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 to provide a machine by means of which cigarette
papers, printed with trade marks or other signs and made up in the form of tubes
and arranged for packing for transport may be produced from a roll of suitable
paper, and the invention consists in improved machinery for printing the paper, for
making same into tubes and for arranging the tubes so formed for packing for
transport.
In the accompanying drawings
Fig. 1 is a side elevation of the machine embodying the improved mechanism for.
printing, making and packing.
Fig. 2 is a plan view thereof.
Fig. 3 is a section on line 7. 8. of Fig. 2.
Fig. 4 is a section on line 1. 2 of Fig. 1 and Fig. 5 is a section on line 3, 4 of
Fig. 1 showing the paper moving mechanism and the main driving shaft with gear
connected therewith.
Figs. 6 to 9 are detail views of the printing machinery.
Figs. 10 and 11 detail views of the cutters for cutting the tubes from the main
tube as is formed.
Figs. 12 to 21 are detail views of the mechanism by which the strip of paper is
formed into a tube.
The machinery is arranged upon a bed-plate A and consists of the paper-feed B
the printing machinery C, the feed rollers D, the tube forming mechanism E, the
packer F and the main driving shaft G with gear for operating the various
parts.
The paper feed B is shown in Figs. 1 and 2. and consists of the frame a supporting
in bearings the drum a on which the roll of paper a¹ is fixed. The brake as is
pressed, by the spring a with set screw adjustment, against the periphery of the
drum to retard its movement and keep the paper taut as it passes over the
rollers a³ a as a to the printing machinery which is preferably placed next in
order to print the required sign on the paper previously to its being made into
a tube this printing taking place during the stoppage of the movement of the
paper during which the length of finished tube is cut off by the shears. The
printing is performed in two operations, by the press C¹ which imprints in size
and the gold apparatus C by which the gold or other powder is applied to the
paper to adhere to the impression in size, the superfluous powder being brushed
off by the brush d.
The press C is driven from the main shaft G by the lateral-throw curve
disc and the excentric b³. The disc rocks the shaft by the arm 63 and
moves the printing rollers 67 68 69 by means of the lever arm 65 and connecting
rod over the frame 610 and draws them back again. By this means the size
or equivalent liquid is carried from the holder 612, whence it is delivered by a
roller operated by a crank arm and rod 614, and is delivered onto the table
arm of the
rotated by toothed gear 618 moved by rod 67 attached to an
lever arm 65, and in due course transferred to the type 1 in the head 63 of
the press which is moved by the lever 621 pivoted at 620 and moved by the
excentric 6 on the main shaft G.

page_text: The paper strip passing under the plate or bed e¹ is thus printed with the
liquid intended to receive and retain the gold powder or other powder used for
the printing which is delivered by the apparatus C². This apparatus comprises
the plate or pad c¹ set in the head of the pressing rod e¹ which is moved by the
lever aforesaid. The rod c is not in direct attachment with the lever 21
but rests in a bracket secured thereto and slides in a sleeve movable in guide-
ways to bring the plate c¹ alternately under the powder box c³ and the plate e',
this action being performed by the lever arm c³ on the rocking shaft and the
rods e, cand lever c (Fig. 7). At the moment when the plate c¹ is under
the powder box ² the hammer is caused by the lever 8 moved by the can c
on the shaft G, to strike the box c so that some of the powder is caused to fall
through the perforated floor of said box onto the plate c which is thus charged
with powder preparatory to be moved back under the plate e¹ and raised to
transfer the powder to the paper strip under the said plate e¹. The rocking
plate may serve as a floor closing the box c² when the plate c' is not there-
under. The plates 61 and c and the powder box c are movable or adjustable
in the line of the direction of movement of the paper strip to provide for adjust-
ment of the printing according to the length of the tubes to be manufactured.
The paper strip thus printed passes over the brush d by which the superfluous
powder is removed and thence to the feed rollers D shown in Figs. 1. 2 and 5.
The rollers ff are driven by the toothed wheels 212 from the shaft g which
is driven with an intermittent rotation from the main shaft G by the excentric g¹
and shifting gearing g³ ³. The paper is thus drawn with an intermittent
movement and passes to the tube forming mechanism E shown in Figs. 1, 2
and 12 to 20 where it is folded or curved and the edges connected to form a
tube.
The spindle his supported in the holder h¹ the shank h" of which is carried
by the block on the bed plate A. and may be adjusted at the required
height therein. The spindle is slung therein by the leaf plate h² and is held
with the wheel on the outer end pressed against the wheel by the screw *
in the arm bearing on the end of the spindle (Fig. 12). To the block 5 on
the spindle is pivoted the spring or leaf h resting on the block 4 and pressed
down by the screw h. The pin ' taking into a slot holds the spring he against
lateral movement. The end of the spring carries the folder 40 which is cut out
on the under side as in Fig. 20. The spindle carries also the slit sleeve ¹³
with a flaring end. The paper a Fig. 12 fed by the roller feed D is curved
into a shape to pass through the block as in Fig. 15 and continues in
this form past the blocks 6 h (Figs. 16 and 17 until the upper edges are
drawn together to pass into the slit in the sleeve h¹³ (Fig. 18) where they are
further drawn together (Fig. 19) until they enter in contact into the hole in
the folder h (Fig. 20) from which they issue folded together as in Fig. 21 to
be pressed together by the wheels which are preferably milled wheels. The
wheel is driven by chain and toothed gear and shaft, at the same
circumferential speed as the feed roller system D and with the same intermittent
movement. This movement is regulated by the micrometer screw adjustment g
in the rod and the length of each cigarette tube is according to this
adjustment.
The length of finished tube is cut off from the paper by the cutters k (Figs. 10
and 11) being shears closed by spring 4 and opened by the levers k² k* and
cam disc from the main shaft Ğ.
The cut off tube passes through the receiver m into the packing apparatus
shown in Figs. 1. 2. 3 and 4. This consists prin ipally of a slide 1 moved in
prismatic guides by the main shaft G through the side-throw cam disc 18
arm shaft 10, crank arm 7 and rod 12. The slide carries the finished paper
tube through a slot 13 into the box 12 resting on the rails 11. The apparatus
further comprises the rake which is supported by the rod raised and lowered
by the movement of the main shaft G by means of the cam disc 1¹³ and lever 1¹

page_text: pivoted at (Fig. 1). This movement of the rake allows the tubes to pass
freely along the rails or ledges when the rake is lowered but holds the tubes
parallel to each other when on raising the rake the divisions or partitions
thereon rise between the tubes. The latter are thus kept parallel to each other
and ready for packing in convenient boxes or otherwise.
The parts operate in the following sequence or cycle. The paper being
carried through the machine, the shaft G is turned. During the first half
revolution of the shaft, the printing type is lowered and inked, the powder pad
is lowered and provided with a charge of powder. The brush brushes the paper
moving over it and removes the superfluous powder from the previous printing.
The roller feed D moves the paper and the spindle and devices form the same
into a tube and push the latter forward between the previously opened blades
of the cutters and into the receiver m while the previously cut off tube is carried
into the packer. During the second half of the revolution of the shaft G the
feeding devices remain stationary and the paper also. The printing type makes
the adhesive impression, the powder pad presses the gold or other powder onto
the impression made during the previous revolution, the cutters sever the length
of finished tube, the slide 1' returns and the rack l³ is raised.
Thus for each revolution of the shaft G a paper tube is delivered into the
packer by applying a counter to the shaft G, the number of tubes may be
ascertained or regulated.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is;
