This inventionrelates to controlling mechanism for electrical switching apparatus; its objects are to increase the eifective operation of a series-of electrical devices, referred to herein as counting relays, in them control of a responsive device associated with the switching apparatus and simplify :the mechanism.

lation to a series of independently operable switches and a responsive device that a circuit for the latter is prepared simultaneously with that of the last one of a predetermined roup of electrical devices selected by one of t e series of switches. I r
In the embodiment of my invention shown herein, the responsive-device is in the form ofa relay and operates simultaneously with the last-oneof an selected group of electrical devices or so-cal ed counting relays.
The invention is useful more particularly i in the control of high speed selective switching apparatus for telephone exchange sysprises a series of electromagnets, which are operate successively in response to current impulses froman impulse transmitter or interrupter, and a series of keys or other suitable form of contact switches, one key or switch being associated and arranged with is actuated simultaneously withthe corresponding relay.. The impulse transmitter or interrupter is preferably in the form of asteppiug relay, the switch contacts of which alternately make and break a contact inthe circuit of the relays. The responsive device is employed as the means of stopping the'operation of the impulse transmitter and the selector. It may be in the form of an preferably relays and which are caused to each relay in such a manner that. upon the operation of any key a responsive device ordinary cut-off relay and its winding may be included a local circuit having a plu rality of'normally open branch circuits, each of which is adapted to be closed by a corresponding switch or key. A. second series of relays is preferably employed in conjunction with the series first mentioned and the two series of relays are associated with two docal circuits respectively. These local circuits are arranged to be closed alternately Joy the stepping rela-y,'the winding of which is included in a main controlling circuit which circuit is provided with some suitable form of contact making device or interrup- 'ter,,,operatiug in unison with or in the movement .of :the selector. 'Ihe relays in the two series which are operateddn alternate suc- .cession' are wlf-locking. The cutoff relay stops the operation of the interrupter and the movement of the selector preferably by l peu-ing the main controlling circuit.
I Referring now to the drawing, 1 is a main controlling circuit including the winding of contact 3 normally closed but adapted to be tems wherein the selector is continuously; driven by the application-of'power and a; controlling device intermittently operated by impulses transmitted to the controlling controlling device in turn operating the re- I device in the movement of the selector, the.
, sponsive device to stop the movement of the selector and to interrupt thev sending of impulses.
More in detail a type of mechanism in which my invention may be employed comopened by a cut-ofi relay 4. Relay 2 is adapted to alternately close andvinter'rupt two local circuits 5, 6 through its front and back contacts 7, 8, respectively.
Current is supplied to the local circuits 5 and 6 from batteries 5 and 6 through switches .5 and 6 which are closed during the operationof the counting relays. There are two series .of these counting relays, the first 10 to 17 inclusive being those fed by the local circuit 6 and the second 10 to 17 inclusive by the local circuit 5. The winding a stepping relay or interrupter 2 and a 24 to 31 inclusive each adapted to close a.
of the cut-oflf relay 4. is included in a circuit 23 having a series of switches or keys branch of the circuit 23 and thus energize the cut-off relay 4 simultaneously with a counting relay of the second series corres'ponding to the key depressed. In the drawingwhere is shown a. contact device 50 coperating with a starwheel 51- which is rotated in the advance movement of a con- "trolled automaticselector 52. This selector may be employed to perform any desired function in the telephone exchange system,
such as the selection of a connection between telephone lines. The advance movement,
\ closing of the circuit of the clutch magnet 57 the rotating disk 55 engages the normally stationary disk 56 which drives the starwheel 51.
periodically to closeand open a. shunt path about the stepping relay 2 in themain controlling circuit. This circuit is adapted to be closed initially by contacts 61, 62 when it is desired to start the selecting operation.
The operation of the controlling apparatus is as follows: Consider, for example, that it is desired to send three. impulses in order to'permit the selector to advance three steps. Switch 26 is closed and cont-acts. 61 and 62 are also closed to complete the controlling or fundamental circuit. Relays 58 and 2 are energized and the 'sele'ctor 52 begins its advance movement; The rotation of the starwhel 51 causes the current to be shunted from relay 2, once for each step. Relay 58, however, is not affected but remains energized. Upon the first closing of controlling circuit 1 relay 2 operates to rent from the same battery through its own switch spring or armature close local circuit 5 at contact 7, which cirpuit normally includes only the winding of relay 10. This relay is energized and becomes locked in a circuit upplied with cur- 60 instead of switch spring 9 of relay 2. Relay 1 0 also prepares a circuit from local circuit 6 through switch spring 70 for relay 10 and the latter becomes energized over this circuitupon the closing of contact 8.
when relay 2 is deenergized bythe closure of the shunt circuit at contact 50. Relay 10 m turn is locked up through a circuit supplied with current from the same battery 6 but grounded through its own' switch spring 80 instead of switch spring 90f 're-.
lay 2. Relay 10 inturn likewise prepares acircuit from local circuit 5 through switch Contact 50 is thus caused but grounded sure 0 local circuit 6 at contact 8. Relays 12 and 12 are in the same way operated in succession upon the third closin of local circuits 5 and 6, respectively. inally. simultaneously with the energization of relay 1 2, switch 26 being closed, relay 4 is energized since its local. circuit 23 leads to ground through the same contact 95 as the circuit of relay 12. The circuit of relay 4. being battery 4*, 4, 23, 26, 95, 92, 90, 70, 8, 9, ground and that of relay 12 being bat tery (r, 6* 6, 12, 95, 92, 90, 70,8, 9, ground. No delay is occasioned by waiting for relay 12to close, since not it, but the next to the lastcounting relay completes the circuit for the responsive device at the same instant that it completes a circuit for thelast counting relay. Consequently the opening of the fundameptalor maincircuit at contact 3 of relay 4 is accomplished the moment the last counting relay. is reached. Current is cut ofi immediately from stepping relay 2' and the sending of impulses ceases at once. i
steps. Relays 10, 10, 11, 11, 12, and 12 remain locked up until they are disconnected from batteries 5 and 6 by the openin of V switches 5 and 6 respectively. The w ole operation may be repeated'with any one of the keys depressed.
The serles of relays and keys may be vextended to any desired extent by continuing the circuit arrangement as shown to other .relays and keys.
What I claim is:
1. The cgmbination with a series of successively operable electrical devices, of means for. selecting a variable group of said devices, a responsive, device and means for preparing-a circuit for said responsive device simultaneously with the preparation of a circuit for the last one of said electrical means for said last named means responslve over a circuit prepared simultaneously with the circuit for the last one of said electrical devices in any predetermined group. p
