Important Patent Decision, Brookfield, Hemingray, Brooke dispute published in this issue

An Important Patent Decision.

WE print this week, from the Official Gazette of the Patent Office, an important decision of the Commissioner of Patents, reversing the action of the Board of Appeals in regard to the invention of the screw thread improvement on glass telegraph insulators.

If glass insulators are to be used for telegraphic purposes as all, the screw thread is an important improvement, and one which is valuable. It will be seen that Commissioner LEGGETT has awarded the priority of this invention to Mr. BROOKE, and against MESSRS. BROOKFIELD and HEMINGRAY, who also claimed it. We presume that this finally settles the question which has been in dispute for a long time.

Mr. LEGGETT'S decision appears to be just and equitable, an although an appeal may be legally taken to the United States Courts, it is not likely that his decision would be reversed.
