METHOD OF MAKING SUSPENSION INSULATORS OF GLASS.
1,542,588 June 16, 1925. Erich Schott, Jena, Germany, assignor to the firm Jenaer Glaswerk Schott & Gen., Jena, Germany. Filed 2/6/25. This invention includes a method of making suspension insulators of glass, consisting in this that a glass body is first shaped in such a way as to receive a hollow space, adapted to receive a clapper, that thereupon a clapper is inserted and finally the glass is pressed round the clapper, so that after the hardening of the glass the clapper cannot be pulled out from the hollow
 |
space. It is easily possible to leave an interval between the glass body and the clapper, to avoid any objectionable influences of the clapper upon the glass.
