ELECTRIC SWITCH.

Specification of Letters Patent.

Patented May 17, 1910.

Application filed June 3, 1909. Serial No. 500,008.

To all whom it may concern:

Be it known that we, FRED L. CoLmNs and EUGENE A. Home, citizens of the United States, residing at Cliicag-o, in the county of Cool: and State of Illinois, have invented certain new and useful Inqrrovements in Electric Switches, of which the following is a specification.

The object of our invention is to provide a new and improved switch for changing electric circuit connections. In certain of its aspects, our invention is especially adapted for circuits carrying heavy currents of electricity.

In the accompanying drawings, we have illustrated one specific embodiment of our invention which is especially adapted to have the switch terminal-s immersed in oil and in which for illustrative purposes, the switch is shown in a form adapted for the starting and runnii'ig positions of an induction motor, as will bemore fully explained hereinafter.

The more specific objects of our invention and its advantages will beeorneepporent on perusal of the following specification and claims, taken in connection with the drawings, in which F i-gure 1 is a front elevation of the device taken partly in section on the line- 1 in- Fig. 4 lookingin the direetionof the arrow. Fig. 2 is a. vertical section taken on the line 2 in Fig. 4. looking in the direction of arrow, Fig. .3, is a, partial View corresp nding to Fig. 2., shown-1g certain movable pertsin a changed relative position. Fig. #l is'e vertical section taken on the line st in Fi- 1, looking in. the direction of the arrow. iig. 5 is an elevation of an auxiliary device taken partly in section on the line 5 of Fig. 1. Fig. 6 is a diagram. illustrating suit-able circuit connections for the articular switch which we have. chosen. to s. ow in the draw Lugs.

Thev device compe iseson upper cast. iron shell adapted to be bolted to a: wall by means of the lugs 16, and a lower cast. iron shell: .18 adopted. to hose-cured. to the upper shell lfi by means of the imposed-lugs l7 and 19 and the bolts 20I These two shells form a. complete box like housing for the parts within. We make the upper shell 3L5 with its front end 15" detachable, as shown n F 1g. 1 the: two parts 15 a d 15/ bein cured together by means of the stud! Q111 114', as shown inFig. 1. Two opposite brackets or hangers 21, reinforced by ribs 22, project downwardly and inwardly from the wall of the shell 15, their lower ends carrying the horizontal. flanges 23 to which the slate slab 2 1 is secured by means of the bolts 26. This slab- 24 has th ree'holes 25 through which pass the conductors 109. Attached to the brackets 21, by means of the stud bolts 28., are the extension pieces 27 which carry projecting trunnions 29. These trunnions 29 are rotatably mounted in the respective members 27 and pinned totherespective members 30 and 32. The hard maple bar Set is secured to the member 3.0 and the walking boa-1n 3.2 by means of the respective stud bolts 31 and This bar 3-4 curries copper sockets 35- in ali-nernent with respective holes 25 in the slate slab 2.4:. The conductors 109 are soldered or sweat-ted into the sockets 35-. Eech socket 35 has its lower end tapered and adapted toreceive a correspondingly tapered sleeve 37, which may be secured. tightly there by meansoi the stud bolt 38. Each sleeve 37 has an ottset position 3.6., between which and the maple bar 3.4;, are the copper bars 39-, the steel spring 41 and. the intermediete pring r inforcing h r 4B0, all. these par-ts. being secured to the maple bar 3% by means of the bolts 118.

The. ends of the copper bars 39- are ofiset as hidiceted by the reference numeral- 2, bolts l3-possingthrough the ports, as shown in Figs. 2. and By means of. the three nuts on each.- ost these. bolts the contact torxiii-nails. 4.6 can be adjusted so that all three of th m on. one side w ll act simultane usly. The steel spring; 41 carries. copper contact terminals 4E6 adopted to coac-t with the.- fined terminals e8. Copper ribbon strips 11.01am rovided connecting the copper her- 4 9 eon. ductivel-y to the contact terminal-s 4.6. Extension springs M are seen-red. under the bolts ,13 and carry supplement ry eel 0on t-act terminal pieces 45, adapted to count with the. steel supplementary terminals 47.

The fixed contact-terminal pieces 4L8 ere oonnectexiby bolts. .50 and nuts 51,. 5.2- to the. copper members: 49, each of which. is bent upward1y,.as shown Fig. 2; and ear ries a cup 53 to receive the end of therespective conductor thereto.

The upper shell tront 1.5 has a boss 54 whichcarries erotetable shatt 55, to. the in nor end of which: the Walking beam 55 is secured by means of the key 57 and nut 58. The ends of the two walking beams 57 and 32 are connected together by means of the links 59; these connections comprising the :5 slots 59 in the Walking beam 32, so as to facilitate movement of the parts.

Fixed on the shaft is the cam plate and loosely mounted on the shaft 55 adjacent to the cam plate 60 is the lever 61 with the handle 65. The shell member 15 has a notched lug 62 adapted to be engaged by the dog 63 controlled by the hand hold 64. The helical tension spring 66 connects the arm 68 of the cam plate 60 to the stud 67 on the lever 61. The cam plate 60 has the notch 69 on its periphery normally engaged by the dog 71 plvoted on the casing at 70. This dog 71 carries an arm 72 adapted to be engaged by the adjustable stud 74 on the lever 61. This stud can be fixed at any desired adjustment by means of the lock nut 75. The dog 71 also carries another arm 71 which is engaged by a tension spring 73 tending to hold the do 71 against the cam plate 60. A stud 76 pro ecting from'thecasing member 15 acts as a stop for the lever 61. On its op osite side, the cam plate 60 has the contour 7 with decreasing radius going around the cam plate in a clockwise direction. The dog 78, pivoted at 79, is held against this cam 77 by means of the tension spring 82, engaging the arm 83. The dog 78 also carries another arm 80 with a hold 81 on the end thereof. This arm 80 is adapted to be engaged by the adjustable. stud 87 on the lever 61. At the ends of the cam 77 are the notches 84 and 85. The stud 86 in the casing plate 15 acts as a stop for the lever 61.

Pivoted on the bolt 88 is the L-shaped lever 89, one end 90 thereof, resting on the arm 80 of the dog 78, and the other end 91 being bent around the side of the casing 15 below the solenoids 94. These solenoids 94 are within-a hood 92 attached to the casing shell 15 by means of the stud'bolts 93. Each solenoid 94 has a core 95 with a stem 96 assing through a hole 98 in the arm 91.

uts 97 have screw threaded engagement with this stem 96, and thus provide for adjustment. These solenoids 94 and the associated parts constitute an overload circuit breaker, whose operation will be explained later.

' In Fig. 6, the three conductors of a three phase transmission circuit are indicated by the reference numeral 99; and 100 is an open delta startin' transformer from which taps are taken 0 to the five conductors 101 as shown. From these taps branch conductors 102, 108, 104, 105 and 106 may be taken off to supply an three phase induction motor 107. The re erence numeral 108 designates generally the particular switch which we have descrlbed as an illustrative embodiment of our invention. As shown in the diagram, it will readily be perceived that the switch is in a running position, but that by throwing it on the contact terminals of the conductors 103, 104 and 106, the motor 107 will then be connected to the half voltage taps of the starting transformer 100. 111 is a cross connector from the conductor 104, which clearly shown in Fig. 6.

It will be noted that the shell 18 is in the form of a cup adapted to hold insulating oil, a suitable approximate level for which is indicated by the reference numeral 112. It will be observed that by removing the bolts 20, this cup 18 can be lowered with its contained oil and set aside, thus making the contact members of the switch readily accessible for inspection or repairs.

The switch is shown in F igs, 1 and 2 in neutral open position, and it will readily be observed on comparing Fig. 2 with Fig. 3 that in closing the switches on either side, the terminals 45 and 47 will meet first and then the terminals 46 and 48 will meet, and in all cases, there will be a sliding movement between the pair of terminals, thus keeping them bright and more eflectively excluding oil from between them. The terminals 4547 meeting first, and breaking last, will always carry the are, thus protecting the main terminals 46 and 48. If for any reason it is necessary to remove the contact terminals for repairs this can very readily be done by withdrawing the bolts 28 and 38 and disconnecting the links 59 from the walking beam 32; and thus the maple bar 3 can be directly removed.

tion; first closing the switch to start an induction motor, then shifting it to running position, and then restoring it to normal; this will sufiiciently illustrate its applicability for other uses. To start, the operator seizes the handle -64 withdrawing the dog 63 and pulls the lever 61 over to the left as viewed in Fig. 1 until the stud 74 strikes the arm 72 and withdraws the dog 71. This movement of the lever having extended the spring 66, it follows that as soon as the dog 71 is withdrawn from the cam plate 60, the tension of the spring 66 will instantly jerk the cam plate 60 around to the left, as viewed'in Fig. 1. Thereupon the dog 78, influenced by the spring 82, will drop into th8 IIQtl1 84 and the circuit contacts will be closed as indicated by Fig. 3. The motor will t us s art supplied from the half voltage taps of he open delta autotransformer 100. As soon as the motor ets to going fast enough, the operator w1ll throw the lever clear over to the right until the stud 87 strikes the arm of the dog 78, thus withdrawing it from the notch 84, and permitting the spring 66 to jerk the cam plate 60 around to the right until the dog 78 We will now describe the mode of operadrops into the notch 85. This movement of the cam plate '60 will take place very quickly, and by means of the connecting links 59, the movable switch member Will be quickly reversed from the position shown in Fig. 3, thus cl'ianging to full running 'msition for the motor. This clock Wise movement of the cam plate will cause the earn 7 7 to engage the dog 7 8 and push it back farther until it drops Into the notch 85, the lever 61 mean While resting against the SlXlP 86. When the dog 78 has locked into the notch 85, the operator returns the lever (-51 to normal position locking it there by means of the dog (38, and thus leaving the spring 66 on a tension. Whenever it is desired to stop the motor, this can be accomplished by tripping the dog 78 by means of the handle 81, thus pern'iitti-ng the spring 6'6 to jerk the cam plate in counter clockwise direction back to the normal position, shown in Fig. 1.

In case of an overload, the solenoids 94 will be energized excessively and will pull up on their cores 95, thus causii'ig the end 90 of the lever 89 to trip the dog 78 and stop the motor.

It will be seen that We have provided mechanism by which a circuit can be closed instantly, can be changed as quickly from one arrangement to another, and can be quickly broken. The mechanism is compara'tively simple and is sure in its mode of operation.

The device is automatic in its action; it will be noted that When the switch is in its nor-marl open position, it cannot be thrown directly to full running position, but r'n-ust first be thrown to the starting position. It is further automatic in that quick action is inevitable; it is impossible for an as'tte'ndant to break or make the contacts slowly, even if he tries. This quick act-ion does away with the formation of injurious arcs and thus preserves the contact terminals, For

motors of several hundred kilowatts sup plied with current at several hundred volts, there would be very destructive arcs formed at the terminals, unless they were made or broken almost instantaneously as is the case in our device. Another point of advantage is that the contact terminals When made are pressed ti'ghtly and firmly together by the springs 'on Which they are mounted.

By means of the nuts on the bolt 43, the spring 4l can be adjusted relatively to the ends 120f the bar 39, so as to make the three contact terminals 46 on one side touch their respective 'coacti-ng fixed terminals =18 at the same instant. In this Way, the three circuits are made and broken exactly simultaneously.

All movable and Wearing par-ts are so arranged that every one can easily and replaced very little trouble and be gotten at when necessary with time" All the contact terminals are safely inoloseol in a suitable housing which is absolutely dust proof. The device can be operated by com purutively imskilled laborers, and hence the control of large ind uction motors can be safely entrusted to them. M any other ad'vai'rtages will. be apparent to those skilled in the art to which this invention relates.
