WILLIAM E. DAVIS, OF JERSEY OITY, NEW JERSEY.
IMPROVEMENT IN ELECTRO-MAGNETS FOR TELEGRAPHY.
Specification forming part of Letters Patent No. 133,5568, dated December 17, 1872.
To all whom it may concern:
Be it known that I, WILLIAM E. DAVIS, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Telegraphic Instrument, of which the-followin g is a specification:
Figure 1 is a side elevation, and Fig. 2 is a top View, of my improved telegraphic instrument.
Similar letters of reference indicate corresponding parts.
This invention relates to a combination of one electromagnetic coil and its magnets with two or more armature-levers which are simultaneously affected by the currents through the coil, thus utilizing the same electro-magnet for operating a suitable number of instruments at once.
In carrying the invention into effect I shape the magnets A and B at the ends of the coil 0 like crosses (see Fig. 2) or otherwise to obtain the desired extent and position of contact surfaces to I) cl 0 for the armatures D D D D &c., which areshown by dotted lines in Fig. 2. When a current is passed through the coil 0 and magnetizes the plates A B the armatures will all be attracted at once, and all will be repelled or withdrawn at the same time, if the current is arrested. By this means a suitable number of messages can be sent by one operation through several diverging lines, and more power will be derived from the same electro-magnet than could be done where but one armature was acted upon by the same coil.
This invention can be used in suitable position-vertical, horizontal, or otherwise-and with a continuous or divided coil.
Having thus described myinvention, I claim as new and desire to secure by Letters Patent- The combination of an electro magnet with two or more armatures which are simultane ously attracted by the same plates A B, as set forth.
WILLIAM E. DAVIS.
