of wood they are liable to lose their shape when exposed to heat or damp and cast
iron is expensive and inconveniently heavy for the said articles.
According to this Invention cylinders drums or rollers that are light, cheap and
not liable to lose their shape are manufactured by the employment of compressed
or hardened paper or card board as hereinafter described. This material may be
rendered impermeable to moisture if desired by incorporating with it some
substance or substances such as paraffin, napthaline, resins or the like with the
pulp or paper stuff or material either before or after it has been worked into shape.
In carrying this Invention into effect materials such as are employed in making
paper, card, papier maché or the like are worked or moulded into the form of
segments or sections of cylinders and these segments or sections are used to build
up cylinders drums or rollers to be used in machinery for treating fibrous materials.
The sections or segments are connected together by means of a tongue and
groove dovetail stepped or other joint and metallic cross bars, arms or supports
preferably attached to the shaft or axis are imbedded in or attached to the
cylinders, drums or rollers in order to impart to them the requisite stiffness and
rigidity. If preferred the said cylinders drums or rollers may be moulded in one
niece

page_text: The cylinders drums or rollers manufactured according to this Invention have a
surface that, although extremely hard admits of being worked upon without
difficulty and the said cylinders drums or rollers being light cheap and capable of
permanently retaining their original shape are therefore fitted to be substituted
with great advantage for the wooden or cast iron cylinders drums or rollers heretofore
employed and will effect a considerable economy in the cost of carding and other
like machinery employed in the preparation of fibrous materials.

page_text: I, JOHN HENRY JOHNSON of 47 Lincolns Inn Fields in the County of Middlesex
Gentleman do hereby declare the nature of said Invention for "IMPROVEMENTS IN
THE MANUFACTURE OF CYLINDERS DRUMS OR ROLLERS FOR MACHINERY FOR
PREPARING OR TREATING FIBROUS MATERIALS" and in what manner the same is
to be performed to be particularly described and ascertained in and by the following
statement:
The cylinders drums or rollers which form part of machinery employed in the
treatment or preparation of fibrous materials such for example as spinning and
carding Engines have heretofore been commonly manufactured of wood or cast
iron. When made of wood they are liable to lose their shape when exposed to
heat or damp and cast iron although free from this objection is expensive and
inconveniently heavy for the purpose.
According to this Invention cylinders drums or rollers that are light cheap and
not liable to lose their shape are manufactured by the employment of compressed
or hardened paper card board or papier-maché materials or the like as hereinafter
described-This material may be rendered impervious to moisture if desired by
incorporating some substance or substances such as paraffin napthaline resins or the
like with the pulp or paper stuff or material before it has been worked or moulded
into shape, or impregnating the articles therewith after they have been formed.
In carrying this Invention into effect materials such as are employed in making
paper card board papier-maché or the like are worked or moulded (under any
suitable degree of pressure if desired) into the form of segments or sections of
cylinders and these segments or sections are used to build up cylinders drums or
rollers to be used in machinery for treating fibrous materials-These segments or
sections are connected together by means of a tongue and groove dovetailed stepped
or other form of joint fastening or connection and metallic cross bars, arms or
supports preferably attached to the shaft or axis (upon which the cylinders drums
or rollers are mounted) are embedded in or attached to the cylinders drums or
rollers in order to impart to them the requisite stiffness and rigidity-If preferred
the said cylinders drums or rollers may be moulded or formed in one piece and
when the dimensions are small this method will generally be found most
convenient.
The cylinders drums or rollers manufactured according to this Invention have a
surface that although extremely hard admits of being worked upon without
difficulty and the said cylinders drums or rollers being light cheap and capable of
permanently retaining their original shape are therefore fitted to be substituted
with great advantage for the wooden or cast iron cylinders drums or rollers here-
tofore employed and will effect a considerable economy in the cost of carding and
other like machinery employed in the preparation of fibrous materials.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what
I claim is.
1st In the manufacture of cylinders drums or rollers for use in machinery for
preparing or treating fibrous materials the employment of compressed or hardened
paper card board or papier maché materials or the like substantially as herein-
before described.

page_text: 2nd The manufacture of cylinders drums or rollers for use in machinery for
preparing or treating fibrous materials the employment of compressed or hardened
paper cardboard or papier maché materials or the like incorporated or impregnated
with a waterproofing substance substantially as herein before described.
3rd In the manufacture of cylinders drums or rollers for use in machinery for
preparing or treating fibrous materials the employment of paper card board or
papier-maché materials or the like with or without the addition of waterproofing
substance the said materials being first worked or moulded into the form of
segments or sections and then built up into cylinders drums or rollers and secured
together substantially as hereinbefore described.
