PROVISIONAL SPECIFICATION.
Improvements in and appertaining to the Spindles of Cap and Ring
Spinning Machines.
I, STEPHEN THOMAS SHARP, of Oakworth, near Keighley in the County
of York, Mechanic, do hereby declare the nature of this invention to be as
follows, that is to say :-
It relates to Improvements in and appertaining to the Spindles of Cap and Ring
Spinning Machines and consists of forming or constructing these spindles and the
parts that operate in connection with them in such a manner as to avoid any
vibration of the spools or bobbins when rotated at a high rate of speed, while at the
same time thorough lubrication of the parts is effected.
In accordance with one arrangement I arrange the fixed spindle to have a cavity
formed concentrically around it, into which a projecting sleeve from the driving
wharve or pulley is made to pass and operate, this cavity being for the reception of.
the lubricant which is allowed to circulate within it and into contact with the
stationary spindle and rotary sleeve by means of an opening being made for its
passage through the latter.
On the other side of the wharve I form another sleeve which carries at its upper
end suitably formed coupling pins which take into slots formed in the rim of the
tube mounted above it upon the stationary spindle.
This tube extends through the lifter plate and has longitudinal furrows or key
ways made in it for the reception of projecting pieces formed on a flange which
takes over it. This flange being formed, by having appropriate spring-clips
attached to it, to receive and lay hold of the spool or bobbin taking over it, by
which means as the tube rotates, this flauge is also rotated in addition to its vertical
reciprocatory motion imparted by the lifter plate. The tube being of sufficient
length to allow such vertical motion while suitable cup shaped attachments secure
the bobbin's supporting-flange so that it will move as the lifter plate moves and be
properly lubricated by the lubricant placed in this cup-shaped attachment.
By the employment of the parts constructed as above described, the bobbins are
held from vibrating, the parts are efficiently lubricated, and the driving wharve or
pulley is maintained at all times in one plane thus the driving band or cord is
always in one state of tension without the employment of the well known tension
pulleys.
In accordance with another arrangement the driving wharve or pulley is attached
in the usual manner to the tube carrying the spool or bobbin.
However in this case, I make the downwardly projecting sleeves, double, the
inner one in contact with the stationary spindle being made to reach its bearing
or support at the bottom around which a cavity or receptacle is formed for the
lubricant. The bottom of such cavity being lower than the part supporting the
sleeve so that any sediment or precipitate from the lubricant is allowed to fall out
of the way of such bearing.
This inner sleeve has a spiral groove formed in its outer surface, while a tube or
sleeve carried by or attached to the cavity containing the lubricant takes over this
inner sleeve of the wharve, so that as this latter rotates, the lubricant is caused to
flow up the spiral groove, over the top of this tube and back into the receptacle
beneath. Small holes being made through this inner sleeve to allow a certain
portion of the lubricant to come into contact with the stationary spindle.
Instead of the spiral groove being formed on the outer surface of the inner
sleeve it may be formed on its inner surface while lateral openings are made at the

page_text: top of such sleeve to allow the lubricant to pass through on reaching this position,
thus it is enabled to flow up the space intervening between the inner sleeve
and its stationary support and down' back on the outside of said sleeve into the
receptacle.
When this formation is employed the tube attached to the fixed bearing is some-
what shortened, its length being only sufficient to reach within a short distance of
the outer sleeve on the wharve so as to prevent excessive agitation of the lubricant
within the cavity.
The outer sleeve on the wharve takes over the tube attached to the cavity or
bearing in order to prevent the lubricant from being thrown out of the receptacle,
while a flange formed around the extreme edge of the wharve extends over
the intrusion of small fibres, dust, dirt or other foreign matter.

Improvements in and appertaining to the Spindles of Cap and Ring
Spinning Machines."
I, STEPHEN THOMAS SHARP of Oakworth near Keighley in the County
of York, Mechanic, 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, that is to say :—
It relates to Improvements in and appertaining to the Spindles of Cap and Ring
Spinning Machines and consists of forming or constructing these spindles and the
parts that operate in connection with them in such a manner as to avoid any vibration
of the spools or bobbins. when rotated at a high rate of speed, while at the same
time thorough lubrication of the parts is effected.
In order that my said invention may be more readily understood, I have hereunto
appended a sheet of drawings illustrative thereof to which by figures and letters,
reference is made in the following description.
Fig. 1 is front elevation of my improved parts, as seen when a bobbin is mounted
thereon.
Fig. 2 is a similar view without said bobbin.
Fig. 3 is a vertical section enlarged scale of the parts shown by Fig. 2.
Fig. 4 is a top view of a part hereinafter described.
Figs. 5 and 6 are sectional views, same scale as Fig. 3, and illustrate alternative
forms hereinafter described.
Fig. 7 is a cross section on line A B of Fig. 6.
Figs. 8 and 9 are sectional details hereinafter referred to.
In accordance with my invention I arrange the fixed spindle a to have an annular
cavity & formed around it, into which a projecting sleeve c from the wharve d is made
to pass and operate, this cavity b being for the reception of the lubricant which is
allowed to circulate within it and into contact with the stationary spindle u
and rotary sleeve c by means of openings e made for its passage through the
latter.
On the other side of the wharve d I form another sleeve
upper end suitably formed coupling pins 9 which take into slots
in the rim k¹ of the tube k mounted above it.
which carries at its
(see Fig. 4) formed
This tube extends through the lifter plate m and has longitudinal furrows or
key-ways m¹ made in it for the reception of projecting pieces formed on a flange n
which takes over it. This flange n is formed, by having appropriate spring clips
attached to it, to receive or lay hold of the spool or bobbin o' taking over it, by
0

page_text: which means as the tube k rotates, the flange n is also rotated in addition to its vertical
reciprocatory motion conveyed to it by the lifter plate m, so also is the bobbin o'
rotated and otherwise moved as and by the said flange n.
By the employment of the parts constructed as above described, the bobbins o' are
held from being vibrated by any irregular pull or force of the driving band on the
wharves d since such irregular or vibratory force of the band will only affect said
wharve d, the loose attachment between which and the tube k allowing same without
conveying this motion to the tube or bobbin, while all the parts are efficiently
lubricated and the wharve d is maintained at all times in one and the same plane
thus the driving band is always in one state of tension without the employment of
the well known tension pulleys.
In accordance with another arrangement of my improved parts, the driving
wharve d is fixed in the usual manner to the tube k. However in this case I make
the downwardly projecting sleeves cl c¹¹ double as shown by Fig. 6, the inner
one c¹ being made to reach to its bearing or support d' at the bottom around which
the cavity b is formed, the bottom, of this said cavity b being lower than the part d'
so that any sediment or precipitate from the lubricant is allowed to fall out of the
way of such bearing.
This inner sleeve c¹ may have a spiral groove formed on its outer surface,
while a tube p carried by or attached to the part forming the cavity b, takes
over this said sleeve c', so that as it rotates the lubricant may be caused to
flow up the spiral groove over the top of this tube p and back into the receptacle b
beneath.
Or the spiral groove may be formed on the inner surface of the sleeve c¹ as shown
by Fig. 6, while lateral openings 2 made in the sleeve c¹ allow the lubricant to flow
through on being raised by the actions of the said spiral groove so that all of these
parts are thoroughly lubricated.
When this formation is employed the tubes attached to the part 6' which in this
case is carried by the lifter plate m through which the spindle a passes loosely is
preferably made to extend through the wharve d for contact at its upper end with
the lower end of the tube k while the sleeve c¹ rests on the bearings d' as shown
by Fig. 5. The cavity b with a loose protecting covert being in this case also
made use of, by which means the parts are thoroughly lubricated while the inner
tubes forms a good resistance for the pull of the driving band conveyed through the
wharve d.
Instead of the tube k being attached rigidly to the wharves d, the method of
attaching them loosely thereto as hereinbefore described may be followed, or this
loose attachment may be effected by the tubek having lateral projections u with
intervening spaces between them for projections ¹ on a flange or cap v to enter so
that on this latter being secured by screws w or other means to the wharve d, (or
for this flange a ring a fitting tightly within the opening in the wharve d may be
employed, the necessary projections or openings being formed on or in it as shown
by Figs. 8 and 9) the rotary motion of this latter may be conveyed thereto although
this joint allows slight lateral play or side shake for the tube.
The flange party of the wharve d takes over the tube forming the cavity b
in order to prevent the lubricant from being thrown out of the said receptacle as
also to prevent the intrusion of small fibres, dust, dirt or foreign matter.
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
clain is ;-
1. The combination of a stationary spindle, wharves having longitudinal
projecting sleeves, bearings for and arranged to extend within such sleeves and
wharves and tubes attached to said parts substantially as herein set forth and
described.
2. The combination of a stationary spindle, a wharve mounted to rotate on
said spindle, bearings constructed to receive the lubricant for said parts, a

page_text: tube loosely attached to said wharve and otherwise formed so that the bobbin
taking over it may have reciprocatory as well as rotary motion conveyed to it
substantially as specified.
3. The combination of a stationary spindle, a lubricating device carried by
the lifter plate, this device also acting as a support for the wharve and tube, and
said wharve and tube the latter being attached to the former substantially as set
forth.
4. The method of forming wharves and tubes and means for supporting and
¡lubricating same substantially as herein set forth and described.
