We, WILLIAM BUTTERWORTH, of 182 Wellington Street, Bradford, N* Manchester,
Mill Mechanic HAROLD SHAWCROSS, of Woodfield, Rochdale, Cotton Spinner,
& BENJAMIN BUTTERWORTH of 16, Casson Gate, Rochdale, Engineer all in the
county of Lancaster do hereby declare the nature of our invention for IMPROVE-
MENTS IN THE METHOD OF LUBRICATING THE BEARINGS OF SHAFTS, & OTHER
REVOLVING PIECES OF MECHANISM to be as follows:-
At or near the middle of the bearing we form a groove or recess in it, this
recess is made sufficiently large to allow a peg which is fastened into the shaft to
work round in it, and also to form a reservoir for oil or other lubricant; on the
sides of the bearing we form or attach drippers to catch the lubricant as it escapes
from the edges of the bearing, these drippers communicate by suitable holes with
the recess in the middle of the bearing, as the shaft revolves the peg which is
fastened into it dips into the lubricant contained in the reservoir formed by the
recess in the bearing & lifts a portion of the lubricant, to the top of the shaft and
distributes it on each side, the lubricant now works its way through the bearing
& finally escapes at each edge of the bearing into the drippers, the lubricant now
runs back from the drippers to the recess in the bearing by the holes before
mentioned where it is taken up by the peg & used over again; where the bearing
is sufficiently long to render it necessary we form two or more recesses in the
bearing with a peg working in each recess so that the bearing can be lubricated at
two or more points.
"
Where it is preferred to use a washer or disc instead of a peg in connection with
the aforesaid groove or recess formed in the bearing in order to obviate the necessity,
of threading the shaft through the eye of the disc we propose to split the washer
or disc or to cut a segment out of it and spring it on to the shaft, in this case the
washer would require to be made of steel or some other material which would
spring to the required extent, or the washer may be made in two or more portions
which may be connected to each other or to the shaft in any suitable manner.
Where it is inconvenient to have a recess formed in or near the middle of the
bearing and where there is not room for drippers we propose to cut two oblique
grooves one near each edge of the bearing, these grooves alant towards the centre

page_text: of the bearing, in the direction the shaft revolves, when lubricant is supplied to
the bearing it naturally tends to make its way towards each edge, in so doing it
encounters the oblique grooves and as these grooves slant towards the centre of the
bearing they scrape the lubricant off the shaft, and deliver it back to the centre of
the bearing. Where it is inconvenient to remove the shaft from the bearing we
propose to cut two oblique slits one in each edge of the cap and slanting towards
the centre of the bearing in the direction the shaft revolves, in these slits we insert
thin strips of metal or other suitable material so as to rest on and rub against the
shaft, the said strips conducting the lubricant from the outer edge to the centre of
the bearing, thus acting in a similar manner to the oblique grooves.

We, WILLIAM BUTTERWORTH of 182 Wellington St. Bradford Nr Manchester,
Mill Mechanic, HAROLD SHAWCROSS, Woodfield Rochdale, Cotton Spinner &
BENJAMIN BUTTERWORTH of 16 Casson Gate Rochdale Engineer all in the county
of Lancaster do hereby declare the nature of our invention for IMPROVEMENTS IN
THE METHOD OF LUBRICATING THE BEARINGS OF SHAFTS &C and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
At or near the middle of the bottom bearing we form a groove or recess in it,
this recess is made sufficiently large to allow a peg which is fastened to the shaft
to work round in it and also to form a reservoir for oil or other lubricant, on the
sides of the bearing we form or attach drippers to catch the lubricant, as it escapes
from the edges of the bearing these drippers communicate by suitable holes with
the recess in the middle of the bearing, as the shaft revolves the peg which is
fastened to it dips into the lubricant contained in the reservoir formed by the
recess in the middle of the bearing and lifts a portion of the lubricant to the top
of the shaft & distributes it on each side, the lubricant now works its way through
the bearing and finally escapes at each edge of the bearing into the drippers, the
lubricant now runs back from the drippers to the recess in the bearing by the holes
before mentioned where it is taken up by the peg and used over again. Where the
bearing is sufficiently long to render it necessary we form two or more recesses in
the bearing with a peg working in each recess so that the bearing can be lubricated
at two or more points.
Where it is preferred to use a washer or disc instead of a peg in connection
with the aforesaid groove or recess formed in the bearing, in order to obviate the
necessity of threading the shaft through the eye of the disc we propose to split the
washer or disc or to cut a segment out of it & spring it on to the shaft, in this
case the washer would require to be made of steel or some other material which
would spring to the required extent, or the washer may be made in two or more
portions which may be connected to each other or to the shaft in any suitable
manner.
In order that our invention may be readily understood and carried into effect,
reference is made to the accompanying sheet of drawings (the same parts are
marked with the same letter in each Figure). Figures 1 and 2 are sectional
elevations along and across a bearing fitted with our improvement Figures 5 and 4
are sketches showing our method of fixing a disc or washer on a shaft for the
purpose before named, without necessitating the removal of the shaft from its
bearing; a are the steps which form the bearing for the shaft 8, b is a groove or
recess formed in the step for the purpose of forming a reservoir for the oil, and to
allow the peg a to work round in it and dip into the oil, the peg o thus carries the
oil to the top of the shaft s, from here the oil works its way along the shaft a
towards each edge of the bearing, from the edges of which it finally drops into
the drippers & from which it is conveyed again to the reservoir b in the middle of

page_text: the bearing by means of the holes e. The oil is then again taken up by the peg o
and used as before, a constant circulation of oil from the centre to the edges of the
bearing being thus obtained. The peg c instead of being driven into the shaft as
shown, may be screwed in, or be made to clip the shaft as shown in Fig. 3 & sprung
onto it or fastened to it in any convenient manner.
°
Fig. 4 shows a method of fixing a disc or washer on the shaft s to be used if
preferred instead of the peg c for the purpose of dipping into the oil in the recess b
& carrying the oil to the top of the shaft as before mentioned The washer or
disc is shown in two parts f which are fastened together by the screws 9 Fig. 5
shows a method of fixing a disc on the shaft by cutting a segment out of the dise
& then springing it on the shaft.
Having now particularly described our invention and in what manner the same
is to be performed, we declare that what we claim is
1. A Bearing having one or more recesses in it with a peg or pegs working in
them and having drippers formed on each side of the bearing which are in com-
munication with the recess or recesses as and for the purpose herein shown and
described.
2. Where it is preferred to use a disc or washer (instead of the peg we claim
dividing it into two or more parts which are fastened to each other or to the shaft.
3. Cutting a segment out of a washer or disc so as to enable it to be sprung
onto the shaft for the purpose herein described.
