Improvements in Rollers for Printing upon Textile Fabrics and
other Materials, and Specially Applicable for Printing Trade
Marks and other Marks and Devices upon Piece Goods.
I WILLIAM JAMES CRIGHTON of Great Marlborough Street, Manchester, in the
County of Lancaster, Manager, do hereby declare the nature of this Invention to be
as follows:-
:-
For
My said Invention relates to rollers for printing upon textile fabrics and other
materials and particularly to rollers for printing trade marks and other devices,
numbers, names and the like upon folded piece goods, for example such rollers as
are used in a trade mark printing machine for which Letters Patent were granted
to John Duxbury on the 6th day of December 1879, No. 4998. In printing trade
marks upon such goods it is frequently necessary to vary names, numbers and other
signs accompanying the trade mark. Under present arrangements such additional
imprints have to be added by separate means after the chief mark is impressed by
the copper or other roller, for it will be evident that to engrave or otherwise
produce such additional matter upon the roller would render it fit for use only in
printing such goods as are to bear that particular combination of marks. According
to my invention I construct the copper or other printing roller in such a manner
that I can alter or remove parts thereof, which parts are engraved with or otherwise
carry the numbers, names or designs which accompany the main trade mark and
which I may desire from time to time to alter or dispense with. With this object
the roller is composed of a central core or mandril upon which I fix or slip shells,
rings or thimbles of copper or other suitable metal or material engraved with or
otherwise having or carrying a surface capable of printing the trade mark and
other interchangable combination marks, numbers, designs and the like.
example in constructing a roller in accordance with my invention I first provide
the said central core or mandril turned and finished on its periphery. The respective
shells or rings engraved or etched with sunk lines or having the design in relief
are then fixed or slipped upon the core or mandril at the proper intervals apart,
separating blanks or rings being placed between the shells or rings to fill up the
intervening: spaces. Compressing nuts at the ends of the mandril or other means
are provided to bind the whole firmly together so that a homogeneous roller is.
produced presenting the required combination of marks upon its surface. For
example the central part of the roller would be occupied by the shell or ring
bearing the main or central trade mark while on either or both sides the shells or
rings bearing the combination or interchangeable marks would appear. To change
the combination it is only necessary to remove the shell or shells bearing the
particulars which it is required to alter, and to replace it or them by another or
by others engraved with or carrying different matter or designs and thus a change
in the combination is effected with but little trouble or cost. The shells or rings
may either be split and applied in halves or portions to the core or mandril or they
may be slipped on from the ends of the mandril. When applied in halves or
portions we prefer to form the ends of the shells or rings with inciined or checked
dges which slope or lie beneath similar inclined or checked edges formed on the
lanks between, so that when the whole roller is compressed by the nuts or other
neans at the end of the core or mandril the shells or rings are securely held in
osition. The colour trough for supplying colour to the roller may be divided
nto compartments opposite to the respective shells or rings and filled with different
olours so as to print the different parts of the combination with different colours
such should be desired.

page_text: Although in the foregoing description I have referred to my invention as being
more particularly applicable to rollers used in apparatus for printing trade marks
upon folded piece goods it will be understood that I do not limit myself to this as
such rollers may be used to print in one or more colours upon other materials such
as calico and paper. My improved roller might be applied to existing machines for
printing upon such materials. It will also be understood that the herein before
referred to interchangable printing rings or shells may be made of copper or of
any other metal or material capable of being used for printing purposes.
The
designs may be engraved or etched in sunk lines on the said rings or shells or
the designs may be in relief or may be produced in any other manner. When the
shells or rings are split they may be applied in two, three or more parts, and in
such a case
might arrange that only one of the said parts would carry the design
the other part or parts being blanks or filling up pieces of the same or of a different
or less valuable metal or material than the portion carrying the design. The
improved roller might revolve partly in the colour trough, or colour might be
transferred by suitable means to the roller from the colour receptacle or receptacles.

COMPLETE SPECIFICATION.
Improvements in Rollers for Printing upon Textile Fabrics and
other Materials, and Specially Applicable for Printing Trade
Marks and other Marks and Devices upon Piece Goods.
I WILLIAM JAMES CRIGHTON of Great Marlborough Street, Manchester, in the
County of Lancaster, Manager, 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 and accompanying drawings
My said Invention relates to rollers for printing upon textile fabrics and other
materials and particularly to rollers for printing trade marks and other devices,
numbers, names and the like upon folded piece goods, for example such rollers as
are used in a trade mark printing machine for which Letters Patent were granted
to John Duxbury on the 6th day of December 1879 No. 4998. In printing trade
marks upon such goods it is frequently necessary to vary names, numbers and other
signs accompanying the trade mark. "Under present arrangements such additional
imprints have to be added by separate means after the chief mark is impressed by
the copper or other roller, for it will he evident that to engrave or otherwise
produce such additional matter upon the roller would render it fit for use only in
printing such goods as are to bear that particular combination of marks. According
to my Invention I construct the copper or other printing roller in such a manner
that I can alter or remove parts thereof, which parts are engraved with or otherwise
carry the numbers, names or designs which accompany the main trade mark and
which I may desire from time to time to alter or dispense with. With this object
the roller is composed of a central core or mandril upon which I fix or slip shells,
rings or thimbles of copper or other suitable metal or material engraved with or
otherwise having or carrying a surface capable of printing the trade mark and other
interchangable combination marks, numbers, designs and the like. Compressing
nuts at the ends of the mandril or other means are provided to bind the whole
firmly together so that a homogeneous roller is produced presenting the required
combination of marks upon its surface. To change the combination it is only
necessary to remove the shell or shells bearing the particulars which it is required
to alter, and to replace it or them by another or by others engraved with or
carrying different matter or designs and thus a change in the combination is
effected with but little trouble or cost. The shells or rings may either be split
and applied in halves or portions to the core or mandril or they may be slipped
on from the ends of the mandril.

page_text: To render my Invention perfectly clear I will now proceed to describe the same
more particularly, reference being had to the annexed sheet of drawings.
Fig. 1 of the said drawings is partly an outside and partly a sectional view of
a printing roller constructed in accordance with my invention. It consists of a
central core or mandril a which may be of iron or steel carefully turned and cut
with a screw thread from end to end as shown. The reduced extensions b of the
mandril carry the driving wheels and revolve in the supporting bearings of the
machine. The mandril a carries a number of shells or rings c. c¹ c² c³ c c c made
of copper or other suitable metal or material and engraved or etched with sunk
lines or having the design in relief the said rings having been previously accurately
bored to fit the mandril a and turned on their peripheries so as to be all exactly
of the same diameter. The sides of the rings are also carefully turned. so as to
make a good joint with each other. To hold the rings in their proper position
and to keep them tightly in contact with each other I provide jamb nuts d d¹
which screw upon each end of the mandril. When working my improved roller
in the printing of trade marks upon piece goods for example, supposing that the
central ring was engraved with the main trade mark or design, that the ring c
carried numerals representing the number of yards and that was engraved with
some mark bearing a local or other significance, it will be evident that to change
the numerals on c or the subsidiary mark on c¹ without altering the main design
on all that is necessary is to remove the jamb nuts d. d' slip off the blank c
and the rings c¹ and c³ and replace the latter by rings bearing the required number
and sign after which the blank is re-applied and the jamb uuts replaced and screwed
up to their former position. To prevent the rings from turning on the mandril I
employ slip feathers which slide in a key way or groove e cut in the mandril a
or there might he two or more such keyways or grooves. The slip feathers which
I employ are each intended to engage with the rings and are preferably shaped as
shown in Fig. 2 which is a side view and plan of the feather. The feather f.
is slightly sloped towards each side from the centre one half of the feather
entering one ring and the other half the next abutting ring. These slip feathers
and grooves might however be dispensed with. In building up the improved roller,
blank rings are inserted where no design is required. The colour trough for
supplying colour to the built up roller may be divided into compartments opposite.
to the respective rings and filled with different colours so as to print the different.
parts of the combination with different colours if such should be desired. It will :
be evident that as the jamb nuts can be moved all over the mandril, one two or.
any number of the rings could be held between the nuts at any point in the length
of the mandril. But when it is convenient to use say only one ring or shell at a .
time I find it preferable to secure the said ring to the mandril by means other than .
the jamb nuts that is to say by slip keys which can be secured at any point in the
length of the mandril. For example referring to Fig. 3 g represents the single
ring which it might be desired to use in conjunction with the mandril a. The
keyway e in the mandril is slightly larger than that in the ring as shown at
Fig. 4. The key h is represented in perspective and to an enlarged scale at Fig. 5.
It consists of a lower vee shaped part h which slides in a correspondingly shaped
key-way e in the mandril a this key way being clearly shown in Fig. 4. Upon the
lower part is formed a wedge shaped part ¹ which enters and fits the keyways in
the ends of the ring 9. The lower part carries a screw h³ the foot of which is
just flush with or slightly above the level of the bottom of the part h. The
required position of the ring g having been fixed upon, the keys h are slid along
from each end of the mandril until the parts h' have both entered the keyways in
the ends of the ring g. I then turn the screws h² by means of a screwdriver thus
jambing the keys in the groove e and preventing any possibility of displacement
of the ring 9. To remove the ring it is only necessary to loosen the screws in the
keys h slide them out of the groove and then to slip off the ring.
Instead of placing the rings or shells upon the mandril in the form of complete
rings as hereinbefore described I might place them upon the mandril in sections

page_text: as in Fig. 6 which is a sectional view of the mandril as with a ring composed of
three sections. To secure these: sections together 1 form their edges inclined
outwardly as shown in Fig. 7, the neighbouring rings j being formed with similar
inwardly inclined edges which overlap and hold the sections i¹. Jamb nuts.
cottars or other suitable means are employed at the end or ends of the mandril to
hold the rings and sections firmly together. The rings might be applied in any
number of sections greater or less than three. Instead of having inclined edges
the rings and sections might be half checked or otherwise formed so as to engage
with each other.
Although in the foregoing description I have referred to my invention as being
more particularly applicable to rollers used in apparatus for printing trade marks.
upon folded piece goods it will be understood that I do not limit myself to this as
such rollers may be used to print in one or more colours upon other materials
such as calico and paper. My improved roller might be applied to existing
machines for printing upon such materials. It will also be understood that the
herein before referred to interchangeable printing rings or shells may be made of
copper or of any other metal or material capable of being used for printing
purposes. The designs may be engraved or etched in sunk lines on the said rings
or shells or the designs may be in relief or may be produced in any other manner.
When the shells or rings are split they may be applied in two, three or more parts
and in such a case I might arrange that only one of the said parts would carry
the design the other part or parts being blanks or filling up pieces of the same
or of a different or less valuable metal or material than the portion carrying the
design. The improved roller might revolve partly in the colour trough, or colour
might be transferred by suitable means to the roller from the colour receptacle or
receptacles.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :
(1) In rollers for printing upon textile fabrics and other materials and for
printing trade marks and other marks and devices upon folded piece goods, forming
the said rollers from a series of shells or rings engraved with or carrying designs
or certain of them engraved and certain of them blank, all of the said rings or
shells being strung upon a central mandril and held in position by suitable means
such as jamb nuts substantially as described and shown."
(2) In printing rollers of the aforesaid description the employment of a single
engraved ring or shell mounted upon a mandril and held in position by sliding.
keys substantially as described and illustrated.
(3) In printing rollers of the indicated description the application of the aforesaid.
engraved or other rings or shells to the central mandril in the form of sections.
having inclined or checked edges intended to engage with similarly inclined or
checked edges on the neighbouring sections or rings for the purpose of holding
them in place and so forming a homogeneous roller substantially as described and
shown..
