LTD., 30 & 31, Furnival Street, Holborn, Loudon, E.C. FOR TWENTY YEARS Heywood and Bridge’s Patent FRICTION CLUTCHES have set the standard of efficiency by which all other types are judged. Their merit lies not in intricate ingenuity, but in simple, positive action, well=balanced design and sound material and workmanship. They pick up the drive easily, hold it firmly, and ease wear and jar on bolts and machinery. Do not therefore be put off with any apparently similar type or a mere imitation, but SPECIFY HEYWOOD & BRIDGE’S PATENT. jMnrxWrite for Catalogue of Millgearing and Friction Clutches to the patentees and sole makers:— DAVID BRJDGE & CO.
