PROVISIONAL SPECIFICATION.
Improvements in Axle-boxes for Rolling Stock.
I, WILLIAM GRIERSON. GLEDHILL of 14, Philadelphia Terrace, The
Knavesmire in the County of York, Engineer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to improvements in the construction of axle-boxes for
rolling stock, and has for object improving the method of lubricating the axle
journals over that heretofore usual for such purpose.
In order to this I construct the grease-box in which is placed the lubricant, as a
separate part so that it can be inserted and withdrawn instantaneously in and from
the body or shell of such axle box, and at the same time this separate grease box is
of such length that the lubricant is applied (practically,) the full length of the
journal instead of near its outer end only as at present obtains in boxes as usually
constructed.
This improved grease box is held in position by a selfacting or other suitable
fastener so as to easily release the same when it is desired to withdraw the
said box.
My further improvement consists in a separate part for attaching to the axle box
proper beneath the journal by means of suitable slides or runners, its office being
to prevent dirt from accumulating on the journal, being provided near the inner
shoulder of the journal with an internal semicircular groove in which is inserted a
packing of any suitable material shaped to fit the periphery of said journal and
held in contact therewith by a spring beneath it thus excluding dirt from passing
into the said loose part and on to the journal, and avoiding the principal cause of
grinding and heating during running. The said separate part and its internal
projection, together with the packing above referred to, can be immediately
removed when desired and in order that the above named projection and packing
may not come in contact with the end collar of the journal during such removal,
it is so arranged that on sliding it a short distance backward on its guiding runners
the whole can drop clear of said guides thus offering the facility for examining and
cleaning, and when replaced in the normal position is secured therein by a suitable
latch or bolt.
At the inner end of the axle box I provide a semicircular projecting shield the
periphery of which is conical, its smallest diameter being next to the box so that
any sand or dirt accumulating thereon may be discharged without being deposited on
the journal.

Improvements in Axle-boxes for Rolling Stock.
I WILLIAM GRIERSON GLEDHILL, of 14, Philadelphia Terrace, The
Knavesmire, in the County of York, Engineer, 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 relates to improvements in the construction of axle-boxes for
rolling stock and has for object the better lubrication of the axle journal and in a
more certain manner than has heretofore been usual.
In order to this I construct the grease-box-in which is placed the lubricant, as a
Prine 8d l

page_text: separate part so that it can be inserted and withdrawn instantaneously in and from
the body or shell of such axle box and at the same time this separately constructed
grease box is of such length that the lubricant is applied (practically) the full
length of the journal instead of near its outer end only as chiefly obtains in axle
boxes as usually constructed, and in order the better to effect this I make the back
or leading in end of said grease-box somewhat lower than the front, and being held
in position by a selfacting or other suitable fastener it can be readily released when
it is desired to withdraw it. My further improvement consists in a separate part
for attaching to the axle-box proper beneath the journal by means of suitable slides
or runners, its object being to prevent dirt or other foreign matter from accumu-
lating on the journal, being provided near the inner shoulder of the journal with an
internal semicircular groove in which is inserted a packing of any suitable material
shaped to fit the periphery of said journal and held in contact therewith by a spring
beneath it thus excluding dirt or foreign matter from passing into the said loose
part and on to the journal and avoiding the principal cause of grinding and heating
during running.
The said separate part and its internal projection together with the packing above
referred to can be immediately removed when desired, and in order that the above
named projection and packing may not come into contact with the end collar of the
journal during such removal, it is so arranged that on sliding it a short distance
backward on its guiding runners the whole can drop clear of said guides thus
offering the facility for examining and cleaning, and when replaced in the normal
position is secured therein by a suitable latch or bolt.
At the inner end of the axle-box I provide a semicircular or segmentally
projecting shield, the periphery of which is conical, its smallest diameter or radius
being next to the box so that any sand or dirt accumulating thereon may be
discharged without being deposited on the journal.

is the body of the axle box. b, is a horizontal partition therein arranged on its
underside to receive the gun-metal bearing c. Above the partition, is inserted the
grease box or drawer d, secured therein by the stirrup or fastener e, which requires
to be raised previous to the withdrawal thereof. f, is a projection or stop to
prevent the drawer from being pulled or accidentally sliding out of its recess without
first raising the front of it. c, 2, 3, are holes through the bottom of the drawer d,
the partition b, and the gun-metal bearing e, for the supply of grease to the journal.
is the separate part for closing the underside of the axle-box. h, h, are the slides
or runners for carrying the part g. i, is a sliding bolt or bar for securing the said
part in its closed position. j, is the internal groove in which is inserted the
packing, and spring, for pressing said packing up to the journal. m, is the
projecting shield at the inner end of the axle-box.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is,
1. In the improved axle-box hereinabove referred to, the construction and
insertion of the grease-box d, in suchwise that it can be instantly removed for
cleaning and filling, and then replaced and secured in position substantially as herein
described and shown.
2. In the improved axle-box herein before referred to the use of a separate part
such as g, for closing the underside of the box, capable of instant removal for
giving access to the journal for its examination and for the removal of waste
lubricant therefrom without raising the vehicle or removing it from a train for

page_text: such purposes, also means for readily replacing and securing the said part g, in its
normal position substantially as described and shown.
3. In the improved axle-box hereinabove referred to, the use at the inner end
thereof of a segmental conical shield such as m, substantially as described and shown
for the purpose specified.
