We believe the Hupmobile to be, in its class, the best car in the world

A miniature tup hammer, dropping from a fixed height to the surface of the metal, determines in one operation the hardness, toughness, and strength of all the bone-hardened and heat-treated parts of the Hupmobile.
This instrument, the scleroscope, enables us to produce cars of uniform wearing quality--parts of uniform hardness and strength.
And the test by this device is only one of several similar trials to which Hupmobile parts are subjected.
In the picture the operator is proving the transmission drive shaft--one of the finest pieces of mechanical work in the car.
To withstand the severe usage which this shaft undergoes, because it bears the brunt of all the gear-shifting, it is made from specially treated acid open hearth nickel steel--the hardest and toughest that the laboratory experts have been able to devise.
It is forged, machined, bone-hardened, double heat-treated; and all the surfaces, including the four integral gear keys, are ground.
The little hammer in the scleroscope is dropped, and its rebound to a figure on an arbitrary scale indicates the hardness of the metal.
A magnified reproduction of this scale and its corresponding figures in pounds of elastic limit is shown.
On the Hupmobile transmission drive shaft, the hammer must rebound to a point between 75 and 85 on the scale. Not below 75, to make certain the metal is hard enough; not above 85, to make certain it is not too hard.
This means that the elastic limit is 190,000 to 220,000 pounds to the square inch.
In other words, pressure of 190,000 to 220,000 pounds must be applied to produce a fracture--a margin of safety far beyond the most secure requirements.
On other parts, other limits are fixed: because various parts must have varying degrees of hardness to give the longest service.
And this is simply another stone in the foundation of the belief stated above.
