"Vintage Machinery" entry for Houston, Stanwood & Gamble Co.
"My invention relates to forging and bending dies and has for its object chiefly to provide a suitable die for forging wrought iron bars into shapes suitable for sections of electro-magnet fields, that is to say, of an approximately horseshoe shape..."

The assignee had, a couple of years earlier, co-founded steam engine maker Houston, Stanwood & Gamble Co. See patent 497,356 for a possible use of this invention (an electric motor-truck); however, so far as we are aware, HSG never made any sort of electric vehicle or anything else electric.
