Pugh, R D

A vehicle performance computer is described in the form of a circular slide rule for determining the relationship between the vehicle performance parameters of time, distance, braking, coasting, and acceleration as a function of vehicle weight, horsepower, speed, and roadway percent grade, the computer comprising: substantially planar base having a center and also including: a first logarithmic scale arcuately disposed about the base center and having indicia associated representing the speed of the vehicle; a second logarithmic scale arcuately disposed in a predetermined position with respect to the first logarithmic scale and having indicia associated representing the weight-to-horsepower of the vehicle; a third logarithmic scale arcuately disposed about the base center in a predetermined position with respect to the first and second logarithmic scales and having indicia representing the required time for the vehicle to alter its speed from one particular speed to another; a substantially planar intermediate slide having a center and rotatably mounted atop the base both the centers are aligned, the intermediate slide including: a fourth logarithmic scale arcuately disposed and having indicia associated representing the percent grade upon which the vehicle is traveling; a window arcuately disposed about the intermediate slide center in a predetermined position with respect to the fourth logarithmic scale for viewing the second logarithmic scale in cooperative viewable alignment with the fourth logarithmic scale; a fifth logarithmic scale arcuately disposed about the intermediate slide center in a predetermined position a sixth logarithmic scale arcuately disposed about the intermediate slide center in a predetermined position with respect to the fourth and fifth logarithmic scale.
