Specification Accepted, 23rd Feb., 1889
We GEORGE PETER LEIGH of 147 Great Ancoats Street Manchester in the County
of Lancaster Mill Manager, and ARTHUR HENRY BELLRINGER of Enschede, in the
Kingdom of Holland 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 :-
The objects of our invention are to reduce friction, and wear, and to promote the
steady running of the spindles at high velocities, and at the same time to economize
cost of manufacture and working.
The nature of our said invention and the manner in which the same is to be performed
or carried into practical effect will be readily understood on reference to the annexed
sheet of drawings and the following explanation thereof.
Fig. 1. on the drawing is a front elevation and Fig. 2. a transverse section of part
of the spindle rail and bolster rail of a mule carriage showing the application of our
invention thereto.
Fig. 3. is a transverse section illustrating a modification thereof and Figs. 4. 5. 6. 7. 8
and 9. are detached views hereinafter more particularly referred to.
་
a is the spindle rail, the bolster rail, and c the spindles. We dispense altogether
with the footsteps and bolsters usually employed as bearings for the spindles. We
make a groove from end to end in the upper surface of the spindle rail, and we insert
therein a box or trough d of metal to contain the oil or lubricating material. In this
box d lies an angle plate e (shown also detached at Fig. 9.) which may be made of
steel or other suitable metal but we prefer phosphor bronze.

page_text: The horizontal limb of this angle plate supports the foot or point of the spindles
and the vertical limb thereof acts as a bearing plate against which the side of the
spindle foot revolves, being held against it by the "pull" of the spindle band which
passes round the wharve f
In front of the bolster rail b we support by means of hangers or brackets ga
similar lubricating box or trough h but in this case the bottom of the box is drilled
for the passage of the spindles c through the same, and the bearing plate i is a plain
plate (see face view Fig. 8) instead of an angle plate as in the lower box.
Each of these lubricating boxes is covered by a removable plate k k¹ accurately
drilled so as to preserve the perpendicularity and gauge of the spindles, and this plate
also acts as a cover to prevent the admission of dust or fluff into the lubricating box,
(see also plan views Figs. 6 and 7).
We prefer to make the front plate of the lubricating boxes in the form of a separate
plate let into grooves so that it can be removed for cleaning out the box without
taking off the top, or doffing the cops.
And in order to equalize the friction at the upper and lower parts of the spindle,
instead of making the foot of a smaller diameter than the upper bearing part, as
hitherto practised, we prefer to make both the upper and lower bearing. parts of the
spindles of the same diameter as shown on the drawings.
It will be evident that by the use of our invention the friction (and consequently
the wear) will be reduced to a minimum as the spindles only touch the bearing plates
at a single point of their circumference; that the lubrication will be perfect, and the
lubricant will not require renewing excepting at long intervals, that no dirt or fluff
can get into the lubricating boxes, and that if any impurities from the lubricant should
accumulate therein they can readily be removed."
We would here remark that the upper or bolster lubricating box when made as
shown at Fig. 2. will only answer for semi-solid lubricants, such as that called
"solidified oil" for example, but if it should be desired to adapt our principal for the
use of fluid oils it may readily be done by soldering in each spindle hole in-the-bottom-
of the upper trough, a thin metal bush or bolster in place of the bearing plate as
shown at Fig. 3. accurately drilled to fit the spindle and either split or perforated to
allow of the access of the lubricant to the spindle.
Whenever the bearing plates e or i show any signs of wear, new bearing surfaces
may be brought into action by simply sliding the said bearing plates end wise (say)
about one eighth of an inch and thus the wearing surfaces may be renewed several
times without changing the plates.
In some cases we propose, instead of having flat bearing plates to make them
with curved recesses m to fit each spindle as shown at Figs. 4 and 5, or the recesses
may be made angular if preferred but in this case it is obvious that the bearing surfaces
cannot be renewed when worn by sliding the plates end wise.
Instead of having a long lubricating box as above described we propose sometimes
(especially when the spindles are spaced widely apart) to modify our invention by
having a separate lubricating box d¹ for each spindle (see Fig. 10.) fixed to the front
of the spindle rail, the back of the box d' forming the bearing plate against which the
spindle revolves, the remainder of the spindle being entirely open to the grease or
oil as in the case of the long box. In this modification no additional bearing plate
is required.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
First the method of and apparatus for mounting, supporting and lubricating the
spindles of mules winding frames and twiners substantially as, and for the purposes
herein before particularly set forth and illustrated by the drawings annexed.
Secondly we claim the combination of the longitudinal lubricating boxes with flat
or corrugated bearing plates for such purposes.

page_text: Thirdly we claim the modification of our invention illustrated by Fig. 10. of the
drawings, and
J
Fourthly we claim the construction of spindles with the foot and bolster bearing
part of equal diameters for the purpose of equalizing the friction at both the footstep
and bolster.
