Improvements in the Manufacture of Axle Boxes for Railway and
other Rolling Stock.
We, WILLIAM DEIGHTON of 13 Hyde Terrace Leeds, Engineer, and BERNAL
BAGSHAWE, of The Cedars Headingley, Leeds in the County of York, Steel
Works Manager, do hereby declare the nature of this invention to be as follows:-
:-
Our present invention relates to certain improvements in the manufacture, or
construction of axle boxes for railway or other rolling stock, & consists in forming
same from rolled sections, and pressed, forged, or cast metal parts, fastened together
by any suitable means such as for instance riveting or welding.
The central or body part we form of one piece of rolled sectional metallic bar
with flanged edges projecting citlier inwardly, or outwardly, varying in form &
thickness with the design of axle-box required to be produced, bent round to the
necessary shape or form and the two abutting edges (forming by preference the
bottom or underside of the axle box) may be welded or riveted together.
The end pieces which we form of stamped, forged, pressed, or cast metal being
provided with projecting edges for the purpose of being riveted or welded to the
central part.
In forming the main or body part of the axle box, we take a bar of metal
preferably of considerable length and pass it through rolls which have previously
been cut to suit the section for the design of axle box required-provision being
made for horn plate guides, spring seat, brass, wedge, & liner guides, &c.-either
collectively or separately. We then cut the sectional bar at right angles, into the
required lengths (each length being sufficient to form the centre part of one axle
box) and afterwards by means of any suitable appliance bend it to a rectangular or
other form of box as required, & weld or rivet the abutting ends.
In some cases it may be more convenient to roll the bars with all the ribs or
projections running uninterruptedly the whole length of the bars, and after they
are cut up into lengths remove the ribs or projections (by any convenient method)
from the parts where they are not required when the bar is bent to the rectangular
form, as for instance the top, bottom, and corners.
It may occur in some designs of axle boxes, that the internal projections for
securing or guiding the brasses, or wedges, may be unsuitable in form to roll upon
the sectional bar forming the outside casing of the central' part of the axle box, and
in such cases separate guide pieces of the required form are secured by riveting, or
other means, between projections rolled on the sectional bar, thus preventing any
horizontal movement.
It may also occur in some designs of axle boxes, that the spring seat may be
unsuitable in form to roll upon the sectional bar. In such cases the spring seat may
be formed by pressing or stamping either before or after the sectional bar has been
bent to the rectangular form, or a separate spring seat may be provided, the
underside of which is formed to suit a recess or opening in the top of the axle box,
& secured thereto by riveting or other means.
If desired the guide pieces for horn plates may be formed of separate pieces of
rolled, cast, or stamped metal, & secured by riveting or other means between
projections rolled upon the sectional bar thus preventing any horizontal movement.

page_text: The dust guard protection plate may be fitted loosely in a rebate rolled on the
sectional bar, forming the centre part of axle box or if desired may be secured
between the end flange and back plate.
In cases where a fixed or loose grease or lubricating box is required, we prefer to
construct same of rolled, stamped, forged, or cast metal having flanges or ribs on
the underside to act as guides for the journal brasses & provided with the necessary
holes for the lubricant to pass through. A suitable projection may be provided on
the end of the grease box for the lid & hinge to be secured to.
Loose blocks may be used if desired between the top of the axle box & bottom of
the grease box to allow the weight on the spring seat to pass direct on to the
brasses, or where a loose spring seat is used the underside of same may pass through
the top of the axle box & sit direct upon the bottom of the lubricating box.

Improvements in the Manufacture of Axle Boxes for Railway and
other Rolling Stock.
We WILLIAM DEIGHTON of 13 Hyde Terrace Leeds in the County of York
Engineer and BERNAL BAGSHAWE of The Cedars Headingley Leeds in the County
of York General Manager, 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 has reference to improvements in the manufacture, or construction
of axle boxes, for railway or other rolling stock, and consists, in forming the central
or body part of one piece of rolled sectional metallic bar, with flanged ends projecting,
bent round to the necessary shape or form, and the two abutting edges (forming by
preference the bottom or underside of the axle box) welded, or riveted together.
The front and back end pieces, which may be of pressed, forged, or cast metal, are
riveted or welded to the central part.
In the accompanying 4 sheets of drawings,
Fig. 1 Sheet 1 is a sectional elevation of an axle box, constructed according to
our improvements, shewing the front and back end plates 25, and 26, previous to
being riveted on to the flanged ends, 4, 4, 4, of the main or body part of the axle
box. 2, 2, are the projections for securing slipper 16, and brass 13. 1, 1, the
projections forming horn plate or axle guard grooves, and 5, projection for taking
the dust guard protection plate.
Fig. 2, is a part sectional half plan of same.
Fig. 3. is a side view of axle box with front and back end plates 27, and 26,
in section. The front end plate 27, being of different design to that shewn in
Fig. 1.
Fig. 4, is a half plan of same.
Fig. 5. is a sectional elevation of axle box complete, suitable for oil lubricant.
The projections 7, 7, form the spring seat, 16, is the slipper, held in position by
the projections 2, 2. 13, is the brass, 15, the journal, 8, dust guard protection
plate, and 11, the axle box lid.
Figs. 6, 7, and 8, are a side elevation, a cross section, and a half plan and half
sectional plan of same.
Fig. 9. is a sectional elevation of axle box complete, fitted with grease chamber 12,
in which the projections 2,2, may act as carriers, or supports for grease chamber, 12,
10, being loose spring. seat.

page_text: Figs. 10 and 11 are half plan and half sectional plan, and cross section of
same.
Figs. 12, and 13, are vertical section, and front views of dust guard protection
plate.
Figs. 14, 15, 16, 17 and 18, shew some different designs of rolled sectional bars,
which may be used for manufacturing our improved axle boxes.
Fig. 19, is a plan of a sectional bar shewing parts of the projections, which may
in some cases not be required removed, as indicated by the dotted lines a, a, e, t
previous to, or after being bent to form the body or main part of axle box.
In manufacturing our improved axle boxes, we take a bar which has been
previously passed through rolls, cut to suit the required section for the design of
axle box to be produced, such as for instance is shewn in Fig. 19. and preferably
after removing those parts of the projections x, x, x, x, which may not be required,
bend it round to form the body or main part of the axle box, and weld the abutting
edges up longitudinally.
A pressed steel front end plate 25, 27, and a pressed steel back plate 26, are
riveted on to the projecting flanged ends 4, 4, 4. The inside projections 2, 2, hold
the slipper 16, and brass 13, securely in position and support the grease chamber 12.
The dust guard protection plate 8, being fitted loosely between the back end
plate 26, and the projection, 5.
In designs of axle boxes where a loose spring seat 10, is required we form a
flanged opening 9, Fig. 9. in the top of the axle box, by pressing, or punching.
The loose spring seat 10, is provided with an extended flange 10, on the
underside, for the purpose of passing through the opening 9, and resting upon the
bottom of the grease chamber 12, or in the case of oil lubricating axle boxes, direct
upon the slipper. Suitable openings 10%, are provided in the flange 10, of the loose
spring seat to allow a free passage for the grease.
The grease chamber 12, when required may be constructed of pressed, forged, or
cast metal, and is provided with longitudinal ribs, 14, on the underside, to receive
the brass 13, in which are suitable openings 16, for the free passage of the lubricant.
A bracket 17, is attached to the end of the body part, or may be secured to front
part 25, 27, for carrying the hinged lid 11.
In some designs of axle boxes it may occur, that the internal projections for
holding the slipper 16, and brass 13, in position, and the external projections for
axle guard grooves, are unsuitable in form, to roll upon the sectional bar forming
the body or main part of the axle box, and in such cases separate guide pieces 18,
Fig. 18, and 19, Fig. 15, of the required form, may be secured between projections 2, 2,
and 6, 6, rolled upon the sectional bar.
It will be obvious that there are other sections of rolled bars, in addition to those
shewn upon Sheet 4 of the accompanying drawings, which may be used, and which
depend upon the design of axle box required to be produced.
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. An axle box constructed from sectional bars, with axle guard grooves, spring
seat, and provision for holding slipper, and brass, (part of the projections removed
therefrom if required) to form the body or main part of the axle box, with separate
front, and back end, plates riveted thereto, substantially as described, with reference
to the accompanying drawings.
2. The hereinbetore described improved axle box, in combination with a separate
grease chamber, substantially as described with reference to the accompanying
drawings.
3. The hereinbefore described improved axle box, in combination with a separate
spring seat, substantially as described with reference to the accompanying
drawings.

page_text: 4. The hereinbefore described improved axle box, in combination with separate
axle guard groove pieces, and separate slipper holding pieces, substantially as
described with reference to the accompanying drawings.
