PROVISIONAL SPECIFICATION.
Improvements in Machinery for Spinning and Doubling Cotton
and other Fibres.
1, EDWARD MAKIN, Junior, of 40 New Brown Street, Manchester, in the
County of Lancaster, Manufacturer, do hereby declare the nature of this inven-
tion to be as follows :-
My invention relates to those machines for spinning and doubling in which the
yarn passes from the bottom roller or rollers under and then over the top of the
top drawing roller in its passage to the spindle; at the present time the yarn is
apt to run off the edge of the top roller when the machine is slowing down or
being stopped; when this happens the yarn has to be guided on to the top of the
roller by hand after the machine is re-started.
According to iny invention I alter the top roller so that the yarn when it has
come off the edge of the roller will automatically run on to the roller when the
machine is re-started thus saving labour and waste.
To effect this I cut a nick or groove (or nicks or grooves) on one or both edges
of each top roller the nick or groove is cut so that the yarn when off the roller is
caught by one of the nicks in the edge of the roller and thus carried up to its
working position on the top of the roller.

and other Fibres.
I, EDWARD MAKIN Junior, of 40 New Brown Street, Manchester, in the
County of Lancaster, Manufacturer, 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 :—
My invention relates to those machines for spinuing and doubling in which the
yarn passes from the bottom roller or rollers under and then over the top of the
top drawing roller in its passage to the spindle; at the present time the yarn is apt
to run off the edge of the top roller when the machine is slowing down or being
stopped; when this happens the yarn has to be guided on to the top of the roller
by hand after the machine is re-started.
According to my invention I alter the top roller so that the yarn when it has
come off the edge of the roller will automatically run on to the roller when the
machine is re-started thus saving labour and waste.
To effect this I cut a nick or groove (or nicks or grooves) on one or both edges of
each top roller the nick or groove is cut so that the yarn when off the roller is
caught by one of the nicks in the edge of the roller and thus carried up to its
working position on the top of the roller.

page_text: And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying sheet of drawings reference being had
to the figures and letters marked thereon.
Figure 1 is an elevation showing one end of a top roller and a section of the
bottom roller of a doubling frame and
Figures 2 and 3 are two full size views of the top roller with nicked edges
according to my invention.
In Fig. 1, a designates the top drawing roller, the bottom roller, and c the
yarns the course of which is indicated by the arrows.
The top roller a in this case is shown with two reversely cut nicks a¹ a² respec-
tively on each edge so that whichever way it is placed in its bearings, and whichever
side the yarn may happen to slip off one of these nicks will catch it and auto-
matically restore it to its working position on the top of the roller a..
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
In spinning, and doubling machines-
A top drawing roller having a nick or nicks in either edge or both edges
substantially as and for the purposes herein set forth.
