PROVISIONAL SPECIFICATION..
Improvements, in Apparatus for Twisting and Doubling Yarns.
We, SAMUEL HERBERT BROOKS Machine Maker and JOHN SAMUEL BROOKS
Sub Manager both of the Union Iron Works, West Gorton, Manchester in the County
of Lancaster do hereby declare the nature of the said invention to be as follows:-
This invention relates to the measuring or trap roller in what are known as trap
twisting or doubling frames and is designed to increase the efficiency and the length
of wear of the covering used for this roller.
The roller as at present constructed can only be placed on the spindle in one
position and this only allows the upper portion of leather or other covering to.
come in contact with the yarn. The object of the present invention is to so construct
the roller as to enable it to be reversed on the spindle in a convenient manner for
the purpose of bringing the lower or unworn portion of the leather or other
covering into use and so considerably increase the life of such cover.
In carrying out the invention we construct the roller with a bearing for the
spindle at each end and instead of the present projecting tube or boss to carry the
driving lugs the roller is constructed with an interior tube or. boss so as not to
project beyond the ends. This interior tube runs from end to end or nearly so and
the roller is provided internally with lugs or drivers to engage with the spindle.
Both ends being constructed alike the roller can be put on the spindle, either
end up or can be reversed when required.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Twisting and Doubling Yarns.
We, SAMUEL HERBERT BROOKS, Machine Maker, and JOHN SAMUEL BROOKS,
Sub Manager, both of the Union Iron Works, West Gorton, Manchester, in the
County of Lancaster, 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:-
This invention relates to the measuring or trap roller in what are known as trap
twisting or doubling frames and is designed to increase the efficiency and the length
of wear of the covering used for this roller.
The roller as at present constructed can only be placed on the spindle in one
position and this only allows the upper portion of leather or other covering to come
into contact with the yarn. The object of the present invention is to so construct
the roller as to enable it to be reversed on the spindle in a convenient manner for the
purpose of bringing the lower or unworn portion of the leather or other covering
into use and so considerably increase the life of such cover.
The improvements will be fully described with reference to the accompanying
drawings.

Fig. 3. Sectional elevation of same.
The roller A shown in Fig. 1 is constructed with a sleeve or socket B which
projects beyond the end of the roller and also extends for some distance into the
interior to receive the, spindle. This construction renders the roller capable of
being used in one position only and the portion of the leather covering between the
dotted lines a-a' receives most of the wear.
By our improvements we construct the roller A' with a hollow tubular socket
or sleeve C extending through the interior from end to end to receive or fit onto
or over the spindle. The sleeve C is cylindrical throughout or of similar shape at
both ends so that either end can be fitted upon the spindle D, and is made
without any part projecting beyond the edge of the roller A' which might entangle
or interfere with the smooth travel of the yarn.
In the interior of the rollers lugs or struts d are provided to engage with the
spindle or spindle socket to cause the roller to be carried round and rotate with
the spindle. As both ends of the roller are constructed alike it can be placed upon
the spindle either end up and can be reversed when required thus the whole extent
of the surface of the roller can be subjected to equal wear.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. A trap roller for twisting and doubling frames constructed with internal sleeve
extending from end to end to receive the spindle and lugs for engaging therewith
to rotate the roller substantially as and for the purpose described and shown.
2. The improved construction and arrangement of trap roller for twisting and
doubling frames so that either end can be placed upon the spindle substantially as
.described and shown.
