Improvements in and relating to the Wheels of Cycles and other
Vehicles.
PRESTON DAVIES of No. 12 Kempson Road Walham Green Fulham, in the
County of Middlesex Watch Maker do hereby declare the nature of this invention
to be as follows :-
In carrying out my invention I use a wheel constructed in the usual way with
suitable bearings, but of smaller diameter than the complete wheel is to be when
finished. I also use another wheel which is constructed the diameter of the finished
wheel, but in place of having a hubb, the spokes are attached to a ring of metal
preferably shaped in section, and the ring, of a diameter suitable to the
construction and size of the wheel. These two wheels of different diameters are
to form one complete wheel.
The spokes of the larger wheel passing clear of or through the rim, or through
slides or eyes attached to the rim of the smaller wheel whatever way be adopted,
the spokes of the larger wheel must be free to move in the direction of their
length. The ring of metal which forms the hubb of the larger diameter wheel is
to be inside the spokes, and encircling the hubb but in no way in contact or touching
the hubb of the wheel which is of the smaller diameter. Between the flanges of
the hubb and inside the spokes of the smaller wheel and the ring which forms the
hubb of the larger wheel I place an india rubber circular bag suitably covered to
prevent bursting and capable of being inflated with air in any known way the said
air chamber to form a cushion or buffer for the metal ring which forms the hubb of
the larger wheel.
To keep the rims of the two wheels at equal distances and to limit their amount
of play (if needed) I use india rubber or leather bands encircling both rims these
bands to go from the right side of one rim to the left side of the other, i.e. crossed
in between the two rims.

Improvements in and relating to the Wheels of Cycles and other
Vehicles.
I, PRESTON DAVIES, of 12 Kempson Road, Walham Green, Fulham, in the
County of Middlesex, Watchmaker, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement :—
This invention has reference to wheels for cycles and other vehicles and has for
its object means for the absorption of vibration.
In the annexed sheet of drawings
Fig. 1 is an elevation, and Fig. 2 is a section of a wheel made according to my
invention.
A, is an outer rim to which may be affixed any suitable tyre, a; B, are the
spokes connecting the rim, A, to a ring of metal, C, forming its hub and serving to
keep the rim, A, circular. D, is a rim of smaller diameter than the one, A, carried
in between the spokes B; E, are the spokes which connect the rim, D, with the
hub, F, of the wheel constructed in the usual way with suitable bearings. Between
the outer hub or ring, C, and the inner hub, F, I place a circular or other suitably

page_text: shaped bag, G, composed of india-rubber or other similar material covered with
canvas or its equivalent to prevent its undue expansion or bursting. This bag is
adapted to be inflated with air or filled with other elastic fluid through a valve or
equivalent device, and forms a buffer or cushion between the inner hub, F, of the
wheel of smaller diameter and the one, C, of the wheel of larger diameter. To
limit the amount of play between the two hubs and to prevent the one wheel being
partially revolved without the other, I attach the two rims, A, and, D, together by
means of india-rubber, leather, or like bands, H, at intervals around them. The
bands may be stretched over and rivetted or otherwise suitably secured to the
rims and are preferably 8 shaped in transverse section as shown in Figure 2, that
is to say, they go from the right side of one rim to the left side of the other, being
crossed between the two rims.
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 for cycles and other vehicles having an outer rim, A, bearing on to
and kept circular by a ring or outer hub, C, and an inner rim, D, bearing on to
an inner hub, F, and having between those bearing surfaces a bag, G, adapted to
be inflated or filled with air or other elastic fluid under pressure substantially as
set forth.
