Samuel Blatchford, Mosler Safe Lock Company v. Mosler Bahmann Company…
“ Such use of the templet as a pattern is nothing new. It is clearly shown by the testimony that cutting an opening in one web of an angle bar to permit the bending of the bar to an angle or curve, was known and used before the date claimed by complainant's assignor for his invention. Different shapes of cuts and openings are shown in exhibits put in evidence by respondents. Unless the precise cuts and shape of opening shown in the drawing attached to the specification forming part of the letters patent are patentable, the claims are worthless. ”
