NEW SELF LUBRICATING ROLLER WHEEL NAVE
Year: 1884

page_text: GILES PARKINGTON of 16 Newton Street, Blacksmith and JOHN CHEW of
Lambeth Street, Joiner and Builder, both of Blackburn in the County of Lancaster
do hereby declare the nature of the said invention for A NEW SELF LUBRICATING
ROLLER WHEEL NAVE to be as follows:-
1.
The Nave consists of an Iron shell bored out to receive an iron bush that fits on
the arm or axle, with a flange at each end of bush and has bearings for the Rollers
to work in, having three rollers fixed in the bearings of the bush, which work
against the shell of the Nave, the same will constantly stand in oil and the action
of the wheel carries the oil to all the bearings and working parts, thus allowing
the same to be. continually lubricated, the space required for the rollers increase
the surface or the diameter of the axle thereby causing less friction and enabling
greater loads or weights to be carried or drawn with comparative ease, the same
can be applied to existing arms or axles or can apply straight axles, the nave will
bave iron sockets cast on to receive the spokes of the wheel.

We GILES PARKINGTON, Blacksmith of N° 16 Newton Street and JOHN CHEW,
Joiner and Builder of Lambeth Street both of Blackburn in the County of
Lancaster, do hereby declare the nature of our invention for A NEW SELF
LUBRICATING ROLLER WHEEL NAVE and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
No 1 in drawing represents the Nave which is made of Iron, the inside of which
is bored out to receive the Bush, Axle and Rollers, which are all to be neatly fit
together. No 2 is the Axle turned up to fit in the bush and is keyed together at
No 9 with a steel key and the other end is screwed and has a nut as shewn. N° 3
are steel Rollers which work in the bearings of the Bush and against the inside
shell of the nave, the action of the wheel works the rollers, which constantly stands
in oil and carries it round and lubricates every part. N° 4 is the Bush turned up
at the flanges to fit inside the Nave and has necks and bearings for the rollers to
work in, and being keyed on the Axle the rollers are always in one position. N° 5
is a set screw which goes through a square washer one side of this washer fits
against one side of the nut which screws the Axle and Bush together as shewn, and
is screwed through the flange of the bush and acts as a lock nut to keep the axle
from working loose, and N° 10 is another set screw to be used when required for
oiling inside the nave. No 6 are the sockets cast in to receive the spokes of the
wheels. No 7 is a cap and has a knuckle fastener the cap fits on the end of the
nave and has an India Rubber ring placed between the Cap and Nave and is
tightened up with the bolt through fastener and cap as shewn, so as to make the
Nave to contain the oil. N° 8 is a washer which fits closely round the axle
between the bush and the nave nearest the cart bed so as to allow as little oil to
escape as possible.
We declare that what we claim is as follows
:
No 1 The boring out of the Nave to receive Bush, Axle and Rollers, and thereby
increases the size of the Axle, and N° 3 the Rollers working in the bearings of the
Bush which although largely increases the real circumference of the Axle, at the
same time the action of the Rollers when the wheel is in motion causes less friction
and makes it easier for the horse to takes its load.
N° 4 is the Bush which is keyed and screwed to the Axle as shewn for the
purpose of keeping the Rollers in their proper positions.
