is a specification.

My intention relatesrto electrical switches and has for part of its objects the provision cfa, simple, durable'and practicable switch especially adapted for'maintaining connections between a plurality of circuits andtor reversely connecting the conductors ot circuits responsive to the' electrical condition `of part of said circuits.'

vVarious other objectsand advantages will more clearly appear from the detail descript-iongiven below taken in connection with fthe accompanying drawings.

' In the drawings Figure 1 is a Vertical side "View of switch mechanism embodying. one

form of my intention. Fig. 2y is a -bottom plan View of the switch mechanism shown in 2'5- F ig. l. Fig.. 3 is a' vertical end View of the same. Fig. 4 1s aL diagramnixatical View 'showing the connections of my switch mech-` anism when its parts are in a normal or 1noperative position. 'Fig 5 isa similar View 'showing the connections when the parts are in operative position, and Fig. 6 is a similar View to that Yof Fig. 5, but showingparts and conductors reversely connected.

In all the figures like reference characters indicate like parts.

' Referringrto Figs. vl, 2 and 3 and especially to Fig.y l, reference characters 1, 2

and-3 represent three coils wound about'the irdn cores 5, 6 and 7 and forming electromagnets.. .These coils or electromagnets .are l secured atone end to an iron bridge piece 4 by means of nutsS.- At the other end 'of said electromagnets and secured thereto by heads on the cores 5, 6 and 7, is aplate 'or bar'9. The bar 9 carriesI four binding posts 1 0 which pass through said bar andaresecured to and electrically connected with four. terminals or contact posts 11,' 12,` 13

and 14. -These binding and contact posts are insulated from the bar 9 4by means of' mica or rubber as indicated atl. Projecting from'the sides ofthe plate or bar 9 in term'ediate its ends'are" ears 16 .and ,pivoted thereto by .means of screws or bolts 17 is a 24 and 25 are contact 'points' or pins 28,

magnet-izable bar 18. The bar 18 extends V over the poles of the

elcctrfnnagnets

1, 2 and 3, the electromagnet 2 being substantially at its center. v

Secured 4upon-the bar 18 by means of screws .19l are conducting and connecting' guide blocks 20 ,and"21 which are provided with vertically projecting flanges 'between which are pivoted the

arms

22, 23, 24fand 25. The guide blocks 2O and 21 areinsulated from each other and from the bar 13 by means otmi'ca or rubber 2G and the arms 22. 2", 24 and 25 are pivoted on pins 27.

Carried on the outer ends of the

arms

22, 23,

29 30 and 31 and at the otherend of said arms are vertical projections 32, 33, 34and 35'. Between the projections 32 and 33 is a' coiled spring 3G and between the projections 34 and 35 is a similar coiled spring 37. These -coiledsprings tend to force theprojections 32 and 33 andf34 and 35'apart and Athe contact point-s 23, 29, 30, and 31 against the contact posts 11,' 12, 13-and 14 respectively.

4In order to preventinjurious sparking the contact posts 11, 1213 and 14 have carbon blocks -38 in their ends to contact with the contact points 23, 29, 30a-nd 31.

At the sides ofthe guide blocks20 and21 are binding screws 39 and 40 for securingconductors thereto. 'Ihe plate 9 and bar 4 'are also provided with lugs 4 1. by means of` which the whole mechanism may 'be secured to a' switchboard or other suitable support.

`Then the electromagnet 1 attractsthe bar or magnetizable member 18 it willeassume Vthe position shown in dotted lines in Fig. 1,

the contact points 29 .and 31 bei-ng forced away from the 'contact posts 12 and 14 and breaking contact therewith. The springs 36 and 37, however, still maintain the `

contact points

28 and 30`incont-act with the posts 11- and 13. lVhen the el'ect-romagnetj3 attracts the member 18 the reverse opcrations take j place.

In order tions o the switch maybe more'clearly un ders'tood I have shown 1n Figs. 4, 5 and 6 the switch'connectedto a enerator 42, having a field 43, and an auxiliary or .exciting gen- Aerator '44. The auxiliary generator 44 y1s provided'tvith a'eld/l-energizetl by a batteryv 46.

The armature of the .generator 42 1s 'conthat the connectionsl and opera-- I nected in series with the coils of electromag# nets 1- and 3 and i h the binding screws 39 and 40. The con act 'posts' or conductors 11 and 14 are permanently connected by a conductor 47 andv the contact posts or conductors 12 and 13 are permanent1y..connect ed by a conductor 48. The 'eld' 43 of genbridging conductor 47. while the other end erator' 42' is connected in circuit in series with the armature of auxiliary generator 44 4and coil 2 and one end of said circuit is connected to the contacts 11 and 14 by the of said circuit is connected to the contact posts 12 and 13 by' bridging conductor 48.

If both of the generators 42 a1 1d 44abe'v Vdriven `from the same shaft, then, with the 'arrangement above described, the generator f 42 willalways 'deliver a current in the same.

direction regardless of the direction of its rotation. Such anarrangement is important in car lighting systems `in which the gener'ator is driven 'from the axle of a car.

'Wh'enthe generators 42 and 44 are at rest "-theco'nnectionswill be as shown in Fig. 4.1 '251 electromagnets 1, 2 and 3and the springs 36 fand 37 will'maintain contact points 28, 29, 30'

No'current will pass throughthe coils of the and 31in` connectiony with contact posts 11,

'. 12, 13 and 14. If then, the generators be in the direction shown by the arrows. whichA given rotation 'in ajclockwise direction the auxiliary generator44 4will deliver a current willl excite the field 43 and at the Sametime energize the electromagnet 2 and roduce a south pole at its lower end. As t e coils 1 and 3 areat this period connected'directly acro'ss'the generator 42 this latter will byV reason of its excitation, circulate a currentv j of considerable'fmaintenance through4 the bar l18 and the magnet 3 willrepulse it.V AsV .coils 1 and. 3' in a direction indicated bythe arrows, producingy poles as indicated bythe letterslN and S. VWith the condition of things shown inFig. 4, the electromagnet 2 produces a'south pole at the extremities of bar18so that the magnet 1 will'A attract the Asoon as the magnetizing currents reach a great enough" value the switch connections- -fassume the' position and conditionshown '1n' Fig; 5. A y

As shown in Figx 5, the generator-42 is connected in series with-theauxiliary or excitinggenerator 44 and in such a manner that the current-in field 43 is in-such a direction as tomaintain the polarity of the generat or42,.the same as when the condition of things were as shown in Fig. 4. -The 'direction of the `currentsis as shownV by the arrows and the, generator 42 connected to aid generator '44 in exciting the field 43.

The current from the auxiliary generator 44 may be'tra'ced `from the positive pole there,- o, through electromagnet v2, conductor '47, contact post 11, contact point 428, arm 22, binding screw 39, electromagnets 3 and l,

generator 42, fbind'tg screw 40t'm 24, contactpoint '30, tpfpost 13,A and field 43 back to th'cexc nerator '44..If, however, the generat" .42- a.nd 44.' are given rotation in a counter-.clockwise direction (see Fig.

6) the generator 44 will deliver a current inf the opposite direction and a north ypole will be produced at thelower end of the. electromagnet 2. The ba'r 18 then becomes oppositely polarized 'causing' the electromagnet 3 to attract it andthe magnet 1 to repulse it.

This causes the

contactpoints

28 and 30 to break contact with the Contact posts 11. and

13 but still-maintains the contact' points 294 and 31 in contact with the contact posts 12 and 14 The current from excitinggenera' tor 44'now passes from the V'opposite but' positive brush through the field 43 in the op# 4posite direction, through post.30, conductor' .48, post 12, point' 29, arm 23, screwl 39,

electromagnets

3 and 1, through generator 42'in the same direction as before, through screw 440,.ar m 25, point 31,p ost 14, conductor 47,

electromagnet 2 in the opposite direction and back to the auxiliary generator.' Since the field of generator 42 has been reversedand its. direction of rotation reversed it 'will produce an electomotive force-in the same direction as before and-will vaid the generator-44. Y i The electromagnet -2 'magnetizes and so polari'zes'the member or bar 18 as to. caus e it to 'be attracted Aby the magnet 1 or 4the magnet 3 accordin'g'to' the direction of lcurrent in the coil of saidmagnet 2 Vand field c43.

1 The switch is simple-,easy o f con-struction,

strong, and practicable in everyygayf-L It is` evident from the above description ";t,hat' it' is especially 'adapted for reversing' the cur- 'rent in a plurality of conductors responsive to the current in certain'of those conductors.

But, I donot vdesire to beilimited by the'-l special arrangementand. construction shown and described since .the switch 'may wellbe" adapted to other purpose'sandniany changes'4 and modifications maybe made therein 'withoutdeparting from the scope andspir'itxof ,my invention.
