Pepper, Fort Wayne, Ind., assignor to General Electric Company, a corporation of New York Application March a, 1937, Serial No. 128,809" 9 (oi. zoo-152 The present invention relates to electric switches of the. type having liquid contact circuit closers for controlling the flow of current. a x
The object of my invention is to provide an.
improved construction and arrangement switches of this type. I
In the'accompanying drawing, Fig. 1, is an end elevation of a switch embodying my invention; Fig. 2 is .a side elevation of the switch; Fig. 3 is an exploded view of the parts for supporting the circuit closers; Fig. 4 is afragmentary view partly broken away showing the circuit closersin the circuit closing position; and Fig. 5 is a view similar to Fig. 4 showing thecircuit closers in the circuit interrupting position. a I I Referring to the drawing, I have illustrated my invention using liquid contact circuit closers of the type being claimed in applicationserial No. 759,527, filed December 26, 1933. Such circuit closers are typical of those suitable for main a switch embodying my invention; The circuit closers have. a pair of cup-shaped terminals which are separated by a diaphragm 2 of a refractory insulating material, such as a ceramic. The edges of the terminals are sealed by a bead 3 of glass which also seals the junctions between the diaphragm and the terminals. Within the space enclosed by the terminals is a suitable quantity of mercury I which forms the conducting medium between the terminals. In the manufacture of the circuit closer, the space enclosed by the terminals is evacuated and filled with hydrogen at a pressure of one or more atmospheres which increases the circuit interrupting capacity of the circuit closer. The diaphragm 2 is provided with an opening which is submerged in the mercury when the circuit closer is in the current conducting position shown in Fig; 4.
When the circuit closer is in the current interrupting position shown in Fig. 5, the opening 5 is above the mercury and the circuit between the terminals is therefore interrupted by the insulating diaphragm 2. Dueto the construction of the circuit closer, the interruption of the circuit between the terminals takes place in the mercury as the circuit closer is turned from the position shown in Fig. 4 to the position shown in Fig. 5.
The structure for supporting the liquid contact circuit closers comprises a shaft 8 which is journaled in a suitable support I. A handle 8 for rotating the shaft is fixed to one end thereof. The shaft has a squared end 9 which fits into a square opening in the handle. When the handle is in place, the squared end is upset to form a shoulder it! which holds the handle on the shaft,
with reference to the plates.
' 0n the shaft 6 are'plates H and I2 of insulating material having notches l3 and H, the sides of which fit in grooves I5 and IS on opposite sides of the shaft. The sides of the notches l3 and H cooperate with the bottom of the grooves l5 and It to key the plates to the shaft. Contacts I! are riveted in the plates, the contacts having round heads l8 which fit in complementary depressions I9 in the terminals of the circuit closers and tubular shanks which extend through the'plates. Between the plate II and theheads l8v of the contacts ar'e'clamped metal parts having tongues 2| which extend in depressions 22 in the adjacent circuit closerterminals and locate the angular position 0f the circuit closers The' parts 20 also have tongues 23 which fit in one of the openings 24 or the notches 25in the plate It The angular position of the circuit closers may be adjusted by turning'the parts. 20 so that the tongues 23 fit in a different opening or notch. The plates H and i2 are clamped together and held on the shaft by a bail 28 having eyes 21 fitting over the shaft The intermediateportion of the bail fits in notches 2 8 inthe plates i l and I2 and thereby exerts a force clamping the plates together and holding the plates on the shaft. The grooves l5 are sufficiently wider than the plate I I to permit the necessary movement of the plate ll toward the plate l2 so that the circuit closers are'firmly held between the plates. Leads 29 are soldered into the ends of the tubular'shanks of the contacts I1 and the ends of the leads are held in position by extending the leads inward-through openings in the plates. A spacing washer 3i prevents axial movement of the shaft .6 in the support I.
- In the assembly of the switch, the washer 3| and the bail 26 are assembled on the shaft 6. The circuit closers are next arranged between the plates 1 I and I2 with the tongues 2| fitting in the depressions 22 in the adjacent circuit closer terminals. er and placed on the shaft, the notches I3 and II in the plates fitting in the grooves l5 and it between the eyes 21 of the ball. The ball is then swung to a position in which it fits in the notches 28 thereby clamping the plates together and holding the circuit closers between the plates and the plates on the shaft. When in the clamping position, the intermediate portion of the bail is stretched. The clamping force therefore is due to the resilience of the bail. From one aspect, the bail can be considered as a tension member. The switch is operated by turning the shaft 5 by means of the handle 8. When the switch is in the position illustrated in Fig. 4, the circuits are completed through the circuit closers. When the switch is in the position shown in Fig. 5, the circuits are interrupted.
What I claim as new and desire to secure by Letters Patent of the United States, is:
1. In an electric switch, a liquid contact circuit closer having opposed terminals, a shaft, spaced plates on said shaft having contacts adapted to engage said terminals, and a bail having its ends connected to said shaft and its center portion engaging said plates for clamping the plates together whereby the circuit closer is held therebetween.
2. In an electric switch, a liquid contact circuit closer having opposed terminals, a shaft, spaced plates having notches non-rotatably engaging complementary portions on said shaft, contacts on said plates adapted to engage said terminals, and a bail having its ends connected to said shaft and its center. portion engaging said plates for clamping the plates together whereby the circuit closer is held therebetween and for holding the plates on said shaft.
3. In an electric switch, a support, a liquid contact circuit closer having opposed terminals, spaced members on said support carrying contacts adapted to engage said terminals, one of said contacts and said terminals having inter: fitting projections and depressions whereby the circuit closer is supported between said contact carrying members, and a tension member having its ends connected to said support and its center section engaging one or said contact carrying members for clamping said members together whereby the circuit closer is held therebetween.
4. In an electric switch, a liquid contact circuit closer having opposed terminals, contacts adapted to engage said terminals, members carrying said contacts, a support, and means including a tension member extending from said support over an edge of at least one of said contact carrying members for clamping the contact carrying members together whereby the circuit closer is held therebetween.
5. In an electric switch, a support, a liquid contact circuit closer having opposed terminals, contacts adapted to engage said terminals, one
of said terminals and said contacts having interfitting portions whereby angular displacement of the circuit closer relative to the contacts is prevented, members carrying said contacts, at least one of which is movable toward the terminals of the circuit closer, and a tension member having its ends secured to said support and having an intermediate portion engaging an edge of said movable contact carrying member for clamping said members together.
6. In an electric switch, a liquid contact circuit closer having opposed terminals, contacts adapted to engage said terminals, members carrying said contacts, ashaft non-rotatably carrying said members, one of said members being movable lengthwise of said shaft, and means clamping said members together whereby the circuit closer is held therebetween.
