Northampton, Machine Agent, do hereby declare the nature of this invention to
be as follows:-
This invention for improvements in wheels of road vehicles relates to that
class of wheel in which means are provided in the hub for forcing the spokes
outwards towards the felloe; and has for its objects to provide an improved
arrangement of mechanism for forcing the spokes outwards towards the felloe,
improved arrangements for securing the wheel on the axle and for oiling the axle,
and an improved tire.
In a wheel constructed according to this invention the inner end of each spoke is
received in a loose shoe situated within the nave and having its inner surface
forming a portion of a cone and a corresponding cone is fixed axially on the axle
box so that it can be forced along the said box to force the shoe and with it the
spoke outwards. The inner ends of the shoes bear against an internal flange in the

1 HARREY MOORE, of High Street, Wellingborough in the County of
Northampton, Machine Agent, 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 for improvements in wheels of road vehicles relates to that class
of wheel in which means are provided in the hub for forcing the spokes outwards
towards the felloe; and has for its objects to provide an improved arrangement of
mechanisin for forcing the spokes outwards towards the felloe, and improved
arrangements for securing the wheel on the axle and for oiling the axle.
In a wheel constructed according to this invention the inner end of each spoke is
received in a loose shoe situated within the nave and having its inner surface
forming a portion of a cone and a corresponding cone is fitted axially on the axle
box so that it can be forced along the said box to force the shoe and with it the
spoke outwards. The inner ends of the shoes bear against an internal flange in the
nave so as to prevent them being forced in with the expanding cone or their inner
ends project beyond the spokes and slide in radial grooves in the said flange. The
shoes are so shaped that in their innermost position they form together a full and
complete ring coned interiorly and provided on its exterior with recesses to receive
the ends of the spokes. The outer end of the cone is secured by radial arms to a
ring fitting within the nave. The cone is screwed on the axle box and is operated
by means of a head having a central recess to pass over the axle box, slots into
which the radial arms are received, and a hole by which it can be rotated by a
crow or other bar. The nave is formed with an internal recessed flange and the
axle box provided with a corresponding external flange is inserted from the back of
the nave, its flange taking into the recess in the internal flange of the nave. The
axle box is prevented from rotating in the nave by a lug or other suitable means.
The inner part of the tire is channel shaped in cross section preferably with the
sides inclined outwards and is rolled or cast endless without weld or joint of any
kind. The outer part may be formed to receive a rubber or other tire.
The axle box is secured on the axle by means of studs or bolts screwed or
otherwise fixed in the inner flange of the axle box and to which is secured by nuts
the back plate and the leather washer bearing on the inside of the collar on
the axle.
In a modification the nave of the wheel is secured on the axle by means of an oil
box placed on the inside of the collar on the axle and screwing into the nave, the
whole being further secured by a lock nut screwing on the axle and bearing
against the inner end of the oil box. The oil box and lock nut are placed on
the axle before the two parts are welded together. The bearing surface of the
axle box is formed with right and left spiral grooves so as to thoroughly distribute
the oil.
In the accompanying two sheets of drawings
Fig. 1 is a longitudinal section of a hub of a wheel constructed according to this
invention.
Fig. 2 is a similar view to Fig. 1 showing the parts in the position they occupy
before the spokes are expanded or forced outwards.
Figs. 3 and 4 are cross sections corresponding respectively to Figs. 1 and 2.

of securing the axle box on the axle.
Figs. 6 and 7 are respectively side and end elevations of the cone for forcing
the wedges outwards against the ends of the spokes.

page_text: Figs. 11, 12, and 13, and Figs. 14, 15 and 16, are similar views to Figs. 8, 9
and 10 showing two slight modifications of the wedges.
Figs. 17 and 18 are respectively side and end elevations of a key for operating
the expanding cone.
The nave a of the wheel is provided with the usual mortices 6 to receive the
ends of the spokes c and with an internal rib d at the back of the mortices 6 and
with an internal recessed flange e. The axle box f is provided with a flange g
corresponding to and taking into the recess of the flange e of the nave and is
prevented from rotating in the nave by the pin h. The axle i is formed with a
shoulder and with a collar m; and a cylindrical box n, leather washer o and lock
nut p, are inserted on the axle at the back of the collar before the two parts are
welded together. The box n which also serves as an oil box screws into the end
of the nave and draws the end of the axle box against the collar m so that the
whole is firmly secured on the axle and is locked by means of the nut p, the thread
on the axle being tapered so that the nut is perfectly tight when in position and
being left handed. The inner end of each spoke e is formed with a tenon" which
is received in a separate and loose shoe s situated within the nave a and having
its inner surface forming a portion of a cone. The loose shoes s corresponding
thus in number to the number of the spokes are inserted into the nave with their
inner ends bearing against the rib d and so that the recess in each shoe is opposite
a mortice in the nave. In this position the shoes together form a full and
complete ring coned interiorly and provided on its exterior with recesses opposite
to the mortices b. A male cone t corresponding to the cone of the shoes is screwed
on the axle and is provided with a head consisting of the ring u fitting into the
end of the nave and secured to the cone by radial arms v, the whole preferably
being formed in one piece. The cone t is operated by means of the head having
a central recess y to pass over the end of the axle box, slots a a into which the
radial arms are received and a hole a by which it can be rotated by a crow or
other bar. The shoes are forced outwards to expand the spokes by screwing
the cone t along the axle when the ring of shoes s opens out, each shoe being
forced outwards and forcing its spoke towards the felloe. The rib d forms a stop
for the shoes and prevents them being moved further inwards with the male
cone t. The cone is secured by a lock nut a c screwing on the end of the axle
Preferably the cone t has a right handed thread and the lock nut a c a left
handed thread.
box.
In the modified shoe shown in Figs. 11, 12 and 13 the shoe is formed with a
tail a d sliding in a slot a e in the rib and Figs. 14, 15 and 16 show a modified
shape of shoe.
In the modified arrangements for securing the wheel on the axle shown in Fig.
the Bange on the inner end of the axle box f is provided with studs a for
bolts ag fixed therein and the whole is secured on the axle by means of the
nuts a hand washer plate a k which is divided across its centre to enable it to be
put in position or it may be placed on the axle before the two ends are welded
together. o is a leather washer. In Fig. 1a is an oil receiver box and al forms
the end of the hub and protects the box a i.
The axle box is provided with a right hand spiral groove a m and a left hand
spiral groove a n so as to thoroughly distribute the oil.
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. In a wheel the combination with the nave, the spokes passing through mortices
in the nave and the axle box, of a series of wedge shaped shoes adapted to fit
firmly on the ends of the spokes so as to be guided radially thereby and to be
prevented from longitudinal or sideways motion and of means for forcing the said
shoes outwards radially, substantially as set forth.
2. In a wheel, the combination with the nave, the spokes passing through mortices

outwards, and of an internal rib integral with the nave and forming an axial stop
for the shoes, substantially as set forth.
5. In a wheel the combination with the axle and a collar on the axle, of an axle
box having an external flange, a nave having an internal flange adapted to bear on
the front of the axle box flange, of a box adapted to bear against the back of
and be retained by the collar and to be secured to the nave substantially as set
forth.
6. In a wheel the combination with spokes radially extensible from the hub to
the felloes and the collar on the axle of a washer plate bearing on the back of the
collar and of screwed bolts or studs fixed in the back end of the hub and adapted
