- Dyer-- Have I a patent on an ordinary governor Steam Eng) made to lift a lever up & down according to the speed which lever simultaneously raises or depresses several lefers or springs provided with contact points to all in series so the current is broken in several places simultaneously to prevent spark and these points put right in a main circuit the governor being run by a motor for regulating the motor speed by cutting off the entire current at intervals I know I have it in some regulators but have I used it to regulate motors if not a good claim can be obtained perpare a patent Down at Menlo a long time ago Ott made dies & we drew bamboo ect through round dies to make even cylindrical fibres we made only a few lamps-- I now want to tke the subject up again-- Can I apply for a patent and get claim for a cutting die-- not a drawing die but one that cuts so that fibres or woody matter can be cut to shape-- whether the dies are split or solid ie holes (dynamo drawing) Patent this-- part of the face of the field is cut away and large wire wound parallel with the armature wire & with a carrying capacity equal to the armature and as arranged as to resistance current and turns of wire that its magnetizing effect on the armature is equal to the wire on the armature. The current from the armature is passed through this fixed coil in such a direction that it magnetizes the armature just the opposite to the magnetization due to the wire on the armature this causes the armature to have no magnetic [Dyer made notes in response]
