form of my device; and
Fig. 2O is a bottom plan view of the lid mem
ber of my modified form of device.
Referring now to the drawings of the preferred
form of device, my device comprises a casing 10
21 having closed ends 22 and 23 and closure lid
24. Lid 24 may be hinged to the upper wall of
the casing 2| so as to permit upward movement
of said lid.
Referring now to Figs. 6, ’7, and 8, my device 15
is provided with internal longitudinal extending
rollers 25, 26, and 21. Roller 25 is simply an
idling roller and is supported by av longitudinally
extending shaft whose opposite ends are received
in appropriate bearing apertures in end walls 22 20
and 23. Roller 26 is likewise supported by a
shaft whose opposite ends receive bearing support
inappropriate apertures in end walls 22 and 23
and a forming web 28, one of whose ends 29 is
anchored to said roller 26 by a clamping member
30. The roller 21 is supported by a longitudinally
extending shaft whose opposite ends are an
chored in appropriate bearing apertures in ends
22 and 23, and the opposite end 3| of web 28 is
clamped to said roller 21 by clamping member
30. Lid 24 is provided with a pair of vertically
depending ends 32 and 33, and these ends carry
30
bearing apertures in which a longitudinally ex
tending rod 34 has its opposite ends mounted.
The web 28 is passed from roller 21 upwardly to
and over rod 34 and downwardly to provide suf
iicient slack for the introduction of tobacco 35
as shown in Fig. 6. From the lowermost position
which the slack of web 28 assumes in Fig. 6 the
web is passed upwardly and over idling roller 25.
From the idling roller 25 the web is passed
through a reverse bend and clamped onto roller
26. Between the end wall 23 and the ends of the
shafts which support rollers 26 and 21 a friction
shoe 36 is interposed. The shoe 36 is of suñi
cient length to extend between the ends of the
above mentioned shafts and carries apertures
therein through which the reduced ends of said
shafts protrude. Intermediate the ends of said
shoe is provided an aperture through which an
attaching screw 31 is passed and anchored in a
threaded bore in the end wall 23. 'I‘he rollers
26 and 21 are of course keyed to their shafts by
appropriate pins and because of this feature ro
tate with said shafts. Adjusting screws 38 and 55.
2
2,133,698
39 pass through end wall 23 and impinge upon
the outer face of shoe 36 at points on said shoe
36 on opposite sides of screw 31. The screws 38
and 39 are of course received in appropriate
threaded bores in end wall 23 and when turned
inwardly force the opposite ends of shoe 36 to
ward opposite end wall 22. The ends of the
shoe then press upon the outer enlarged washers
40 and 4| on the shafts which support the rollers
. 26 and 21.
The frictional engagement caused by
this pressure retards any rotation of rollers 25
and’26 for a purpose later to be described. The
reduced ends of the shafts, which extend through
the ends of shoe 36, prevent the rotation of the
shoe on screw 31 as its axis.
A further means
of preventing rotation of the shoe 36 is provided
by the groove 53 in which shoe 36 seats. The
groove 53 serves the additional function of re
ducing the protrusion of the shoe from the inner
20 face of end wall 23.
The opposite ends of the shafts are provided
with protruding ends 42 and 43, and knurled
knobs 44 and 45 may be keyed by set screws
or otherwise to ends 42 and 43 respectively.
25
An appropriate threaded bore 46 is arranged
in end wall 23 for the reception of an adjusting
tool or screw driver 41 whose shaft is threaded
to cooperate with the threaded bore 46.
A
knurled head 48 of the screw driver 41 is turned
30 tightly so as to secure the screw driver in the
bore tightly. The screw driver is thus always at
hand when needed for making adjustments of
adjusting screws 38 and 39.
The upper face of housing 2| is provided with
a longitudinally extending aperture which is
covered by lid 24. The edge of the aperture
opposite the edge to which the lid 24 is hinged
is curved downwardly into a curved guide plate
49 for a purpose later to be described. Adjacent
the curved guide plate 49 the free end of lid
24 is curved upwardly as at 50 to provide a guid
ing surface and a protruding portion by which
the lid may be raised on its hinges. The end
walls 22 and 23 are secured in place by appro
priate screws which extend through the casing
material and into the end walls.
The operation of the device will hereinafter
be set out. In operation the lid 24 is raised and
preferably the web 28 is loosened by pushing
the same downwardly into the position shown
in Fig. 6. By doing so a U-shaped loop is formed
into which the tobacco 35 is placed. Downward
pressure on the bottom of the loop formation
will of course cause the web to be unrolled from
vrollers 26 and 2-1. After sufficient tobacco has
been placed in the loop the lid 24 is closed and
knob 45 is turned so as to rotate roller 21 in
the direction indicated by the arrow in Fig. 6.
By so doing the web 28 is rolled onto roller 21,
the guide rod 34 is then in the position indie
cated in dotted lines in Fig. 6, and as the bottom
of the U-shaped loop formation is- brought up
wardly the tobacco is rolled into cylindrical for
mation. In order to roll the tobacco more tight
ly after knob 45 has been turned as far as pos
sible the knob 44 may be turned in a clockwise
direction so as to rotate roller 26 in a clockwise
direction from the position indicated in Figs. 6
and 7. Such rotation of the knob 44 will roll
the web 28 onto roller 26 from roller 21. When
knob 44 has reached its limit of rotation the
knob 45 is again rotated in the directionY indi'
cated by the arrow in Fig. 6> so as to cause a
like rotation of the roller 21 until the web 28
76 .is wound upon roller 21. The tobacco` is then
in proper formation for the final step in the
cigarette making which is the application of the
paper to the cylindrical body of tobacco.
Referring now to Fig. 7 the lid 24 is raised
slightly as shown in this figure and a cigarette
paper 5| having a strip of mucilaginous mate
rial 52 on one long edge thereof is inserted be
tween the curved guide plate 49 and the end 50
of lid 24. By pushing the paper into this open
ing and laying the same on the tobacco it comes 10
in contact with the inside of web 28, and when
knob 44 and roller 26 are rotated in the direc
tion indicated by the arrow in Fig. 7 the inner
end of paper 5| is carried by the web 28 in a
cylindrical path and incases the tobacco 35
therein. When sufficient rotation has occurred
to bring the mucilaginous strip 52 close to the
curved guard plate 49, moisture may be applied
to said strip 52. The further rotation of the
roller 26 in the same direction will cause the
strip 52 to be drawn into the device and the
strip 52 will be sealed onto the now cylindrically
formed ‘paper incasing the tobacco. After this
has occurred the lid may be raised to the posi
tion shown in Fig. 8 and the guide rod 34 will
raise the web 28 upwardly so as to carry the
completed cigarette into the position shown in
this figure.
If the device is not rolling the cigarettes
tightly enough the screw driver 41 may be used
to tighten screws 38 and 39. The inward pres
sure of screws 38 and 39 will cause the shoe 36
to be pressed tightly against the washers 48 and
4| on the roller supporting shafts. This inward
pressure will frictionally resist the rotation of
said shafts by knobs 44 and 45 and the tobacco
35 will be drawn into a smaller and more com
pactly formed cylinder than would be the case
if there were no friction on the washers 40 and
4|. It may be necessary to replace web 26 oc
casionally with a new one, and this may be easily
accomplished by removing end wall 22 or 23.
The clamps 30 may then be removed from the
web 28, a new one placed on rollers 26 and 21,
and the clamps 30 replaced. After the end wall
is replaced the device will be in condition for
further operation,
A modified form of my device is shown in Figs.
11-20, inclusive, and will now be described. The
device comprises mainly a casing 55 having end
walls 56 and 51. A lid 58 is hinged to casing 55
and is adapted to cover an opening in the upper
face of said casing.
A rotatably mounted idling roller 59 is sup
ported by a shaft whose opposite ends are re
ceived in appropriate bearings in end walls 56
and 51. The roller 59 is positioned adjacent the
opening in the upper face of casing 55 and also
adjacent the upper horizontal wall of said cas
ing. The lid 58 is provided with a pair of de
pending ears 60 on opposite ends thereof which
carry bearing apertures for opposite ends of a.
shaft which supports roller 6|. The roller 6|
is covered with a coating of resilient material
such as rubber sheeting so as to provide a cush~
ion and friction surface. When the lid 58 is in
closed position rollers 59 and 6| are in close
proximity so that there is only a small amount
of space between their peripheries. Notches 62
and 63 are arranged in the upper edges of end 70
walls 56 and 51 for the purpose of receiving the
opposite ends of roller 6| when the lid 58 is
brought to closed position.
'I'he end walls 56 and 51 are each provided
with a. pair of spaced bearing apertures in which-
2,133,698
the opposite ends of roller shafts 64 are received.
These shafts are arranged in substantially the
same horizontal plane and are arranged adjacent
the bottoms of end walls 56 and 51. Because of
the positioning of rollers 64, rollers 59 and 6I
are arranged between but above said rollers 64.
A drive roller 65 is supported on a longitudinally
extending shaft whose ends receive bearing sup
port in apertures in end walls 56 and 51, and the
10 surface of roller 65 is covered with a strip of
resilient, soft, anti-slip rubber 66 for a purpose
to be later described. Roller 65 is peferably sup
ported at a point intermediate the upper wall and
lower wall of casing 55. An endless web or belt
61 is arranged to pass around and roll upon each
of the rollers 59, 6I, 64, and 65. A pressure
shoe 68 is provided with an internal semi-cylin~
drical pressure surface and adapted to press the
web 61 against the rubber covering 66 of roller
65. A stud 69 being elongated in cross-section,
is adapted to protrude through a similarly shaped
aperture in casing 55 and because of the elongated
cross-sectional shape prevents the rotation of stud
59 relative to the casing 55. A leaf spring 18
is provided with a central opening similar in shape
to the cross-sectional outline of stud 69 and the
spring 1G is interposed between the outer con
7
Vex surface of pressure shoe 68 and the wall of
casing 55. A knurled knob 1I may be keyed by
a set screw to the shaft which supports actuating
roller 65 and the rotation of knob 1| causes the
rotation of roller 65.
As before stated the upper face of casing 55
is provided with a longitudinally extending open
ingwhich is covered by lid 58 when said lid is in
closed position. The lid 58 is hinged to one edge
of this opening and the opposite edge of the cas
ing is turned and curved downwardly to form a
guard lip 12 whose function will be described.
40 The free edge of lid 58 is curved upwardly as at
13 and serves as a guide lip and also as a lifting
lip.

The operation of the modified form of my device
is as follows: The lid 58 is lifted until the parts
of the device assume the position shown in Fig. 15.
Tobacco 14 is then inserted in the upwardly
opening U-shaped loop of web 61 in a desired
quantity. The lid 58 is then closed to the posi
tion indicated in dotted lines in the same ñgure
and at this time inward pressure is applied to
the outer end of stud 69 if the spring 10 does not
cause gripping. Such pressure causes the web 6l
to be clamped between the inner pressure sur
face of shoe 68 and the Outer anti-slip surface
of roller 65, and when knob 1I is rotated in the
direction indicated by the arrow in Fig. l5 the
tobacco 14 is brought into a cylindrical forma
tion. The pressure shoe 68 prevents any slip
ping of the web 61 on roller 65 and thus causes
the open U-shaped loop of web 61 in Fig. 15 to
be made smaller as shown in Fig. 16 and causes
said web to grip the cylinder of tobacco tightly
in this position. The rollers 59 and 6l are
spaced apart a very slight distance and barely
65 permit a double thickness of web 61 to be inter
posed between said rollers. Referring now to
Fig. 16 after the tobacco is formed into a cylin
drical shape by the rotation of knob 1I the lid
58 is raised slightly by the curved end 13 and a
70 paper wrapper 15 is inserted into the interior of
casing 55 and into the position shown in Fig. 16.
While stud 69 is still depressed further rotation
of knob 1| in the direction indicated by the
arrow will cause paper 15 to be carried by web 61
75 around the cylindrically packed tobacco and when
3
the end 16 of paper 15 is brought to a position
adjacent the guard plate 12 it should be mois
tened so that the mucilage thereon will cause the
end 16 to adhere to the outer surface of the cy
lindrically formed paper. Further rotation of 51%
knob 1I will cause the end 16 to be carried into
the casing and sealed onto the outer surface of
paper 15. After the sealing operation the ciga
rette is completed and when lid 58 is raised the
cigarette will be carried into the position shown 10i
in Fig. 18.
From the foregoing description it can be seen
that I have provided a device in which the ciga
rette may be made with the tobacco tightly packed
for the full extent of the length of the cigarette 15
paper. This is quite an improvement over the
ordinary portable cigarette forming device in
which it is necessary to clip the ends because of
the failure of the device to pack the tobacco
tightly throughout the length of the cigarette. 20:?
My device accomplishes my new result because
of the fact that the web 28 is of greater width be
tween the ends than it is adjacent the points at
which the web 28 is attached to the rollers 26
and 21 in my preferred form. This fact can be 25>
clearly seen in Fig. '1. By varying the width of
the web 28 and having it wider at its center than
at its ends the longitudinal edges of the web are
in close proximity to the end walls 22 and 23 at
the location where the tobacco is inserted in the 30!
device. Since the extreme end portions of the
web do not come in contact with the tobacco at
any time it is not important that these ends are
of less width than the center of the web and the
center width is sufficiently great to cause the 35':
packing _of the tobacco at the extreme ends of
the cigarettes. The ends of the web 28 are made
of less width so that the longitudinal edges of
the ends will not be damaged by contact with the
washers 4D or 4l. My modified form of construc- 4b’
tion may have a web having a uniform width
through its entire extent and because of this fact
and the close proximity of the longitudinal edges
of the web to the inner faces of the end walls the
extreme end portions of the cigarettes will be 45:
tightly packed.
In addition to the other advantages above
pointed out it is possible with my device to manu
facture cigarettes which may vary in cross
sectional dimension from one-eighth to one-half
inch by the simple procedure of varying the
amount of tobacco used.
In order to secure a
more tightly packed cigarette the adjusting
screws heretofore described in connection with
my preferred form may be tightened. The final 55.
step of embracing the cylindrical body of tobacco
with the cigarette paper is accomplished in a
very simple manner and does not depend upon
pushing the paper any considerable distance into
the device. After the paper is laid upon the 60
tobacco further slight movement of the web
causes the paper to be carried into the device
and around the tobacco. When the muci
laginously treated edge of the cigarette paper
approaches curved lip 58 of the preferred form 65
or curved lip 13 of the modified form moisture
may be applied to the mucilaginous strip while
the strip receives support from either of the
curved lips mentioned. The final sealing' opera
tion is accomplished in such a manner that due 7015
to the guard lips 49 and 12 employed in both
forms of construction there is no possibility that
the mucilaginous material from the paper will
be deposited upon the webs.
While my invention accomplishes all the ad- 75
4
2,133,698
vantages set out it may be economically manu
factured and is extremely easy to operate.
While I have shown and described my
preferred form of construction I do not wish to
be limited to the details of said preferred form
of construction or the modified form of con
struction shown herein, but wish to avail myself
of all variations coming within the scope of the
