PROVISIONAL SPECIFICATION.
Wheels for Road Vehicles, and Fittings therefor.
JAMES DAKERS 7 Union Wynd and 24 Union Row in the County of
Aberdeen North Britain, Coach Builder, do hereby declare the nature of this
invention to be as follows :-
This invention relates to certain improvements in wheels for road vehicles and
in fittings for the same which are designed to render such more simple in
constructions more durable and more easily repaired than as hitherto constructed
and fitted.
In carrying this invention into practice I make wheels apart from the ordinary
wood or iron nave I make a band or hoop of larger dimensions than the ordinary
wood or iron nave of iron or steel or any suitable metal I form a bearing flange
round each end or side of band or hoop. I raise and make mortices on the outside
surface to hold the ends of spokes of wheel no shoulders being required the ends
of spokes bearing on hand or hoop at the bottom of the mortices. I put a small
bolt pin or screw through each mortice to hold spokes fast in the mortice. On
the inner circle of band or hoop I make grooves or raise small studs to hold an
india rubber band from turning round. In place of the ordinary wood or part
iron naves I make a band or hoop of iron or steel the inner ends I make of
larger dimensions than the outer end or front of nave. I raise or make a flange
or shoulder round the outside surface I also cut or run a screw thread round
bands in front of shoulder I have formed. I make a loose flange of iron or steel
I cut or run a thread round the inside circle and fit on to screws that I have
formed on band the flange forming a box or groove all round the band. I raise
grooves or studs all round bottom of box to hold rubber band from turning round
I make a rubber band either pneumatic or otherwise I make grooves or raise
studs on outside circle and inside circle to keep the band from turning round.
I fix an air valve to the band the valve passing up through the band or hoop that
holds the spokes. I take off loose flange which forms the one side of box I put
on the wheel and rubber band I screw on flange which locks the wheel into the
box then I fill the band with air for to resist dead shocks and reduce vibration.
The second part of my invention is the band I make in place of the wood nave
I fill inside circle with wood to hold the axle bush and wedges for holding and
faring up the wheel.
I put one or more bolts through the flange or shoulder I have formed on the
outside surface of band or hoop to fasten on axle that requires bolts through
the nave.
The third part of my invention is in place of fastening my axle bush with
wood and wedges I make the wood I fill in to the inside of band or hoop shorter
than the axle bush the wood forming a shoulder all round the bush.
I cut or run a thread round iron band in front of shoulder I have formed with
the wood I make a loose flange of steel or iron I cut or run a thread on the outside
circle and fit on screw I have made on band this forming a box all round inside
of bush.
I make an india rubber band which is honeycombed out I fit into the box
I have formed at each ends of the hoop or band I pass the axle bush through both
bands when the loose flanges are screwed up. The rubber bands are pressed

page_text: tightly round the bush and holds it firm in the nave for to relieve dead shocks and
to reduce vibration. This part of my invention can be wrought without the
outside rubber band I fill with air and have the mortices and spokes fixed in the
same way as I have already described on the outside hoop or band.

JAMES DAKERS 7 Union Wynd and 24 Union Row in the County of Aberdeen
North Britain Coach Builder, 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 relates to certain improvements in wheels for road vehicles and
in fittings for the same, which are designed to render such more simple in con-
struction, more durable, and more easily repaired than those hitherto constructed
and fitted.
In carrying this invention into practice I make the wheels apart from the
ordinary wood or iron nave, and I make a band or hoop of larger dimensions than
the ordinary wood or iron nave of iron or steel or any suitable metal.
I form a bearing flange round each end or side of this band or hoop, and I so
shape the outside of the latter, as to form mortices for the reception of the inner
ends of the spokes of the wheel, and I fasten these securely in position by passing
a small bolt, pin, or screw through the flanges and the spoke. Between the band
and the " nave proper is a ring of india-rubber.
"
In order that my invention may be fully understood I illustrate it by means of a
sheet of drawings in which :-
Fig. 1 is a section taken through the axis of a wheel nave according to my
invention.
Fig. 2 is a section (on line 1, 1, of Fig. 1) of a portion of the same.
Fig. 3 is a section of a modified form of nave.
Fig. 4 is an elevation of a rubber band as used.
Fig. 5 is a section through the axis of a bicycle wheel hub, shewing a different
mode of fitting on each side according to my invention.
In Figs. 1 and 2 an axle-bush or box i is bored through its length to receive an
axle of any suitable description, upon which it rotates. Outside this axle-bush or
"
box is a hoop or band e which forms the " nave proper and the axle-bush or box i
is fixed firmly inside it by driving it into a wood filling n, which fits tightly inside e
and outside. The nave and the whole wheel are held securely upon the axle by
bolts d or by any other suitable and convenient means such as are ordinarily
employed for the purpose. The hoop or band e has one flange g formed integrally
with its outside, and a second g which is screwed upon it.
The distance between
these two flanges when in position, is such that a ring f of steel or other metal can
move freely in it, and this ring f has two flanges c formed upon its outer surface,
and the space thus enclosed is divided by partitions into mortices of a shape and
size suitable to receive the ends p of the spokes of the wheel, each of these spokes
being held in position by a pin X passing through it and through the flanges c.
The interior of the ring has formed upon it studs y, and similar studs y are
formed upon the middle portion of the exterior of the hoop or band e.
Between the flanges 9 and g¹, and the hoop or band e and ring f is enclosed an
annular hollow ring of rubber a the interior forming an air chamber 9 into which
air can be pumped up to any required pressure, and retained therein by an air
valve b. The ring fand the hoop or band e are prevented from rotating the one

page_text: without the other or without the rubber ring a, by reason of the studs y or
equivalent grooves which either press into the rubber or receive parts of the
same.
When the rim of a wheel according to my invention is running over a road,.
any shocks it may receive will not be felt at the axle, but will be intercepted
and taken up by the rubber and air cushion a, thus practically forming a
pneumatic hub.
In Fig. 3 is shewn a modification of my invention in which the mortices m for
the reception of the inner ends of the spokes are between the flanges c which
form an integral part of the hoop or band e. In this case the axle-bush or box i
is not driven firmly into the wood n (as is the case in the device shewn in Fig. 1).
but fits loosely therein, and at the ends of the wood n are two india-rubber rings a
which are forced into their places by the internal flanges 9 which screw into
the band or bush e. These bands a take up and intercept any shocks.
instead of conveying them to the axle-bush or box i, serving in fact the
same purpose as the pneumatic ring a shewn in Figs. 1 and 2. The india-rubber
or other resilient band is preferably formed as shewn in Fig. 4 where it is.
perforated or honeycombed.
In Fig. 5' my invention is shewn as applied to a cycle wheel; i is the bush or
hub which has two flanges g² projecting from it, the space between being covered
in by a plate h upon which the interior of a rubber, air, or pneumatic ring a fits.
The exterior of this air ring fits against an enclosing ring c which has one internal
fixed flange g and one removable flange g¹. The spokes p of the wheel are
screwed into the ring c and the two flanges g and g' are so fitted as to slide freely
on the outside of the flanges 92 thus causing the pneumatic ring a to act as a
cushion and take up any shocks instead of communicating them to the axle and
vehicle.
On the right hand side of the bush or hub i the wheel is attached in a somewhat.
different manner, but the principle remains the same the ring c having interposed
between it and the hub i, a pneumatic or air ring a.
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. Forming a wheel nave in two sections or parts, having an inner nave e and
an outer band f, and interposing between the two a rubber air band or ring which
is held in position by flanges in the manner and for the purpose substantially as.
described and shewn.
2. A. wheel for road vehicles in which the rim and spokes are elastically
connected with the axle-bush substantially as shewn and described with reference.
to Figs. 1 and 2.
3. A wheel for road vehicles in which the rim and spokes are elastically
connected with the axle-bush substantially as shewn and described with reference.
to Fig. 3.
4. A wheel for cycles and other road vehicles, in which the rim and spokes are
elastically connected with the axle-bush substantially as shewn and described with
reference to Fig. 5.
5. In a wheel for road vehicles the combination with a rim and spokes of the
axle bush i, the wood filling n, the hoop or band e having flanges 9 and gl, the
elastic air ring a, and the ring f having mortices for the reception of the inner-
ends of the spokes p, substantially as shewn and described.
