Abstract

266,918. Joseph, N. C., and Joseph, B. C. March 19, 1926. Spinning. - Ornamented sheet metal hollow articles are made by spinning a sheet of the metal, e.g. aluminium, on a mandrel which is formed with the recesses, marks &c. to be produced on the finished article. A mandrel for use in spinning articles of smaller diameter at the mouth &c. comprises sections a decorated at e with hammermarks, punch-marks or drilling &c. to produce the required surface, the sections a seating in a recessed portion of the holder b which is screwed to. the machine spindle. One of the sections tapers from the centre to the periphery so that this section may be removed first in order to collapse the mandrel after the removal of the holder b.
