Improvements in Machinery for Roving, Reducing, Spinning, and
Twisting Fibrous Material.
1, 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 its object is to adapt the lifter plate to afford support to the
spindles without altering the form of the bobbins employed.
The
For this purpose I enlarge the spindle holes through the lifter plate and fix stays
to the lifter plate to fit the spindles. The periphery of these stays may be in the
form of a portion of a sphere or a spherical collar may be formed upon them. The
spherical portion is partly let into the lifter plate and may be retained in position by
a cap. Or the stays may be fixed in position by an external nut below, or by thin
radial projections above the lifter plate or in any other convenient manner.
top of the stays may pass through the usual lubricating washer and be flush with
the top, or, as for instance in cap spinning machinery, it may finish below the top
of the washer. One or more radial oil ducts, preferably inclined downward towards
the spindle, may be formed through the stays for the purpose of conducting the
lubricant from the felt wad in the washer 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.

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 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 that class of machinery for roving,
reducing, spinning and twisting fibrous material in which the spindles pass through
a lifter plate, and its object is to adapt the lifter plate to afford support to the
spindles without altering the form of the bobbin employed.

page_text: For this purpose I enlarge the spindle holes through the lifter plate and fix stays
to the lifter plate, to fit the spindles. The stays may be fixed in position by an
external nut below, or by thin radial projections above the lifter plate or in any
other convenient manner. The top of the stays may pass through the usual
lubricating washer and be flush with the top, or, as for instance in cap spinning
machinery, it may finish below the top of the washer. One or more radial cil ducts,
preferably inclined downward towards the spindle, may be formed through the stays
for the purpose of conducting the lubricant from the felt wad in the washer to the
spindles. Or
a portion of the stay may be cut away to bring the wad in contact
with the spindle to clean and lubricate 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
in each of the figures.
Figure 1, represents an elevation of a portion of a cap spindle with the lifter
plate in cross section showing my improved stay applied to it.
Figure 2, represents an elevation of a portion of a fly spindle with the lifter
plate in cross section showing my improved stay applied to it.
Figures 3 and 4 are similar views showing slight modifications.
Figures 5 and 6 are respectively an elevation partly in section and a plan view
of the stay shown in Figure 2.
Figures 7 and 8 are respectively an elevation partly in section and a plan view
of the stay shown in Figure 4.
Figure 9, represents the form of wad preferably employed with the stay shown
in Figure 4.
Figure 10, represents a plan view of a portion of the lifter plate illustrating a
modified method of attaching the stays to the lifter plate. Figure 11, represents a
side view of the same.
The stay A shown in Figure 1 projects above the lifter plate B to the top of the
recess C in the lubricating washer D but does not pass through this washer. In
Figure 2, however, the stay A is arranged to pass through the cast iron washer D
and be flush with the top and in Figure 3 it also passes through or approximately
through the top of the wooden washer D³. The stays are each formed with a
shoulder a to bear upon the top of the lifter plate B and are held in position by the
nut E screwed on the bottom against the underside of the lifter plate. The stays
are each provided with one or more oil ducts e to convey the lubricant from the
usual felt wad contained in the recess C to the spindle G.
The stay A shown in Figures 4, 7 and 8 does not pass through the washer D* and
instead of the ducts e a portion of the top of the stay is cut away thus exposing the
spindle G on that side to the felt wad in the recess C. In this case the wad is
made with a dee shaped hole so that the flat side H is in contact with the
spindle.
In Figures 10 and 11 a stay is represented having three radial projections A2
secured to the top of the lifter plate by the small screws i. This method of attachment
is not so cheap as that previously described but it enables the stay, in case the top
of the lifter plate is not sufficiently true to hold the stay parallel to its spindle, to
be " set parallel therewith by more or less bending one or more of said
projections.
"
Letters Patent No. 8201 A.D. 1893, and No. 2255 A.D. 1894, have been
granted to me for the particular form of the washer D, D2, D3 and D and I prefer
to use them but it is obvious that other forms may be used.
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 :
A spindle stay for roving, reducing, spinning, and twisting spindles not supported
at the top, consisting of an attachment to the lifter plate fitting the spindle and
provided with a projection above adapted to be surrounded by a felt wad or the

page_text: like and having a duct or the like to convey the lubricant from said wad to the
spindle, substantially as herein shown and described.
