Improvements in Driving Hubs and Chain Wheels for Cycles and
the like.
I, JOHN HOWARD l'LANT, of Abberley Works, Abberley Street, Dudley, in the
County of Worcester, Manufacturer, do hereby declare the nature of this inven-
tion to be as follows:-
.:
The object of my invention is to improve driving hubs and chain wheels for
cycles and the like in the following respects:-
--
On the outer shell of my hub to which the driving wheel is to be fitted (which
shell may be made of any convenient pattern) I make for the undermentioned
purpose a projecting rim or shoulder. The chain wheel I make with a boss in
the centre of the inner side for the purpose of screwing into the end of the shell
on which such shoulder is formed. In the same side of the chain wheel at the
base of and around such boss I cut a recess into which the said shoulder fits when
the boss is screwed into the shell. The two parts when screwed together may
be locked by a key or screw fitted partly in the shoulder of the hub shell and
partly in the chain wheel. Before the parts are so screwed and fitted I cup out
the said boss to form the ball race.
CONT DE DECIFICATION.
Improvements in Driving Hubs and Chain Wheels for Cycles and
the like.
I, JOHN HOWARD PLANT, of Abberley Works, Abberley Street, Dudley, in the
County of Worcester, Manufacturer, 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 relates to an improved hub for the driving wheels of cycles and
the like, and it consists in constructing one of the discs or cups adapted to be
screwed into the barrel of the hub in one piece with the driving chain wheel

page_text: whereby the number of parts is reduced, the construction simplified and the cost
of manufacture lessened.
In the accompanying drawing which shows by way of illustration this inven-
tion applied to a ball bearing hub:-
Figure 1 is a view in section showing one method of carrying my invention
into practical effect.
Figure 2 is a view in end elevation thereof.
Figures 3 and 4 are similar views showing a modification, and
Figures 5 and 6 are similar views showing another modification.
Throughout the views similar parts are murked with like letters of reference.
Referring to Figures 1 and 2. The hub consists essentially of a barrel such
as A having flanges or their equivalents to receive the spokes and threaded inter-
nally at its ends, of a disc or cup B screwed into one end of the barrel, of a com-
bined disc or cup and chain wheel C screwed into the other end of the barrel, of
the usual axle D carrying cones I and E, and of balls or spheres F. The axle D
is provided with the usual washers and lock nuts.
The adjustment of the bearing may be effected by means of one or both of the
cones E, E, qn the axle in the well-known manner.
The combined disc or cup and chain wheel C consists essentially of a ring c
having teeth at its periphery and a boss forming the disc or cup, the said
boss being threaded externally to adapt it to be screwed into one end of the
barrel A of the hub.
In the back of the ring c exterior to the boss is a recess c³ into which the
end of the barrel A-which preferably has an enlargement or flange a―fits when
the combined chain wheel and cup is screwed home.
The combined chain wheel and disc or cup C may be locked to the barrel A of
the hub after it is sorewed home either by means of one or more screws such
as F threaded into the ring c and into the enlarged end a of the barrel A. of the
hub as shown by Figures 1 and 2, or by means of a loose ring G screwed into
the recess which is threaded to receive it and engaging with the flange or
enlargement a on the end of the barrel A as shown by Figures 3 and 4. When
the barrel of the hub is made with flauges the screwed lock ring G is cut through
on one side like a piston ring, so as to permit of it being sprung over the shoulder
on the end of the hub, or it may be made in two parts hinged or otherwise suit-,
ably connected.
Instead of screwing the combined chain wheel and disc or cup into the barrel
of the hub it may be made a very good fit and simply pressed in, in which case
the following alternative method of locking the parts together may be employed.
Referring to Figures 5 and 6 the recess in the back of the ring c is made eccen-
tric with the boss c, and the flange a on the barrel of the hub is made eccentric
to engage with and fill this recess when the parts are pressed home, the two parts
being fixed together by means of a loose ring such as H screwed into the recess c
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-
(1) The improvements in hubs for the driving wheels of cycles and the like
substantially as herein described and illustrated by the accompanying drawing.
(2) In a ball bearing hub for cycles and the like, the combined chain wheel
and disc or cup, as and for the purpose set forth.
(3) In a hub for the driving wheels of cycles and the like, forming one of
the discs or cups of the bearing in one with and on the inner face of the chain
wheel and mounting and fixing it to the said hub, as and for the purpose set
forth.
(4) The combination with the hub of the driving wheel of a cycle and the like,
of a combined chain wheel and disc or cup adapted to fit in one end of the hub,

page_text: of an adjustable disc or cup in the other end of the hub and of means for looking
the combined chain wheel and disc or cup to the hub, as set forth.
