Application fled November 18,1925. Serial 1.. 5,815..
My invention relates in general to relay systems as used in telegraph systems and pertains specifically to a novel type ofpolar or polarized relay and associated circuits I and a aratus, particularly adapted to function e ciently in systems utilizing operating impulses of short duration.
The principal objects "ontemplated by my invention com rise producing a relay sys-'- tem in which t e tongue or armature is firm- 1y heldagainst a selected contact during riods of no current in the operating Windlugs and in which weak or momentary opcrating impulses are compensated to effect positive operation of the tongue. I
I accomplish these and other features which will hereinafter be discussed by providing additional windings and associated circuits and apparatus. as shown in the drawing accompanying and forming a part of this specification. In the drawin I one em iment of my invention in con unction with a regenerative telegraph repeater.
Referring now to the drawing, the o erating winding of the. receiving rela R is operatively connected to a line E and ground. Current supply of o posite polarities is rovided by the groun ed generators G and 5 as shown. The tongue T of the relay is connected to the continuous contact bar SRof a distributor D, the contacts A of which are connected together and to ground through the operating winding W of the an transmittingrelay TR. The apparatus described is a diagrammatic representation of the essentials of a regenerative re eater utilizing polarized relays of the eatstone type and in which, as the brush BR traverses the-contacts A in synchronism with the si I als received over line LE, the tongue T o relay RE is momentarily connected through the contacts A to the operating winding IV of rela TR, to transmit curi or G to relay TB.
portion of the received and retransmitted. The ration o the impulses is determined b the size of the segreferab y these are made as small as possi la in order that badly distorted received signals may be successfully repeated. Such organizations as the above are common in the art, and it is not con- 6 sidered necessary to further discuss them 'tr'emity of windin ointed out and ave illustrated diagrammatically tive contact there wil be a rush of current er al is an mented' here. It-is-obvious that the use of such extremely short impulses while being advantageous in reconstructing badly distorted received signals, may, due to the short duration thereof, fail to properly operate the transmitting-relay. If the relay is adjusted to respond readily and reliabl to such impulses the holdingbias may e insufiicient to keep the tongue in positive contact with its contact points at moments when no current is traversin the operating winding. To overcome this defect I provide additional windings W and W on relayTR one ter- 1 minlal of each of which is connected to ground through a resistance R. The remaining ex- W is connected 1 with the tongue T? through a resistance of the relay, while the remaining terminal of winding W is connected through condenser C to ground. Thus when T is resting against its positive contact a small current will flow from Gr through R, W and to ground through R. The windingsare so connected that this steady flow through W will be in such direction as to hold T firmly against the ositive contact and thus while bein smal in value due to the resistance o eredby R and R will be sufficient to prevent the tongue from being jarred away from itscontact. No current will flow through W, 'but obviousl condenser C will be maintained in a c arged condition due to the potential of generator G. When a short current impulse to oper ate the relay passes through W it will cause tive contact and. when T, breaks contact the current through R and W which was opposing the motion of the tongue will cease to flow and the condenser C will dischar through W? and R to ground to assist e operating impulse through W in bringing the tongue T 2 over against the negative contact. When, the ten e touches the nega-' through W to charge condenser C in the opposite directionor polarity to its revious c arge, and this rush of current wi tend to hold T' a ainst its contact toprevent chat,- tering an insure a positive contact. After condenser C has become charged to the full potential supplied by generator G there will continue a small current flow from v G" through T; B, W and R to ground and this steady current of small value will tain the tongue T firmly against the nega tive contact. When the direction of the operating impulse through W is such as to kick the tongue T from the negative contact the action just described will again take place except that obviously the direction of current flow in the auxiliary windings will be reversed.
This auxiliary holding and accelerating relay system just described makes it unnecessary for the impulse through the operating winding W to move the tongue all the way from one contact to' the other. The impulse W may be only'sufiicient to initiate the movement and the current through the auxiliary windings complete the work'of carrying the ton e across the gap, and thereafter hold it r mly in contact.
It is obvious that the application of this invention is not limited to use as a transmitting relay in connection withcre enerative repeaters. It may be used anyw ere it is found necessary to efliciently and reliably operate a relayby impulses of very short duration.

1. In a relay system, a relay provided with a tongue, contacts therefore and an operating winding, a pair of windings independent of said operating winding, means ,for utilizing one of said windings to hold said tongue against either of said contacts and means for utilizing the other of said windings to assist said operating winding in moving said tongue from one contact to the other.
2. A relay system comprising in combination, a polar relay'provided with a ton e, contacts therefore, and an operating winding, an auxiliary winding independent of said 0 crating winding, means for utilizing a portion of said auxiliary winding to hold said tongue against either of said contacts and means for utilizing another portion of said auxiliary winding to assist said operating winding in moving said tongue from'one contact to another.
