Improvements in connection with Spindles for Spinning and like
Machines.
I, EMILE MAERTENS of the Narragansett Hotel, Providence in the State of
Rhode Island, United States of America, Manufacturer, do hereby declare the
nature of this invention to be as follows:-
My invention relates to improvements in ball-bearings or supports for live-
spindles, employed in spinning and twisting machines, and it has for its object to
provide means whereby the spindles may be operated by less power; or, in other
words, the working friction is greatly reduced, from the fact that the bearings are
prevented from clogging up with dust, lint, etc.
By means of my improvement I am enabled to not only save a large portion of
the power which is usually required, when such live-spindles or revolving sleeves
are supported by stationary or fixed bearings, but at the same time the spindles
may be rotated more rapidly, the wool or fibers being operated upon are more
evenly twisted, and the output is correspondingly increased. This result is due
largely to the novel construction of the bearing, whereby dirt, lint, etc., are
excluded.
My invention consists essentially in the application and combination with a
vertically arranged dead-spindle and a rotatable sleeve or live-spindle mounted
thercon, of a fixed bearing, through which the dead-spindle extends, containing a
series of small anti-friction balls, a suitably centered rotatable cap or plate resting
upon said balls provided with an oil-duct, and a central washer snugly recessed into
or otherwise attached to said cap and concealing the oil-duct, whereby the bearing
is kept free from dust, fly-lint or other dirt or foreign matter, and allowing the
spindle, etc., to be freely rotated with a minimum consumption of power.
In carrying out my invention I may employ a dead-spindle, so-called, a live-
spindle or revolving sleeve, a spindle-rail, and a lifter-plate through which the
dead-spindle passes, all substantially as usual. The bearing proper, forming the
improvement, is provided with a stationary base piece or disc having a groove in
its upper face in which groove a series of anti-friction balls are located. The
central portion of the base has a screw-threaded bushing through which the dead-
spindle passes; said bushing is provided with an enlarged head and a shoulder.
Resting upon the balls is a rotatable cap or plate having its sides extending down-
wardly over the base; this cap is counterbored and is maintained in position both
centrally and vertically by the shouldered portion of the said bushing. The cap is
further provided with a lubricating hole or oil-duct communicating with the ball-
carrying groove of the base, it is also provided with a central washer or plate let
into and snugly fitting a recess formed in its top surface and covering the said
oil-duct. There is a small space formed between the under side of the washer and
the top of the bushing. A lubricating disc is let into the upper face of the lifter-
plate, the ball-carrying base resting upon the former.
In arranging the several parts the dead-spindle extends upwardly through and
in contact with the said lifter-plate, lubricating disc, base-disc, bushing and central
washer. The live-spindle or bobbin-carrying sleeve is adapted to rotate freely
around the center or dead-spindle by means of a band-driven whorl, substantially
as usual. The combined weight of the revolving whorl, the sleeve, the bobbin *

page_text: and its yarn-load are borne by the series of anti-friction balls through the
medium of the interposed cap-plate and its top washer, the two latter members
revolving in unison with the live-spindle.

Improvements in connection with Spindles for Spinning and like
Machines.
I, EMILE MAERTENS, of the Narragansett Hotel, Providence, in the State of
Rhode Island, United States of America, 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 by the following statement and accom-
panying drawings:-
My invention relates to improvements in ball-bearings, so-called, for spindles of
spinning and twisting machines, employed in the manufacture of yarn, etc.
My invention consists essentially in the combination of a ball-carrying base
member adapted to be mounted on the usual lifter-plate, a stationary shouldered
central sleeve or bushing arranged to receive the dead-spindle secured to said base,
a freely revoluble cap or plate resting upon the balls provided with an oil-duct
and in engagement with the shouldered portion of said sleeve, and a central disk or
washer fixed to said cap and concealing the oil-duct and bushing and capable of
rotation with the cap, all as will be more fully hereinafter set forth and claimed.
I am aware that ball-bearings for the spindles of spinning and twisting machines
have been used prior to my invention. Such former devices, however, were
rendered more or less inefficient from the fact that they were unprovided with
means for effectually excluding dust, fly, lint or other dirt or foreign matter,
therefore the advantages normally due to bearings provided with a series of anti-
friction balls were materially lessened, after a comparatively short service, owing
to the presence therein of lint, etc., thereby requiring a correspondingly increased
amount of power for operating the spindles. I am also aware that ball-bearings
for vertical spindles have been made in which a movable central sleeve or bushing
is employed through which bushing the live spindle extends. My invention differs
from such former bearings in that the dead spindle passes loosely through the
bushing, the latter being stationary and so arranged that it is out of contact with
the live spindle at all times.
The object 1 have in view is to practically overcome the objections or
disadvantages inherent in ball-bearings of the class just referred to. By means
of my improvement the bearings are prevented from clogging up with dust,
lint, etc., consequently the spindles may be freely rotated with a minimum
consumption of power.
When the several parts forming my improved bearing are combined together,
thus constituting an article of manufacture, the interior of the bearing, that is the
portion in which the series of small anti-friction bails are mounted, is practically dirt
tight, the balls being completely concealed, thereby excluding dust and other
foreign matter.
In the accompanying sheet of drawings,
Figure 1 is a side elevation, in partial section, showing my improved ball-bearing
mounted as in use.

It
A, again referring to the drawings, designates my improved ball-bearing as a
whole, and as arranged for the spindles of spinning and twising machines.
consists essentially of a round base member a having a V-shaped annular groove g
in its upper face in which a series of anti-friction balls e are located; a screw-
threaded central sleeve or bushing b is secured to the base a, aud a freely rotatable
cap or disk c is supported by the balls e and is held in position by the head of the.
bushing b.
The rotary cap-plate c is provided with a downwardly extending peripheral
rim c', the latter closely surrounding the corresponding sides of the base. The
said cap is counterbored centrally to form the flange c³ and is arranged to receive
and freely revolve around the enlarged flange f and head 62 of the bushing, as
clearly shown in Fig. 5. As thus constructed it forms a practically dirt tight joint
and serves to prevent the entrance of foreign matter. The upper end of the bushing
may be provided with two grooves 6, or other equivalent means, to receive a suitable
tool to facilitate its insertion and removal. The cap c has a thin metal washer or
disk d let snugly into its upper face; said washer is practically one with the cap,
and it covers an oil-duct o formed in the cap. This oil-duct when uncovered affords
means by which the bearing can be easily lubricated. The washer d may be
readily detached from the cap by inserting the end of a suitable pointed tool or
wire into the recess m.
In Fig. 1 my improved ball-bearing is shown as adapted to spindles of spinning
and twisting machines. That is to say, the stationary or dead spindles is adjustably
mounted in a spindle-rail p and passes upwardly through the usual lifter-plate r.
On top of the latter is located my improved ball-bearing A, said spindle also
passing through it. A sleeve or live spindle t is mounted to revolve around the
stationary spindle and is arranged to carry a bobbin or spool as usual. The live
spindle has secured thereto at the botton a belt-driven whorl w; the two latter
revolve in unison as common and rest directly upon the washer portion of the cap-plate c,
which in turn is supported by the stationary ball-carrying base a; the stationary
bushing b at the same time serving to hold the revolving cap-plate in position both
centrally and vertically. From the foregoing it will be apparent that the central
bushing or sleeve b is out of contact with the live spindle and whorl at all times.
I prefer to interpose a lubricating-disk or washer 2 of fibrous material between
the under side of the bearing A and the lifter-plate r, the latter being recessed for
the purpose, as shown. In some cases the bearing may be secured directly to the
dead spindle s, without the intervention of the lifter-plate. In any event the
base a of my improved ball-bearing is to be fixed or stationary while at the same
time the cap-plate member thereof is adapted to be rotated by and in unison with
the live-spindle.

Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is:
1. As an improved article of manufacture, the herein before described ball-bearing
for spindles of cap-spinning and twisting machines, the same consisting essentially
of a base member, a series of anti-friction balls arranged therein, a suitable cover
or cap-plate resting upon said balls and capable of being independently rotatable
with respect to the base member, and a removable central bushing or sleeve
arranged to be out of contact with the live spindle and fixed to said base and
having its head portion arranged to maintain said cap-plate in position, and being
also arranged to receive a dead spindle.
2. In a ball-bearing of the class described, the combination with a circular base

base and having said dead spindle passing therethrough, a cover or cap-plate inter-
engaging with the head of said bushing and supporting the live spindle and capable
of being rotated by the latter, and a series of movable anti-friction balls interposed
between the base member and cap-plate, said balls supporting the latter and the
load resting thereon.
5. In a spinning or twisting machine, the combination with a dead spindle, a
rotatable or live spindle mounted thereon and a lifter-plate, of a ball-bearing device
