- The'circumference ofthe ring 83 is not continuous, but is interrupted by insulating material 83, there being also a sudden drop,
- the circumference of the ring 84 is discontinuous, made so by the insulating material 84'.
- the rings 83 and 84 are in electrical communication with the shaft 85 from which leads the conductor 96 to one brush of the armature Ma of the motor M; the other brush connects by conductor 97 with one terminal of the series field winding Sf of the motor M, in parallel with which is connected the winding 80 of the brake lifting ma et.

- the switch 95 at the distant station being .on the contact 100, there is a circuit from the positive conductor through magnet 102 to contact 99 through lamp L, contact 100, switchlever 95, conductor 98, brake winding and field winding and motor commutator ring 83, brush 88 to conductor 92.
- the lam in such case will glow indicating that t e apparatus is in position to be motor operated to close the breaker.
- the motor then starts and rotates the. worm wheel until the crank 57 overtakesthe crank 56 which is .in" nearly uppermost position as described, and then presses against 43 downwardly to the position shown in Fi 1, in which position the circuit breaker 1s ring 83 at 837.
- the brush 89 haspassed onto insulation 84. So it is that the circuit breaker may be motor tripped from the'distantstation. Since a slight movement of the motor only is necessary for this purpose the circumferential extent of the commutator ring 84 need be relatively small only, as shown in Fig. 6, while the circumferential extent of the ring 83 may be correspondingly larger; As before stated when the parts assume full open circuit position the commutator has rotated soas to bring the ring 83 again in communication with the brush 88, whereu on moving the lever 95 to the contact 99 will cause the motor vto' again close the breaker. Care should be taken that brush 88 can not be in contact with ring 83 at the same time brush 89 is in contact with ring 84, else conductors 91 and 92 would be short circuited.

REMOTE CONTROL SYSTEM.
.T 0 all whom it may concern:
Be it known that 1, WILLIAM M. SooT'r, a citizen of the United States, reslding at Philadelphia, in the county of Ph ladelphia and State of Pennsylvania, have invented a new and useful Remote Control System, of which the following is a specification. 7
For an illustration of a form my invention may take reference is to be had to the accompanying drawings, in which:
Figure l'is a side elevat1onal view of the circuit breaker and its operating and control mechanism, a portion of the motor operated mechanism being omitted. Fig. 2 1s a front elevational view of the circuit breaker and its operating and co-ntrolmechanism. Fig. 3 is a front elevational view, partlyun section, of the joint between the connecting rod and the circuit breaker operat ng lever. Fig. 4'is a side view, partly 111560131011, of the connecting rod connection with the mo tor operated mechanism; Fig. 5 is a deta l View of the driving and driven cranks. Fig. 6 is a diagrammatic view of the control system.
Referring to said drawings, 1 represents a base of suitable insulating material such as slate, marble, or the like, upon which are secured the main circuit breaker contact limited movement upon the extension 17.
blocks'2 and 3 bridged by the laminated movable contact 4 secured to, but insulated from, thearm 5 pivoted at 6 to the bracket or housing 7, which is secured upon the base 1. v
, 8 and 9 are'the metallic and carbon movable shunt contacts respectively which co operate respectively with the stationaryme tallic. and carbon shunt contacts 10 and 11. The contacts 8 and 9 are carried'by but insulated from the-pivoted arm '5 which carries. the laminated contact 4. Pivoted at 12 in the'arm'5 is a roller13, which is engaged by the cam surface 14 on the cam member 15 pivoted to-the bracket 7 at 16. The cam meniberextendsoutwardly beyond the pivot 16 as shown at 17.' The operators handle or lever 18 is pivoted at 19 on the extension l7of the cam member and .is capable of The extent of movement is limited by the surfaces 20 and 21 as to a counter-clockwisemovement and by the surfaces 22 in a clockwise direction.

whose tail 24 is adapted, upon counterclockwise movement of the operators handle 18 upon the pivot 19, to strike the projec tion 25 of the latch 26 pivoted to the housin at 27, and engaging by its hook end the nected'to the armature of the reverse current or reverse energy tripping coils 34.
I Extending transversely through the oper- -ators lever 18 is a pin which fits within the metal bushing 36 within the insulating bushing 37, which; latter is secured within the eye 38 upon the rod 39. The insulating bushing 37 serves to insulate the rod 39, and the parts connected thereto below, from the operatorshandle and, in fact, from the entire circuit breaker. The rod 39 carries the transversely extending pin 40 which plays substantially vertically in the slot 41 in the bifurcated head 42 screw threaded upon the connecting rod or pitman 43. The rod 43 is screw threaded at itsvlower-endlinto the member 44 having extension 45. The extension 45 and plate are held together by the bolts 47, the separators 48 intervening. Approximate their lower ends, the extension 45 and plate 46 have spherical depressions or sockets adapted to embrace the ball 49 formed upon or securedupon'the crank'pin 50. This construction :forms a universal joint between the crank pin and the connecting rod 43, which, with the pin connection 40, obviates thene'ce'ssity for exact mechanical alinenient between the circuit breaker and the motor driven apparatus about to be described. I
he :crank pin 50 is common to the two-- cranks 51 and 52.' The crank 51 is secured upon the shaft 53 having a bearing 54 upon the base 55. On the other end of the shaft 53 is secured the crank 56 which is in the path of travel of the crank 57 secured upon lever 18 in an inwardly extending lug 23' bears upon the c'ommutator'ring or so the shaft 58 having the bearings 59 and 60 upon the base 55. Secured upon the shaft 58 between the bearings 59 and 60, is the worm wheel 61 which meshes with the worm 62 secured upon the shaft '63 of the electric motor M, mounted upon the base 64. The worm 62 terminates at its outer end in a conically socketed member 65, whose inner conical surface is the surface of what may betermed a brake wheel.
66 is a conically surfaced brake shoe pivo ted at 67 to the bifurcated lever 68 which is in turn pivoted at 69 to the base 55. The upper end of the lever 68 has a transversely extendin member 70 to whose ends 71 are connecte spiral springs 72 connected at their other ends to ears 73 upon opposite sides of the iron magnet jacket or housin 74, which is supported by brackets 75 and 76 upon the frame of the motor M. Within the acket 74 is a magnet core 77 pierced horizontally and axially to permit the passage of the rod 78 which presses with its outer end against the lever 68 and which is secured at its inner end to the armature 79 of the magnet, which is the brake lifting magnet whose winding 80 is dis osed between the core 77 and the insi e of the' jacket 74.
The inner end of the crank 52 is secured to the disk 81 of insulating material, such as hard fiber. That disk, with a similar disk 82 and the commutator rings or se merits 83 and 84, rotate, as driven by t e crank 52, upon the shaft 85 secured upon the plate 86, of slateor other suitable insubus bar or conductor 92 by the conductor 93 to the brush 88, which 'bears on cominutator' ring 83, and froin the conductor 91 by conductor 94, through the laminated brid e 4 of the circuit breaker such as shown in ig. 1. The generator G is connected across the conductors 91 and 92 when the circuit breaker is in'circuit closing osition. G is a generator, or other source 0 energy, or motor, or other translating device, whose connection with the conductors 91 and 92 is to be controlled both automatically by the circuit breaker and from a distance by the switch 95,as hereafter described. The conductor 94 connects also with the brush 89 which ent 84. The'circumference ofthe ring 83 is not continuous, but is interrupted by insulating material 83, there being also a sudden drop,
circuit, and similarly, the circumference of the ring 84 is discontinuous, made so by the insulating material 84'. The rings 83 and 84 are in electrical communication with the shaft 85 from which leads the conductor 96 to one brush of the armature Ma of the motor M; the other brush connects by conductor 97 with one terminal of the series field winding Sf of the motor M, in parallel with which is connected the winding 80 of the brake lifting ma et. The other terminal of the series fiel is joined by conductor 98,- which extends to the distant station from which the control is to be effected, to the switch 95, located at the distant control station. The switch member 95 is adapted to rest upon any one of the three contacts 99, 100, or 101, of which 99 may be connected to a positive conductor of the system through the windin of .underload magnet 102, while 101 ma connected to a ne ative'conductor o the system through t e winding of the underload magnet 103. L is an ordinary incandescent lamp connected between the contacts 99 and 100 to serve as an indicator.
The operation of the system and apparer ratus is as follows: With the circuit brea in circuit closing position, as shown in Figs. 1 and 2, upon the occurrence of an abnormal current flow through the circuit breaker, or upon the occurrence of reversed current or reversed energy fiow, the latch 26 will be actuated either by the armature 32 of the overload magnet or by the rod 33 of the reversed energy flow tripping mechanism, to release the member 17. Upon such release the sprin 15' will contract and rotate the cam mem r 15 in a counter-clockwise direction about its pivot 16, as viewed in Fi 1. The laminated contact member 4 will t en separate from the main terminal blocks 2 and 3, thereafter the metallic shunt contact 8 will separate from the metallic shunt contact 10, and finally the carbon 9 will separate from the carbon 11, and at these carbons the final a will occur-in the mannerwell understood 1n the circuit breaker art. As the cam member rotates, as described, about the pivot 16, the o rators handle 18 raises the connecting r 43 and rotates the cranks .51 and 52- to a position just short of dead center, just to the left of the uppermost 'tion they can take as viewed in Fig. 1.
t 0 revent reaching or passing the upper center, an extension 57 is provided on driv ing crank 57, and the lug 57? thereon extends into the path of'the driven crank, as seen in Fi 5. The generator or other do vice G has t on been cut oil by the opening of the-circuit breaker from communication with the bus bars'or conductors 91 and 92, and the crank'52 has rotated the commutator rings 83 and 84 to such position that the brush 88 has again come into contact with armature, through conductor 96, through 5 crank 56, driving crank 51 and pulling the rod 7 locked and the brush 88 has snapped off the the commutator ring 83 after traversing the insulation 86. The switch 95, at the distant station being .on the contact 100, there is a circuit from the positive conductor through magnet 102 to contact 99 through lamp L, contact 100, switchlever 95, conductor 98, brake winding and field winding and motor commutator ring 83, brush 88 to conductor 92. The lam in such case will glow indicating that t e apparatus is in position to be motor operated to close the breaker. The operator thenthrows the switch 95 onto contact 99, the armature IOtbeing held by magnet 102, whereupon the motor field and armature will be energized, as will also the brake magnet, which causes its armature 79 to be attracted and to thrust upon the rod 7 8 to lift the brake 'sho'e 66 carried by the lever 68. The motor then starts and rotates the. worm wheel until the crank 57 overtakesthe crank 56 which is .in" nearly uppermost position as described, and then presses against 43 downwardly to the position shown in Fi 1, in which position the circuit breaker 1s ring 83 at 837. This opens the motor circuit and deenergizes the brake magnet, whereupon the sprin s 72 set the brake and stop the motor wit the parts in position as shown in Fig. 1. Simultaneously, magnet: 102 releases armature 104, and switch arm; 95 returns to contact 100 under influence of centering springs 106 and 107. The apparatus is then ready to respond automatically again to the circuit breaker tripping magnets as just described. Or if it is desired to trip the. circuit breaker from the distant station, the operator will throw the lever 95. into engagement with contact 101, where-' upon current will flow from the positive; 'c onduc to r or bus bar 91through conductor i 94 to brush 89, commutator ring 84, con-i ductor 96, ener i'zin the motor, a'rmaturei and field as be ore escribed and the brake i lifting magnet, whereupon the motor will; rotate to drive the cranks 51 and 52 through I a short, distance in a clockwise direction from its position shown in Fig. 1, whereupon the 1 rod 43 is' lifted, the bottom of the slot 41 en aging thepin 40, thus lifting the operators ever 18, whereu on the lug 23 engages by its tail24 upon t e lip 25 of the latch 26"t'o disenga e or unlock the circuit breaker which t en opens as previously described, the extent of movement of the handle 18 with respect to member 17 being-limited by i its face 21 coming into contact with the face 20 on the member 17. After being thus unlocked, the circuit breaker then moves to full open osition, the o erators handle being pulle upwardly, pul ing the rod 43'with it and the parts assume the open circuit position with the crank 52 just short of the dead center position at the to as previously described in connection wit Fig.1. The brush 89 haspassed onto insulation 84. So it is that the circuit breaker may be motor tripped from the'distantstation. Since a slight movement of the motor only is necessary for this purpose the circumferential extent of the commutator ring 84 need be relatively small only, as shown in Fig. 6, while the circumferential extent of the ring 83 may be correspondingly larger; As before stated when the parts assume full open circuit position the commutator has rotated soas to bring the ring 83 again in communication with the brush 88, whereu on moving the lever 95 to the contact 99 will cause the motor vto' again close the breaker. Care should be taken that brush 88 can not be in contact with ring 83 at the same time brush 89 is in contact with ring 84, else conductors 91 and 92 would be short circuited.
