PROVISIONAL SPECIFICATION.
An Improvement in Printers' Inking and like Rollers.
I, EDWIN MORETON, of No. 12, St. Mary's Parsonage, Manchester, in the
County of Lancester, and of King Street Mill, Stockport, in the County of Chester,
Printers' Roller Composition Manufacturer, do hereby declare the nature of this
invention to be as follows:-
My said invention relates primarily to inking rollers composed of vulcanized or
other india rubber and a composition of gelatine and glycerine in certain proportions
according to the purpose for which the roller is intended to be used and which india
rubber and other composition encloses the ordinary wood or metal spindle or stock
but may be applied to rollers composed of other substances used for lithographic
and other purposes. The object intended to be achieved by my said invention is an
increased uniform elasticity combined with greater durability than is attained and
secured by the ordinary roller thereby effecting considerable economy.
The accompanying drawing will more easily set forth the nature of my said
invention.
Figure 1 represents a longitudinal section.
Figure 2 represents a cross or transverse section.
A indicates the outer coating of india rubber vulcanized or otherwise..
B indicates the composition of gelatine and glycerine or other suitable elastic
substance.
C indicates the spindle or stock.
I usually produce this improved printing roller by placing the india rubber or
other suitable clastic coating A in a mould the india rubber or other coating
touching the inner surface of the mould. I then place the spindle or stock C
directly through the centre of the mould and afterwards run the composition of
gelatine and glycerine or other suitable elastic substance B in a liquid state into
the space between the spindle or stock and the inner surface of the outer coating of
india rubber or other suitable elastic substance. I do not however confine myself
to this mode of production but at present I find it work most efficiently. The
relative proportions of india rubber or other suitable elastic coating and the com-
position of gelatine and glycerine or other suitable elastic substance are governed
by the purposes for which the roller is intended to be used and the temperature of
the climate where the roller is proposed to be worked.
As 300n as the composition has cooled or set the roller is ready for use and when
brought under pressure in working the india rubber coating A and the composition
of gelatine and glycerine B contracts and immediately expands again when the
pressure is withdrawn thus producing during rotation the increased uniform elasticity
on the outer surface of the roller.

An Improvement in Printers' Inking and like Rollers.
I, EDWIN MORETON, of No. 12, St. Mary's Parsonage, Manchester, in the
County of Lancaster, and of King Street Mill, Stockport, in the County of Chester,
Printers Roller Composition Manufacturer, 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 :-
My said invention relates primarily to inking rollers composed of vulcanized or

page_text: other india rubber with a finely textured linen or other suitable cloth lining and a
composition of gelatine and glycerine in certain proportions according to the purpose
for which the roller is intended to be used and which india rubber with lining and
other composition encloses the ordinary wood or metal spindle or stock but may be
applied to rollers composed of other substances used for lithographic and other
purposes.
The drawing left with the Provisional Specification will more easily indicate the
nature of my said invention wherein
Figure 1 represents a longitudinal section.
Figure 2 represents a cross or transverse section.
A indicates the outer coating of india rubber vulcanized or otherwise with the
fine linen or other cloth lining.
B indicates the composition of gelatine and glycerine or other suitable elastic
substance.
C indicates the spindle or stock.
The process adopted by me in the production of this improved printing roller is
as follows place the india rubber or other suitable elastic coating A with the
finely textured linen or other suitable cloth lining on the inner surface in a mould-
the india rubber or other coating touching the inner surface of the mould. I then
place the spindle or stock C directly through the centre of the mould and afterwards
run the composition of gelatine and glycerine or other suitable elastic substance B
in a liquid state into the space between the spindle or stock and the finely textured
india or other suitable cloth lining which is the inner surface of the outer coating of
Hinon rubber or other suitable elastic substance. As soon as the composition lias
cooled or set the roller is ready for use.
The relative proportions of india rubber or other suitable elastic coating with
linen or other lining and the composition of gelatine and glycerine or other suitable
elastic substance are governed by the purposes for which the roller is intended to
be used and the temperature of the climate where the roller is proposed to be
worked.
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
1. An increased uniform elasticity as when the roller is brought under pressure
in working the india rubber coating A and the composition of gelatine and
glycerine B contract and immediately expand again when the
pressure is withdrawn-
thus producing during rotation the increased uniform elasticity on the outer surface
of the roller.
2. Greater durability than is attained by the ordinary roller as the india
rubber coating is not of such a wearing out nature as the composition of the ordinary
roller.
3. Considerable economy as although at present my improved roller may cost
rather more than the ordinary roller yet my roller is far more durable.
Dated this 9th day of February 1891.
