Improvements in Means for Securing Spokes to Wheel Hubs for
Common Road and other Wheeled Vehicles.
I, WILLIAM THOMAS PITT of the Firm of W. T. Pitt and Company of
24 Mary Street, Kenyon Street in the City of Birmingham, Cycle Manufacturer,
do hereby declare the nature of this invention to be as follows:-
This invention has relation to means for securing wire or rod metal spokes to
bubs of the wheels of wheeled vehicles and is particularly applicable to the wheels
of common road vehicles, although the same may be used in connection with carrier
and like cycles.
According to my improvements the heads or ends of the hub are made
segmental and the inner ends of the spokes are secured by clamping them between
the opposed faces of the said segments when brought together and secured one to
another.
In carrying out my invention the heads or ends of a hub have flanges, whose
outer faces are radially sunken to the depth of a little less than half the diameter.
of the inner ends of the spokes, which sinkings or recesses are inwardly terminated
by cross-directed and outwardly countersunk holes, wherethrough the spokes are
passed and threaded. That part of the face of the flange inward of the laterally
or cross directed holes is set back from the outer part wherein the sinkings come.
Each end of the hub is fitted with a flanged cap or disc having half sinkings in
its face corresponding to and coincident with the half sinkings in the ends of the
hub and between the inner ends of the said sinkings on the cap are studs or lifts, of
a height equal to the depth of the set back inner part of the face of the head,
which studs form as it were an annular collar for keeping the cap central or in
position upon the head, so that when the opposed faces of the flange end of the
head and cap or disc come together, the spokes, which have been threaded
through the holes in the flanges, seat themselves in the sinkings and are there
clainped.
Thus, the spokes, whose inner ends are hook-shaped and headed, are (when the
cap is removed) passed from the inner side of the flange through the holes therein,
and then on the hooked ends coming up to the said flange, the said spokes are
raised from a horizontal to a vertical plane, which brings the shanks of the said
inner ends partly to lie within the sinkings. The spokes being in this position,
then fit on the cap, when the sinkings on its opposed face take over the out-
standing halves of the spoke end, when by fixing the cap in its home position by.
small screws or otherwise the spokes are clamped between the cap and the flange
and fixedly secured in position, the thrust of the said spokes coming upon their
own hooked ends.
Instead of the holes passing through the metal of the bead at the junction of
the set-back part with the plain part they may pass through plain parts only, and
further, instead of employing separated collar studs or lifts we may employ in lieu
thereof a continuous horizontal ring collar, which when in position, takes and fits
tightly up to the inside walls of the sunken part of the head, thereby excluding
dirt and making a tight joint.

Improvements in Means for Securing Spokes to Wheel Hubs for
Common Road and other Wheeled Vehicles.
I, WILLIAM THOMAS PITT of the Firm of W. T. Pitt and Company, of
24 Mary Street, Kenyon Street, in the City of Birmingham, Cycle Manufacturer,
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 has relation to means for securing wire or 1od metal spokes to
hubs of the wheels of wheeled vehicles and is particularly applicable to the wheels
of common road vehicles, although the same may be used in connection with
carrier and like cycles.
According to my improvements the heads or ends of the hub are made
segmental and the inner ends of the spokes are secured by clamping them between
the opposed faces of the said segments when brought together and secured one to
another.
In carrying out my invention the heads or ends of a hub have flanges, whose
outer faces are radially sunken to the depth of a little less than half the diameter
of the inner ends of the spokes, which sinkings or recesses are inwardly terminated
by cross-directed and outwardly countersunk holes, wherethrough the spokes are
passed and threaded. That part of the face of the flauge inward of the laterally
or cross directed holes is set back from the outer part wherein the sinkings come.
Each end of the hub is fitted with a flanged cap or disc having half sinkings in
its face corresponding to and coincident with the half sinkings in the ends of the
hub. Each of the said caps has a collar of a height equal to the depth of the set
back inner part of the face of the head, and which keeps the cap central or in
position upon the head, so that when the opposed faces of the flange end of the
head and cap or disc come together, the spokes, which have been threaded
through the holes in the flanges, seat themselves in the sinkings and are there
clamped.
Thus, the spokes, whose inner ends are hook-shaped and hended, are (when the
cap is removed) passed from the inner side of the flange through the holes therein,
and then on the hooked ends coming up to the said flange, the said spokes are
raised from a horizontal to a vertical plane, which brings the shanks of the suid
inner ends partly to lie within the sinkings. The spokes being in this position,
then fit on the cap, when the sinkings on its opposed face take over the out-
standing halves of the spoke end, when by fixing the cap in its home position by
small screws or otherwise, the spokes are clamped between the cap and the flange
and fixedly secured in position, the thrust of the said spokes coming upon their
own hooked ends.
Figure 1 of the accompanying drawing represents a wheel hub provided with
means for securing spokes thereto constructed according to one form of my
invention. One end of the said hub is in elevation and the other and outer end is
in section.
Figure 2 represents an elevation of the outer end of the said hub.
Figure 3 is an inside elevation of the outer end cap separately and showing the
half sinkings on its face corresponding to those in the flange of the hub body.
Figure 4 is another elevation of the said hub, but with the end cap and some of
the spokes removed and showing the half sinkings in the flanged end for the
reception of the spoke ends.
Figure 5 represents one of the spoke ends separately.
The same letters of reference indicate corresponding parts in the several figures
of the drawing.

page_text: The hub a, consists of a waist or boly part al, with heads a³, a' at the inner and
outer ends of same. Each of these said heads have annular flanges a, circum-
ferentially recessed at a, and formed with a series of radiating half-round sinkings
or recesses a, adapted to receive the inner ends b', of the spokes h, which are hook-
shaped and headed at . The said spoke sinkings are inwardly terminated by
holes a', wherethrough the spokes are threaded into position and which are
outwardly countersunk to take the spoke heads.
Each of the ends a, a, of the said hub is fitted with a cap or flanged disc c,
formed on its presented inner face with radiating sinkings e¹ corresponding in
number and position to those on the outer face of the hub flanges and between
which sinkings a, c', the inner ends of the spokes lie. d is au aunular collar,
formed integral with or carried upon the inside face of the cap and which keeps
the said cap central or in position upon the head.
The cap or disc c, at the end a³, of the hub is slipped over the screwed axle, both
caps being secured to their respective hub flanges by small screws e, but to this
means of connection I do not limit myself.
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 :-
First. In hubs for the wheels of common road and other wheeled vehicles,
securing the spokes by clamping the inner ends of the same between or within
sinkings or nearly half-round sinkings formed in the opposed faces of hub end and
cap respectively, substantially as described and set forth.
Secondly. In hubs for the wheels of common road and other wheeled vehicles,
the combination with hook-ended and headed spokes, of hubs with segmental
spoke-clamping heads or ends constructed, arranged and applied, substantially as
described and set forth.
