Opinion

SHOWALTER, Circuit Judge.

This is an appeal from a decree wherein appellants were adjudged infringers of the first claim of letters patent of the United States No. 379,550, issued March 13, 1888, and of the second claim of letters patent of the United States No. 380,068, issued March 27, 1888. S. F. Welch (assignor to appellee) was the patentee in each instance. Each of these patents is for a “new and useful improvement in road graders.” In the specification of the first, the patentee says:

“My invention relates to that class of road graders in which the scraper is supported by a frame mounted on wheels, and in which it can be adjusted vertically and laterally, and can be set at different angles of diagonal adjustment to the roadbed.”

Following are two of the drawings forming part of the specification of this patent:
