Year: 1878

page_text: LETTERS PATENT to Charles Greenwood and Arthur Benjamin Crossley, both
of Halifax, in the County of York, for the Invention of "IMPROVEMENTS IN
THE CONSTRUCTION OF ROLLERS FOR WASHING AND WRINGING MACHINES."

PROVISIONAL SPECIFICATION left by the said Charles Greenwood and
Arthur Benjamin Crossley at the Office of the Commissioners of Patents on
the 29th April 1878.
CHARLES GREENWOOD and ARTHUR BENJAMIN CROSSLEY, both of Halifax, in the
County of York. "IMPROVEMENTS IN THE CONSTRUCTION OF ROLLERS FOR
WASHING AND WRINGING MACHINES."
The object of this Invention is to make the rollers of such machines so as to
prevent them cracking or speedily wearing away, as is the case with the present
construction of wood rollers.
-
The improvements consist in fixing or placing a thick layer of paper or paper
pulp upon either an iron shaft or upon a wood roller. This shaft may have
projections thereon, so as to prevent the layer of paper from slipping.off.
Another method of making rollers for such machines consists in covering an iron
or other shaft or roller with felt, or in weaving a layer of cotton or other suitable
material upon a shaft or roller.
In any of the above methods of forming rollers for washing and wringing
machines, we may cover them with a layer of india-rubber, either in its pure or
manufactured state.

CHARLES GREENWOOD and ARTHUR BENJAMIN CROSSLEY, both of Halifax, in the
County of York. 'IMPROVEMENTS IN THE CONSTRUCTION OF ROLLERS FOR
WASHING AND WRINGING MACHINES."
The object of this Invention is to make the rollers of such machines so as to
prevent them from cracking or speedily wearing away, as is the case with the
present construction of wood rollers.
The improvements consist in fixing or placing a thick layer of paper, cotton, or
paper, or cotton pulp, upon either an iron shaft, wood roller, or tube. This shaft,
roller, or tube, may have projections thereon, so as to prevent the layer of paper or
cotton from slipping off.
Another method of making rollers for such machines consist in covering an iron
or other shaft or roller with felt, such felt consisting of either cotton, wool, or other
fibrous materials, either pure or mixed.
The method or manner of applying or fixing any of these materials to or upon a
shaft, roller, or tube, may be accomplished in various ways.
In using paper for the manufacture of these rollers, it may be applied either in
sheets or in a continuous sheet, lapped or rolled firmly around a solid body until
the requisite size is obtained.
If paper pulp is used it may be pressed upon a solid or hollow body by means
of a press and ram operated by hydraulic or other power.
When fibrous materials are used for the construction of rollers for this class of
machine, they may be applied by any of the well-known means of forming felt by
adding or rolling one film or layer of thin fibrous materials upon another until the
requisite thickness or diameter is obtained, when it may be taken and pressed into
a perfectly solid and firm roller; or fibre may be taken in any state, and by means
of hydraulic or other power compressed upon a shaft or roller into the proper size
and shape.
Another method of making or manufacturing rollers consists of weaving a layer of
cotton or other material upon a shaft or roller.
In any of the above methods of forming rollers for washing and wringing
machines, we may cover them with a layer of india-rubber, either in its pure or
manufactured state.
Having now described the nature and particulars of this our Invention, and ex-
plained how the same may be performed or carried into practical effect, we would
have it understood that we lay no claim to the machinery or mechanism herein
referred to,nor do we confine ourselves to any particular class of machinery employed
for rolling or pressing the materials herein mentioned, but what we do claim and
consider to be new is, the manufacture or construction of rollers composed of paper,
or fibres, or fibrous materials for use in domestic washing and wringing machines, sub-
stantially as herein described.
In witness whereof, we, the said Charles Greenwood and Arthur Benjamin
Crossley, have hereunto set our hands and seals, this Twenty-sixth day of
October, in th● year of our Lord One thousand eight hundred and seventy-
CHARLES GREENWOOD. (L.S.)
ARTHUR B. CROSSLEY, (L.S.)
