Improvements in or relating to Stamping or Printing Apparatus.
I, KNUT EDWARD WIBERG, Engineer, of Björngardsgatan 9 B, Stockholm,
in the Kingdom of Sweden do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
'
This invention relates to a stamping apparatus for stamping various numbers of
figures on loose sheets of paper or on a continuous strip of paper.
In the accompanying drawings
Fig. 1 represents the apparatus in section through lines I-II (Fig. 2), Fig. 2 is
a plan and Fig. 3 a section through lines III-IV (Fig. 2).
The same letters relate to corresponding parts of the different figures.
The apparatus consists of following parts
Between the semi-circular guides a there move the segments or plates 6 con-
centrically with the former, these segments being provided on their upper surface
with ciphers from 0 to 9 and on their lower side provided with teeth. These teeth
gear into the cog-wheels c fastened on one side of the printing plates d which are
provided on their circumference with types from 0 to 9. The movement of the
segments b round the common centre causes the printing-plates to turn round. On
the opposite side of the printing-plates d the cog-wheels e are placed, which gear
into the cog-wheel 9 placed on the one side of the printing-plates f. These latter
printing plates as the plates d are provided with types 0 to 9. On their opposite
side are fastened the ratchet-plates in which gear the pawl levers i pivotted
on the shaft h¹. The pawls are pressed against the ratchets h by the spiral
springs k.
The printing-plates d with their cog-wheels thereon rotate round the fixed axle k¹
and the printing-plates with their cog- and ratchet-wheels round the fixed axle k².
The helical springs threaded on the shaft l' have a tendency by means of the
chains m fastened to the cog-wheels e to turn the above mentioned system of plates
and wheels in a direction opposed to that in which it rotates when the segments b
are turned from right to left between the guides a (Fig. 2); the movement caused
by the springs being limited by the pawls i engaging in the teeth of the ratchet-
plate h. The pawls i are disengaged from the teeth by lifting up the handle o on
the shaft p, the plate g¹ attached to this shaft p is then pressed against the lower
end of the pawls in consequence of which their upper ends are removed from the
teeth of the ratchet plates. In this manner the aforementioned plates and wheels
as well as the segments 6 are brought back to their previous position, by means of
the spiral springs l.
The mechanism hitherto described is, with the exception of the guides a and the
plates b enclosed in a box r in the front and back walls of which the shafts k¹h k² l'
and p are firmly fixed. To these same walls the sliding pieces s and t are connected
by the wings and by means of which the box may be raised and let down along
the standards u and v which thus act as guides.

page_text: The guides a form the upper covering of the box and are firmly fastened thereto.
In the side walls of the box the journals x and y are fixed. Under the foremost
wing there is a hollow which contains the colour pad z. Round the journals
andy and lying nearest to the side walls of the box the arms a¹ and a move,
supporting the colour roller o' which moves in grooves formed along the longitudinal
axes of these arms and the said roller is drawn upwards by the spiral springs A
and B. The colour-roller runs first over the colour-pad z and afterwards touches
the lower part of the printing plates d and f.
The up and down motion of the box r is caused by the arms C and D which are
movable around the shafts G fixed in the socket-stands E F. The arms C and D
are by means of grooves made therein, threaded over the journals & and y and thus
oblige the box to move along the standards u and v, when the arms turn round the
shaft G. The foremost ends of these arms are connected together by the revolving
shaft H in the centre of which and firmly fixed thereto the handle I is placed.
Besides this handle there is also affixed to this shaft the cranks K the lower ends of
which communicate with the arms a' and a' by the connecting rod L and the move-
ment of which is limited by the pins K' fixed to the arms C and D. The downward
motion of these arms and of the box r is brought about by the handle I while the
upward motion is caused by the spiral springs M the one end of which are threaded
into the plate N firmly fixed on the shaft while the other ends embrace the
arms C and D.
The movement of the segments & from right to left on the guides a (Fig. 2) is
accomplished by the lower point of the pin O. This pin which at its lower end is
covered with leather, indiarubber or some other material of high friction is freely
suspended in the fork P and by this fork connected with the tube R running inside
the tube Q. In the bottom of this outer tube a guiding rod S is placed along which
the inner tube R moves and round which a spiral spring T is wound one end of
which rests against the bottom of the inner tube R the other end resting against the
pin
U in the foremost part of the rod S causing the return of the tube R when it
has been drawn out. Both the tubes as well as the pin O are movable in a vertical
direction by means of the journals V resting in the upper fork-like part of the
plate W. When the foremost ends of the tubes are bent down they are returned
against the shoulder X by the spring Y. The plate W is connected with the under
plate Z and together with this plate is movable in a horizontal direction round the
pillar A which by the table A is attached to the upper end of the standards v
being placed in the common centre of the guides a and segments b. In the lower
cylindrical part of the plate Z a notch is made by means of which the plates W
and Z as well as the mechanism attached thereto may be turned so far to the left
(Fig. 2) that the aforementioned notch in the plate Z strikes against the bolt O¹
passing through the pillar A'. Practically a universal motion is in this manner
given to the pin O.
The two standards
and vas also the socket-stands E F are mounted on a
common bed plate a a. In a hollow formed in the same there is a mechanism for
the movement and winding of the continuous paper strip.
A stand bb fastened to the bed-plate a a supports the paper roll cc from which a
strip of paper runs round the printing roller dd to the winder ee where it is
threaded into a groove running longitudinally along this winder and is consequently
wound round it when the winder is turned.
The motion is imparted to the winder by a movable lever arm ff which is fixed
to the shaft of the winder and which supports the pawl g g connected with and
placed on the selfsame shaft. The pawl gg is influenced by the spring h h. The
downward motion of the lever arm ff is caused by the downward movement of
the box r when this strikes against the pin k k which is applied to the lever arm
and forces it at the same time to turn on the shaft of the winder.
The upward motion of the lever arm ff is induced by the spiral spring ii placed
on the previously mentioned shaft when by the pawls g 9 catching the cog-
wheel g¹g the roller e e is made to turn round.

page_text: The stamping of a certain number is thus accomplished:
The desired number is adjusted by means of the segments b in such a manner
that the lower end of the pin O is placed on that figure of the inner segment which
corresponds to the first figure of the number in question, whereupon the segment,
by means of the pin is moved from right to left till the pin stops in consequence of
the cylinder of the plate Z striking against the bolt passing through the pillar A'.
The gearing between the segments 6 and the cog-wheels c as also between the
cog-wheels c and g is so arranged that when the pin O stops as described above,
the same figure on which its point has been placed is then lowest on the printing-
plates d and f. Afterwards the other figures of the number in question are
adjusted in the same manner from the inmost segment to the outermost in the same
order as the sum is read which may also finally be read radially in the vertical
plane in which the pin O stops.
The handle I is then grasped and bent towards the person working the apparatus
until the cranks & stop against the pins ¹ when the colour roller o' by means of
the revolution of the shaft G and the movement of the arms a' and a caused by
the cranks k and the connecting rods L is rolled over the colour-pad and the
adjusted figure-types and colours them. Afterwards the arms C and D are pressed
down and at the same time the box r and the printing plates contained therein are
pressed down against the bed-plate. The coloured types are now imprinted as well
on the loose sheets of paper laid on the bed-plate by means of the printing plates d
as also on the continuous strip of paper against the printing-roller d d by the
plates f.
As a modification of the position of the figures on the upper side of the
segments b it may be mentioned that as shown in Fig. 2 on the ends of the plates
farthest to the right these figures might be placed on those parts of the guides a
which are inside the segments b when a single figure would in this manner point
out those parts of the surfaces of the segments b which are radially situated
relatively to the same.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is,―
A stamping apparatus for stamping varying sums or numbers simultaneously and
equivalently on a continuous strip of paper and on loose sheets of paper charac-
terized by the following features,―
1. The arrangement of the printing-plates consisting of two groups of circular
plates directly connected with each other by gearing and provided on their
peripheries with figure-types from 0 to 9 the plates being enclosed in a box movable
in a vertical direction.
2. The arrangement of the adjusting plates consisting of segments arranged
concentrically in the horizontal plane between guides and which by gearing commu-
nicate directly with one group of the printing plates the said adjusting plates being
for this purpose arranged on the box enclosing the printing plates.
3. The arrangement for guiding the adjusting plates consisting of an arm movable
both in a vertical and horizontal direction attached to a stand rising from the centre
of the adjusting plates and at its one end supporting a vertically suspended pin to
be placed on the adjusting plates and by being rotated about the aforesaid centre
to adjust these plates to fixed positions.
The whole operating substantially as described and illustrated in the
accompanying drawings.
