extension 17 and to one arm of a bell crank
lever 22 fulcrumed upon a bolt 23 which is
secured to the disks 4 at a point removed
from the middle disk 10. The long arms of
5 the bell crank levers extend between the
flanges 3 and through the slots 2, the outer
ends of these arms being provided with op-
positely extending studs 24 projecting into
the ends of tapered coiled springs 25 seated
1o within the tubular rim 1. These studs pro-
ject into the small ends of the springs and
the large ends of said springs abut against
spacing blocks 26 which are secured within
the rim 1 by means of transversely extend-
15 ing bolts 27 or the like, there being studs
28 extending from the blocks and into the
adjacent convolutions of the springs 25.
Thus it will be seen that between every two
blocks 26 is a pair of oppositely disposed
20 tapered coiled springs, the long arm of each
bell crank lever 22 Teing extended between
the springs of each pair. All of the springs
are of the same strength and under ordi-
nary conditions bear with equal pressure
25 against both sides of the lever arm extend-
ing therebetween.
Rings 29 are secured to the rim 1 at dia-
metrically opposed points, the outer edges
of these rings being concaved transversely
30 to form seats 30 adapted to receive the side
portions of a tire 31 of rubber or the like.
These side portions of the tire are preferably
in the form of annular flanges, as indicated
at 32, each flange being adapted to be en-
35 gaged by a wire 33 which extends around
the wheel and is secured at one end to the
ring 29, as shown at 34 while its other end
is attached to a disk 35 journaled within
a recess 36 in one side of the ring 29. A
40 ratchet wheel 37 is secured to and rotates
with the disk 35 and is normally engaged
by a spring pressed pawl 38 whereby rota-
tion of the disk and ratchet wheel in one
direction is prevented. An angular stud or
45 projection 39 extends from the center of the
wheel 37 and is adapted to be engaged by a
crank, not shown, whereby the ratchet wheel
37 and disk 35 can be rotated so as to wind
one end portion of wire 33 upon the disk.
50 It will be apparent that, by thus winding
the wire, it can be tightened on the flange
32 engaged thereby and said flange will
thus be tightly bound upon the seat 30 en-
gaged thereby. It will be apparent that by
55 providing each of the rings 29 with tire
securing means such as described, it will be
impossible for the tire to become displaced
relative to the wheel rim.
It will be apparent, from the foregoing,
60 that when the rim 1 is shifted relative to
the axle 7, the bell crank levers 22 will
swing about their fulcrums 23 and will si-
multaneously compress the springs 25 in the
paths thereof, these springs thus serving to
65 retard the movement and therefore pro-ducing a cushioning effect similar to that
obtained by the use of an ordinary pneu-
matic tire. In view of the fact that the disk
10 is spaced from the outer disks 4 by anti-
friction devices 20 it will be seen that the 70
said disks can move relative to each other
without producing undesirable friction.
Furthermore as all of the working parts of
the wheel are housed they are fully pro-
tected from dust and moisture. 75
Where the wheel is to be attached to spin-
dles 40 such as used in connection with the
steering wheels of a motor vehicle, the
means employed for attaching the wheels to
the spindles are somewhat different from 80
those heretofore described. As shown in
Figs. 5, 6 and 7 the hub 41 and its extension
42 has a tapered bore 43 for the reception
of the spindle 40, one end of the hub being
counter bored as at 44 to receive a collar 45 85
on the spindle and also to receive anti-fric-
tion balls 46. A washer 47 of leather or the
like may be secured to the end of the hub
and projects back of the collar 45 so as to
prevent the admission of dust and moisture go
to the race in which the balls 46 are mount-
ed. The threaded end 48 of the spindle 40
has a slot 49 extending radially there-
through and the nut 50 engaging the thread-
ed end of the spindle has spaced lugs 51 95
extending from its outer face. A key 52 is
insertible through slot 49 and its ends are
adapted to be seated between the lugs 51,
the said key being held in such position by
a set screw 53 which enters the end of the 100
spindle and extends into the slot 49. A dust
cap 54 preferably engages the hub 41 and in-
closes the slotted portion of the spindle and
the parts coperating therewith. Anti-
friction balls 55 may be interposed between 105
the nut 50 and extension 42.
What is claimed is:-
1. A spring wheel including a tubular rim
having an inner annular slot, side disks se-
cured to the rim and spaced apart, a hub 110
extending through openings in the centers
of the disks and spaced from the walls of the
openings, a middle disk secured to the hub
and arranged between the side disks, said
middle disk having segmental ears outstand- 115
ing from the periphery thereof, bell crank
levers fulcrumed between the.side disks and
between the rim and the middle disk, one
arm of each lever projecting into the rim,
springs housed in the rim for retarding the 120
movements of the bell crank levers, and link
connections between the levers and the ears.
2. A spring wheel including a tubular rim
having an inner annular slot, disks secured
thereto, a hub extending loosely through the 125
disks, a middle disk secured to the hub and
between the side disks, ears outstanding
from the periphery of the middle disk, links
pivotally connected to the ears, bell cranklevers supported by the side disks and be- 130
