PROVISIONAL SPECIFICATION.
Improved Method of Lubricating and Retaining the Oil in the
Bearings of Upright Spindles.
I, JAMES THOMSON, Manager, Walkerton Works, Leslie, Fifeshire, N.B. do
hereby declare the nature of this invention to be as follows:-
This invention relates to an improved method of lubricating and retaining the
oil in the bearings of upright spindles, such as the spindles of flax and other
spinning frames.
In accordance with my improvements I cut a spiral groove round the cone of
the spindle with a well at the bottom end of the groove to catch and retain the oil
when the spindle is at rest. The spindle revolves in a brass or other bush, the
groove being cut in the opposite direction to that in which the spindle turns, the
result being that the spiral keeps screwing the oil up. The brass or bush in which
the spindle revolves may have a plain internal surface, or it may be provided with
grooves or recesses to retain the oil which has been lifted by the spiral. The
spiral arrangements may be applied to plain bearings, as well as to conical
bearings.
By my invention, I have found that oiling once a day is all that is required,.
instead of three times a day with ordinary spindle bearings.
Dated this 12th day of July 1895.

Improved Method of Lubricating and Retaining the Oil in the
Bearings of Upright Spindles.
I, JAMES THOMSON, of Walkerton Works, Leslie, Fifeshire, North Britain,.
Manager, 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 :-
This invention relates to an improved method of lubricating and retaining the
oil in the bearings of upright spindles, such as the upright spindles of flax and.
other spinning frames, and has for its object to save labour and oil and at the same
time provide an efficient lubricating bearing.
In carrying out my said invention, as illustrated in part sectional elevation in
the accompanying drawings, I cut a spiral groove a round the cone 6 of the
spindle B; said groove a having a well A at its bottom or lower end to catch and
retain the oil when the spindle B is at rest. The spindle B is revolved in the
usual manner within the brash or other bush C, which may be formed with a plain.
internal surface as shown, or it may be provided with grooves or recesses to retain
the oil which has been lifted up by the spiral a which is cut in the opposite
direction to that in which the spindle B revolves, so as to enable the spindle B.
while revolving to screw the oil up.

page_text: The improved spiral arrangement may be applied to plain bearings as well as to
conical bearings as shown.
By the employment of my said invention I find that oiling once a day is all
that is required, instead of three times a day with the ordinary spindle bearings
at present in use, owing to the arrangement being such that when the spindle is
revolved the oil is forced up the spiral groove by centrifugal force, and on the
spindle being at rest the oil is retained in the well and so prevented from being
lost as also from dirtying the other parts of the machine.
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
claim is :-
1st. The improved method of lubricating, and retaining the oil in, the bearings
of upright spindles, substantially as herein before described and shown in the
accompanying drawings.
2nd. In the bearings of upright spindles, the spiral groove a and well A,
substantially as and for the purposes herein before described and shown in the
accompanying drawings.
Dated this 16th day of March 19ne.
