Our improvements in machinery for spinning twisting and doubling fibrous
materials have for their object to provide a better bearing for and lubrication of the
revolving winding parts of such machines and great steadiness with a high speed
and otherwise to improve the said machines as hereinafter described. For cap
spinning twisting and doubling frames we provide a special bearing for the
positively driven wharve tube to revolve on-The said special bearing surrounds the
cap spindle and is formed with or connected at its lower part to a cup like seating
the said cup like seating being fixed to the collar rail or to the bobbin plate. The
said cup-like seating constitutes an oil well and in this oil well a loose washer or
loose washers may be placed to form a bearing for the lower end of the wharve
tube-The said wharve tube at top may extend beyond the aforesaid special bearing
so as to give space in the said wharve tube for a bush or filling piece to prevent oil
from escaping at the upper part of the tube. Oil being placed in the oil cup when
the parts rotate the said oil is carried up between the wharve tube and its special
bearing and to facilitate this ascent of the oil a belical or screw like recess or
recesses may be cut or formed in or on one or other or both of the opposed surfaces
up which the oil mounts
It is preferred in order to lessen friction between the wharve tube and its special
bearing that they be not in contact throughout their whole length. To prevent oil

page_text: from flowing out at the top of the said special bearing a reverse screw like recess
may be provided for a short distance at the upper end of either the wharve tube or
its special bearing (or both) to direct the oil downwards.
In order to prevent the materials when revolving round the cap from bulging
outwards to too great an extent there may be a ring surrounding the said cap and
concentric therewith-These rings may be fixed to any convenient part of the
machine and they may be hinged or otherwise arranged so as to be capable of being
readily turned back or removed when desired.
A ring may be employed at the upper part of the aforesaid special bearing to
steady the wharve tube and this ring may be a split spring ring which may be
sprung into a recess in the aforesaid special bearing. There may be one or more
such rings.
For ring spinning the parts may be arranged substantially in the manner
herein before described a ring and traveller being used instead of a cap. The cap
spindle might however be retained if desired to gain greater steadiness
In fly spinning the parts may also be arranged substantially as hereinbefore
described and the flyer may be fixed on the top of the wharve tube.
When the Invention is applied to ring and flyer frames as the lower part of the
interior of the special bearing may be closed the oil may be allowed to return
to the oil cup by passing at top to the interior of the aforesaid special bearing and
out by an opening or openings in the lower part of the said bearing back into the
oil cup
Dividing plates may be provided between adjacent caps flyers or wings to properly
confine the material being operated upon
The herein before described special bearing may also be applied to twisting and
doubling frames in which no cap flyer or ring is employed and generally to such
other frames as it is or may be applicable to

by the said John Bonny Dewhurst, Thomas Henry Dewhurst, and Robert
Cornthwaite in the Great Seal Patent Office on the 16th May 1883.
JOHN BONNY DEWHURST, and THOMAS HENRY DEWHURST of the Firm of John
Dewhurst and Sons of Skipton in the County of York and ROBERT CORNTHWAITE
of the same place Manager "IMPROVEMENTS IN MACHINES FOR SPINNING
DOUBLING AND TWISTING FIBROUS MATERIALS
Our Improvements in Machinery for spinning twisting and doubling fibrous
materials have for their object to provide a better bearing for, and lubrication of,
the revolving winding parts of such machines so as to produce great steadiness
with a high speed and otherwise to improve the said machines as hereinafter
described. For this purpose in spinning twisting and doubling machines known as
cap frames and ring frames or ring throstles we provide a special bearing (formed
and arranged in connection with the other parts as hereinafter described) for the
positively driven wharve tube to revolve on.
And in Order that our said Invention may be fully understood we shall now
proceed more particularly to describe the same and for that purpose shall refer to
the several figures on the annexed drawings the same letters of reference
indicating corresponding parts in all the figures.
Figure 1 represents a spindle and bobbin of a cap frame to which our Invention
is applied. The special bearing A hereinbefore referred to surrounds the Cap
spindle and is formed in one with a cup like seating B the said cup like seating B
being fixed to the collar rail C or lifter plate. Figure 2 is an elevation of the
parts A and B separate from the other parts. The said cup like seating B
constitutes an Oil well b which may be provided with an annular division wall
forming a space 63 communicating with the space 6 by suitable perforation or
perforations as at as the object being to prevent the whirling or splashing out of
the oil. In the oil well b a loose washer d (or two or more such washers) may be
placed to form a bearing for the lower end of the wharve tube E. The said
wharve tube E at top may extend beyond the aforesaid special bearing A so as to
give space in the said wharve tube E for a bush or filling piece e to prevent oil
from escaping at the upper part of the said tube. Oil being placed in the oil cup b
or space 6 the said oil when the wharve tube rotates may be carried up between
the inner surface of the wharve tube E and the outer surface of the special
bearing A by a helical or screw like recess or recesses of cut or formed in, or on,
one, or other, or both, of the opposed surfaces for the lubrication of the upper parts
of the said bearing, or oil may be applied at the top of the wharve tube and the
helical recess or recesses be dispensed with. It is preferred in order to lessen
friction between the wharve tube E and the special bearing A that they be not in
contact throughout their whole length. To prevent oil from flowing out at the
top of the said special bearing a reverse screw like recess f' may be provided for
a short distance at the upper end of either the wharve tube E or the special
bearing A (or both) to direct the oil downwards. A washer or washers h made
of cloth or other fibrous material may be placed in the annular space b³ to prevent
oil from passing too rapidly into the inner space b. Figure 2 shews the helical
grooves as being upon the exterior of the special bearing. In order to prevent
the materials when revolving round the cap from bulging outwards to too great an
extent there may be a ring surrounding the said cap and concentric therewith.
These rings may be fixed to any convenient part of the machine and they may be
hinged or otherwise arranged so as to be capable of being readily turned back or

page_text: removed when desired. Dividing plates may be provided between adjacent caps
or rings to properly confine the material being operated upon. A bush or ring i
may be employed at the upper part of the aforesaid special bearing to reduce the
friction. The oil cup may be provided with a cover 63. For ring spinning the
parts may be arranged substantially in the manner hereinbefore described a ring
and traveller being used instead of a cap. Figure 3 is a vertical section of a
special bearing and wharve tube as applied to a ring frame the said bearing and
tube serving together the purpose of a spindle..
In this case as the lower parts of the interior of the special bearing may be
closed as shown the oil after passing up between the exterior of the bearing A and
the interior of the wharve tube E by the groove ƒ may be allowed to return to
the oil cup by passing at top through the opening or openings a to the interior
of the aforesaid special bearing A and out by an opening or openings a³ in the
lower part of the said bearing A back into the oil cup b or into the space bª.
Figure 4 represents in vertical section a spindle of a cap frame in which a return
flow of the oil is secured by forming the special bearing with an additional tube A¹
fixed to or fitted upon the part A and leaving a space between the said part A
and the wharve tube E for the ascent of the oil by the helical groove or grooves f
formed on the exterior of the part A or on the interior of the wharve tube or
both. Figure 5 is a separate view of the part A2 and Figure 6 is a section on the
line 1.2 Figure 4. The oil when it reaches the top of the tube A passes thereover
and down the space between the parts A and A* back to the oil cup. Vertical
or helical grooves K may be made at intervals in the part A³ or the part A at the
bearing of the said parts upon one another to allow the oil to readily descend and
holes or openings g may be made through the part A' for the same purpose. In
Figure 5 we have shewn a nick j (of which there may be one or more) which may
be cut at the lower end of the part A³ to facilitate the passage of the oil from the
interior of the said part A².
In Figures 2, 3, 4, 5 and 6 we have marked the parts which correspond with
Figure 1 with the same letters of reference and they will thereby be readily
understood without further description.
Having now described and particularly ascertained the nature of our said
Invention and the manner in which the same is or may be used or carried into
effect we would observe in conclusion that what we consider to be novel and
original and therefore claim as the Invention secured to us by the hereinbefore in
part recited Letters Patent is:―
First The general arrangement and combination of parts constituting the
improvements in machinery for spinning twisting and doubling fibrous materials
herein before described and illustrated in the accompanying drawings.

passage of oil substantially as hereinbefore described with reference to Figures 1
and 2 of the accompanying Drawings.
Fourth-In Cap and ring spinning twisting and doubling frames the combination
of a helical or screw like recess or recesses extending to within a short distance
from the upper end of the wharve tube or special bearing or both for the upward
flow of the lubricant with a reverse helical or screw like recess or recesses formed
at the upper part of the said wharve tube or special bearing or both for preventing
the lubricant from escaping at the upper part of the tube as hereinbefore described
and illustrated in Figure 2 of the accompanying Drawings.
Fifth In ring spinning twisting and doubling frames the combination of a

page_text: special hollow bearing for the wharve tube having a helical or screw like recess or
