PROVISIONAL SPECIFICATION.
Improvements in the Bearings of Cycles and other Common Road
Vehicles.
I, GRAHAM TEMPLE, of Featherstone Road, Kings Heath, near the City of
Birmingham, Commercial Traveller, do hereby declare the nature of this inven-
tion to be as follows:
This invention has reference to improvements in the construction of wheel
hubs, crank axle brackets, pedals and other anti-friction bearings of cycles and
common road vehicles, and has for its object, to render such bearings inore per-
fectly dust-proof and oil-retaining.
In carrying out one form of my invention as applied to a cycle wheel hub,
the spindle running axially through the body of the same carries two cones, hav-
ing ball races opposed to the ball races formed in the mouth ends of the hub as
usual. One of these cones is fixed and the other adjustable, and has an out-
wardly extending sleeve surrounding the spindle, somewhat similar to the
ordinary extension of the cone by which an adjustment is effected. The extreme
outside of one end of the hub body is screwed and receives a dust cap or cover,
which closes in the said end, and has a sleeve extending outwardly from it,
adapted to take and fit over the sleeve extension of the cone, whose end protrudes
to come extent beyond the outer edge of the dust-cap sleeve. As a further means
for excluding dust and retaining oil, I provide a supplementary cap or bush,
of such a size and internal diameter as to take closely over the sleeve extension of
the cap and completely cover or box in the extending end of the cone-sleeve,
connection between this outer cap and the cone being made by a projection on
the one part engaging in a recess on the other, or by flats, the cone coming
between suitable interior formations of the cap, or otherwise. A portion of the
said outer cap is annularly facetted or formed like a nut to receive a spanner,
and on being rotated in one or other direction thereby, the motion imparted to
it is transmitted to the cone, which is adjusted accordingly. It is understood
that when the hub is revolving, the outer cap is stationary, it being locked with
the cone to the spindle by the ordinary lock nut.
The arrangement of the parts at the other, or chain wheel end of the hub is,
generally, the same as described other than that the cap which screws onto the
end of the barrel has formed integrally with it, a lock nut or ring which bears
against the face of the chain wheel and locks the same to the hub.
Instead of the supplementary cap being keyed or otherwise connected to the
cone or the spindle it may be independent of them, that is, it may be simply in
the form of a loose or threaded-on bush or cap, with the one and open end coming
against the outside end of the principal dust cap, and with the lock nut taking
a bearing against the other end, which has a hole through it of sufficient size
only to take upon the spindle. Or the supplementary cap may be sufficiently
large to entirely close the principal dust cap, in which case the inner and open
end of the same would abut, or come close up to, the outer face of the spoke

page_text: flange. The sleeve on the primary dust cap surrounding the cone might in this
particular construction, be dispensed with and the cone extension would pro-
trude through a close fitting hole in the supplementary cap and have the usual
flats upon it for adjustment. The said additional cap may be secured to the
body of the hub by nuts, screwing or otherwise, or it may be keyed or coupled
to the conc.
The application of my invention to the bearings of cycle crank axle brackets,
cycle pedals and other parts of cycles and common road vehicles, differs in no
essential respect from its application to wheel hubs as herein described.

Improvements in the Bearings of Cycles and other Common Road
Vehicles.
I, GRAHAM TEMPLE, of Featherstone Road, Kings Heath, near the City of
Birmingham, Commercial Traveller, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement:-
This invention has reference to wheel hubs, crank axle brackets, pedals and
and other analogous bearing parts of cycles and common road vehicles, and has
for its object, to render such bearings more perfectly dust-proof and oil-retaining.
Figure of the accompanying drawings represents an elevation of a wheel
hub of the cup and cone type, constructed and arranged according to my inven-
tion.
Figure 2 is an end elevation, and
Figure 3a longitudinal vertical section of the same.
Figure 4 is another longitudinal vertical section of the said hub, with some of
the parts detached from the end.
Figure 5 represents a cross section of Figure 3, upon the dotted line ..
Figures 6, 7, 8, 9 and 10 represent different views of the detail parts.
The same letters of reference indicate corresponding parts in the said Figures 1
to 10.
According to the form of my invention represented in the said Figures 1 to 8,
the spindle a, running axially through the body of the hub b, carries two
cones a¹, a², respectively having ball races a³, a', opposed to the ball races b¹, 63,
formed in the cups 63, 64, fitted into the mouth ends of the hub as usual. The
cone a', is fixed, whilst the other a², (which is represented separately in side and
end elevation and longitudinal section in Figure 8) is adjustable and has an out-
wardly extending collar, surrounding the spindle, somewhat similar to the
collar extension of an ordinary hub by which the adjustment of the bearings is
effected. The extreme ends of the hub body are screwed at, and receive
detachable dust-excluding covers c, c¹, which (represented respectively in front
and edge view in Figures 7 and 9) rotate with the hub and close in the said ends,
and have sleeves &,, extending outwardly from them, adapted to take and fit
over the collar extensions of the cones, whose extreme outer ends protrude to
some extent beyond the outer edges of the cover sleeves. The cap c', at the chain
wheel end of the hub has combined with it, a locking ring c, by which the

page_text: chain wheel d, is locked in position. As a further means for excluding dust and
retaining oil, I provide at each end of the hub, a supplementary cap c, d, the
former being represented separately in back and front end view and side eleva-
tion in Figure 6, whilst the latter is represented in inner end elevation and side
elevation in Figure 10. These caps are of such a size and internal diameter as to
take over the sleeve extensions of the end covers and completely box in the
extending collars of the cones, whilst connection between the outer cap c, and
the adjusting cone a³, is made by a projection or key c³, on the one part engaging
in a recess aº, on the other as represented, or as a modification, by flats on the
cone coming between corresponding interior facets or equivalent formations of
the cap, or otherwise. A portion of the said outer cap is facetted at c³, or other-
wise formed to receive a spanner, so that by this arrangement, when the cap is
rotated in one or other direction there, the motion imparted to it is transmitted
by the key connection to the cone, which is also turned and the bearings of the
hub are adjusted accordingly. It is understood that when the hub is revolving,
the outer caps are stationary, being locked with the cones to the spindle by the
ordinary lock nuts f.
In applying my invention to front wheel hubs of the cup and cone pattern the
arrangement of the parts is the same as described in connection with a back
wheel hub, other than that the covers which screw onto the ends of the barrel
are the same at each end, the integrally-formed lock nut or ring, which in
the arrangement previously described, bears against the face of the chain wheel
and locks the same to the hub, being dispensed with.
Instead of the supplementary cap beng keyed or otherwise connected to the
adjusting cone or the spindle both caps may be loose or threaded-on with their
open ends coming against the outside faces of the screwed-on covers, whilst the
lock nuts take their bearing against the other and closed ends which have holes
through them of sufficient size only to take upon the spindle. Or the supple-
mentary caps may be sufficiently large to entirely enclose the screwed-on end
covers, in which case the inner and open ends of the same may abut, or come
close up to, the outer faces of the spoke flanges. The sleeves on these detachable
end covers, surrounding the cone collars might, in this particular construction,
be dispensed with, in which case the cone extensions would protrude through
close fitting holes in the non-rotating caps, and with the sleeve of the adjusting
cone having the usual flats for facilitating its rotation. The said additional
caps may be secured to the body of the hub by nuts, or by screwing or otherwise,
or they may be keyed or coupled to the cones.
Figure 11 represents the application of my invention to a disc-adjusting crank-
axle bearing or cycle bottom bracket, according to which, each of the discs a,
screwing into the mouths of the barrel b, of the bracket, has a sleeve extension a¹,
closely surrounding the rotating spindle c, and taking or socketting into a
recess d, in the inner face of the keyed-on crank d, thereby effectually excluding
dust from the bearings.
Figure 12 represents a disc adjusting wheel hub embodying my improvements,
cach disc a, having a sleeve a', through which the stationary spindle c, passes,
the said sleeve being boxed in, to render the bearings dust-proof, by a cap d, also
threaded on the spindle, up to the stop shoulder c', being clamped between this
shoulder and the fork end of a cycle framing (when the hub is in position) by
the nut f. Or instead of providing supplementary dust caps, the sleeves may
be enclosed or boxed in by corresponding recesses formed in the opposed sides of
the fork ends or equivalent parts of a cycle framing.
Figures 13 and 14 represent two modifications of my improvements applied to
crank axle bearings of the cup-and-cone type.
In Figure 13, each end a', of the barrel a, is outside screwed to take a dust-
excluding cover b, which has a sleeve b, closely surrounding the extension c
of the cone, which is carried by and rotates with the spindle c, over which is
lipped a boxing-in cap d, enclosing the cone, to which it may be connected by

page_text: a key or equivalent arrangement as described in connection with the hub shown
in Figure 1. This cap which rotates with the spindle, may be, but is not neces-
sarily, extended so as to partially enclose the cover b, and is secured in position
by the locking nut f, which is screwed onto a wormed part of the spindle, inwards
of the crank c.
In Figure 14, the arrangement of the parts is the same as that of Figure 13,
save that the lock nut f, is dispensed with, and that the dust-excluding cap d,
is made to retain the cone in position on the spindle by the eye , thereof being
internally wormed to screw onto the said spindle.
The application of my invention to pedals, and also to analogous bearings for
other wheeled vehicles, differs in no essential respect from its application to the
wheel hubs and crank axle bearings of cycles as herein described.
Having now particularly described and ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is.
·
First In cycle and other wheel hubs, bottom brackets and other bearings,
of the cup and cone type, excluding dust and rendering the bearings oil-retaining,
by providing the ends of the barrel or body with screwed on or detachable covers
having central sleeves surrounding the cones, or collar extensions of the cones,
which said sleeves and collars are boxed in by supplementary dust caps or equi-
valent enclosures, substantially as described and set forth.
Secondly-In cycle and other wheel hubs, bottom brackets and other bear-
ings of the cup and cone type, excluding dust and rendering the bearings oil-
retaining by providing the barrel or body with screwed-on end covers having
central sleeves surrounding collar extensions of the cones, which sleeves and
extensions are boxed in by supplementary caps or equivalent enclosures, with
the one cap connected with the adjustable cone by a key on the one taking into
a recess on the other or by analogous means, substantially as herein described
and set forth.
Thirdly-In cycle and other wheel hubs, bottom brackets and analogous
bearings of the disc adjusting type, providing the discs or cups thereof with
central sleeves, surrounding the spindle and enclosed or boxed in by supplemen-
tary caps or by recesses made in the opposed faces of the framing ends, cranks
heads or the like, substantially as and for the purpose as described and set forth.
