Improvements in the Manufacture of Pockets for Cigarettes and the
like, and in Apparatus therefor.
We, JOHN DAVIDSON, Paper Maker, and WILLIAM SMITH MURRAY, Engineer,
both of Mugiemoss Works, Aberdeenshire, do hereby declare the nature of this
invention to be as follows:
The object of this invention is the manufacture of the pockets or five sided
rectangular boxes used for holding cigarettes and other articles.
Rectangular strips of paper of suitable dimensions are placed in a box. When
the machine is started the top strip of paper is gummed on its two edges through-
out about half its length by two jointed levers pivotted to the frame of the
machine at each side of the box; the ends of the levers are kept supplied with
gum by their coming in contact with rollers revolving in a trough containing
gum.
Above the box is a flat perforated disc connected with an exhaust fan by a
pipe. The top strip of paper is laid hold of by the disc and is conveyed im-
mediately above a slot. The length of this slot is equal to or greater than the
width of the strip and above it is a vertically moving plunger or blade whose
width is less than that of the paper. The plunger in descending forces the
paper through the slot whilst two helical guides turn in the edges at right angles
to the body of the pocket; first the ungummed edges and then the gummed
edges on the top of them and press them against the sides of the plunger.
Beneath the slot are two endless bands, one on each side, these bands are caused
to move downwards by the motion of the plunger as it descends but on its return
they retain the pockets and carry them through guides to a travelling felt.
The top strip of paper in the box is kept at the proper height by the bottom of
the box being raised by a slowly moving screw which is actuated by a ratchet
wheel whose ratchet is carried by a lever. The end of this lever engages with
a cam groove on a shaft geared to another shaft actuating the plunger by means
of another cam groove.

page_text: Executors of John Davidson, Paper Maker, deceased, and WILLIAM SMITH
MURRAY, Engineer, all of Mugiemoss Works, Aberdeenshire, do hereby declare
the nature of this invention and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement:-
The object of this invention is the manufacture of the pockets or five sided
rectangular boxes used for holding cigarettes and other articles.
Rectangular strips of paper of suitable dimensions are placed in a box. When
the machine is started the top strip of paper is gummed on its two edges through-
out about half its length by two jointed levers pivotted to the frame of the
machine at each side of the box; the ends of the levers are kept supplied with
gum by their coming in contact with rollers revolving in a trough containing
gum.
Above the box is a flat perforated disc connected with an exhaust fan by a
pipe. The top strip of paper is laid hold of by the disc and is conveyed im-
mediately above a slot. The length of this slot is equal to or greater than the
width of the strip and above it is a vertically moving plunger or blade whose
width is less than that of the paper. The plunger in, descending forces the
paper through the slot whilst two pairs of helical guides turn in the edges at right
angles to the body of the pocket; first the ungummed edges and then the gummed
edges on the top of them and press them against the sides of the plunger.
Beneath the slot are two endless bands, one on each side, these bands are caused
to move downwards by the motion of the plunger as it descends but on its return
they retain the pockets and carry them through guides to a travelling felt.
The ton strip of paper in the box is kept at the proper height by the bottom of
the box being raised by a slowly moving screw which is actuated by a ratchet
wheel whose ratchet is carried by a lever. The end of this 'lever engages with
a cam groove on a shaft geared to another shaft actuating the plunger by means
of another cam groove.
Figure 1 is a front elevation of the machine, Figure 2 is a side elevation, and
Figure 3 a horizontal section on the line 3-3 Figures 1 and 2. These figures
are th of full size.
Figure 4 shows the blank or piece of paper from which the pocket is made.
Figure 5 is a front view of a partly made pocket, and Figure 6 an edge view of
a completed pocket. Figure 7 is a left hand elevation, and Figure 8 a front
elevation of the guides, and Figure 9 is a section on the line 9-9 Figure 8.
Figures 10, 11 and 12 are sections (on the lines 10-10, 11-11, and 12-12,
Figures 7, 8 and 9,) of one of the back guides, and Figures 13, 14 and 15 are
sections (on the lines 13--13, 14-14, and 15-15, Figures 7, 8 and 9,) of one of
the front guides. Figures 4 to 15 are full size. In Figures 10 to 15 the parts
below the plane of section are omitted.
Figure 16 is a front elevation, and Figure 17 a plan of the gumming apparatus.
These figures are half size.
The box a (Figures 1, 2, 3, 16 and 17) contains a pile of strips of paper b
(Figure 4). On each side of the box a are troughs c containing gum in which
rollers are partly immersed. d are blades fixed to shafts pivotted on.
arms, d² fixéd to rocking shafts ³ actuated by connecting rods d pivotted to
arms d fixed to them: ds are slotted arms fixed to the shafts d¹ and d is a pin
passing through these slots and a slot in the fixed bracket 8.
When the parts
are in the positions shown in full lines in Figure 16 the blades d are in contact
with the gummed rollers c¹ but when in the positions shown in dotted lines they
are in contact with the edges of the top sheet of paper b in the box a.
d⁹ are
arms fixed to the shafts d³ and carrying pawls do engaging with ratchet
wheels fixed to the axes of the rollers c¹ so that the rollers are gradually
turned by the oscillations of the shafts.
The upper ends of the connecting rods d are pivotted to a crosshead e carried
by a pine fixed to a slide e3 working in a vertical slot in a bracket e fixed to
the frame. e5 is a roller on the pin e² and pressed by the spring e6 onto the

page_text: cam e fixed to the shaft f. This shaft has fixed to it a toothed wheel f¹ gearing
with a pinion f on the main shaft f3. g is a perforated pad fixed to the pipe gl
which slides telescopically in a fixed pipe g² connected to an exhaust fan which is
not shown. The pipe g' is connected by a lug g³ to a rod g' carrying a roller g³
working in a cam groove in the wheel h fixed to the vertical shaft h₁ and driven
from the shaft through the bevel pinions f and h². The rod g carries at
its end a pawl gearing with a ratchet wheel j whose shaft has fixed to it a
bevel pinion j gearing with a bevel pinion j2 on a vertical shaft having a screw
thread on its upper end working in a nut on the bottom of the box a so raising it
as the sheets of paper are taken out and keeping the top sheet always at the
same level irrespective of the number of sheets remaining in the box.
k is a plunger working in guides having at its top a roller working in the
groove in the cam wheel fixed to the shaft f. The plunger & descends on
the middle of the strip of paper which has been drawn off the box a as above
described, carries it down into the slot in the table (Figures 7 to 9) folding
it against the two sides of the plunger and then forcing it between the guides m m
the guides m turning the ungummed edges of the paper against the edges of
the plunger and the guides m¹ turning the gummed edges of the paper onto the
ungummed edges. The further downward motion of the plunger carries the
now formed pocket between the endless bands n preferably of indiarubber or
like material working on rollers ni and supported by guides n². The plunger in
its downward movement carries the bands with it but when it returns the pawls n³
hold the rollers n¹ and bands n stationary and the friction of the latter retains the
pocket stripping it off the plunger. When the rollers n¹ are again turned by the
next descent of the plunger the pocket made as above described is delivered onto
an endless travelling felt o working on rollers o¹ o the upper one of which
carries a grooved pulley o² driven by a band 2 passes round guide pulleys p¹ to
a pulley 2 on the vertical shaft h¹.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:
1. Gumming the edges of the strip of paper by surfaces kept supplied with
gum and carried by oscillating levers substantially as described.
2. The gumming apparatus substantially as described and shown in the
drawings.
3. Removing the top sheet of paper from the box by a sucker substantially as
described.
4. The combination of a plunger with guides for folding the edges of the
paper substantially as described.
5. The combination of a plunger with bands pressing the edges of the paper
against it substantially as described.
G. The combination of the plunger, the guides and the endless band free to
move in one direction only substantially as described.
7. Apparatus for making pockets for cigarettes and the like substantially as
described and shown in the drawings.
