IN THE CONSTRUCTION OF WHEELS FOR VEHICLES
"
"IMPROVEMENTS
The object of my Invention is to increase the strength and durability of wheels
for vehicles.
In wheels as ordinarily constructed the felloes or sections which together form
the rim, are pierced or bored with holes, passing right through them, to receive
the outer ends, tongues or tenons of the spokes. These holes considerably
diminish the strength of the felloes, and the holes or recesses formed in their
ends to receive the dowels (by means of which the different felloes or sections
are joined together to form the complete rim) still further weaken the same.
The junctions of the abutting felloes or sections are also left unsupported thus
producing a further defect in the finished wheel.
My Invention consists in arranging some of the spokes so that their outer ends,
tongues or tenons are situated opposite the abutting ends or junction of each two
adjacent felloes; whilst the outer ends, tongues or tenons of the other or inter-
mediate spokes come opposite the centre of each felloe.
The extreme outer end, tongue or tenon of each of the spokes opposite the
junctions of the felloes is preferably tapered and fits into a correspondingly tapered
metallic socket (preferably of malleable cast iron). The object of making the
sockets and the tongues or tenons of the spokes tapering is to ensure the more
perfect fitting of the two, and to cause the weight resting on the wheels to tend to
force the two more closely together. But, in some cases, if found desirable the
sockets and the tongues or tenons of the spokes may be left straight.
The socket forms part of, or is secured to plates shaped so as to cover the joints
of the felloes on the under side, and also the back and front of the same, so that when
the tyre is in position on the rim the joints of the felloes are completely enclosed
on all sides. Bolts or rivets pass through the back and front plates and the felloe
in one direction, and others through the under plate, the felloe, and the tyre in a
direction at right angles to the former, the heads of the bolts or rivets being
preferably countersunk into the plates and tyre.

page_text: The part of the felloe over which the plates fit will preferably be made to taper
from the tyre downwards, and the plates will be correspondingly tapered to fit the
same, but they may be left straight if desired.
The outer ends, tongues or tenons of the intermediate spokes may also be
inserted into similar sockets with plates fitting over the felloes and secured by
bolts or rivets as described. Or the tongues or tenons of these latter spokes may
fit into holes formed in the under side of the felloe, but passing only partly through
the same.
These holes and the tongues or tenons of the spokes may be either
formed straight or tapering.
The wheel will thus be formed with entire felloes, that is, with felloes having
no holes for spokes passing right through them as in ordinary wheels, and the
joints of the felloes being entirely enclosed by the plates and tyre will not
require the use of dowels, so that the recesses or holes usually formed in the
abutting ends of the felloes to receive them will be abolished, and the whole of
the wheel will be greatly increased in strength and durability.
If necessary the outer side or sole of the felloes may have a small piece of iron
hooping inserted at the joints in place of the ordinary dowels.
In order to give the wheel when completed a neater or more finished appearance
the tongues, tenons or extreme outer ends of the spokes may be recessed so that the
outer surface of the socket will come flush with the surface of the spokes, and the
felloes may be similarly recessed so as to bring the outer surfaces of the plates flush
with them.
