To @ZZ whom 1,1; may concern: Be it known that I, 'Davila citizen of the United States, r

cago, in the county of Cook and o Witsen, a at Ch1- sate oir Illinois, have invented a certain and .useful Improvement in Telephone Apparatus, of which the following is a speciiication.

My invention relates to telephone apparatus, and has for its object to provide a new and improved construction of this description.

Myinvention is illustrated in the accompanying drawings, wherein- Figure 1 1s a plan View of a combined inductlon-coil and receiver embodying my invention. Fig, 2 is a section on line 2 2 of Fig. 1. Fig. 3 is a section on line 3 3 ci Fig.

two ends are brought into proximity to each other, said ends being separated'by the space A. (See Figs. 1 and 3.) This core is provided with suitable coils B and C of any suit able description. As herein shown, each of these coils has a primary winding and a secondar winding. The core oi the inductioncoil w en laminated maybe made up in any desired manner. As herein shown, it is made ulp of alternate layers, each consisting of t ree pieces, one layer, ior example, consistirig of the three pieces A2, A, and A". (Sh own in Figs. 5 and 8.) T he lower ends of the pieces A2 and A3 rest upon the top ed ge of A". The next layer will be made up olf the pieces A5, A, and A7, (shown in Figs. 6 and 9,) the piece A7 fitting in between the lower ends ol' the pieces A5 and A, Each of the pieces A, A, A, and i have the projecting pole-pieces D and D. When the coil is entirely pulled up with the coils in position and itis made iu these separable pieces, so that the coils can be properly placed, a combined frame consisting of' the pieces E and it", Figs. 7 and 10, is fastened to each side ol' the core, the 'whole being bound. together by bolts or rods or the like passing through the holes at the corners. Thdparts E and E are of non-magnetic ma terial, and they of course might be dispensed With. A telephone-receiver is associated with the pole-pieces l) and D', as shown in Fig. 3, yso that the diaphragm thcreol' is actuated by these pole-pieces. The pole-pieces may be used alone, or they may he provided with the coils DE and i233, connected in circuit with the secondary coil el the transl'o ner, The receiver may be oi any of the ordinary constructions and may he provided with. an earpiece l, connected thereto in any suitable manner, as by a liexibie tube it". Asso-- ciated with the inductioibcoil is a springcontact G, which extends over the opening formed between the opposed ends ol' the core, said contact being connected with bindingn post G', by means of W` ch it is connected in circuit. A coperati contact G2 assoW ciated therewith and corniected wit an arm G3, attached, to the core by the insuiating0- piece G4, saidarm being connected ii; circuit,

by means oi the conductor G in Fig. 4r have shown 'if coil conected in circuit with the tiansmi H ad a source of electric supply H, being a circ.lit-controlling switch H2 :tor cutting the transmitter in and out ci' circuit. There is also a ringing-switch H5. l/Vhen it is desired to ring up, the ringing-switch H5 closed, This completes thc circuit through the primary coil, so as to enc-rice itscore. 'lhc spring-contact G is then attracted to break the circuit at the Contact t. The coro is then deniagnetized and@ thc sprllig-contact released, so as to again complete the circuit. The impulse is thus sont out over the line through the secondary coil, so as to ring the bell or signal device at the other end, corresponding to the signaling device l. (illustrated in Fig. et.) This signaling device is ceunected across the main line, and the circuit therethrough is controlled by contacts associated with the controlling-switch H2, so that when the receiver is in position the circuit is completed and when the vreceiver' is rcinoved the controlling-switch is moved so as to open the circuit. The various contacts connected with the controlling-switch H2 are insulated from each other in any suitable manner. This continues until the switch ll5 is opened.

IOO

When the part H2 is moved op, so that the contacts H3 oud H" are together, the trans-- mittel' is in circuit. The ringing-switch H5 and the spring-contact or circuit-breaker G are connected in porofilrel withthc transmitter. it will he seen that i 4'inve here e (mostruotion wherein on inditerroir-coil, o, telephonercceiver, on d o signaling circuit :risking :md breaking device combined 'n o singio iostrurient and actuated trom t oustruo necessary for the induction-coil clone.
