Improvements in Spindles and Spindle Collar Bearings or Bolsters
Used in Preparing, Spinning, Doubling, Twisting, and Winding
Cotton, Wool, Flax, Silk, and other Fibres.
WILLIAM SUMNER, Almelosche Spinnery Almelo, Holland, Spindle Maker 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:
2:
To Spindles and their Collar bearings, or bolsters, "I refer to both fixed and driven
collar bearings which have been in use and wore slack or loose more or less variable
at the external bearing part of the spindle, and at the internal part of the collar
bearing or bolster, and which permits vibration of the Spindle when at work. I
reduce the Spindle at its bearing part, or at its traverse part of the bearing, to a round
surface and uniform in thickness throughout its length of bearing or traverse length
of its bearing, and I apply a bush, tube or lining of phosphor bronz, nickel silver or
of other alloy bearing metal, to the inside of the old Collar or bolster bearing, this
bush I construct so that the outer surface of the bush fits the internal part of the old
Collar or bolster "and to Preparing frames" the bush can fill also a portion of the hole of
the bobbin, and the inside of the bush fits freely but firmly in circumference the
reduced bearing part of the spindle, 1 also apply these bushes to new or old preparing
frames known as-Jack, Roving, Intermediate and Slubbing frames" short collar
bearings, which have new spindles applied to the them, for the purpose of preventing
the spindle from wearing so much as hitherto when the spindle works in Cast Iron
Collars, these short collars, at its upper part I prefer to countersink "or dish"
reces or reservoir for the lubricant, and a reception of sediment, the bush I form with
a hole or side opening at or near its top to allow the lubricant to pas to the spindle,
also the bushes for spindles that have been reduced at bearing part only, I prefer to
make thinner or weaker at or near the full length of the bush, to permit the bush to
pass over the unreduced part of the spindle see Drawings.

In order to make this my Invention, understood reference is made to the accom-
panying Drawings in which the improvements is represented, or shewn, under various

page_text: aspects, and in which similar letters, refer to similar parts, and all the parts are drawn
to very near full size.

reduced bearing part of the spindle-b, the attached or fixed frame rail Collar-c the
Collar bush-d, a loose shell hoop or collar "g to run with the bobbin to prevent 5
the bottom of the bobbin from vibrating, (this loose shell hoop is not required if the
bobbin wheel is dished or recessed at its top as shewn at-i, so as to receive the
bottom of the bobbin which will prevent the bobbin from vibrating at its lower end,
sometimes I make the collar bush d not to come higher than the top of the bobbin
wheel, also sometimes I connect the top of the bush with the top of the bobbin wheel
by means of a connecting pin at-k, or by other mechanical means, which causes the
bush-d, to revolve with the bobbin wheel-f-around the spindle bearing b.

have loose internal driven spindle collars, The spindle a, the reduced bearing part of
the spindle, the outer (frame rail) attached Collar & the (internal) Collar bush d, the
driven inside Collar e which is driven by a connecting pin to, or in, the bobbin
wheel-

Fig. 3 shews as what is known as a lug Collar c, to fasten to the top of a frame rail
which have no Collar lugs formed thereto; and a bush d and a loose revolving hoop y
for the bobbin bottom to enclose and drag with it.
Fig. 4 shews an end view of my bush d (size as used in Preparing frames) at-h
it is shewn to be made thinner so that when the bush is passed over the full part of the
spindle a,
the bush opens from the weaker part, and when placed within the collar c
closes from the same weaker part, thus returning to its first formed round shape, the
inner surface fitting the reduced part of the spindle b, and the outer surface fits the
inside surface of the frame or machine collar or bolster.
Fig. 5-shews a front view of my bush for preparing frames collars and
spindles.
Fig. 6-shews as a front view of of a collar c, and my bush-d for use in Throstle
Doubling or Winding frames, which have stationary collar rails.
Fig. 7-shews a front view of my bush-d "as" for use in Mule, Twiner "or
Twisting" frame collars or bolsters, and spindles.
Fig. 8 and Fig. 9-shows front view of my bush-d as for use in Ring and
Throstle frame collars which have had worn spindles reduced at their bearing
part.
Fig. 10-shews a Rabbeth spindle (without its sleeve or warve) after being reduced
at its previously worn bearing part-b, from the full size of the unworn part of the
spindle-a the bush-d is increased in thickness so that its outer surface fits the
inside of the frame tube or bolster, and the inside of the bush fits the reduced bearing
part of the spindle.
Fig. 11-shews a portion of a Mule, or a Twiner (twister) spindle-a, the spindle
bolster c, and my bolster bush—d.
Fig. 12-shews a Throstle, Doubling or Winding frame Spindle to be used in frames
which have a stationary collar rail, the spindle-a-the spindle collar-c and the
collar bush-d.

frames having lifting Collar rails, the reduced bearing part of the spindle a-the
frame collar-c and the collar bush-d, and a loose hoop or shell-g.
The advantages of my arrangement of reducing irregular worn spindle bearings,
and applying my bush to fill up the space between the reduced part of the spindle
bearing and the Collar or bolster, are (or is) I retain in use the old spindle, the old
frame collar or bolster, and the bobbins, thus reproducing at little cost, a good and
durable fit to spindle, and Collar or bolster,-to frames or machines, making the
spindle capable of running steady at the highest possible speed. Also to new or old
preparing frames, and mule or twiner or twisting machines the application of my
bushes to their collars or bolsters wherein new Spindles are applied, I find much
longer preserves the spindle from wear, and tends to longer retain the spindle

page_text: steady. I reduce the spindle bearings by grinding, turning or other mechanical
means.
Having now particularly described and ascertained the nature of my said
Invention and in what manner in which the same is to be performed, I declare that
what I claim is―
Firstly reducing old spindles at their bearing, or Collar part for the purpose of
making the bearing, collar or bolster part, round and uniform in size (or nearly so
throughout the spindle or spindles in, the frame or machine, and to be used within
a bush, fixed, attached or placed within the frame or machine Collar or bolster,
substantially as hereinbefore described and shewn in the drawings.
Secondly in making and applying a bush or lining to be fixed or attached within
the old frame collars or bolsters, that are to be used upon spindles that have been
reduced at their bearing or holster part, by grinding turning or other mechanical
means, substantially as herein before described and shewn in the drawings.
Thirdly in making and applying, bushes to new or old Preparing frame short
collars, also to mule and twiner (twisting) frame bolsters within which new spindles
are to be used substantially as herein before described.
