• The invention discloses a device which is connected to the underside of a motor vehicle.
  
• The device has a number of edged wheel discs which can be extended to engage an icy surface from the interior of a motor vehicle by the operator of the motor vehicle.
  
• The discs are mounted in a disc chassis which is connected to a hydraulic piston by a chassis bearing shaft.
  
• The hydraulic piston is connected to a pedal or hand lever within the interior of the motor vehicle so that the operator of the motor vehicle can extend the device when encountering an icy or slippery road surface to provide traction and prevent lateral movement of the motor vehicle.
  
• The hydraulic piston and chassis bearing shaft are contained within a housing which is attached to the undercarriage of the motor vehicle.
  
• In addition there is an alternate method provided comprising a blade which can be extended in similar fashion by the operator of the motor vehicle which will perform in similar fashion by digging into the icy surface to provide traction and to prevent the motor vehicle from sliding sideways .
  

Figure 1 Is an illustrative view of a motor vehicle without the anti ice skidding device.

Figure 2 Is another illustrative view , as shown in figure 1, of the motor vehicle not having any control on an icy surface.

Figure 3 Is an illustrative view of the same vehicle having the anti ice skidding apparatus installed.

Figure 3A is an enlarged view of the anti ice skidding device, as shown on the vehicle in figure 3, whereby the device having been extended by the motor vehicle operator will cut into the ice and thereby prevent the vehicle from spinning out of control.

Figure 4 is an enlarged view of the edged wheel discs contained within a chassis and having a disc chassis bearing arm.

Figure 5 is a side view of the motor vehicle showing the anti ice skidding device extended and cutting into the icy surface by the operator of the motor vehicle by means of a pedal connected to the vehicles hydraulic system.

Figure 5A is an enlarged view of the extended anti ice skidding device. the pedal is connected to a source of hydraulic fluid which will extend the hydraulic piston rod causing the chassis bearing shaft to pivot toward the roadway. The chassis bearing shaft forces the wheels disc members to cut into the icy surface.

Figure 5B is an enlarged cutaway view of the hydraulic piston showing the flow of hydraulic fluid against the hydraulic piston rod. The hydraulic piston has a spring for returning the piston rod back into the piston once the operator has removed pressure.

Figure 6 is a side view of the motor vehicle showing the anti ice skidding device in the disengaged position after the motor vehicle operator releases the pedal.

Figure 6A is an enlarged view of the apparatus showing the movement from an engaged position, shown in outline, to a disengaged position.

Figure 7 is an enlarged view of the apparatus showing the arc of movement from the disengaged position, shown in outline, to an engaged position.

Figure 8 is a description of the forces in moving the apparatus from a disengaged to an engaged position.

Figure 9 is a rear underside view of the apparatus in the engaged position.

Figure 10 is an illustration of an alternate embodiment of the chassis bearing shaft.

Figure 11 is an illustrative view of the Anti Ice Skidding Apparatus having the alternate embodiment of the chassis bearing shaft.

Figure 12 is a rear underside view of the Anti Ice Skidding Apparatus in the engaged position having the alternate embodiment of the chassis bearing shaft.

Figure 13 is a side view of a motor vehicle having a third embodiment of the chassis bearing shaft.

Figure 14 is a rear underside view of the Anti Ice Skidding Apparatus having the third alternate embodiment of the chassis bearing shaft.

Figure 15 is an enlarged view of the third alternate embodiment of the chassis bearing shaft moving from a disengaged position, shown in outline, to an engaged position.

Figure 16 is a side view of an alternate embodiment for the Anti Ice Skidding Apparatus. A blade is hydraulically connected to a pedal within the vehicle which is used by the motor vehicle operator to extend the blade member which will cut into the ice, thereby preventing any lateral movement of the motor vehicle.

Figure 17 is an enlarged side view of the alternate embodiment of the Anti Ice Skidding Apparatus. As the motor vehicle operator applies pressure to the pedal causing the hydraulic piston rod to extend applying a force to a cable. The cable causes the blade to be lowered into the engaged position. When the pedal is released the force is removed from the hydraulic piston causing the cable to move the blade to the disengaged position.

Figure 18 is a top view of a motor vehicle having the Anti Ice Skidding Apparatus installed on each side of the motor vehicle controlled by a single pedal having its own hydraulic reservoir.

Figure 19 is a top view of a motor vehicle having the Anti Ice Skidding Apparatus installed on each side of the motor vehicle controlled by a single pedal using the hydraulic reservoir of the brake system.
