I SERGAY JAKOOLEVITCH TIMOHOWITSCH of the town of Troitskaia in the Govern-
ment of Kalonga and Russian Empire, Mechanical Engineer, do hereby declare the
nature of my Invention for "AN IMPROVED APPARATUS FOR PRODUCING LINES IN
PAPER IN THE WEB "to be follows :—
The object of above apparatus is to produce lines on paper of different intensity, by
pressure. The construction of said apparatus consists in a chilled cast iron roll
against the under side of which two rows of discs press. The spindle or axis of said
discs rest in square blocks which lay free side by side in two beams which rock upon
their pivots. Each bar has a piece of india rubber, upon which screws opernie so as
to produce a certain pressure (about 30 lbs.) upon each disc.
By means of said screws an increased or decreased pressure is produced upon the
discs, and a more or less intensive line upon the paper.
Appropriate rolls draw and unwind the paper off the paper roller, and a roller is
further provided on which the paper is wound-An excentric brings the small discs
in contact with the chilled cast iron roll.
Circular revolving knives are arranged for cutting the paper longitudinally,
The working of foregoing apparatus consists in leading the paper web from the
roll, and bringing the cast steel discs in contact with the chilled cast iron roller by
means of an excentric.
At the moment of contact the discs begin to revolve and the greater the pressure
upon the said dises the more intense will be the lines upon the paper. The distance
of the discs from each other depends upon the distance of the lines required upon the
paper.
The abovementioned discs can be made of any hard metal or glass and journaled in
any form of blocks.

beams G G¹.
The aforesaid rails F F are connected by means of connecting rods H H', to the
rod I, to the rear end of which said rod I an eccentric K is arranged, so as to provide
a backward and forward movement for the discs or small wheels E E', which are
rotated as soon as they are brought into contact with the paper drawn around the
chilled cast iron roller B.
The above-mentioned rails F F' have their bearings in the projections T T¹ and can
be adjusted by means of the screws u u¹.
In order to produce a more or less intense line or watermark on the paper, the
distance existing between the said paper and the small wheels or dises, is variable,
which variation is produced by the provision of an adjustment device to each of the
square blocks e e, consisting of a small groove or recess in the lower part of the said
blocks eel for the introduction of small pieces or strips of india-rubber or other suitable
flexible and elastic material g, upon which the pressure of the screws i is exerted by
means of the nut h. In this manner the discs or small wheels are provided with
elastic counter-bearings to equalize the pressure on the paper.
The chilled cast iron roller B with its bearings M, is so arranged as to allow a
longitudinal axial movement to be effected, whilst an involuntary, unnecessary move-
ment is prevented by means of the spring N and the counter screws 00¹. The
roller is placed in contact over the roller O¹ and by their action they reel the paper
from the roller B guide the same over the small roller d to the rewinding roller D.
In order to laterally adjust the rollers A and D a suitable regulating mechanism is
provided.
The operation of my improved apparatus is extremely simple and is carried out in
the following manner :-
The paper to be watermarked or lined is first drawn through the entire apparatus
from roller A over small rollers a a², around the chilled cast iron roller B, over
roller C, between rollers C C³, over small roller d to the rewinding roller D. The
apparatus is then set in motion by any suitable motive power, whereby the whole set
of discs or small wheels is brought into contact with and press on the paper
drawn around the cast iron roller B by the action of the eccentric K. At the moment
of contact the discs or small wheels commence to rotate and the intensity of the
watermarks corresponds to the pressure exerted by the said small wheels or discs on
the paper.
The width of the watermarked lines correspondingly determines the distance at
which the small wheels or discs should be placed from each other, but I desire it to
be understood that I make no claim to the manufacture of the small wheels or discs
out of any special material, as the same can be made of any hard metal, glass or
other suitable material and journalled in any form of blocks.
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. The herein before described apparatus for producing watermarks and lines of
certain intensity and breadth in or on paper, which apparatus contains a number
of elastic blocks e e, movably attached to suitable frames or rails FF and provided
with series or sets of small wheels or discs revolving freely on suitable pivots under
an equalizing elastic pressure, substantially as shown and described.
2. The herein described apparatus for producing watermarked lines in or on
paper or any mere modification of the same, substantially as shown and described.
