Utility Patent Application: Title: Wheel Beadlock Design. Inventor: Ricehouse, Daniel I.
Background of the ion
Field of the invention: This invention relates to the general field of securing tires
to wheels. More specifically, the invention relates to a bolt with a revolutionary ball seat
that allows a bead ring with an elongated hole to pivot around the bolt while the bolt
ns a bead ring against a wheel to effectively secure a tire to the wheel, and to a
method of preventing a tire from moving inward from an inner rim of the wheel as well as
not slipping around the wheel as the vehicle accelerates or decelerates.
Brief Description of Invention: In one embodiment, the invention comprises
improved bolts and bead rings, which in turn create an improved clamping mechanism to
secure a tire between the bead ring and the wheel. The bead ring includes a bead ring
ball seat manufactured into it with an ted pilot hole. The bolt has a head, a ball
seat, a thread and a bolt pilot. The threads engage with a threaded section on the wheel.
The threads can be any diameter and y of threads per inch. The ball seat bolt
nestles with the bead ring ball seat, allowing the bead ring to pivot as the bolt threads
engage with the threaded n in the wheel, g the bead ring toward the wheel to
secure the tire bead in between the wheel and the bead ring. As the bead ring is forced
down upon the wheel through rotation of the bolt, eventually the bead ring contacts a pivot
point on the wheel, at which point the outer edge of the bead ring is leveraged against
the tire bead bundle, pressing down upon the tire bead to lock it in place against the
wheel. Because the bead ring can pivot about the bolt within the ball seat and elongated
pilot hole, the bolt is not stressed as in the prior art.

In another ment, the barrel of the wheel also has an ed safety bead
that prevents the tire from moving away from the bead seat of the wheel. The area
between the safety bead and the outer lip of the wheel (tire bead seat area) receives a
measured (RA) surface roughness finish process to achieve the maximum co-efficient of
rubber to aluminum that prevents the wheel from slipping rotationally inside the tire as the
tire revolutions are quickly increased or decreased as it often the case in auto racing.
In a third embodiment, the invention provides a washer with a ball seat to be
attached to the bead ring. The means of attachment sly has to be very secure, so
welding the washers around existing pilot holes in an existing wheel is a preferred
embodiment of the invention. Because the washer has a ball seat, one of the bolts
described more fully in this invention can be used to pivotally secure the bead ring over
the tire bead bundle against the wheel.
Statement of the Problem: The open edge of a tire is called a tire bead and in
the middle of the tire bead is called a tire bead bundle. The tire bead bundle is usually
made of metal or some other non-compressible material. As tires wear, they need to be
replaced. To effectively seal a new tire over a wheel, the tire bead bundle has to be
clamped between the wheel and a bead ring, with several bolts extending through pilot
holes in the bead ring and having threads that engage with ed sections in the wheel.
The bolt has to withstand considerable stress as it has to clamp the tire bead bundle in
n the bead ring and the wheel with enough pressure such that air does not escape
the tire.

Utility Patent Application: Title: Wheel Beadlock Design. or: Ricehouse, Daniel I.
As the bead ring is tightened on the wheel, the bolt has to undergo significant
stress as the angle between the bead ring and the wheel is not consistently el,
commonly referred to as joint face angularity, even the smallest angularity errors can have
a catastrophic effect of the fatigue life of a bolt. This is particularly true for the bolt head,
which is often, for at least part of the process, pressing t the bead ring at an angle
such that only a portion of the bolt head is touching the bead ring. This problem is
ularly acute in fields such as racing and off-road tire installation, where time is
essential and workers do not take time to worry about the stress they may be placing on
the bolt head. One problem faced is in tire installation during bolt snapping, the bolt head
is no longer keeping the tire bead bundle compressed between the bead ring and wheel;
therefore air may escape to flatten the tire, or an asymmetry of the wheel may cause other
bolts to break, resulting the tire completely g off from the wheel. When this happens
in a racing car, it can be catastrophic for both the driver of that car and any nearby drivers.
Another problem faced by automobile owners, ularly race car drivers, as that
when a tire is raced with low psi, there are two tendencies that can lead to catastrophic
tire failure. First, with very little psi to hold the tire bead of the tire against the wheel, it is
easy for the tire to move inward from the inner rim of the wheel and de-bead. This can
lead to rapid deflation of the tire or a severe tire imbalance, causing tire failure. Second,
with low psi tires, as the driver rapidly accelerates or decelerates the vehicle, the tire has
a tendency to “spin around” on the wheel so the tire and wheel no longer rotate as one,
as there is nothing to lock it against the barrel and inner rim of the wheel. This dual rotation
can put an unacceptable amount of stress on the sidewall of the tire, resulting in
rophic failure of the tire ll construction.

The prior art has several examples of attempts to resolve these problems. For
example, the bead ring is bolted down upon the wheel by a non-pivoting bolt where this
is no pivot point for additional ge. Another example is found in US Patent No.
9,481,205 to Rider, et. al., which rates a device with a threaded stud rather than a
traditional bolt. However, the device neither addresses the m of stressors upon
non-pivoting bolts nor provides the additional benefits of leveraging the bead ring upon
the wheel that is taught by the current invention.
Thus, there has existed a need for a better means by which a tire bead can be
secured between a bead ring and a wheel and ted from moving inward from the
bead seat of a wheel or rotationally spinning around on the wheel.
Statement of the Invention: In order to solve the above problems, the present
invention provides a solution by utilizing a bolt about which a bead ring can pivot and a
fulcrum on a wheel that can be leveraged upon to achieve a superior seal between a bead
ring and a wheel over a tire bead. The bead ring is manufactured with a number of bead
ring holes, each of which has a bead ring seat and an elongated pilot hole, which allows
the bead ring to pivot around the bolt which being tightened. The bolt has a head, a ball
seat, a threaded section, or thread, and a bolt pilot. The ball seat mates with the bead
ring seat and the pilot hole in the bead ring is elongated greater than the diameter of the
thread section of the bolt allowing the bead ring to pivot several degrees on either side of
the bolt as the bolt threads engage threads in the wheel to prevent threading of the bead
ring, pulling the bead ring toward the wheel. As the bead ring is tightened on the wheel,
ally the bead ring ts a fulcrum on the wheel, at which point the outer edge
of the bead ring is leveraged against the tire bead bundle and pressed down upon the tire

bead to lock it in place against the wheel. Because the bead ring can pivot about the bolt
within the elongated pilot hole, the bolt is not stressed in joint face angularity or ing
as in the prior art and provides a more secure attachment of the tire to the wheel.
The invention onally comprises a safety bead on the barrel of the wheel close
to the inner rim. This prevents the tire from moving toward the center of the wheel, a
m particularly acute with low psi tires such as those found on sprint cars and
dragsters. In n the safety bead and the inner rim, a measurable surface (RA) finish
is created to the maximum coefficient of friction of rubber to aluminum, to prevent the tire
from rotationally slipping around the wheel as the car accelerates and rates.
It is therefore an object of the present invention to e a superior mechanism
by what a tire can be attached to a wheel.
An additional object of the invention is to provide a bead ring with a bead ring seat
and an elongated pilot hole that will allow the bead ring to pivot around a bolt as it is
screwed into a wheel.
A further object of the invention is to provide a wheel with a fulcrum, against which
a bead ring can be leveraged.
Another object of the invention is to provide a superior method of securing a tire in
a wheel, including tires used in race cars, off-road vehicles, airplane wheels.
Another object of the invention is to provide a “safety bead” on the barrel of the
wheel close to the inner rim to prevent the tire from moving toward the center of the wheel,
a m particularly acute with low psi tires.

A r object of the invention is to provide the maximum coefficient of friction
surface (Measured RA) finish between the safety bead and the wheel bead seat to
prevent rotational tire-slip around the wheel as the car accelerates and rates.
A final object of the invention is to provide a bolt with a ball seat where the ball seat
can mate with a bead ring seat and allow the bead ring to pivot about the bolt through an
elongated pilot hole as it is being d into a threaded bolt hole in a wheel to prevent
joint face angularity and threading.

According to one embodiment of the ion, the density of threads per inch of
3/8” bolt is 16. In some embodiment of the invention, the density of threads per inch of
3/8” bolt is 24.
Similarly, referring now to the ion in Fig.7a and Fig.7b is a 5/16” bolt
according to one embodiment of the invention, showing two types of heads 1, the ball

Referring now to the invention in Fig.8, Fig.9 and Fig.10 this sequence of figures
illustrates the beadlock tightening s.
Fig.8 is a side view of the ion at the beginning of the tightening process. It
can be seen that in the initial engagement, the threads 3 of the bolt is d with
threads section in the wheel 8. The ball seat 2 of the bolt is nestled in the bead ring seat

(better shown in 12 of Figure 13) of the bead ring 5. The bolt is in a 90 degree vertical
configuration, so that a bit of space in the enlarged pilot hole 9, which will allow the bead
ring 5 to pivot slightly around the bolt as the bead ring 5 is tightened against the wheel 8.
As the tire have a tire bead 6 and a tire bead bundle 7. The tire bead 7 is made of metal
or some other non-compressible material. Tire bead ssors 11 are on above and
below the tire bead bundle 7, which will eventually be ssed n the wheel 8
and the bead ring 5 for sealing the tire bead bundle 7. It the goal of a bead lock to put
enough pressure on the tire bead compressors 11, such that no air can escape from the
inside of the tire, and that the tire is secured to the wheel.
Fig. 9 is a side view of the invention in the middle of the ning process. It can
be seen that the bolt head 1 has been rotated, cause the bolt thread 3 to further engage
the mating thread holes of threaded section in the wheel. This has pulled the bead ring
down toward the wheel 8. There is not yet enough force to compress the tire bead
compressors 11, so the bead ring 5 rotates slightly in the bead ring seat (better shown in
12 of Figure 13) until a pivot point or fulcrum 10 is contacted, which creates a fulcrum with
the bead ring 5 contacting the wheel 8. The bolt in this figure has been further screwed
into the wheel 8, and the bead ring 5 has pivoted slightly, in a preferred embodiment
approximately 4 degrees, around the bolt, as the bolt maintains a direct, 90-degree angle
with the threads in the wheel 8. This ts part of the bolt head 1 from undergoing
undesirable stress as the entire head 1 is not uniformly pressing down on the bead ring
. The enlarged pilot hole 9 now shows no gap, as that gap has been filled by the thread
3 as the bolt pivots, but rather, a gap appears on the opposite side of the bead ring.

Fig.10 is a side view of the ion at the end of the tightening process. The tire
is ed and approximately 0.0125’’ rubber remains on each side of tire bead 6. Upon
hitting the fulcrum 10, the bead ring 5 leverages the pressure from the bolt as the bolt is
further tightened, and begins to put pressure on the tire bead ssors 11 against the
tire bead bundle 7. Since the tire bead bundle 7 is not compressible, the tire beach
compressors 11 get flattened to effectively both seal air inside in the tire and to prevent
the tired bead core 7 from escaping its confinement between the bead ring 5 and the
wheel 8. Because of the use of the fulcrum 10, tires of various thicknesses can be used
on the same wheel without a decrease in the security of the lock between the wheel 8
and the bead ring 5.
Fig.11a, Fig.11b and Fig.11c show side view of the invention in steps of securing
tire bead 7 through the enlarged pilot whole 9 and allowing the bead ring 5 to pivot slightly
around the bolt as the bead ring 5 is tightened against the wheel 8. Because of the
enlarged pilot hole 9 in the bead ring 5, the bolt is not unduly stressed because the bead
ring 5 can pivot about the bolt, although it would cause less stress had the bolt had a ball
seat, as is illustrated in figures 8, 9 and 10.
Fig.12 is a side view of a wheel 8 showing the location of the fulcrum 10 and the
safety bead 13. The barrel of the wheel 8 has a safety bead 13 that prevents the inner
side of the tire from moving away from the inner rim of the wheel 8. The gap between the
safety bead 13 and the inner wall has an RA coating on it that prevents the tire from
slipping along the wheel 8 as the tire revolutions are y increased or decreased as it
often the case in auto racing.

Fig.13 is a perspective view of a bead ring 5 with a bead ring seat 12 and an
enlarged pilot hole 9. It can be seen that the enlarged pilot hole 9 is not circular, but
rather ted, or “racetrack” shaped such that the bead ring 5 can pivot around the
bolt, but only along a single axis. This design is very useful in zing stress on the
bolt as it pulls the bead lock against the wheel.
Fig. 14a and Fig.14b are beadlock designs of two prior arts and Fig.14c is beadlock
design of the current ion comparing their effectiveness. Fig.14a is a prior art
beadlock design and it can be seen that the bead ring 5 is pulled down at an angle against
the tire bead 6 and the wheel 8. This result in the bottom of the bolt head 1 digging into
the top of the bead ring 5, causing binding up to 20 foot pounds and substantial stress
upon the bolt head. Indeed, the asymmetrical pressure on the bead ring 5 quickly leads
to deformation of the bead ring 5, such that when tires are ed in the future, it is even
more difficult to achieve a strong seal. This ly leads to bolts snapping or the bolt
heads shearing off, either of which can result in catastrophic failure.
As shown in Fig.14a, where a significant amount of force on the bolt head is
applied, the bolt can be broken or bent at installation. As it is shown in formula, when
Fbead= Fbolt then torque on the bolt becomes Mbolt= Fbead × d and Mbolt= Fbolt× d (where
Fbead= Force on bead, Force on bolt, Mbolt= Moment (or torque) on the bolt and d=
perpendicular distance). Further it is apparent that the erratic bead force is applied on the
bolt due to which bead ring galling is ed and incorrect torque reading may be
obtained. Further, the force applied on the bead ring 5 is at incorrect angle, therefore
significant deformation on the bead ring 5 is seen after some uses.

Fig.14b is another prior art bead lock design which shows how the bead ring 5
has an elevated section which creates a cavity into which the tire bead 6 nestles, that
once the bolt has been tightened into the threaded hole in the wheel 8, the pressure of
the tire bead 6 is at its maximum. Further it shows that the erratic bead force is applied
on the bolt due to which bead ring g is occurred and incorrect torque reading may
be obtained. Further, the force applied on the bead ring 5 is at incorrect angle, therefore
significant ation on the bead ring 5 is seen after some uses. As it is shown in
formula, when Fbead= h× Kbead which is also Fbead= Fbolt- ent) then torque on the bolt
becomes Mbolt= Fbead × d (where Fbead= Force on bead, Fbolt=force on bolt, Mbolt= Moment
(or torque) on the bolt, d= dicular distance, h is height of the tire bead and Kbead is
compression).
Fig.14c is bead lock design of the current invention shows how the pivoting bead
ring 5 combined with the fulcrum 10 on the wheel 8 allows for tighter seal on the tire bead
6 by the wheel 8 and bead ring 5. As shown in Fig.14c, it shows increasing rate of bead
force. Further, the bolt force splits between bead ring and fulcrum. It maximizes load
transfer. Ball seat 2 and bead ring 5 design compensates for angular errors, no galling,
proper bolt torque is provided. Which is further explained in formula, where Fbead= Fbolt-
Ffulcrum and then torque on the bolt is Mbolt= Fbead × crum× c (where Fbead= Force on
bead, Fbolt=force on bolt, Ffulcrum=force on m Mbolt= Moment (or torque) on the bolt,
d= perpendicular distance, c= perpendicular distance and f= fulcrum displacement).
Fig. 15 is a chart illustrating the extra torque put on bolt heads according to the
designs of the prior art. At varying amounts of bead compression (X axis) the darker
circles represent bolt failure at increasing amounts of force for the prior art, with the lighter

circles representing the failure points for this invention. As can be seen, for the most
common amounts of bead compression, the current invention allows the bolt to take 1,000
pounds or more extra pressure above what a bolt in a prior art wheel/bead ring could take
before failing.
Fig. 16a, Fig.16b, Fig.16c, Fig.16d and Fig.16e show the re Film Test
Results. Fig. 16a and Fig.16b show how a traditional new bead ring/wheel/bolt
combination, Fig.16c and Fig.16d show how it loses clamping force over time with more
uses, because of ring deformation, while in e is the current invention shows no loss
of force over more uses.
Fig. 17 shows the results of a Pressure Film Tests on various prior arts and the
current invention, where the pressure film test shows the amount of clamp force.
Fig. 18a, Fig. 18b, Fig. 18c and Fig. 18d rate several alternative
embodiments of the invention. a is side view of the 3/8” bolt, having 12 points on
the head 1, the ball seat 2, the thread 3 and the pilot hole 4. Fig.18b is side view of the
3/8’ bolt having a Dome Nut 14 on a stud 15. Fig.18c is side view of the 3/8’ bolt with a
Dome washer 16, a Nut 17 and a washer 18 on a stud 15. Fig.18d is side view of the
3/8’ bolt with a Dome washer 16.
Fig. 19a is a perspective view of a second embodiment of the invention showing a
bolt with non-threaded section 19 for pivoting in a bead ring 5, where a washer 18 with a
washer seat 20 has been attached to a bead ring 5.

Fig.19b is a perspective view of another embodiment of the invention showing a
bolt with non-threaded n 19 is pivoted with the bead ring 5, where a washer 18 with
a washer seat 20 has been ed to a bead ring 5 creating a pivot room 21. Because
the washer 18 has a ball seat 2 be used to pivotally secure the bead ring 5 over the tire
bead bundle 7 against the wheel 8.
Fig.20 is a side view of the safety bead 13 and non-skid application. The invention
additionally comprises a safety bead 13 on the barrel of the wheel close to the inner rim.
This ts the tire from moving toward the center of the wheel, a m particularly
acute with low psi tires such as those found on sprint cars and dragsters. In between the
safety bead and the inner rim, an RA finish 22 is created, to prevent the tire from sliding
around the wheel as the car accelerates or rates. By preventing the tire from sliding
around the wheel or moving away from the rim, the combination of the safety bead and
the RA finish 22 avoids the potentially catastrophic failures caused by over-stressing the
sides of the tire and/or a sudden imbalance of the tire on the wheel.
Fig. 21 shows side view of a preferred embodiment of Fig. 20 with the safety bead
13 and the RA finish for non-skid application. For an exemplary embodiment, the RA finish
22 is 0.866” provided for 14” rim width.
In particular, it is noted that the same function can be completed by both the “bolt”
and “washer” version of the invention.
It should be understood that while the preferred embodiments of the invention are
described in some detail herein, the present disclosure is made by way of example only
and that variations and changes o are possible without departing from the subject
