I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for Foreign
Patent Solicitors, 6 Lord Street, Liverpool and 6, Bank Street, Manchester, both
in the County of Lancaster and 323 High Holborn in the County of Middlesex
Civil Engineer, do hereby declare the nature of this invention to be as follows:-
This invention consists in the insertion of a metallic tube or lining in the guide
opening of the bushes of cop tubes and spools of paper or wood, such, for instance,
as in the "Booth-Sawyer" spools in ring spinning and ring twisting cop tubes or
spools and the like, with the object of enabling the paper spools and cop tubes to
be made mathematically exactly round, and of giving both paper and wood spools a
firmer and more level seat on the spindle and further to considerably reduce the
wearing away at the points of support. A rabbeth spool is fitted with one metal tube,
whilst a "Booth-Sawyer" spool, which only differs from the rabbeth spool in having
no spindle casing, on the other hand instead of only one metal tube, has two such
tubes which fit to the spindle. The metal tubes are also arranged on cop tubes in
a similar manner.
The use of metallic tubes is of particularly great advantage in making paper
cases and paper spools, as in the making of such tubes or spools the metallic tubes
press perfectly evenly on the winding spindle by which means the cases and spools
are obtained perfectly round which hitherto without the use of metal tubes could
only be partially obtained, as the paper material is too elastic for this object. If a
firm centre be provided as is the case where metallic tubes are used no expansion
of the inner paper casing when the spool or tube is completed can take place.
A further advantage consists in the circumstance that the completed spools or
holders rest with their metal tubes more evenly on the spindles than when they are
not provided with such tubes, and the wear is much less. This applies not only to
paper spools but also to wooden ones, the use of metal tubes being in this latter
case very advantageous as it enables them to be used for a much longer time. The
extremely small extra cost of making spools and cases with metal tube linings is
inappreciable.

[Price 8d.]

page_text: the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
This invention consists in the insertion of a metallic tube or lining in the guide
opening of the bushes of cop tubes and spools of paper or wood, such, for instance,
as in the "
Booth-Sawyer" spools in ring spinning and ring twisting cop tubes or
spools and the like, with the object of enabling the paper spools and cop tubes to
be made mathematically exactly round, and of giving both paper and wood spools
a firmer and more level seat on the spindle and further to considerably reduce
wearing away at the points of support.

seat on one spinate and futu
wearing away at the points of support.
In the accompanying drawings
Figure 1 is an elevation,
Figure 3 a vertical section, and
Figures 2 and 4 cross sections of a rabbeth spool A with a metallic tube or
lining a, and
Figure 5, is a vertical section,
Figure 7 an elevation, and
66
Figures 6 and 8 cross sections of Booth-Sawyer" spool A' which only differs
from the rabbeth spool in having no spindle casing C, whilst on the other hand,
instead of only one metal tube a, it has two such tubes a and a¹ which fit to the
spindle B. The metal tubes are also arranged on cop tubes in a similar manner but
this is not shown in the drawings.
The use of metallic tubes is of particularly great advantage in making paper
cases and paper spools, as in the making of such tubes or spools the metallic tubes
press perfectly evenly on the winding spindle, by which means the cases and spools
are obtained perfectly round which hitherto without the use of metal tubes could
only be partially obtained, as the paper material is too elastic for this object.
If a firm centre be provided as is the case where metallic tubes are used, no
expansion of the inner paper casing when the spool or tube is completed can
take place.
A further advantage consists in the circumstance that the completed spools or
holders rest with their metal tubes more evenly on the spindles than when they are
not provided with such tubes, and the wear is much less. This applies not only to
paper spools but also to wooden ones, the use of metal tubes being in this latter
case very advantageous as it enables them to be used for a much longer time. The
extremely small extra cost of making spools and cases with metal tube linings is
inappreciable.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, 1 declare that what I claim is :-
.66
In cop tubes and spools of any kind such for instance, as rabbeth spools,
Booth-Sawyer" spools, ring spinning and ring twisting cop tubes and spools and
the like, made of paper or wood, a metal tube or lining, or where there is no spindle
casing two or more such metal tubes or linings placed in the guide opening or
openings of the bush or bushes so as to bear evenly on the spindles when placed
thereon, substantially as and for the purpose described and illustrated.
