Description:

Abstract:

This invention relates to improvements in scarifying attachments such as are applied to road engines or power road rollers and are used in tearing up old roads by means of teeth which are forced into and through the surface of the road for leveling and subsequent repair of the same.

Claim:

The combination with a road engine of a scarifying attachment therefor comprising a toothed member suspended transversely beneath the rear of said engine, draw bars secured to said toothed member and pivotally connected to said engine, a spring for raising said toothed member and its suspending means connections between said spring and said toothed member affording a decreasing leverage for the spring as the latter stretched in lowering the toothed member onto the ground, and fluid pressure operated means for holding said toothed member on the ground in opposition to the action of said spring.
