PROVISIONAL SPECIFICATION.
Improvements in Bearings.
JOHN WILLIAM SHEARD, Wood Turner 66 High Street Blackpool and JOHN
DONE, Builders Clerk 4 Layton Road Blackpool in the County of Lancashire do
hereby declare the nature of this invention to be as follows:-
The improvement consists of segmental pieces of iron, steel, brass gunmetal,
bronze or any other metal or composition of metals made up into the form or forms
of bearings for shafting, eccentrics, crank shafts and loose pullies for all
descriptions of machinery, engines, and vehicles.
They are made either straight or spiral, and are either solid or perforated.
And we claim that this bearing reduces friction, wear & tear and that it
Baves oil.
The improvement differs from an ordinary bearing with brasses in that the
ordinary brasses are done away with, and the segmental pieces aforesaid are placed
round the shaft or in the bush of the pulley or wheel & the like making up a true
circle of them, and then in the case of a bearing a cast iron or other metal bush,
(preferably in two halves somewhat similar to an ordinary bearing and the like)
having a raised projection or rim on the outside edge, is placed over the segments
thus keeping them in position, and in the case of a loose pully or the like the
segmental pieces aforesaid form the bush and these are kept in position by an
ordinary collar. On the shaft or loose pulley & the like revolving, the segmental
pieces will revolve with it but at a much slower speed.

JOHN WILLIAM SHEARD Wood Turner of 66 High Street and JOHN DONE
Builders Clerk of 4 Layton Road both of Blackpool 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 :-
This invention relates to bearings or journal-linings for wheels, cylindrical drums
journal boxes, pullies and the like, and consists of segmental pieces of iron, steel,
brass, gun-metal, bronze or any other metal or composition of metals, made up into
the required form or forms of bearings for shafting eccentrics, crank shafts and
loose pullies for all descriptions of machines, engines and vehicles as hereinafter
described.
The invention is fully described in the following Specification and of which the
accompanying drawings form a part in which
Fig. 1 is a longitudinal section of a portion of a bearing and the like provided
with our improved packing or journal-lining and
Fig. 2 is a transverse section of a bearing and the like similarly provided.
Our improvement differs from the ordinary bearing consisting of brasses or
similar devices, in that the brasses are done away with, and the segmental pieces

and the like the segments forming a circle, one or more straps being employed,
where required to keep the segments in position when filling & also to convey oil
from the lubricators to the bearing surfaces.
Referring to the drawings A designates the body of a wheel, pully, cylindrical
drum or the like and B our improved packings or bearings and C longitudinal
recesses for oil or other lubricants employed or formed when or where necessary
and preferably on both the inner and outer sides of the bearings or journal-linings.
The annular collar or projection D Fig. 1 is designed to keep the segments from
working out or moving longitudinally, the annular collar shown at E Fig. 1 is
designed.for the same purpose as D but so as to allow the bearings or linings to
extend the full width of the bush and the like and can be used when or where
required, and straps or bands F Fig. 1 are also employed to keep the segments in
position when filling & to carry oil to the bearing surfaces.
The longitudinal recess or recesses C are for oil or other lubricants and small
openings or perforations G Fig. 1 in any required form or quantity are for con-
veying oil and the like from the outer to the inner surfaces of the bearings or
journal-linings, it being understood that these recesses and openings are in com-
munication with the oil-passages, not shown, in the usual mauner in the body of the
pedestal, wheel, pulley, cylindrical drum and the like.
Referring to Fig. 2 H designates a space or clearance necessary for the free
action of the segments, thus the segments act independently of the pulley, bearing
or the like and they cannot bind each other, which they would be liable to do if
there was no clearance.
In the case of an ordinary bearing the inside of the pedestal, cylindrical drum
wheel or the like can be bored out and forced to provide a recess for the segments,
or the segments can be fitted to any style of bearing and the raised annular
projections or shoulders D keep the segments in position, and in the case of a loose
pulley & the like the segmental pieces form the bush or bearing and are held in
place by an ordinary collar, and when the shaft or loose pulley revolves the
friction will cause the segmental pieces to revolve also but at a much slower
speed.
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
1. A packing, or bearing, or journal-lining for pulleys wheels, cylindrical drums
shafting and the like consisting of segmental strips of brass iron, gun-metal or
other metals and the like substantially as shown and described.
2. A packing, or bearing for pulleys, wheels cylindrical drums, shafting & the
liko consisting of segmental strips of brass, iron, gun-metal or other metals and the
like, and annular strips or bands for holding the segments in place substantially as
shown and described.
3. A packing or bearing for pulleys wheels cylindrical druins, shafting and the
like consisting of segmental strips of brass, iron gun-metal or other metal and
the like provided with longitudinal recesses & perforations or openings for oil or
other lubricants substantially as shown and described.
4. A packing or bearing for pulleys wheels cylindrical druins, shafting & the like
consisting of segmental strips of brass, iron, gun metal or other metals and the
like provided with longitudinal recesses & perforations or openings for oil or other
lubricants and annular strips or bands for holding the segments in position
substantially as shown and described.
