T 0 all wiz-0m t may concern.'

Be it known that we, VILLIAM il. Sr- Aions and LAURENCE M. KLannnn, citizens ot' the United States, residing' in 'the city ot' New York, State of New York, and in the city of San Diego, county of San Diego, California, respectively, have invented new and use'liul Improvements in Remote-Controlled Switches for High-Tension Trans mission-Lines, oit' which the following is specification. y

This invention relates to switches, and it is especially applicable to the switches employed on high-tension transmission lines..

The general object i the invention is to provide simple means for effecting the opening and closing ot the switch `trom a distance. To accomplish this we provide a. very simple motive torce for moving the switch, which will effect the movement of the switch, and which will cooperate with simple and reliable means for positively controlling the operation of this motive 'orce from a distance.

The invention consists in the novel features, and inthe general combination of parts to be particularly described herein after, all of which contribute to produce a simple and eiiicient remote-controlled switch for high-tension transmission lines. I A preerred embodiment ot our invention will be particularly described in the Vfollowing specification, while thebroad scopeot ourpointed out in the appendj invention will be ed claims.

In the drawing, c Figure 1 is Va vertical section' through an apparatus embodying our invention, the switch proper, however, being indicated diagrammatically; and

Fig. 2 is a fragmentary view further illustrating the mode of operation of the apparatus. y Y The controllingparts of the apparatus are most conveniently housed withina bor` l, which, it desired, may have a lid 2, hinge at 3, so as to give access to the interior or" the box. This boX may be attached to the side of a'pole Il, carryinga transmission line or lines indicated by the conductors 5 and 6, between which there is located the switch which may include amovable switch-member or lever 7, the pivot 8 whereof being connected with the line-wire 6, the other end ot the lever cooperating with a contact 9 connected with the line-wire We provide a rotatable member which may consist or a simple wheel 10 rotatably mounted on the side of the box 1, and this member connected by suitable means with the lever 7, in such a way that when the ro- -tat-able member or wheel l0 rotates, it will hold the switch alternately open and closed. The means illustrated for connecting the wheel and the switch lever, consists oi a link 11 which is pivotally attached to the switchlever 7, and similarly attached by a pivot connection 12 to the wheel. i

ille provide Vmeans tending to rotate this rotatable member or wheel and we also provide means for holding the wheel in two positions, in one of which, as illustrated in Fig. 1, the pivot connection 12, is disposed adiacent to the switch-lever; the other position of the wheel is substantially diametricallv opposite to that illustrated, in which case the pivot connection 12 would lie remote from the switch. y

AAmy suitable means may be provided which will tend to rotate the wheel. This may consist simply of a cable or chain 13 which passes around the periphery of the wheel, it being understood that the wheel is held in a vertical plane. On this chain we provide a detachable weight le which tends to rotate the wheel in the direction indicated by the arrow in F ig. 1. `We provide nea-fis cooperating with the wheel which ops to permit the weight to descend, and

me t ie weight descends it produces a ln other Cooperating with these stops we provide` ay detent-mechanism which is controlled trom a distance preferably by an electric circuit or circuits whichmay be closed by a push tent-mechanism is coperating with the stop ythe depending arm19 toward the left.

swinging movement would eventually swing 15 to detain the wheel 10 in a position Vto maintain a switch in its open position.

Coperating with the stop 15 we provide a detent 17 having artoe 18 anda depending arm 19, both rigidlyattached to a4 pivot or stub-shaft 20, so that. the detent is freely movable. A similar detent, but ina reverse position is provided opposite tothe detent 17, that is to say, its toe 21 projects toward the left instead of toward the right, and this toe 21'is in the path of the stop 16.

Associated'with each detent we provide a coil-spring 22, and these springs tend'to hold the detents Aprojecting into the paths of the stops l15 and 16. VVln the operation of the device, when the stop 15 comes against the toe 18, it rocks the Vpivot 2Oy and swings This the detent away Vand cause it to Withdraw from the path of the stop which would per- `mit the stop to pass, but such a complete Vmovement 1s prevented by means of a 'trigger 23 which has a pawl 24 to engage a notch in the lower end ofl the arm 19. This trigger 23 is pivoted at 25 and we provide lelectrical means 'for controlling it to disengage it when desired. For this pury pose, we prefer to provide an electro-magnet in the form of a double solenoid 26 having a dou-ble core 27 pivotallyV attached at 28 to the lower end'of the trigger. The coils of the solenoid'26 are connected in an electric c1rcu1t passing through conductors 29a and 29'), andwhen this circuit is closed at a remote point by'meansl of a switch or pushbutton, the core 27 is attracted and the trigger 23 is rocked in a clockwise direction about the pivot25. `Fig. 2 'shows therelation of the parts at such a time,rand indicates the manner in which the motive force of the weight 14 will operaterthrough the stop 15 to push the toe 18 out otits path Vso as to permit the stop to pass.

tion of the wheel 10 will continue until theV substantially diametrically opposite stop 16 comes against theV toe 21 of the right hand detent, whereupon this detent will berocked in an anti-clockwise direction until the lower end of this detent arm 30 comes against the end of a` pawl 31, similar to the pawl 24 and formingy a part of the right hand trigger 32. Y

Between the arms 19 and 30, we provide means such asa bar 33 `for limiting the movement of theV detents by their springs.

TheV rota- Y The triggerV 32 is controlled by a solenoid 34 similar to the solenoid 26, which is enervwill now be briefly stated In the position shown in Fig. 1, the actionV of the weight 14 tends to rotate the wheel 10 in theY directionindicated by the arrow, that is to say, the weight holds the stop 15 against the'toe 18 of the' detent 17. However, the-detent cannot swing out of the way to permit the stop to Vpass onv account of the pawl 24 ofthe trigger 23 g however, when it is desired to close* the switch 7, this is accomplished simply by closing the circuit Vthrough the conductors29a and 29b and the Vsolenoid 26, whereupon the solenoid rotates or rocks the trigger 23 in a clockwise direction, thereby disengaging the p'awl 24 from The triggers 23 and'32 are Vpref- I the arm 19. This permits the'arm to swing towardthe left, (see Fig. 2),.therebypermitting the stop 15 to pass. Thewheel then Y rotates through a half-revolution, that isto say, it rotates until its rotation is arrested by the stop16 striking the toe 21 of the' right hand detent. Vhen this occurs, the shock of the contact is takenup somewhat by the corresponding detent spring 22 which becomes extended asV the arm 30 swings toward Vthe right until it engages the end of the pawl 31. VThis will hold the wheel 1() in a position to maintain the switchclosed, Vand the switch will vremain closed untilgthe elevated point.

Y It will be observed that the mechanism ofV this apparatus is very simple and' not likely 4 to get out of order. It is also evident thatV in the present instance the electric current is not employed torprovide the motive force for actuating the switch, but simply conp trols the motive force which opens and closes the switch at the will of the operator.

It is understood that the embodiment ofl the invention described herein is only one of the many embodiments our invention mayvr takel and we do not wishV to be limited in the practice of our invention nor in our laoV claims, to the particular embodiment set forth. f
