Improvements in the Method of Compressing Brass Covered Rollers
for Wet Spinning Frames.
JAMES BARBOUR Falls Foundry Belfast County Antrim Ireland Machinist do
hereby declare the nature of this invention to be as follows:-
These improvements relate to the brass covered fluted rollers for wet spinning
frames which require to be free from pores or cracks in their fluted surfaces which
when working come in contact with the material to be drawn.
These improvements relate to the method of compressing brass covered rollers for
wet spinning frames and are an extension of the idea for which letters patent
No. 5639-24 April 1886 were granted to the present applicant.
These improvements consist in applying the rolling pressure requisite to compress
the surface of the bosses of the rollers across the face of the bosses and parallel to
their axis or in the direction of the roller's length and when the roller is not rotating.
The means employed in carrying out these improvements consist of compressing
runners free to revolve in contact with the bosses of the rollers to be compressed.
The rollers to be compressed are placed in suitable surface supports or V's on the
moving table of a fluting or planing machine and are carried backwards and forwards
underneath fixed runners free to revolve. The surface of the runners being made of a
shape to correspond with the surface required on the bosses being compressed.
The compressing runners are placed in the holders for the ordinary cutting tools
and they are brought into contact with the rollers to be compressed and the amount of
compression required is given by the same adjusting mechanism in use for the ordinary
cutting tools.
The entire surface of the bosses of the rollers is exposed to the compressing action
of the runners by turning the roller partially round on its axis between each passage
of the table until the full circumference has been submitted to the operation.

page_text: This compressing operation can be performed before or after the fluting process in
the latter case however a smoother flute can be obtained than is possible from the
ordinary fluting tool at present in use a result which is of the utmost importance
especially in frames for spinning fine yarns where it is necessary to obtain a surface
perfectly smooth and free from pores or cracks.
Improvements in the Method of Compressing Brass Covered Rollers
for Wet Spinning Frames.
JAMES BARBOUR of Falls Foundry Belfast County of Antrim Ireland Machinist
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:-
These improvements relate to the brass covered fluted rollers for wet spinning
frames which require to be free from pores or cracks in their fluted surfaces which
when working come in contact with the material to be drawn.
These improvements relate to the method of compressing brass covered rollers for

No. 5639 24 April 1886 were granted to the present applicant.
These improvements consist in applying the rolling pressure requisite to compress
the surface of the bosses of the rollers across the face of the bosses and parallel to
their axis or in the direction of the rollers length and when the roller is not rotating.
The means employed in carrying out these improvements will be understood from
the following description reference being had to the drawing annexed in which the
same letters and figures of reference apply to the same or like parts.
Fig. 1 is a side view of part of a brass covered roller on a fluting machine table
with the compressing runner in position.
Fig. 2 is a sectional end view of same.
Fig. 3 are enlarged sections of different forms of runners used.
The means employed in carrying out these improvements consist of compressing
runners (a) free to revolve in contact with the bosses (6) of the roller to be
compressed.
The rollers to be compressed are placed in suitable supports (c) on the moving
table (d) of a fluting or planing machine and are carried backwards and forwards

the rollers (6) being made of a shape to correspond with the surface required on the
bosses (b) of the roller which is to be compressed.
The compressing runners (a) are placed in the holders (e) for the ordinary cutting
tools and they are brought into contact with the bosses (b) of the rollers to be
compressed and the amount of compression required is given by the same adjusting

action of the runners (a) by turning the roller partially round on its axis between
each passage of the table (d) until the full circumference has been submitted to the
operation.
This compressing operation can be performed either before or after the fluting
process but it is better to compress the surface of the bosses (b) after the flutes have
been formed therein for by so doing a denser surface and a smoother flute can be.
obtained than is possible from the ordinary fluting tool at present in use a result
which is of the utmost importance especially in frames for spinning fine yarns where
it is necessary to obtain a surface perfectly sinooth and free from pores or cracks.
-
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 means described for compressing the surface of brass covered rollers for wet
spinning frames by rolling pressure applied across the face of the bosses and parallel
to their axes or in the direction of the rollers length and when the roller is not rotating.
