PROVISIONAL SPECIFICATION.
Improvements. in the Lubrication of Spindle Bearings Employed in
Machinery for Preparing and Spinning Fibres.
We, BENJAMIN ALFRED DOBSON, Engineer, ROBERT HEWITT ROBINSON,
Foreman, and GEORGE FREDERIC HOUGHTON Head Mechanic, all of Kay
Street Works Bolton, in the County of Lancaster, do hereby declare the nature of
this invention to be as follows:-
.
F
Our invention relates to the lubrication of the footsteps of those spindles which
have their footstep bearing separate from the upper or bolster bearing, and
particularly to spindles which have a cover or washer a short distance above the
footstep bearing, and the object of our improvements is to lubricate footstep bearings
of spindles in an efficient manner.
.
In carrying out our invention we groove the spindle from that part where the
cover or washer is fixed, down to that part of the spindle where it is reduced in
thickness to make the footstep, and we make the cover or washer in the form of
an oil cup, the groove extending far enough up the spindle to conduct the
lubricating oil placed in the cup, down to the footstep bearing aid so lubricate
the same.
•
"
In the case of fly frames where each spindle is driven from a skew gear wheel,
which is again covered by casing boards, the groove will begin in the spindle just.
above the top portion, of the spindle wheel or gear. The surface of this wheel
is preferably slightly hollowed so as to form an oil cup, and in this manner the
whole of the lubricant placed therein may be safely conducted to the spindle
bearing.

We, BENJAMIN ALFREDDOBSON; Engineer, ROBERT HEWITT ROBINSON,
Foreman, and GEORGE FREDERIC HOUGHTON Head Mechanic, all of Kay
Street Works, Bolton, in the County of Lancaster, 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 :-
Our invention relates to the lubrication of the footsteps of those spindles which
have their footstep bearing separate from the upper or bolster bearing, and
particularly to spindles which have a cover or washer a short distance above the
footstep bearing, and the object of our improvements is to lubricate footstep
bearings of spindles in an efficient manner.
In carrying out our invention we groove the spindle from that part where the
loose cover or washer is usually placed, down to that part of the spindle where it

in the form of an oil cup, the groove extending far enough up the spindle to
conduct the lubricating oil placed in the cup, down to the footstep bearing and so
lubricate the same.
In the case of fly frames where each spindle is driven from a skew gear wheel,
which is, again covered by casing boards on the top of which is placed a cover or
washer the groove will begin in the spindle just above the top portion of the
spindle wheel or gear. The surface of this 8, preferably hollowed so as to
form an oil cup, and in this manner the whole 18
the lubricant placed therein may

be safely conducted to the spindle-bearing.
And in order that our invention may be f
be fully understood and readily carried
into effect we will describe the accompanying two sheets of drawings reference
being bad to the figures and letters marked thereon..
Figure 1 is a sectional elevation of the lower end of a spindle driven by a band,
not shown, and its footstep bearing illustrating the application of our improvements
in lubricating the same.

Figure 2 represents the lower ends.of two spindles driven by skew gears, the
spindle and bearing on the left hand being an elevation with part of the cover or
casing removed and that on the right hand being a sectional elevation showing the
interior of the footstep bearing and skew pinion.
In these views, A designates the spindles, A the grooves formed in the spindles,
and A the,, reduced diameter or footstep, B.the footstep bearings, which are
specially formed as, oil reservoirs and C the rail or block which supports the
bearings B.
j.
In Fig. 1 we fix an oil cup D with a screwed or other cap D' on the spindle A
instead of the usual cover or washer, so that the lubricant poured into the cavity
in the cap D¹ or placed in the oil cup D'finds its way down the groove or
grooves. A into the footstep bearing B and so lubricates the same.
In Fig. 2. the oil cup is formed within the skew pinion D by which each
spindle A is om a skew, wheel' E the parts being covered by a casing F
with a loose
or cover G placed over the hole in the top of the casing. To
lubricate the spindle the cover or washer G. is, removed and the oil is poured into
the hollow of the pinion D the cover or washer is then replaced and the oil
descending by the groove or grooves A¹ lubricates each footstep bearing B in
identically the same way as in Fig. 1.

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 :-
In combination the grooved spindle A, the hollow footstep bearing B and the
oil cup D all substantially as and for the purposes herein described and as illustrated
by the accompanying drawings.
