PROVISIONAL SPECIFICATION.
Improvements in or relating to Cap and similar Spinning
Machinery.
We, EDMUND GILYARD, of 74, Barkerend Road, Bradford, in the County of
York, Engineer, and CHARLES WARD, of 42, Hill Side Road, Bradford,
aforesaid, Watchmaker, do hereby declare the nature of this invention to be as
follows :-
of
This invention relates to improvements in ball bearings for supporting the tubes
cap and similar spinning machinery, and its object is to enable fewer balls to be
used in this class of bearing and also enable them to be more readily cleaned.
For this purpose we employ three or more balls placed in an annular groove
preferably formed in the top face of a "washer" surrounding the spindle. The
balls are separated by a perforated disc having a perforation for each ball an equal
distance apart and also a central perforation for the spindle. This disc may rest
on a raised lip on the washer formed around the hole for the spindle. The
revolving cap supporting the wharle and tube has preferably an annular groove
formed in its under side to rest upon said balls and it may have a conical seat at
the top to receive the usual projection on the bottom of the wharle. The cap may
be loosely connected to the washer by a concentric screw or pin or its equivalent
having a central hole for the spindle loosely passed through the cap and screwed,
wedged or otherwise fixed in the washer below. The said screw is provided with
a flange or head at the top to keep the cap down.
A flange may be formed round the washer outside projecting above the cap so
as to prevent the lubricant being thrown off by centrifugal force.

Improvements in or relating to Cap and similar Spinning
Machinery.
We, EDMUND GILYARD, of 74, Barkerend Road, Bradford, in the County of
York, Engineer, and CHARLES WARD, of 23, Hillside Terrace, Bradford,
aforesaid, Watcl:maker, late of 42, Hill Side Road, Bradford, 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 improvements in the ball bearings employed to support
the tubes of cap and similar spinning machinery, and its object is to enable fewer
balls to be used in this class of bearing and also enable them to be more readily
cleaned.
For this purpose we employ three or more balls placed in an annular groove
preferably formed in the top face of a "washer" surrounding the spindle. The
balls are separated by a perforated disc having a perforation for each ball an equal
distai.ce apart and also a central perforation for the spindle. This disc may rest

revolving cap supporting the wharle and tube has preferably an annular groove
formed in its under side to rest upon said balls and it may have a conical seat at
the top to receive the usual projection on the bottom of the wharle.
In the accompanying sheet of drawings forming a part of this Specification,
Figure 1, represents an elevation of a portion of a spindle with a tube thereon
and our improved bearing applied thereto.
Figure 2, represents a similar view with the tube and bearing case in section.
Figure 3, represents a plan view of Figure 1 without the tube and wharle.
Figure 4, represents a similar view without the said revolving cap.
Figure 5, represents a diametrical section of the said cap.
Figure 6, represents a diametrical section of the said perforated disc.
Figure 7, represents a plan view of the same.
Figures 8 and 9 respectively represent a diametrical section and a plan view of
the "washer or bearing case.
"
The case A resting upon the lifter plate B is made with a central hole A 2
for the spindle B2 to pass through and also a concentric annular groove A.3
to receive the balls C. A lip or rim A4 is formed round the hole A 2 to
support the disc D made with a perforation D2 for the spindle, and perfora-
tions D3 for the balls C. The revolving cap F has a concentric annular
groove F2 in its under side which rests upon the balls C. The cap F may
be loosely confined in the case A by means of the wire ring H sprung beneath
the projections A 5 formed in the interior of the casing. Or it may be secured
therein in any other convenient manner. A conical scat F 3 is formed on the top
of the cap to receive the projection J on the under side of the wharle J 2. The
object of this seat is to form a sort of friction clutch and ensure the cap F
revolving with the wharle J 2 and tube K. The flange or sides A 6 of the
washer projecting above F prevents the lubricant being thrown off by centrifugal
force.
The grooves A 3 and F 2 need not be made so deep as shown in the drawing
or they may be dispensed with.
It is obvious that more than three balls may be used if desired, but we find
three balls give very satisfactory results.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
we are aware ball bearings are old in principle and have previously been applied
in a similar position to support the wharles and tubes of spinning and twisting
machinery and we make no claim to the application of ball bearings for that
purpose, but what we claim is:
1. In tube spinning and twisting machinery, the combination with a ball bearing
for supporting the wharle and tube, of the perforated disc D, substantially as
berein shown and described.
2. In tube spinning and twisting machinery, a ball bearing for supporting the
wharle and tube, having a revolving cap F provided with a conical seat F 3,
substantially as herein shown and described.
