Abstract

Abstract An antiskid brake device including diaphragm means in communication with the fluid from the master brake cylinder and said diaphragm means having a biasing spring therein for normally urging a lever means in one direction, and a carburetor device with a fast idling cam wheel member, and said lever means being disposed to move said cam wheel member to a pulling position when the brakes are actuated and the brake fluid bears against the diaphragm means, so that the speed of the engine will be at a pulling speed when the brakes are applied to avoid skidding of the vehicle. The lever means is provided with means for adjusting its length including a telescoping arrangement and setscrew means. A rounded foot on the lever means fits a pulley on the carburetor wheel, so when the brakes are released, the foot will pull the wheel back to a closed position.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 127 words
In a vehicle, a carburetor provided with a fast-idling cam wheel, an antiskid device comprising an abutment element on said cam wheel, a diaphragm device with a resilient diaphragm therein, a linkage mechanism extending into said diaphragm device, means on said linkage mechanism drivingly engageable with said abutment element on the fast-idling cam wheel, biasing means on said linkage mechanism to normally maintain said resilient diaphragm in a nonactuating position, and a brake system fluid pressure supply means on the vehicle in communication with said diaphragm device to apply pressure thereto when the brakes of the vehicle are applied, to prevent the vehicle from skidding, wherein said linkage mechanism includes a telescoping section and said abutment element comprises a pulley with which said telescoping section is engageable.
Claim 2
Dependent Claim 127 words
In a vehicle, a carburetor provided with a fast-idling cam wheel, an antiskid device comprising an abutment element on said cam wheel, a diaphragm device with a resilient diaphragm therein, a linkage mechanism extending into said diaphragm device, means on said linkage mechanism drivingly engageable with said abutment element on the fast-idling cam wheel, biasing means on said linkage mechanism to normally maintain said resilient diaphragm in a nonactuating position, and a brake system fluid pressure supply means on the vehicle in communication with said diaphragm device to apply pressure thereto when the brakes of the vehicle are applied, to prevent the vehicle from skidding, wherein said linkage mechanism includes a telescoping section and said abutment element comprises a pulley with which said telescoping section is engageable.
Claim 3
Dependent Claim 38 words
The device of claim 1 wherein said linkage mechanism extends into said diaphragm device on one side of said resilient diaphragm and said supply means communicates with said diaphragm device on the opposite side of said resilient diaphragm.
Claim 4
Dependent Claim 34 words
The device of claim 1 wherein said telescoping section comprises a rod section and a sleeve section over the end of the rod section with a setscrew member for rigidly securing said sections together.
Claim 5
Dependent Claim 34 words
The device of claim 3 wherein a rounded foot is provided on said sleeve section to engage said pulley to pull said wheel back to a partly closed position when the brakes are released.
