The Wheel and cycling trade review . corrugations in the lug just as does the waterin the hydraulic system. Figures 3 and 4show the method adopted with the front forkcrown.

I have beenshown a machine constructed on these lines,and was told that it had been in use for somemonths. It looked all right. Another process which has the same endin view as Mr. Inshaw has, but attempts toarrive at it by brazing well, is the patent ofMr. Tayler, of the Shark ManufacturingCompany, Birmingham. It is a system ofproducing tube connections out of sheet steel,in which the act of brazing to the tube alsobrazes the component parts together. Figure. 9 shows the bottom ball-head connection as itis stamped out of the sheet and pressed toshape. The three rings are also cut out ofsheet steel, and their duty is shown in , but those who desire to have the ordinarypattern of lug can have these rings made ofmetal, which disappears in brazing, the rings,of course, holding all taut for the blowpipeto get to work. It is claimed that a perfectly brazed joint isthe natural outcome of this system, as thecapillary attraction of the open seams in theing causes a proper flow of the spelter and amore general distribution of the brazing thanis usual in ordinary work. Mr. Tayler also claims a reduction of costof building and a more perfect frame, be-cause of the absolute accuracy of the pressedwork and the extreme lightness of the con-nections made out of wrought sheet steel. The most interesting fitting, however, ofthe group is the bottom bracket, or, as youcall it, the crank-hanger, Fig. 12. It is builtup in three sections around a central t
