PROVISIONAL SPECIFICATION.
Improvements in or connected with the Lubricating Caps of the
Axles of Carriages and other Road Vehicles.
I, SAMUEL WILSON, of Buxton Street, London Road, Manchester, in the
County of Lancaster, Mechanical Engineer, do hereby declare the nature of this
invention to be as follows:-
The object of the invention is to provide means of lubricating the bearings of
the wheels upon the axles without removing the cap.
It consists essentially of an oil receiver placed on the outside end of the cap
constructed with an inner and outer shell or part one of which rotates within the
other, each provided with an aperture opening to the outside, and the inner one
communicating with the inner side of the cap, when the two outer holes are brought
to coincide together oil can be poured in through to the interior of the cap.
In carrying out the invention I construct the cap in the ordinary way, and in a
face or end of it I bore or drill a hole of any required size. 1 then construct the
oil receiver with two shells or tubes, one placed inside the other, the inner one
being provided with a milled head on the outside, and secured to the outer one by
a washer riveted or otherwise attached on the inner side. The two are then secured
to the cap by means of a flange riveted on. A hole is drilled through the two
tubes, and the outer one provided with a milled head whereby it can be turned
round to bring the two holes to coincide. The aperture is closed by turning the
inner tube part of a revolution.
For new caps, instead of the outer tube riveted onto the face of the cap, a socket
may be cast thereon and bored to the required size, and the inner tube fitted therein
and riveted over on the inner side, the outer end of the tube, as before, being fitted
with a milled head.
I am quite aware it is not a novel idea to provide a hole in the end of the cap
through which oil may be inserted, as such has been previously attempted with a
spring plug to cover the hole, and such does not form any part of my invention.

COMPLETE SPECIFICATION.
Improvements in or connected with the Lubricating Caps of the
Axles of Carriages and other Road Vehicles.
I, SAMUEL WILSON, of Buxton Street, London Road, Manchester, in the
County of Lancaster, Mechanical 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 :-
The object of the invention is to provide means of lubricating the bearings of
the wheels upon the axles without removing the cap.
It consists essentially of an oil receiver placed on the outside end of the cap
constructed with an inner and outer shell or part one of which rotates each provided
with an aperture opening to the outside, and the inner one communicating with the
inner side of the cap when the two outer holes are brought to coincide oil can be
poured in through to the interior of the cap.
It will be fully described with reference to the accompanying drawings in which
as an example it is shown applied to the cap of a carriage wheel.

Fig. 4. Front elevation.
Fig. 5. Longitudinal section showing a modified form.
Fig. 6. Transverse section of same.
The сар A is constructed in the usual way and in the face or end of it I bore or
drill a hole a of any desired size.
The oil receiver or lubricator B is constructed with two shells or tubes C D one
placed inside the other, one fixed to the face of the cap A and the other capable of being
rotated thereon. Holes are drilled in the tubes through which the oil can be
poured. The holes are closed by turning one of the tubes upon the other.
In Figs. 1 to 4 the inner tube C is inserted in the hole a and is rivetted or
otherwise secured to the face of the cap and around it rotates the outer tube D
which is held in position by the flange c in the free end of the inner tube C. The
inner tube is provided with three holes and the outer tube with one hole . The
edge of the tube D is milled to enable it to be easily rotated or turned round to
bring the hole over one of the holes b.
In Figs. 5 and 6 the outer tube D is inserted in the hole a and is secured to the
face of the cap A by rivets passing through the flange d. The inner tube C is
secured to the outer one D by the inner end being turned or rivetted over. The
inner tube C is also provided with a milled head c whereby it can be turned round
to bring the two holes to coincide.
For new caps instead of one of the tubes being rivetted on to the face of the
cap a socket may be cast thereon and bored to the required size and the other tube
fitted to it the outside being milled for the purpose of turning it.
I am quite aware it is not a novel idea to provide a hole in the end of the
cap through which oil may be inserted as such has been previously attempted with
a spring plug to cover the hole and such does not form any part of my invention.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. A lubricating cap for the axles of carriages provided on its face with an oil
receiver constructed of two tubes placed one upon the other one of which
communicates with the interior of the cap and the other forms a cover for the holes
therein substantially as described and shown.
2. The combination with the axle cap of the two tubes CD communicating
with the interior of the cap and provided with inlet boles bone of which is
affixed to the face of the cap and the other free to rotate substantially as described
and shown.
