This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1905 edition. Excerpt: ... CHAPTER X TELEPHONE ACCESSORIES Taking the simplest case first, that of a line having one set of telephone instruments at each end, the accessories consist of call bells and switches, whereby, when the telephones are not in use, the connections with the battery are cut off so as to avoid the waste of battery materials which would ensue were the battery constantly to pour its cur rent through the circuit. This arrangement is shown in diagram in Figs. 17 and 18. When the telephone is not in use, the receiver rests upon a hook, which is normally held up by a spring, so that when the receiver is taken off and its weight removed from the hook the latter flies up to its upper position, closing the contacts 1 and 2, and opening the contact 3. This is the talking position. It will be noticed that the contacts 1 and 2, when closed, permit the battery to send its current through the transmitter and the primary winding of the induction coil. They also provide a path around the ringing mechanism, thereby taking the resistance of this apparatus out of the talking circuit. Through the construction of the ringing apparatus and bells their electrical resistance is necessarily high, and this method of bridging around them with a path of low resistance adds greatly to the efficiency of the telephone set. Referring now to Fig. 17, which represents the ap paratus with the receiver hanging on its hook, it will be seen that the path of an incoming current is through the ringing mechanism and the bell, thence by way of the hook and contact 3 out to the other side of the line. If the proper variety of current for bell ringing is sent out from the distant station it will be received and the bell will be rung; but this current, it will be noticed, does not go...
