IMPROVEMENTS IN METAL ROLLERS FOR CALICO PRINTING, WALL PAPER PRINTING, EMBOSSING, CALENDERING AND THE LIKE
Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I, WILLIAM ALEXANDER CARLYLE of Constitution Hill, Birmingham, in the
County of Warwick, Electrician, do hereby declare the nature of my invention
for "IMPROVEMENTS IN METAL ROLLERS FOR CALICO PRINTING, WALL PAPER
PRINTING, EMBOSSING, CALENDERING AND THE LIKE," to be as follows:-
My Invention relates to Improvements in metal rollers for calico printing, Wall
paper printing, Embossing, Calendering and the like; and has for its object so to
construct such rollers that they will remain unchanged in wear for a longer time
than heretofore.
Such rollers as ordinarily made consist essentially either of a solid or hollow
copper cylinder sometimes having a nickel plated surface; or a cast iron or other
metal cylinder covered on the outside with copper which is sometimes nickel plated.
The surface of such rollers is soon injured by wear, by oxidizing, and by the
action of the chemicals in the dyes; and the colour of some of the dyes is thereby
changed and spoiled.
.
According to my Invention instead of using copper in constructing such rollers
I use either aluminium, aluminium bronze, or aluminium and bismuth bronze, or
alloys of aluminium with nickel, tin or copper, or with other metals with which
aluminium can be alloyed.
Such rollers made according to my Invention last much longer than heretofore
owing to the hardness and acid-resisting and non-oxidizing properties of the said
aluminium, aluminium bronze, or aluminium and bismuth bronze, or alloys of
aluminium. I use the said aluminium, aluminium bronze, or aluminium and bismuth
bronze, or alloys of aluminium as a solid or hollow cylinder in the manner in which
copper is now used; or by electrolytic means, I deposit the said aluminium,
aluminium bronze, or aluminium and bismuth bronze, or alloys of aluminium on
to a cast iron or other metal cylinder; or I form a tube of the said aluminium,
aluminium bronze, or aluminium and bismuth bronze, or alloys of aluminium and
draw it on to the said cast iron or other metal cylinder; or I cast a cylinder of
aluminium, aluminium bronze, or aluminium and bismuth bronze, or alloys of
aluminium around the said cast iron or other metal cylinder.

performed, to be particularly described and ascertained in and by the following
statement:
My Invention relates to Improvements in metal rollers for calico printing, wall
paper printing, embossing, calendering and the like; and has for its object so to
construct such rollers that they will remain unchanged in wear for a longer. time
than heretofore.
Such rollers as ordinarily made consist essentially either of a solid or hollow
copper cylinder sometimes having a nickel plated surface; or a cast iron or other
metal cylinder covered on the outside with copper which is sometimes nickel plated.
The surface of such rollers is soon injured by wear, by oxidizing and by the action
of the chemicals in the dyes; and the colour of some of the dyes is thereby
changed and spoiled.
According to my Invention instead of using copper in constructing such rollers
I use either aluminium, aluminium bronze or aluminium and bismuth bronze, or
alloys of aluminium with nickel, tin or copper, or with other metals with which
aluminium can be alloyed.
Such rollers made according to my Invention last much longer than heretofore
owing to the hardness and acid-resisting an non-oxidizing properties of the said
aluminium, aluminium bronze, or aluminium and bismuth bronze, or alloys of
aluminium. I use the said aluminium, aluminium bronze, aluminium and bismuth
bronze or alloys of aluminium as a solid or hollow cylinder in the manner in which
copper is now used, that is to say, by casting or forging or in any other well known
manner; or by electrolytic means I deposit the said aluminium, aluminium bronze,
aluminium and bismuth bronze or alloys of aluminium on to a cast iron or other
metal cylinder and for this purpose I use any of the well known aqueous solutions
of aluminium, aluminium bronze, aluminium and bismuth bronze or alloys of
aluminium and the ordinary well known apparatus for the deposition of the said
metals; or I form a tube of the said aluminium, aluminium bronze, aluminium and
bismuth bronze, or alloys of aluminiuin by casting and I bore it and draw it on to
a cast iron or other metal cylinder by any well known apparatus for such purposes;
or in the ordinary well known manner, as for instance in a sand mould or a chill,
I cast a cylinder of aluminium, aluminium bronze, or aluminium and bismuth
bronze, or alloys of aluminium around a cast iron or other metal cylinder.
Such metal rollers made as above described according to my Invention can be
turned and finished or engraved similarly to the copper rollers now used.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:
The Improvements in metal rollers for calico printing, wall paper printing,
embossing, calendering and the like as herein before described and specified, that is

page_text: to say, the application and use of aluminium, aluminium bronze aluminium and
bismuth bronze or alloys of aluminium to, for or with such rollers as and for the
purposes herein before described.
