PROVISIONAL SPECIFICATION.
Improvements in Cycle, and other like Vehicle, Adjustable Ball-
bearing Hubs, Crank-brackets and the like.
We, FRANK HULSE, of 133, Waverley Road, Small Heath, Birmingham,
Manager, and GEORGE NEWEY, of 76, Gerrard Street, Lozells, Birmingham,
Machinist, both in the County of Warwick, do hereby declare the nature of this
invention to be as follows:-
Our invention relates to improvements in cycle and other like vehicle adjustable
ball bearing hubs, crank-brackets, and the like, and has particular application
to the type commercially known as the "oil-retaining barrel kind of cup & cone
variety.
Describing our invention in connection with the hub of a safety bicycle in
which the spindle is fixed, and the hub shell or outer case revolves upon the same
with of course balls interposed between them; we (in order to make the whole
of the actual bearing, and consequently wearing, parts of the same easily re-
movable for repairs and the like) instead of shrinking, tinning and sweating, or
forcing, into the hub shell plain cylindrical ball-cups or dishes, internally tap
out the ends of the shell with screws of different direction, (left and right hand),
or of different pitches, and screw in the cups or dishes which are externally
threaded to correspond with the same, and by interposing between them a small
piece of tubing to serve as an abutment and spacing piece, they may be firmly
screwed, by a turnscrew engaging in suitable slots or other means, into position,
opposing and securing each other. The said spacing piece is held concentric
with the hub by its taking upon projections on the backs of the cups, or preferably
entering into recesses in the said backs of the cups and is better made of such
internal diameter as to coincide with that bore in the cups through which the
spindle passes allowing a ready flow of oil or lubricant to the bearing, the said
oil being supplied from the exterior of the hub shell through a small tube or
lubricator communicating with the spacing tube described.
To retain the oil in the bearing small washers externally screwed like the cups
are made to follow the latter into the hub shell and their bore through which
the spindle passes being of smaller diameter than the ball races in the cup, a
reservoir for the oil is formed.
The adjustment of the bearing is obtained in the usual way by means of the
lateral movement of the cone or cones along the fixed spindle, it or they being
screwed inwards to compensate for wear, etc.
The application to the crank bracket is same as that described with regard to
the hubs, but in this instance the outer shell or case is relatively fixed and the
spindle revolves.
Dated this Fourth day of October 1898.

page_text: admitted freely into the interior through the passage of the capped lubricator H,
and has a particularly ready flow to the balls by reason of our preferably making
the interior bore of the abutment tube C of a size coincident with that of the
holes through which the spindle passes in the cups B B. Or (Figures 3 and 4),
we may elect to provide small oil-admittance holes g g in the washers G G which
we should control by suitable spring covers X X, and in this case the abutment
tube C may not be employed, but instead of the tube, abutment shoulders c¹³,
against which to firmly screw the cups B B, provided in the outer shell A itself.
An alternate method of carrying out our invention without departing from the
spirit of the same is as follows:-The cups or dishes B B may be internally
screwed to allow of the oil-retaining washers G G being screwed into them, at
the same time using the abutment tube C for the purpose hereinbefore described
and shewn in Figures 1 and 2. The cups B B and washers G G made as just
described may be used in the containing shell A provided with shoulders c¹³
as shewn in Figures 3 and 4. Or instead of the shoulders, against which the
bearing cups B B are screwed, being on the inside of the shell A, (shewn in
Figures 3 and 4), a shoulder for the same purpose may be provided on the outside
of the bearing cups B B in such way as to engage upon the faces or ends of the
shell when the cups are screwed into position; cups having shoulders thus, have
the oil-retaining washers screwed into them as herein before described. Or again
we may make the equivalent of the oil retaining washer solid with any of the
cups B B herein described in lieu of the separate washers illustrated in Figures 1,
2, 3 and 4.
The adjustment by which we are to set up the bearings is provided for by
reason of one or both of the cones E E upon the screwed spindle F being capable
of lateral movement in either direction and being locked in the desired position
simply by their respective nut or nuts I I with the addition in some cases of
one of the well-known kind of D-holed plain, conical, or pegged washer to prevent
the accidental movement of the cone while the nut is being fastened. This same
property of the cones admits of their total removal from the spindle when requisite
or desired.
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:
1st. In a cycle or other like vehicle adjustable ball bearing hubs, crank-
brackets, and the like, of the type illustrated and described (in which the force
exerted on the balls by the cups is in an outward direction), the screwing in of
the ball cups or dishes against shoulders or abutments substantially as herein-
before described and illustrated in Figures 1, 2, 3 and 4.
2nd. The combination of the several parts substantially as herein before de-
scribed and illustrated in Figures 1 and 2.
3rd. The combination of the several parts substantially as herein before de-
scribed and illustrated in Figures 3 and 4.
Dated this Twenty-sixth day of June 1899.
