Improvements in Apparatus for Embossing by Means of Blocks in
the Production of Decorative Material, Panels, Architectural
Ornaments, and the like from Paper and other Materials whilst
in Motion, Applicable also for Analogous Operations, such as
Printing or Stamping upon Materials in Motion.
I. THOMAS JOHN PALMER, of Queen's Mill, Lancaster, in the County of
Lancaster, Decorative Material Manufacturer, do hereby declare the nature of this
invention to be as follows:-
My Invention relates principally to apparatus for the manufacture by blocks of
embossed decorative material panels architectural ornaments and such like articles
from partially manufactured paper or other materials but the said invention is also
applicable to analogous operations such as to printing or stamping materials whilst in
motion the said apparatus being arranged so that it can be adapted for use for
producing various lengths of "repeat" of the pattern embossed stamped or printed.
I will describe my invention with reference to producing embossed decorative
material from paper making material as it issues from a paper making machine from
which description the application of the said invention to analogous operations such
as printing or stamping materials in motion will also be readily understood. In
carrying out my invention according to the example which I have chosen for the
purpose of illustration I make a layer or web of paper pulp on the "wet end
paper making machine either in the way indicated in the Specification to my Patent.
No. 4227 of 1883 or in any other suitable way and after it has passed the coucher rolls
I convey it on to an endless felt and for some patterns I convey it by means of this
felt between rollers to press and consolidate it, whilst for other patterns I carry it
forward without pressing to be embossed in the state in which it leaves the coucher
rolls. To effect this embossing I arrange at a convenient point preferably in a direct
On the
line with the paper making machine a strong and suitably formed frame.
inner sides of this frame I fix plates having channels or grooves therein to receive
pins or brackets fixed to plates to which the embossing blocks are attached. The
plates are connected by brackets and sliding rods and links to rack bars through
"
of a

page_text: which the embossing blocks are operated as hereinafter described. The upper rack
bar passes up through a guide block and the lower rack bar is similarly guided by
a block which may be in a concrete base or bed. On two opposite sides of the
rack bars are teeth to engage with corresponding teeth on segment wheels by means
of which the blocks are caused to operate on the material being embossed.
To the bolts or pins which secure the brackets to the rack bars are attached
chains ropes or bands which pass round free running grooved pulleys and are connected
at their opposite ends to pulleys fast on shafts on which are fixed friction pulleys round
which pass friction straps leading from corresponding pulleys fast on second shafts. Fast
on the first named shafts are toothed wheels which at the required periods gear into
segment wheels fast on the second shafts in order to withdraw the blocks from the material
being acted upon as hereinafter described. When the said toothed wheels are not in gear
with the block withdrawing segment wheel the shafts first named will run free except for
the friction of the belts on the pulleys.
When the embossing blocks are in contact with the material they are caused to
move forward at the same speed as that at which the material is being fed to the
machine the pins in connection therewith sliding along the horizontal portions of the
grooves in the aforesaid plates and to admit of this longitudinal movement of the said
blocks the rack bars are made to act telescopically by rods sliding in slots in links
which connect the racks to the brackets the said links turning on centre pins. The
longitudinal movement of the blocks is effected by segment wheels gearing with
racks on the sides of the block plates. Immediately after the plates and dies bave
completed their horizontal motion and the pins arrive at the end of the horizontal
portions of the slots the block travelling segment wheels will have become disengaged
from the racks leaving the plates and dies free to be withdrawn from the material.
The block travelling segment wheels receive a little less than half a revolution at a
time and are driven by means of wheels on upright shafts which rotate continuously.
To prevent the block travelling segment wheels upon disengagement being carried
round by their inertia so as to come into gear at the wrong time with the racks and
wheels respectively I provide an arrangement which stops their free motion and
retains them out of gear-also causing them to go into gear again at the proper
time. This arrangement is provided at each side of the apparatus and consists of a
vertical cylinder fixed to the frame and containing a spring which constantly maintains
a downward pressure through a rod upon a slider tending to keep it at the
lower limit of its travel in a guide slot. This slider projects into the vertical groove
of one of the plates so that as the embossing blocks or dies come into position in
readiness to receive horizontal traverse the pin in connection with the die may strike
the said projection and raise the slider against the resistance of the spring in the
cylinder. The raising of the slider lifts the tail ends of two plate springs which are
secured thereto and the other ends of these springs are constrained to move forward
horizontally by guide and guide pins. Studs are fixed to the underside of block
travelling segment wheel each in such a position that one end of the second spring
being forced forward comes into contact with a stud and thereby pushes the block
travelling segment wheel into gear with the rack on the die carrying plate and with
the wheel gearing with the block carrying segment wheel with the result that each
die is traversed horizontally. As soon as the pin in its horizontal travel leaves the
underside of projection on the slider the said slider is caused to fall to its lowest
position by the spring in the cylinder and the first and second springs resume their
original positions in readiness for another operation.
A hinged stop-piece is carried by the first spring and lies between guide pins so
arranged that the said stop piece is lowered out of the way of the stud on the block
travelling segment wheel at the same moment that the second spring pushes at the
opposite side of the stud, but as soon as the horizontal travel of the die plate and its
pin permits the slider to fall the consequent withdrawal of the end of the first spring
elevates the upper edge of the said stop piece so as to intercept and stop the stud on
the said segment wheel and thereby prevent the said segment wheel from making more
than half a revolution. This applies at both sides of the machine.

page_text: I will now describe the means by which the apparatus is driven, together with the
arrangement for varying the speed of withdrawal and return of the dies in accordance
with the length of repeat in the pattern being embossed to enable different lengths
of repeat being produced by the machine and prevent the length of pattern last
embossed from overlapping or from falling short of the length of pattern just
previously embossed, it being understood that the paper or pulp from the coucher
roller passes through the apparatus at a constant speed. The shafts which drive the
gearing giving horizontal traverse to the dies are geared with the coucher roll driving
gear so that the speed of the pulp through the apparatus may always be the same as
the horizontal speed of the embossing dies.
The mechanism herein before described for controlling the rise and fall of the embossing
dies may be driven by the well known double cone arrangement for variable speed,
the belt transmitting motion from one cone to the other being provided with a belt
shifter capable of being operated by the attendant by means of a handle and rope.
which passes around the pulleys one of which operates a screw which causes the belt-
shifter to traverse the belt when variations of the length of period between successive.
embossings are required. The notion of the belt is transmitted from the pulley to
one of the aforesaid segment wheels engaging with the racks and in order that the
movements of both the rack bar segment wheels may be synchronous, their shafts.
are geared by toothed wheels or other suitable gearing. The rack rods are also
driven synchronously by gearing.
I will now describe the action of the machine starting with the assumption that the
pulp or paper is just commencing to receive an impression. The block travelling
segment wheels running at the same speed as the pulp or other fabric to be treated
are in gear with the racks of the die plates and the dies are carried forward hori-
zontally. The edges of the upper parts of the grooves in which the pins in connection.
with the dies engage are for about one third of their length slightly inclined towards
the dies so that as they are carried forward the pressure upon them is gradually
increased until they have passed through about one third of their travel when the
maximum pressure is reached and is maintained until the ends of the said upper part.
of the grooves are reached and the dies are withdrawn respectively up and down the
inclined grooves. During the horizontal traverse of the dies the telescopic portions
of the rack bars are extended, and as the pins reach the ends of the upper portion
of the grooves the racks on the edges of the die carrying plates will have cleared the
block travelling segment wheel and the stud on that wheel comes into contact with
the aforesaid stop piece and the wheel is prevented from being carried further round
by its momentum. At the moment that the die carrying plates cease to receive.
motion from the said segment wheel the block withdrawing segment wheels engage
with the toothed wheels on the shafts on which are the rollers over which the aforesaid
cords pass so that these cords which are attached to the bolts of the rack bars draw.
the die plates with their dies so that their pins move along the inclined parts of
the aforesaid grooves. In doing so the telescopic portions of the rack bars are. first
pulled home and then the rack bars still operated by the cords are respectively elevated
and depressed until the pins of each of the die plates have arrived at the end of
the inclined parts of the grooves in readiness to traverse the vertical portions of
the grooves, the lower rack bar is provided with a spring of sufficient strength to
prevent its descent under the influence of gravity while its telescopic portions are
being returned as described. By the time these operations are concluded the rack
bar segment wheels will have reached the point of gearing into the rack bars
which latter will immediately carry the die plates and the dies along the vertical
portions of the grooves into contact with the material being embossed or treated the
rack bar segment wheeis being by this time out of gear again with the racks. The
upper die plate is prevented from running away from its rack bar and link by the
retarding influence of the friction of the belt upon the pulley. As the lower die and
its plate arrive at the upper end of the vertical portions of the grooves (the upper die
block simultaneously arriving at the bottom of its grooves) one of the pins of the
lower plate strikes and raises the aforesaid slider which actuates the second spring

page_text: which in turn acting upon the pin of the block travelling segment wheel forces it
into gear with the revolving wheel on the vertical shaft and with the racks of the die
plates which are then with their dies traversed horizontally as described.
If in embossing or printing it is found that the die or block is either overlapping
or not quite reaching the work just previously done, by reason of the slight slipping
of any of the belts or because of any inequalities in the repeat of the pattern of the
material being printed the attendant in charge can immediately rectify this by
operating the belt shifter and so increasing or decreasing the speed of that portion
of the machine which operates to cause the withdrawal and return of the dies.
The means for increasing or decreasing the speed of that part of the machine
which withdraws the die or block will allow of considerable variation in the length
of repeat in the patterns being embossed or printed. It will be readily seen that the
power of varying the speed of this part of the machine is capable of allowing any
length of fabric (varying say for example from 21 inches to six feet) passing each
time before the die or block returns to the fabric, but if working short repeats it will
be necessary to decrease the length of the aforesaid grooves in the plates so that they
have a less proportionate length to that of the die or block.
When embossing pulp direct from the couch rolls I use one or more thick wet
felts to absorb the water pressed out, or I may use the arrangement described in the
Specification of my Patent No. 422783 I bore holes through the counter die at suit-
able points to allow of the escape of water from the material operated upon and when
desirable I also bore the embossing die in the same manner, but when I do this
I plug the holes bored in the embossing die with porous material at those points
where the water is found to be driven in the operation of embossing.
For these plugs I prefer to use clay and to mix it with napthaline or other
spirit then bake it to drive off the spirit taking care not to raise the temperature too
high. When the spirit has been driven off I form the clay into plugs of suitable
shape and secure them in the orifices in the die by cement or otherwise.
When using the hereinbefore described machine for printing I attach to it one of
the many well known arrangements for inking or coloring the surface of a block
that is in position with its face downwards. For printing or other purpose not
requiring a counter die I put in a fixed bed plate to receive the pressure when the
printing block or device is pressed onto the material being treated.
If I wish to emboss or otherwise act on impressed or but lightly pressed paper
pulp (or even upon dry paper) by blocks arranged according to my invention but by
an operation distinct from the making of the paper I wind the paper on a roller or
drum and convey it to be embossed by the blocks arranged to operate according to my
invention.
It will from the foregoing description be understood that printing blocks or other
equivalent devices which are required to act at intervals upon a web of material
in motion to emboss print or stamp the same can replace the dies illustrated.

the Production of Decorative Material, Panels, Architectural
Ornaments, and the like from Paper and other Materials whilst
in Motion, Applicable also for Analogous Operations, such as
Printing or Stamping upon Materials in Motion.
I THOMAS JOHN PALMER of Queens Mill Lancaster in the County of Lancaster
Decorative Material Manufacturer do hereby declare the nature of this Invention
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 principally to apparatus for the manufacture by blocks of
embossed decorative material panels architectural ornaments and such like articles from
partially manufactured paper or other materials but the said Invention is also applicable
to analogous operations such as to printing or stamping materials whilst in motion the
said apparatus being arranged so that it can be adapted for use for producing various
lengths of "repeat" of the pattern embossed, stamped or printed.
I will describe my Invention with reference to the accompanying drawings as
applied to the production of embossed decorative material from paper making material
as it issues from a paper making machine from which description the application of
the said Invention to analogous operations such as to printing or stamping materials
in motion will also be readily understood. Figure 1 is an end elevation, Figure 14 a
view at right angles thereto of part of the same and Figure 2 a diagrammatic
transverse section of an apparatus constructed according to my Invention. Figure 3
is a part plan and Figures 4 to 9 are detail views and modifications of portions thereof
as hereinafter explained. In carrying out my Invention according to the example
which I have chosen for the purpose of illustration I make a layer or web of paper
pulp on the "wet end" of a paper making machine, either in the way described in
the Specification to my Patent No. 4227 of 1883 or in any other suitable way and
after it has passed the coucher rolls I convey it on to an endless felt and for some
patterns I convey it by means of this felt between rollers to press and consolidate it,
whilst for other patterns I carry it forward without pressing to be embossed in the
state in which it leaves the coucher rolls. To effect this embossing I arrange at a
convenient point preferably in a direct line with the paper making machine a strong
and suitably formed frame A. On the inner sides of this frame I fix plates B B, B2 B2,
having channels or grooves a therein as shown in Figure 2 to receive pins Con
brackets C fixed to the plate D D2 to which the embossing blocks E E' are affixed by
screws or in other convenient way. The plates D D are connected by brackets F F²
sliding rods ff2 and links g g² to rack bars G G2 through which the embossing
blocks E E are operated by the segment wheels I I I² 12 operated by gearing as
hereinafter described. The upper rack bar G passes up through a guide H and the
lower rack bar G2 is similarly guided by a guide H2 which may be in a concrete base
or bed. On two opposite sides of the rack bars G and G2 are teeth h h² to engage
with corresponding teeth on the segment wheels I I².

page_text: J J2 are bolts or pins which secure the brackets F F2 to the rack bars G G2 and to
these bolts or pins are attached chains (or ropes or bands) kk2 which are guided by
free running grooved pulleys K K, K2 K2 and are connected at their opposite ends to
pulleys LL, L2 L2 fast on shafts M M² on which are fixed the friction pulleys N N'
round which pass friction straps N³ N¼ leading from corresponding pulleys No No fast
on shafts M3 M. Fast on the shafts M M² are toothed wheels P P2 which at
the requisite periods gear with the teeth of segment wheels R R2 fast on the
shafts M³ M in order to withdraw the blocks E E2 from the material being acted
upon as hereinafter described. When the wheels P P² are not in gear with the
segments R R2 the shafts M M2 will run free except for the friction of the belts N³ N*
on the pulleys N N and N2 No respectively.
When the blocks E and E2 are in contact with the material as shown in the drawings
they are caused to move forward at the same speed as that at which the material is
being fed to the machine the pins (sliding along the parallel portions 22 of the
grooves and to admit of this longitudinal movement of the said blocks the rack
bars G G2 are made to act telescopically by the heads of the rods ff2 sliding in slots
in the links g g² which connect the rack bars G G2 to the brackets F the said links
turning on the pins J J2 at one end and the pins jj at the other end. The longitudinal
movement of the blocks is effected by the teeth of the segment wheels U gearing with
racks add d² respectively on opposite sides or edges of the plates D D2 (Figure 3).
Immediately after the plates D D2 and blocks E E2 have completed their forward travel
and the pins C¹ arrive at the end of the parallel portions of the slots the segment
wheels will have become disengaged from the racks d leaving the plates D D² and
blocks E E2 free to be withdrawn from the material.
The segment wheels U receive a little less than half a revolution at a time and are
driven by means of the wheels 1 on shafts 2 which rotate continuously.
To prevent the segment wheels U, upon disengagement, being carried round by
their momentum so as to come into gear at the wrong time with the racks d d² and
wheels 1 respectively I provide the arrangement (shewn at Figures 4, 5 and 6) which
stops their motion and retains them out of gear-also causing them to be brought into
gear again at the proper time. This arrangement is provided at each side of the
apparatus and consists of a vertical cylinder 6 fixed to the frame A and containing a
spring which constantly maintains a downward pressure through the rod 7 upon the
slider 8 tending to keep it at the lower limit of its travel in the guide slot 9 in the
framing. This slider 8 projects by a sideway extension into the vertical groove of
one of the plates B2 so that as the embossing blocks come into the position illustrated
in Figure 2 in readiness to receive their forward traverse the pin C may strike the
said extension and raise the slider 8 against the resistance of the spring in the
cylinder 6. The raising of this slider lifts the tail ends of plate springs 10, 11 which
are secured thereto and the other ends of these springs are constrained to move
forward horizontally by the guide and guide pins 12. Studs 13 are fixed to the
underside of each segment wheel U in such a position that one end of the spring 11
being forced forward comes into contact with a stud and thereby pushes the wheel U
into gear with the rack d and with the wheel 1, with the result that the dies are
traversed horizontally. As soon as the pin C¹ in its horizontal travel leaves the
underside of the projection of the slider 8, the said slider is forced to its lowest position
by the spring in the cylinder 6, and the springs 10 and 11 resume their original
positions in readiness for another operation.
The stop-piece 14 is carried by and hinged upon the spring 10 and lies between
two guide pins 15, 16, these pins being so arranged that on the end of spring 10
commencing to travel forward horizontally as described the hinged stop-piece 14 is
brought into contact with the guide-pin 16 and its upper end thereby prevented from
travelling forward but its lower end is being carried forward horizontally by the
spring 10, and thus the hinged piece is caused to rotate on its hinge sliding downward
and forward between the two guide pins 15, 16, its upper end is lowered out of the
way of the stud 13 into the position illustrated in Figure 4 at the same moment that
the spring 11 pushes at the opposite side of the stud 13 to bring the segment wheel U

page_text: into gear with the racks d but as soon as the horizontal travel of the bed plate D³ and
its pin C¹ permits the slider 8 to fall the consequent horizontal withdrawal of the end
of the spring 10 causes the hinged stop piece 14 to rotate on its hinge and to slide
upward between the guide pins 15 and 16 into a vertical position so that the upper
edge of the stop piece may intercopt and stop the stud 13 and thereby prevent the
segment wheels U from making more than half a revolution.
I may use any other suitable device to bring the wheels U and 1 into gear.
I will now describe the means by which the apparatus driven, together with
the arrangement for varying the speed of withdrawal and return of the dies E E'
in accordance with the repeat in the pattern being embossed to enable different
lengths of repeat to be produced in the machine and prevent the length of pattern
last embossed from either overlapping or falling short of the length of pattern just
previously embossed, it being understood that the pulp or paper material from the
coucher roller passes through the apparatus at a constant speed. The shafts 2 are
geared with the coucher roll driving gear so that the speed of horizontal travel of the
blocks E E may always be the same as that of the pulp or paper material.
The mechanisin herein before described for controlling the rise and fall of the
embossing blocks may be driven by the well known double cone arrangement for
variable speed. 19 being the driving belt leading from the steam engine or other
prime mover and passing over a pulley on the shaft on which is fixed the upper
of the two cones 20, 2. The belt transmitting motion from one cone to the other
is marked 21, 22 being the bell shifter capable of being operated by the attendant.
by means of the rope 24 which passes around the pulleys 23 and 25 the pulley 25
being fixed upon a screw which causes the belt shifter to traverse the belt when
variations of the length of period between successive embossings are required. The
belt 26 (see Figure 1ª) transinits motion from the pulley 27 on the lower cone shaft
to a pulley 28 fixed to the shaft M³ on which are fixed spur wheels 29, which
transmit motion from that shaft to one of the segments 1 (the hinder one not seen
in Figure 1) by means of the gear wheels 30 and 31 (see Figure 2) and in order
that the movements of both the segments I may be synchronous, their shafts i į
are geared by the wheels 31, 32, 33 and 34 so that the rack bars G are operated
as described. To synchronize the movements of the rack bar G2 with those of the
rack bar G, each of the wheels 29 on the shaft M³ is geared by the wheels T¹ and T2
with a wheel 35 by which the segments I² are driven synchronously by the gear
wheels 36, 37, 38, 39 and 40 (see Figure 2).
1 will now describe the action of the machine starting with the assumption that
the pulp or paper 41 is receiving an impression, the embossing blocks E E2 being in
the position shown in Figure 2. The segment wheels U running at the same speed
as the pulp or other fabric to be treated are in gear with the racks d d of the
plates D D² and these plates with the blocks E E' are carried forward. The edges
of the grooves 2 for about one third of their length are slightly inclined towards the
blocks E E² so that as they are carried forward the pressure upon them is gradually
increased until they have passed through about one third of their travel when the
maximum pressure is reached and is maintained until the ends of the grooves a² are
reached and the said blocks are withdrawn respectively up and down the inclined
grooves x. During the horizontal traverse of the blocks the telescopic portions ƒƒ
of the rack bars G G³ are extended, and as the pins C₁ reach the ends of the
portions of the grooves the racks d d on the edges of the plates D D² will have
cleared the segment wheel U and the stud 13 on that wheel comes into contact with
the stop-piece 14 (Figures 4 and 6) and the wheel U prevented from being carried
further round by its momentum. When the plates D D2 cease to receive motion from
the wheel U the segment wheels R R2 engage with the toothed wheels P P² on the
shafts M M² and the rollers L L on those shafts wind in the chains k k² attached to
the bolts J J2 which chains draw the plates D D and blocks E E2 along the inclined
grooves x. In doing so the telescopic portions ff2 of the rack bars G G2 are first
pulled home (these telescopic portions being fitted in order that the compressing
links g g² may be caused always to take a proper bearing on the collars 43 of the

page_text: brackets F) then the rack bars G G2 still operated by the chains k k² are respectively
elevated and depressed until the pins C₁ of each plate (D D²) have arrived at the end
of the inclined grooves x in readiness to traverse the vertical portions of the said
grooves. The lower rack bar G2 is provided with a spring 42 of sufficient strength to
prevent its descent under the influence of gravity while its telescopic portions are
being returned as described. By the time these operations are concluded the segment
wheels 1 I will have reached the point of gearing into the racks h h on the bars G G2
which latter will immediately carry the plates D D² and blocks E E2 along the vertical
portions of the grooves into contact with the material 41 the segment wheels I I³
being by this time out of gear again with the racks h h². The upper plate D is
prevented from running away from its rack bar G and link g by the retarding
influence of the friction of the belt N³ upon the pulley N°. By the friction of the
belt Na tension is maintained sufficient to prevent the chain k² running freely off the
pulley L and hanging loosely about the machine. As the lower block E2 and its
plate D² arrive at the upper end of the vertical part of the grooves x and the upper
block E simultaneously arrives at the bottom the vertical portions of its grooves a one
of the pins C of the lower plate D² strikes and raises the slides 8 (Figures 4, 5 and 6)
which actuates the spring Il which in turn acting upon the pin 13 of the segment
wheel U forces it into gear with the wheel 1 and the racks d d of the bed plates D D²
which are traversed horizontally as described.
If in embossing or printing it is found that the blocks are either overlapping or not
quite reaching the work just previously done, by reason of the slight slipping of
any of the belts or because of any inequalities in the repeat of the pattern the
attendant in charge can immediately rectify this by operating the belt shifter 22
increasing or decreasing the speed of that portion of the machine which operates to
cause the withdrawal and return of the blocks E E².
This means for increasing or decreasing the speed of that part of the machine which
withdraws the blocks will allow of considerable variation in the length of repeat
in the patterns applied by the machine. It will be readily seen that the power of
varying the speed of this part of the machine is capable of allowing any length of
fabric (varying say for example from 21 inches to six feet) passing each time before
the blocks return to the material but if working short repeats it will be necessary to
decrease the length of the grooves a so that they have a less length in proportion to
the length of the blocks than they have in Figure 1.
When embossing pulp direct from the couch rolls 1 use one or more thick wet felts
to absorb the water pressed out, or I may use the arrangement described in the
Specification of my Patent No. 4227 of 1883 I prefer to bore holes through the
counter block E2 at those points where liquid is found to be driven in the operation of
embossing to allow of the escape of moisture from the material operated upon and
when desirable I also bore the upper block E in the same manner, but when I do this
I plug the said holes with porous material.
For these plugs I prefer to use clay and to mix it with napthalene or other
spirit then bake it to drive off the spirit taking care not to raise the temperature
too high. When the spirit has been driven off I form the clay into plugs of
suitable shape and secure them in the orifices in the block by cement or otherwise.
I have illustrated in Figure 7 several forms of plugs and modes of fixing them
in the blocks or dies but do not restrict myself thereto as many other shapes
may be used.
As shown at 1x the plug is conical and fitted in the die with its
smallest end to the face of the die, and to prevent the plug being forced out at
the back of the die a metal ring 2x is countersunk and fixed into the back of the
said die as shewn. As illustrated at 3× the plug is also conical in form and
cemented into the die with its largest end to the face thereof. As shewn at 4* a
hollow metal plug 5x is fitted and secured in a conical hole in the die and in
front of this metal plug the porous plug 4× is cemented in the hole in the die.
6 represents another form of plug it being partly conical and partly cylindrical
the smallest end of the cone being towards the face of the die and a metal ring being
countersunk in the back of the die as in the arrangement shown at 1*. 7* illustrates

page_text: another form of plug which may be of metal or other suitable substance pierced with
fine holes through its entire length, or if desired only through part of its length the
remainder of its length being pierced by one larger hole as shown, with which
the finer perforations communicate. These plugs may be provided with a screw thread
and be screwed into the holes in the block.
If I wish to emboss or otherwise act on unpressed or but lightly pressed paper
pulp or upon moistened paper already made or even upon dry paper or other material
by blocks or a block arranged according to my Invention but by an operation
distinct from the making of the paper I wind the paper on a roller or drum and
convey it to be acted upon by the block or blocks arranged to operate according to
my Invention.
It will be understood from the foregoing description that a printing block or
printing blocks or other equivalent devices which are required to act at intervals
upon a web of material in motion to emboss print or stamp the same can replace
the blocks E E2 illustrated.
When using the herein before described machine for printing I attach to it any
suitable arrangement for the inking or colouring the printing surface of the block,
and for printing or other purposes not requiring a counter die or block I may use a
fixed bed plate to receive the pressure when the block or other device is pressed on
to the fabric being treated. In order that this may be more fully understood I will
describe with reference to Figures 8 and 9 a suitable means for printing by this
machine. As previously described the block to which the printing surface is
attached has a continuous motion. After leaving the fabric being printed the
printing block E has an upward and diagonal motion and then descends in a vertical
direction onto the pressure receiving surface Ex. By the time the block Ę arrives
at the position indicated by dotted lines in Figure 8 the segment wheel 8* will have come
into gear with the rack teeth on the upper side of the sliding bar 9* and carried it
forward towards the printing block into the position shewn by the dotted lines. The
sliding bar 9× has pins or projections 10x 11* on its side which slide in the
groove 12× in the frame of the machine the upward inclination of which groove
causes the bar 9x when propelled by the segment wheel 8x to rise and bring into
contact with the printing surface a series of inking rollers 13× carried by the bar 9*.
The series of inking rollers 13× run freely in bearings on the bar 9x and in order
that these may receive the colour necessary to convey to the printing block I arrange
an endless web 14x of cloth, felt or other suitable material which receives its colour
by moving in contact with a roller 15× rotating in the colour contained in the
trough 16 and in order to regulate the amount of colour delivered to the web 14* I
fix a doctor 17* to bear against the roller 15 to remove excess of colour therefrom.
The web 14 passes around and receives its motion from the roller 18* and thence
around three rollers 19× and beneath two small rollers 20x which latter rollers are
provided with adjusting screws by means of which the two rollers may be moved
farther from each other for the purpose of tightening the web 14*. As the sliding
bar 9x with its inking roller 13× rises and falls in its forward and backward motions
I arrange the rollers 19× round which the web 14* passes to rise under the influence
of the pressure of the advancing inking rollers 13× and to ensure the rollers 19* and
the web. 14* returning to the level necessary to meet and colour the said inking
rollers when they advance the next time I fix one end of a spring 21x to the
frame 22× carrying the rollers 19× the opposite end of the spring being attached to
the frame of the machine. The frame carrying the rollers 19* consists of a rigid
triangular plate or bar 22× so that the three rollers move exactly in unison and keep
the same tension on the web 14*. To allow of their movement when pressed by the
advancing inking roller 13× I pivot the frame 22*, at the journals of two of the
rollers, to the frame of the machine by connecting bars or links 23× so that
the rollers receive a parallel motion. As soon as the pin 10x on the sliding bar 9×
reaches the uppermost end of the groove 12× the segment wheel will disengage the
teeth on the upper side of the bar 9x and the segment wheel 24* will engage the
teeth on the lower edge of the bar 9x and bring the bar back to its lowermost

position shown in the drawing where it will be stopped by the pin 11* reaching the
lower. end of the groove, 12x. The segment wheel, 8x will. then have reached
the point of contact with the upper toothed edge of the sliding bar 9* and the
motion hereinbefore described will be repeated.
In order that the several parts of the inking or coloring arrangement may. work
in unison with the movements of the block Emotion is imparted thereto from, the
shaft of the cone pulleys 20' hereinbefore referred to.
Having now particularly described and ascertained the nature of my said Inven-
tion and in what manner the same is to be performed, I declare that. what. 1
claim is
1. In apparatus for embossing, stamping, printing or the like at intervals on
paper or other fabrics or materials means whereby the embossing block or blocks or
other operating device or devices is or are caused to act on the fabric or material
whilst it is in motion the said blocks or devices being caused to travel in contact with
the fabric or material to the required distance and then to move out of contact
therewith and recede into position to effect the next operation at the required distance
on the fabric. or material from that at which the previous operation occurred the
apparatus being arranged so that it can be readily adapted for different lengths of
repeat of the pattern substantially as hereinbefore described.
2. In combination with the wet end of a paper making machine apparatus or
means adapted for manufacturing from paper making materials as a continuous
process variable lengths of repeat of pattern in decorative material panels architectural
ornaments and other embossed articles or articles in relief from the web or layer of
paper pulp as it is in motion on its way from the paper making machine substantially
as hereinbefore described.
3. In apparatus for embossing a material containing moisture holes in the embossing
block or blocks the said holes being plugged with a porous material substantially
as and for the purposes herein before described.
4. The combination of parts constituting an apparatus for embossing printing
stamping or the like paper or other fabric or material whilst in motion substantially
as hereinbefore described and illustrated in the accompanying drawings whether
the cone arrangement for varying speed for adjusting the repeats be used there-
with or not.
5. The combination with a printing block operating as hereinbefore described of
the arrangement of parts constituting apparatus for inking or colouring the surface
of the printing block for printing on paper or other fabric or material moving over a
pressure receiving surface substantially as hereinbefore described with reference to
Figures 8 and 9 of the accompanying drawings.
