Abstract
404,466. Electric trolly poles. BRECKNELL, WILLIS, & CO., Ltd., and WILLIS, A. M., 59, Victoria Street, Bristol. Jan. 30, 1933, No. 2908. [Class 104 (iii).] The pole arm 2 is at least one-fifth the combined length of the pole arm and pole 1, and the latter has a smaller moment of resistance to binding than the pole arm. The pole spring or springs are anchored to the pole arm at a point distant from the base 3 at least oneseventh of the length of the pole arm and pole. Specifications 376,494, 404,467, and 404,468 are referred to.
