Description

of the line bars 10 is controlled by moans ot an electroniagnet. 30, the. energization of whieh moves an armature 31 inwardly. The armature ill is iu engagement with a iiv otal extension ot a line bar Il), and as it is moved inwardly, moves the assoeiated line har It) long-itluliually` and a roller 32 mounted on the side oli said bar at the opposite end thereof engages a ram projection 33 mounted on the inner t'aee ol the eml plate opposite to that earrying the magnet rontrolling; a particular bar. The engagement of this roller 25:. with its eorrespomlimgr cam surtaee 38 causes au angular displaeement of the bar 10 against the tension of a spring lll. When one ol' the bars 1() is thus displaeed, a Set of the eontaets 12, 13 and 14 will be brought into engagement with a eorrespondingr set. of eontaets T. 8 and tt on the displaced trunk bar. 'l`he trunk bar with its terminals thus engaged will he released t'rom its displared position and rot-ate to the right to earmv its uneugaged terminals out of msition to be engaged by eontaets of anot )er line bar` whieh may be snlisepienily operated while a eireuit is eonnerted through terminals of that. partieular bar.

The eyele ot' operation for the deviee of this invention is practically the same as that described in the lateut No. 1,131,734 and, without traeing in detail the eireuit ronditions` is brietiy as follows. At all times one, ot the trunk bars .3 will be. in a displaced position. ow upon the initiation olI a eall one. of the. line. bars 10 will be displaeed longitudinally and angularly by the magnet $5() to bring a set. ot' eoutaels .thereon into engagement with a set ol' eo'ntaets on the displaeed trunk har 5. 'l'he longitudinal movement oll the bar ll is sullieient to earry the uneugaged terminals thereon beyond a position where they ran be engaged by the terminals of subserpieutly displaeed trunk bars while the particular line bar is in use. 'lheengagementot` the terminals l2, ttt and 14 of.the lim` bar l't with the termimils 7. R and t) of the trunk bar operates to edel-t. a eomplet ion ol' the eireuit lor the trip mag net. 2S individual to the truuk bar` whereby the bar is released and returned to normal position where'itsI unengaged terminalsI are outl ol` a position to he engaged b termiY mils ol` others ol the lilubars 5 whieh may bo lsuhsmpleutly o|araled. 'lhe operation ot' the tr'ip magnet .S eompletes a eil-enit I'or a relay ttl whieh eompletes a eireuit tluouglrthe setl magnet 23. to eause the longitlu'liual moveluent of the sha ft 2.0 to setl another trunk bar 5.1,; As the shaftflt returns to normal positionl a eiljeuitis eompleted for a 'relay il whieli eontrols an interrupter meehanism IJ in eirruit with the. magnet. 'il-t. This cansesfimlgnet. il to` operate and rotate, the shaft. 21') to brin n pin or projection 21 thereon into position to engage the lever 22 of an idle trunk bar 5 upon the next. longitudinal movement of the set shaft Q0.

The terminal eontaets T, 8 and 9 n )on one side. of. the trunk bars 5 will be dis i :iced in opposite direetions upon the disp acement ot' the trunk bar, and the line vbars upon opposite sides ofthe trunk bars will be moved m opposite di|eetious--tl1ose upon theI front, as shown in die drawimg` being moved tothe. left, while those upon the haelt are moved to the right. Magnets for moving those shown in tlie bark will be mounted upon the e'nd plate 2 in the same annuler as those upon the end plate l.

By reason of the eonstruetion whereby the trunk bars are provided with terminals on eaeh side, the, same number of trunk terminuls ean be provided on a bar half the lengt-h formerly used` and by mounting the line bars upon both sides of these trunk bars and lorating eontrolling meeha-nism therefor upon eaeh end ot' the apparatus. a structure of the `same line and trunk eapaeity can be obtained with a nmrh smallelnd more compact strueture than eould be obtained with that diselosed in the lateut-No. 1,131,734.
