PROVISIONAL SPECIFICATION.
Improvements in Machinery for Roving, Reducing, Spinning,
and Twisting Fibrous Material.
I, CHARLES BRIGG, of Evergreen Cottage, Manchester Road, Bradford, in
the County of York, Washer Manufacturer, do hereby declare the nature of this
invention to be as follows
-
This invention relates to improvements in that class of machinery for roving,
reducing, spinning and twisting fibrous material in which the spindles pass through
a lifter plate and are not supported at the top, and its object is to provide an
improved form of stay or collar on the lifter plate to steady the spindles.
For this purpose I employ a stay or collar for each spindle bored to fit the
spindle and having its outer periphery, or a portion of its outer periphery, of
spherical form. This spherical portion fitted into a spherical or partly spherical
casing adapted to be secured to the lifter plate. This forms a ball and socket
Joint between the stay and the lifter plate which, whilst holding the stay perfectly
steady, allows it to adjust itself to the spindle.
The said casing may be divided diametrically and the two parts secured together
in any convenient manner An annular flange may be formed round each part by
which they may be secured together and to the lifter plate as well. The edge of
the upper flange may be turned up to form a recess or cup for a lubricating wad.
A pin is fixed in the stay loosely fitting a hole or notch in the casing to prevent
the stay evolving. The stay may pass through the lifter plate and the spherical
portion be partly let into it. One or more radial oil ducts, proferably inclined
downward towards the spindle, may be formed through the stay and casing for
the pm pose of conducting the lubricant from the felt wad in the cup to the spindle.
Or a portion of the stay may be cut away to bring the wad in contact with the
spindle to clean and lubricate it.
The stay aud casing may be covered by a cylindrical cap placed over it which
forms a beating for the drag washer and this cap may be either approximately
flush with the top of the stay or the latter may pass through it The cap may be
kept from 1otating by means of a pm or the like let into the litter plate engaging
a notch the side of the cap. On a projection on the bottom of the cap may
engage a hole in the lifter plate
Instead of the said casing being formed to the portion of a sphere it may be
angular and be formed to touch the spherical portion of the stay at different
points to support it.
Dated this 3rd day of October 1894.

and Twisting Fibrous Material.
I, CHARLES BRIGG, of Evergreen Cottage, Manchester Road, Bradford, in
the County of York, Washer 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 aud by the following statement :-
This invention relates to improvements in that class of machinery for loving,
reducing, spinning and twisting fibrous material in which the spindles pass through
a lifter plate and are not supported at the top, and its object is to provide an
improved form of stay or collar on the lifter plate to steady the spindles
For this purpose I employ a stay or collar for each spindle bored to fit the spindle
and having its outer periphery of spherical form. This spherical portion is fitted
into a spherical or partly spherical casing adapted to be secured to the lifter
plate. This forms a ball or socket joint between the stay and the lifter plate
which, whilst holding the stay perfectly steady, allows it to adjust itself to
the spindle.
The said casing may be divided diametrically and the two parts secured together
in any convenient manner. An annular flange may be formed round each part
by which they may be secured together and to the lifter plate as well. The edge
of the upper flange may be turned up to form a recess or cup for a lubricating wad.
A pin is fixed in the stay loosely fitting a hole or notch in the casing to prevent
the stay revolving. The stay may pass through the lifter plate and the spherical
portion be partly let into t One or more radial oil ducts preferably inclined
downwards towards the spindle. may be formed through the stay and casing for
the purpose of conducting the lubricant from the felt wad in the cup to the spindle
Or a portion of the stay may be cut away to bing the wad in contact with the
spindle to clean and lubricate it.
The stay and casing may be covered by a cylindrical cap placed over it which
forms a bearing for the diag washer and this cap may be e.thor approximately
flush with the top of the stay on the latter may pass through it
Reference is to be had to the accompanying sheet of drawings forming a part
of this Specification, in which similar letters of reference indicate corresponding
parts m each of the figures
Figure 1, represents a cross section of the lifter plate though my improved stay
with the flyer and a portion of the spindle in full.
Figure 2, represents a plan view of the stay and a portion of the lifter plate
Figure 3, represents a section of the same on the bioken line a, b Figure 2.
Figures 4, 5 and 6 represent similar views to 1, 2 and 3 illustrating a inodification.
Figures 7 and 8 represent similar views to Figures 1 and 2 illustrating a further
modification
Figure 9 represents a similar view to Figure 4 illustrating the application to
a cap spindle.
Figures 10 and 11 illustrate a form of wad cup and cap I may use when the former
18 not attached to the stay.
The lifter plate A the fly spindles B and flyers C, the cap spindle D and
the wharle E are of any ordinary construction.
The stays F are bored to fit the spindles and the stay shown in Figures 1,
2 and 3 is made with the central portions G of its periphery of spherical form.
The spherical portion 18 mounted in a spherical casing formed by the two plates J
and K riveted together by the rivets L passed through the flanges J and K
formed around them. The stay and casing are secured to the lifter plate by
the screws M, M ; and the periphery J of the flange J' is turned up so as to form

page_text: an annular cup Q around the stay adapted to receive a felt wad N to hold oil
or other lubricant. The stay is prevented from rotating by the pin O fixed in
the stay projecting into the hole P formed in the plate J and K but this hole
however is made sufficiently large to allow the stay to adjust itself parallel to
the spindle. An oil duct R is drilled through the casing and stay to allow oil
to pass from the wad to the spindle, and the stay is cut away at the top on one side
to allow the upper wad N' to come in contact with the spindle to clean it as
described in the Specification of my previous application No. 16,883 dated the
5th day of September 1894. The wads and cup Qare preferably covered by
a cylindrical cap S having a central opening for the spindle to pass through and
& notch formed in the side S to engage a projection K³ on K' and prevent it
rotating.
In
It is not essential for the casing to be of spherical form as it may be angulai
and be made to touch the spherical portion of the stay at different parts to support
it. Figure 12, represents a diametrical section of a stay and such a casing.
this figure the casing is made in the form of two truncated cones, and A respectively
formed in the plates J and K and placed base to base.
In Figures 4, 5 and 6 the upper part J of the casing is dispensed with and tho stay
is formed with a hemispherical collar G' fitting a hemispherical recess K' and is
secured in position by the nut G³ secured upon the projection F on its underside
bearing against the spring washer G introduced between it and the lifter plate.
In this case the hemispherical collar allows the stay to adjust itself parallel to
the spindle as the nut G is tightened up. The periphery of the flange K*
is turned up to form the cup Q for the wad.
The stay shown in Figures 7 and 8 is the same as that described in the Speci-
fication of my above cited application but it is provided with an annular wad cup
around t A cap of larger diameter is shown in Figure 7 to carry a larger
drag washer
ני
In Figures 10 and 11 a cup Q 18 represented which is made detached from
the stay.
A central hole QQ is made through the bottom of the cup for the spindle and
stay to pass through and it may be held stationary by the collar F' of the stay,
beaung on the bottom of the cup around the hole and clamping it against the
lifter plate, or other means may be employed to keep the cup stationary. A pro-
Jection K 18 formed on or secuned to the inside of the cup to engage a notch in
the side of the cap and prevent it rotating. As the cup is of large diameter a
concentric hexagonal or polygonal partition V is fixed in it to receive the felt wad.
In Figure 9 tbe stay represented in Figures 4, 5 and 68 shown applied to a cap
spindle and covered by a cap "washer ”T, or the other forms of stay shown may
be used for cap spindles.
Having now particularly described and ascertained the nature of my said inven-
Lion and in what manner the same is to be performed, I declare that what I
claim 18:
1. A spindle stay connected to the lifter plate by a collar formed in the shape
of a portion of a sphere adapted to leave it free to assume a position parallel to
the spindle, substantially as herein shown and described.
2. The combination with a spindle stay connected to the lifter plate, of a
stationary cup surrounding the upper end of the stay adapted to receive a felt
wad and a cap to cover the said cup which cap is provided with means to prevent
it rotating, substantially as herein shown and described.
Dated this 11th day of March 1895.
