'
66, Chancery Lane, in the County of Middlesex, Mechanical
Draughtsman, for the Invention of "IMPROVEMENTS IN AXLES BOXES
FOR RAILWAY CARRIAGES."-A communication from abroad by Stous
Scaled the 18th February 1873, and dated the 30th November 1872.
PROVISIONAL SPECIFICATION left by the said Alfred Vincent Newton
at the Office of the Commissioners of Patents, with his Petition,
on the 30th November 1872.
I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Mechanical Draughtsman, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN AXLE
BOXES FOR RAILWAY CARRIAGES," to be as follows:-
This Invention relates to a novel arrangement of axle box for railway
carriages, whereby the journal of the axle to which it is applied may
be lubricated with facility. The box is provided at bottom with a
reservoir for the reception of the lubricant, and an elongated opening is
made in the top of this reservoir to allow of a fibrous material dipping

page_text: into the lubricant and supplying the same
under side of the journal.
The holder of this fibrous conducting material consists of a curved
plate of thin metal provided with a pendant flattened tube for receiving
the fibrous material, which material stands up above the curved plate 5
and is maintained in contact with the journal.
Fitted to the under side of the curved plate are clastic supports or
springs which rest on an adjustable flat plate that is capable of being
raised or lowered.to bring the fibrous material into proper contact with
the journal to be lubricated. An opening is made in this adjustable 1
plate to allow the pendent tube of the curved plate to project through
it. And this tube is surrounded by a similar tube carried by the
adjustable plate.
Pendent from the upper part of the axle box and readily detachable
therefrom are grooved hangers, which are intended to receive the edges
of the flat plate and support it in position in the box. The grooves in
the hangers admit of this plate being shifted nearer to or further from
the journal, and thereby adjusting the fibrous material relatively to the
journal which it is intended to lubricate. This arrangement allows of
an elastic or yielding pressure of the lubricating surface upon the
journal.
The top of the lubricating reservoir is slightly inclined to allow the
superfluous lubricant to drain to one side and filter through a plug of
felt back into the reservoir.
To prevent the motion of the axle box throwing the lubricant
upwards out of the reservoir a dipping tube surrounds the central
opening of the reservoir and reaches to near the bottom of the
reservoir.
The brass on which the journals bear is adjustable from the exterior,
it is squared, and its proportions with respect to the space provided for
containing it are such as to allow of this adjustment.
Lubrication to the brass may be effected through a plugged hole in
the top of the axle box, an opening being made through the brass for
the passage of the oil to its bearing surface.

filed by the said Alfred Vincent Newton in the Great Seal Patent
Office on the 30th May 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Thirtieth day of November, in the
year of our Lord One thousand eight hundred and seventy-two, in the
thirty-sixth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Alfred Vincent Newton, Her special
licence that I, the said Alfred Vincent Newton, my executors, admi- .
nistrators, and assigns, or such others as I, the said Alfred Vincent
Newton, executors, administrators, and assigns, should at any time.
agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for 66
IMPROVEMENTS IN AXLE BOXES FOR RAILWAY CARRIAGES," being
a communication from abroad by Slous Sloot, of Utrecht, in the
Kingdom of Holland, upon the condition (amongst others) that I, the
said Alfred Vincent Newton, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said Alfred Vincent Newton, do hereby'
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, reference being had to the Drawing here-
unto annexed, and to the letters and figures marked thereon (that is
to say)-
This Invention relates to a novel arrangement of railway carriage axle
box which admits of the lubricator being adjusted to the journal of the
axle to which it is applied before closing the axle box.

page_text: In the accompanying Drawing Fig. 1 is a front view of the axle box;
Fig. 2 is an end view of the same, and Fig. 3 is a back view; Fig. 4
is a section of the axle box taken in the line 1, 2, of Fig. 1; and
Fig. 5 is a transverse section of the same taken in the line 3, 4, of
Fig. 2.
The axle box consists of two main parts A and B, the former of
which is fitted with a brass bearing C for the reception of the journal D,
and the latter serves as a reservoir for the oil or other lubricant. The
part B is connected to the part A by screw bolts E which pass through
lugs made to receive them; b is a partition dividing the pendent part B
of the box into two parts, the space below the partition 6 constituting
the reservoir for the lubricant. An elongated opening is made in the
top of this reservoir to allow of a fibrous material or lubricator F
dipping into the lubricant and supplying the same by capillary
attraction to the under side of the journal D.
The holder of this fibrous conducting material consists of a curved
plate of thin metal G, provided with a pendent flattened tube g for
receiving the fibrous material, which material stands up above the
curved plate G and is maintained in contact with the journal.
Fitted to the under side of the curved plate are elastic supports or
springs g, which rest on an adjustable flat plate H that is capable of
being raised or lowered to bring the fibrous material into proper contact
with the journal to be lubricated. An opening is made in this
adjustable plate to allow the pendent tube 9 of the curved plate to
project through it, and this tube is surrounded by a similar tube h
carried by the adjustable plate H.
Pendent from the upper part of the axle box and readily detachable
therefrom are grooved hangers I, which are intended to receive the
edges of the flat plate H and support it in position in the box. The
mode in which the plate H is fitted to the hangers is best shewn
at Fig. 6, which represents the plate and hangers in plan view.
These hangers are secured to the part A of the axle box by means of
pins i, i, Fig. 5. The grooves in the hangers I admit of the plate H
being shifted nearer to or further from the journal to adjust the fibrous
material relatively to the journal which it is intended to lubricate,
which adjustment is effected while the lower part of the box is removed
(as shewn at Fig. 7), and consequently the workman will see whether

page_text: the parts are properly adjusted or not before closing the box. The
above described arrangement moreover allows of an elastic or yielding
pressure of the lubricating surface upon the journal.
The top 6 of the lubricating reservoir is slightly inclined to allow the
superfluous lubricant to drain to one side and filter through a plug of
felt 6 back into the reservoir..
To prevent the motion of the axle box throwing the lubricant
upwards out of the reservoir, a dipping tube 63 surrounds the central
opening of the reservoir and reaches to near the bottom of the
reservoir.
The brass C on which the journal bears may be lubricated through a
plugged hole a in the top part A of the axle box, a passage a¹ being cast
in the box and leading to an opening c made through the brass for the
passage of the oil to its bearing surface.
Having now set forth the nature of the Invention of "Improve-
ments in Axle Boxes for Railway Carriages," as communicated to me
by my foreign correspondent, and explained the manner of carrying
the same into effect, I wish it to be understood that under the above in
part recited Letters Patent I claim, the arrangement of railway carriage
axle box as above described.
In witness whereof, I, the said Alfred Vincent Newton, have here-
unto set my hand and seal, the Thirtieth day of May, in
the year of our Lord One thousand eight hundred and seventy-
three.
