Improvements in Means for Lubricating the Crank Spindles of Cycles.
HARRY WEBBER, Ashingdon Hall, near Rochford, Essex, Engineer, do hereby
declare the nature of this invention to be as follows:-
This invention is a method of oiling the main driving spindles of cycles by
means of two rings running loose on the spindle. These rings dip into an oil
bath as they turn with the spindle and carry the oil to the bearings. These rings
may be made any shape or size as convenient to manufacturer or to facilitate the
raising of the oil. The spindle is designed specially; also the hub or oil bath.
The hub is eccentric (larger in the middle than it is at the ends), therefore either
the rings must be made in pieces or the hub will be slotted at the top to allow
the rings to drop in & then be covered over. It is claimed to arrange these
mechanical details in the most suitable way.
The specially designed spindle differs from ordinary crank spindles of cycles
in one respect namely:-it requires two turned bearings surfaces for the oiling
rings to turn on. These surfaces will commence at the ball bearings and run
The
inwards, ending in a shoulder to prevent the rings from slipping off.
diameter of these surfaces will be a little less than the outside diameter of the
ring of balls when they are in position, thus allowing a space for the oil to run
in. The length to be made to suit the oiling rings.

Improvements in Means for Lubricating the Crank Spindles of Cycles.
HARRY WEBBER, Ashingdon Hall, near Rochford, Essex, Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention relates to the crank spindles of cycles and the object thereof
is to keep a flow of oil around the balls while the machine is in motion.
This is accomplished by means of two rings A and B which are caused to rotate
by the friction between the rings and the spindle C when in motion. These rings
dip into oil as they turn round and carry some of the oil to the spindle from
whence it runs onto the balls. The spindle differs from ordinary spindles in one
respect namely it has two bearing surfaces for the rings to run & shoulders to
prevent them slipping off. The ball races or cones D and E should be of the best

eccentric form with the centre of the spindle displaced somewhat from the centre
of the hub so as to make a reservoir for the oil to be in.
There will also be a guage to show when the oil is getting low in reservoir.
All parts shall, be made any size or shape, and of any material to suit manu-
facture.
Having now particularly described and ascertained the nature of my said
invention and what the same is to be performed, I declare that what I claim is:-
1. That the novelty of my invention is self-lubrication applied to the crank
spindles of cycles, that is to say the spindle in turning round causes oil to flow to
its bearings.
