Improvements in Wheels for Cycles, Vehicles, and the like for
Reducing Vibration.
SAMUEL WELLS, 14 Capel Road, Forest Gate Essex, Gentleman 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 :--
My invention has reference to an improved construction of the hub or nave of
the wheel, which is intended to obviate or lessen the vibration, from an uneven
road, that would be delivered to the axle.
Figure 1, is a section of the hub, shewing method of adjusting.
Figure 2, is an end view of the hub, with guard plate E off, shewing adjusting
cone, F.
Figure 3, is an end view with guard plate, E, on, shewing driving pin G.
Figures 4 & 5, of modification No. 3, are views of the hub shewing the metal
springs J, and adjusting cone F.
Figures 6 & 7, of modification No. 4, are views of the hub shewing the studs K,
with the coil springs L, and the bosses M, on the hub for holding the springs, with
their screwed caps N.
The first part of my improvement consists in constructing the hub in two
parts, one part through which the axle passes, I name the inner hub B, and the
other part which encircles the inner hub I call the outer hub A.
Between these two parts of the hub an elastic cushion of indiarubber or other
elastic material, D, surrounds the outer diameter of the inner hub, and another
elastic cushion of a like material is placed within the outer hub, A, and between
these two elastic cushions two adjustable circular wedge blocks F, of metal or any
suitable material, are fitted with their thin ends facing each other.
These wedge
blocks are drawn together by two or more screw bolts, H, passing through them,
to compress such elastic cushions to the pressure required by such wedge blocks F,
to keep the "outer hub" in its proper position.
The oblong holes in the guard plates E, admit of the outer hub moving
diametrically towards or from the inner hub.
The guard plates, E, are attached to the inner hub, and between these guard
plates the outer hub is free to move the required distance for flexibility from the
inner hub.
The oblong holes in the guard plates are made to receive one or more driving
pins, G, which are fixed to the "outer hub" so that motion to the "inner hub" is
also motion to the "outer hub."
To the outer hub one end of the spokes (when spokes are employed) are
attached, and the other ends are connected to the rim of the wheel by any of the
well known contrivances for such purposes.
2. The second part of my said improvement, is a modification of the first part herein
before described, and consists in using only one elastic material cushion, such
cushion being placed between the inner hub and the circular wedge blocks, or
between the circular wedge blocks and the outer hub. In this arrangement each
of the circular wedge blocks are divided into three or more sections diametrically,
with one or more screw bolts passing through similar sections to draw them
together, to compress the elastic cushion as required in the same manner as herein
before described.

page_text: 3. The third part is a modification of the foregoing Fig. 4 & 5 and consists in
constructing the elastic cushions of metal springs J, each in the form of a concave
ring of the desired width, and thickness; the edges of these spring rings have a
continuous form of the letter V for about one third of their width by notches in
them, the concavity of such rings J, providing for the distance required to give
sufficient spring action.
4. The fourth part of my said in provements, is a modification of the third part
hereof, and consists in constructing on the "outer hub" on the longitudinal centre
line thereof, three or more sockets or bosses M protruding outwards, and having
caps N on their outer ends, and in each of these sockets one or more spiral
or coil springs L are placed. One end of a stud K is fitted to pass through
the spiral or coil springs L and through the cap N on the outer end of the
socket.
At a short distance from the other end of the stud that is within the "outer
hub," there is a collar to act on the spiral or coil springs. This end of the stud
has a head formed on it that fits on the circular wedge blocks F so that when such
wedge blocks are drawn together or towards each other, the desired pressure is
delivered to the spiral or coil springs L on which the studs K act to carry the load
with the required flexibility.
5. When no spokes are employed in the wheel, then the "outer hub" is also the
rim of the wheel, if of very small diameter, on which a wood or metal tyre is fixed
as desired.
In this form the wheel is applicable as a roller, when the load is carried on the
axle.
6. I have described the cushions & circular wedge blocks with plain superficies
but by preference they are grooved on the superficies that act on each other. The
circular wedge blocks being grooved longitudinally such grooves being at equal
distances apart, so that half the area of their circumferences are grooved to a
shallow depth. The india-rubber or elastic material cushions, are also grooved on
their circumferences, facing each other, at equal distances apart.
7. By these arrangements the wheel, except the "inner hub" thereof, is free to
move diametrically towards and from the "inner hub," the distance provided for
by the elastic cushions therein.
The motion thereof is adjustable to suit
of absorbing or lessening the vibration
delivered to the axle.
the load to be carried, for the purpose
from an uneven road, that would be
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 :-
The construction of hubs of wheels for cycles, and other vehicles with guard
plates to allow lateral motion, held to the hub by one or more screws & rubber or
metal springs with adjustable cones to regulate their tension to suit the load on
wheels.
