Improvements in Apparatus for Printing Floor Oloths and
other Fabrios.
I EDWARD WEBB of 62 Great Cheetham Street Lower Broughton Manchester
in the County of Lancaster Manager, do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to the apparatus for printing floor cloths and other fabrics,
for which Letters Patent No. 9531, dated 6th July 1887 were granted to me, and
the object of my present invention is to improve the mechanism for supplying the
various colors to their respective blocks.
For this purpose I mount a carriage of suitable form and dimensions moving
above the block printing roller upon wheels or pulleys on fixed rails suitably
supported.
This carriage is provided with a number of endless bands of canvas or other
suitable material stretched upon revolving rollers, and running parallel with the
printing blocks and with each other. Each of these endless bands is furnished
with color by a roller running in a color-trough and is "doctored" by a suitable
doctor plate.
As each block is brought uppermost by the revolution of the printing roller it is
raised against one of the endless bands furnished with its appropriate color (as
above described) and preferably backed by a backing plate or pad resting upon the
said band between the two stretching rollers.
It is preferable so to arrange the colors for these bands that when printing for
example in six colors the third band supplies color to No. 1 block, the fifth band
supplies No. 2 block, and the sixth band No. 3 block. The carriage then returns
and the 4th band supplies No. 4 block, the second band No. 5 block, and the first
band No. 6 block.
The motion of the carriage to bring the color furnishing bands into their proper
positions as above described is obtained by preference as follows:-The carriage is
provided at one end with a long horizontal frame supporting on one side three vertical
grooved plates or slides two being longer than the third. A crank pin or bowl
upon a large spur wheel works alternately in each of the two longer slides or
grooves, the throw of the crank and the length of the groove being such as to move
the carriage a distance equal to two of the furnishing bands to supply the colors in
the order above described to the first and second blocks. A crank pin or bowl also
on the above named spur wheel (but with a shorter throw) then engages in the
shorter slide or groove and moves the carriage forwards for a shorter distance as
described to furnish color to the third block.
The shaft upon which the spur wheel is fixed is then moved lengthways dis-
engaging these crank pins or bowls from the grooves and bringing similar pins or
bowls on a spur wheel at the other side of the horizontal frame (but revolving in
the opposite direction) into position to engage in vertical grooves or slides on that
side of the frame so as to reverse the motion of the carriage for supplying the
remaining three blocks with color; the above shaft is then again moved lengthways
to bring the first named crank pins or bowls into action, and so on.
The crank wheels are or may be driven by pinions on a main shaft the one
direct and the other through an intermediate carrier pinion. The sliding motion
of the shaft on which these crank wheels are mounted is obtained by a grooved
boss thereon, in which engages a pin or bowl on a lever actuated by a cam
on a shaft driven by a worm wheel and a worm upon the main shaft above
described.

page_text: In order to prevent the frame from over-running its proper position at each
partial revolution of the printing roller, 1 provide a locking pin actuated by
suitable levers and a cam upon the above named sliding shaft. This pin is
lowered at each motion of the carriage so as to engage in notches or slots in the
horizontal frame and so arrest any tendency to over run the exact position of the
furnishing band above.its block.
The driving rollers of the color furnishing bands are actuated by spur gearing
from a long shaft revolving in suitable bearings on the carriage, and this shaft is
driven by bevil gearing from a short transverse shaft, on which is a pulley or
drum round which is wound a rope or chain fixed at each end to the supporting
framework of the machine and thus as the carriage is moved the furnishing bands
are caused to travel over their rollers, and by running in contact with the color
furnishing rollers as before described, will be evenly supplied with color ready to
furnish their respective blocks which they will do more regularly and evenly than
any other color furnishing device now in use.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Printing Floor Oloths and
other Fabrics.
I EDWARD WEBB of 62 Great Cheetham Street Lower Broughton Manchester
in the County of Lancaster, Manager, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement:―
This invention relates to the apparatus for printing floor cloths and other fabrics
for which Letters Patent No. 9531 dated 6th July 1887 were granted to me, and
-the object of my present invention is principally to improve the mechanism for
supplying the various colors to their respective blocks.
The nature of my said invention and the manner in which the same is to be
:performed or carried into practical effect will be readily understood on reference
to the three sheets of drawings hereunto annexed and the following explanation
- thereof.
On Sheet of the drawings Fig. 1 is a side elevation of the driving end of the
-machine, and Fig. 2 is a plan view of the same.
On Sheet 2 of the drawings Fig. 3 is a side elevation of the printing end of the
-machine, Fig. 4 is an elevation of the same partly in section and with the frame
-removed and Fig. 5 is a partial front view.
On Sheet 3 Fig. 6 is a vertical transverse section taken through about the
line A-B in Fig. 1.
The general construction of the printing portion of the machine is seen best at
Figs. 3 and 4 Sheet 2. It consists mainly of a frame a supporting in suitable
bearings a crank shaft b which by means of connecting rods e gives an upward and
downward-motion to the axle d of the printing roller e which is made with six faces
each fitted with a printing block f. At one end of this roller is a plate g (see
Fig. 3) fitted with six studs h each of which in succession as the roller rises comes
into contact with a catch i which causes the roller each time it rises to make
one sixth-of a-revolution so as to bring each of the six blocks f in succession into
-working position.
The Hoor cloth or other material to be printed is wound upon a batch roller k
-and-fed forward-intermittently by feed rollers over the table m where the printing
takes place.
For supplying the various colors to the blocks fas required I mount a carriagem

page_text: of suitable form and dimensions above the block-printing roller e, moving upon
wheels or pulleys o on fixed rails p suitably supported.
This carriage n is provided with a number of endless bands of canvas or other
suitable material stretched upon revolving rollers and running transversely across
the machine parallel to the printing blocks and to each other.
r
Each of these endless bands q is furnished with color by a rollers running
in a color trought and is "doctored" by a suitable doctor plate as is well
understood.
As each block is brought uppermost by the revolution of the printing roller e
it is raised up by the crank-shaft b against one of the endless bands furnished
with its appropriate color (as above described) and preferably backed by a backing
plate or "pad" u resting upon the said band 9 between the two stretching
rollers r.
It is preferable so to arrange the colors for these bands g that when printing,
for example, in six colors as the carriage moves forward the third band supplies
color to the first block, the fifth band supplies the second block, and the sixth
band the third block. As the carriage returns the fourth band supplies the
fourth block, the second band the fifth block, and the first band the sixth
block.

into their
The motion of the carriage n to bring the color furnishing bands
proper positions as above described is obtained by preference as follows: the
carriage n is provided at one end (see Figs 1 and 2) with a long horizontal frame v
supporting on each side three vertical grooved plates or slides two two of which are
longer than the third wo and the latter also projects from the frame further than
the former. A crank pin or bowl upon a large spur wheel y works alternately in
each of the two longer slides or grooves w as the wheel y revolves, the throw of the
crank and the length of the grooves being such as to move the carriage na
distance equal to two of the furnishing bands 9 to supply the colors in the order
above described to the first and second blocks. A crank pin or bowl a¹ also upon
the spur wheel y (but with a shorter throw) then engages in the shorter slide or
groove and moves the carriage forwards for a shorter distance as described, to
furnish color to the third block. The shaft z upon which the spur wheel y ig
fixed is then moved lengthways disengaging these crank pins or bowls from the
grooves w, to and bringing similar pins or bowls and on a spur wheel y¹ at
the other side of the horizontal frame (but revolving in the opposite direction)
into position to engage in vertical grooves or slides w³ ³ on that side of the frame
so as to reverse the motion of the carriage n for supplying the remaining three
blocks with color; the shafts are then moved again lengthwise to bring the first
named crank pins or bowls and .' into action and so on.
The crank wheels y and y' are driven by pinions 1 (see Fig. 6) one on a counter
shaft 2 driving direct and the other through a pair of intermediate carrier pinions 3
and a second shaft 4. The counter shaft 2 is driven by bevil gear 5 from the main
driving shaft 6.
The sliding motions of the shafts z and z¹ on which the crank wheels y and y¹
are mounted is obtained by grooved bosses 7 on the ends thereof into which
engage pins 8 on levers which are connected together by a link 10 and actuated
by a cam 11, on a shaft 12 which is driven by a worm wheel 13 and a worm 14 on
the counter-shaft 2.
ย
In order to prevent the frame from over running its proper position at each
revolution of the printing roller e I provide a locking pin 15 (see detached view
Fig. 14) actuated by a suitable lever 16 and a cam 17 upon the above named sliding
shaft z which carries the wheel y. This pin 15 is lowered at each motion of the
carriage n so as to engage in notches 18 in the horizontal frame v (see also Figs. 1
and 2) and so arrest any tendency to over run the exact position of the furnishing
q above its block f.
band
The driving rollers of the color furnishing bands 9 are actuated by spur
gearing 19 from a long shaft 20 revolving in suitable bearings on the carriage n

page_text: and this shaft is driven by bevil gearing 21 from a short transverse shaft 22 on
which is a pulley or drum 23 round which is wound a rope or chain 24 fixed at
each end to the supporting frame-work of the machine, and thus as the carriage n
is moved the furnishing bands g are caused to travel over their rollers r, and by
running in contact with the furnishing rollers as above described will be evenly
supplied with color ready to furnish their respective blocks f which they will do
more regularly and evenly than any other color furnishing device now in use.
The bevil gear 21 is provided with a reversing clutch 21* actuated by the
carriage n at each end of its traverse so that the bands g will always be driven in
the same direction whether the carriage is going out or returning.
In order to hold the edges of the furnishing bands g close against the pads whilst
the blocks are receiving their color I attach to the revolving plate g (see Fig. 3)
a disc 25 carrying six bars 26 which in succession as the printing roller e rises
come against an incline 26* at the upper end of a lever 27 which is connected by a
link 28 and lever 29 to a rocking bar 30, another lever 31 on which (see Fig. 4) is
connected by two bent links 32, to spring levers 33 carrying light rods or cross
bars which as the printing roller e rises press the edges of the bands 9 upwards
against the pad u.
I would here observe that although for the sake of illustration I have described
my invention as applied to a machine having a six sided roller, it will be evident
that my invention is equally applicable to machines of the same class having a
greater or less number of sides or faces.
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 I
claim is :-
First. The general construction and arrangement of parts constituting the
improved apparatus for printing floor-cloths and other fabrics substantially as
hereinbefore described and illustrated by the drawings annexed, and
Secondly. I claim particularly the construction and arrangement of the
mechanism for supplying the various colors to their respective blocks substantially
as hereinbefore described and illustrated by the said drawings.
