    /WWW A.D. 1876, November. N° 4597. Electric Motors. LETTERS PATENT to Edward Henry Cradock Monekton, of Fineshade, North¬ amptonshire, for the Invention of Improvements in Generating and Applying the Electric Current and in Producing Motive Power, and in the Apparatus necessary for Carrying the same into Effect.” Sealed the 23rd February 1877, and dated the 28th November 1876. COMPLETE SPECIFICATION filed by the said Edward Henry Cradock Monekton at the Office of the Commissioners of Patents on the 28th November 1876. Edward Henry Cradock Monckton, of Fineshade, Northamptonshire. “Im- 5 PROVEMENTS IN GENERATING AND APPLYING THE ELECTRIC CURRENT AND IN Producing Motive Power, and in the Apparatus necessary for Carrying the same into Effect/’ Firstly. I construct complete magnetic circles of either permanent or electro horse-shoe magnets with their coils joined together by placing them in juxta- 10 position round two circular frames, each pole of each magnet being consecutively placed so as to face the opposite pole of the next magnet, thus, N to S and S to N all round; this is effected either by placing the magnets laid flat round the peripheries of the frames or by bending the magnets or by making them in pieces to be joined together in any desired form, so as to be arranged vertically with their 15 poles turned aside. By making the magnets flat instead of round they can be packed closer, the same consecutive polar arrangement being made. By separating the poles a sufficient distance one or more plain iron or magnetised steel discs can be introduced packed side by side almost in contact, which arrangement will also unite into one large magnet the entire circle of smaller ones. These discs can be 20 arranged so as to revolve in any way desired, they may also be made to break contact by being slotted from the circumference towards the middle. By sub¬ stituting for this disc an electro-magnet formed like a reel with slotted ends or poles or in lieu of it a revolving wheel formed of electro-magnets, both wheels being insulated from their axles, and by revolving either in contact with the poles of the 25 magnets arranged in circles, as above described, the electro-magnetic circles will be alternately completed and broken, and by a suitable arrangement any current generated can be drawn off.
