PROVISIONAL SPECIFICATION.
Improvements in Axle Boxes and Bearings for Railway Carriages
and Wagons.
PETER ELLIS 28 Sale Street Derby in the County of Derbyshire Engineer, do hereby
declare the nature of this invention to be as follows :-
1st. My invention consists of an improved form of Axle box in which the upper
inside portion of it is so arranged as to receive a loose chamber which holds a large
supply of lubricating grease or oil.
This chamber is in the form of a drawer and can be pushed in or drawn out as
required. It is secured in its place or working position by two wrought iron bolts
and nuts.
The Axle box is so formed internally as to receive the drawer or grease chamber
between the top of the box where the bearing spring rests upon, and the top or back
part of the gun metal bearing, thus taking the weight of the load between the two.
The bottom surface of the drawer and the top surface of the gun metal bearing are
flat, thus requiring no labour to make them fit together properly.
2nd. The inside of the axle box is so formed that the gun metal bearing is put in
from the top opening, and drops into a recess at each side which keeps the bearing in
its right place. The drawer or grease chamber is then put in over or upon the top
of the gun metal bearing which effectually prevents it getting out of its place or
turning when in work.
The advantages and utility of this arrangement of axle box and bearing are, that
the latter requires no labour in fitting it into the axle box, that the bearing cannot
turn round or get out of place, that it can and will accomodate itself to the right
position on the journal of the axle, that the brass bearing can be refitted to the
journal or a new brass bearing can be fitted properly to the journal and put in without
lifting the vehicle or taking the axle box or the wheels from under it.
If a piece of iron, or wood is placed between the axleguard stay and the under-
side of the axle box and a screw jack put under the corner of the vehicle to take the
weight of the load off the journal, the drawer B can be taken out, also the brass
bearing and journal examined and put right when necessary.
A is the main casting of the axlebox, B the drawer or grease chamber, C the wrought
iron bolts, D the brass bearing, E are recesses into which the brass bearing is placed,
F is a little clearance or liberty between the brass bearing and the axlebox which
allows the brass to adjust itself to the right position on the journal. The drawer B has
holes g opposite the holes g in the brass bearing D) to allow the grease or oil to go
down to the journal.
Having now described the nature, arrangement and purpose of my said invention
and in what manner the same is to be performed I declare that what I claim is an
improvement in Axle boxes and Bearings for Railway Carriages and Wagons sub-
stantially as set forth in the foregoing description thereof and the accompanying
drawings.

Improvements in Axle Boxes and Bearings for Railway Carriages
and Wagons.
PETER ELLIS 28 Sale Street Derby in the County of Derby Engineer, 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 :-
1st. My invention consists of an improved form of Axle Box in which the upper

page_text: inside portion of it is so arranged as to receive a loose chamber which bolds a large
supply of lubricating grease or oil.
This chamber is in the form of a drawer and can be pushed in or drawn out
as required. It is secured in its place or working position by two wrought iron
bolts and nuts.
The Axle box is so formed internally as to receive the drawer or grease chamber
between the top of the box where the bearing spring rests upon, and the top or
back part of the gun metal bearing, thus taking the weight of the load between
the two.
The bottom surface of the drawer and the top surface of the gun metal bearing
are flat, thus requiring, no labour to make them fit together properly.
2nd. The inside of the Axle Box is so formed that the gun metal bearing is put in
from the top opening, and drops into a recess at each side which keeps the bearing
in its right place. The drawer or grease chamber is then put in over or upon
the top of the gun metal bearing which effectually prevents it getting out of its
place or turning when in work.
The advantages and utility of this arrangement of Axle box and bearing are, that
the latter requires no labour in fitting it into the Axle box, that the bearing cannot
turn round or get out of place, that it can and will accomodate itself to the right
position on the journal of the Axle, that the brass bearing can be refitted to the
journal or a new brass bearing can be fitted properly to the journal and put in without
lifting the vehicle or taking the Axle box or the wheels from under it.
If a piece of iron or wood is placed between the Axleguard stay and the under-
side of the Axle box, and a screw-jack put under the corner of the vehicle to take
the weight of the load off the journal, the drawer or grease chamber can be taken
out, also the brass bearing and journal examined and put right when necessary.
A is the main casting of the Axle box, B the drawer or grease chamber, C the wrought
iron bolts, D the brass bearing, E are the recesses into which the brass bearing is
placed, F is a little clearance or liberty between the brass bearing and the Axle box
which allows the brass to adjust itself to the right position on the journal. The
drawer B has holes g opposite the holes g in the brass bearing D to allow the grease
or oil to go down to the journal.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is performed, I declare that what I
claim is
An improvement in Axle boxes and Bearings for Railway Carriages and Wagons
and in the combined arrangements of parts substantially as set forth in the foregoing
description thereof and the drawings left with the provisional specification.
