I WILLIAM DANIEL, Secretary of the Lartigue Railway Company (Limited) of 55
and 56 Chancery Lane, in the County of Middlesex, do hereby declare the nature of
this Invention to be as follows:-
This Invention relates to improvements in the lubrication of axle-boxes, shafts, and
other frictional surfaces of machinery.
The essential feature of the Invention consists in the employment in the oil-box, of
transferring rollers, which float in the oil and are rotated by contact with the journal
or other part to be lubricated, and transfer the oil thereto.
They are preferably of cylindrical form and are pressed by their own buoyancy
constantly up against the journal.
In the case of an axle-box, space is provided above the bearing for a solid lubricant
to be melted by the heat of the journal, in the event of the oil running short.

Improvements in Lubricators for Axle-boxes and Bearings.
I WILLIAM DANIEL Secretary of the Lartigue Railway Company (Limited) of 55
and 56 Chancery Lane in the County of Middlesex do hereby declare the nature of
this Invention (a communication to me from abroad by Charles François Marie
Thérèso Lartigue of Olieste Spain Engineer) and in what manner the same is to be
performed to be particularly described and ascertained in and by the following a
statement:
This Invention relates to improvements in the lubrication of axle journals and
shafts, in cases where the bearing is above the axle &c to be lubricated.
The essential feature of the Invention consists in the employment in the oil box of
transferring rollers which float in the oil and are rotated by frictional contact with the 1
axle journal to be lubricated and transfer the oil thereto. They are preferably of
cylindrical form, and are by their own buoyancy caused to press constantly up against
the journal.
Reference is to be had to the accompanying drawings forming part of this specifi-
cation wherein figure 1 represents a front clevation of an axle box figure 2 represents 1
a vertical cross section of the same at right angles to the axle journal, figure 3
represents a vertical longitudinal section of the same in the plane of the journal which
is shewn as withdrawn from the box, figure 4 represents a plan view of the same, with
the top cover removed and figure 5 shews the top cover separately. The same letters
of reference indicate the same parts in all the figures.
a is an axle box which would of course be adapted by its form, dimensions, and
arrangements to suit the piece of mechanism to be lubricated. It is closed at top by
a cap secured by bolts c or in any other suitable manner. It contains a bearing
brass d adapted to rest on the journal e of the shaft or axle, this brass being curved
on its under surface to conform to the circumference of the journal and of such form
on the upper surface as to leave spaces for the reception of a solid lubricant to be
melted by the heating of the bearing should the oil run short, holes g being formed
through the bearing to admit the melted lubricant to the frictional surfaces. The
brass is formed with end flanges and a central rib on the upper surface which
are flush with the top of the grease box and bear against the cap b. The lower edges
of the semicircular part of the brass are turned outwards, as at to meet the walls of
the oil box as shewn in figure 2, and are notched to receive vertical ribs a³ formed on
the sides of the box. In the lower part of the box are contained two floats h, of
cylindrical form by preference, of a length approximately corresponding to the length
of the journal to be lubricated. They are made of cork or other suitable material and a
are of such diameter and the oil is at such a height in the box that they will always
be caused by their own buoyancy to press against the lower side of the journal in the
manner shewn in figure 2, so as by their rotation in the oil caused by frictional
contact with the journal to transfer thereto the oil necessary for the lubrication of the
journal and bearing.

page_text: The construction of the lubricator above described would of course be modified
according to the form of top bearing, to which it is applied as will be readily
understood.
Having now particularly described and ascertained the nature of the said Invention
and in what manner the same is to be performed I declare that what I claim is :-
In an axle-box or other form of bearing placed above the journal to be lubricated
the employment of transferring rollers floating in oil and pressed by their own
buoyancy into rolling contact with the surface of the journal to be lubricated, as
described.
