PROVISIONAL SPECIFICATION.
Improvements in Spindles Employed in Machines for Preparing and
Spinning Cotton and other Fibrous Materials.
I, BENJAMIN ALFRED DOBSON, of Kay Street Works, Bolton, in the County
of Lancaster, Machine Maker, do hereby declare the nature of this invention,
which has been communicated to me from abroad by Auguste Kirschner, Mill
Manager, of St. Etienne, France, to be as follows :-
This invention relates principally to the class of spindles employed in slubbing,
intermediate, roving and jack frames.
Waste and fly, as is well known, accumulate in the inside of the spindle collars
and by degrees become compressed into a solid hard mass which offers a certain
amount of resistance to the working of the spindles and to prevent this is the chief
object of the present invention.
In carrying out the invention I cut in or on the spindle a groove and this groove
is cut in such a manner as to leave on the spindle a sharp edge.
In operation the collar round which the bobbin revolves traverses up and down
the spindle and any accumulation of waste or fly inside the collar is cut away by
this sharp edge and allowed to drop out at the bottom of the collar.
I do not confine myself to the number of grooves formed upon the spindle or
to the shape of them and further the bearing of the collar may be rifled or grooved
for the same purpose and may also be used in conjunction with the groove or
grooves cut upon the spindle.
Dated this 27th day of December 1895.

1, BENJAMIN ALFRED DOBSON, of Kay Street Works, Bolton, in the County
of Lancaster, Machine Maker, do hereby declare the nature of this invention,
which has been communicated to me from abroad by Auguste Kirschner, Mill
Manager, of St. Etienne, France, 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 principally to the class of spindles employed in slubbing,
intermediate, roving and jack frames.
Waste and fly, as is well known, accumulate in the inside of the spindle collars
and by degrees become compressed into a solid hard mass which offers a certain
amount of resistance to the working of the spindles and to prevent this is the chief
object of the present invention.

page_text: In carrying out the invention I cut in or on the spindle a groove and this groove
is cut in such a manner as to leave on the spindle a sharp edge.
In the accompanying sheet of drawings-
Figure 1 is a sectional elevation of a spindle of the class specified to which the
improvements are shown applied and Fig. 2 is a detail view of the spindle on a
larger scale.
In Figure 1, a designates the spindle, b the flyer, e the slubbing or roving,
d the bobbin, e the long collar, f the bevel pinion or skew gear, and g the bobbin
rail.
The groove a¹ cut for the purposes of the invention with a straight shoulder is
clearly shown in both Figs. 1 and 2, the shoulder forming a sharp cutting edge
which in operation, as the long collar e is traversed up and down the spindle, cuts
away any waste or fly accumulated inside the collar.
I do not confine myself to the number of grooves formed upon the spindle a or
to the shape of them, and further the bearing of the collar e may be rifled or
grooved at el for the same purpose, and may also be used in conjunction with the
groove a¹ (or grooves) cut upon the spindle. Again instead of rounding off the
shoulder where the diameter of the spindle is reduced I prefer to make it with a
straight shoulder to form a sharp edge a² as shown.
Having now particularly described and ascertained the nature of this said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Forming a sharp edge or edges on the spindle a for the purpose of cutting out
accumulated waste or fly substantially as herein set forth.
2. The combination with the collar e, of the spindle a having a sharp edge or
edges formed thereon substantially as and for the purposes herein set forth.
Dated this 21st day of August 1896.
