PROVISIONAL SPECIFICATION.
Improvements in the Construction of the Hubs of Wheels of
Velocipedes and other like Machines, and in the Mode of Fixing
the Spokes thereto.
We, JOHN ADDISON of Co-operative Buildings, Dalinuir in the County of
Dumbarton, North Britain, Engineer and ALEXANDER ADDISON of 110 Onslow
Drive, Dennistoun in the County of Lanark, North Britain, Engineer do hereby
declare the nature of this invention to be as follows:-
--
This invention relates to improvements in the construction of the hubs of wheels
of velocipedes and other like machines and in the mode of fixing the spokes thereto
and consists in constructing the inside of the hub with a recessed portion so that a
rim is left through which the end of the spoke is passed and the recess allows the
reception of the nut for screwing up the spoke, the spoke not being screwed into
the hub. By our said invention the wheel can be tensioned up correctly and the
arrangement also brings the spokes to the proper angle of the ring and hub. The
arrangement also allows an elasticity or yield which on a sudden shock to the wheel
prevents the spokes from breaking. Also the spokes can be readily replaced and
fixed in position by simply passing the end of the spoke through the rim, which is
the nut which is
left by the recess upon the inside of the hub, and screwing "boring, tapping
carried upon the free end of the spoke and within the recess.
or screwing of the hub is required in the replacing of a new spoke; also the same
style and size of spoke can be used as at present.

COMPLETE SPECIFICATION.
Improvements in the Construction of the Hubs of Wheels of
Velocipedes and other like Machines, and in the Mode of Fixing
the Spokes thereto.
We, JOHN ADDISON, of Co-operative Buildings Dalmuir, in the County of
Dumbarton, North Britain, Engineer, and ALEXANDER ADDISOx of 110 Onslow
Drive, Dennistoun, in the County of Lanark, North Britain, Engineer, 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 which relates to improvements in the construction of the hubs of
wheels of velocipedes and other like machines and in the mode of fixing the spokes
thereto, has for its object to provide means whereby the spokes may be easily placed
in position and also at the proper angle to the rim or tyre and hub so as to enable
the wheel being more correctly tensioned up and which also permits of an elasticity
or yield in the wheel so that when the wheel receives a sudden shock there is not
so much tendency for the spokes to bend or break, or the rim or tyre to buckle.
Also in accordance with our invention the spokes can at all times be easily repaired
as when a spoke does break the hub does not require any fresh boring or tapping
but simply to replace a new spoke and screw it up.
Referring to the annexed drawing which illustrates in cross section a hub A
and part of the spokes B of a cycle wheel made in accordance with our said
invention.
The said hub A (which is made of cast steel or other suitable metal) is formed

page_text: on the inside of each end with a recessed portion a having a slightly angled rim a'
which is provided with a number of holes so as to receive the ends of the spokes B,
the said spokes being passed through the said holes and screwed up by means of the
nut or nuts which are placed inside the recessed portion a as shown The said
angular rim a enables the spokes to fit the angle of the rim or tyre and the hub
better, and also permits of the wheel being more efficiently tensioned up than
hitherto.
The arrangement thus provides a hub which gives a certain amount of elasticity
or yield to the rim and spokes and so prevents damage to same by shocks, also
provides a better wheel, and one that can be very easily repaired as no fresh boring
or tapping of the hub is required but simply the placing in of a new spoke And
spokes of the same style and size as at present in use may be used, with the addition
of a nut or nuts, with this hub. The said recessed portions may if desired be
formed with their rims projecting outwards, from, in lieu of inwards to, the centre
of the hub.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is--
1st. Constructing the hubs of velocipedes and other like machines with a recessed
portion and rin at each end of the hub, into which the spokes are passed and
tightened up by muts, substantially as hereinbefore described and shown in the
annexed drawings.
2nd. The improved means of fixing the spokes of the wheels of velocipedes,
and other like machines, to their hubs, all substantially as and for the purposes
herein before described and shown in the accompanying drawings.
