This invention relates to the art of m'inting,and has for an important object thereof the
provision of means and an improved method for
impressing bronze characters or designs on paper
the sheet Z is trained over an idling roller II
and then passed» over a drum IU which is rotat
ably `carried by a shaft 3|. The shaft 3| is
mounted on one end of a rock arm 32 pivoted as’
at 33. A driven gear 28 mounted on a shaft 9 5'
5- used in the production of cigarettes.
‘
Another object of this invention is to provide a y is disposed adjacent the drum I0, and this shaft
means whereby bronze or like powder may be
applied to a paper strip or sheet in a manner
whereby the 'color material will adhere to the
paper in an even manner and will not readily
wipe oiî on`account of handling of the paper.
p A further object of this invention is to provide
a method and means for applying a powder color
to a paper in a manner whereby the color will
15 be maintained on the paper so that the subse
quent movement of the printed paper through a
cigarette machine will not eiîect a clogging yof
the machine by reason of the powder color used
in impressing the character or object >on the
2@ paper being vwiped or otherwise removed from
'the
paper;

This printing cylinder or member 8 l ì
has a suitable printing surface carrying the de
sir`ed indicia, design or character which may be 10
impressed upon the surface of the sheet Z.
A second printing cylinder Il which is mounted
on a shaft I8 is mounted in a position for en

A driving gear 25 is mounted on a shaft 24
and may be connected to a'suitable source of 20
power supply. A gear 26 is mounted on a shaft
I8 and meshes with the gear 25, and a driven
gear 28 is mounted on the shaft 9. Rotation of
the gear 28 is effected through a gear 2l which
meshes with‘the gear 23 and the gear 28.

Figure 3 is a fragmentary plan view of the

Referring to the drawings, the letter Z desig
40 nates a sheety of paper or like flexible material,
and in the present instance the paper Z is of a
character similar to that used vin the produc
tion Xof cigarettes. Heretofore attempts have
been made to print or otherwise impress letters,
45 characters or designs upon a sheet or strip of
paper, but as this must be'done prior to the
rolling of the `cigarettes, the -powdered color
which is' in a dry _state when applied will not
satisfactorily adhere to the paper, and the rub
50 bing ofi of the powder seriously affects the oper
ation of the cigarette machine.
At the same
time, when the cigarette is finally completed the
indicia, design or the like is damaged.

is mounted on a rock arm 3 and is adapted to
contact at timed intervals with the supply drum 35

«
`
TheY ~ cementitious material on the transfer
roller or drum i is transferred to a grinding
roller or drum 5 which is mountedon a bracket

40
The cementitious material on the transfer
member 5 is smoothed by a counter-rolleror
drum 6 also carried by the bracket 36 and the
periphery of _which contacts with’the drum 5.
A transfer roller ‘l is also carried by the bracket 45
36 in spaced relation to the counter-roller 6 and
is disposed in the path of the movement of the
printing cylinder or member 8. Adjustment of '
the bracket arm 36 may be had by means of a '
thumb screw 3l so that the proper contact of 50
the transfer roller 'l may be had with the iin
pression cylinder 8.
In -the present instance the reservoir contains

I1. By reason of the larger impression made by
the cylinder 8 any slight excess of powder car
' ried by the printing cylinder I1 will adhere to
the sheet Z, and this larger base impression wid
permit slight variance in the positioning of the
impressions, so that if the impressions are slightly

retained on the sheet Z and not permitted to drop
off or be rubbed off during the movement of the

It is obvious that various changes and modifi

Adjustment of the rock arm 32 is effected by caily tensioning said supporting means to bias 25

means of an adjusting screw 35 which engages the said rollers against the cylinders, means for
the arm 32 adjacent the end opposite from the placing a mucilaglnous substance on the base
shaft 3|, and a spring 34 holds .the end of the cylinder for impression on the sheet,l and means
contacting with the color cylinder for placing a
arm 32 in contact with the screw 35. In like
30 manner the rock arm I4 is adjusted by means of
an adjusting screw I6 which engages the arm I4
at the end opposite from the shaft I3, and a
spring 30 maintains the arm I4 in contact `with
the adjusting screw I6.

'
In accordance with the method and means
hereinbefore described, the mucilage or cementi
tious material is first applied to the face of the
sheet Z, and the impression made by the base
printing cylinder 8 is slightly larger than the
impression made by the color printing cylinder I1.
40
When the driving gear 24 is rotated a rotation
of the gear 26 is effected, and likewise rotation of
the gear 28 -through the gear 21. ’ Preferably the
45
gears 26, 21 and 28 are of the same size so that
the cylinder 8 will rotate at the same speed as the
cylinder I1.
«
'
As the printing surface of the cylinder 8 con
tacts with the transfer cylinder or roller 1 a
transfer of the mucilage or cementitious material
is effected, and when the printing surface of the
50 cylinder 8 contacts with the surface of the sheet
Z» the impression in mucilage or cementitious
material will be made. While this cementitious
material is still soft the color cylinder I1 will
impress the colored powder upon the surface of
55 the mucilage or cementitious material. Prefer
ably-,the transfer'drum or roller 20 is rotated
through the medium of a gear I9> mounted on
the shaft I8` which meshes with a gear 22 mounted
on vthe shaft 2l, and the ratio of the gears I9
and 22 is such that the linear movement of the
powdered color thereon, said color cylinder be 30
ing ‘so timed with respect to said base cylinder
‘whereby the powdered color on the color cylin
der will be impressed on the mucilaginous impres
sion.
2. A means for placing powdered color im 35
pressions on a web comprising a base printing
cylinder, a color printing cylinder, means for
rotating the cylinders in unison, a pair of im
pression rollers disposed one adjacent each cyl
inder, a. lever support for each of said rollers '40
pivoted to support the roller swingably, a spring -
attached to each of said levers biassing it to swing
to place an impression roller against a cylinder,
said rollers having the web trained thereover,
means for placing a mucilaginous substance on 45
the base cylinder for impression on the web, and
means contacting with the color cylinder for
placing a powdered color thereon, said cylinders
being timed to superimposeA the color on the
base
impression.

each lever to fix the extent of movement of the
surface of the transfer roller 2G is substantially
the same as the linear movement of the periph

After the proper color has been impressed up

on the sheet Z it may be re-rolled upon a supply
contacting with the color cylinder for placing a
powdered color thereon, said cylinders being
roll or passed directly into the 'cigarette machine,
the details of whichy form no part of the present
Invention. In Figure 3 there is disclosed a sheet`
Z upon which the base impression 38 has been im
70 pressed, and upon this base impression a top or
having the web trained thereover, means for
placing a `|mucilaginous substance on the base
cylinder for Aimpression on the web, and means
timed to superimpose the color on the base im
pression.
