I WILLIAM HENRY BECK of 116 Cannon Street in the City of London,
Consulting Engineer and Patent Agent do hereby declare the nature of my
Invention for IMPROVEMENTS IN MACHINES FOR STAMPING OB ENGRAVING PRINTING
BOLLERS AND FOR SIMILAR PURPOSES a communication to me by Julius Müller,
Engraver, Zarewo, Russia to be as follows:-
"
This Invention relates to improvements in automatic stamping engraving and
etching apparatus and in adjustable spindles for engraving or milling machines..
The previous method of applying figures or designs to copper rollers for calico
printers consisted in impressing engraved stamps or dies into the copper rollers by
means of a suitable lever mechanism.
In employing this method two operations were required, the one to give the
roller, which carries the milling or engraving wheel, the requisite rotary movement
the second to cause the stamp or die to act on the roller by means of the hand.
lever mechanism.
By applying an apparatus to the milling or engraving machine the action of the
milling or engraving wheel and hand lever is carried out simultaneously and
automatically whereby an adjustable screw is employed in order to attain a like
deep impression of the stamp or die in the roller. By employing my apparatus
regular repeated figures can be automatically pressed into the roller in spiral form
and if desired shaded design or designs, figure or figures impressed in the said
roller by means of the stamp or die.
My improvements in engraving or milling machines or turning engines relates
further to an etching apparatus by means of which and a diamond pin any desired:
kind of etching of the roller prepared with etching varnish can be produced.
A further improvement consists in the arrangement and construction of an
adjustable spindle for the reception of the copper roller so as to prevent the same
from becoming unround and also to prevent all concussions.
The above named improvements can be employed with milling or engraving
machines or turning engines of various constructions but are especially adapted for
employment with the Ducommon apparatus.

page_text: An important feature of my invention is the arrangement or a suitable Suare
parallel to the guide spindle which said shaft is provided with a longitudinal groove
and receives a uniform movement from the toothed wheels or an intermittent
movement by means of a disc with suitable stud or pin.
The method of operating the shaft depends on the kind of design which it is
desired to produce on the copper roller or cylinder.
A suitable cam, the nose of which slides in the longitudinal groove of the main
shaft is arranged on the said shaft. The movement of the cam to the right and
left is effected by a double bearing attached to the slide which said bearing can bo
moved with the slide latorally by means of a screw spindle. A roll glides on an
excenter and rotates on a pin or pivot, the fork to the screw which said pin can
move in a vertically prolonged slot in the double bearing in order to permit the
rising and sinking of the roll.
The rotation of the shaft causes a rotation of the excenter and a rising and
sinking of the screw which is connected to the roller, which said screw is firmly
connected to the head piece by means of a suitable arm.
When the excenter has reached its highest point the engraving tool or die with
the head piece is withdrawn from the copper roller so that when the shaft has
bern r. tated 180° the said engraving tool or die is pressed onto the copper roller
by means of the lever mechanism which is connected to the head piece-In order
to render this pressure perfectly. equable I connect the arm with an adjusting
device consisting of a screw spindle the upper end of which is formed with a loop
through which the arm is pushed. The lower end of the spindle is screwed into an
elongated nut which ends in a pivot, which moves up and down in a bearing
connected to the slide. The nut is now so‘adjusted that when the stamp die or the
graving tool is in contact with the roller, the nut rests on the bearing surface and
the stamp die or graving tool is prevented from penetrating further which said nut
is held, in this position by means of the pawl.
When a stamp die or graving tool is employed for operating on the roller the
apparatus places the stamp or die automatically at a distance corresponding. to the
pattern or sample when the said pattern can be produced in spiral form. If
however the single figures are in a plane rectangular to the axis of the roller the
lateral motion of the slide is produced by turning the dividing disc on the screw
spindle by the hand.
The holder for the stamp die or graving tool is held in suitable bearings and
has lateral play in the same, which is necessary for the spiral movement of the
die or engraving tool.
In raising the tool from the roller the holder is pressed back into its original
position by a spring and is held in its vertical position by means of the arresting
pin or stop-The rotation of the roller in correspondence with the height of the
pattern is effected by means of the excenter on the shaft as the same transmits its
motion by means of the connecting rod and lever, to the dividing disc which is in
connection with the aforesaid roller.
As soon as the lever rises, the pawl glides over the teeth of the dividing disc or
divider whereas the pawl gears with the said divider when the lever makes its
downward movement and in this manner communicates a part revolution to the
said divider or dividing disc and the roller.
The downward stroke of the lever P is limited to the corresponding height of the
pattern by means of the stop pin.
As soon as the lever comes in contact with the pin the double spring which is
connected to the connecting rod, recedes so far that the excenter can rotate.
In order to produce shaded stripes on the copper roller 1 employ an apparatus
the principal part of which consists of the tappet wheel or disc b which is arranged
to rotate on the spindle box.
▸
. The tappet, wheel and roller are driven by means of the gearing after the
toothed wheels have been placed out of gear and the excenter on the roller set out
i

page_text: of operation-The tappet wheel is provided with from 1 to 6 radial slots in which
stop pins u can be arranged.
As soon as the pin strikes against one of the arms of the two armed lever
centred on the pin or pivot the other arm will be raised so that the pawl which is
connected to the said lever communicates a part revolution to the toothed wheel
and consequently also to the spindle which causes a rising and sinking of the head
or holder to the stamp or die by means of the excenter.
The lateral movement of the slide with the head is automatically effected by
means of the toothed wheel. Through the rotation of the roller and the lateral
movement of the head and the stamp, die or graving tool connected to the same
the latter is compelled to make a spiral movement on the said roller. Through
the raising and sinking of the head by means of the excenter the die, stamp or
graving tool is pressed more or less deep into the roller and in, this manner shaded
lines produced.
"
In order to produce various etchings in the varnished surface of the roller with
an etching diamond I employ an apparatus which is screwed to the slide or
carriage.
The connection between the excenter and the head is released, the adjusting
device removed from the slide or carriage and the toothed wheels brought into
gear.
On the spindle which is screwed to the slide or carriage and is provided near the
lower end with a conical collar but is otherwise of cylindrical form, sits a revolving
tube or case to the upper part of which the etching or drawing diamond is attached
whilst an angle lever is attached to the lower end of the same. The spring acts on
the one lever arm and presses the other arm onto a wheel on the shaft which said
wheel is similar in form to a bevel wheel with irregular incisions cuts or recesses
and produces the form or the shading of the curved or serpentine lines.
As the spring presses the one arm of the angle lever into the recesses of the
wheel the muff, tube or case which is firmly connected to the lever is caused to
make an oscillating movement around the axle which said movement is communi-
cated to the diamond by means of the holder or carrier and in this manner the
engraving or etching produced on the roller.
By means of the rotation of the said roller and the simultaneous advancing of
the slide or carriage with the spindle a vibrating line is produced on the roller, the
pitch of which depends on the advancing motion of the slide or carriage or on the
form of the wheel.
A horizontal spindle has its bearings in the holders on the slide beneath the
diamond holder and carries at its one end a weight attached to the arin whilst the
other end is connected to the pawl lever by means of an arm and the jointed or
articulated rod.
The cam on the shaft communicates an alternate reciprocal motion to the lever
by means of which said movement the diamond holder is made to approach and
recede from the roller. The remaining parts of the device are the same as already
described.
The bevil wheel which rotates with the shaft produces the rotation of the vertical
spindle by means of the bevel wheels.
The shaft of the conical or bevel wheels and the journal bearings for the spindle
are connected to the slide or carriage. A muff or case is pushed over the spindle
and is provided at the upper end with an arm the one end of which reaches over
the roller and carries a rotary roller the lower surface of which holds an excentrically
adjustable diamond-The spindle carries further at its upper end a roller which is
connected to the roller by a band or cord so as to set the said roller in rotation.
Through the rotation of the roller the diamond which is excentrically attached to
the same is caused to produce circular lines on the roller which merдe into
circularly interwoven lines through the simultaneous rotation of the said roller.
In order to vary the form of these interwoven lines a suitable lever can be
allowed to act on the wheel which is at the periphery provided_with irregular cuts

page_text: or recesses so that the case or muff and the roller which carries the diamond execute
a horizontal oscillating movement-The adjustable spindle serves to centre the
copper roller and to prevent the same diverging or taking an excentrical position.
The copper rollers were formerly driven onto a conical spindle by means of a
suitable press and the faulty centering of the said roller was generally caused by
the boring of the roller seldom corresponding to the conicity of the spindle.
The spindle is at both ends as far as the roller comes in contact with the same
provided with two opposite grooves running inclined towards the axis, in which
said grooves wedge like keys of corresponding length, fit.
The keys can be driven in according to requirements and the roller centrally
fixed at its ends by screwing up the screw, the male threads of which fit into the
female threads of the same keya.

Consulting Engineer and Patent Agent do hereby declare the nature of my
Invention for "IMPROVEMENTS IN MACHINES FOR STAMPING OR ENGRAVING
PRINTING ROLLERS AND FOR SIMILAR PURPOSES" a communication to me by Julius
Müller of Zarewo, Russia, Engraver, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to improvements in automatic stamping, engraving and
etching or guilloshing apparatus and in adjustable spindles for rose or engraving
engines.
The previous method of applying figures or designs to copper rollers for calico

means of a suitable lever mechanism.
In employing this method two operations were required, the one to give the

14, 15 and 16 represent in top view, side view and elevation a second
modification in order to produce the etching by means of circular lines.
An important feature of my invention is the arrangement of the shaft A parallel
to the guide spindle B which said shaft is provided with a longitudinal groove and
receives a uniform movement from the toothed wheels a a' a' or an intermittent
movement by means of a disc with suitable stud or pin.
The method of operating the shaft A depends on the kind of design which it is
desired to produce on the copper roller or cylinder.
A suitable came the nose of which slides in the longitudinal groove of tho
shaft A is arranged on the said shaft.
The movement of the cam c to the right and left is effected by the double
bearing d d attached to the slide D which said bearing d can be moved with the
slide laterally by means of the screw spindle B.
A roller e glides on the excenter c and rotates on a pin or pivot in the fork to
the screw (Figures 1, 3, 7) which said pin can move in a vertically prolonged
slot in the double bearing d in order to permit the rising and sinking of the
roller e.
The rotation of the shaft A causes a rotation of the excenter c and a rising and
sinking of the head-piece F and the screw f which is connected to the roller e
which said screw is firmly connected to the head piece F by means of the arm E.
When the excenter c has reached its highest point the engraving tool or die with
the head piece F is withdrawn from the copper roller H so that when the rotation
of the shaft A is continued the weight of the heavy head piece F will causo the
same to sink turning round the fulcrum F¹ and thus pressing the die or engraving
tool into the copper roller H by the weight of the said head piece F.
In order to render this pressure perfectly equable I connect the arm E (Figures 3
and 9) with an adjusting device consisting of a screw spindle I the upper end of
which is formed with a loop through which the arm E is pushed.
The lower end of the spindle I is screwed into an elongated nut g which ends in
a hollow pivot, which moves up and down in a bearing connected to the slide D.
This nut g. acts as a stop for regulating the depth of the impression or engraving of
the roller H and can be screwed backwards or forwards so as to allow the said
etamp, die, or engraving tool to penetrate the surface of the roller H more or less.
The nut is now so adjusted that when the stamp die or the graving tool G
is in contact with the roller H the nut g rests on the bearing surface h and the
stamp, die or graving tool is prevented from penetrating further which said nut
is held in this position by means of the pawl i.
g
When a stamp or impressing tool is employed for operating on the roller the
apparatus places the stamp or die automatically at a distance corresponding to the
pattern or sample when the said pattern can be produced in spiral form.
If however the single figures are in a plane rectangular to the axis of the roller,
the lateral motion of the slide D is produced by turning the dividing disc on the
screw spindle B by the hand.
The holder K for the stamp or impressing tool (Figure 10) is held in the
bearings kk and has lateral play in the same which is necessary for the spiral
movement of the said stamp, die or engraving tool.
In raising the tool from the roller H the holder K is pressed back into its
original position by the spring 7 and is held in its vertical position by means of the
arresting pin or stop m.

page_text: The rotation of the roller H in correspondence with the height of the pattern
is effected by means of the excenter n on the shaft A as the same transmits its
motion by means of the connecting rod o and lever p (Figures 1, 2, 4, 7) to the
dividing disc L which is in connection with the roller H.
As soon as the lever p rises the pawl q glides over the teeth of the dividing disc
or wheel L whereas the pawl gears with the said dividing wheel or disc L when
the lever makes its downward movement and in this manner communicates a part
revolution to the said dividing disc and the roller H.
The downward stroke of the lever p is limited to the corresponding height of the
pattern by means of the stop pin r. As soon as the lever p comes in contact with
the pin r the double spring t which is connected to the connecting rod o, recedes so
far that the excenter n can rotate.
In order to produce shaded stripes on the copper roller HI employ the apparatus
as shown in the complete machine Figures 1 and 2 and in detail in Figure 6, the
principal part of which consists of the tappet wheel or disc b which is arranged to
rotate on the spindle box M.
The tappet wheel b and roller H are driven by means of the gearing V after the
toothed wheels a a¹ a³ have been placed out of gear and the excenter n on the
roller H set out of operation.
The tappet wheel b is provided with from 1 to 6 radial slots in which stop
pins u can be arranged. As soon as the pin u strikes against one of the arms of
the two armed lever centred on the pin or pivot v, the other arm will be raised so
that the pawl Q which is connected to the said lever, communicates a part
revolution to the toothed wheel R and consequently also to the spindle A which
causes a rising or sinking of the head or holder to the stamp or die G by means of
the excenter c.
The lateral movement of the slide D with the head F is automatically effected
by means of the toothed wheel a³. Through the rotation of the roller H and the
lateral movement of the head F and the stamp, die or graving tool connected to
the same the latter is compelled to make a spiral movement on the said roller.
Through the rising and sinking of the head F by means of the oxcenter o the die,
stamp or graving tool is pressed more or less deep into the roller and in this
manner shaded lines are produced.
In order to produce various etchings in the varnished surface of the roller H
with an etching diamond I employ the apparatus shown in Figure 11 which is
secured to the slide or carriage D. The connection between the excenter o and the
head is released, the adjusting device I removed from the slide or carriage and the
toothed wheels a a¹ a¹ brought into gear.
On the spindle w which is screwed to the slide or carriage D and is provided
near the lower end with a conical collar but is otherwise of cylindrical form, sits a
revolving tube or case S to the upper part of which the etching or drawing
diamond is attached whilst an angle lever is attached to the lower end of the
same.
The spring y acts on the one lever arm and presses the other arm onto a wheel &
on the shaft A, (Figure 12) which said wheel is similar in form to a bevel wheel
with irregular incisions cuts or recesses and produces the form or the shading of
the curved or serpentine lines.
As the spring y presses the one arm of the angle lever into the recesses of the
wheels the muff, tube or case S which is firmly connected to the lever x is caused
to make an oscillating movement around the axle n which said movement is
communicated to the diamond by means of the holder or carrier T and in this
manner the engraving or etching produced on the roller H.
By means of the rotation of the said roller and the simultaneous advancing of
the slide or carriage D with the spindle wa vibrating line is produced on the
roller H the pitch of which depends on the advancing motion of the slide or
carriage D or on the form of the wheel .
The Figures 12 and 18 show a modification of this device..

page_text: A horizontal spindle 1 has its bearings in the holders 2 and 3 on the slide D
beneath the diamond holder and carries at its one end a weight attached to the
arm 4 whilst the other end is connected to the pawl lever 7 by means of the arm 5
and the jointed or articulated rod 6.
The cam 8 on the shaft A communicates an alternate reciprocal motion to the
lever 7 by means of which said movement the diamond holder is made to approach
and recede from the roller H. The remaining parts of the device are the same as
already described with reference to Figure 11.
The form of the wheel z can be best seen in Figure 12. If the etching or
engraving on the rollor H is to be made in circular instead of serpentine lines the
device (Figure 11) must be replaced by the device shown in Figures 14, 15, 16.
The bevil wheel 9 which rotates with the shaft A produces the rotation of the
vertical spindle 13 by means of the bevel wheels 10, 11, 12. The shaft 14 of the
conical or bevil wheels 10, 11 and the journal bearings for the spindle 13 are
connected to the slide or carriage D. A muff or case 19 is pushed over the
spindle 13 and is provided at the upper end with an arm 16 the one end of which
reaches over the roller H and carries a rotary roller 17 the lower surface of which
holds an excentrically adjustable engraving diamond.
The spindle 13 carries further at its upper end a roller which is connected to
the roller 17 by a band or cord (Figure 14) so as to set the said roller 17 in
rotation.
Through the rotation of the roller 17 the diamond which is excentrically
attached to the same is caused to produce circular lines on the roller Ḥ which
merge into circularly interwoven lines through the simultaneous rotation of the
said roller.
In order to vary the form of these interwoven lines the lever 15 (Figure 14) can
be allowed to act on the wheel which is at the periphery provided with irregular
cuts or recesses so that the sleeve or muff 19 and the roller 17 which carries the
diamond, execute a horizontal oscillating movement.
The adjustable spindle U (Figure 8) servos to centre the copper roller H and to
prevent the same diverging or taking an excentrical position.
.
The copper rollers were formerly driven onto a conical spindle by means of a
suitable press and the faulty centering of the said roller was generally caused by the
boring of the roller seldom corresponding to the conicity of the spindle.
.
The spindle U (Figure 8) is at both ends as far as the roller comes in contact
with the same provided with two opposite grooves running inclined towards the
axis in which said grooves wedge like keys of corresponding length fit.
The keys can be driven or screwed in according to requirements, and the
roller H centrally fixed at its ends by screwing up the screw 8¹ the male threads of
which fit into the female threads of the said keys k².
Having now particularly described and ascertained the nature of my said
