Abstract: 17,093. Herman, J. Aug. 23. No Patent granted (Sealing fee not paid). Current and energy meters.-Permanent magnets and solenoids for ammeters, volt-meters, and wattmeters are constructed in such a way that the range of movement of the moving element amounts to more than 300 degrees. The magnet shown in Fig. 10, intended for a moving-coil instrument, has concentric and nearly circular pole-pieces b, c, attached to opposite sides of a horseshoe a; a similar magnet with pole-pieces of the same size, placed in parallel planes, is described. For moving- magnet instruments, the form shown in Fig. 4 is adopted, the pole-pieces being arranged in parallel planes ; two such magnets may be mounted in opposite directions, one below the other. The magnets may be formed entirely of sheet metal, the pole-pieces of soft iron, and the horseshoe or corresponding part of steel, as in the example shown in Fig. 6, in which two parallel and almost complete soft-iron rings are connected by a short bent-up steel section a, cross-pieces l of non- magnetic material being added. Solenoids of the forms shown in Figs. 9 and 12 are used especially in alternating-current apparatus, the connecting- part a, Fig. 9, being inclined to facilitate winding. The interspace in both magnets and solenoids may be uniform or irregular according to the scale required. Specification No. 22,851, A.D. 1897, is referred to. The Provisional Specification describes several arrangements of magnets for use in suspended-coil mirror galvanometers. In one of these, a single horseshoe magnet is provided with approximately semicircular pole-pieces. In another form, for a single-coil or double-coil instrument, two or four horseshoe magnets are arranged parallel to one another, and their like poles are connected by yoke-pieces carrying curved polepieces. In another arrangement, two horseshoe magnets are placed opposite one another and are provided with curved pole-pieces one above the other. Another magnet for a suspended-coil instrument is curved and provided with inwardlyprojecting arms to which curved pole-pieces are attached. The Provisional Specification also describes alternating-current apparatus in which stationary coils act upon suspended soft-iron cores. A suitable form of core consists of two nearly complete rings of soft iron connected by a metal piece, the gaps being slightly displaced.

Patent GB-190620733-A (GB)
Title: Improvements relating to Conversation Counters in Telephone Installations.
Filed: 1906-09-18
Granted: 1907-06-13
Abstract: 20,733. Siemens Bros. & Co., [Siemens & Halske Akt.-Ges.]. Sept. 18. Telephone systems. -Counter mechanism for telephone systems is operated through two contacts, one of which is made or broken by the insertion of a plug by the operator on receipt of a call ; if contact is made, one terminal of the counter magnet coil is earthed ; if contact is broken, a short-circuit across its ends is interrupted. The other contact is closed either by the armature of the call magnet, or by a key under control of the exchange operator, and independent of the plug lead. In the arrangement shown in Fig. 1, the removal of the receiver by a subscriber A completes the circuit through the call magnets c, c', of which the effect of c predominates, attracting the armature h and completing the circuit of the indicator k. The operator then puts in a plug l, which first sends extra current by the course n, o, u, l, m, through the coil c' increasing its magnetic effect and restoring the armature h to its original position, and then, when driven home, makes a contact q which earths one end of the coilp of the counter magnet. The plug r connecting with the called subscriber is now inserted, and the counter operated by temporary depression of a key t in the circuit supplying adiitional current to the coil c<1>. The armature h is again attracted by the coil c and completes the circuit of the counter magnet, its other terminal being earthed. Possible failure of action owing to the subscribar A prematurely hanging up his receiver may be avoided by the insertion of a suitable resistance between the leads to the plug l, or by temporarily connecting these leads on depression of the key t. In one modification, the plug is made to break a contact in a connexion which short-circuits the magnet coil p. Hence the first movement of the arnature on to the contact produced by the call does not operate the counter ; but the secoud contact, after insertion of the plug and depression of the key t, does operate the counter. In each case, the counter is fitted with a " holding-on " coil p<1> to pravent further actuation of the counter by the key t. In a further modification, the key t is placed in the lead to the plug l, so that on depression extra current is supplied to the coil c<1> to return the armature to its normal position, this movement connecting one end of the coil p with the battery, the other end having been earthed by the contact q. Fig. 4 shows a system in which the counter circuit is independent of the call magnet. The contact q in the jack earths one end of the coil p of the magnet, which is energized by a separate battery g<1> on depression of a key t, holding "on" coils p<2> being provided as before. A num. ber of counters can by this means be operated simultaneously.
