PROVISIONAL SPECIFICATION.
The Producing of a Silk like Surface upon Webз of Cotton or Wool or
other Materials not being Silk.
GEORGE WILLIAM CHAMBERS KIRKHAM, Hadley Hall, New Barnet, Herts,
Buyer (Cotton), do hereby declare the nature of this invention to be as fol-
lows:-
I find that upon examining a web of silk that its surface consists of a number
of furrows or ridges & these furrows I find are brighter on the top & somewhat
wider at the bottom than the top & that these intemediatory spaces are
somewhat wider than the ridge itself. Also that a line runs accross these
ridges at an angle, which line consists of a ridge having the same intermediatory
space like the first.
The silk finshes now being produced are produced by means of rollers or
callanders that are serated or scored & whose action is to produce a bright
surface upon the whole of the web consequently when the webs are exposed
to the light at certain angles a metalic lustre is given to the web, which is a
most serious objection because in silk webs this metalic lustre does not occur,
this metalic lustre is owing to the whole surface of the web being serated &
bright.
My invention consists in making the grooves on the callander or roller at
various distances and sizes and also of producing a right surface on the top and
not on the bottom of the ridge, or a brighter surface on the top than on the
bottom of each ridge. This would be accomplished by bringing that portion of
my callander which is to produce the bright top of the ridge into contact
with the web when between the callanders with a greater pressure on the smooth
callander than the intermediatory portions would receive consequently this would
make these portions brighter whilst they in their turn would protect what was
required dull and for this purpose I should pass the web through the callanders
with its face presented to the plain callander and its back to the serated one.
The serated callander would be engraved or sunk in any direction and I
should also have it sunk or not to shew the diagonal line mentioned or produce
this with a second roller or callander.

The Producing of a Silk like Surface upon Webs of Cotton or Wool or
other Materials not being Silk.
GEORGE WILLIAM CHAMBERS KIRKHAM, Hadley Hall, New Barnet, Herts,
Buyer (Cotton), do hereby declare the nature of this invention and in what
Prine 8d 1

page_text: manner the same is to be performed, to be particularly described and ascertained
in and by the following statement:
-
I find that upon examining a web of silk, that its surface consists of a number
of furrows or ridges and these furrows 1 find are brighter ou the top and
somewhat wider at the bottom than the top and that these intermediatory
spaces are somewhat wider than the ridge itself. Also that a line runs across
these dges at an angle, which line consists of a ridge having the same inter-
mediatory space like the first.
The silk nuishes now being produced, are provided by means of rollers or
calenders that are serrated or scored and whose action is to produce a bright
suriace upon the whole of the web consequently when the webs are exposed
to the light at certain angles a metallic lustre is given to the web which
most serious objection because in silk webs this metallic lustre does not occur,
this metallic lustre is owing to the whole surface of the web being serrated and
bright.
a
My invention consists in making the grooves on the calender or roller at
various distances, and sizes:-see A, B, C, D, on sketch page 4, which are
each grooved in different and distinct directions at various intervals. Also see
calenders or rollers G, H, J K, on same page these are plain polished or bur-
nished calenders.
The process consists in passing a web of cotton or other material through
rollers either A and G. B, and HC, and J, or D, and K with its face surface
in contact with either of the calenders G, H, J, or K. The result is that the
grooved calender will force a certain portion of the face of the material into
contact with the plain calender this produces the silk finish referred to.
E is an enlarged plan and F is an enlarged section of a portion of one of
the grooved rollers.
And also of producing a bright surface on the top and not on the bottom of
the ridge or a brighter surface on the top than on the bottom of each ridge.
This would be accomplished by bringing that portion of my calender which is
to produce the bright top of the ridge into contact with the web when between
the calenders with a greater pressure on to the smooth calender G, H, J, K than
the intermediatory portions would receive, consequently this would make these
portions brighter whilst they in their turn would protect what was required
dull, and for this purpose I should pass the web through the calenders with its
face presented to the plain calender and its back to the serrated one.
The serrated calender would be engraned or sunk in any direction, and I
should also have it sunk or not to show the diagonal line mentioned or pro-
duce this with a second roller or calender.
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 as new is:-
First making the furrows on the calender or web of various distances or
sizes (E, and F).
Second-The producing of greater brightness on the top than the bottom 4
of the furrows and this I claim is effected by passing the web through the
calender with their back surface in contact with the serrated calender (A, B,
C, D).
Third-The producing of a silk-like surface upon webs of cotton or wool or
other materials not being silk.
