Improvements relating to the Lubrication of Wheel Axle Bearings
and Wheels.
We, THOMAS HEDGES DEAKIN, J.P., Colliery Proprietor, FREDERICK SAMUEL
GEACH, Engineer, and DAVID POWELL, Cashier, all of Varteg, in the County of
Monmouth, do hereby declare the nature of this invention to be as follows:-
Our invention relates to improvements in the means for the lubrication of axle
bearings of colliery trucks, tramcars, trams, tubs, corves and other vehicles in
which the axle rotates within the carrying bearings of the vehicle and where the
wheel is rigidly secured to the axle, and is also applicable where the wheel rotates
upon the axle."
Our invention has for its object to effect a continuous and efficient lubrication
of the axle bearings.
In carrying our invention into effect we provide the wheels which are to be
secured to the axle with lubricating chambers in one or more of the arms or spokes
as described in the specification of patent granted to us No. 625 of 1896. Pro-
jecting into this chamber we provide a communicating tube secured to the boss of
the wheel which communicates with the periphery of the axle, an annular chamber
being provided about the periphery of the axle so that the oil or lubricant which
on the rotation of the wheel is caused to pass through the communicating tube,
passes into this surrounding annular chamber whence it may pass by transverse
or radial passages into an axial channel or bore provided in the axle or spindle
and into communication by other transverse or radial passages to the bearing
surface of the bearing or carrying bracket of the vehicle.
By providing the axle thus with axial and transverse communicating passages
the lubricant which on the rotation of the wheel is caused to descend to the ex-
tremity of the arm of spoke chamber next the periphery, on further rotation is
caused to pass, to a certain small amount, down the communicating tube, so that
the lubricant is conveyed between the bearing surfaces of the axle and carrying
bracket and so a constant and effective lubrication is effected on the motion of
the vehicle.
We provide suitable apertures upon the lubricating chamber or chambers capable
of being closed with screwed plugs so that the lubricant may be introduced into
the chambers.
We do not limit ourselves to the use of a communicating tube from the chamber
or chambers for conveying the lubricant to the axle bearings, as other means may
be employed such as that described in the specification above referred to; but we
may use such a tube for conveying lubricant to the wheel bearing surface, when
applying wheels to rotate upon the extremities of the axle, without departing from
our invention.
It is obvious also that we may employ but one wheel having lubricating chambers
within its arms, in which case we provide an axial passage or bore in the axle,

Improvements relating to the Lubrication of Wheel Axle Bearings
and Wheels.
We, THOMAS HEDGES DEAKIN, J.P., Colliery Proprietor, FREDERICK SAMUEL
GEACH, Engineer, and DAVID POWELL, Cashier, all of Varteg, in the County of
Monmouth, 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:--
Our invention relates to improvements in the means for the lubrication of axle
bearings of colliery trucks, tramcars, trams, tubs, corves and other vehicles in
which the axle rotates within the carrying bearings of the vehicle and where the
wheel is rigidly secured to the axle, and is also applicable where the wheel rotates
upon the axle.
Our invention has for its object to effect a continuous and efficient lubrication
of the axle bearings, and a saving in the quantity of lubricant used.
Our invention is illustrated in the accompanying drawings in which
Figure 1 is a part sectional end elevation of an axle and wheels mounted thereon.
Figure 2 is a part sectional front elevation on the line ab Figure 1 while
Figure 3 is a front elevation corresponding thereto, and
Figure 4 is a side elevation of the carrying bracket and
Figure 5 is a detail section of oil filling valve.
In carrying our invention into effect according to the accompanying drawings
we provide the wheels A which are to be secured to the axle B with lubricating
chambers C in one or more of the arms or spokes as described in the specification
of patent granted to us No. 625 of 1896. Projecting into this chamber we pro-
vide a communicating tube D secured to the boss of the wheel A which communi-
cates with the periphery of the axle B, an annular chamber E being provided
about the periphery of the axle B so that the oil or lubricant which on the rotation
of the wheel A is caused to pass through the communicating tube D, passes into
this surrounding annular chamber E, whence it may pass by a transverse or radial
passage or passages F into an axial channel or bore G provided in the axle or
spindle B and into communication by other transverse or radial passages H to the
bearing surface of the bearing or carrying bracket I of the vehicle.
By providing the axle thus with axial and transverse communicating
passages F, G, H, the lubricant which on the rotation of the wheel A is caused to
descend to the extremity of the arm or spoke chamber next the periphery, on
further rotation is caused to pass, to a certain small amount, down the com-
municating tube D, so that the lubricant is conveyed between the bearing surfaces
of the axle and carrying bracket and so a constant and effective lubrication is
attained on the motion of the vehicle.
We provide suitable apertures upon the lubricating chamber or chambers capable
of being closed with "screwed plugs so that the lubricant may be introduced into
the chambers.

page_text: We prefer however to employ an oil filling valve J which is maintained upon its
seat by means of a spring K, the whole being provided within a casing L screwed
into side of the lubricating chambers.
We do not limit ourselves to the use of a communicating tube D from the
chamber or chambers for conveying the lubricant to the axle bearings, as other
means may be employed such as that described in the specification above referred
to; but we may use such a tube for conveying lubricant to the wheel bearing sur-
face, when applying wheels to rotate upon the extremities of the axle, without
departing from our invention.
It is obvious also that we may employ but one wheel having lubricating chambers
within its arms, in which case we provide an axial passage or bore in the axle,
so that the lubricant may be conveyed to both axle bearings, and the wheel upon
the opposite extremity of the axle need not of course carry the lubricant.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what we
claim is:-
1. In means for the lubrication of the bearing surfaces of wheels and axles, the
use of a communicating tube from the wheel chamber containing the lubricant
substantially as and for the purpose hereinbefore described.
2. Means for the lubrication of the bearing surfaces of axles consisting of a
communicating tube from the wheel chamber containing the lubricant, radial
passages in coincidence or communicating therewith, an axial passage and radial
passages leading therefrom to the bearing surfaces, substantially as and for the
purpose hereinbefore described.
3. Means for the lubrication of the bearing surfaces of wheels and axles, sub-
stantially as and for the purpose hereinbefore described.
