neater and stronger than other books,
by reason of having the several sheets of the sections forced back closer in the
fold than can be accomplished by hand folding, and consequently the thread will
lie closer in the fold, and hold the leaves of the book more firmly, not allowing the
leaves the end wise motion so destructive to blank books.
To folded paper sold in reams it will give a neater appearance, and the paper
will not be soiled or crumpled as in folding by hand.
In constructing a machine according to this Invention I provide the same with
a frame for supporting the operating parts, and the said machine has a driving
pulley and pinion for driving a gear wheel. There is also a cam shaft to operate
a toggle, and a lever for raising a blade. There is moreover a horizontally moving
pressure jaw, and a toggle to operate the same; also an opposite or stationary
pressure jaw held by set screws, which are used to regulate the distance between
the pressure jaws according to the thickness of the section of paper to be folded.
A back piece is provided for holding one end of the toggle with proper set screws
also used to regulate the distance between the pressure jaws according to the
thickness of the section of paper. Set screws are provided for the pressure jaw and
back piece.

page_text: An open guideway leads down from the feed table to the pressure jaws. The
object of this guideway is to hold in an upright position the two ends of the sheets
to be folded to insure their falling or passing through the pressure jaws after they
have received the pressure to the receiving rollers, to which they are guided by a
drop board.
The feed table is divided into two parts; a side gauge and a double-back gauge
are provided for feeding the paper to; a vertically moving blade is provided to
strike the paper just where it is to be folded, and carry it through the open guide-
way to the pressure jaws to receive the pressure, said blade leaving the paper
immediately before the pressure comes on. Cams are provided to operate the knife,
and levers operated by the said cams are connected to the blade. A roller is
placed in the centre of the toggle, and a cam on the shaft operates the toggle.
Rollers below the pressure jaws are driven by a belt from the cam shaft, and tapes
passing round the rollers carry the paper to the drop box. A set screw is arranged
under the toggle to regulate the distance of the opening of the pressure jaws. The
drop box receives the paper after it has been folded.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Edwin Thomas Marler in the Great Seal Patent Office on the 14th
April 1877.
EDWIN THOMAS MARLER, Manager of the Viaduct Works, Farringdon Road, in
the County of Middlesex. "IMPROVEMENTS IN PAPER FOLDING MACHINERY." A
communication from abroad by William Braidwood, of Mount Vernon, and Lewis
Francis, of the City of New York, both in the State of New York, United States
of America.
This Invention relates to the construction of a machine for the folding of paper
in sections of several sheets or in quires for use in paper mills, blank book binderies,
and the like, the objects of the said Invention being to diminish the cost of folding
blank paper, and to perform the work better and with more facility than heretofore.
Blank books folded by this machine will be neater and stronger than other books,
by reason of having the several sheets of their sections forced back closer in the
fold than can be accomplished by hand folding, and consequently the thread will lie
closer in the fold, and hold the leaves of the book more firmly, not allowing the
leaves the endwise motion so destructive to blank books.
To folded paper sold in reams it will give a neater appearance than that now
sold, and the paper will not be soiled or crumpled as in folding by hand.
In the accompanying Drawing,-
Figure 1 is a side elevation of a machine constructed according to this Invention.
Figure 2 is a vertical section through the centre of the said machine.
Figure 3 is a plan of the said machine with the table removed.
Like letters indicate corresponding parts throughout the Drawing.
A is a frame for supporting the operating parts of the machine, and composed of
suitable side and cross pieces; B is the driving pulley; C is the stud for the
said driving pulley B and pinion D, the latter being provided for driving the
gear wheel F E is a cam shaft for operating the toggle H and the lever S, which
raises the blade Q; G is a horizontally moving pressure jaw. The toggle H operates
this horizontally moving pressure jaw G; 1 is the opposite or stationary pressure
jaw held by set screws K, K, which regulate the distance between the pressure
jaws according to the thickness of the section of paper to be folded. A back piece J
is provided for holding one end of the toggle H by means of set screws L, L, which
also regulate the distance between the pressure jaws, according to the thickness of
the section of paper to be folded; M is an open guideway leading down from the
feed table N, N¹, to the pressure jaws G and I. The object of this guideway is to

page_text: hold in an upright position the two ends of the sheets to be folded to ensure their
falling or passing through the pressure jaws after they have received the pressure
to the receiving rollers W and Y, to which rollers they are guided by a drop board
Z; N, N¹, is the feed table divided into two parts; O is a side gauge, and P is
a movable back gauge for regulating the feed of the paper; Q is a vertically moving
blade arranged to strike the paper on the line where it is to be folded, and carry
it through the open guideway M to the pressure jaws G and I to receive the
pressure, the said blade leaving the paper immediately before the pressure comes
on; R, R, are cams for operating the knife; S, S, are levers operated by the cams
R, R, and connected at one end to the rods T, which rods connect the levers S to
the blade Q; U is a roller in the centre of the toggle H; V is a cam on the
shaft E for operating the toggle H; W, W¹, are rollers below the pressure jaws G
and I, the said rollers being driven by a belt from the cam shaft E; X, X, are
tapes passing round the rollers W and W¹ to carry the paper to a drop box Z2;
Y is a roller revolved by contact with the roller W; Z is a set screw arranged
under the toggle H to regulate the distance the pressure jaws G and I shall open;
Z is the drop board for guiding the paper to the rollers W and Y; Z is the drop
box for receiving the paper after it has been folded.
In the operation of the above-described machine the sheets of paper are fed to
a table to the side and end guides to put the sheet in position. The blade is
brought down upon the said sheet to make the folds by means of the cams R, R,
the levers S, S, and the connecting rods T, and the paper is forced by the blade
through the guideway M to and between the pressure jaws G and I, where it
remains a sufficient time to receive the pressure. The toggle H is then straightened
and the pressure brought to bear on the paper on the edge of the fold.
The toggle is operated by the cam V on the shaft E, and the roller U in the
centre of the toggle. Immediately before the pressure is brought to bear on the
paper the blade is lifted from between the pressure jaws by means of the cams R, R.
The pressure ceases at a certain part of the revolution of the cam V, and the
paper having received the pressure falls down by its own weight to the receiving
rollers W and Y, and is carried by the tapes X, X, to the receiving or drop box Z²
Having thus fully described my said Invention and the manner of performing
the same, I wish it understood that I claim,-
First. The vertically moving blade in combination with the toggle joint, the
horizontally moving pressure jaws, and the slotted guideway, as above set forth
and for the purpose specified.
Second. The delivery or tape rollers in combination with the slotted guideway
and pressure jaws, as above,set forth and for the purpose specified.
Third. A machine for folding paper consisting of the parts constructed and
combined, as shown in the accompanying Drawing, and operating as above set
forth.
In witness whereof, I, the said Edwin Thomas Marler, have hereunto set
my hand and seal, this Fourteenth day of April, in the year of our Lord
One thousand eight hundred and seventy-seven.
