Improvements in or connected with Wheel Tyres of Vehicles,
Locomotives, and such like.
I, WILLIAM HERBERT SEWELL, of Diamond, Coleraine, Ireland, General Produce
Merchant, do hereby declare the nature of this Invention to be as follows:-
This Invention has for its object to construct the wheels or tyres of vehicles,
locomotives, and such like whereby there will be a great saving of ground or rail
friction and consequently ease of propulsion and haulage.
In carrying my invention into practice, I formn the tyre or wheel rim with an
intermittent series of spherical, spheroidal, or cycloidal points. These points may be
either moulded into or on the rim or separately attached thereto. In the latter case
I provide the wheel rim with grooves, nests, or pockets in which these points are placed
and held in position by confinement at points of greatest diameter, or by any other
suitable means. The composition of these points may be metal, wood, vulcanite,
india-rubber, or any other suitable material or metal or combination of material or
metal, and are solid.
It will be obvious from my improvements that the revolution of wheel is made upon
a series of arcs or points placed apart, thereby obtaining the undoubted advantage
of freedom from skid or slip and great ease of movement. The wheel resting on
points requires much less power to move or start, and when moved the balance is
always in the line of motion.

Improvements in or connected with Wheel Tyres of Vehicles,
Locomotives, and such like.
I, WILLIAM HERBERT SEWELL, of Diamond, Coleraine, Ireland, General Produce
Merchant, 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, that is to say:-
My Invention has for its object to construct the wheels or tyres of vehicles,
locomotives, and such like whereby there will be a great saving of ground or rail
friction and consequently ease of propulsion and haulage, and is a further development
of my previous Patents Nos. 12257 A.D. 1894, and 17691 A.D. 1895.
In carrying my Invention into practice I form the tyre or wheel rim with an

either moulded into or on the rim or separately attached thereto. In the latter case
I provide the wheel rim with grooves, nests, or pockets in which these pc ats are
placed and held in position by confinement at points of greatest diameter, or by any
other suitable means. The composition of these points may be metal, wood, vulcanite,
india-rubber, or any other suitable material or metal or combination of material or
metal.
In order that my Invention may be properly understood and readily carried into
effect, I have hereunto appended one sheet of drawings on the several figures of which
corresponding parts are marked with the same letters of reference.

thereto.
cups, and showing
Figure 2 is a similar view of part of an ordinary road vehicle.
Figures 3, 4, 5, and 6 are views of different construction of
different methods of fixing the same to the rim of the wheel.
Figure 7 is an elevation of part of rim of different construction.
Referring to Figure 1 in which my improvements are applied to a locomotive, the
points A are of metal and forin an integral part of the rim B of wheel C, but they
may, where found advantageous or desirable, such for instance in waggons, tram-cars,
buses, or such like, be composed of rubber or any other suitable material, and be
bolted or otherwise fixed to the rim of the wheel. I provide a continuous guiding
flange D similar to that on existing locomotive wheels.
In applying my improvements to a horse or road vehicle as shown in Figure 2, the
sections A, which may be either spherical, spheroidal, cycloidal or hemispherical and
composed of solid rubber, or other noiseless or cushioning material, are placed in
cups D which are screwed or otherwise fixed to the rim B of the wheel C, as shown
in Figures 3 to 6. The sections A may be held or retained in position by means of
friction or by any of the methods shown in Figures 3 to 6.
In place of the cups as described and shown for the reception of the sections A, I
may make the rim B of the wheel of U-shaped tubular form with openings E in which
the sections A are placed as shown in Figure 7.
It will be obvious from my improvements that the revolution of wheel is made
upon a series of ares or points placed apart, thereby obtaining the undoubted
advantage of freedom from skid or slip and great ease of movement.
The wheel resting on points requires much less power to move or start, and when
moved the balance is always in the line of motion.
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:-
A wheel rim or tyre composed of, or built, and running on an intermittent or
divided series of solid metal, rubber or other points, suitable for locomotives, rail, or
other heavy road vehicular uses, substantially as described and illustrated on the
accompanying sheet of drawings.
