Complete Specification Accepted, 30th Mar., 1889
We, JOHN WARD WILLIAMS and HENRY WARD WILLIAMS both of Abertillery
Foundry, Abertillery, in the county of Monmouth, engineers and ironfounders, do
hereby declare the nature of this invention to be as follows :-
-
This invention which relates to axle boxes for railway and tramway vehicles consists
in an improved arrangement for the better and more economical lubrication of the
journals of the axles of the wheels of such vehicles.
Below the journal and in contact therewith is a roller of india rubber or other suit-
able material free to rotate on a spindle fixed towards its ends to a bracket suspended
by bolts from the upper part of the axle box which is made separate from and is
bolted to the lower part.
By means of springs encircling the bolts and bearing at one end against nuts
screwed upon the lower ends of the bolts, the roller aforesaid is kept constantly in
contact with the journal and rotates therewith.
The lubricant used is oil, which is poured into the box through an aperture at the front
governed by a door or slide. The lubricating roller is partially immersed in the oil
and as the roller rotates with the journal it lubricates the latter and its bearing in
proportion to the rate of rotation. The lubricating roller is preferably composed of a
band of india rubber or other suitable material embracing a metallic boss which is
loose upon the spindle aforesaid. As the lubrication of the bearing takes place when
the journal rotates, grinding action on the bearing is obviated. There is, moreover,
less waste of the lubricant.
The bolts by which the bracket carrying the lubricating roller is suspended are
inseried from below into the upper part of the box. They are provided with T heads
which, after having been received in a recess, are turned so as to bring the heads
crosswise on the seat. The nuts at the lower ends of the bolts are received between
guides by which they are prevented from turning.
Dated this 14th day of May 1888.

page_text: We, JOHN WARD WILLIAMS and HENRY WARD WILLIAMS both of Abertillery
Foundry, Abertillery in the county of Monmouth, engineers and ironfounders, 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, which relates to axle boxes for railway and tramway vehicles,
consists in an improved arrangement for the better and more economical lubrication
of the journals of the axles of the wheels of such vehicles.
Below the journal and in contact therewith is a roller of india-rubber, or other
suitable material, free to rotate on a spindle fixed towards its ends to a bracket
suspended by bolts from the upper part of the axle box which is made separate
from and is bolted to the lower part.
By means of springs encircling the bolts and bearing at one end against nuts
screwed upon the lower ends of the bolts, the roller aforesaid is kept constantly in
contact with the journal and rotates therewith.
The lubricant used is oil, which is poured into the box through an aperture at
the front governed by a door or slide.
The lubricating roller is partially immersed in the oil and as the roller rotates
with the journal it lubricates the latter and its bearing in proportion to the rate of
rotation.
Referring to the accompanying drawings, Figs. 1 & 2 represent different sections
of an axle box constructed and fitted with a lubricating roller in accordance with
one method of carrying our invention into practical effect.
Below the journal a and in contact therewith is a roller composed of a band b of
india-rubber or other suitable material embracing a metal boss c which is loose upon
the spindle d and is free to rotate thereon.
h
The spindle d is secured at each end by pins e, or otherwise, to a bracket f
suspended by bolts g from the upper part of the axle box which is made separate
from and is bolted to the lower part. By the spring encircling the lower ends of
the bolts and bearing at one end against the bracket f and at the other against
the nuts g screwed upon the bolts the lubricating roller, which is partially immersed
in oil contained in the lower part of the box, is maintained constantly in contact with
the journal a from which it derives a rotatory motion. The journal a and the
bearing i are lubricated by the roller as it rotates.
The lubricant is supplied to the axle box through the aperture k, Fig. 2, which is
governed by a door or cover.
As lubrication of the bearing takes place when the journal rotates, the grinding
action, hitherto obtaining, produced on the bearing is obviated and there is less waste
of the lubricant.

page_text: In the arrangement illustrated at Figs. 1 & 2 the bolts gare provided with T-heads g².
The bolts are inserted from below and, when in place, the T heads are received in
circular recesses formed therefor in the upper part of the box. The bolts are then
turned so as to bring the heads cross-wise in the recesses. Fig. 3 illustrates in section
a modified arrangement under which the lubricating roller is situated towards the
outer end of the journal a.
The roller may, instead of rotating about a horizontal axis, be arranged to rotate
about an axis at an angle to that of the journal a of the axle.
The bolts g by which the bracket is suspended may, instead of being T-headed
and inserted from below, as herein before described with reference to Figs. 1 & 2; be
furnished with ordinary square or approximately square heads, as shewn at Fig. 3,
and be inserted in their places from above.
Having now particularly described and ascertained the nature of this inven
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. In an axle box for railway and tramway vehicles, the use of a lubricating roller
such as embraced by a band such as c of india-rubber or other like or suitable
material, in contact with the periphery of the journal and rotating therewith, sub-
stantially as described.
2. The bracket carrying the lubricating roller, and suspended from the upper
part of the axle box by bolts such as g fitted with spring h or their equivalent,
substantially as herein before described.
3. The combination of parts constituting the improved axle box, constructed,
arranged and operating substantially as herein before described.
