Improvements in and relating to Wheels of Road Vehicles.
I HARREY MOORE of High Street, Wellingborough in the County of
Northampton, Machine Agent do hereby declare the nature of this invention to
be as follows:-
My invention relates to improvements in the construction of wheels whereby the
spokes may be extended between the hub and the felloe in order to obtain the
necessary rigidity in the wheel; to the means of distributing oil upon the axle
automatically by the rotation of the wheel and to the special form of tire employed
for the wheel.
I make the axle box with a flange having a number of undercut radial grooves
therein corresponding with the number of spokes to be put in the wheel. In these
radial grooves, wedge shaped bars are secured capable of moving therein so as to
close towards the centre of the axle box until they all meet laterally forming a
cylinder with a conical bore therein. These wedge shaped bars together with the
axle box are fitted into the nave of the wheel so as to bring one of these bars to
face each of the mòrtices of the nave in which the spokes are fitted. Thus the
wedge shaped bars form bases upon which the spokes rest within the nave of
the wheel and as they are movable in the radial grooves they may be expanded
by means of a cone screwed on to the axle-box within the nave so as to extend
the spokes from the nave towards the felloe and thus put the required strain
upon the wheel to obtain the required rigidity. The cone being screwed upon the
axle-box by means of a right hand screw thread thereon, may be securely retained
by a following nut engaging with a left handed screw made upon that part of
the axle-box which projects beyond the cone. The axle-box has at its rear end
a cylindrical box made for receiving a store of oil admitted through the nave of
the wheel at an orifice closed by a screw. This orifice in the nave of the wheel
may be made to correspond with a passage through a tube fixed in the cylindrical
oil box and projecting therein radially as nearly as possible to the axle which
passes centrally through the cylindrical oil box and the axle-box. This tubular
projection serves to fill the cylindrical oil box to about the level of the central
opening therein through which the axle passes and acts as a dipping peg passing
once through the body of oil contained in the cylindrical oil box at each revolution
of the wheel and depositing upon the axle drops of oil which drain from this
dipping peg as it passes out from the oil in completing each revolution of the wheel.
The oil thus deposited upon the axle finds its way along by suitable oil channels
formed in the axle or the axle-box and may drip from the axle at the outer side
of the nave of the wheel into an internally Hanged nut screwed on to the nave of
the wheel to form a reservoir for such waste oil to be collected in. Upon the axle
I provide a dust proof case which encloses the cylindrical oil box and projects into
an annular groove made endwise in the nave of the wheel.
The axle-box may be retained upon the axle by the use of left and right handed
nuts and cottars in the usual way.
I make the tire preferably with an outwardly curved flange at each side pro-
jecting towards the centre of the wheel. The extension of the spokes thus tends
to force the felloe into the tapered channel which the flanged tire represents and so
secures the tire upon the wheel without spikes or bolts by which ordinary tires are
secured to the felloes of wheels.

Improvements in and relating to Wheels of Road Vehicles.
I 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 relates to improvements in the construction of wheels in which
the spokes are extended between the hub and the felloe in order to obtain the
necessary rigidity in the wheel; to the means of distributing oil upon the axle
automatically by the rotation of the wheel and to the special form of tire employed
for the wheel.
I make and construct the wheel as shown in the accompanying drawings in
which
Figure 1 is a front elevation of my improved wheel.
Figure 2 is a cross section through the felloe showing the form of the iron tire.
Figure 3 is a cross section through the felloe showing a modification in form of
the iron rim suitable for receiving an india rubber tire.
Figure 4 is a sectional view of the hub the spoke extending mechanism being
shown in its contracted form.
Figure 5 is a section taken at the line a b in Figure 4 showing the application of
the spoke extending wedges to the spokes.
Figure 6 is an elevation of the radial mortice plate.
Figure 7 is a plan of Figure 6.
Figure 8 is a side view and Figure 9 is a plan of one of the spoke extending
wedges.
Figure 10 is a sectional view of the hub the spoke extending mechanism being
shown in its expanded form.
Figure 11 is a section taken at the line cd in Figure 10 showing the expansion
of the spoke extending mechanism.
Figure 12 is an elevation and Figure 13 a plan of the cone employed for the
spoke extending mechanism.
Figure 14 is a sectional view of a modified form of hub employing two cones for
the spoke extending mechanism which in this figure is shown in its contracted form.
Figure 15 is a section taken upon the line e f in Figure 14.
Figure 16 is a sectional view similar to Figure 14 the spoke extending mechanism
being shown in its expanded form and the oil-box and oil-cap applied thereto.
Figure 17 is a front elevation of the modified form of radial mortice plate as
adapted to the spoke extending mechanism shown in Figures 14 and 16.
Figure 18 is a side elevation of Figure 17.
Upon the axle-box and secured thereto by the pins à I provide a radial mortice
plate A having a number of undercut radial grooves corresponding with the number
of spokes to be put in the wheel. In these radial grooves wedge shaped bars B
are secured capable of moving therein so as to close towards the centre of the
axle-box C until they all meet laterally forming a cylinder having a conical bore.
These wedge shaped bars B together with the axle-box C are fitted into the nave
of the wheel so as to bring one of these bars B to face each of the mortices D of
the nave in which the spokes are fitted. Thus the wedge shaped bars B form bases
upon which the spokes E rest within the nave of the wheel and as they are movable
in the radial grooves of the radial mortice plate A. they may be expanded by means
of a cone F screwed upon the axle-box C within the nave of the wheel so as to
extend the spokes from the nave towards the felloe and thus put the required strain
upon the wheel to obtain the required rigidity. The cone F being screwed upon
the axle-box C by means of a right hand screw thread formed thereon may be
securely retained by a following nut G engaging with a left hand screw thread G¹
formed upon that part of the axle-box C which projects beyond the cone F.

page_text: The axle-box C has at its rear end a cylindrical box H secured thereto by the
screws made for receiving a store of oil admitted through an orifice in a dust
proof case K closed by a screw L. This orifice may be made to correspond with a
passage a through a tube 6 fixed in the oil-box H and projecting therein radially
as nearly as possible to the axle M which passes centrally to the oil-box H and the
axle-box C. The tubular projection serves for filling the oil-box H to about the
level of the central opening therein, through which the axle M passes, and acts as
a dipping peg passing once through the body of oil contained in the oil-box H at
each, revolution of the wheel and depositing upon the axle M drops of oil which
drain from the dipping peg as it passes out from the oil in completing each
revolution of the wheel. The oil thus deposited upon the axle finds its way along
by suitable oil channels cut upon the axle M or within the axle-box C and may drip
from the axle M at the outer extremity of the nave of the wheel into a hollow
nut N screwed on to the cone F as shown in Figures 4 and 10 or into the axle-
box C as shown in Figure 16. The hollow nut N forms a reservoir in which the
oil after lubricating the axle is collected.
In order to protect the oil-box H from admission of dust I provide the dust proof
case K secured by the screws c c to the axle M and extending under cover of the
nave of the wheel as shown in Figure 16 or in an annular groove made endwise in
the nave of the wheel as shown in Figures 4 and 10. The axle-box C may be
retained upon the axle M by left and right handed nuts and a cottar in the
usual way.
I make the tire preferably with a downwardly inclined flange gat each side
projecting towards the centre of the wheel. The extension of the spokes thus
tends to force the felloe h into the tapering channel which the flanged tire represents
and so secures the tire upon the wheel without spikes or bolts by which ordinary
tires are secured to the felloes of wheels. In case of employing an india rubber
tire I make the rim in the form shown in Figure 3 to receive the india rubber tire k.
In the case of wheels intended for heavy vehicles I make a modification in the
spoke extending mechanism to provide for expanding the wedge shaped bars by two
cones instead of one. The modifications are shown in Figures 14, 15, 16, 17 and 18.
The axle-box C is grooved at its centre to receive the mortice plate P which is
cut in two halves for placing it in the recess or groove Q. One of the cones F¹
has a left hand screw thread and the other F" has a right hand screw thread the
axle-box C being correspondingly threaded in a left hand direction at one side of
the groove or recess Q and in a right hand direction at the other side. These
cones F1 and F" are guided in the nave of the wheel by projections forming
feathers to slide in grooves m made in the nave so that the cones may be made to
approach to or recede from each other without rotating by rotating the axle-box C
by means of a suitable spanner applied at n. The mortice plate P receives the
tongues R dependent from the double ended wedge shaped bars B to keep these
bars in position to bear evenly upon the spokes E which rest upon them to be
extended thereby in accordance with the pressure brought to bear by entering the
cones. In this case the oil-box H is applied by the screws ff after expanding
the spoke extending mechanism which is securely fastened by the lock nuts p and pl
then the wheel is put upon the axle M upon which the dust proof case has been
previously fixed by the screws c c. The axle-box C abuts against the ring or
collar S to relieve the end thrust of the wheel from the oil-box H.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a wheel having cone mechanism within the hub to force the spokes out-
wardly from the hub in radial directions, the combination of a cone or cones a
screw threaded axle-box engaging therewith, wedge shaped bars and a radial
mortice plate substantially as and for the purposes described.
2. The combination of an oil-box and a tubular dipping peg for filling oil into

page_text: the said oil-box and distributing the same upon the axle of a wheel when the wheel
is rotated substantially as described.
3. The combination of a wheel having spokes extensible radially from the hub
to the felloe and a doubly flanged tire into which the felloe is expanded to obtain
the required rigidity of the wheel substantially as described.
