Abstract: 2074. Barthels, F. W., and Schaefer, W. Feb. 1. Me t a l pipes and tubes.-In flanged tubes and the like, the flange a is chamfered &c. at c &c. to facilitate the attachment of the tube to it before brazing, and it has a collar b provided with a groove d having a number of passages e leading therefrom to the tube to hold the brazing-material. When heated, the brazing-material melts and brazes the joint, without danger of fusing the tube.
