Improvements in Machines for Printing Floor-cloth, Linoleum, and
the like.
I, CHARLES HERBERT SCOTT, of High Orchard Iron Works, Gloucester, in the
County of Gloucester, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention has reference to machines for printing floor cloth, linoleum and
the like by means of printing blocks and it has for objects to simplify and
cheapen the construction and improve the working of such machines. To this
end a printing machine according to this invention comprises a frame fitted with
a bed over which the floorcloth, linoleum or the like to be printed is traversed in
an intermittent or step by step manner by suitable means such as endless bands
to which an intermittent motion is imparted by suitable mechanism and which
are provided with spikes to or equivalent engage with and move the material to
be printed.
The printing blocks are arranged in sequence above the table and are pitched at
a distance apart equal to two or three times the width of the pattern to be printed.
Each printing block, which is or may be made in one piece, is fitted to a transverse
cast iron back (hereinafter called a pressure plate) provided at the ends with
trunnions that are connected by universal joints to slide blocks which are arranged
to work vertically in guides formed in standards fixed to each side of the machine,
and are supported by springs, the arrangement being such that one end of the
printing block can be lifted before the other and that the block can be oscillatel
without putting any undue friction on the machine.
Beneath the bed of the machine, and on the vertical centre line of each print-
ing block, is placed a transverse beam which is supported at its ends by springs
and is fitted with rollers against which work cams fixed on two longitudinal
shafts common to all the transverse beams. Each beam is guided in a suitable
manner at the ends so that the rotation of the shafts causes the cams thereon to
depress the beam which is raised by its springs when the cams allow this to ba
cone. To the trunnions of each pressure plate are pivoted arms or links the
lewer ends of which are adapted, as by bending or hooking, to be engaged with
and disengaged from the ends of the corresponding transverse beam below the
combined pressure plate and printing blocks, the arrangement being such that
when the arms are permitted to hang vertically the pressure plate will be con-
nected to the transverse beam so that the former will move up and down with
the latter, but by moving the arms to one side of the vertical line, as by hand
levers, the pressure plate will be disconnected from the transverse beam so that
it and the corresponding printing block will not then be operated by the latter
but will remain at rest. To enable the connection between the lower end of
each pivotted arm and the corresponding transverse beam to be adjusted verti-
cally, the abutting parts may be carried by vertically adjustable screws.
Colour is applied to the lower side of each printing block by means of a roller
mounted in a colour or tiering box adapted to be suitably reciprocated below the
said block. The several tiering boxes are reciprocated by longitudinal rods or
bars that are arranged at the sides of the machine and are themselves reciprocated
by suitable means such as cams and connecting mechanism such as levers and
slide blocks, the connection between each tiering box and the slide rods or bars

page_text: being effected through disengaging gear such as levers and catches so constructed
and arranged that should any printing block by accident be down on the material
being printed when the corresponding tiering box advances towards it, such box
will be disengaged from the slide rods or bars and come to rest, thus obviating
damage.
To enable the momentum of the colour box operating mechanism when moving
in either direction to be taken up and utilized to assist the cams to afterwards
move the boxes in the opposite direction, there is or are provided in connection
with such operating mechanism, one or more energy accumulators which act to
absorb the momentum of the said mechanism and colour boxes thus bringing
them to rest without shock and to give out this stored energy to assist in moving
the parts in the opposite direction on the return stroke. A device suitable for
this purpose comprises a coiled spring arranged between a piston connected by a
rod to a link pivoted to the bed or frame of the machine and the closed free end
of a cylinder in which the piston works and the other end of which is pivoted to
a moving part such as one of the slide rods or bars.
To enable any one of the printing blocks to be put and held out of action so
that other printing blocks may make two or more downstrokes and impressions
for one stroke and impression of another block or blocks the several hand levers
used for moving the pivoted arms and connecting and disconnecting the pressure
plates with the transverse beams below them, are each furnished with an extra
arm that is adapted to be engaged with a sleeve or collar on a longitudinal shaft
that is arranged to be moved backwards and forwards by suitable means, such
as a cam. Each collar is so mounted on its shaft that it can be readily thrown
in and out of gear with its corresponding lever, the arrangement being such that
when one or more collars is or are thrown into gear with its or their lever or
levers, the corresponding printing block or blocks will be disconnected from its or
their transverse beam and will remain at rest whilst the remaining block or
blocks are making another downstroke. In this way some of the printing blocks
can be caused to make two or more impression strokes for each impression stroke
of the others.
To prevent the printing blocks that remain idle from receiving fresh colour
from their tiering boxes, the upper ends of each pair of arms pivoted to the trun-
nions of a pressure plate are adapted to abut against stops that are carried by
the standards in which the slide blocks of the pressure plate work and which are
each formed with a stepped lower surface, the arrangement being such that
when the arms are in the vertical or operative attitude and the printing blocks
are at the end of their upstroke, the upper ends of the arms, or projections thereon,
will bear against the lower portion of the stepped surface of the stops and hold
the printing blocks in the proper position to receive colour from the tiering roller
of its colour-box, but when the arms are moved to one side of the vertical, i.e.,
their inoperative attitude, the upper ends of the arms, or the projections thereon,
are brought opposite to the higher portion of the stepped surfaces of the stops so
that the printing block can be raised a little higher by its springs and held out
of contact with the tiering roller of the corresponding colour box which then
consequently moves idly. The above mentioned stops may be made vertically
adjustable for regulating the height of the printing blocks above their colour
boxes.
The feeding mechanism for intermittently moving the floor cloth, linoleum on
like material forward, is or may be operated by a double cam one portion of which
moves the material forward one step for each stroke of the printing blocks and
the other moves it forward for every alternate stroke of the blocks. Suitable
means operated by a handle or otherwise is provided for throwing either cam or
part thereof into the operative or inoperative position at will. It will thus be
understood that the machine can be made to print either once with all the blocks
or twice or more with any number of the blocks, as may be desired, for each
forward movement of the material being printed, and that the necessary motions

page_text: are effected automatically by the machine when the requisite parts have been put
into or out of gear.
Also that should, by accident, any one of the printing blocks
not print properly the whole of the other blocks and the feeding mechanism can
be thrown out of gear and the block then brought down again so as to rectify any
error that has been made in the printing without interfering in any way with
sequence of movements of the machines.
To reduce the weight and consequently the momentum of the colour box and
also liability of the colour splashing over the sides of the box, the said box may
be made of sheet metal, stamped it may be to shape, and provided with an over-
hanging upper edge on its inner -side.
In this colour box instead of driving the colour or tiering roller by means of
one or more gear wheels working in a rack on the frame of the machine as hereto-
fore usual, I prefer to drive it by means of one or more metal rollers keyed on
the end or ends of the roller shaft, which is driven from a plane surface on the
bed of the machine by means of an intermediate wheel or wheels covered with
india rubber or other equivalent soft substance. The intermediate wheel or wheels
is or are provided with an adjustment so that it or they can be pressed between
the plane surface of the bed and the metal wheel or wheels on the tiering roller
shaft so as to produce sufficient friction for transmitting the necessary driving
power. I find that this motion is smoother in working and consequently deposits
the colour on the surface of the printing block with greater regularity than has
heretofore been usual.
The colour or tiering roller is fitted with a doctor (or doctors) to regulate the
amount of colour deposited on it. With a view of regulating the amount of
colour put on the sides or middle of the roller, I sometimes make this doctor of
a thin steel bar constructed in such a way that it can be shortened horizontally,
'so as to make the bar assume a curved form. When therefore the bar is
screwed up so as to curve it, its centre moves away from the centre of the tiering
roller, and the space between it and the tiering roller, is therefore greater, so
that more colour is deposited on the centre of the tiering roller than before. By
reversing this action I am enabled to decrease the amount of colour deposited on
the middle in reference to that which is deposited on the sides. By this means
I am able to deposit an even amount of colour on the tiering roller although this
roller may not be perfectly straight or cylindrical. The whole of this improved
doctor is arranged to be set up to the roller without interfering with the adjust-
ment before mentioned.
The machine is or may be fitted with its own engine which drives the longi-
tudinal cam shafts hereinbefore referred to, preferably through worm-gearing, the
only other gear wheels necessary being those used for operating the colour box
reciprocating mechanism and the feeding mechanism which is or may be done
from the said longitudinal shafts,
The machine is or may also be mounted on travelling wheels for convenience
of working in the drying or hanging rooms usually employed for drying printed
cloth.
Improvements in Machines for Printing Floor-cloth, Linoleum, and
the like.
I, CILARLES HERBERT SCOTT, of High Orchard Iron Works, Gloucester, in the
County of Gloucester, Engineer, do hereby declare the nature of this invention

page_text: and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
This invention has reference to machines for printing floor cloth, linoleum and
the like by means of printing blocks and it has for objects to simplify and
cheapen the construction and improve the working of such machines, as I shall
now describe with reference to the accompanying drawings wherein Figs. 1 and 1*
show in side elevation, Figs. 2 and 2ª in plan, and Fig. 3 in cross section, partly
on the line xx and partly on the line y y of Fig. 1, a printing machine embodying
my invention. Fig. 4 is a part side elevation showing the printing lever disen-
gaging mechanism. Fig. 5 is a longitudinal section showing tiering mechanism
with an energy accumulator. Fig. 6 is a longitudinal section, Fig. 7 a cross
section partly in end elevation, and Fig. 8 a part plan, showing an improved con-
struction of color box with improved driving mechanism for the tiering roller
thereof. Fig. 9 shows the tiering roller with an improved construction of doctor
therefor. The figures are drawn to different scales.
The printing machine comprises a frame 1 fitted with a bed or table 2 over
which the floor-cloth, linoleum or the like to be printed, is traversed in an inter-
mittent or step by step manner by suitable means such as bands 3 to which an
intermittent motion is imparted by suitable mechanism and which are provided
with spikes or equivalent to engage with and move the material to be printed.
The printing blocks 4 are arranged in sequence above the table 2 and are pitched
at a distance apart equal to two or three times the width of the pattern to be
printed. Each printing block (which is or may be made in one piece) is fitted
to a transverse cast iron back 5 (hereinafter called a pressure plate) provided at
the ends with trunnions 6 that are connected through universal joints to slide
blocks which are arranged to work vertically in guideways 8 formed in stan-
dards 9 fixed to each side of the machine, and are supported by springs 10, the
arrangement being such that one end of the printing block 4 can be moved
vertically to a small extent independently of the other end and that the said
block can be oscillated without putting any undue friction on the machine. In
the example shown each trunnion 6 is mounted to turn in a bearing 6 which is
mounted to turn in the corresponding slide block 7 about an axis at right angles
to that of the trunnion, so that the trunnion can move about axes at right angles
to one another. By the arrangement described the printing block can be lowered
and lifted in such a way that one corner thereof can, as hereinafter described,
be caused to touch the material to be printed before the remainder and can iso
be caused to leave the material first whereby better printing is ensured and
smudging of the colour by the block, when being lifted off, prevented.
Beneath the bed of the machine, and on the vertical centre line of each printing
block 4, is placed a transverse beam 11 which is supported at its ends by springs 12
and is fitted with rollers 13 against which work cams 14 fixed on two longitudinal
shafts 15 common to all the transverse beams 11. Each beam 11 is guided in a
suitable manner at the ends, so that the rotation of the shafts 15 causes the cams 14
thereon to depress the beam which is afterwards raised by its springs 12 when the
cams allow this to be done. To the trunnions 6 of each pressure plate 5 are pivoted
arms or links 16 the lower ends of which are adapted, as by bending or hooking,
to be engaged with and disengaged from the ends of the corresponding transverse
beam 11 below the combined pressure plate 5 and printing block 4, the arrange-
ment being such that when the arms 16 are permitted to hang vertically, the
pressure plate 5 will be connected to the transverse beam 11 so that the former
will move up and down with the latter, but by moving the arms 16, to one side of
the vertical line, as by a hand lever 17, the pressure plate 5 will be disconnected
from the transverse beam 11 below it so that it and the corresponding printing
Block 4 will not then be operated by the said beam but will remain at rest.
enable the connection between the lower end of each pivoted arm 16 and the
corresponding transverse beam to be adjusted vertically, the abutting parts 16"
and 11 may be carried by vertically adjustable screw 16° and 11 respectively.
To

page_text: The hand lever 17 connected to an arm 16 on one side of the machine is fixed
upon one end of a transverse shaft the other end of which is suitably connected
to the arm 16 at the opposite side of the machine, so that both arms work together.
To cause each printing block to first bear at one corner upon the material
being printed, one of the cams 14 of each pair is set slightly in advance of the
other, and to one of the trunnions 6 of the printing block is fixed a rod 6* that
works through a fixed guide 6b, has a conical or reduced part 6, and is pressed
sideways by a roller 6 carried by a bracket 6. The roller G presses on the
extension of the rod 6 which consists of a steel spring, which bends to one side
until the reduced part 6 enters the guide Gb. The arrangement is such that one
end of the printing block will be caused to descend slightly in advance of the
other and when the block descends sufficiently to bring the conical or reduced
part 6° into the guide 6b, the rod 6 will be moved to one side by the roller 6d,
the combined effect being to cause one corner of the printing block to first bear
upon the material, after which the block adjusts itself evenly over the printing
material. Similarly on the upward stroke of the block, one corner of the block
will be the first to leave the material.
Colour is applied to the lower side of each printing block 4 by means of
tiering roller 18" mounted in a colour or tiering box 18 arranged to travel on
ways 19 on the bed 2 and adapted to be suitably reciprocated below the said
block. The several tiering boxes 18 are reciprocated by longitudinal rods or
bars 20 (Fig. 3) that are arranged at the sides of the machine and are themselves
reciprocated by suitable means which, in the example shown (see Fig. 5) com-
prises one or more rotary cams 21 arranged, or each arranged, to act upon one
arm of a bent lever 22 that is pivoted at 22" and has its other arm connected by
a link 22 to a lever arm 22° fixed upon a cross shaft 22d to which are fixed
arms 22° each of which is connected by a link 22 to a lug 22 on the correspond-
ing rod or bar 20. The cam or cams 21 is or are fixed upon a cross shaft 21"
which is driven from one or both of the longitudinal shafts 15, as for example
through gearing 21b. The connection between each tiering box 18 and the slide
rods or bars 20 is effected through disengaging gear such as a pair of bell crank
levers 23 one arm of each of which is acted upon by a spiral spring 24 and has
its other arm shaped to form a catch 23" (Figs. 6 and 8) that is adapted to engage
with a recessed block 23b on the adjacent rod or bar 20, the arrangement as will
be seen being such that should a printing block 4 by accident be down on the
material being printed when the corresponding tiering box 18 advances towards
it, such box will be disengaged from the slide rods or bars and come to rest, thus
obviating damage.
A
To enable the momentum of the colour box operating mechanism when moving
in either direction to be taken up and utilized to assist the cams 21 to after-
wards move the boxes in the opposite direction, there is or are provided in con-
nection with such operating mechanism, one or more energy accumulators which
acts or act to absorb the momentum of the said mechanism and colour boxes
and so bring them to rest without shock and to give out this stored energy to
assist in moving the parts in the opposite direction on the return stroke.
device suitable for this purpose is shown in Fig. 5 and comprises a coiled spring 25
which is arranged between a piston 26 connected by a rod 27 to a link 28 pivoted
on the shaft 22d, and the closed free end of a cylinder 29 in which the piston
works and the other end of which is pivoted at 29° to a moving part 20° in con-
nection with one of the slide rods or bars 20. As will be seen this construction
of energy accumulator will act to absorb the momentum of the said colour box
operating mechanism when moving in each direction, and to give out energy
when the said mechanism commences to move in the opposite direction.
To enable any one of the printing blocks 4 to be put and held out of action,
so that one or some of the printing blocks 4 may make two or more downstrokes
and impressions for one stroke and impression of another block or blocks, the

page_text: several hand levers 17 used for moving the pivoted arms 16 for the purpose of
connecting the pressure plates 5 to and disconnecting them from, the transverse
beams 11 below, are each furnished with an extra arm 17" that is adapted to be
'engaged with a sleeve 30 on a longitudinal shaft 31 which is arranged to be
'moved backwards and forwards by suitable means, such as a cam 32, and a lever 33
(Figs. 1 and 4) which is oscillated by the said cam and is jointed to the said shaft.
Each sleeve 30 is arranged between collars 31° on the shaft so as to reciprocate
with the shaft but can be partly turned on the shaft, which it fits tightly, so that
it can be readily thrown in and out of gear with its corresponding lever 17, 17ª,
the arrangement being such that when one or more sleeves is or are thrown into
gear with its or their lever or levers 17, 17, the corresponding printing block or
blocks 4 will be disconnected from its or their transverse beam 11 and will remain
at rest whilst the remaining block or blocks is or are making another downstroke.
In connection with the mechanism for forwarding the cloth, there is provided a
cam which moves the feeding pawl out of gear in such a manner, as hereinafter
described, that the cloth will be rendered stationary during the second stroke,
or succeeding strokes, of one or more blocks when it or they is or are intended
to make two or more impressions. Each hand lever 17, 17 may be fixed to the
frame of the machine by a pin so as to hold the corresponding pair of arms 16
in the operative or inoperative position at will. When so fixed, the correspond-
ing sleeve 30 should, of course, be disconnected from it.
To prevent the printing blocks 4 that remain idle from receiving fresh colour
from their tiering boxes, the upper ends of each pair of arms 16 pivoted to the
trunnions 6 of a pressure plate 5, are adapted to abut against stops 34 (Figs. 1
and 1) that are carried by the standards 9 in which the slide blocks of the
pressure plate work and which are each formed with a stepped lower surface, as
shown, the arrangement being such that when the pair of arms 16 are in the
vertical or operative attitude and the corresponding printing block 4 is at the
end of its upstroke, the upper ends of projections 16 on such arms will bear
against the lower portions 34 of the stepped surfaces of the stops 34 and hold;
the printing block in the proper position to receive colour from the tiering
roller 18 of its colour box 18, but when the arms 16 are moved to one side of
the vertical, i.e. their inoperative attitude, the projections 16 thereon will be
brought opposite to the higher portions 34 of the stepped surfaces of the stops 34
so that the printing block 4 can be raised a little higher by its springs 10 and
held out of contact with the tiering roller 18 of the corresponding colour box
which then consequently moves idly. The stops 34 may be made vertically
adjustable as for example by screws 35 and hand wheels 36, for the purpose of
regulating the height of the printing blocks 4 above their colour boxes 18.
The feeding mechanism for intermittently moving the bands 3 with floor cloth,
linoleum or like material in a forward direction, is or may be controlled by two
cams 35, 35, one of which viz. 35, serves, as for example through a lever 36,
link 37, arm 38, ratchet tooth 39 and ratchet wheel 39" to move the bands and
material forward one step for each stroke of the printing blocks 4, whilst the
other cam 35° serves, as for example through a lever 40, link 41, lever arm 42
and link 42ª, to hold the ratchet tooth 39 out of engagement with the ratchet
wheel 39° when the material being printed is to receive two successive impressions
from one or some of the printing blocks.
Suitable means operated by a handle or otherwise are provided for throwing
each of the cams 21, 32, 35 and 35* into the operative or inoperative position at
will. It will thus be understood that the machine can be made to print either
once with all the blocks, or twice or more times with any number of the blocks,
as may be desired, for each forward movement of the material being printed,
and that the necessary motions are effected automatically by the machine when
the requisite parts have been put into or out of gear. Also that should, by
accident, any one of the printing blocks 4 not print properly, the whole of the
other blocks and the feeding mechanism can be thrown out of gear and the block

page_text: then brought down again so as to rectify any error that has been made in the
printing without interfering in any way with the sequence of movements of the
machine.
To reduce the weight and consequently the momentum of each colour box 18
and also liability of the colour splashing over the sides of the box, the said box
may be made of sheet metal, stamped it may be to shape, and provided with an
overhanging upper edge 18 on its inner side, as shown in Fig. 6. In this colour
box instead of driving the colour or tiering roller 18 by means of one or more
gear wheels working in a rack on the frame of the machine, as heretofore usual,
it may be driven by means of metal rollers 18 keyed one on each end of the
roller shaft 18, and driven from a plane surface 19 on the bed of the machina
by means of intermediate wheels 18° covered with india rubber or other equi-
valent soft substance. The intermediate wheels 18° are adjustably mounted, as
on adjustable arms 18', so that they can be pressed between the plane surface
of the bed 2 and the metal wheels 18 on the tiering roller shaft 18° so as to pro-
duce sufficient friction for transmitting the necessary driving power. I find that
by this construction the tiering roller 18ª works more smoothly and consequently
deposits the colour on the surface of the printing block with greater regularity
than has heretofore been usual. Instead of driving each end of the tiering roller
as described, one end only may be so driven. The colour or tiering roller 18"
is fitted with one or more doctors 188 to regulate the amount of colour deposited
on it.
With a view of regulating the amount of colour put on the sides or middle
of the roller, I sometimes make the doctor or each doctor 18% of a thin steel bar
constructed in such a way as shown for example in Fig. 9, that it can be shortened
horizontally by means of one or more screws 18h, so as to make the bar assume
a more or less curved form as shown in dotted lines. The bar is not made quite
straight so that in its straightest position it is slightly curved, being a little
higher in the middle, the action of the screw being to increase this curve more or
less. The surface of the bar is therefore made to such a curve, that in the middle
position it will be equidistant from the roller; at the lowest position it will be
nearer the roller at the middle than at the sides; at the highest position it will
be nearer the roller at the sides than at the middle, so that the relative quantity
of colours deposited by the ends or middle of the roller, can be adjusted at will.
By this means the relative amounts of colour put on the middle and ends of the
tiering roller can be varied. The whole of this improved doctor is arranged so
that it can be set up to the roller without interfering with the adjustment
herein before mentioned.
The machine is or may be fitted with its own engine 43 which drives the longi-
tudinal cam shafts 15 herein before referred to, preferably through a cross shaft 43"
and worm-gearing, the only other gear wheels employed being those used for
operating the colour box reciprocating mechanism and the feeding mechanism
which may, as in the example shown, be done from the said longitudinal shafts.
The machine may be mounted on travelling wheels 44 arranged to run on
rails 44 for convenience of working in the drying or hanging rooms usually
employed for drying printed cloth.
Having now particularly described and ascertained the nature of the said in-
vention and in what manner the same is to be performed I declare that what I
claim is:-

ment being such that the printing blocks can be caused to bear at one part before
another and can afterwards adjust themselves evenly on the material being
