e To all whom am concern:

Be it known that I, SIDNEY A. Bernese, acitlzen of the'Unite'd States, Lion Meadow, county of Monroe, and State o ew York, have invented certain new in Telephone Syste' s; and I do hereby declare the following to be a full, clear, tion of the invention, such as will enable others skilled tains'to make and use the same.

My invention relates to improvements in telephone systems-and has for one of its objects the provision of'means for releasing the ringing controllingmeans for further use, after the ringing connections has been completed. 4 I

Another object of my invention is to accomplish. the-above named object in connection with a paratus forautomaticall signaling a su scriber, and also for 'pl ar such means under the control of-thei calling switch.

Other objects of my invention will be clear t cul from a description of an embodiment of the Figure 1 shows diagrammatically an embodiment of myinvention.

Fig. 4 is athird modification of the em- .bodimentshown in Fig. 1.

Referring now to the drawings and to the my invention illustrated therein, and first to the embodiment shown in. Fig. 1 at A is shown a telephone line which wil be spokenof in this specification as-"the calledv line, leading from a plurality C. D and E.

trated in the drawing. Switching means, shown at H, are provided for connecting the cord to the telephone line. In thefiembodiments illustrated, this switching means consists of plugs and jacks, illustrated at p and J, respectively, in Fig. 1. sources of signaling current, hereshown as generators I, K, Land M, are employed for aerating the signals at the substations. in he signals at the substations may be so (3011-. structed that they respond tooneparticular character of currentonly,,;and the generators may be so constructed'that theywill select A plurality of and operate the signalsat the substations.

Conductors are provided for connecting the sources of current to the line. Commutators 4, 5, 6 and .7 maybe connected in these con-- doctors for'the purpose. of intermittently associating the sources with the signal so as to cause the operation of the signal at intervals of time. Signal at N, O, P and Q, here;illustrated asring- V the, connection of the sources, I, K, L and M A- master key or switch is shown at R, which .isoperated whenever any of the keys N, 0,1 or'Q. is operated. Relays are shown I X and Y. When it is desired to'connect the source M with the called line, the switchH' is operated by insorting the plug p into the jack J. 1 The key Q, is then operated, operating at the same time the key R and closing a relay through the contacts of the relay the contacts'of the key R and the contacts of the relay S, which was energized'when .the

The relay W will be energized, closing theswitch 9 and thereafter opening'theswitch 42 and interrupting'its connection with the conductor 43. Closing the switch 9. completes a locking circuit for the relay W from ground 44 through 9-the relay W and overt e circuit 'asprevious'lytracedP The relay" also opens switches 45, 4'6, 47 and 31, cqmpletely disconnectingthe bank of keys N, and R from thewcord circuit G, there-by releasing the keys for use in connection with another cord circuit, for example, cord circuit G. However,'if after the operation of the switch H the key Q, were operated, a circuit would be completed tor the relay Y and the source of c'urre'nt M would be connected to the line A in the same manner as described in connection with the cord G and the-lineA. If it is desired toope'rate the signal at G, thej'key P-is operated, thereby completing a circuit-forfthe relay V as follows: 1817-switch-23 V-switch 47-conductor 50-'conductor 51 key P to ground 28. energized, opening the switch 52 and disconnecting the source M' from theconductor 5'3 and closing a switch 54,'thereby connecting the generator I -.to the conductor '53.

The relay V also closes a lo'ckin'gcircuit for itself, by closing the switch 55, such locking circuit being from ground 56, through switch55' and the circuit for V, as previously traced. The closing of'the switch R will in the same manner cause the energi'zation'of the relays'W and Y and the operations with respect to theserelays will be the same as before. I

All three of these relays will be actuated, the relay 100 closing a switch and completing a self anrl closing a switch 131 in. the connections of the source Ma: The relay 101 closes a switch 132, completing a locking circuit 133, completing the connection of the source 134.

This relay alsocloses a switch 139 relay W which is en or 'zed from ground 136-switch 139- re ay W -'switch 141-to ground 110.

Whenit is desired to connect the generator L, inthe circuit, the key P, is, actuated, completing circuits for the relays 101. and Y,, through the switches and 161., respectively, and when it is desired to connect the source I, is operated, completing a circuit for Y through connected, the automatic ringing will be substantially the same as previously described, and the system will be restored: to the jack J therebyreconnecting the bank of keys to the cord circuit G,-. .7 In the embodiment shown in Fig. 2, it will be noted that no master key is employed,

It will also be noted that the circuit of the key disconnecting relay W, is completed by the relay Y, instead of being controlled by the master key.

When the conversation isfiterminated, the

circuit of the relay W will be broken when the relay S is deenergized which will'happen when its circuit is interrupted by the opening of the switch H thereby re-connecting the keys to generators 1 K and L may be selected and connected in the. ringing circuit instead of thegenerator 184,, through the operation of the keys N 0 and P and their control overthe relays T U and V In each case,'the circuit of the relay Y will be closed the cord circuit (3,.
