COMPLETE 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 and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
This invention relates to hubs for the wheels of cycles and common road
vehicles.
My improved hub has end caps with inside half ball-races and cones upon the
spindle having corresponding half ball races, the holes through the cones being
wormed to take upon the right hand screwed ends of a spindle directed axially
through the hub, whose right-hand end cap is right hand worined and the left-
hand end cap left hand wormed, each cap taking into correspondingly wormed
entrances to the barrels of the hub. Serewing on to the extreme ends of the
spindle, outwards of the cones (which are of hardened and tempered steel) are
soft steel or soft metal shouldered screw washers, with opposite facets upon one of
them for effecting its adjustments.
In a front wheel hub, the shouldered ends of the said washers take into the
holes in the ends of the front forks and in a back wheel hub the same take either
into slots in the fork ends or into holes in the chain adjustment rings or equivalent
parts. The whole of the parts of the hubs are locked in their adjusted positions
by nuts screwed onto the spindle ends and abutting against the outsides of the
forks.
Figure 1 of the accompanying drawing represents a complete longitudinal
vertical section of a cycle back-wheel hub constructed according to my invention.
Figure 2 is an elevation of the left hand end of the same.
Figure 3 represents an end elevation, a section and a plan of the soft metal or
soft steel screw washer at the left hand end of the hub, separately and
Figure 4 represents a section and an end elevation of the soft steel screw
washer (which is non-adjusting) at the right hand end of the hub.
The same letters of reference indicate corresponding parts in Figures 1 to 4 of
the drawing.
a is the hub with a barrel a', having mouth ends a³, a³, the latter being
exteriorly fitted with a chain wheel a. The said mouth ends are inside screwed
and take inside ball-race-cupped closure caps a, a, with the right hand cap a³,
being right band wormed and taking into the correspondingly wormed mouth
end a, whilst the left hand side cupped cap a, is outside left-hand wormed and
takes into the inside correspondingly wormed mouth end a².
band b' are right and left hand cones screwing upon the wormed ends c', c³, of a
spindle c and with ball bearings d, coming between the opposed half ball-races a', b³,
of the end caps and cones respectively.
e,
el are screw washers or nuts made of soft steel, and with their inner faces
sunken at e, and their outer parts collared at e³, and with the left hand washer e,
having flats or facets e, for rotating the same by a spanner when the collared
parts are in their assigned positions in the fork ends or the like. The sunken
parts of these washers take over the outwardly extending tips 64, of the cones
and the inner faces e, take into sinkings as, in the outer faces of the caps a³, a°.

page_text: The hubs of front wheels are constructed exactly the same as the back wheel
hub described, with the exception that they are not fitted with chain wheels.
By the right hand closure cap being right hand wormed and screwing into a
correspondingly wormed entrance to the hub and the left hand cap being left
hand wormed and screwing into the like wormed other entrance, the friction of
the balls acting upon the ball cups of the caps tends to tighten up the said caps
and prevents them from coming loose. Thus, as the prevailing direction of motion
of the hub is from left to right and as the screwing at both ends is relatively in a
contrary direction, the friction or drag of the balls rolling over the ball races of
the cups acts the same as an intermediate wheel or pinion and so keeps the caps
always screwed up full home consequent upon the traversing motion being in a
direction contrary to that which would unscrew the caps.
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 :-
The combination with wheel hubs of the construction herein described, of
inside screwed end washers or nuts preferably made of soft steel or soft metal and
screwing onto the outside screwed ends of the spindle substantially as and for
the purpose described and set forth.
Dated this 25th day of June 1896.

A Dust-proof Cap for Cycle Pedal and other Bearings.
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 statement :-
This invention relates to a dust-proof lubricating cap for the bearings of pedals.
and other parts of cycles and common road vehicles.
Figure 1 of the accompanying drawing represent a dust-proof lubricating cap
constructed according to my invention and fitted to the end plate of a cycle
pedal.
Figure 2 is a section of the same.
The object of my invention is a neat and efficient means of closing the oil aperture
and it consists of a disc f, working within a sinking g', of a dust-proof cap g, and:
turning upon a pivot 92, and with a fixed stop g³, formed from the metal of the cap,
taking into a cut-away part 9, of the disc, so as to limit the extent of the movement
of the said disc and bring the hole f, in the disc when in one position coincident
with the oiling aperture 9, in the cap.
When the holes f, g are coincident then the bearings can be supplied with oil,.
but when not coincident, the oil aperture is closed by a solid part of the disc and.
the access of dust or dirt. to the bearing is prevented.
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.-
In cycle pedal and other bearings, the combination with a dust-proof cap, having
an oil hole through it, of a revolving disc also having an oil hole through it and
limited in its motion by a stop, substantially as and for the purpose described.
and set forth.
