A patent has jnst been grantod Loring Piekering, one of the editora and proprietors of the Evening Bulletin and Morning Cali, of San Franciaoo, for a metbod of rapid telegraphing of fao símiles of stereotype plates. It is olaimed that by the process an entiro page of newspaper can be transmitted by telegraph in frora 15 to 30 minutes, delivering copy direetly frora the instrument in such a form that it can be handed immediately to the printers. In other words the copy will be a substantial reproduction of the original, except that it m ay be givon in a largor sized letter if so de8ired. The stereotype requires no preparation for the purpose of telegraphic transmission other than filling till its depressions or spaces betwoen the faces of the latter with a non-conducting snbstanco whieh may be quickly applied, the faces of the type being left clear by an equally simple procesa. The píate tlins preparcd is placed upon a cylinder arranged to revolve rapidly, so as to present oach letter to fiugers attached to tho traveliug frame. As the cylinder-bearing plate revolves the frame gradually advances by the operation of a screw and thus each and every line is succesively presentad to the fingere or inagnetic points mentioned. Ntctissarily the cirouit ia open whon the points are passing over a non-conducting surface, but as often as the metal type pressnts itself to said fingers the circuit is olosed and correspondiug inagnetic poiuts or pens at the receiving station make a record there in the same letter as the original, deüneating in a series of fine lines, either upon chemically prepared or órdinary paper, fixed upon a corresponding cylinder at the said receiving station.
