PROVISIONAL SPECIFICATION.
Improvements in Machines for Forming and Attaching Mouth Pieces
to Cigarettes.
I, EDWARD THOMAS POLLARD, of 4 & 5, Gough Square, Fleet Street, London,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to. an improved form of device designed to be used in
conjunction with the machine illustrated and described by me in the specification
forming part of the Application No. 11617 of 1898 and in which specification is
shewn a device for attaching mouthpieces to cigarettes by causing the said mouth-
piece, when completed, to abut against the end of the cigarette to which it is
then secured by means of a gummed strip of suitable paper. Now it is the object
of the present invention to attach the mouthpiece to the cigarette by partly in-
serting the same within the cigarette paper, at one end of the cigarette, a space
being formed to receive it by causing the tobacco to be pushed out at one end
a short distance, the tobacco thus expelled being cut off by suitable shears or
other like device forming part of and operated by the machine.
In carrying the invention into effect the cigarette is allowed to fall from the
hopper between 3 or more rollers covered with rubber and with all their
peripheries at the point of contact with the cigarette moving in the same direc-
tion. Whilst the cigarette is thus held and rotated, a mandrel of approximately
the same diameter as the inside of the cigarette is caused to advance, the end
coming into contact with the end of the cigarette, the rotation and compression
of which between the rollers aforesaid has loosened the tobacco so that it is
pushed forward, leaving a space at one end in which the mouthpiece, (formed of
cardboard or other suitable material) is afterwards inserted.
The cigarette on being released from the rollers aforesaid is allowed to fall
into a suitable holding device by which it is retained whilst the mouthpiece is
inserted and the protruding tobacco is cut by a suitable device operated by the
machine. The mouthpiece is formed upon a mandrel in the same manner as
described in my prior application 'above referred to and is retained in position.
at the end of the cigarette by the expansion of the material of which it is formed.
When the mouthpiece has been inserted, the cigarette is allowed to fall into a
suitable hopper provided to receive it.
Dated this 1st day of September 1898.

page_text: 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:--
This invention relates to an improved form of device designed to be used upon
the machine described and illustrated in the specification forming part of the
application No. 11617/98, and in which specification is shown and described a
device for attaching mouthpieces to cigarettes by causing the said mouthpiece,
when completed, to abut against the end of the cigarette to which it is then
attached by means of a gummed strip of paper. Now it is the object of the
présent invention to attach the mouthpiece by wholly inserting the same within
the cigarette paper at one end thereof, in which it is retained by the natural
resiliency of the material forming the mouthpiece, a space being formed to receive
it by causing the tobacco to be pushed out from its envelope a sufficient distance
to accommodate the mouthpiece, the tobacco thus expelled being cut off by means
of a suitable cutting device.
In carrying the present improvements into practice I employ substantially the
same parts and arrange them in a similar manner as in the preceding case referred
to above, but with this difference, that as I no longer require the gummed paper
I am able to dispense therewith and the whole of the feeding, gumming, and
cutting mechanism for the same, and in lieu thereof I employ an arrangement of
parts whereby whilst the cigarette is being rolled, a mandrel is caused to bear
against one end of the tobacco, and as the said tobacco under the rolling action
becomes loosened within its envelope to push it bodily forward a short distance,
causing it to extend at one end beyond its outer paper wrapper, leaving a space
at the other, into which the mouthpiece is inserted. When this operation has
been completed, the cigarette is allowed to fall from between the rollers into a
tray or trough, so arranged that the cigarette when laying therein is in a line
with the mouthpiece forming mechanism, which is substantially the same both
in action and construction as the mechanism of my former machine, the mouth-
piece, however, in this case being pushed out through a tube which is inserted
in the end of the cigarette by pushing the same thereon by means of a mandrel
which comes into action and bears against the opposite end of the cigarette.
When in position with the paper upon the tube aforesaid a clutch comes into
action and bearing upon the paper upon the tube holds the same whilst the mouth-
piece is pushed through the tube and coming into contact with the tobacco pushes
the cigarette forward, the mandrel aforesaid being withdrawn to allow of its
being pushed clear of the tube. The protruding tobacco may now be cut off
either by a knife or shear forming part of and acting in conjunction with the
machine, or it may be afterwards cut by hand.

Referring to the drawings a b c d are four rollers covered with rubber or the.
like between which the cigarette falls from the hopper (not shown), two of which

page_text: -
are carried by the frame e which is secured by screws or the like f to the vertical
bracket or support g. Pivotally attached to the frame e is a second frame h,
the side members of which support the spindles of the rollers c d. This latter
frame has at one end an arm or extension provided at its end with a roller i held
in contact with the cam j, secured to the main shaft & by means of the spring/
attached to the end of the arm m cast upon or attached in any suitable manner
to the frame h, the rollers under the action of this cam being first caused to
open sufficiently to receive the cigarette from the hopper, and then upon the
completion of its rolling to open and allow it to fall therefrom.
Formed upon the frame e is a bearing for a short spindle a upon the inner
end of which is mounted a small pinion o with which engage similar
pinions a, b, c, d, mounted respectively upon the spindles of the rollers a b c d
At the outer end of the spindle n is a small sheave actuated from the main
shaft by the larger slicave q, a band or belt transmitting motion from one to
the other by means of a suitable cord or band.
At the opposite end of the frame e is a guider for a mandrels, the mandrel
being at its outer end supported by a guide s', secured in any suitable manner
to the end bracket of the shaft . This mandrel is actuated in its forward
motion by the spiral springs, which encircles the mandrel and is compressed
between the collar s³, upon the rod and the face of the guide aforesaid. The
spring is compressed by means of the plate forked at its outer end to straddle
the mandrels and attached to the block u', forming part of the mouthpiece
forming mechanism. It will be seen from the foregoing that upon the forward
motion of the block w, the mandrel will, under the influence of the spring ³,
be pushed forward until it abuts against the end of the cigarette being rolled
between the rollers aforesaid, and its diameter being smaller than that of the
cigarette as the tobacco becomes loosened under the rolling, the spring advancing
the rod pushes the tobacco forward bodily causing a certain portion to extrude
from the end of the paper wrapper as indicated in Figs. 9 and 10.
Upon the
return motion of the block w, the plate w will be brought into contact with
the collar 3, and push the mandrel back clear of the cigarette. Located beneath the
rollers a b c d is a suitable tray or trough supported either by the side pieces
of the frame e or in any other convenient manner, into which the cigarette falls
upon the completion of the last described operation, the cigarette when theroin
being in line with the mouthpiece which is at one end, and with the rod w at
its other end. As the construction of both these devices is precisely the same
as in the aforementioned patent it is only necessary to describe the action thereof
with regard to the attachment of the mouthpiece. At the end of the guide from
which the mouthpiece is discharged from the forming mechanism is attached a
short piece of tube a slightly tapered towards the outer end and of a size slightly
under that of the cigarette, so that upon the advancement of the rod w the
cigarette will be pushed along and the tube caused to enter the space at the
end thereof from which the tobacco has been removed. When the rod has
completed its forward stroke a clamp actuated from any convenient part of the
machine comes into action and holds the cigarette upon the tube . the clamp
being released to allow of the cigarette being pushed off the tube when the
mouthpiece comes into contact with the tobacco as shown in Fig. 4.
cigarette is pushed forward the rod w is withdrawn and the cigarette is eventually
free to be ejected from the trough, which may be accomplished in any convenient
manner, the end being trimmed either by suitable shears which may form part of
the machine or they may be cut by hand in the usual manner employed when
making "hand made" cigarettes.
As the
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what.
I claim is:

page_text: the tobacco by means of rollers so that the same may be pushed-forward to allow
of the introduction of the said mouthpiece.
2. In a machine for forming and attaching mouthpieces to cigarettes, the
combination of a number of revolving rollers with a mandrel adapted to bear
against the end of the cigarette, whilst the same is being rolled, and push the
tobacco forward in its envelope of paper to form a space for the insertion therein
of the mouthpiece, substantially as described and shown by the accompanying
drawings.
'
3. In a machine for forming and attaching mouthpieces to cigarettes, the
combination of a device for loosening and pushing forward the tobacco in its
envelope with a device for forming the mouthpiece and holding the cigarette
whilst the said mouthpiece is attached, substantially as herein described and
illustrated by the appended drawings!
4. The improvements in machines for forming and attaching mouthpieces to
cigarettes whereby the tobacco is first loosened in its envelope of paper, then
pushed forward aud the mouthpiece inserted in the space at the end, and finally
trimmed, all substantially as herein described and illustrated by the accompanying
drawings.
