PROVISIONAL SPECIFICATION.
Improvements in Washers used in Spinning and Twisting Frames to
Separate the Warls from the Travers or Lifting Plate.
I, JOSEPH WALKER, a citizen of the United States, residing at No. 179
Washington Street, Trenton, in the State of New Jersey, United States, Machinist,
do hereby declare the nature of this invention to be as follows:-
:―
My invention relates to improvements in washers used in spinning and twisting
frames, to separate the warls from the travers or lifting plate, and has for its object
a means of readily keeping the bearing surfaces of the washers, warls and tubes
thereof and also the spindles well and constantly lubricated, without the frequent
manual operation heretofore practiced.
My invention consists of a metallic washer containing a lubricating chamber,
which I fill with a fibrous packing that serves to hold a lubricant and to distribute
it at the proper points, and which washer is accessible for the purpose of lubricating
it without raising the warl therefrom.

COMPLETE SPECIFICATION.
Improvements in Washers used in Spinning and Twisting Frames to
Separate the Warls from the Travers or Lifting Plate.
I, JOSEPH WALKER late of 179 Washington Street and now of 426 Elmer
Street, Trenton, State of New Jersey, U.S.A. Machinist, 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:-
My invention relates to improvements in washers used in spinning and twisting
frames to separate the whirls from the lifter-plates, and has for its object a means
of readily keeping the bearing-surfaces of the washers, whirls, and tubes thereof,
and also the spindles, well and constantly lubricated without the frequent manual
operation heretofore practiced.
My invention consists of a metallic washer formed of a single piece and containing
a lubricating-chamber which may be filled with a fibrous textile or other packing,
which serves to hold a lubricant and to distribute it at the proper points.
In the drawings,
Figure 1 is a vertical sectional view of my improved washer in place and of the
parts of a spinning-frame with which it is immediately connected.
Fig. 2 is a front elevation of the same.
Fig. 3 is a perspective view of my improved washer, and
B is the lifter-plate.
CC are lifter-pins.
Dis the spindle; E, the whirl; F, the tube; G, the cap; H, the washer; 1, the
strap or belt which transmits the rotary motion to the whirl, and J the bobbin.
Spinning-frames, as is well known, are usually built for the winding of numerous
bobbins at a time. These bobbins rest upon the metal whirls and rotate with
Paina 27

page_text: them. The whirls revolve upon the spindles and are supported and raised and
lowered by the lifter-plate, so that the yarn is wound regularly upon the bobbins,
being brought to its position on the bobbin by the stationary cap mounted upon the
spindle, and marked G in the drawings. To these whirls power is trasmitted by a
small belt passing over the driving-wheels of the machine, and they are rotated at
a high rate of speed-usually about seven thousand revolutions per minute; and to
prevent their wearing away that part of the lifter-plate in contact with them,
ordinary metallic ring washers have been heretofore placed upon the spindle
intermediate the whirl and the lifter-plate. Frequent lubrication of the spindle
upon which the whirl rotates and at the bearing-point of the whirl and washer is
requisite, and at each lubrication it is necessary to raise the whirl by hand or
otherwise from the washer, in order to deposit the lubricant at the proper point.
This has to be done several times daily to every whirl in operation, and requires
much labor and attention. By the use of my improved washer much of this labor
is obviated, a considerable portion of the lubricant which by the old process is
wasted is utilized, and the whirls and spindles are more thoroughly and certainly
lubricated, and their life is prolonged.
My improved washer (shown in full size in Figs. 3 and 4) is made to best
advantage of one piece of metal, preferably cast-steel or malleable iron. Through
the middle of the washer and opening in each face thereof is an annular opening,
(shown at a in Figs. 3 and 4,) through which the spindle passes, fitting closely.
The top of the wall of the annular opening is a little lower than the top of the
outside edges of the washer, and is faced to afford smooth play of the whirl, which
rests thereon. The interior of the washer is chambered, as shown at c c in Fig. 4.
This chamber is square, or nearly. so, in plan, and opens to its full width by a
mouth on the upper face of the washer, (shown at 6). The chamber c c opens
into and around the annular opening a, as shown in Fig. 4. This chamber contains
a packing, made preferably of soft fibrous or textile material, which is readily
permeable by lubricants, and which operates to hold the same. The packing is
introduced into the chamber through the mouth b, filling both the chamber and the
mouth, so as to be readily withdrawn and replaced, and has near its centre a
puncture which registers with the annular opening a when the packing, is in place
in the chamber. The upper face of the washer is hollowed out or recessed between
the exterior walls and the wall of the annular opening a, as shown in section in
Fig. 4. In the hollowed or recessed portion of the face are one or more small
openings e e e e, (shown in Fig 3), which open into the chamber c c.
When the washer is to be used, the packing is inserted into the chamber until
the hole in the packing registers with the annular opening a and the outer end of
the packing is readily accessible at the mouth b. The washer is then placed upon
the spindle D and brought to its seat on the top of the lifter-plate, the small arm
or hook f being placed on the inner side of the lifter-plate to hold the washer in
position and prevent its being rotated by the whirl. The whirl E is then passed
down on the spindle until it rests on the top of the smooth upper face of the wall of
the annular opening a. The bobbin and cap are then adjusted. Lubricant is then
poured in upon the recessed upper face of the washer and passes in part through
the openings e e e e and is taken up and held by the packing. This packing being
in contact with the spindle keeps it lubricated, while the spindle in turn keeps the
tube lubricated, and more or less of the lubricant finds its way to the point of
frictional contact between the whirl and the washer.
Having now particularly described and ascertained the nature of, my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :
1. A washer for supporting the whirls of spinning and twisting machines,
consisting of an interiorly-chambered metal plate for receiving packing for
holding and distributing a lubricant upon the spindle and whirl substantially as
described.

page_text: 2. A washer for supporting the whirls of spinning and twisting machines,
consisting of an interiorly-chambered metal plate, and having a packing within said
chamber to hold and distribute a lubricant upon the spindle and whirl, and a
vertical annular passage through the plate for the spindle, said passage having a
connection with said lubricating-chamber, substantially as described.
3. A washer for supporting the whirls of spinning and twisting machines,
consisting of an internally-chambered metal plate having a central vertical
annular aperture for receiving the spindle, and a mouth or opening into the chamber
for the introduction of a packing into said chamber, the plate having a recessed
upper face and one or more openings from said recessed face into said chamber,
substantially as described.
