PROVISIONAL STEIFICATION.
Improvements in Railway Carriage or Wagon Axle Bearings.
I ANTONIO RICHARDSON Wilford House Garden Road, Mansfield in the
County of Nottingham Brass Founder do hereby declare the nature of this
invention to be as follows:-
My invention relates to the materials used, the means employed, and the manner
of carrying out the same.
In consequence of the heavy wear on the ends of railway carriage. and wagon
bearings, owing to the oscillation of the carriages and other causes, the bearings
have in the majority of cases to be thrown out as unfit for further service because of
such wear to the ends and replaced with new ones entirely, whilst the thickness of
the bearing has not been appreciably worn, thereby causing very heavy renewal
charges.
The object of this invention is to provide a means for renewing such worn parts
only, and for the renewal of such parts when worn so as to make such bearings
(which would otherwise be useless) fit for further service and which may be
repeated from time to time as required until the bearing itself is quite worn out, and
seeing that frequently under present conditions, bearings are thrown out with less
than 2% reduction from the original weight it will be apparent that by the use of
my invention there must be an immense saving to railway companies and owners of
wagons.
The accompanying drawings will explain my invention.

which is now made in various shapes and sizes but all answering the same
purpose.
Fig. 2 is an end view.
The original bearing which as now is cast in gunmetal bronze or other suitable
material has the ends cored out or left with a cavity, the form or shape of the inside.
of such cavity I adopt by preference is as shown by dog tooth lines A & A'
Figs. 1 & 2 such cavity being enlarged or undercut inwards as shown at B & B¹
Figs. 1 & 2 or the roughening inside may be done in a variety of other shapes
baving the same aim. The object of such roughening and enlargement or
undercutting being to form a grip and thereby effectually secure a filling of
antifriction or other suitable metal hereafter described. Or such cavity may be
only partially roughened and partly plain as shown by lines C & C¹ Figs. 1 & 2,
or wholly plain.

I do not confine myself to the particular shapes shown and described.
The bearings having been first made with a cavity as described, an antifriction
or other suitable metal which will melt at a lower temperature than that of the
bearing itself, is run into such cavities to the form and shape required either in a
finished state or to be finished by machining. And when the ends of the bearings
so formed become worn by use, the said antifriction or other suitable metal is melted
out of such cavities and the renewal of such ends carried out in the same manner as
already described, this being done without the slightest damage to the original
bearing.
Fig. 3. represents another mode of carrying out my invention the said cavity
being simply enlarged or undercut and quite plain as shown by lines D & D₁
Figs. 3 & 4, the portions for renewal being of a similar metal to the bearing itself
and driven tightly into the cavity, the same being held firmly and permanently in
position by a screw or bolt E & E¹ Figs. 3 & 4 passing through the back of the

page_text: bearing into the said renewal piece or pieces, such renewal piece or pieces when
worn being driven out and replaced with a perfect one.

It must be understood that I do not confine myself to the forms or shapes shown
in the drawings, any other forms or shapes may be used to secure the same results
and having a like object, which is evident may take a variety of forms so long as
the same object is gained.

COMPLETE SPECIFICATION.
Improvements in Railway Carriage or Wagon Axle Bearings.
ANTONIO RICHARDSON Wilford House Garden Road Mansfield in the County
of Nottingham Brass Founder. I 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:-
My invention relates to the materials used, the means employed and the manner
of carrying out the same.
In consequence of the heavy wear on the ends of railway carriage and wagon and
other bearings owing to the oscillation of the carriages and other causes, the
bearings have in the majority of cases to be thrown out as unfit for further service
because of such wear to the ends and replaced with new ones entirely, whilst the
thickness of the bearing has not been appreciably worn thereby causing very heavy
renewal charges.
The object of this invention is to provide a means for renewing auch worn parts
only and for the renewal of such parts when worn, so as to make such bearings
(which would otherwise be useless) fit for further service and, which may be
repeated from time to time as required until the bearing itself is quite worn out and
seeing that frequently under present conditions, bearings are thrown out with less.
than 2 per cent. reduction from the original weight, it will be apparent, that by the
use of my invention there must be an immense saving to railway companies and
owners of wagons.
The drawings as left with my Provisional Specification will explain my
invention.
Fig. 1 is a plan of face or working side of a railway carriage or wagon bearing
which is now made in various shapes and sizes, but all answering the same
purpose.
Fig. 2 is an end view.
Such illustrations will serve to explain the application of my invention to other
bearings.
The original or greater portion of the bearing is cast in gunmetal, bronze or other
suitable material, having the ends recessed or cored out or left with a cavity.
The form or shape of the inside of such cavity I adopt by preference, is as shown
by the dog toothed lines A and A' Figs. 1 & 2 such cavity being enlarged or
undercut inwards as shown at B & B¹ Figs. 1 & 2 or the roughening inside may be
done in a variety of other shapes having the same aim or producing the same
results. The object of such roughening and enlargement or undercutting, being to
form a grip or hold and thereby effectually securing a filling of antifriction or other
suitable metal hereafter described. Or such cavity may be only partially
roughened and partly plain as shown by lines C & C Figs. 1 & 2 or wholly plain
or alternate recesses or cavities and ribs of the original metal may be formed
or cast in the ends of the bearings and insets of antifriction or other metal, run,
driven or otherwise fitted in.
I do not confine myself to the particular shapes shown or described.

page_text: The bearings having been first made with a cavity as described, an antifriction or
other suitable metal, which will melt at a lower temperature, than that of the
bearing itself, is run into such cavities to the form and shape required, either in a
finished state or to be subsequently finished by machining and when the ends of the
bearings so formed, become worn by use, the said antifriction or other suitable metal is
melted out of such cavities and the renewal of such ends carried out by repeating
the process in the manner already described, this being done without the slightest
damage to the original bearing.
Fig. 3 represents another mode of carrying out my invention. The said cavity
being enlarged, dovetailed or undercut and may be quite plain in the joining parts
as shown by lines D & D' Figs. 3 & 4.
The renewal ends or insets being of a similar metal to the bearing or euch
renewal ends may extend over the whole surface of the ends of the bearing itself
and driven tightly into the cavity, the same being held firmly and permanently in
position by one or more screws bolts or rivets E & E¹ Figs. 3 & 4. passing through
the back or otherwise of the bearing into the said renewal end piece or pieces or
insets, such renewal piece or pieces or insets when worn being driven out and
replaced with perfect ones.
Fig. 4 is an end view of Fig. 3.
It must be understood that I do not confine myself to the materials named
herein or the forms or shapes shown in the drawings, any other materials or forms
or shapes may be used to secure the same result and having a like object which is
evident may take a variety of forms so long as the same object is gained.
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
1. The provision and application of a means for the renewal of the worn parts of the
ends of railway wagon and other bearings and thereby securing for further service
what would otherwise be thrown out as scrap, substantially as described and set
forth.
Dated this 4th day of August 1894.
