PROVISIONAL SPECIFICATION.
Improvements in Hubs for the Wheels of Cycles and Common Road
Vehicles.
I, ROBERT FREDERICK HALL, of Sherlock Street, in the City of Birmingham,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
This invention relates to an improved construction of hub, and has for its principal
object, the adjustment of the ball bearing cups without the employment of screw
threads.
A hub constructed according to my invention consists of a tubular body or barrel
having inside coned entrances, with like outside coned cups taking and being
adjustable within them, and between bearing cones taking on the ends of the spindle
running axially through the barrel, and the insides of the cone adjusting cups, ball
bearings come.
Thus, the entrance to one end of the barrel is coned or slow-tapered, the taper
sloping upwards from the outer end, which may be closed or the metal turned over to
near the outside of the cone which screws up to a shoulder on the spindle and whose
neck protrudes a little beyond the said end of the hub.
Located within the interior of the said inside coned end of the hub is an outside
coned cup, between whose race and the ball cone on the spindle end, ball bearings
come, whilst a neck or flange on the end of the cup projects outwardly between the
neck of the screwed-on cone and the turned over end of the barrel to facilitate the
removal of the same by knocking out.
The ball cup is locked in its axially adjusted position by a screw peg passed through
the walls of the barrel.
The other end of the barrel of the hub is coned at its mouth end and tapers
inwards from the outside and against which a like outside coned cup, having balls
between it and a loose adjusting cone screwing on the spindle end and having a flat
for taking between the forks of the stays and so preventing rotation, takes its
bearing.
The entrance to this end of the barrel, outwards of the coned part, is inside screwed
for taking an outside wormed locking washer which is wormed therein up to the
outer face of the coned ball cup and locks the same in its adjusted position.
The said cone is prevented from turning by a screw peg passing through the
outside of the barrel, whilst the locking washer is retained by a screw pin, passing
through one or other of a series of radial slots formed through it and taking into a
screw hole in the face of the cup.
The entrances to the outside coned cups are inside screwed for the reception of
screwed-in ball-retaining washers or rings.
In back wheel hubs, the outside periphery of the right hand end of the barrel is
stepped to two diameters respectively right and left hand screwed to take the chain
wheel and its lock nut.
Dated this 28th day of May 1896.

I, ROBERT FREDERICK HALL of Sherlock Street, in the City of Birmingham,
Manufacturer, 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 stateinment :-
This invention relates to an improved construction of hub, and has for its principal
object the securing of the ball bearing cups or discs within the ends of the barrel
without the employment of screw threads.
A hub constructed according to my invention consists of a tubular body or barrel
having the ends inside coned or provided with conical seatings within which
corresponding outside coned ball-bearing cups, socket or take and are there fixed
whilst the ball bearings are located between adjustable cones taking on the screwed
ends of the spindle running axially through the barrel, and the insides of the
coned cups.
Thus, the entrance to one end of the barrel is coned or has a slow-tapered seating
the taper sloping upwards from the outer end which may either be left open or it may
be partly closed by the metal being turned over to near the outside of the cone
which screws up to a shoulder on the spindle (or may be adjustable) and whose neck
protrudes a little beyond the said end of the hub.
Located within the interior of the said inside coned end of the hub is an outside
coned cup between whose race and the ball cone on the spindle end, ball bearings
come, whilst a neck or flange on the end of the cup may project outwardly between
the neck of the screwed-on or adjustable cone and the turned over end or open end of
the barrel to facilitate the removal of the same by knocking out.
The ball cup is locked in its axially adjusted position either by a screw peg passed
through the walls of the barrel or by the taper on the cone cup.
The other end of the barrel of the hub is coned at its mouth end and tapers inwards
from the outside and against which a like or corresponding outside-coned cup, having
balls between it and a loose adjusting cone screwing on the spindle end and takes its
bearing.
The entrance to this end of the barrel outwards of the coned part is inside screwed
for taking an outside wormed locking washer which is wormed therein up to the outer
face of the coned ball cup and locks the same in its adjusted position.
The said cone is prevented from turning by a screw peg passing through the outside
of the barrel, whilst the locking washer is retained by a screw pin, passing there-
through and taking against or into the face of the cup.
The open mouths of the outside coned cups are inside screwed for the reception of
screwed-in ball-retaining washers or rings, and in back wheel hubs, the outside
periphery of one end of the barrel is stepped to two diameters respectively right and
left hand screwed to take the chain wheel and its lock nut.
Figure 1 of the accompanying drawing represents, in longitudinal vertical section,
a cycle back-wheel hub constructed and arranged according to my invention.
Figure 2 is an elevation of the chain-wheel end of the same showing the locking
washer by which the cup at that end is retained within the coned mouth of the hub
barrel.
Figure 3 represents an elevation and a section of the locking washer separately.
Figure 4 represents an elevation and a section of one of the coned cups and a section
of its ball-retaining ring.
Figure 5 is a longitudinal section of the barrel or body part of the hub separately.

page_text: Figure 6 shows a section of the other coned cup and a section and an elevation of
its ball-retaining ring, and
Figure 7 represents the spindle and adjustable cones which screw onto its wormed
ends, separated.
The same letters of reference indicate corresponding parts in the several figures of
the drawing.
a is the barrel or body part of the hub, having spoke flanges a¹, at its opposite ends,
and with the head a², at the left-hand end stepped to two diameters at a³, a', which
are respectively outside right and left hand screwed to take the chain wheel b, and its
lock nut . a, a are the inside coned or taper socketed ends of the barrel, the right
hand end being partially closed by turning over the metal at a', whilst the entrance to
the inside tapered or coned end is inside screwed at a", and d, e, are the ball bearing
cups or discs, coned or tapered exteriorly to correspond to and fit or socket within the
said inside-coned end seatings of the barrel, wherein they are affixed, the former by
small pins d', passed through the walls of the barrel, and into the recesses d, and the
latter by the small pins e', passed through the bead of said barrel and in recesses e, and
being further retained by the locking washer f, screwing into the entrance as, of the
hub and prevented from worming out by the small screw f', passed therethrough and
impinging or bedding against the face of the fixed cone e. 2, e are the ball races of
the cups or discs, wherein the balls g, are retained by the rings d³, e, screwing into
the wormed entrances of the same, whilst the coned cup d, has a collar d, extending
through the opening a, for facilitating the removal of the said cup by knocking out.
his the fixed spindle right-hand screwed at the ends h1, h2, and passing through
holes d, e, in the cups and a hole in the locking washer (whose face is sunken
with slots, or holes for taking a forked spanner or other tool for worming it out of
place) and with the screwed part h¹, terminating in a collar, whilst i, il are the
adjustable bearing cones, screwing on the wormed ends of the spindle and having part
ball-bearing race, . between which and the races d², e². of the cups, the balls run.
The cone i, preferably is screwed up against the spindle collar h', whilst the adjustment
of the bearings is effected by turning the cone i, in one or other direction, this
being conveniently effected by the application of a spanner to the flats, formed on
the end of same for that purpose.
After the cones have been adjusted up to the bearings, they may be locked in their
adjusted positions by nuts screwed on the spindle.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is
First. In hubs for wheels, providing or forming at the ends of the barrel, sleeve or
body part of the same, conical seatings or interiorly coned parts, wherein
correspondingly outside-coned ball-bearing cups or discs take or socket and are there
secured, without screwing.
Secondly. In hubs for wheels, the combination with exteriorly coned bearing cups
socketting into the corresponding taper ends of the hub body, of ball-retaining rings
or equivalents screwed into the open mouths of the said cups or discs.
Thirdly. The improvements in hubs, and the general construction, arrangement
and combination of the parts of the same, substantially as and for the purpose
described and set forth.
