simplify the lubricators, and to ensure the perfect and continuous lubri-
cation of the axle journals. For these purposes a flap pad, sheet, or
web of woollen or other suitable conducting material is suspended direct
from the upper part of the box or bearing at cach side of the journal, in
such manner as to overhang or lap upon the journal at its sides when
hanging free, and to ensure constant contact without undue or useless
pressure, oil or other lubricant being conducted to the bearing parts of
the flap pads, sheets, or webs from a suitable receptacle, by capillary
attraction through the lower ends of the flap pads, sheets, or webs, or by
means of suitable wicks or conductors provided for the purpose.
•
Flanges or fillets may be provided to ensure the flap pads, sheets, or
webs always touching the sides of the journal.
Suspended flap pads, sheets, or webs, as described, may be used singly
instead of in pairs, or may be employed in conjunction with pads bearing
against the under side of the journal.

SPECIFICATION in pursuance of the conditions of the Letters Patent,.
filed by the said Daniel Kinnear Olark in the Great Seal Patent
Office on the 6th February 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, DANIEL
KINNEAR CLARK, of 8, Buckingham Street, in the County of Middlesex,.
Civil Engineer, send greeting.

WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Sixth day of August, in the year
of our Lord One thousand eight hundred and seventy-two, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said Daniel Kinnear Clark, Her special licence
that I, the said Daniel Kinnear Clark, my executors, administrators,
and assigns, or such others as I, the said Daniel Kinnear Clark, my
executors, administrators, and assigns, should at any time agree with,
and no others, from time to time and at all times thereafter 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 Invention for "IMPROVEMENTS IN THE
LUBRICATING ARRANGEMENTS OF AXLE BOXES FOR RAILWAY ROLLING STOCK," a

page_text: communication to me from abroad by James Sidebotham, of Cairo, Egypt,
upon the condition (amongst others) that I, the said Daniel Kinnear Olark,
my executors or administrators, by an instrument in writing under, 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 Daniel Kinnear Clark, do hereby
declaro 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 thereof, reference being had to the Drawings
hereunto annexed, that is to say :—
This Invention has for its object improvements in the lubricating
arrangements of axle boxes for railway.rolling stock, and is designed to
simplify the lubricators, and to ensure the perfect and continuous lubri-
cation of the axle journals. For these purposes a flap, sheet, or web of
woollen or other suitable conducting material is suspended directly from,
or attached to, the upper part of the box, or to the bearing at each side
of the journal, in such a manner as to overhang or lap upon the journal
at its sides when hanging free, and to be constantly in contact with the
journal without undue or useless pressure, oil or other -lubricant being
conducted to the bearing parts of the flaps, sheets, or webs from a suit-
able receptacle, by capillary action thro' the lower edges or ends of the
flaps, sheets, or webs, or with the aid of suitable wicks or conductors
attached to the flaps.
Flanges or fillets may be provided to steady the flaps, sheets, or webs,
and to ensure that they shall always be in contact with the sides of the.
journal; or the flaps may be weighted for that purpose by attaching to
them pieces of lead or other heavy substance.
Suspended flaps, sheets, or webs, as described; may be applied to only
one side of an axle journal, instead of to both sides.
Pads bearing against the under side of the journal may be employed in
conjunction with suspended flaps.
In order that the said Invention may be fully understood I shall
now proceed more particularly to describe the same, and for that purpose
shall refer to the Figures on the annexed Sheet of Drawings. -

page_text: Fig. 1 is a longitudinal section, and Fig. 2 is a transverse section of an
axle box for a railway carriage or waggon.
A is the journal of the axle; B, B, is the upper part of the axle box ;
and C, C, is the lower part; D is the bearing resting on the journal;
E, E, are the flaps, sheets, or webs of felt or other suitable material for 5
Jubricating the journal, one being suspended on each side of the journal
and attached to the bearing by the pins F, F, or they may be attached
to the upper part of the box. The lower edges or cnd of the flaps or
webs hang down into the reservoir of oil in the lower part of the axle
box to receive and convey the oil to the journal by capillary action. The 1
flaps or webs here shown are made each in one piece, doubled on itself,
and stitched together, but they may be in a single sheet.
Ribs a, a, may be cast on the sides of the axle box to steady the flaps
or webs, and keep them in place.
For the same object the flaps may be weighted by pieces of lead or 1
other weighty substance attached to them as shown, for example, in dot
lines at b, b, Figs. 1 & 2.
A lubricating pad H may be applied below the journal in conjunction
with the side flaps, and to continue the lubricating action in case of
accident to the side flaps. It is supported on springs from the bottom a
of the axle box. A shield or diaphragm I, I, coated with felt on both
sides is applied at the back of the axle box to prevent oil escaping, or
dust entering the box. A supplementary grease chamber K, K, is here
shown, but it is only proposed as an auxiliary to the oil lubrication, and
to hold a supply of grease for the purpose of being kept in reserve for
use in case of accident to the lubricating flaps, or to the lower part of
the axle box, the grease being prevented from descending on the journal
so long as oil lubrication is in action, by a layer of felt or other material L
laid on the floor of the greaso chamber, so as to cover the grease
channels M, M, or the grease channels may be stopped up by plugs.
Oil may be introduced into the axlo box by the opening N, shown in
dot lining, which is closed with a plug.
Another variety of axle box, without any grease chamber, is shown in
Fig. 3. The flaps are suspended from the upper part of the axle box.
The lettering refers to parts corresponding to those having the same
lettering in Figs. 1 & 2. The weights b, b, shown in dot lining, are
attached to the lower ends of the webs.

page_text: A receptacle for oil may be so constructed as to separate the spent
oil from the fresh oil.
Having now described & particularly ascertained the nature of the
said Invention, and the manner in which the same is or may be used
or carried out, I would observe in conclusion that what I consider to be
novel and therefore claim as my Invention is, the application of flaps,
sheets, or webs of felt, woollen, or other suitable material in the axle
boxes of railway rolling stock, suspended directly from or attached to
the upper part of the axle boxes, or to their bearings, so as to overhang
or bear upon the sides of the axle journals for the lubrication thereof, by
supplying oil or other lubricant, which is conducted to the parts of the
flaps, sheets, or webs in contact with the journals from suitable recep-
tacles, by capillary action thro' the lower ends of the flaps, sheets, or
webs, substantially as described.
In witness whereof, I, the said Daniel Kinnear Clark, have here-
unto set my hand & seal, this Sixth day of February, One
thousand eight hundred and seventy-three.
