PROVISIONAL SPECIFICATION.
Improvements in or connected with Hubs for the Wheels of
Velocipedes and other Vehicles.
We, GEORGE SINGER, Managing Director of Singer Cycle Co. Ltd. and FRANK
BAGNALL, Foreman, both of Singer Cycle Works, Coventry, in the County of
Warwick, do hereby declare the nature of this invention to be as follows:-
This invention refers to the adjustment of the bearings of the hubs for velocipedo
and other wheels, and also refers to the fixture of the sprocket wheel upon the
rear hub.
According to our invention we form the hub of the so-called "barrel" pattern,
that is, adapted to receive centrally a fixed spindle having collars formed thereon,
against which collars the balls have bearing. At one end we screw within the
barrel of the hub a cup, which, when in proper position, is permanently fixed, and
retains a ring of balls between itself and the adjacent flange of the fixed spindle.
The opposite end of the hub we screw thread internally, and at the tubular end
thereof we form a tapered or conical edge, extending outwards.
The cup for this end of the hub, we make somewhat longer than such
cups are
usually made; the said cup being adjusted to position and retaining the ring of
balls between itself and the flange of the fixed spindle, wo then lock the cup by the
following means: We provide a ring screwed internally to take on to the end of the
adjustable cup, and we form the said ring with a conical edge so that when screwed
up the said edge engages with the tapered tubular ond of the hub, and thereby is
securely held, together with the cap by which the ring is carried.
In some cases we may split the coned and screwed ring, in such manner that its
contact with the tapered end of the hub will cause it to be contracted.
By the arrangement and construction of the devices as described, we are enabled
to obtain a very effective and simple locking of the ball cups.
The coned rings may be rotated to released or fix tho cups, by any convenient
means, we however find a convenient means to consist in the formation of radial
notches in the periphery of the ring and we provido a spanner with teeth or a
tooth to take into such notches.
In constructing the fixed cup of the rear hub we provide the said cup with an
end flange, and we screw thread the exterior projecting end of the hub barrel, to
receive the rear sprocket wheel. The sprocket wheel having been placed in position
on the hub barrel, we then screw in the flange cup, and the flange of same coming
into contact with the sprocket wheel, the perfect looking of both the sprocket wheel
and cup is obtained.
We do not limit ourselves to scrowing on the sprocket wheel, as such may in
some cases be applied by keys, dogs, or in any other usual manner.

Velocipedes and other Vehicles.
We, GEORGE SINGER, Managing Director of Singer Cycle Co. Ltd. and FRANK
BAGNALL, l'orenan, both of Singer Cycle Works, Coventry, in the County of
Warwick, 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 :-
According to our invention we form the hub A substantially as shewn in section
at Fig. 1, and end view Fig. 2, say of so-called "barrel" pattern, that is, adapted
to receive contrally a fixed spindle B having collars B' B' formed thereon, against
which collars B' the balls C have bearing. At one end we screw within the barrel
of the hub A a cup D, which when in proper position, is or may be permanently
fixed and retains a ring of balls C, between itself and the adjacent flange B' of the
fixed spindlo B. The opposite end of the hub A wo screw thread internally, and at
the tubular end A¹ thereof we form interiorly a tapered or conical part oxtending
outwards.
The cup E for this end of the hub A we make somewhat longer than auch oups
are usually made; the said cup E being adjusted to position and retaining the ring
of balls C between itself and the adjacent flauge B₁ of the fixed spindle, we then
lock the cup E by the following means: We provide a ring F screwed internally to
take on to the end of the adjustable cup E, and we form the said ring F with a
conical exterior part F so that when screwed up the said edge or part F¹ engages
with the tapered tubular end A' of the hub A, and thereby is securely held, together
with the cup E by which the ring F is carried.
In some cases we may split or divido the coned and screwed ring F, in such
mannor that its contact with the tapered end A' of the hub A will cause it to be
contracted.
By the arrangement and construction of the devices as described we are enabled
to obtain a very effective and simple locking of ball cups.
The coned rings F may be rotated to release or fix the cups E by any convenient
means, we however find a convenient means to consist in the formation of radial
notches F Fig. 2 in the periphery of the ring F and we provide a flat spanner, the
head of which is shown at Fig. 6 with teeth G or a tooth to take into such notches,
while the segmental part bears against the circular edge of the ring F.
In constructing the fixed cup D of the rear hub Figs. 1 and 2 we provide the said
cup D with an end flange D', and we screw thread the exterior projecting end A*
of the hub barrel to receive the rear sprocket wheel, which is similarly sorew-
threaded. The sprocket wheel, not shown in the drawings, having been placed in
position on the hub barrel A, we then screw in the flanged cup D, and the Hange D¹
of same coming into contact with the sprocket wheel the perfect looking of both the
sprocket wheel and cup is obtained.
We do not limit ourselves to screwing on the sprocket wheel as such may in some
cases be applied by keys, dogs, or in any other usual manner.
Fig. 3 shews a front wheel hub the construction of which is exactly similar to the
rear wheel hub described with reference to Figs. 1 and 2.
Fig. 4 shews in sectional elevation and Fig. 5 in ond view a bottom bracket or
crank axle bearing with our invention applied; the general construction thereof is
similar to that previously described with reference to Figs. 1 and 2, and the several
parts are accordingly marked with corresponding letters of reference.

page_text: Having now particularly described and ascertained the nature of this inven-
tion, and in what manner the same is to be performed we declare that what we
claim is :-
1. In ball bearings for velocipedes and other vehicles the means for fixing or
locking a ball retaining cup, consisting of a ring threaded internally to screw onto
the end of the cup, and having a tapered or conical outer periphery engaging, when
in its fixing position, with circular tapered recess in the end of the part by which
the cup is carried, as set forth.
2. In ball bearings for velocipedes and other vehicles, the combination with a
fixed or revolving spindle or axle having collars fixed or formed thereon, of an
outer barrel or tubular part A, a cup screwed endwise therein, to confine an annulus
of balls between itself and a collar on the spindle or axle, and a ring screwing onto
the end part of the cup, such ring having an exteriorly tapered or coned surface,
to engage an interiorly tapered end of the barrel or tubular part A, and thereby
to retain the cup in position, together with means whereby the ring may be revolved,
substantially as described.
3. The construction and arrangement of bearings with the means for locking the
parts in position, all combined and acting substantially as and for the purposes
described and illustrated with reference to Figs. 1 to 5 of the accompanying
drawings.
