I, GEORGE FREDerick Limmer, of 82, Mark Lane, in the City and County of
London, Consulting Engineer, do hereby declare the nature of this invention to
be as follows:-
This invention relates to cigarette machines of the type in which the tobacco
is compressed in a suitable chamber and afterwards pushed into the paper tube
by means of a suitable transporter and the object of this invention is to enable
the tobacco to be placed in the paper tube without waste or damage. Now accord-
ing to this invention instead of the transporter or bayonet sometimes used which
only engages with the tobacco to be placed in the paper tube on one side of the
plug I provide a suitable gripper or forceps which grips the plug of tobacco to
be placed in the tube on opposite sides of the diameter thereof and so prevents
spreading of the tobacco forming the plug. One portion of the gripper or forceps
is secured to or forms part of a rod or tube which is hinged to a second rod or tube
to which the other portion of the gripper or forceps is hinged in such a manner
as to compel the portions of the forceps or gripper which hold the compressed
tobacco or plug to remain parallel to each other while transporting the tobacco
plug from the compressing chamber to the paper tube.
I provide also a suitable spring by means of which the said portions of the
gripper or forceps are opened when the sliding block forming one portion of the
compressing chamber is withdrawn to allow a fresh charge of tobacco to be placed
therein.
I provide further a spring or other suitable device by means of which the
portion of the gripper which is hinged to its rod or tube is normally pressed
against one portion of the compressing chamber preferably against the movable
portion thereof.
I attach the usual handle or other device to the hinge of the gripper rods or
tubes preferably by means of the hinge pin. When the compressing chamber is
open the two portions of the gripper or forceps which hold the tobacco plug are
in contact with the vertical sides of the said chamber and when the said chamber
is closed the said portions of the gripper or forceps close on to the tobacco plug
and by the movement of the said handle or other suitable device place the said
plug in the paper tube the friction between the tobacco and tube when the former
is fully inserted in the tube allows the gripper to be withdrawn without displacing
the tobacco in the tube.

page_text: Improvements in and connected with Machines for Filling Paper
Cigarette Tubes with Tobacco.
I, GEORGE FREDERICK LIMMER, of 82, Mark Lane, in the City of London,
Consulting Engineer, 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:—
This invention relates to cigarette machines of the type in which the tobacco
is compressed in a suitable chamber and afterwards conveyed into the paper tube
by means of a suitable transporter and the object of this invention is to enable
the tobacco to be placed in the paper tube without waste or damage and without
any ramming action.
Now according to this invention instead of the transporter or bayonet sometimes
used which only engages with the tobacco to be placed in the paper tube on one
side of and at the end of the plug I provide a suitable gripper or forceps the
jaws of which grip the plug of tobacco to be placed in the tube on opposite sides
of the diameter thereof and so prevents spreading of the tobacco forming the plug
and avoids ramming.
One portion of the gripper or forceps may be secured to or form part of a rod
or tube which is hinged to a second rod or tube to which the other portion of the
gripper or forceps may be hinged in such a manner as to compel the portions of
the forceps or gripper which hold the compressed tobacco or plug to remain
parallel to each other while transporting the tobacco plug from the compressing
chamber to the paper tube.
I provide also a suitable spring by means of which the said portions of the
gripper or forceps are opened when the sliding block forming one portion of the
compressing chamber is withdrawn to allow a fresh charge of tobacco to be placed
therein.
I provide further a spring or other suitable device by means of which the
portion of the gripper which is hinged to its rod or tube is normally pressed
against one portion of the compressing chamber preferably against the movable
portion thereof.
or
I attach the usual handle or other device to the hinge of the gripper rods 8
tubes preferably by means of the hinge pin.
When the compressing chamber is open the two portions of the gripper or
forceps which hold the tobacco plug are in contact with the vertical sides of the
said chamber and when the same is closed the said portions of the gripper or
forceps close on the tobacco plug and by the movement of the said handle or other 3
suitable device place the said plug in the paper tube the friction between the
tobacco and tube when the former is fully inserted in the tube allows the gripper
to be withdrawn without displacing the tobacco in the tube.
And in order that my said invention may be fully understood I will proceed to
explain the same with reference to the accompanying drawings in which:-
Fig. 1, represents a section through the compressing chamber when open.
Fig. 2 represents same closed.
Fig. 3 is plan of gripper or forceps removed from the machine.
Fig. 4 is elevation of same.

Fig. 5 is section through compressing chamber shewing nozzle.
The same letters denote the same parts in all the figs.
a is the fixed die forming the front and bottom of the compressing chamber
b is the moving die forming the back of the compressing chamber
41

page_text: c is the cutter which forms to top of the compressing chamber and removes any
superfluous tobacco from the chamber.
df are the two jaws of the gripper which lie in recesses formed in the dies a
and 6 respectively.
Each portion of the gripper is formed of a piece of metal or other suitable
material that part thereof which holds and conveys the tobacco plug into the
paper tube being an arc of a circle in section as shewn by Figs. and 2 or the
jaws may be of any other suitable shape to suit the form of cigarette to be made
oval or elliptical for example.
The portion d is formed in one with or attached to the sliding block
moves in the usual guide in the frame of the machine.
which
The said sliding block is slotted horizontally to receive the link h which is
hinged to the said block at i and to the other portion f of the gripper at j. A
spring secured to the link h serves to separate the two portions of the gripper
when the compressing chamber is opened and also to compel the portion f to
remain parallel to the moving die b.
The pin is long enough to engage with the slot in the usual handle by means
of which the grippers are moved into and removed from the paper tube.
As will be seen on inspection of the drawings the jaws of the gripper or forceps
are long enough to hold the tobacco plug without the end of the said plug resting
on the solid portion thereof by which means all ramming of the plug into the
tube is avoided as the said plug is simply gripped circumferentially and placed
in the tube without any end pressure on the plug.
The friction between the paper tube and and the top and bottom of the plug
enables the gripper or forceps to be withdrawn from the tube without displace-
ment of the plug therein.
In some cases as for instance when using wet tobacco it may be necessary to
ensure efficient working of the apparatus to withdraw or partially withdraw one
portion of the gripper from the filled tube before the other which may be effected
by prolonging the portion f beyond the hinge and forming a slot in the said
prolongation as shewn by dotted lines Fig. or I may use any other suitable
mechanical means to prevent the plug from being drawn out of the paper tube
along with the grippers. For example I may use 3. light springs which is
pressed down into a recess in the bottom of the nozzle n when the tobacco plug
is being placed in the paper tube and which spring rises when the plug has
passed over it enters the space between the grippers behind the plug and prevents
the withdrawal thereof from the tube when the grippers are retracted into the
compressing chamber.
The parts of the machine shewn in the drawings are somewhat larger than
full size for the sake of clearness it being understood that the jaws of the gripper
or forceps which enter the paper tube are as thin as possible consistent with
strength.
Forceps or grippers constructed according to this invention are applicable to
rotary machines as well as to the reciprocating machines usually employed.
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:
1. In machines for filling paper cigarette tubes with tobacco the combination
with the usual compressing chamber and levers of a gripper or forceps having
concave or other suitably shaped jaws which jaws take hold of the compressed
tobacco plug and place it in the paper tube without any end pressure or ramming
action on the plug all substantially as herein before specified.
2. In machines for filling paper cigarette tubes with tobacco the gripper or
forceps formed in two portions df provided with concave or other suitably shaped
jaws, the portion d being formed in one with or secured to the sliding block g and
the portion f hinged to a link h which link is also hinged to the block g by the

page_text: pin which pin engages with the usual lever handle for operating the mechanism
which conveys the tobacco plug from the compressing chamber to the paper tube.
3. The improvements in machines for filling paper cigarette tubes with tobacco
herein before specified and shewn by the accompanying drawings.
