Abstract

20.845. Dick, Kerr, & Co., [Braun, R.]. Sept. 11. Electro-magnets.-A magnet for electromagnetic brakes having renewable wearing shoes is proportioned so that the magnetic induction at the points where it makes contact with the shoes is not less than that at any other cross-section of the magnet. Fig. 1 shows one form, the magnet being tapered down so as to be of least crosssection at the points of attachment to the shoes A<5>, which are attached by dovetail portions A<4>. In a modification, the attaching surfaces of the shoes and magnet are of zigzag form. The magnet is in four parts A<1>, A<2>, A<3>, A<1> for convenience in fitting the field coils.
