arms 25 to hold them in yielding contact
with the rods 11, due to the fact that said
coil springs have their terminals. resting
against the inner surface of the arms 3 and
5 the flanges 27 of the arms 25, respectively.
Guard arms 25' are secured to the inner
faces of the spoke arms 3 and extend at their
inner ends between the rod 11 and the ends
of the arms 25 which are movable upon the
10 bar 16. Thus the liability of said arms con-
tacting with the springs 21 and 22 is effec-
tually prevented.
The outer rim 8 is provided preferably
with an integral flange 30, said flanoe be-
15 ing adapted to extend inwardly a sucient
distance to cover the operative parts of the
spokes 2, and may be so shaped as to fit
snugly against the spokes to prevent access
of foreign matter to the same. The rim S
20 is further provided with a series of ears 31,
to which is bolted the outer edge of a cover
32, said cover being for the purpose of pro-
tecting the mechanism mounted within the
spokes 2, from foreign matter, and in a
25 manner similar to that of the flange 30.
The inner face of the flange 30 and cover
32 may be provided with a. packing of felt
or like material to more effectually prevent
the access of dust and grit to the interior
so of the wheel.
From this construction it will be seen that
the weight of the vehicle is equally dis-
tributed upon the coil springs 21 and 22,
during the rotation of the wheel, and that
35 the shock incident to the starting of the ve-
hicle is absorbed by the coil springs 29
which are connected to the arms 25. This
construction in no way interferes with the
reciprocation of the rod 11, said rod being
40 permitted to slide upon the bar 16 slightly
when the vehicle is started. By adjusting
the nuts 20 the tension of the springs may
be regulated as desired.
Having thus described the invention, I
45 claim:
1. In a wheel, the combination with a hub,
of inner and outer rims, spokes radiating
from said hub, said spokes being formed
from tubular metal and provided at their
'50 outer ends with a pair of diverging arms
the outer ends of which are secured to the
inner rim, slots formed in the same rim, and
rods pivotally connected at their outer ends
to the outer rim and positioned between the
55 diverging arms, said rods being provided
with longitudinal slots, bars supported by
said arms and passed through saidslots, and
coil springs surrounding said rods and hav-
ing their opposing terminals resting upon
60 said bars.
2. In a spring wheel, the combination of
a hub, having spokes radiating therefrom,
inner and outer rims, the inner rim being
provided with a series of slots spaced an
65 equal distance apart, rods pivotally connect-ed at their outer ends to the _outer .rim and
adapted to pass through the slots in the in-
ner rim, said rods -being provided with a
longitudinal slot, bars supported by the
spokes and passing through the slots formed70
in- the rods, coil springs surrounding said
rods and having their opposing terminals
resting against said bars, a pair of arms
supported by said bars, said arms having
their outer ends held in yielding contact
with the said rods.
3. In a spring wheel the combination
with a hub having spokes radiating there-
from, of inner and outer rims, the inner rim
being provided with slots, said spokes being 80
formed with diverging arms, blocks formed
upon the inner surface of the outer rim, rods
pivotally connected at their outer ends to
said blocks and passing through the slots, in
the- inner rim and between the diverging 85
arms of the spokes, longitudinal slots formed
in said rods, a bar supported by said arms
and passing through said slots, coil springs
surrounding said rods and having their -op-
posing terminals resting against opposite 90
sides of said bars, a pair of arms supported
by said bars, pins pivotally connected to said
arms, openings formed in the upper -ends of
the diverging arms, of the spokes, said pins
being slidably mounted in said-openings,coil 95
springs surrounding said pins and adapted
to hold -said arms in yielding contact with
the rods, and means for regulating the ten-
sion of the springs which surround said
rods. 100
4. In a spring wheel, the combination
with a hub, of inner and outer rims, spokes
radiating from the hub, said spokes having
diverging arms formed on 'their outer ends
rigidly secured to said inner rim, said rim 105
having slots formed therein between the
spoke arms, rods pivotally connected to the
outer rim and positioned between said di-
verging arms, means connecting said diverg-
ing arms to guide the rods, coiled springs 110
arranged upon said rods, and plates ar-
ranged on said rods and adapted to be en-
gaged by the spokes in their outward move-
ment with relation to the rods to compress
one of said springs. 115
5. In a wheel, the combination with a hub,
of inner and outer rims, spokes radiating
from said hub and provided at their outer
ends with diverging arms rigidly secured to
the inner rim, slots formed in said rim be- 120
tween the arms, rods.pivotally connected to
the outer rim and extending through said
slots and positioned between the spoke arms,
said rods being provided with longitudinal
slots, guide bars connecting the diverging 125
arms and extending through said slots in
the rods, springs arranged on each of the
rods on opposite sides of the guide bar, a
plate on the inner end of the rod, a nut
threaded on the rod to normally hold said iso2
