page_text: I, ALBERT FARNELL, of 62, Manningham Lane, Bradford, Yorkshire, Cycle Factor,
do hereby declare the nature of this invention to be as follows:-
My invention relates to the hubs of wheels, especially the ball bearing hubs of
suspension wire-spoked wheels, such as are employed in velocipedes and autocars.
The principal objects of my invention are facility and cheapness of manufacture, and
I attain them in the manner hereinafter described.
In constructing a hub for a running wheel, such as the front wheel of a rear-
driving safety bicycle, I take a piece of tube and two circular discs. The tube forms
the body of the hub and parts of the discs form the spoke flanges. Each disc is
pressed into the shape of a hat the cylindrical portion of which is fitted into the end
of the tube and there secured by brazing, soft, soldering, pressing or by projections
on one engaging in recesses in the other or by other suitable means. The wheel
axle is adapted to pass through an aperture formed in the centre of the disc.
This aperture may be of comparatively small diameter so as to leave a flange, and
the part connecting this flange with the cylindrical portion and the adjacent parts
may form a
race for the balls in a cone-adjusting bearing. Or the flange may
merely form a stop against which the back of a separate hardened bearing cup let
into the cylinder may bear; in this case the flange may be of reduced depth. Or
the flange may be dispensed with altogether and the cup formed with a lip on its
outer edge to prevent its being forced too far into the body of the hub. In a
cup-adjusting hub also the flange is preferably dispensed with and the interior of
the cylindrical part of the disc is tapped to receive the screw threaded cup. When
the two discs are fixed in position both ends of the hub can be tapped at one
operation; if this were attempted with the discs fitted on to the exterior of the
tube it would be necessary to cut the thread continuously from end to end of the
tube, involving considerable time and expense and the use of a heavy tube.
But by fitting the cylindrical parts of the discs within the ends of the tube they
form portions of reduced internal diameter which alone receive the thread while
the tube itself is not cut by the tapping operation.
In constructing a hub for a wheel fitted with a toothed pinion, such as the driving
wheel of a rear driving safety bicycle I make one end as above described, but at
the pinion end I fit the cylindrical portion of the disc around the exterior of the end
of the tube, with the free edge of such cylindrical portion directed away from the
middle part of the tube; and I screw thread the exterior of such cylindrical portion
in a suitable manner to receive the said pinion. In this case a separate piece may
be secured within this end of the tube to form the ball race or to receive the bearing
cup; or the cylindrical portion of the disc may be continued over the end of the
tube and returned within the said tube for the purpose. In all cases the exterior
vertical portion of the disc forms the spoke flange and such spoke flange may
either be set at the end of the tube or; by using a returned cylindrical portion as
above described, the spoke flange may be set in from the end of the tube.

similar manner, making such modifications, if any, as special circumstances may
call for.
Deted this 19th day of Febrúar 1807
I, ALBERT FARNELL, of 50, (late of 62) Manningham Lane, Bradford, Yorkshire,
Cycle Factor, 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:
My invention relates to the hubs of wheels especially the ball bearing hubs of
"suspension, wire-spoked wheels, such as are employed in velocipedes and autocars.
The principal objects of iny invention are facility and cheapness of manufacture and
I attain them in the manner hereinafter described. Sectional drawings are appended
in order that the invention may be more perfectly understood and readily carried into
effect, but I do not confine myself to the precise details shown therein as these may
obviously be modified without departing from the spirit of my invention. The same
reference numerals indicate the same or corresponding parts throughout the
drawings.
In constructing a hub for a running wheel, such as the front wheel of a rear driving
safety bicycle, I take a piece of tube 2 and two circular discs 3, 3. The tube forms
the body of the hub and parts of the discs form the spoke flanges. Each disc is
pressed into the shape of a hat, the cylindrical portion 5 of which is fitted into the
end of the tube 2 and there secured as shown in Fig. I, by brazing, soft soldering,
pressing, or by projections on one engaging in recesses in the other, or by other suit-
able means. The wheel axle is adapted to pass through an aperture 6 formed in the
centre of the disc. This aperture may be of comparatively small diameter so as to
leave a flange 7, and the part connecting this flange with the cylindrical portion and
the adjacent parts may form a race 8 for the balls in a cone adjusting bearing as
shown at the left end of Fig. I. Or the flange 7 may merely form a stop against
which the back of a separate hardened bearing cup 9 let into the cylinder may bear;
in which case the flange may be of reduced depth, all as shown at the right end
of Fig. I. Or the flange 7 may be dispensed with altogether and the cup 9 formed
with a lip 10 on its outer edge to prevent its being forced too far into the body of the
hub, as shown at the right end of Fig. II.
In a cup adjusting hub also the flange 7 is preferably dispensed with and the
interior of the cylindrical part 5 of the disc 3 is tapped to receive the screw threaded
cup 9, as shown at the left end of Fig. II. When, in a cup adjusting hub, both
discs 3, 3 are made without the flanges 7, 7 and are fixed in position, both ends of
the hub can be tapped at one operation; if this were attempted with the discs fitted
on to the exterior of the tube, it would be necessary to cut the thread continuously
from end to end of the interior of the tube, involving considerable time and expense
and the use of a heavy tube. But by fitting the cylindrical parts 5 of the discs
within the ends of the tube they form portions of reduced internal diameter which
alone receive the thread while the tube itself is not cut by the tapping operation.
In constructing a hub for a wheel fitted with a toothed pinion 12, such as the

page_text: driving wheel hub of a rear driving safety bicycle I may make one end as above
described, but at the pinion end I secure the cylindrical portion 5 of the disc around
the exterior of the end of the tube, with the free edge of such cylindrical portion
directed away from the middle part of the tube; and I screw thread the exterior of
such cylindrical portion in a suitable manner to receive the said pinion as shown in.
Fig. III. In this case a separate piece 13 may be secured within the end of the
tube to forin the ball race or to receive the bearing cup. Or the cylindrical portion 5
of the disc may be continued over the end of the tube and returned within the said
tube for the purpose as shown in Fig. IV.
In all cases the exterior vertical portion 4 of the disc forms the spoke flange and
such spoke flange may either be seb at the end of the tube as shown in Figs. I and II
or by using a returned cylindrical portion as above described, the spoke flange may
be set in from, the end of the tube, as shown at both ends in Fig. IV.
It will be obvious that various combinations of the several parts of my invention
may be made without exceeding the limits thereof. In applying my invention to
other hubs than those above described I proceed in a similar manner, making
such modifications, if any, as special circumstances may call for.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I
claim is:-
1
1. A wheel hub, constructed of a tube forming the body and of two centrally
perforated hat-shaped discs, the outer vertical portions of which discs form the spoke
flanges while the cylindrical portions thereof are secured within the ends of the tube
and are provided with internal flanges to form the ball races, or are tapped or
otherwise adapted to receive separate bearing cups, substantially as herein described.
2. In a wheel hub of the kind provided with a toothed pinion at one or each end,
securing the cylindrical portion of a centrally perforated hat-shaped disc around the
exterior of the end of the tubular body of the hub, and screw threading the said
cylindrical portion externally to receive the said pinion, substantially as herein
described.
3. In a wheel hub of the kind provided with a toothed pinion at one or each end,
securing the cylindrical portion of a centrally perforated hat-shaped disc around the
exterior of the end of the tubular body of the hub and screw threading the said
cylindrical portion externally to receive the said pinion, and securing a separate piece
within the said end of the tube to form the ball race or to receive the bearing cup,
substantially as herein described.
4. A wheel hub, constructed of a tube forming the body and of two centrally
perforated discs, the outer, vertical portions of which discs form the spoke flanges,
while the cylindrical portions are returned within themselves so as to fit both around
and within the ends of the tube and are provided with internal flanges to form the
ball races, or are tapped or otherwise adapted to receive separate bearing cups,
substantially as herein described.
5. The several constructions, combinations and arrangements of parts constituting
my improved hubs for wheels, substantially as herein described and as illustrated by
the accompanying drawings.
