Abstract: 25,520. Barthels, F. W. Dec. 23. Flanging. - Flanges are formed on tubes by compression on the apparatus shown in Fig. 1. The tube end to be flanged is placed upon the hot mandrel b as far as the collar c, and the tube is held between the collar c and the cap h provided with an adjustable screw-nut g on the rod f, which forms an extensinn of the mandrel. By heating the tube end, hammering the head d of the mandrel, and tightening the screw nut g, the material is compressed, and by hammering is straightened, bulged, and compressed until a flange with thickened walls has been formed against or in the collar c. The collar may be flat, and the flange hammered conical. The invention is particularly applicable to copper tubes for steam connections.

Abstract: 11,859. Barthels, F. W. June 7. Metal pipes and tubes.-To unite a flange to a pipe or tube, such as a copper steam pipe, the flange a is formed with a boss b, in which is a circumferential groove c. Axial grooves d extend at regular intervals across the groove c. The pipe e is spun or hammered into the groove c, and the grooves d are filled with hard solder, which is heated from the front. The end of the tube may be flared at h.

Abstract: 22,962. Barthels, F. W. Nov. 17. Angle-pieces, junction pieces, and the like; bends.- Relates to forged metal tubular connections, or tees, elbows, and crosses, for steam conduits and the like. The connection is made in a single piece and without brazed joints from a seamless tubular blank having a diameter corresponding to the largest cross-dimension of the article to be formed. Such connection is produced by repeated contraction of the metal by hammering at certain parts, and then shaping the material of the parts left into the required form. One stage in the formation of a tee joint is shown in Fig. 7, and an elbow connection is shown in Figs. 10 and 11.
