SPINDLES EMPLOYED IN ROVING, SPINNING, AND TWISTING MACHINERY
follows:-
"
The object of my Invention is to reduce the friction on such studs or spindles
which now takes place as the wharle and tube rotate thereon.
As is well understood in the above class of machinery the tube and wharle are.
in contact with the studs throughout their whole length and as the said tubes
revolve at a very high rate there is considerable friction on the studs requiring
great power to drive the wharles and tubes.
My improvements consist in cutting a quick and broad spiral groove in the said
studs or spindles so that the surface contact with tubes is much reduced conse-
quently the excessive friction is removed and the power to drive the tubes lessened.
In addition to the spiral groove reducing the friction on the tubes it provides a
good method of lubricating them.
Instead of cutting a screw groove in the stud, grooves or recesses other than
spiral may be formed therein, or small metal rings may be placed upon the studs
at suitable distances apart, so as to lessen surface contact, or the said studs may bo
fluted or made angular in cross section.

I, EDWIN JAMES OATES of Ryburne Mill, Halifax, Yorkshire, Worsted Spinner,
do hereby declare the nature of my invention for "IMPROVEMENTS IN STUDS OR
" and in
SPINDLES EMPLOYED IN ROVING, SPINNING, AND TWISTING MACHINERY
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:—
The object of my invention is to reduce the friction on such studs or spindles
which now takes place as the wharle and tube rotate thereon.
As is well understood in the above class of machinery the tube and wharle are
in contact with the studs throughout their whole length, and as the said tubes or
wharles revolve at a very high rate, there is considerable friction on the studs
requiring great power to drive the wharles and tubes.
Such being the nature and object of my invention I will now proceed to describe
the same more fully and for that purpose have illustrated my improvements in the
accompanying sheet of drawings where A in Fig. 1 is the spinning cap, B the
wharle, and C the bobbin, all arranged and conducted in the ordinary manner,
D is the stud upon which the wharle and tube rotate, such stud having hitherto
been made with a plain surface of the same diameter as the size of hole formed
in the wharle and tube, consequently there were frictional contact throughout the
whole length of both wharle and tube.
To avoid this friction is the object of my invention, which I accomplish by
forming screw threads or grooves in the studs D, as shewn in Figs 1, 2, and 3, the
width and depth of groove varying according to taste and judgement of the spinner.
Instead of cutting screw threads or grooves at right angles to the axis of the stud
as previously shewn, I may form flutings or longitudinal grooves in the said studs
as shewn in Fig. 4, or I may make the said studs angular in cross section as shewn
in Fig 5 and 6, in all of which methods I obtain less frictional contact, whereby
less power is required to drive the machine as will be well understood.
In addition to the spiral grooves reducing friction, the grooves provide a good
method of lubricating the parts.
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 formation of studs and spindles substantially as herein shewn and described
for reducing frictional contact with revolving wharles, tubes, or bobbins, and as a
means of lubricating such studs and spindles,
