We employ near the entrance of the machine, a paster roller to which motion is
imparted by a cord actuated from any of the moving parts of the machine, so as
not to depend on the traction of the paper passing over it for motion whereby a
more regular or uniform supply of paste is imparted to the edge of the paper which
is thence passed under a pair of adjustable rods or plates to be formed thereon into
a tube, which may be adjusted to the width desired, and in its tubular form passed
through a pair of draw rollers to be severed by a knife or cutter, revolving at
right angles to the machine, A paster roller which is protected by a suitably
formed scraper imparts a supply of paste to a creaser or necker, which immediatly
after descends and transfers the paste to the end of the tube, and laps or turns
over the bottom fold or over lap between a pair of rollers which are held in
contact by a spring or other suitable means to prevent choking. The knife creaser
or necker and last mentioned paster roller are actuated from one shaft, the speed
of which may be readily increased or diminished by change wheels without affect-
ing the draw rollers, to which may be connected by wheels or other suitable means
the knife or creaser Shaft on which is placed the change wheel whereby its speed is

SPECIFICATION in pursuance of the conditions of the Letters Patent filed
by the said Thomas Bibby, James Bibby, John Baron, William Baron, and
Job Duerden in the Great Seal Patent Office on the 24th September 1883.
THOMAS BIBBY JAMES BIBBY and JOHN BARON all of Burnley in the county
of Lancaster and WILLIAM BARON of Rochdale of the said county and JOB
DUERDEN of Burnley aforesaid IMPROVEMENTS IN MACHINERY FOR THE MANU-
FACTURE OF PAPER BAGS.
Our invention relates more particularly to that class of paper bag making
machinery for which Letters Patent was granted to Lewis Henery Spence dated
the first day of July 1861 and numbered 1674. The object of the present
invention is,"
Firstly, to actuate the paster roller from one or other of the moving parts of the
machine, so as not to depend on the drag or traction of the paper passing over it
for motion, whereby a inore regular and uniform supply of paste is imparted to
the edge of the paper, which is also relieved from the strain or pull, that would
otherwise be put upon it, to ensure a proper revolving movement to the paster
roller to the danger of the paper being torn especially in using paper of com-
parative fine texture.
Secondly the application of a pair of adjustable rods whereby templetes of various
sizes may be inserted between them to determine the width of the bag.
Thirdly, the application of a cutter or breaker revolving at right angles or cross
wise of the machine to sever the bag.
Fourthly, to actuate the cutter and creaser from one shaft, the speed of which
may be readily adjusted to regulate and determine the length of the bag, without
affecting the draw rollers.
In Order that our invention may be fully understood and readily carried into
effect, we will proceed to describe the accompanying sheets of drawings reference
being had to the figures and letters marked thereon, the same letters referring to
the same parts in the various views and figures. Fig 1 is a longitudinal
elevation, Fig. 2 a plan, in which are represented our improvements applicable
to machines, or apparatus for the manufacture of paper bags. Fig 3 repre-
sents a ratchet collar, and Fig 4 a section relating to mechanism actuating
'the paster roller hereinafter referred to. Fig 5 is a partial elevation reverse
to Fig 1 in which is seen the mechanism actuating the creaser. Fig 6 represents
Fig 5 in section in which view is seen the movement of the creaser from
the paster roller to the creaser rollers. A A is the framing of the machine at one
end is the continuous roll of paper B as seen in Figs 1 and 2, from which bags are
subsequently made. The roller C is supported in suitable bearings C1 and C2, to the
said roller is fixed the disc D, the periphery of which dips into the paste contained
in the trough D' Previously this roller was dependent on the drag or traction of
the paper passing over it for motion whereby an irregular supply of paste was
distributed to the edge of the paper, which was also subject to considerable strain
or pull, to ensure a proper revolving movement. The object of one portion of our
invention is to remedy this defect by actuating the said roller in an uniform
manner from one or other of the moving parts of the machine, and so arranged
that in the event of the machine being stopped, the paper may be fed into the
machine by hand for the purpose of adjustment, at which time the roller is capable
of being actuated by the paper passing over it, as in the usual manner: The
roller C as seen in Fig 2 is actuated from the lower roller G through the medium
of the cord H, and grooved pulley E this pulley is linked to the roller C by the

page_text: pin E¹ which is freely inserted in the boss of the said pulley seen in section Fig 4
and slightly pressed by the spring E² against the teeth of the ratchet collar Es
which is secured to the roller C, thereby forming an escapement in a forward
direction for the roller C when the paper is drawn by hand. The paper from the
roll B passes over the roller C and disc D. from which paste is distributed along
the edge of the paper which passing forwards and under the guide pulleys F and F¹
is caused to embrace and fold upon the adjustable rods I. I³ and the. templete I³,
by the guiding or folding tendancy of the guide wires or fingers J. J¹, J2 and J³,
the paste previously received cementing the edges of the paper together, The
rods I and I are adjustable so that various sizes of templetes may be inserted and
secured between them. The templete inserted determines the width of the bag.
We will now proceed to describe the mechanism whereby the creaser R and paster
roller S. seen in Figs 5 and 6 are actuated, hereinafter referred to. The creaser R
is connected to the radial arms R¹ and R² in the manner seen in Fig 6 The arm R'
is attached to the rocking shaft X, the arm R² to the stud R³, A vibratory move-
ment is imparted to the shaft X through the medium of the lever X³ arm X' and
crank X³ fix to the axis of the shaft m, as seen in Fig 5 this shaft is driven
from the lower roller n, seen in Fig 2 by the wheels n³, n' and change wheel no
It will be obvious that when the creaser R is in its elevated position seen in Fig 6
it will bear against the paster roller S, by the radial action of the arms R¹ and R³
and receive from the said roller a supply of paste which is afterwards transmitted
to the bottom fold or overlap of the bag. The paster roller S revolves slowly in
the trough S' and is actuated by the pawl or catch S2 attach to the arm S³ secured
to the shaft X A suitably recessed scraper S₁ seen in Fig 2 may be used to remove
superfluous paste. The rollers G, G driven by the wheels G and G2 from the main
shaft O, draws the paper forward from the tube forming devise over the rods I, I¹,
and templete I, this templete rests between the said rollers terminating with a
serrated end a little beyond the serrated end of the plate K and immediately below
it. seen in Figs 2 and 6, against these serrated ends the paper is struck and severed
with each stroke of the cutter or breaker L which revolves at right angles to the
machine. The said cutter or breaker is fixed to the longitudinal shaft L' and is
actuated by the bevel gear L² from the shaft m. The lower roller G actuates the
rollers n, n, through the medium of the wheels n', n³, and n³ these rollers receive
and deliver the detached portion of tube sufficiently over the creaser rollers P, P,
to allow for the bottom folding or overlap of the bag. The creaser R previously
in contact with the paster roller S, as herein before mentioned now descends and
transfers paste to the end of the tube and tucks or doubles over the bottom fold or
overlap between the rollers P, P, these are held in contact by a spring, T, to prevent
choking, and are actuated by the lower rollern, through the medium of the wheels
P¹ and P² so as to deliver the bag now formed that the next detached portion of
tube following is not obstructed The bag is now conveyed away by the cords W
to the drying cylinder Z. We would here observe that by our novel arrangement
of the cutter L creaser R and paster roller S, A length of tube is severed its end
pasted and folded and a bag completed with each revolving movement of the
shaft m, the speed of which is readily adjusted by change wheels, so as to
regulate and determine the length of the bag, without interfering with the position
or speed of the draw rollers G, and N
Having now described the nature of our said invention and the manner in which
the same is or may be performed we have to state that we do not restrict ourselves
to the precise details herein described or delineated, but what we believe to be
novel and original and therefore claim as the invention secured to us by the herein
before in part recited Letters Patent is.
Firstly, to actuate the paster roller C from one or other of the moving parts of
the machine for the purposes set forth.
Secondly, the application of a pair of adjustable rods, whereby templetes of
various sizes may be inserted between them to determine the width of the bag.

page_text: Thirdly the application of a cutter or breaker revolving at right angles to the
machine to sever the bag.
Fourthly to actuate the cutter and creaser from one shaft as herein described for
the purpose set forth.
In Witness whereof we, the said Thomas Bibby James Bibby John Baron
William Baron and Job Duerden, have hereunto set our hands and seals, the
twentieth day of September in the year of our Lord One thousand eight hundred
and eighty three.
