Title of Invention: Roll Cage Crush Box
Abstract: This invention is a simple design modification to a standard bolt‐in roll cage base plate. Allowing some controlled compression of the crush box allows it to absorb greater loads than a plate. Rather than allowing a tube and base plate to press through the floor of a vehicle in the event of a major application of force, the crush box will deflect, dissipating much of this force to the rest of the roll cage and preventing the floor from being compromised.
Prior art includes: Patent numbers 3622177, 5048994, and 5461409, as well as Autopower products.
All prior art depicts roll cage bases solidly attached to the floor of a vehicle with bolts. In this traditional design, with a roll cage mounted solidly to a floor, structural issues arise. Floor pans are typically designed with little regard for strength other than seat mounting capabilities. As a non‐structural component, the floor pan is non‐ideal to absorb the full force of a rollover incident. In the event of a rollover, the force applied to the roof and roll cage can lead to roll cage tubes punching through the floor of a car. This generally retires the car from use. More importantly, this can be extremely dangerous for the driver of the vehicle. When the cage drops, the driver can be struck or pinned by it.
Description: The Roll Cage Crush Box functions by allowing some compression to occur upon the application of load. The boxes deform and absorb load while increasing the event time, allowing for the dissipation of force across more of the roll cage. The crush box is welded to the bottom of the roll cage tube. This box is then part of the mounting assembly. Bolts and nuts mount the Crush Box and two Flat Plates to the floor of the car. The crush box assembly is designed for use primarily in the main hoop of the roll cage, where it mounts to the floor. Other mounting locations are more structurally sound, but would still benefit from the addition of Crush Boxes.
Claim: This invention allows bolt‐in roll cages to be safer by spreading loads across more of the roll cage and car structure.
Summary: The Crush Box design mitigates the problems outlined in the “Background” section through a simple design modification. Rather than mounting roll cage tubes directly to flat plates on the floor of the vehicle, boxes are added to the mounting areas. Perching the tubes on boxes allows for deformation that is not coincident with floor failure. During a rollover, the tubes will press on the boxes and deform them instead of pushing through the floor, as is the case with the traditional design. While the box is deforming, more time is also allowed for the force to dissipate to other areas of the rollcage. Granted, given a large enough load, failure of the floor will occur; but this failure will take place under much more extreme loading conditions. This increased resistance to floorpan failure increases driver safety and vehicle longevity.
Conclusion: The Roll Cage Crush Box addresses a problem with bolt‐in roll cages through a design modification. Where traditional cages bolt to flat plates on the floor of the car, the Crush Box design calls for tubes to be mounted to Crush Boxes which are mounted to the floor. This allows for increased load resistance, which ultimately enhances driver safety and vehicle longevity.

Title of Invention:
Air Pressure Thread Tapping Tool with provisions for expelling chips with air pressure and vacuum, or any combination of each.
This air pressure tap tool is an evolution of thread cutting tools.
Recent automotive technology has allowed spark plugs to be installed in cars and run for many years. The resulting service issues include the spark plug thread failure, requiring oversize tapping of the hole. While this air pressure tap tool addresses that need, there are no restraints upon its use wherever thread cutting results in the chips entering the hole causing damage or time consuming clean up.
Prior art indicates potential use in the aerospace and medical fields also.
This air tapping tool recognizes prior art, patents 7160063, 7334969.
Current thread taps will allow some chips to pass into the hole. Taps currently in use have little control over the cutting chips.
This air pressure tap tool is simply a tap with a hollow bore allowing air pressure or vacuum to be introduced into the work area. Provisions are made to isolate two passageways, allowing both pressure and vacuum to be applied simultaneously.
When used in an engine, having the valves closed, the pressure inside the chamber expels the cutting chips clear of the chamber. Air holes in the flutes aid in breaking the chips off and expelling them from the work area through the flute slots.
Uses in the aerospace field include tapping holes for fasteners in blind or hard to access situations. IE, inside of the wing or other ‘blind box” situations.
The “Air Tap’s” vacuum ports will extract the cutting chips clear of the work area .
Uses for the medical field are possible in the area of tapping bones.
Again, the vacuum will allow removing any debris from the work area.
