JOHN JOYCE, of Edmonton, in the County of Middlesex, Mechanical Engineer,
"IMPROVEMENTS IN THE CONSTRUCTION OF MACHINES FOR PACKING, MOULDING
AND COMPRESSING FLOUR, TEA, TOBACCO, AND OTHER SUBSTANCES INTO PACKETS
OR PARCELS PART OF WHICH IMPROVEMENTS ARE APPLICABLE TO OTHER
PURPOSES
"
My present Invention is in part founded upon the Invention for which Letters
Patent bearing date the Eighth day of August One thousand eight hundred and
seventy seven N° 3018 were granted to me and relates to improvements in the
construction of Machines for packing, moulding and compressing flour, tea, tobacco,
and other substances into packets or parcels, part of which improvements are also
applicable for the manufacture of paper bags.
The body of the Machine consists of a frame having a bed plate of any desired
shape or size. Beneath the said bed plate is mounted the main shaft by which the
mechanism of the machine is actuated through the medium of cams and other
contrivances as hereinafter described. Upon the upper side of the bed plate are
fixed two vertical columns or pillars connected at the upper ends by a fixed cross-
head and serving as guides to a moveable cross-head, within which is arranged a
rod carrying a rammer Block for compressing the material being packed. The last
mentioned cross-head, and with it the rammer, is moved up and down the said
guide columns by two rods the lower ends of which are provided with rollers

page_text: working respectively in the sides of two main cams. Upon the upper face of the
bed plate is placed the feed ring which is kept in position by anti friction rollers
suitably arranged and pivoted to the bed plate. The said feed ring carries any
desired number of moulds, and is actuated by means of levers which are so arranged
as to move the feed ring round any desired portion of a revolution to one revolution
of the main shaft. The said feed ring is arrested in the desired position at the end
of each stroke of the said levers by a suitable stop. In connection with each
mould is a filling tube round which the paper or wrapper is wrapped, these filling
tubes are moved at a certain point of the revolution of the feed ring out of the
moulds by means of two rods worked through the bed plate as hereinafter
described.
The first operation is the pasting of the wrapper and the folding of the same
round the filling tube, which is kept raised clear of the mould by a small moveable
catch connected to one of the sliding supports and resting, when in this position, on
the top of one of the guide pillars. The wrappers are arranged edgeways on a
suitable table and rest against an inclined support, sliding on the same, such support
being so connected with a hanging weight or equivalent contrivance as to be con-
tinually urged forward thereby forcing the supply of wrappers, as they are taken
off by the pasting pad, against a stop arm arranged at the front of the table, which
arm receives a rocking action from a shaft on which it is mounted, so as to alternately
hold and release the wrappers. The sliding support is prevented from forcing the
wrappers forward when the stop arm is moved away, by the gripping of the spindle
by which the weight is supported which is effected by a gripping lever operated by
a small cam on the main shaft or continuation thereof.
The pasting pad is arranged on one end of a slide which is worked backward
and forward within a dovetailed groove in an arm pivoted to a bracket piece
attached to the frame of the machine. The said backward and forward movement
of the slide is effected in the following manner. A vertical spindle mounted in
suitable bearings is provided at the lower end with a crank lever so arranged in
connection with a cam on the main shaft as to give the said spindle a partial
rotary movement which is transmitted to the slide through the medium of a lever
and suitable connecting rod the ends of the latter being respectively pivoted to the
slide and lever. When the slide is within the arm to its full extent the pasting
pad is situated opposite a rotating pasting roller which works, at one side, through
a slot in a reservoir or duct containing the paste. A spring is suitably arranged
to continuously urge the arm and slide forward, that is to say-towards the
pasting roller and supply of wrappers, but such forward tendency of the slide and
arm is checked by one end of a lever acting against a pin attached to the arm,
the said lever is carried on the upper end of a vertical spindle and to the lower
end of the latter is connected another lever arranged to work on the side of a cam
in which are cut a series of recesses, notches or indentations; when the end of the
said lever is caused to move up the inclined side of one of the recesses of the cam,
by the rotation of the same, the spindle will be partially rotated and will cause the
lever on the upper end thereof to bear against the pin on the arm and move the
latter back. The object of the above arrangement is as follows.-When the machine
starts the pasting pad is moved forward against the pasting roller and having
received therefrom a supply of paste it is, together with the slide and arm, moved
back as above described, and is carried by the slide until it is opposite the side of
the front wrapper when it is again moved forward, on its return it takes with it
the front wrapper (the paste on the pad causing the same to adhere) and proceeds
back with the same until the wrapper comes opposite the filling tube, when the
progress of the slide is arrested and it is again thrown back in order to allow
the wrapper to come into position against the side of the filling tube and the
wrapper having been taken off, as hereinafter described the above moveinents
of the slide and its connections are then repeated.-To a crank on the upper end
of a vertical spindle which is partially rotated by a cam on the main shaft, is con-
nected one end of a link connecting rod the opposite end of which is connected to

page_text: a side traveling on a suitable carriage or bracket and to the said slide is bolted a
vertical open ended box, being slightly larger but of the same configuration as the
filling tube, within the box and parallel to the back of the same is a plate faced
with india rubber, to the back of this plate is attached a tube which slides tele-
scopically into a tube closed at the outer end and projecting from, and fixed to, the
back of the box, within the two tubes is a spiral spring the rear end of which
bears against the end of the tube of the box whilst the other end of the spring
forces the plate slightly beyond the edges of the sides of the box. When the
wrapper has been brought opposite the filling tube as above described, the partial
rotation of the last mentioned vertical spindle will move the slide and box
forward towards the filling tube, and the plate coming into contact with the
wrapper is arrested and holds the same firmly against one side of the filling tube
and the sides of the box in advancing beyond the plate fold over the wrapper at
either side, this will leave the ends of the wrapper projecting beyond the further
side of the filling tube, and in order to bend the said ends one over the other to
form the joint, I employ two folding or wrapping arms which are constructed and
arranged as follows. The arm which first comes into action is pivoted to a suitable
bearing and is connected by means of a rod with one end of a bell crank lever,
which receives an intermittent oscillating motion from a vertical rod actuated by a
cam on the main shaft. That end of the arm which comes into contact with, and
folds the wrapper against the filling tube is furnished with a wide end of the same
depth or nearly so, as the wrapper, such end has a pad connected with a sliding
piece on the arm and the pad is by preference, brought to bear against the wrapper
by the action of a spring. The remaining edge of the wrapper which has deposited
on its inner surface a certain amount of paste from the pasting pad, is wrapped
over the filling tube and the edge of the opposite end of the wrapper, by the second
folding arm which is constructed in the same manner as that firstly described but
has in addition a blade attached to the widened end. This folding arm is mounted
on a spindle which through the medium of a crank and connecting link receives a
partial rotary motion from the slide to which the box above referred to is bolted.
When the blade on the end of the last mentioned folding arm arrives at the
extremity of its inward movement it will be situated over the joint, and in order
to cause the two edges of the wrapper constituting the same to adhere, a roller is
caused to travel over the said blade and by bearing against the same to firmly
press the said edges together, the said roller is mounted in the end of a vertical
bar which is raised at every revolution of the main spur wheel by a stud thereon,
and returns to its former position when clear of the stud by reason of its own
weight. When the wrapper is folded on the filling tube as above described, a
sufficient length thereof to form, when folded, the bottom of the packet projects
beyond the bottom of the filling tube and in order that the roller may bear with
sufficient force against that part of the joint, a flat bar is caused to move up
through the bed plate and mould to the back of such projecting portion of the
joint of the wrapper thereby providing sufficient resistance to the prossure of the
roller, the said fit bar is moved up at the desired moment by a lever actuated by
a cam on the main shaft. To separate the wrappers on the table in order to
prevent the pasting pad taking off inore than one at a time I conduct a blast of air
through a pipe to the edges of the said wrappers, at the time when the pasting pad
is about to take the front wrapper off, the air blasts are obtained from an air
pump the piston rod of which is connected with and actuated by, one of the rods
working the above mentioned moveable cross-head, or, the said pump can be
worked by a separate crank on the main shaft. The wrapping of the wrapper and
formation of the joint having been completed, by the above described operations,
the next object to be effected is the folding of the lower end of the wrapper, and I
prefer to arrange the mechanism for carrying this object into effect in such a
position that the filling tube with the wrapper will come into position to be operated
upon, at the time that the second following filling tube is in position for being
wrapped.

page_text: The mechanism for effecting the folding of the lower end of the wrapper is
constructed and arranged as follows. Two columns, each supporting an arm, are
screwed on, or otherwise attached to, the bed plate, one at each side of the feed
ring that is to say, opposite each other and respectively close to the inner and
outer peripheries of the ring, Two slides are arranged, on the arms, to work
opposite and towards each other. To the front of one of the said slides is fixed a
blade or plate which in its forward movement turns in one side of the projecting
end of the wrapper, and two projecting spring horns connected to the said slide are
so arranged that when they move forward with the said blade or plate they will
pinch and hold the wrapper at the sides of the lower edge of the filling tube.
Beneath the said blade or plate and connected to the same slide are two moveable
or expanding arms or levers, and into the said slide is also fitted a spindle carrying
a circular disc, or an equivalent therefor, by which motion is given to the last
mentioned arms or levers. The forward and return movements of the slide, for
effecting this part of the folding, are obtained by means of a bell crank lever con-
nected by a rod and lever with a cam on the main shaft. On the return movement
of the said slide, a crank on the spindle of the above mentioned disc engages with
a latch or catch on the arm and causes the moveable arms to expand and to throw
out the ears or corners of the bottom of the wrapper. As the above described
slide and mechanism connected there with returns, the slide on the second column
above referred to, advances. To the front of this slide is fixed a blade or plate
which folds over the remaining side of the wrapper and to each side of the said
slide is pivoted a small lever passing through a guide attached to the side of the
arm, the said levers are so shaped that when they have reached their position
outside the ears or corners of the bottom of the wrapper, they will drop slightly
and bring the said ears or corners into a suitable position to be caught by the
swinging arms as hereinafter described. The motion for effecting the forward and
return movements of the last mentioned slide is transmitted by means of levers from
the top folding mechanism as hereinafter described. At either side of the arm
carrying the last mentioned slide is arranged a vertical spindle on each of which is
mounted a hollow lever within which works a rod having at its outer end a plate or
block. To the said rods is connected by means of suitable levers a rod which is
moved vertically by a cam on the main shaft, and which causes the said rods to
slide forward in the hollow levers until they have reached the desired position, one
of the vertical spindles is then caused to partially revolve by a crank which is
connected by a rod to a lever which is deflected at the requisite time, by a lever
working on an inclined plate or cam on the side of the spur driving wheel ;-The
inner edge of each hollow lever is provided with teeth the teeth of one lever being
arranged to gear into the teeth of the other so that as one of them is moved by the
partial revolution of its vertical spindle as above described, it will act on the other
hollow lever so that they will move towards each other, this movement will cause
the plates or blocks at the ends of the sliding rods to come into contact with the
ears or corners of the bottom of the wrapper and will bend them over against the
Jast mentioned folding blade or plate which is then withdrawn by the action of
the slide. At this stage of the operation the vertical spindles, which are connected
beneath the bed plate, receive a slight upward movement from a cam on the main
shaft, thus forcing the said plates or blocks up against the folded end of the
wrapper. In some cases when this upward movement takes place a rod having at
its lower extremity a plate is lowered into the filling tube to the inside of the
folded end of the wrapper and by its weight acting in opposition to the said
plates or blocks ensures the proper pressing of the said folded end. The last
imentioned rod is suspended from one end of a lever which is pivoted near its
opposite end to a bracket connected to one of the rods actuating the before
mentioned cross head, by which means the required up and down action of the
rod carrying the plate is obtained at the proper time.
The operation of folding the bottom of the packet having been completed as
above described, the feed ring is again caused to travel and the progress thereof is

page_text: arrested when the filling tube comes beneath one end of an arm attached to one of
the rods actuating the cross head the said arm is then caused to descend, by the
action of the said rod and a tappet thereon pushes away the catch maintaining the
filling tube at the upper part of the guide pillars down which the said filling tube
descends partly by reason of its own weight and partly by the action of
the said arm until the wrapper, with the exception of that portion which is
afterwards, when folded to form the upper end of the packet, is within
the mould. The feed ring is then caused to travel another stage, when the mould
filling tube and wrapper will be beneath a hopper or funnel attached to a projection
from the before mentioned arm for releasing and pushing down the filling tubes,
the said hopper or funnel descends with the said bar and arm until the tube
portion thereof has entered the upper end of the filling tube, the quantity of tea
or other material to form the packet, is then placed therein and passes into the
filling tube when the hopper again ascends with the said bar and arm. The feed
ring is again moved forward until the mould arrives between the guide pillars of
the cross head, where it remains until the operation of ramming or compressing
the tea or other material within the wrapper is effected. The rod carrying the
rammer block or plate moves within a vertical boss in the centre of the moveable
cross-head and the upper end passes freely through an aperture in the fixed cross-
head. The said rod is constructed in two parts a portion of the upper part is
made hollow and the lower part is so arranged that it can be screwed more or less
into the upper part by means of an adjusting nut, in order to allow of the
adjustment of the pressure exerted by the rammer block or plate. As before
mentioned the moveable cross head is moved up and down the vertical guide
columns or pillars by two rods which are connected to either end of the said cross
head and are actuated by means of cams on the main shaft When the rammer
block or plate is about to come into contact with the material to be compressed, it
is desirable that the rod carrying the said rammer block or plate should be locked
in position in the cross-head and this is effected by the following means-To the
front of the moveable cross-head is fixed a case containing a bolt through a slot in
which passes a fixed bar so shaped that as the moveable cross-head descends the bolt
will be moved forward through the same into a hole formed in the rod of the
rammer block or plate thus locking the same, and on the ascent of the cross head
the bolt will be moved back and the rod released, this arrangement of locking and
unlocking the said rod allows of the rigidity of the rammer block or plate at the
required time whilst it also permits of the employment of a lever for the purpose of
obtaining a longer upward stroke of the rammer rod so as to lift the rammer
block or plate clear of the other mechanism when its stroke is completed. The
last mentioned lever is pivoted near one end to the moveable cross head, the longer
arm of the same being hinged to the upper end of the rammer rod by a link whilst
the opposite arm is hinged to one end of a loose vertical rod working through a
hole in the bed plate and having a nut on the lower end which prevents it from
passing entirely through the same. This loose rod is made of such a length that
its upward motion will be arrested before that of the cross head so that the end of
the lever pivoted to the loose rod will stop before the pivot point of the same and
the opposite end, thus causing the said lever to move on its pivot and to raise the
raminer rod. Passing through the bed plate between the vertical columns serving
as guides to the moveable cross head are two rods the lower ends of which are
connected together so that they are raised and lowered by the same cam, these rods,
immediately the rammer commences to bear on the material in the packet, move
upwards and coming into contact with the supports at the sides of the filling tube
lift the same until it is in a position to be again fixed at the top of its guide pillars
by the before mentioned catch which is turned into position by coming into
contact with a fixed projection.
When the operation of ramming is completed and the rammer rod withdrawn
the feed ring is again moved forward and the mould brought into position for the

page_text: folding of the top end of the packet, which is effected by the following arrangement
of mechanism.
Two columns each supporting an arm, are screwed on, or otherwise attached to,
the bed plate, one at each side of the feed ring, that is to say, opposite each other
and respectively close to the inner and outer peripheries of the said ring. Two
slides are arranged on the said arms, to work opposite and towards each other.
To one of the said slides are connected two moveable or expanding arms or levers,
and into the same slide is also fitted a spindle carrying a circular disc or an
equivalent therefor by which motion is given to the last mentioned arms or levers.
The forward and return movements of the slide are effected by a cam on the main
shaft through the medium of levers. When the slide moves forward the front
ends of the expanding arms or levers come into contact with one side of that
portion of the wrapper which projects above the top of the mould and turns the
same inwards over the top of the material-On the return movement of the said
slide a crank on the spindle of the above mentioned disc engages with a latch or
catch on the arm and causes the moveable arms to expand and throw out the ears
or corners of the top of the wrapper. A stop is provided to prevent the moveable
arms being thrown out or expanded to a too great extent. As the above slide
and mechanism connected therewith returns the slide on the second column
above referred to advances towards the top of the mould. To the front of this
slide is fixed a blade or plate which folds over the remaining side of the wrapper.
To each side of the said slide is pivoted a small lever passing through a guide
attached to the side of the arm, the said levers are so shaped that when they have
reached their position outside the ears or corners of the top of the wrapper, they
will rise slightly and bring the said ears or corners into a suitable position to be
caught by the swinging arms as hereinafter described. The forward and return
movements of this slide are effected by a lever which is connected by links with
another lever actuated by a cam on the main shaft. To the slide is attached one
end of a rod the opposite end of which is connected to an oscillating beam whereby
motion is transmitted by a second rod to the slide of the second portion of the
bottom folding mechanism. At either side of the arm carrying the last mentioned
slide is arranged a vertical spindle on each of which is mounted a hollow lever and
within each of the latter works a rod having at its outer end a plate or block to
the said rods is connected by means of a suitable lever a bar which is moved
vertically by a cam on the main shaft and causes the said rods to slide forward in
the hollow levers, until they have reached the desired position, one of the vertical
spindles is then caused to partially revolve by a crank which is connected by a
rod or link to a lever which is deflected at the requisite time by another lever
working on an inclined plate on the side of the spur driving wheel. The inner
edge of each hollow lever has teeth formed on it which gear into each other so that
as one of the hollow levers is moved by the partial revolution of its vertical
spindle as above described it will act on the other hollow lever, so that they will
move towards each other, this movement will cause the plates or blocks at the
ends of the sliding rods to come into contact with the ears or corners of the top of
the wrapper, and will turn them in on to the last mentioned folding blade or plate,
which is then withdrawn by the action of the slide. At this stage of the operation
the vertical spindles which are connected beneath the bed plate, receive a slight
downward movement from a cam on the main shaft, thus forcing the said plates or
blocks down on to the top of the packet for the purpose of perfecting and
completing the formation of the same. The folding mechanism is then returned
to its normal position and the feed ring is moved another stage which brings the
mould and finished packet over an opening in the bed plate, through which the
packet is forced from the mould by a rod worked by a lever which receives the
requisite upward and downward movement from one of the main cams. The
finished packet is received on an endless band or other suitable contrivance or
receptacle.

page_text: The whole of the above described operations are effected in connection with the
various filling tubes and wrappers according to their position during one revolution
of the main shaft, and are repeated during each subsequent revolution, such inain
shaft being driven by continuous motion by steam or other power.
I will now proceed to refer to the accompanying drawings from which the
nature of iny said Invention will be more clearly understood. Figure 1. is a plan
of the machine. Figure 2 is a front elevation of the same. Figures 3 and 4 are
end elevations in which the wrapper table D and a portion of the mechanism for
effecting the supply of wrappers are omitted in order that the remaining
mechanism may be clearly shown Figure 5. is a plan of the top and bottom
folding mechanism, and Figure 6. is an elevation of the same, as seen from the
line A. B. in Figure 1. Figures 7 to 12 are detail views of the bottom folding
mechanism. Figure 3 shows details of the mechanism for locking the weight
actuating the sliding inclined support on the wrapper table. Figure 3b shows
details of the locking arrangement of the rammer. B is the frame of the machine
and B is the bed plate. The main shaft B2, is mounted in suitable bearings A
and is driven by the first motion shaft A¹ through the medium of pinion R, and
spur wheel R, A are the fast and loose pulleys on the shaft A'. The feed ring C:,
which is placed on the upper face of the bed plate, is kept in position by the anti-
friction rollers U, and carries a number of moulds c. in this case eight. The said
ring C. is moved partially round at each revolution of the main shaft, so that the
moulds c. may be successively brought into position to be operated upon by the
various arrangements of mechanism for effecting the wrapping, folding, ramming
and so on. The said movement of the ring C, is effected by means of the
levers N'. N. the latter having a stud on one end which works within a slot in
the former, the vertical spindle of the lever N has a crank attached to the lower
end which crank passes into an aperture in a sliding bar arranged beneath the bed
plate and moved backward and forward by the lever N which is deflected by the
stud roller T. fixed to the spur wheel R., so that when the main shaft B2 is about
the completion of its revolution the stud roller T acting on the lever N will drive
it to one side and the sliding bar, being moved thereby, will cause the spindle of
the lever N to partially revolve, thus moving the levers N¹. N". forward, and
the loose pawl n. on the end of the lever N¹ dropping into one of the catch
holes n in the feed ring will move the latter forward until the moulds e are
respectively in position opposite the various arrangements for effecting the next
operations. At this stage a stop or bolt n is forced upwards by a spring through
an aperture in the bed plate into one of the catch holes n' and thus maintains the
feed ring rigidly in position. The said stop n" is connected to the upper end of a
rod--the lower end of which has thereon a stud, pin or other suitable contrivance,
so arranged that when the feed ring is about to be moved as above described, the
enlarged portion of cam 5 will bear against such stud and depress the rod until
the stop is clear of the feed ring. When the stud roller T. is clear of the
lever N the levers N¹. N". have completed their forward stroke and are brought
back to their normal position by the action of a spring on the before mentioned
sliding bar.
c are the filling tubes which are arranged in connection with their
respective moulds and have attached to the upper part supports c" which slide up
and down the guide pillars c
The first operation, that of pasting and wrapping the wrapper round the filling
tube is effected in the following manner-The filling tube at this stage is kept
raised clear of the mould by a small moveable catch c², which is pivoted to one of the
supports c, and is turned so as to rest on the top of one of the guide pillars c¹¹l.
The wrappers are arranged on the table D. and rest against the sliding inclined
support D which is connected by a cord or other analogous contrivance with a
hanging weight so that it is continually urged forward along the table as the
wrappers are taken off, thus forcing the wrappers against a stop arm d. which
receives a rocking action from its shaft dx, and thus alternately holds and releases
the wrappers. When the latter are released the action of the weight d is arrested

page_text: by the mechanism shown detached in Figure 3a, in the following manner, the cord
supporting the weight or by preference a rod yll forming a continuation of the
cord passes through the centre of a boss y" carried by a bracket; to the said boss
is pivoted at y' one end of a bell crank lever y through an aperture in which the
rod y passes, the free end of the lever y is bent up at y so that when the pro-
jecting party of the cam 8 acts on the end y2 of the lever the latter will be
slightly turned on its pivot and the rod y will be grasped between the edge of
the boss and that of the aperture in the lever.
The pasting pad d' is arranged on the end of the slide d¹ working backward
and forward within a dovetailed groove in the arm d³ pivoted to bracket piece d
attached to the frame of the Machine. A vertical spindle d¹¹, mounted in suitable
bearings is provided at the lower end with a crank lever dv. to which is fixed a
pin passing through a slot in one end of the rod d¹ the opposite end of such rod
working on, or in, the cam 7. whereby the said rod is moved backward and forward,
by these means a partial backward and forward rotary movement is given to the
spindle which communicates a backward and forward movement to the
slide through the medium of a lever d¹² and connecting rod d³ the ends of
the latter being respectively pivoted to the slide and lever d¹².
When the slide d is within the arm to its full extent, the pasting pad d¹ is
situated opposite the rotating pasting roller d³ which works, at one side through
a slot in the paste reservoir or duct d². The pasting roller d³ is made of any
suitable material, and, is, by preference, mounted vertically in suitable bearings.
On the upper end of the spindle of the said roller is fixed a ratchet wheel above
which is loosely mounted a lever d' having a pawl pivoted thereto which takes
into the teeth of the ratchet wheel, the said lever is of sufficient length to be
caught by the sliding supports of the filling tubes as the feed ring revolves and
being thereby forced on one side will turn the pasting roller d³ a short distance,
the lever d' is, when free, returned to its normal position by a spring.
A pulling spring being connected at one end to a fixed bracket and at the other
to the pivoted arm da will continuously urge the said arm and with it the slide du
and pasting pad d', forward towards the pasting roller or supply of wrappers
according to the position of the slide d", however, such forward movement is
checked by one end of the lever d¹ acting against a pin attached to the arm d³,
the said lever is carried on the upper end of a vertical spindle d₁ to the lower end
of which the lever d¹. is connected and arranged to work on the side of the cam 6
in which are cut a series of recesses, notches or indentations when the end of the
lever d¹ is caused to move up the inclined side of one of the said recesses of the
cam by the rotation of the same the spindle d¹s will be partially rotated and will
cause the lever d to bear against the pin and to move the arm d³ and slide d",
with pasting pad, back from the pasting roller or supply of wrappers
The action of the above described mechanism for pasting the wrappers and
feeding the same to the filling tubes is as follows.-On the rotation of the main
shaft the lever d¹ entering one of the recesses of cam 6, the slide d" will be
moved forward by the spring so that the pasting pad will come into contact with
the pasting roller and receive a supply of paste, the lever d¹e then clears the recess
of cam 6 and the slide d" and pasting pad are brought back to their former
position, the cam 7 acting on the rod do and thereby on the lever dv and
spindle dwill cause the lever d¹ and connecting rod is to move the slide d
towards the supply of wrappers, when the said slide opposite the edge of the
front wrapper the action of cam 7 on rod d¹º, ceases, and the lever d¹ again
entering one of the recesses in cam 6 the spring will move the slide d" and
pasting pad forward until the latter, which is made moveable so as to adjust itself
to the position of the wrappers, comes into contact with the side edge of the front
wrapper, at this stage the shaft dx is rocked by the action of the cam and rod 9,
so that the stop arm d. will be moved back from the wrappers and rod d¹ having
cleared the recess of cam 6 the slide d" is moved back and takes with it the front
wrapper which the paste causes to adhere to the pasting pad. At the time of

page_text: taking off the wrapper, as above described, a blast of air is directed beneath the
wrappers so as to separate the same, the air blast is obtained from an air pump O
the piston rod o of which is connected to, and actuated by, the rod M¹, the
conducting tube is shown at o'. At this point cam 7 again comes into action and
causes the slide d¹¹ to be returned into the arm d³. until the wrapper carried by
the pasting pad is brought opposite the filling tube.
The Wrapper having been brought, as above described in front of the filling tube
the open ended box d³ advances and wraps the former partially round the latter
The said box d³ is bolted to the slide de which travels on its bracket and is
connected by the link connecting rod d to the Crank on the vertical spindle f
actuated by the lever vand cam v¹ on the main shalf. Within the Box d³ is the
plate D to the back of which is attached a tube which slides Telescopically into a
tube projecting from the back of Box d³, the plate D2. is kept forward within the
box by the action of a spring, this arrangement of mechanism effects the partial
wrapping of the wrapper round the filling tube in the following manner, The
cam which is shewn arranged on the side of one of the main cams comes into
contact with the Lever and partially turns the same on its pivot vx, and thus
brings it into contact with the end of a rack and moves the same in its guides, and
this rack gearing into a pinion on the lower end of the spindle f, causes the same
with its crank to partially rotate thereby moving the link d', slide do, and open
ended box d³, inwards, the plate D2 on coming into contact with the wrapper
which it holds against the filling tube, is arrested, and as the sides of the box d³
advance beyond the said plate they fold over the wrapper at either side against the
filling tube.
The above operation having been effected the two ends of the wrapper will be
left projecting beyond the filling tube, and these ends are bent one over the other
by two folding or wrapping arms e* and e¹ which are pivoted at el to a suitable
bearing. The arm e¹ is connected by means of a rod e. with one end of the bell
crank lever e' which receives an intermittent oscillating motion from the vertical
rod e actuated by the cam 3. One end of the arm e¹ has fixed to it a bar or
similar contrivance of the same depth, or nearly so, as the wrapper, and in con-
nection therewith is arranged a pad which is hinged to the sliding piece e³ on the
said arm e such pad being brought to bear against the wrapper by the action of
the Spring e¹0 on the sliding piece e. The remaining edge of the wrapper is folded
over by the arm el. pivoted at e", its spindle receiving a partial rotary motion
through the medium of the crank and link e from the inward movement of slide dª
or, this movement of arm e¹ can be effected by a separate cam, as will be well
understood. When the blade e¹¹¹ on the end of arm e' is over the joint of the
packet and in order to cause the edges of the wrapper to adhere, a roller on the
bar F travels over the blade e¹¹ and, by bearing against the same, firmly presses
the edges together, the bar F is raised, at the desired moment during each revolution
of the main spur wheel by a stud R" or by means of a separate cam mounted on
the main shaft, the flat bar which moves into position behind the projecting part of
the joint is shown at f¹ this bar is moved up at the desired moment by the lever f"
actuated by cam 4, several of the arrangements of mechanism hereinbefore
described are shown detached in the accompanying drawings, as follows. Figure 1ª
is a vertical section of the folding box do and figures 1b and 1c, are respectively back
view and plan of the same; Figure 1ª is a detached sectional view of a mould and
filling tube, and Figures 1'. and 1º. are respectively plan and side view of the same,
and mechanism connected therewith.
The wrapping and formation of the joint having been thus completed the feed
ring is moved, another stage, however, in the arrangement shown in the Drawings
nothing is effected here, but on reaching the next stage the filling tube will be in
the desired position for effecting the folding of the lower end of the wrapper.
The mechanism for effecting this object is shown in Figures 7 to 12 of the
accompanying drawings, Figure 7 is a plan of that part of the bottom folding
mechanism which first Comes into action, Figure 8 is an elevation of the same and

page_text: Figures 9 and 10 are respectively a sectional elevation and end view. Figure 11
is a plan view of that part of the mechanism which completes the folding operation
and Figure 12 is an elevation of the same. Figures 5. and 6. are respectively plan
and elevation of the combined mechanism for folding the bottom and top ends of
the packet. The same Letters of reference indicate like parts in the said Figures.-
I will now describe the first part of the said mechanism. To the bed plate is
attached a column A supporting an arm A' on which is arranged a slide B having
at the front end thereof a blade or plate E., to the said slide are connected two
projecting spring horns or supports F. F. and beneath the said blade or plate E
and connected to the slide B are two moveable or expanding arms or levers C. C¹.-
The Spindle of the disc D is fitted within the slide B so as to be capable of turning
freely therein. On the forward movement of the slide B the plate E comes into
contact with and turns in one side of the projecting end of the wrapper, the
horns F. F. serve to pinch and hold the wrapper at the sides of the lower edge of
the filling tube, the folding over of the said side having been effected, the slide B
commences to return and as it does so the crank a¹. on the Spindle of the disc D
engages with a latch or catch b¹. on the arm A' thereby turning the disc D to
which are pivoted two links d. d. respectively connected to the expanding
arms C. C. so that as the said disc turns the arms will be caused to expand and to
throw out the ears or corners of the bottom of the Wrapper the disc D and
arms C. C'. are brought back to their normal position by a stud a². on the crank a¹.
coming into contact with a bracket a. The forward and return movements of the
slide B are effected in the following manner. A Bell crank Lever g¹. suitably
pivoted has one end arranged to work within a slot in the Slide and the opposite
end is connected to a beam lever g. pivoted to a suitable bracket, the opposite end
of the said lever g. works on, or in, a cam 6 on the main shaft, so that when the
last mentioned end of the lever g. approaches the centre of motion of the cam the
slide B will be advanced and vice versa.
I will now describe the mechanism for completing the folding of the lower end
of the packet. As the slide B returns as above described, the slide I' on the
column G advances; to the front of the slide I' is fixed the blade or plate i and
to each side of the slide is pivoted a small lever I passing through guides attached
to the side of the arm G¹. As the slide I' advances the plate i comes into contact
with the remaining projecting side of the wrapper and folds it over and the shape
of the levers I" is such that they will drop within their guides at this point and
will bring the ears or corners of the bottom of the wrapper into a suitable position
to be caught by the swinging levers as hereinafter described. The advance and
return movements of the slide 1' are effected by the following means. To the
slide I' is attached a rod Q. the opposite end of which is connected to one end of a
beam lever Q, actuated by the top folding mechanism as hereinafter described or
the desired movements of the slide can be effected by means of a separate cam on
the main shaft, as will be well understood. At each side of the arm G¹. is arranged
a vertical spindle shown respectively at H. and H¹ in Figure 12., on these Spindles
are mounted the hollow levers J. J. within which work the rods j. j'. having at
their outer ends the plates or blocks . The rods j. j. are connected to the
links K. K. the opposite ends of which are pivoted to the shoe K". which slides
on the arm R. pivoted to the forked rod L which is jointed to one end of the
lever M. keyed or otherwise connected to the rocking shaft N on the opposite end
of the latter is mounted one end of a small lever N¹ on the other end of which is
a stud working within a slot in the lever O which is connected to the rod T
working on cam 1 on the main shaft so that as the rod T is raised by the said
cam the rods j j¹. are caused to slide forward in the Hollow levers J. J'. until they
are opposite the before mentioned ears or corners of the bottom end of the wrapper.
On the inner edges of the levers J. J¹ are formed a series of teeth, the teeth on
cach lever gearing into each other, and on the spindle H of the lever J'. is a crank
which is connected by a rod to a rocking lever S¹. to which is connected one end
of a lever the opposite end of which is so arranged that it will, at a certain point

page_text: of revolution, bear against an inclined plate or cam on one side of the spur wheel,
so that as the end of the lever moves up the incline of the said plate it will deflect
the lever S. which causes the Spindle H and with it the lever J. to partially
revolve a similar action being transmitted to the lever J. on the spindle H¹. until
the ends of the sliding rods j. j. meet after having turned down the ears or corners
of the wrapper against the blade or plate i which at this point is withdrawn by
the return action of the slide 1. The lower ends of the spindles H. H'. are con-
nected together by means of a cross-bar and are continued in the form of a rod
attached to the latter which rod is at this point of the operation raised by the
cam 2, thus forcing the plates or blocks up against the folded end of the wrapper.
The spindles H. H. are arranged so as to be capable of turning in holes in the said
cross bar.
In some cases I employ the rod W which when the upward movement of the
blocks lastly described takes place, is lowered into the filling tube to the inside of
the folded end of the wrapper so that a plate at the end of the said rod will act in
opposition to the upward movement of the said plates or blocks and ensure the
proper pressing of the said folded end. The said rod W is suspended from one
end of a lever W. pivoted to a guide bracket W¹. connected to the rod M' by
which means the rod W is moved up and down at the required intervals by the
movement of the said rod M².
The folding of the bottom of the wrapper having been completed as above
described, the feed ring is moved another stage. The filling tube will now be
beneath the arm J attached to the rod M¹. so that on descending with the latter a
tappet on the end of the arm J, pushes the catch c² off the top of the guide pillar,
thus allowing the filling tube to slide down its guide pillars, partly by reason of its
own weight and partly by the action of the said arm J, until the wrapper, with the
exception of that portion which is afterwards, when folded, to form the upper end
of the packet, is within the mould c the arm J. then ascends with the rod M'.-
This having been effected the feed ring is moved another stage thereby bringing the
said mould, filling tube and wrapper beneath the hopper or funnel J1 attached to a
projection from the arm J with which the hopper or funnel descends until the tube
portion thereof has entered the upper end of the filling tube, the tea or other
material to be packed is now passed through the funnel into the filling tube and on
to the folded end of the wrapper, the Hopper or funnel then ascends with the
arm J,
In some cases when it is not required to weigh the material to be packed I
employ in connection with the said Hopper or funnel a measuring apparatus con-
structed on the same principle as the ordinary measuring contrivance used in
connection with shot flasks, the free end of the lever actuating the slides, being
moved, as required by the feed ring or by a separate cam, as will be well under-
stood.
The feed ring is again moved another stage, thereby bringing the mould into
position for ramming between the guide pillars K. K¹. and beneath the moveable
cross-head L. The said pillars K. K¹. are connected at the upper ends by a fixed
cross head L and the moveable crosshead L' carrying the rammer K2, is arranged
to move up and down the said pillars. The rod of the rammer block or plate K². is
arranged within a vertical boss in the centre of the moveable crosshead L'. and the
upper end of the said rod passes freely through an aperture in the fixed crosshead
L. The said rod is constructed in two parts, a portion of the upper part being made
hollow and the upper end of the lower part is so arranged that it can be screwed
more or less into such hollow portion by means of an adjusting nut, so that the
adjustment of the pressure exerted by the rammer can be effected. To the moveable
crosshead L' are attached the rods M. the opposite ends of which are provided
with rollers which work on or in the main cams QQ. by which means the move-
able crosshead is moved up and down the guide pillars K. K' at the desired time.
When the rammer block or plate is about to come into contact with the material to
be compressed, it is desirable that the rammer rod should be locked in position in

page_text: the moveable crosshead and this is effected by the arrangement of mechanism shown
detached at Figure 3b. A case containing the bolt l' is fixed to the front of the
moveable crosshead and through a slot in the said bolt passes the fixed bar l.
attached to the crosshead L. As the moveable crosshead L³ descends one end of
the slot in the bolt 1. bears against the top incline of the bar 7. the said bolt being
thereby moved forward into a hole formed for its reception in the rammer rod thus
locking the same to the crosshead L., and on the ascent of the latter, one end of the
bolt bearing against the lower incline of the bar l. the said bolt will be moved
back and the rod released. m². is a lever employed for the purpose of obtaining a
longer upward stroke of the rammer rod than would be effected by the moveable
crosshead so as to lift the rammer block clear of the other mechanism. The lever
m'. is pivoted near one end to the moveable crosshead and one end thereof is hinged
to the rammer rod by a link, whilst the opposite end is hinged to the loose rod m,
working through a hole in the bed plate, the lower end having a nut thereon to
prevent it from passing through the same. The rod m is of such a length that its
upward motion will be arrested before that of the crosshead L. so that the end of
the lever m¹ which is pivoted to the rod m, will stop before the pivot point of the
same, thus causing the lever m². to turn on its pivot and to raise the rammer. The
rods . . pass through the bed plate between the columns K. K. and the lower
ends thereof are connected together so that they are raised and lowered by the
cam I, which, immediately the rammer commences to bear on the material in the
packet, moves the rods upwards so that their ends coming into contact with pro-
jections at the side of the filling tube will lift the latter until it is in a position to
be again fixed at the top of its guide pillars, which is effected by the catch c².
coming into contact with the fixed projection M, and thereby turned into the
required position.
The operation of ramming having been completed the feed ring is moved another
stage and the mould containing the packet is brought into position for the
projecting portion of the wrapper to be folded to form the top of the packet. The
arrangement of mechanism for effecting this object is similar to that already
described for folding the bottom of the packet [the same letters of reference being
employed for indicating like parts] with the exception of the following modifications.
The plate E at the end of the slide B and the horns F. F. in that part of the
Mechanism which first comes into action are dispensed with, and the backward
and forward movements of the slide are effected in the following manner. To the
said slide is connected a lever g³. pivoted beneath the bed plate, the lower end of
the said lever is connected by means of links to a horizontal lever which is
pivoted about its centre and is connected at its outer end to a bell crank lever h.
which is actuated by the cam 10. When box cams are employed the spring h²,
which connects the upper end of the lever h. to the upper end of lever h¹ is
dispensed with.
The apparatus, for completing the folding of the top of the packet, is also similar
to that hereinbefore described for completing the folding of the bottom of the
packet, with the following modifications. The shoe K". and mechanism connected
therewith for actuating the rods j j. are arranged above the other mechanism and
the plates or blocks 11 111. are fixed the reverse way, so that they may be pressed
down on the top of the packet which operation is effected by the T shaped
lever B¹, one end of which is connected to the spindles H H. whilst the other end
of the lever works on or in the cam B. so that when the cam moves the lever B¹.
so as to compress a spring fixed beneath the bed plate the said blocks j. j will
press down the top of the packet and when the action of the said cam ceases the
blocks and lever B¹. will be brought back to their former position by the action of
the said spring. The slide I is connected to one end of the lever g2 pivoted
beneath the bed plate, the opposite end of such lever being connected by means of
links g. to a horizontal lever which is pivoted about its centre and is connected at
its outer end to a bell crank lever h¹. which is actuated by the cam 11. by these
means the said slide is moved backward and forward as required. The said slide

page_text: is connected by a rod Q to one end of the beam lever Q1 from which motion is
transmitted through the medium of the link Q to the slide I' of the second part
of the bottom folding mechanism. The sliding rods j. j are actuated in a
manner similar to that of the corresponding rods of the bottom folding mechanism,
the lever T. being connected to the lever T¹ on the rocking shaft O₁ the opposite
end of this lever T is connected to a rod T which works on or in cam 1. so that
as the rod T is raised by the said cam the rods in the hollow arms are caused to
slide forward in the manner hereinbefore described. The closing of the said arms is
effected by the opposite end of the rocking lever to that which completed the
bottom folding operation.
The folding of the packet having been thus completed the feed ring is moved
another stage thereby bringing the mould and packet over an opening in the bed
plate, through which the packet is forced by the rod P which is moved up and
down by the lever P¹ operated by an arm P worked by the main cam Q. The
finished packet may be received on an endless band or other suitable contrivance
or receptacle.
In some cases instead of securing the filling tubes when they are out of the
moulds on the top of their guide pillars by means of the catches c². I arrange a
circular support above the feed ring and connect the same by pillars or brackets to
the bed plate this support will extend from a short distance in front of the position
occupied by the filling tubes when lifted clear of the moulds by the rods i i to
that part of the table where the filling tubes are caused to enter the moulds.
When the filling tubes are raised by the rods ii and in their upward
movement the projection on one side comes into contact with the bevel face
of a spring latch forming a continuation of the said circular support and forces
the said latch back until the projection has passed when the latch springs to
its normal position and acts as a support to the said projection and filling tube, at
this point the upward movement of the rods i i ceases, and on the feed ring being
moved the filling tube will be moved forward by its guide pillars and maintained
in its raised position by its projection resting on the circular support as described.
On the filling tubes arriving at the point where they should enter the moulds they
pass off the end of the circular support and slide down their guide pillars into the
moulds by reason of their own weight assisted if desired, by the arm J.
In some cases I form on, or attach a bracket to the outside of the front edges of
the sides of the box d³. and to the outer edge of each bracket I hinge one side of
an elastic pad the opposite side of which is arranged to project inwards, so that as
the said box advances the pads will press against and fold over the sides of the
wrapper against the filling tube during the advance of the said box the pads when
pressing against the wrapper are prevented from moving back by the edges of the
sides of the box, but on the return movement of the latter the pads are free to
open slightly by turning on their hinges, such movement being regulated by
suitable stops.
A detached view of a packet as folded by the mechanism herein before described
is shown on Sheet III of the accompanying drawings.
The whole of the operations, hereinbefore described, are effected, about the same
time in connection with the various filling tubes and wrappers according to their
position, during one revolution of the main shaft, and are repeated during each
subsequent revolution, the said main shaft being driven continuously by steam or
other power.
For the manufacture of paper bags, the feed ring and mechanisin connected
therewith for regulating its movements are substantially the same as hereinbefore
described, with the exception that the mould is dispensed with and the filling tube
or other anologous contrivance is, by preference, fixed in a suitable position, and
the remaining mechanism for completing the formation of the bags will be the
paper table, the mechanism for supplying papers to the filling tubes and for folding
and pasting the same and the apparatus for effecting the folding of the lower ends.
The ring may be, if desired, arranged in connection with a double set of the

page_text: arrangements of mechanism lastly described so that two sets of paper bags are
manufactured at the same time in which case the two sets of mechanism for
effecting the folding of the bottoms of the bags are arranged in connection with
each other in a similar manner to that hereinbefore described for connecting the
bottom and top folding mechanism, or four or more sets may be arranged in
connection with the ring.
