To all whom it may concern: I
Be it known that I, PATRICK B. DELANY, a citizen of the United States, residing at South Orange, county of Essex, State of New Jersey, and at Nantucket, county of Nantucket, State of Massachusetts, have invented a certain new and useful Improvement in Automatic Telegraphy, of which the following is a specification.
This invention relates to automatic telegraph reeeiving devices.
In the accompanying drawings: Figure i l is a perspective view: and Fig. 2,a 'vertical central section.
The receiving drum m has circumferentially and centrally thereof an inset band n of insulating material. The receiving stylus f opposite this insulating band is to bear upon the chemically prepared receiving tape that will travel in contact with the peripheral face of the drum,.that is with its peripheral surfaces m at and n. The drum may be connected to earth orreturn circuit by a brush b bearing upon one of the side faces of the drum.
This application is a division of my application, No. 469,804, filed December 29, 1908,
Iclaimz. An automatic telegraph recorder com.- prising a contact drum having a circumerential groove, a band of insulating material seated in the groove and a recording finger located opposite the band of insulating material and between which and the peripheral surface of the drum the chemically prepared receiving tape is to pass.
In testimony whereof, I have hereunto subscribed my name.
