PROVISIONAL SPECIFICATION.
Improvements in Connection with the Spindles and Weight Hooks
of Spinning Frames.
WALTER CHATWOOD BURTON of 13 Harriett Street, Rochdale in the County of
Lancaster Engineers Draughtsman do hereby declare the nature of this invention to
be as follows:-
My invention relates to improvements in the Spindles and Weight Hooks in
connection with such yarn or other material Spinning Frames, as the Mule, Throstle,
Ring, Slubbing, Intermediate and Roving Frames.
My mechanism for the Spindle of Ring or Throstle Frames consists essentially of
an ordinary Spindle, with its lower or smaller end, turned either flat or curved, but
not coned, for in my said invention I require no brass or other metal coned bearing
footstep. The body or Bolster casing for the spindle may be of the Rabbeth, or other
Type, but its extremity just below the part which is screwed for fastening to the rail
must be countersunk. Upon this extremity a cup is screwed. This cup is provided
with an oil space or recess, which can be supplied with lubricant, without disengaging
the cup, by simply drilling a hole or providing a slot, from the upper to the lower surface
of the cup.
A screwed plug in the bottom may be used to facilitate cleansing out
the cup.
Immediately above this space in the cup, there is a circular or annular projection,
upon which rests, a small steel or other metal cone washer-This cone is inverted or
set in opposition to the counter sunk or similar shaped part, of the casing.
Between these two surfaces, a series of small spherical balls can play or revolve.
The balls surround the lower or smaller extremity of the tapered spindle, and form

page_text: the adjustable bearing for the spindle bottom. The adjustment may be set to a great
nicety, by simply turning the cap, and can be locked in any position, by the action of
a small pin or spring catching into a milled head; upon the cap.
In some cases I may use the ordinary spindle but greatly lessen the friction by
allowing the spindle pivot, to rest upon a spherical ball.
A slight modification of the ball casing will be sometimes requisite when used for
Mules, Slubbing, Roving or Intermediate Spindles.
My weight hooks consists essentially of an hook which is provided, at its upper
extremity with a disc or half circular ring, into which is fitted a series of balls. Theso
balls work or bear upon the roller or weighting surface, and are provided with an adjust-
ment similar to that hereinbefore described for the spindle, and thereby greatly reduce
the amount of friction and consequently the amount of power required for driving
purposes.

page_text: WALTER CHATWOOD BURTON of 53 Spotland Road Rochdale in the County of
Lancaster Engineers Draughtsman 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 said invention relates to improvements in the spindles and Weight Hooks in
connection with such, (or similar) spinning frames as the Mule, Ring, Throstle,
Doubler, Slubber, Intermediate, and Roving Frames, for Spinning yarns and other
materials.
My mechanism for the Ring frame Spindle consists essentially of either an ordinary
or taper spindle with its lower extremity flat or curved (but not coned as in the
ordinarily used spindle) for I dispense entirely with the brass coned fixed footstep
bearing. The bolster or body casing for the spindle may be of the ordinary or other
types, but its extremity, below the part which is provided with a screwed thread for
securing it to the rail, must be curved. Upon or in this extremity a cup or nut is
screwed. A steel coned or curved bearing is driven or otherwise fixed in the bottom
of the cup or upon the nut. The cone being inverted when viewed in relation to the
bearings in the casing and spindle bottom respectively. Between these two surfaces
a series of spherical balls can play.
The balls surround the lower extremity of the tapered spindle, and form its adjustable
bearing which can be lubricated without displacing the Spindle. The adjustment is
attained by turning the cup, which instantaneously actuates the balls, and owing to
the inclined planes of their bearing surfaces, causes them to approach or recede from
the Spindle according to the direction in which it is turned. A nut or its equivalent
is sufficient, to lock the cup in any definite position.
In preference to the above I may use only one ball and allow of either the ordinary
or an inverted taper spindle working and resting upon its prepared countersunk or
other surface. By these means I greatly diminish the frictional resistance; and by a
modification of the before mentioned device attain an adjustable spindle which can be
lubricated easily without displacement.
Slight modifications of this mechanism can be made and may be necessary, especially
when adapted to the Slubbing, Roving, Intermediates or Mules.
My Weight hook consists essentially of a hook provided at its upper extremity with
a disc or half circular casing into which is fitted a series of balls. These balls work or
bear upon the roller or weighting surface, and may be provided with adjustment;
similar to that of the Spindles herein before described-but I may prefer to only use
two balls in the casing and these in most cases without any adjusting nuts-in order
that the hooks may be raised from position more easily. And in order that my said

page_text: invention may be particularly described and ascertained, reference is hereby made to
the accompanying drawings, in which similar letters of reference indicate corresponding
parts.
Fig. 1 is a section of Spindle with one bearing ball.
Fig. 2 is a section of Spindle with a series of balls.
Fig. 3 is an elevation of the Weight Hook.
In figure 1, (a) is the inverted taper spindle which revolves within the split taper
bush.
(c) Figure 2, shews the spindle in its normal position.
In figures 1, & 2, (e) is the spherical ball or balls.
(f) is the cone or bearing resting upon cushion of rubber, felt, or other material.
(k) is the adjusting nut used for raising or lowering the bearings and simultaneously
causing the Spindle to accommodate itself in the top coned bearing so as to be free
from vibration even when revolving at the highest speeds.
The adjustment is locked in any suitable position by the nut (h).
The oil or lubricant is filled in at the opening (d). Hence the displacement of the
spindle is unnecessary. The spent oil or dregs may be emptied at the bottom by
unscrewing the nut (k) or equivalent mechanism.
In Figure 3, (m) is the roller or surface required to be weighted.
(n) is the hook prepared at its upper extremity to receive the two or more balls (0, 0). :
The piece (p) is used to keep the balls in position, and the form of the recess prevents
them from dropping out when the hook is taken off the roller.
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,
1st. The method of diminishing the friction and taking up the wear upon all
spindles, by fitting the same to work in contact with one or more balls substantially as
herein before described and illustrated on the drawings.
2nd. In all spindles the application of the inverted taper spindle with the ball (e)
for the purposes substantially as described and illustrated on the drawings.
3rd. The device or arrangement of inclined bearing planes in combination with the
adjusting nuts for the purpose substantially as described and illustrated.
4th. Arrangement of tube or recess for lubricating at (d) as and for the purposes.
substantially as described and illustrated.
5th. The general construction, combination and arrangement of balls, nuts, bearings,
and spindle applied to the. casings of spindles; together constituting my improve-
ments in spindles, substantially as and for the purposes herein before described and
illustrated.
6th. The method of diminishing the friction & consequent wear and tear of the
hooks by filling the same with balls in contact with the roller, substantially as herein
before described and illustrated.
7th. The general construction and arrangement of the hook whereby the balls
retain their position when the hook is displaced, as & for the purpose substantially as
described and illustrated in the sheet of drawings.
